Definitions
- the invention relates to a relay with a coupling element, according to the preamble of claim 1.
- a relay with a coupling element there is a need to double or triple the relay functions in order to make a "single" from a "twin” or “triplet”
- Such a need exists above all in safety technology, where it is important that in the event of a fault, for example when contacts are merging or blocking, there are still parallel contacts which take over the switching function.
- Another need is to accommodate a large number of relay contacts with as little wiring as possible in the smallest possible space.
- the contact springs should be directly electrically connected to one another.
- the invention is therefore based on the object of developing a relay of the type mentioned in such a way that it can be formed into a relay twin or a relay triplet without circuitry.
- the relay is characterized by the technical teaching of claim 1.
- a coupling element is provided which mechanically couples several spring brackets to one another.
- a single relay can quickly via the connection medium of a coupling element to a multiple relay, for. B. a relay twin or a relay triplet.
- the fast, mechanical connection by means of a coupling element is therefore claimed as an essential feature of the present invention.
- the coupling element also carries the electrical through connection between the spring brackets in itself, so that an external connection effort (e.g. via a circuit board on which the relays are seated with their connecting pins) is avoided. and that with the help of the mechanical coupling of the
- Coupling element at the same time the electrical coupling of the spring bracket to be connected is produced.
- the electrical connection of the interconnecting spring brackets takes place via the passive contact springs.
- individual passive contact springs are no longer assigned to the respective spring block, but that one of the two spring blocks is assigned a double contact spring which consists of two individual contact springs which are connected to one another by means of an electrically conductive connecting web.
- active and passive contact springs must not be interpreted as restricting intellectual property rights. Rather, it is within the scope of the invention, instead of the passive contact springs described here, to connect the active contact springs in an electrically conductive manner by means of a contact element via a coupling element in that the respective associated contact spring is arranged on one side of the coupling element and the electrically conductive connection between this contact springs is brought about by a connecting web which passes through the coupling element and is fastened to it.
- the coupling of the coupling element is designed to be latching and releasable again with the spring brackets to be connected.
- the coupling of the coupling element with the spring brackets is fixed. It can be used here, for example, an adhesive, sweat or other fluid connection.
- a particularly compact design results when the active and passive contact springs are arranged at an angle of 90 °.
- the coupling element consists of an insulating material and has at least one partition wall running parallel to the contact rows of the relay, on which lateral projections are formed, which engage in assigned receiving openings on the respective spring bracket.
- Grooves which are suitable for receiving the contact springs are formed between the lateral approaches of the partition. After, on the other hand, slots are opened parallel to the longitudinal axes of the receiving openings in the respective spring bracket towards the end face, the passive contact springs can be inserted there.
- FIG. 1 Schematic of a single relay
- FIG. 1 Schematic of the coupling of two individual relays with one
- Coupling element Figure 3 The assembled state of a relay twin Figure 4: An exploded view compared to Figure 3 showing different contact springs
- the single relay consists of a spring bracket 1 on which the drive 5 is arranged.
- An active contact spring 2 which is actuated by an actuator 4, is arranged lying on the spring bracket 1.
- a passive contact spring 3 is arranged standing in the spring bracket. All contact sets are arranged in a contact row 25, the contact sets being separated from one another by associated partition walls 12.
- connection pins 6 which are led out downwards, just as the active and passive contact springs 2, 3 are led out downwards by assigned connection pins 7.
- the one end face of the spring bracket 1 has receiving openings 8 which are open at the end and which are intended for the engagement of associated projections 16 of a coupling element 14. Slits 9 are formed between the receiving openings 8, into which the passive contact springs 3 are inserted from the end face and are held there. The mounting is carried out by multiple cranked grooves 10, so that a cheap, stable mounting of the respective contact spring 3 is guaranteed.
- the coupling element 14 is provided, which essentially consists of a plastic part which has a central partition wall 15, the height of which corresponds approximately to the height of the spring bracket 1, 13.
- the lugs 16, which are intended to engage in the associated receiving openings 8 of the spring brackets 1, 13, extend from the partition wall 12 in opposite directions.
- the partition wall 15 forms an approximately T-shaped shape in the lower region with a cross member 20 formed on the partition wall 15, on the underside of which support ribs 17 are arranged.
- a favorable, rigid mechanical connection between the spring brackets 1, 13 to be connected is achieved, because, as shown in FIG. 3, the cross member 20 engages in an associated, one-sided, open snap-in receptacle 19 and is fixed there with assigned snap-in means 18.
- a fluid connection of the coupling element to the respective spring bracket 1, 13 can be achieved in that the touching and interlocking parts are glued with adhesive.
- Spacer ribs 24 are also arranged laterally on the partition wall 15 and are spaced apart for the associated end faces of the receiving openings 8. The end faces of the receiving openings 8 of the respective spring brackets 1, 13 therefore rest on these spacer ribs 24.
- a double contact spring 21 is provided, as shown in FIG. 4. It consists of the aforementioned passive contact springs 3, which are connected to one another by means of an electrically conductive connecting web 22.
- the right spring bracket 1 is now pushed in the arrow direction 27 against the coupling element 14, so that the right contact spring 3 is inserted into the slot 9 on the spring bracket 1 and at the same time the lugs 16 engage in the receiving openings 8 on the spring bracket.
- connection to the opposite spring bracket 13 takes place in an analogous manner.
