Definitions

  • the invention relates to the arrangement of a relay on a Plug-in base, the relay being a housing made of dimensionally stable Has material with pins sticking out of the bottom, and wherein the socket is a housing also dimensionally stable material with the top open Has plug pins of the relay receiving plug openings.
  • a so-called relay is also used Relay module understood, in addition to in the housing the actual relay system further circuit elements, such as Resistors and diodes with the associated conductor tracks are.
  • sealing relay housings There are many options for sealing relay housings have already been described, for example the shedding of Housing gaps with liquid and subsequently curable Sealing compound. It is also known (DE 43 37 505 C1), wall areas between base or base plate on the one hand and cap on the other hand, in a two-component spraying process with a Cover the elastomer layer and so when pressed together the housing parts to achieve the desired seal.
  • the aim of the present invention is to provide a simple seal between a pluggable relay and the associated one To create plug-in bases that have only minor design changes required and with plug-in assembly without additional Individual parts, such as sealing rings and the like, get by.
  • this goal is achieved in that at least one of the two housings made of a dimensionally stable, thermoplastic material and one in the other Housing facing, the plug pins and plug openings enclosing Edge zone a one-piece molded sealing ring made of elastomer and that the two housings by means of overlapping Wall elements under elastic deformation the sealing ring is positively and / or non-positively connected are.
  • the housing caps of such relays and also the housing of jacks usually made of thermoplastic anyway dimensionally stable plastic can be produced the additional molding of a thermoplastic, elastomer Sealing rings in the two-component spraying process only a small one additional manufacturing effort.
  • the sealing ring can either be molded onto the relay cap and its lower one Form edge, or it can be opposite the edge of the relay cap recessed into the flat top of the socket be. But it can also be used as a radial seal in the overlap area between socket and relay cap on the be molded on one part or the other.
  • FIG 1 the arrangement of a relay 1 on a plug base 2 shown.
  • the relay has a housing with a Housing cap 11 and a base plate 12, in which connector pins 13 are anchored. These connector pins are flat tabs trained, as can be seen in Figure 3.
  • the plug-in base 2 has a housing 21 with chambers 22, in which sockets 23 are arranged.
  • the chambers 22 open out to the top of the housing 22 in plug openings 24, through which the connector pins 13 of the relay are inserted.
  • On lead wires 25 are led out from the underside of the housing 21, which inside with not shown the sockets 23 are connected.
  • a web-shaped sealing ring 14 is formed.
  • This sealing ring 14 consists of an elastomeric thermoplastic, while the housing cap 11 otherwise from a dimensionally stable thermoplastic. In this way it is possible the housing cap in a two-component spraying process with the sealing ring in one piece.
  • the housing cap is also provided with locking lugs 15 which engage in retaining tabs 26 of the socket. As in figure 1 can be seen, the locking ring turns the sealing ring 14 elastically deformed, which creates the desired seal of the two housings.
  • FIGS. 4 and 5 A modified embodiment is shown in FIGS. 4 and 5 shown.
  • the structure of relay 1 and socket 2 is largely the same as in Figure 1.
  • the sealing is done but here in a complementary way.
  • the sealing ring 14 on the relay cap is now a sealing ring 27 in the injected flat top of the plug-in housing 21 deepened.
  • FIGS. 6 and 7 A further modification is shown in FIGS. 6 and 7.
  • the relay cap 11 engages with a molded-on downward Collar 17 over the base housing 21, which one radial sealing ring 28 carries, all the way into a recess the side wall is injected.
  • the elastic deformation of the sealing ring 28 results from the non-positive Push the collar 17 onto the base housing 21.
  • each Ring seals 29 are provided in the base housing 21.
  • This Ring seals 21 can be made in the same way as the radial ones Sealing rings 28 in one piece in a two-component spraying process be molded onto the base housing 21.
  • FIG 8 is a top view of a modified Socket housing 31 shown, which also like that in Figure 7 shown rectangular housing with a radial seal, in this case can be provided with a sealing ring 38.
  • This Plug housing would be suitable for a relay, which also had a correspondingly round cross-section.
  • FIG. 9 shows a further modification of a relay socket arrangement shown similar to Figure 6.
  • a sealing ring 18 provided, which in turn made of elastomeric material in one piece in two-component injection molding with the relay cap 11 is connected.
  • the sealing ring 18 like it is shown in FIG. 9 on the left side of the cap 11, can also be a sealing ring 19 as shown on the right Page of Figure 9 can be used.
  • This also applies roof-shaped over the upper edge of the collar 30 and prevented so that water or dirt gets into the gap between the relay housing cap 11 and base collar 30 can settle. Otherwise, both relay 1 and socket 2 are as constructed in the other examples.
