Definitions
- the invention is aimed at an electric connector of the type specified in the introductory part of Claim 1.
- Such an electric connector is described in documents US-A-5 545 048 and EP-A-0 537 751.
- This connector consists of a coupling part and of an opposite coupling part each exhibiting a housing.
- 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.

Description
- The invention is aimed at an electric connector of the type specified in the introductory part of Claim 1. Such an electric connector is described in documents US-A-5 545 048 and EP-A-0 537 751. This connector consists of a coupling part and of an opposite coupling part each exhibiting a housing. 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.
- In a known connector, 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. When used in motor vehicle construction, 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.
- In the invention 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. In doing so it is especially advantageous not to provide the seal on the carrier in the outer region of the partition joint between the two housing parts but rather at the inner end in the base region of the annular gap between the radial circumferential surface of the plug-in housing and the radial inner surface of the receptacle housing.
- The present invention will now be described, by way of example, with reference to the accompanying drawings, in which:-
- Figure 1 shows the principle of construction of the electric connector according to the invention with its various parts in exploded illustration and in longitudinal section, to which a specially preassembled constructional unit, namely the aforementioned seal carrier, belongs;
- Figure 2 shows the two components of the seal carrier of Figure 1 in a further exploded illustration and in longitudinal section;
- Figure 3 shows the assembled components of one coupling part of the connection according to the invention in enlargement and in longitudinal section;
- Figure 4 shows the detail labelled with IV in Figure 3 in a further enlargement;
- Figure 5 shows the coupling part of Figure 3 in a representation corresponding to Figure 1 but enlarged, in the state of connection to an opposite coupling part, assembled from further components, of the connector according to the invention;
- Figure 6 shows in plan view a practical design of a coupling part of the connector according to the invention used for vehicle electrification, the housing of which is to be fitted in the region of an opening on one side of a body wall of a motor vehicle;
- Figure 7 shows a longitudinal section through the coupling part of Figure 6 along the dashed section line VII-VII there, where the position of the wall for fitting the coupling part is indicated by dotted lines and the housing, supplementary to Figure 6, is covered temporarily with a protective cap; and
- Figure 8 shows both the latter coupling part as well as the opposite coupling part connected thereto on the body wall of the motor vehicle likewise indicated by dotted lines, in a sectional view analogous to Figure 7 but along the further dashed section line VIII-VIII shown in Figure 6.
-
- As shown in the construction in principle of the electric connector according to the invention shown in Figures 1 to 5, two parts capable of being coupled to one another are provided which consist of a
coupling part 10 and anopposite coupling part 20 which are shown in Figure 5 in the finally coupled state. As shown in Figure 1, the twoparts housings housing 11 comprises areceptacle 12 which is destined for the plug-in reception of ahousing core 22 of theother housing 21. For this reason, as has already been explained at the outset, onehousing 11 is to be designated as "receptacle housing" and theother housing 21 correspondingly as "plug-in housing". - Both
housings numerous chambers hand contact parts 14 and on the other handopposite contact parts 24 can be fixed by means of inherently known, and if necessary lockable, catches. In the present case thecontact parts 14 consist of plugs which are connected to a set ofleads 15. For that reason theopposite contact parts 24 are designed as complementary sockets which are connected to furtherelectric leads 25. - As can best be observed in Figure 1, 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 anannular seal 31 and acarrier 32 accommodating the seal. In what follows this constructional unit, which can be seen in the assembled state in Figure 1, shall be called the "seal carrier" for short. Thisseal carrier 30 has the following construction. - As can best be seen in Figure 2, the
carrier 32 is shaped like a ring and at its inner end 33 comprises asleeve 34 which serves as a holding device for theseal 31. For this purpose theseal 31 has a U-shaped cross section and is divided into aU-crosspiece 37 with twolegs seal carrier 30, the U-crosspiece 37 covering thefront end 39 of thesleeve 34. The assembled state can also be seen from the detailed view of Figure 4 where the twolegs outer sides sleeve 34 facing away from one another. Themodular seal carrier 30 is plugged initially in the direction of thearrow 40 of Figure 1 in thereceptacle 12 of the receptacle housing and there fixed by means of snap-inelements carrier 32 possesses atube 43 constructed here in double-walled fashion, on theouter casing surface 44 of which is seated atooth 41 functioning as a snap-in element. In the assembled state the latter engages from the radialinner surface 16 of thereceptacle housing 11 into anopening 42 provided there which forms the opposing snap-inelement 42. - As emerges from Figure 4, the sealing ring is provided on its outwardly facing circumferential surface with sealing
lips 47, of which that of theleg 36 of the U comes to fit in effective sealing manner against the aforementioned radialinner surface 16 in thereceptacle housing 11. The sealinglips 47 located on the U-crosspiece 37 are supported against anaxial shoulder 17 in the interior of thereceptacle housing 11 which is here formed by the bottom of the housing. For securing the position of theseal 31 on thecarrier 32 complementary profiles are provided in their outer contour region. This purpose is served by aconical perimeter channel 48 in the base region of thesleeve 34 into which theinner leg 35 of the U of theseal 31 engages with a corresponding conical end profile. By this means any pushing of the seal away during the subsequent connection of theopposite coupling part 20 is prevented. Further contour profiles, which are not illustrated, between thesleeve 34 and the inner surfaces of the U-groove 38, such as cams and recesses, can be used for additional axial cohesion of the twostructural parts constructional unit 30. - The receptacle housing 11 with the
seal carrier 30 seated therein through the snap-inconnection single contact part 14 connected to alead 15. Theoriginal receptacle 12 of thehousing 11 is encased by the aforementioned double-walled tube 43 and theinterior 49 of the tube is available for accommodating the plug-inhousing 21. - The finished coupled state is illustrated in Figure 5. After the
further leads 25 already mentioned together with theiropposite contact parts 24 have been fitted in the plug-inhousing 21, thecore 22 of the housing of theopposite coupling part 20 is introduced into theinterior 49 of the tube by means of a simple plug-in movement in the direction of thearrow 50 of Figure 1. The plug-inhousing 21 possesses anouter shell 27 which in the connected state of Figure 5 covers the circumference of thereceptacle housing 11. On itscircumferential surface 19 thereceptacle housing 11 possesses aretaining hook 18 pointing radially outwards which in this embodiment of the electric connection ensures cohesion of the twocoupling parts inner leg 35 of the U of theseal 31 is supported against the radialcircumferential surface 26 by thecore 22 of the housing of the plug-inhousing 21. On disconnecting theopposite coupling part 20 from thecoupling part 10 in the direction of the arrow 50' of Figure 5 theseal carrier 30 remains behind in thereceptacle housing 11 on account of theelements - Figures 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.
- As emerges from Figure 8, the two
coupling parts wall 60, indicated there by dotted lines, which is a wall of the body which separates theengine compartment 52 of a motor vehicle from thepassenger compartment 51. Thewall 60 has anopening 63 which, as emerges from Figure 7, is penetrated by thecoupling part 10. Itsreceptacle housing 11 is fitted from theside 61 of thewall 60 facing towards thepassenger compartment 51 by simply plugging it in. In doing so the previously described retaininghooks 18 of the receptacle housing snap around the edge of theopening 63 beaded with respect to theengine compartment 52. By this means thereceptacle housing 11 is already fastened in a preassembly position to thewall 60 and on theopposite side 62 projects out with itshousing end 53 on theopposite side 62 of the wall. Thereceptacle housing 11 possesses aflange 54 on which an annular sealing means 55 rests. The latter is supported in the assembled state against oneside 61 of the wall. - The structure of the
coupling part 10 can be seen in the plan view shown in Figure 6. The upper front end of thetube 43 of theseal carrier 30, which is double-walled in regions and drawn in dotted lines, is seen. Three retaining hooks 18 are provided which project radially outwards with each of their hook ends in a recess of the outer wall of thetube wall 43 and engage according to Figure 7 behind thebeaded rim 63 of the opening. The retaining hooks 18 are arranged in an open space of theouter tube wall 43 of the carrier. During assembly of the coupling part 10 aprotective cap 56 temporarily covers the interior of thereceptacle 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. Thisprotective cap 56 is connected to thereceptacle housing 11 by means of catch elements, of which only onecatch element 57 is visible in Figure 8. There of course theprotective cap 56 has already been removed again. Thiscatch element 57 consists of a recess, which is located in thepreassembled seal carrier 30, that is as an opening in theinner tube wall 43 of thecarrier 31. The opposing catch element, which is not shown in further detail, is seated on atubular lug 58 engaging in thetube interior 49 and consists of a projection pointing radially outwards. After the described preassembly of thecoupling part 10 on thewall 60, on account of the elastic connection through thecatch elements 57 theprotective cap 56 can be pulled off before theopposite coupling part 20 is plugged in axially. - Figure 8 shows the coupled state of both
parts housing 21 of theopposite coupling part 20 grips round the already preassembled subassembly, provided from thecoupling part 10 with theseal carrier 30 integrated therein, with anouter shell 27. Theouter shell 27 covers the previously described projectingend 53 of the housing and after the coupling has been carried to completion comes to lie with itsshell front edge 28 against theside 62 of the wall facing towards theengine compartment 52. The twohousings central screw 29. In doing so a definite compression of the previously described sealing means 55 results. - For this purpose the
housing flange 54 carrying the sealing means 55 possesses a circumferentialaxial rib 59 with a defined rib height 69. This rib height 69 is of such a size that when the twohousings front edge 68 of theflange rib 59 is supported against theside 61 of the wall, while thefront edge 28 of theouter shell 27 belonging to theopposite coupling part 20 is pushed against theopposite side 62 of the wall. - As emerges from Figure 7, a further special feature consists in that the
seal carrier 30 fitted in thereceptacle housing 11 also serves to secure the position of the sealing means 55 provided on theflange 54. That is, for this purpose the outer wall of the double-walled tube 43 possessesradial projections 64 which always secure the proper position of the sealing means 55 on theflange 54. Therefore when handling thecoupling part 10 during its assembly on thewall 60 this sealing means 55 is also secured. Thus in the assembled state on the receptacle housing, thecarrier 32 has to fulfil a double function; it secures not only theinner seal 31 which it introduces but also the outer sealing means 55. Therefore during assembly of thecoupling part 10 these components too can no longer go astray. - The electric leads 15, 25 belonging to the contact and
opposite contact parts end cap screw 29. Bothhousings locking slide 67 which locks the fittedcontact parts 14 andopposite contact parts 24 in the twohousings chambers 13, 33 axially and latched by means of tongues.
