Definitions

  • the invention is aimed at an electric connector of the type specified in the introductory part of Claim 1.
  • This connector consists of a coupling part each exhibiting a housing and of an opposite coupling part.
  • the housing of the coupling part possesses a receptacle for plugging in the housing belonging to the opposite coupling part, for which reason in what follows the first housing is to be designated the "receptacle housing” for short and the second housing as the "plug-in housing".
  • Both housings possess contact parts or opposite contact parts connected to electric leads which in the connected state are in engagement with one another. Between the two housings is located an annular seal which in the event of connection locks the interlocking contact parts in watertight manner in the housings which have been plugged into one another.
  • a sealing ring is pushed loosely on to the radial circumferential surface of the plug-in housing and in the connected state works together in sealing manner with the radial inner surface of the receptacle housing.
  • the two housings of the coupling part and the opposite coupling part with the sealing ring are supplied by the manufacturer to be equipped in each case by the vehicle manufacturer with two sets of cables manufactured elsewhere on which are seated on the one hand the contact parts and on the other hand the opposite contact parts. In doing so the loose ring seal can go astray. Pushing the seal on to the plug-in housing is a relatively time-consuming process. In the harsh conditions of the assembly plant of the vehicle manufacturer inaccuracies in the position of the seal can result, in particular when the two housings have to be fitted through an opening on both sides of a wall of the bodywork.
  • the object underlying the invention is to develop a reliably sealed connection of the type mentioned in the introductory part of Claim 1 which can be quickly and conveniently assembled from its components and if required fitted on a wall. This is achieved according to the invention by means of the measures specified in the characterising part of Claim 1, to which the following special significance attaches.
  • the seal is first preassembled with a carrier and forms a constructional unit which in the following shall be designated as the "seal carrier" for short.
  • This seal carrier is fixed in the interior of the receptacle housing and therefore from the outset assumes a defined position there. Because the seal is a fixed component of the carrier seated in the interior of the receptacle housing, it can be preassembled at the place of manufacture and no longer go astray in the performance of the further fitting tasks for the coupling part and opposite coupling part.
  • two parts capable of being coupled to one another are provided which consist of a coupling part 10 and an opposite coupling part 20 which are shown in Figure 5 in the finally coupled state.
  • the two parts 10, 20 comprise two housings 11, 21, the special construction of which can be seen in Figure 1.
  • the housing 11 comprises a receptacle 12 which is destined for the plug-in reception of a housing core 22 of the other housing 21.
  • one housing 11 is to be designated as "receptacle housing” and the other housing 21 correspondingly as "plug-in housing".
  • Both housings 11, 21 possess numerous chambers 13 and 23 respectively, in which on the one hand contact parts 14 and on the other hand opposite contact parts 24 can be fixed by means of inherently known, and if necessary lockable, catches.
  • the contact parts 14 consist of plugs which are connected to a set of leads 15.
  • the opposite contact parts 24 are designed as complementary sockets which are connected to further electric leads 25.
  • the electric connection comprises as a further component a constructional unit 30 which for its part is preassembled from the two components discernible in Figure 2, that is an annular seal 31 and a carrier 32 accommodating the seal.
  • this constructional unit which can be seen in the assembled state in Figure 1, shall be called the "seal carrier" for short.
  • This seal carrier 30 has the following construction.
  • the carrier 32 is shaped like a ring and at its inner end 33 comprises a sleeve 34 which serves as a holding device for the seal 31.
  • the seal 31 has a U-shaped cross section and is divided into a U-crosspiece 37 with two legs 35, 36 of the U proceeding from it. Between these is located a U-groove 38 in which, as can be seen in Figure 1, the sleeve engages in the preassembly of the seal carrier 30, the U-crosspiece 37 covering the front end 39 of the sleeve 34.
  • the assembled state can also be seen from the detailed view of Figure 4 where the two legs 35, 36 of the U each produce a sealing layer on the inner and outer sides 45, 46 of the sleeve 34 facing away from one another.
  • the modular seal carrier 30 is plugged initially in the direction of the arrow 40 of Figure 1 in the receptacle 12 of the receptacle housing and there fixed by means of snap-in elements 41, 42 according to Figure 3.
  • the carrier 32 possesses a tube 43 constructed here in double-walled fashion, on the outer casing surface 44 of which is seated a tooth 41 functioning as a snap-in element. In the assembled state the latter engages from the radial inner surface 16 of the receptacle housing 11 into an opening 42 provided there which forms the opposing snap-in element 42.
  • the sealing ring is provided on its outwardly facing circumferential surface with sealing lips 47, of which that of the leg 36 of the U comes to fit in effective sealing manner against the aforementioned radial inner surface 16 in the receptacle housing 11.
  • the sealing lips 47 located on the U-crosspiece 37 are supported against an axial shoulder 17 in the interior of the receptacle housing 11 which is here formed by the bottom of the housing.
  • complementary profiles are provided in their outer contour region. This purpose is served by a conical perimeter channel 48 in the base region of the sleeve 34 into which the inner leg 35 of the U of the seal 31 engages with a corresponding conical end profile.
  • the receptacle housing 11 with the seal carrier 30 seated therein through the snap-in connection 41, 42 is supplied by the manufacturer. This subassembly is then equipped at another location with a set of cables as can be seen in Figure 3 with reference to a single contact part 14 connected to a lead 15.
  • the original receptacle 12 of the housing 11 is encased by the aforementioned double-walled tube 43 and the interior 49 of the tube is available for accommodating the plug-in housing 21.
  • the finished coupled state is illustrated in Figure 5.
  • the core 22 of the housing of the opposite coupling part 20 is introduced into the interior 49 of the tube by means of a simple plug-in movement in the direction of the arrow 50 of Figure 1.
  • the plug-in housing 21 possesses an outer shell 27 which in the connected state of Figure 5 covers the circumference of the receptacle housing 11.
  • the receptacle housing 11 On its circumferential surface 19 the receptacle housing 11 possesses a retaining hook 18 pointing radially outwards which in this embodiment of the electric connection ensures cohesion of the two coupling parts 10, 20.
  • FIGs 6 to 8 show a practical construction of the electric connector which is designed according to the principle of construction of Figures 1 to 5 described previously. For that reason the same reference symbols are used to label corresponding component parts. To that extent the description so far is valid. It is sufficient merely to go into the details of the differences.
  • the two coupling parts 10, 20 are fitted on both sides of a wall 60, indicated there by dotted lines, which is a wall of the body which separates the engine compartment 52 of a motor vehicle from the passenger compartment 51.
  • the wall 60 has an opening 63 which, as emerges from Figure 7, is penetrated by the coupling part 10.
  • Its receptacle housing 11 is fitted from the side 61 of the wall 60 facing towards the passenger compartment 51 by simply plugging it in. In doing so the previously described retaining hooks 18 of the receptacle housing snap around the edge of the opening 63 beaded with respect to the engine compartment 52.
  • the receptacle housing 11 is already fastened in a preassembly position to the wall 60 and on the opposite side 62 projects out with its housing end 53 on the opposite side 62 of the wall.
  • the receptacle housing 11 possesses a flange 54 on which an annular sealing means 55 rests. The latter is supported in the assembled state against one side 61 of the wall.
  • the structure of the coupling part 10 can be seen in the plan view shown in Figure 6.
  • Three retaining hooks 18 are provided which project radially outwards with each of their hook ends in a recess of the outer wall of the tube wall 43 and engage according to Figure 7 behind the beaded rim 63 of the opening.
  • the retaining hooks 18 are arranged in an open space of the outer tube wall 43 of the carrier.
  • a protective cap 56 temporarily covers the interior of the receptacle housing 11 and thereby also protects the previously described contact parts seated there which are seated at the end of the electric leads 15 drawn only by dotted lines in Figure 7.
  • This protective cap 56 is connected to the receptacle housing 11 by means of catch elements, of which only one catch element 57 is visible in Figure 8. There of course the protective cap 56 has already been removed again.
  • This catch element 57 consists of a recess, which is located in the preassembled seal carrier 30, that is as an opening in the inner tube wall 43 of the carrier 31.
  • the opposing catch element which is not shown in further detail, is seated on a tubular lug 58 engaging in the tube interior 49 and consists of a projection pointing radially outwards.
  • FIG 8 shows the coupled state of both parts 10, 20.
  • the plug-in housing 21 of the opposite coupling part 20 grips round the already preassembled subassembly, provided from the coupling part 10 with the seal carrier 30 integrated therein, with an outer shell 27.
  • the outer shell 27 covers the previously described projecting end 53 of the housing and after the coupling has been carried to completion comes to lie with its shell front edge 28 against the side 62 of the wall facing towards the engine compartment 52.
  • the two housings 11, 21 are pushed against one another by means of a central screw 29. In doing so a definite compression of the previously described sealing means 55 results.
  • the housing flange 54 carrying the sealing means 55 possesses a circumferential axial rib 59 with a defined rib height 69.
  • This rib height 69 is of such a size that when the two housings 11, 21 are pressed together, the sealing means 55 is compressed to this extent. That is to say the front edge 68 of the flange rib 59 is supported against the side 61 of the wall, while the front edge 28 of the outer shell 27 belonging to the opposite coupling part 20 is pushed against the opposite side 62 of the wall.
  • a further special feature consists in that the seal carrier 30 fitted in the receptacle housing 11 also serves to secure the position of the sealing means 55 provided on the flange 54. That is, for this purpose the outer wall of the double-walled tube 43 possesses radial projections 64 which always secure the proper position of the sealing means 55 on the flange 54. Therefore when handling the coupling part 10 during its assembly on the wall 60 this sealing means 55 is also secured.
  • the carrier 32 has to fulfil a double function; it secures not only the inner seal 31 which it introduces but also the outer sealing means 55. Therefore during assembly of the coupling part 10 these components too can no longer go astray.
  • Both housings 11, 21 are in themselves composed of several housing elements. Located between the housing elements is a so-called locking slide 67 which locks the fitted contact parts 14 and opposite contact parts 24 in the two housings 11 and 21 respectively, after these have previously been plugged into the chambers 13, 33 axially and latched by means of tongues.
