Definitions

  • the invention relates to a relay, in particular for automotive engineering, with the features of the preamble of patent claim 1.
  • Known relays for automotive technology which consist of a large number of individual parts, which are usually mounted on a base plate, which at the same time forms the bottom of the relay housing and is used to accommodate connector contacts, but have the disadvantage that for mounting the Large number of individual parts requires a relatively large number of work steps. This applies both to the assembly of the individual parts with one another and to the assembly of the individual parts on the base plate.
  • the implementation of relays with a plurality of switch contacts which can be actuated by a coil is associated with great effort in this technology.
  • the individual work steps are often so complicated that automatic assembly has to be ruled out.
  • manual assembly of the relays has a negative impact on the achievable price-performance ratio.
  • the implementation of relays with a plurality of switch contacts which can be actuated by a coil is associated with great effort in this technology.
  • the relay disclosed in EP 0 283 005 B1 has only one switching contact which is integrated in the coil unit consisting of coil, yoke and armature.
  • the invention has for its object to provide a relay, in particular for the KZF technology, which has a simple structure and can be modified with little effort for different numbers of switching contacts.
  • At least one switching contact the contact spring of which is provided on a stationary supporting part and is connected to the armature by means of a connecting part or a contact spring coupled to the armature
  • at least one switching contact has the advantage that initially all elements of a switching contact, namely at least a fixed contact and a contact spring can be detached from the coil unit, in particular the armature of the coil unit.
  • the design can be adapted to the number of switch contacts required simply by positioning the desired number of switch contacts at suitable locations and connecting the contact springs of all switch contacts to the armature of the coil unit by means of at least one connecting part.
  • connection part must be made of non-conductive material.
  • the connecting part can of course also consist of conductive material.
  • the connecting part is designed to be detachable and / or pluggable, which results in a very simple assembly of the relay.
  • a contact spring of a first switching contact is arranged on the armature in a manner known per se and at least one further switching contact is provided with a contact spring which is arranged on a stationary support part and is connected to the armature or the contact spring of the first switching contact by means of a connecting part .
  • a “basic relay” known per se, which consists of a coil unit and a switch contact which can be actuated by a contact spring provided on the armature of the coil unit, to achieve a modular relay structure.
  • the desired relay can be generated by adding the desired number of switching contacts and connecting the contact springs provided on a fixed supporting part to the armature of the "basic relay".
  • the at least one switching contact is designed as a one-piece contact unit, in which at least one stationary contact and one contact spring provided on a stationary support part are connected by means of a part made of non-conductive material.
  • a contact unit is preferably produced by partially overmolding or potting the electrically conductive contact parts.
  • a coil unit in which a pin made of non-conductive material is guided so as to be axially displaceable, the pin ends or parts connected thereto actuating the armature and the contact spring of a switching contact provided on the side of the coil unit opposite the armature .
  • the coil unit and the at least one switch contact are arranged on a common base plate, which can be designed in a manner known per se as a printed circuit board for contacting the coil unit and the at least one switch contact.
  • Fig. 1 shows a relay 1 according to the invention, which consists of a coil unit 3, which is mounted together with a connector assembly 5 on a carrier part designed as a printed circuit board 7.
  • the coil unit 3 consists of a coil body 9 made of electrically insulating material, which serves to hold the actual relay coil and has a ferromagnetic coil core 13 in the coil axis, and a right-angled yoke 11 made of ferromagnetic material, in one leg of which the coil body 9 with its Coil core 13 is attached.
  • the coil unit 3 has an armature 15 which is mounted in a recess 17 at the end of the leg of the yoke 11 parallel to the coil axis.
  • the armature 15 projects with a partial region 15a beyond the leg of the yoke 11, a pre-tensioned tension spring 19 acting on the partial region 15a, the other end of which is fastened to a fastening arm 21 in the knee of the yoke 11.
  • a contact spring 23 is arranged on the armature 15, at the end of which a cylindrical contact point or contact rivet 25 is provided.
  • the contact spring 23 and thus the armature 15 are supported on a stop 27 of a first contact unit 29.
  • the contact unit 29 can have a single contact 31 which, together with the stop 27, is formed in one piece with the coil former 9.
  • the switching contact designed as a contact unit 29 can, of course, in addition to the arrangement shown as a make contact also be designed as a break contact or changeover contact.
  • the armature 15 is connected by means of a strand 33, the other end of which is inserted into a hole or recess in the printed circuit board 7 and is connected at the rear of the printed circuit board 7 to one of the connection contacts 35 of the plug assembly 5. Since the armature 15 and the contact spring 23 thus serve as current-carrying elements, these must of course consist of electrically conductive material.
  • connection contact 35 of the plug assembly 5 is each connected to a connection contact 35 of the plug assembly 5 by means of printed conductor tracks 39 on the printed circuit board 7.
  • corresponding connection contacts for the wire ends of the coil can be provided in the coil body, so that for the assembly of the coil unit 3, these are only used with the corresponding connection contacts in bores in the printed circuit board 7 and must be soldered to the printed conductor tracks.
  • the yoke 11 can have extensions which engage in holes in the printed circuit board 7 and are soldered to the rear of the printed circuit board.
  • connection contacts 35 which are held in a plate 41 made of non-conductive material.
  • the plate 41 can be made by molding or potting the relevant parts of the contacts 35. All connection ends 35a of the connection contacts 35 are preferably led out on one end face of the plate 41, so that the plug assembly 5 can be assembled in a simple manner by inserting the connection ends 35a into corresponding bores in the printed circuit board 7 and soldering the connection ends to conductor tracks 39.
  • the end face of the plate 41 which releases the connection ends 35a can have a rectangular recess 41a, so that the end face of the plate 41 which is parallel to the upper side of the conductor track serves as a stop and abutment for the relevant circuit board surface.
  • the other leg of the recess 41a also serves as a stop for the end face of the printed circuit board 7 and additionally facilitates the insertion of the connection ends 35a into the corresponding bores in the printed circuit board 7.
  • the relay according to the invention shown in FIGS. 1 and 2 has a further switching contact designed as a contact unit 43 , which is shown in perspective in FIG. 3.
  • the contact unit 43 consists of a fixed contact 45 with a contact point or contact rivet 47, which cooperates with a further contact rivet 49 of a contact spring 51.
  • the switch contact 43 is in turn designed as a make contact.
  • the contact spring 51 is arranged on a stationary support part 53 and can be connected to it in a known manner by means of a rivet 55. To tune the spring characteristics of the contact spring 51, it can also be connected to the support part 53 at a predetermined position by means of a further tuning rivet 57.
  • the contact 45 and the stationary support part 53 can - as shown - be shaped or angled, these being connected by the overmolding of partial areas to form a one-piece unit.
  • the connecting part preferably produced by injection molding 59 can have an arm 59a which, when the contact unit 43 is assembled, comprises the coil body 9 or the first contact unit 29 in a partial region. This results in an exact distance of the contact spring 51 from the contact spring 23 or the armature 15.
  • the contact spring 51 of the further switching contact 43 is connected to the contact spring 23 and thus to the armature 15 of the "basic relay" by means of a connecting part 61 which is preferably made of plastic.
  • the connecting part 61 can - as shown in FIGS. 1 and 3 - have slots 61a and 61b in which the contact springs 23 and 51 are accommodated.
  • the contact spring 23 - as can be seen from FIG. 4 - have an arm 23a, so that it is not the actual contact spring 23 but the arm 23a that is connected to the contact spring 51 of the further switching contact by means of the connecting part 61. Since the arm 23a is connected to the armature 15 by means of an additional rivet 23b, there is the advantage that, due to the complete decoupling of the arm 23a from the actual contact spring, the switching process of the first switching contact 29 is not achieved by coupling the armature or the Contact spring 23 is influenced by the further contact spring 51.
  • the connecting part could also be connected directly to the armature 15 or a separate part attached to it.
  • the addition of additional contact units is preferably carried out on the side of the armature of the coil unit 3, since otherwise a connecting part 61 spanning the entire coil unit 3 would have to be provided, but this would be detrimental to a compact structure of the relay.
  • the core 13 of the relay coil is provided with an axial bore 63, in which a pin 65 made of preferably non-conductive material is axially displaceably guided.
  • the pin 65 acts on the armature 15 at one end and on the other end the contact spring 51 of a contact unit 43 arranged on the side of the coil unit opposite the armature 15.
  • the contact unit 43 can, except for slight deviations in the design of the connecting part 59, as shown 3 be formed. In this way, the switching movement of the armature 15 for actuating a switching contact arranged on the opposite side of the coil unit 3 can be transmitted very easily.
