Definitions

  • the invention relates to the arrangement of a relay with connection pins emerging to a bottom side and a plug adapter lying below the bottom side, the adapter having an insulating base in which conductor segments of a lead frame are fastened in a plane parallel to the bottom side, the conductor segments each making contact Recesses for cohesive contacting, in particular solder contacting, of the connecting pins and also each have connecting lugs bent in one piece perpendicular to the bottom side.
  • the invention also relates to a method for producing such an arrangement.
  • connection elements of relays are designed in accordance with the intended use, that is, either as solder pins for directly soldering the relay into a printed circuit board or as flat plugs for plug-in contacting in a socket.
  • Sockets have been known for a long time, which are soldered into a printed circuit board by means of soldering pins and have plug sockets on their upper side for receiving a pluggable relay.
  • the aim of the present invention is therefore to convert a soldering relay into a plug-in arrangement, this arrangement being achievable with as little assembly effort as possible and having the smallest possible dimensions.
  • plug connections for carrying high currents should be used, and a high stability of the combined arrangement should also be able to withstand high plug-in forces.
  • this object is achieved with an arrangement of a relay and an adapter of the type mentioned at the outset in that the connecting lugs of the adapter are designed as flat plugs that both the space between the bottom side of the relay and the base and the outlet region of the flat plugs on the underside of the base are enclosed by a peripheral wall and that at least the latter area is filled with potting compound.
  • flat plugs are provided from the outset in the arrangement according to the invention, that is to say so-called Faston or Quick Connect plugs, which are already used because of the occurring Mating forces require a corresponding material cross-section and can also carry high currents with this cross-section.
  • the base itself is enclosed on its upper side facing the relay and on its lower side by a peripheral wall, so that the outlet area of the flat plugs, whose conductor segments can be anchored in the base by plugging in or embedding, is not only sealed by an additional potting, but also is stabilized.
  • the entire adapter arrangement with the integrally soldered or welded relay thus results in a uniformly compact new part which is easy to handle and is suitable for use even with high insertion forces.
  • the peripheral wall of the base can be integrally formed on it, so that it is trough-shaped both on the top and on the bottom. In this case, it is appropriate that the upper edge of the peripheral wall overlaps the lower edge of a housing cap of the relay.
  • the space between the relay and base including the overlap gap can also be filled with potting compound, which gives the entire arrangement additional stability. In this case, the relay itself must be closed so far beforehand that the sealing compound cannot run into the interior of the relay. But it is also possible to design the peripheral wall on the base as an extension of a relay cap, so that the gap between the extended relay cap and the base is sealed by casting the underside of the base. The space between the relay and base is automatically sealed; but in this case it can also be filled with casting compound for stabilization.
  • the tabs it is also possible in another embodiment of the invention to allow the tabs to run upwards from their point of exit from the base - on the underside or on the circumferential side of the base, perpendicular to the base plane, so that they run along one or more outer sides of the relay extend up to and beyond the relay top, whereby this relay top side then becomes the plug connection side of the overall arrangement, that is to say the relay is upside down.
  • the tabs it is expedient for the tabs to be fixed on the outside of the relay by means of an overlaid frame-shaped sleeve and to be insulated from the outside. This sleeve can then also form the peripheral wall for the base and a trough-shaped receiving space for the sealing compound.
  • An advantageous method for producing an arrangement according to the invention is that a lead frame with preformed conductor segments connected via intermediate webs and with likewise preformed flat plugs in a base is pre-fixed - by plugging in or embedding - that the intermediate webs are then separated out so that a relay is also used Connection pins are placed on the base and the connection pins are integrally connected, preferably soldered, to the conductor segments, and finally a cavity enclosed by a peripheral wall in the region of the base is filled with potting compound. It would also be conceivable to embed previously separate conductor segments in the base material instead of a one-part or two-part lead frame with intermediate webs, but this would require additional effort for holding the individual parts in the injection mold.
  • this type of embedding would have the advantage that no separating processes for intermediate webs would be required on the finished base and that the finished base would have no other openings apart from the contact recesses; that would be an advantage if, for example, the relay itself on the underside were not closed and the flow of Potting compound in the gap to the relay should be prevented.
  • the arrangement shown in Figures 1 to 4 comprises a relay 1 and a plug adapter 2, which are connected together.
  • the relay 1 has a housing with a housing cap 11 attached from above and a base plate 12 forming the bottom side of the relay, through which solder pins 13 exit vertically downwards.
  • the bottom side of the relay is sealed with casting resin via a channel or rib system 14.
  • the adapter 2 comprises a base 20 with a base plate 21, on which a circumferential, up and down protruding peripheral wall 22 is formed.
  • the peripheral wall 22 forms a cavity 23 which is open towards the underside and into which a lead frame 24 with a plurality of preformed conductor segments 25 and flat plugs 26 bent downwards is inserted.
  • Each conductor segment 25 has at least one soldering recess 27 for inserting and soldering a connector pin 13 from relay 1 or from an additional component, and each conductor segment 25 is also connected in one piece to a flat plug 26.
  • These flat plugs can have different widths, depending on whether they are required for carrying load current or only for carrying a smaller coil current.
  • the base 20 is first equipped with the one-piece lead frame 24, so that the tabs 26 are pre-fixed to the holding ribs 29 mentioned. This state is shown in FIG. 2 in a perspective view from below. After fixing the individual tabs, the intermediate webs 28 can now be removed. In order to make them accessible for a tool stamp, recesses 32 are provided in the base plate 21.
  • the base is now equipped with the resistors 3 by inserting them into the chambers 30 and inserting their connecting wires into recesses 34 in associated soldering recesses 27.
  • a base equipped in this way is shown in FIG. 3.
  • the relay 1 is now placed on this base from above, the connecting pins 13 being inserted into corresponding soldering recesses 27 in the associated conductor segments. These pins 13 and the lead wires 31 are then soldered with their conductor segments. Then the cavity 23 formed on the underside of the base is filled with potting compound. This potting compound also penetrates into the space between the base plate 12 of the relay and the base.
  • the gap formed between the two is now also sealed by the sealing compound.
  • the chambers 30, which are open at the top, are not or only partially filled with potting compound in this process, since the air cannot escape. This avoids that the resistors 3 are completely embedded and exposed to undesirable voltages. In this way, the arrangement forms a stable new component, as shown in FIG.
  • the tabs in the base in particular are stabilized so that they can also absorb large insertion forces.
  • FIGS 5 and 6 show a slightly modified embodiment.
  • the relay 1 without the housing cap 11 is only equipped with its base plate 12.
  • the housing cap 11 of the relay has an extension downward in the form of a collar 15.
  • the base 40 is formed only by a base plate 41 without a circumferential peripheral wall, namely by overmoulding a lead frame 24, which in this example is designed with preformed conductor segments 25 and flat plugs 26 as in the previous example.
  • This lead frame 24 is thus first encapsulated with plastic during assembly in order to obtain the rimless base 40.
  • the board segments are separated by removing the intermediate webs 28 as in the previous one Example isolated from each other. This state is shown in FIG. 5.
  • the base plate 41 is constructed in exactly the same way as the previously described base plate 21, for example also provided with chambers 30 for receiving the resistors 3.
  • the relay 1 is placed on the base 40 without a cap, and, as before, the connecting pins 13 and the connecting wires 31 are soldered. This state is shown in FIG. 6.
  • the housing cap 11 is now placed over this relay with a base according to FIG. 6, the collar 15 surrounding the base and in turn forming a cavity on its underside which is filled with potting compound.
  • FIG. 7 Another embodiment is shown in FIG. 7.
  • a relay 1 which is closed as in FIG. 1 with a housing cap and a base plate, is connected to an adapter which consists of a base plate (not shown) and a lead frame 44.
  • the base plate is essentially designed in the same way as the base plate 41 in FIG. 5, the lead frame preferably being embedded.
  • the individual conductor segments 45 are preferably separated after embedding, as is also described with reference to FIG. 5. It would also be conceivable to cut and embed the individual parts beforehand.
  • the flat plugs 46 connected to the conductor segments 45 are not bent vertically from the bottom side downwards, but rather vertically from the bottom side upwards along the outer sides of the relay 1.
  • the lead frame 44 is embedded in the material of the base plate, with as little protrusion as possible on the bottom side.
  • resistors 3 or other components are positioned in chambers of the base plate, as in the previous exemplary embodiments, and relay 1 is attached.
  • a frame-shaped sleeve 47 which is only indicated by dashed lines, is now over the tabs on the side of the housing cap 11 are pushed on, and only up to the bottom of the relay.
  • the connecting pins 13 and the connecting wires 31 in the recesses of the conductor segments are easily accessible, so that the soldering can also be carried out by immersion in a solder bath.
  • the sleeve 47 is then moved to a protrusion towards the underside of the adapter, so that the soldered joints lie in a cavity 48 surrounded by the edge of the sleeve.
  • This cavity 48 is now filled with potting compound as in the previous exemplary embodiments.
