Definitions
- the invention relates to a power relay for a vehicle, in particular a commercial vehicle.
- Generic power relays are used in vehicle technology, especially in commercial vehicles.
- the power relays are here used on the one hand to electrically disconnect the vehicle battery from the electrical system.
- Such relays are used to switch electric motors of adjusting devices (e.g., hydraulic pump or lifting platform).
- Such a power relay must be able to switch currents up to a current of about 300 amperes at low voltage, typically 12 to 24 volts, and must be solidly built accordingly.
- Conventional relays used for this purpose typically consist of a cup-shaped body of metal (e.g., iron or steel) in which a magnetic coil, a magnetic yoke, and a magnet armature connected to a contact bridge (double contact) are housed.
- the power relay To connect the power relay to a load circuit to be switched in the vehicle, the power relay typically includes solid metal studs (threaded bolts) typically 0.5 to 1 cm in diameter. Cable lugs of the connection lines of the load circuit to be switched are fixed in a contacting manner by means of nuts (contact nuts) on these connection pins.
- Such power relays are known in particular from DE 10 2010 018 755 A1 and DE 10 2010 018 738 A1.
- the conventional power relays are comparatively heavy and expensive to manufacture.
- Another problem of the power relays conventionally used is that currently a variety of different construction variants are used, which are different distances of the
- CONFIRMATION OPiE Connection bolts and different mounting options for the relay housing (eg laterally on the housing pot, on the connection side or on the opposite to this bottom of the relay housing) differ.
- the invention has for its object to provide a particularly rationally manufacturable and easy-to-build power relay for a vehicle, especially a commercial vehicle.
- the power relay comprises a housing which is formed from a connection socket and a housing pot mounted thereon. Two connection bolts are inserted in the connection socket, via which the power relay can be contacted with connecting cables of an external load circuit to be connected.
- the power relay further comprises a coil assembly arranged in the housing with a magnet coil and a corresponding magnet armature. The armature is in this case coupled via a force transmission member with a contact bridge and under the action of a magnetic field generated by the magnetic field displaceable in the housing, that the contact bridge is reversibly movable between a closed position and an open position.
- the closed position is in this case characterized in that the contact bridge bridges the connecting pins in an electrically conductive manner, as a result of which the power relay is switched on.
- the open position is characterized in that the contact bridge is de convincediert of the terminal bolt, so that there is no conductive connection between the terminal bolt and the power relay is thus switched off.
- the housing pot is designed as a plastic injection-molded part. This allows for a significant reduction in manufacturing and material costs, as well as significant weight savings, as compared to conventional power relay provided with a metal can.
- Also in the connection socket is preferably a plastic injection molding.
- this can optionally be a bistable relay which permanently maintains both the closed position and the open position in the de-energized state of the magnet coil, or it can be a monostable relay.
- the power relay may be formed as normally open or normally closed, the relay automatically at
- both bistable and monostable designs of the power relay are realized according to the construction principle of the invention.
- the coil assembly further comprises a magnetic yoke.
- the yoke expediently comprises a torsionally stable structure which is rotatably received in this over the entire axial height of the housing pot.
- the axial height here is the extension of the housing pot along the housing top axis perpendicular to the bottom of the housing pot.
- the torsionally stable structure of the magnetic yoke is formed in an expedient embodiment by a one-piece, U-shaped angled bracket whose legs surround the magnetic coil parallel to its coil axis.
- the housing pot preferably has an at least approximately rectangular cross-section at least in its interior, the magnet yoke, in particular the yoke, extending parallel to two of the four sidewalls in the manner of a crossbeam and supported on both sides by the two remaining side walls. Due to the rotationally fixed receiving the magnetic yoke, the housing pot initiates a torque acting on it, which is caused for example by tightening the contact nuts, in the torsion stable running magnetic yoke. In a torsion of the housing pot, therefore, the yoke, in particular the bracket must always be twisted, which in turn relieves the housing pot. As a result, material fatigue or even breakage of the housing pot is counteracted.
- the terminal base is preferably also coupled to the magnetic yoke so as to be secure against rotation, for example by virtue of the magnet yoke engaging in form-fitting manner with corresponding projections in corresponding recesses of the terminal socket.
- torques exerted on the connection socket are not transferred to the magnetic yoke, but only indirectly via the housing pot. Rather, at least a portion of these torques is introduced directly from the terminal socket in the magnetic yoke, which in turn relieves the housing pot, and in particular the connection between the housing pot and the terminal socket.
- the power relay in the context of the invention can be a purely electromechanical component, in which the magnetic coil is activated (energized) solely on the basis of external control signals and deactivated (switched off).
- the power relay additionally comprises a control electronics accommodated in the housing for controlling the magnetic coil.
- the control electronics converts external control signals (which in this case can also be output, for example, as pulse signals, in particular in digital form) into a corresponding control current for the magnetic coil.
- control electronics further includes other functions, such as current or voltage measurement between the terminal pins and / or protection functions, a forced shutdown of the power relay in case of over- and / or undervoltage, overload or - in multi-pole versions of the power relay - a fault current or an asymmetrical current distribution cause.
- the power relay comprises a number of signal terminals, each of which is in each case connectable to an external signal line.
- the signal connections are expediently, as well as the connection bolts for the load current, fixed in the connection socket.
- the signal terminals serve to supply at least one electrical control signal to the power relay and / or to output at least one electrical state signal by the power relay.
- at least one of the signal terminals for supplying an electrical supply voltage or an electrical reference potential, in particular ground, also provided.
- the signal connections are in this case contacted directly with the magnetic coil.
- the control electronics provides additional functions (for example, measuring functions, protective functions, bus communication, etc.). In the latter case, the signals supplied via the signal terminals are generally only indirectly used to actuate the magnetic coil.
- connection socket is preferably connected in a fluid-tight manner to the housing pot by means of a hardening potting compound, for example an epoxy resin.
- a hardening potting compound for example an epoxy resin.
- the housing pot engages on the outside with a collar around the radial web of the connection socket, wherein the collar projects axially beyond the radial web.
- the collar of the housing pot thus surrounds the molded onto the terminal base radial bar in the manner of a balustrade.
- a trough-like receptacle (referred to below for short as "tub") for the potting compound is formed by the collar and the connection pedestal. In the assembled state of the power relay, this tub is completely or at least partially filled with the potting compound.
- connection conductor which is preferably formed by a bent sheet metal stamped part
- connection conductors is in this case preferably passed through in the region of the tub through the connection socket.
- the collar of the housing pot is provided in the region of the tub with at least one radial contour.
- the or each radial contour of the collar can be formed by a radial recess (which reduces the material thickness of the collar) or a radial projection (which increases the material thickness of the collar).
- Corresponding to the or each radial contour at least one mating contour is formed on the connection socket in the region of the trough.
- the radial contour and the corresponding mating contour form a form-locking connection with the potting compound, by means of which the connection socket and the housing pot are locked together in the circumferential direction, ie tangentially to the axis of the magnet coil and of the housing pot.
- the radial contour and the corresponding mating contour continue to undercuts, due to which the housing pot and the connection socket by positive locking of the potting compound with the radial contour and the mating contour in ra Dialer direction are locked together.
- the radial contour is designed as a latching nose, which engages over the radial web and thus latched to the housing pot.
- the cause of the high gas pressure may in this case consist in the warming-related expansion of the air in the housing interior and / or in the evaporation of residual moisture of the air taken up in the housing interior.
- the cause of the air heating can in turn be a switching arc or the heating of the current-carrying parts due to the current flow (in particular a short-circuit current).
- the explosion or the uncontrolled bursting of the housing can lead to dangerous situations, in particular a short circuit of live parts with mass and an associated risk of fire or personal injury, and must therefore be excluded.
- an overpressure protection is provided in an advantageous embodiment of the power relay in the housing - and preferably in the housing pot - which releases a gas ejection opening in the case in the case of a critical overpressure, and thus ensures a controlled pressure equalization with the environment.
- the overpressure protection can be formed by a separately manufactured and inserted into the housing pot (or possibly in the connection socket) valve, in particular by a spring-loaded ball valve or a tearing in the overpressure membrane (optionally semi-permeable by nature, ie gas-permeable, but not liquid permeable can).
- the overpressure protection but in the housing (and in particular in the housing pot) integrally integrated, in particular to the housing molded.
- the overpressure protection is formed in particular by a predetermined breaking point, which bursts in the overpressure case and thus releases the gas ejection opening to relieve the remaining housing areas.
- the predetermined breaking point preferably has a curved, for example U-shaped, V-shaped, or trapezoidal, shape and thus surrounds on three sides a tab-like portion (hereinafter "flap") of the housing, which forms the closure of the overpressure protection
- the lug is expediently designed as a film joint along a connecting line extending between the ends of the predetermined breaking point
- a gas ejection opening having a defined shape and size is formed by the lug framed by the predetermined breaking point is bent out of the housing wall, but prevents the tab here breaks off uncontrollably, thereby counteracting a possible risk to persons or damage adjacent parts
- the predetermined breaking point esp special a keyhole shape, that is U-shaped with a circular prepared ground.
- the power relay is provided in an expedient development with a safety function that generates a warning signal after the failure of the predetermined breaking point and / or the power relay forcibly switches to a safe state.
- the safety function comprises a forced shutdown, by means of which the power relay permanently shuts off - by decontacting the contact bridge from the terminal bolts - and is thus irreversibly shut down.
- the fuse function of the power relay - in adaptation to the particular application - but also include the switching of the power relay. For example, a power relay used as a battery switch in a commercial vehicle must remain switched on even in the event of a fault, since otherwise the electrical supply of the vehicle electrical system - if necessary while driving - would collapse.
- the forced shutdown detects the overpressure case independently of the state of the predetermined breaking point, for example by a separate overpressure sensor which is triggered in a critical overpressure case.
- the forced shutdown is triggered directly by the bursting of the predetermined breaking point.
- an electrical safety line is mechanically coupled to the predetermined breaking point such that the safety line is severed in the event of failure of the predetermined breaking point.
- the fuse line is here - directly or indirectly - in operative connection with the solenoid, so that their severance causes the forced shutdown of the power relay.
- the fuse line may be part of the power supply of the solenoid or part of a signal circuit connected to the possibly existing control electronics, for example.
- the fuse line is electrically switched through in the case of failure of the predetermined breaking point, in which case the connection (ie the emergence of a conductive connection via the fuse line), the forced shutdown triggers, or that the state of the predetermined breaking point another sensor is controlled.
- the coil assembly is preferably designed as a self-stable (stable in itself) and contiguous structural unit.
- the coil assembly is thus designed such that it holds together without the surrounding parts of the housing. This makes it possible to assemble the coil assembly outside the housing, which in particular accommodates an automated manufacturing, and to use as a whole in the housing.
- Core element of the self-stable coil assembly is in an advantageous embodiment of the power relay a trained by a plastic injection molded part, one-piece support body on which the magnetic coil is wound directly.
- the carrier body preferably also carries the magnet armature, which for this purpose is slide-mounted directly in the carrier body.
- the carrier body comprises at least one pocket which serves to receive a pole shoe of the magnetic yoke and, if present, at least one permanent magnet. Permanent magnets are provided here in bistable designs of the power relay.
- the or each pocket preferably has a wall with a defined wall thickness between 0.2 mm and 0.5 mm, in particular at about 0.3 mm, by which the corresponding pole piece of the magnetic yoke is spaced from the guided inside the support body magnet armature ,
- a wall with a defined wall thickness between 0.2 mm and 0.5 mm, in particular at about 0.3 mm, by which the corresponding pole piece of the magnetic yoke is spaced from the guided inside the support body magnet armature ,
- a holder or at least installation space for at least one freewheeling diode and / or a holder for a thermal fuse and / or a holder for a switching position contact for detecting the switching position of the power relay are further formed on the carrier body.
- a thermal fuse is here an electrical or electronic component understood that opens by melting or mechanical movement under the influence of external heat generation (unlike a fuse so not under the effect of flowing through the component current) and thus interrupts the guided over the thermal fuse circuit.
- this carrier body is designed as a multi-functional part that can be used unchanged in a variety of different types of power relay, especially in types with and without freewheeling diodes, designs with and without thermal fuse as well as designs with and without switch position contact.
- the brackets are thus on the support body in particular also formed in designs of the power relay, in which the respective functional component, ie the freewheeling diode, the thermal fuse or the signal contact are not provided.
- the coil assembly is preferably attached to the terminal socket, wherein a snap connection is preferably used for this attachment. This makes it possible to mount all electrically and by mechanical movement cooperating parts of the power relay outside of the housing.
- a coupling rod is provided in an expedient embodiment of the power relay, which extends along a coil axis of the magnetic coil.
- the coupling rod is slidably mounted in a central part of the magnetic yoke.
- the contact bridge is attached to the coupling rod.
- the coupling rod is in this case, in an advantageous embodiment of the invention, slidably mounted on its armature-distant side (thus in the region of the contact bridge) in the connection base.
- the coupling rod dives in particular with a - in the connection base slidably mounted - bearing section through the contact bridge.
- control electronics present in this case are preferably arranged outside the magnetic yoke, and in this case in particular parallel to one of the side faces of the housing pot.
- control electronics is thus arranged in the cold area of the power relay, whereby the control electronics is spared.
- multipolar embodiments of the power relay are preferably provided. These multipolar versions ments of the power relay serve, in particular, to switch multiphase load circuits simultaneously or to switch single-phase load circuits in parallel through a plurality of switching units. The latter has the particular advantage that the load acting on the relay during switching can be distributed over several poles.
- Multipole embodiments of the power relay are hereby advantageously realized in that a plurality of coil assemblies are fastened together on one and the same terminal base, said terminal base carries two connecting bolts for each coil assembly.
- the housing pot preferably carries both on a side surface and at its bottom each have a mounting surface which is provided with screw holes for receiving fastening screws.
- the power relay can either be mounted directly or - to adapt to different hole distances of the installation environment - via adapter plates by screwing.
- the respectively provided in the mounting surfaces of the housing pot screw openings are preferably realized by threaded sleeves made of metal, which are pressed into openings of the plastic material of the housing pot or encapsulated with the material of the housing pot.
- the control electronics provided in this case are provided with a contact cleaning function.
- the control electronics are set up to control the magnetic coil several times at short intervals in a contact cleaning mode. Due to the multiple control thus an artificial contact bouncing is generated in which the contact bridge repeatedly beats against the connecting bolt. In this way, optionally adhering to the contact points contaminants are abraded, whereby low contact resistance can be achieved or maintained.
- the control electronics causes the contact cleaning only when there is no electrical voltage across the terminal bolt, so that the artificial contact bouncing is done without load. To this Way switching arcs are excluded in the contact cleaning function.
- control electronics are preferably connected to the terminal bolts.
- the control electronics are set up to pick up the electrical voltage dropping between the connecting bolts and to detect them by measurement.
- a supply voltage for the control electronics is preferably tapped off via the connection bolts.

- the pole shoes 28 and the permanent magnets 29 of the magnetic yoke 25 are in two opposite in a lower platform 43 of the carrier body 40 introduced pockets 44 a.
- each of the two pockets 44 is bounded on the inside - thus towards the hollow interior of the column 41 - by a thin wall 45 of the carrier body 40, which has a defined, everywhere constant wall thickness of 0.3 mm.
- a defined gap width between the magnetic yoke 25 and the armature 24 is set.
- the carrier body 40 as can be seen in particular from FIG. 8,
- the carrier body 40 thus has the respectively molded holders 46 to 50, even if not all of the above-described functional components (ie the switch position contact 31, the free diodes 34, the thermal fuse 35, the auxiliary conductor 36 or the damping element in a particular design of the power relay 1 37) are present.
- the circuit board 21 shown in Fig. 3 is formed of two sections 60 and 61, which are hinged together via a film hinge 62 and therefore are bendable from a plain initial state in the illustrated in Fig. 3 L-shaped arrangement.
- the portion 60 carries a control electronics 63.
- the section 61 includes mainly contact points for making electrical contact with the fixed contacts 32 of Switch position contact 31, the coil terminals with the freewheeling diodes 34, the thermal fuse 35, the auxiliary conductor 36 and the solenoid 30th
- the board 21 is optionally also available. However, it carries in this case, no control electronics 63, but only traces for contacting the magnetic coil 30 and the possibly existing electrical functional elements with the signal terminals 13. Alternatively, the board 21 is replaced with purely electromechanical types of power relay 1 by wire conductor.
- the carrier body 40 is first with the solenoid 30, the yoke 25, the armature 24 connected to the coupling rod 23 and the compression springs 38, 39, the contact bridge 22 and the optional electrical functional components (ie the switch position contact 31st , the free-wheeling diodes 34, the thermal fuse 35 and / or the auxiliary conductors 36) and equipped with the damping element 37.

- the coil assembly 20 is clipped from below onto the previously completed in an injection molding connection socket 3.
- the connection base 3 is provided on its underside with molded snap hooks 64 (FIG. 3), which engage on both sides under the upper platform 42 of the carrier body 40.
- the yoke 27 of the magnetic yoke 25 furthermore engages with two shaped projections 65 (FIGS. 3 and 4) in a form-fitting manner in complementary-shaped depressions on the underside of the connection base 3.
- the bracket 27 of the magnetic yoke 25 in the clipped state rotationally fixed with respect to a rotation about the axis of the magnetic coil or the respective axis of the connecting bolt 10 is connected to the terminal socket 3.
- connection points in the area of Section 60 soldered to the leads 14 of the signal terminals 13.
- connection points in the region of the section 61 are soldered to terminals of the magnet coil 30 as well as the existing electrical functional elements (ie optionally the fixed contacts 32 of the switch position contact 31, the freewheeling diodes 34, the thermal fuse 35 and / or the auxiliary conductor 36).
- the board 21 In its mounting position, the board 21 extends with its portion 60 parallel to a leg of the bracket 27, wherein the portion 60 is disposed outside of the bracket 27. With its portion 61, the board 21 extends perpendicular to the coil axis, wherein it engages under the yoke 25 and the armature 24.
- auxiliary conductors 36 are soldered to (voltage tap) terminals 66 ( Figures 3 and 13).
- the connections 66 are in this case assigned in pairs to the connection bolt 10. One of the terminals 66 is thus contacted with one of the connecting bolts 10, while the other terminal 66 is contacted with the other connecting bolt 10.
- the connections 66 are welded in advance to the respective associated connection bolt 10 and, together with this, are encapsulated with the plastic material of the connection socket 3.
- the housing pot 4 After mounting the coil assembly 20 and the board 21 to the terminal base 3, the housing pot 4 is slipped over the coil assembly 20 and the board 21 and locked with the terminal base 3 and screwed, whereby the housing 2 is closed.
- the bracket 27 of the magnetic yoke 25 is in such a way in the housing pot 4, that its legs in the manner of cross beams between two opposite side walls 6 of the
- Housing pot 4 measured - height of the housing pot 4 rotatably received in this.
- the bracket 27 thus stiffened due to its torsionally stable structure the housing pot 4 against axial torques, as they are exercised in particular when tightening the contact nuts on the connecting bolt 10.
- the connection base 3 with a circumferential radial web 70 rests on a circumferential shoulder 71 (FIGS. 3, 12 and 13) in the wall of the housing pot 4.
- the housing pot 4 in this case engages with a peripheral collar 72 (FIGS. 3, 12 and 13) delimiting its opening on the outside around the radial web 70 of the connection socket 3 and beyond it.
- the collar 72 thus surrounds the upper side of the radial web 70 like a balustrade and, together with the connecting base 3, forms a trough-shaped structure, which can be seen in FIGS. 12 and 13, which is referred to below as a trough 73.
- this trough 73 is filled with a first liquid and curing in the course of a curing phase potting compound 74.
- potting compound 74 a two-component system consisting of an epoxy resin and a mixed hardener is used as potting compound 74.
- connection conductors 14 With the potting compound 74, the feedthroughs of the connection conductors 14 are also sealed. For this purpose, the connection conductors 14 are guided through the connection base 3 in the region of the trough 73. The passages of the connecting bolts 10 through the terminal socket 3 are sealed separately from the trough 73 by potting compound.
- a number of radial projections 80 are provided along the inside of the collar 72 - and in particular in the straight sections of the collar 72 protrude inwardly from the inner wall of the collar 72.
- the radial projections 80 act on the one hand as locking lugs which engage around the radial web 70 of the connection socket 3 and thus latch in its mounting position.
- each radial projection 80 is provided on both sides with an undercut 81, so that each radial projection (80) has a dovetail-shaped contour when viewed from above. Due to the undercuts 81, the radial projections 80 dig into the potting compound 74, whereby both a rotation of the Housing pot 4 relative to the terminal base 3 and a radial bulge of the side walls 6 of the housing pot 4 is prevented.
- Housing pot 4 acting forces the potting compound 47 is entrained with the housing pot 4 and this dissolves from the outside of the terminal socket 3, a number of mating contours in the form of protrusions 82 are formed on the top of the terminal socket 3.
- the respective inner edges of these projections in turn here forms an undercut 83, which digs into the potting compound 74.
- the power relay 1 is multi-pin, in particular two-pole or three-pole formed.
- one of the number of poles corresponding number of coil assemblies 20 are connected to a common terminal socket 3, wherein in the connection socket 3 in this case, each 2 connector pin 10 are fixed for each coil assembly.
- a separate circuit board 21 may be provided for each coil assembly 20 or a common circuit board for all coil assemblies 20.
- multipole designs of the power relay 1 is preferably a - preferably partitioned by transverse walls - housing pot 4 for common recording of all coil assemblies 20 is provided.
- FIGS. 12 to 14 show the power relay 1 in the fully assembled state. It can be seen from these illustrations that the connection bolts 10 also each form fixed contacts of the main switching device of the power relay 1 provided for switching the load circuit. The protruding from the bottom of the terminal socket 3 in the housing interior 8 ends of the connecting bolts 10 are each provided with a contact element 90 for this purpose.
- the corresponding moving contact of the main switching device forms the contact bridge 22, which in each case comprises a counter-contact element 91 in opposition to each of the contact elements 90.
- the mating contact elements 91 are electrically short-circuited within the contact bridge 22.
- FIGS. 12 and 13 show the power relay 1 in an open position in which the mating contact elements 91 are lifted off the contact elements 90
- the magnetic coil 30 is energized with reverse polarity.
- the holding force generated by the permanent magnets 29 is compensated, so that the magnet armature 24 is withdrawn by the return spring 38 of the core 26 and thus pressed into the open position shown in FIG. 12 and 13.
- the armature 24 in this case takes over the coupling rod 23 again with the contact bridge 22, whereby the counter contact elements 91 - are disconnected from the corresponding contact elements 90 - with separation of the electrical connection between the connecting pins 10.
- damping element 37 intercepts this movement and thus prevents springing back of the formed from the armature 24, the coupling rod 23 and the contact bridge 22 unit in the direction of the closed position. In addition, the play of the components of the coil assembly 20 is reduced by the damping element 37.
- each of the two switching positions of the power relay 1 is stable even in the de-energized state of the solenoid 30.
- the magnetic coil 30 must be energized only temporarily.
- the coupling rod 23 protrudes with a bearing portion upwards, ie beyond the armature remote side of the contact bridge 22 addition.
- the bearing section emerges here in an aligned bearing opening 92 of the connection socket 3, so that the coupling rod 23 is also slidably mounted in the connection socket 3.
- the section 60 of the circuit board 21 is arranged in the assembled state of the power relay 1 between a leg of the bracket 27 and the adjacent side wall 6 of the housing pot 4.
- the arranged on the portion 60 control electronics 63 is thus shielded by the bracket 27 thermally opposite to the heat generated during the energization of the magnetic coil 30.
- the control electronics 36 is in a cold area of the housing 2, whereby premature aging of the control electronics 63 is prevented.
- the control of the solenoid 30 is carried out either directly via the signal terminals 14 or via the control electronics 63, which in turn is supplied in the illustrated embodiment, via the terminals 66 and the auxiliary conductor 36 with voltage.
- the control electronics 63 controls the solenoid 30 in response to external or internal control commands, which are supplied to the control electronics 63 via the signal terminals 13. Via the connections 66, the electronic control unit 63 furthermore determines, in the switched-on state of the power relay 1, the voltage dropped across the connection bolt 10 as a measure of the load current flowing through the power relay 1 or for the detection of the relay position.
- the electronic control unit 63 optionally implements an overload shutdown and a short-circuit shutdown by automatically moving the power relay 1 into the open position when the detected load current exceeds predetermined threshold values.
- the control electronics 63 optionally also comparatively evaluate the voltages respectively dropping via the connecting pins 10 of the individual poles in order to reduce the power consumption. Relay 1 - depending on the design - to switch off on detection of a fault current or an asymmetrical current distribution.
- control electronics 63 optionally has a contact cleaning function.
- the control electronics 63 controls the solenoid 30 at regular time intervals several times at short time intervals successively, so that an artificial contact bounce is generated.
- the contact bridge 22 repeatedly strikes against the connection bolts 10, as a result of which any adhering impurities which may be adhering to the contact elements 90 and the countercontact elements 91 are rubbed off.
- the control electronics 63 in this case first checks the electric voltage applied across the terminal bolt 10 and only switches to the contact cleaning mode when this voltage has a vanishing amount, and the power relay 1 can thus be switched load-free.
- this overpressure safety device 100 is formed by a curved groove, which locally reduces the material thickness of the housing bottom 7 and thereby acts as a predetermined breaking point 101. Due to the predetermined breaking point 101, an approximately keyhole-shaped tab 102 is delimited from the housing bottom 7 from three sides. Between the ends of the predetermined breaking point 100, thus at the narrow end of the keyhole-shaped tab 102, a further groove extends, which has a smaller groove depth compared to the predetermined breaking point 101 and therefore acts as a film hinge 103.
- the predetermined breaking point 101 is dimensioned such that they bursts when the pressure in the housing interior 8 exceeds a critical limit of, for example, about 2 to 3 bar. In this case, the tab 102 is bent around the film hinge 103 to the outside, thus giving a
- the power relay 1 is on the inner wall of the
- Housing bottom 7 across the predetermined breaking point 101 and the tab 102 laid electrical signal line in the form of a vapor-deposited or glued trace whose electrical resistance is queried by the control electronics 36.
- the signal line is thereby automatically cut when bursting the predetermined breaking point 100, which is detected by the control electronics 63 due to the sudden increased volume resistance.
- the control electronics 63 puts the power relay 1 in a safe state.
- the control electronics 63 triggers a permanent forced shutdown of the power relay 1 in order to force an exchange of the power relay 1.
- the housing pot 4 bears on the outside both on a side wall 6 and on the housing bottom 7 each have a mounting surface 110.
- Each mounting surface 110 four screw holes 111 are introduced at which the power relay 1 as intended mounted either directly or via an intermediate adapter plate by means of corresponding mounting screws can be.
- the screw holes 101 are preferably formed by threaded sleeves made of metal, which are pressed into corresponding recesses (blind holes) in the plastic material of the housing pot 4 or screwed or encapsulated with the plastic material.
