Definitions

  • the aim of the invention is to take constructive precautions to realize especially for multi-pole relays that simplify an automated production process and one Tolerance-free assembly of the magnet system on the base body as well enable a precise guidance of the slide, the return spring and the anchor as well as an improved suspension of the operating mechanism.
  • the modular structure applies special attention to the relay.
  • a compact design for multi-pole versions of the relay sought.
  • this goal is achieved in that the Base body as a substantially flat base parallel to Coil axis is arranged below the coil that the at least one contact spring between the coil and the base extends parallel to the coil axis, while the connection elements led perpendicular to the outside through the base are that the anchor with its cross leg on the free End of the longitudinal leg is mounted on the core that the Longitudinal leg of the armature extends above the coil that the cross leg of the core facing upward to form a pole face of the working air gap, and that the magnet system lateral attachment processes in the area of the core transverse leg owns, with the top of the Interlocking base.
  • they are the working air gap forming end sections of the longitudinal armature and Core cross leg widened in a T-shape, creating the magnetic Resistance in the area of the working air gap reduced is.
  • the attachment extensions are formed facing downwards on the lateral leg of the core.
  • the attachment extensions are on the core on both sides of its widened end section molded downwards.
  • the attachment extensions are hook-shaped designed, for example as snap noses, so that these with Recesses formed on the base of the base can be locked are, so that magnet system and base in a kind of Press fit are connected to each other. On the one hand, this contributes stiffening of the overall system, on the other hand no additional effort to attach the magnet system necessary on the base.
  • fastening chambers for flange extensions in the base molded on the coil former which plug-in channels for Have attachment of winding connection elements, so that the flange extensions in the area of the anchor bearing in the fastening chambers are attached by insertion.
  • a support pin is formed on the base, which with is provided with a latch. This latch is with one Cross bar hooked between the bottle extensions on Coil body is molded, so that an additional attachment of base and magnet system is realized.
  • the advantage of the features mentioned is that the distance the contacts to the working air gap are set with low tolerance is, in that the core or the bobbin directly is connected to the base as a contact carrier. On this avoids the accumulation of tolerances. Due to the extremely low tolerance arrangement of the magnet system and Socket to each other will not only be a precise guide of Slider achieved, but also a precise definition of the Over stroke for the contact elements allows.
  • the contact springs are advantageously actuated via a substantially U-shaped coupled to the anchor Slider, which with its side arms the magnet system engages, and the central portion of the contact springs acts. Also on the lower edge of the middle section molded on the slide down actuators.
  • the number of actuators corresponds to the number of the contact sets contained in the relay, consisting of a contact spring and at least one counter-contact element.
  • the actuators can be easily on the preferably as a plastic molded actuator Form without any significant additional effort.
  • the actuators protrude into contact chambers on the base, in which the contact sets are arranged. Through the side walls of the contact chambers are the individual contact sets from each other isolated.
  • Each base has a pair of upward-facing guide rails attached, which one on the outer edge of a Slider side arms molded outward projecting guide pin engages and this during the up and down movement of the Secures slide against lateral displacement.
  • a U-shaped armature spring which with a first arm is attached to the anchor longitudinal leg, in Middle section arranged approximately parallel to the anchor cross leg is and with the second arm in a recess between Core and bobbin parallel to the longitudinal core is attached.
  • the recess between the core and the bobbin is best in the form of a separate space on the bobbin formed.
  • the second arm of the anchor spring, the in the recess between the bobbin and core is inserted, preferably equipped with a latch, which is hooked into the core directly above is.
  • Anchor spring including the anchor firmly connected to it on the one hand and bobbin with core arranged therein on the other not easily possible.
  • the latch is for example by punching from the spring plate and then To bend so that they are force and adapts positively to the embossing in the core. additionally is the fixation of the anchor spring by the in the Base integrated support pin, which improves the height positioning of the magnet system in the area of the coil connection side serves.
  • Relay according to the invention results in a very simple assembly process, which is also easy to use or specialized workers.
  • the base is preferred with the contact and connection elements Equipped to assemble the magnet system. there the formation of fastening and contact chambers proves itself on the base, which in this context is a pocket serve for the components to be included, as another Advantage.
  • the anchor spring is preferably attached to the anchor in advance. When assembling the magnet system is preferred first insert the core axially into the bobbin until the cross leg of the core on one end of the coil body is applied. Then the arm containing the locking lug the armature spring into the recess between the coil body and Inserted the core until the locking lug is in the position provided in the core Embossing hooked. Expediently, the Slider hung from below on the armature spring lobe, with which the assembly of the magnet system including the coupling the slide is complete. In the last assembly step are only magnet system and base by means of Fasteners according to the invention connected together.
  • the relay according to the invention consists in its main components from a mounted magnet system 1, one attached to the anchor U-shaped slide 8, a base 6, by contact springs 71 and counter-contact elements 72 formed contact sets and winding 74 and contact connection elements 73 ( Figure 1).
  • the connection elements are vertical through the base 6 led to the outside.
  • To increase the magnetic conductivity in the working air gap between yoke 33 and pole face 43 of armature 4 are yoke 33 and pole face 43 in relation to widen anchor 4 or core 3.
  • guide pin 84 are formed by guide rails provided on the base 6 66 guided, the guide pin 84 in pairs reach around to the side and fit them positively.
  • the slide 8 is in particular in the deflection the armature movement on the contact springs 71 against lateral Moving secured (see also Figure 2 and Figure 3).
  • Figure 2 also shows the attachment of the winding connection elements 74, which at its upper end in in the flange extension 22 contained plug-in channels 23 are inserted.
  • the winding connection elements are to facilitate installation 74 cranked in the middle. With its free end project the winding connection elements 74 vertically through the Base plane of the base 6 through.
  • FIG. 4 shows those components of the magnet system 1, which are used to attach the armature spring 5.
  • the bobbin 2 clearly shows the flat cuboid free space 24 recognize that receives an arm of the armature spring 5.
  • the one in the Clearance 24 inserted arm of the armature spring 5 contains one Latch 51, which is in an embossing 35 on the underside of the Core 3 is hooked.
  • the one above the longitudinal anchor leg 41 lying arm of the armature spring 5 is on the longitudinal arm leg 41 attached rivet warts 44 firmly connected to the anchor 4, so that this is biased by the armature spring 5 and at the same time is stored.
