Description

The present invention is in the field of electrical connectors intended to connect a first plurality of electric cables with a second plurality of electric cables, and to provide an electrical contact, a set of analogous modules, and a connector comprising at least two assemblies. the electric cables being electrically connected in pairs. Such connectors generally have the shape of a housing, a plurality of cables arriving from one side of the housing. The other side of the housing has electrical contacts to be connected to complementary electrical contacts belonging to a second housing. Such connectors are found for example on the roof of a railway vehicle or between two railway vehicles. However, their application is not limited to railways. The invention relates more precisely to an electrical insulator for receiving the electrical contacts. The invention also relates to an assembly comprising said electrical insulator, an outer casing, and the electrical contacts. The invention finally relates to an electrical connector comprising at least two sets.

The electrical contacts extend parallel to each other in a longitudinal direction and are generally aligned in an alignment direction substantially perpendicular to the longitudinal direction. The electrical contacts are sometimes also superimposed in a secondary alignment direction substantially perpendicular to the longitudinal direction and to the alignment direction. Thus, the electrical connectors, and therefore the electrical insulation surrounding the electrical contacts, have shapes and variable dimensions. As a result, the connectors are either parts made "to measure" to meet a particular specification, or are chosen from catalogs offering a wide variety of connectors having predetermined shapes and dimensions. Such profusion of connector designs has a negative impact on the cost of each connector model.

The electrical connector 1 comprises a first set 5 and a second set 10. The electrical connector 1 is shown in FIGS. 1 and 2 in a disconnected configuration in which the first set 5 and the second set 10 face each other in a longitudinal direction L The electrical connector 1 is adapted to connect a first plurality of electric cables 15 electrically connected to the first set 5 to a second plurality of electric cables 20 connected to the second set 10.

The electrical cables 15 are also aligned with each other in an alignment direction II substantially perpendicular to the longitudinal direction L. Similarly, the cables 20 are substantially aligned with each other along the alignment direction 11. As seen in FIG. 3, but also in FIGS. 1 and 2, the first assembly 5 comprises a plurality of modules 25A, 25B, 25C, 25D, electrical contacts 30A, 30B, 30C, 30D received in longitudinal housings 31. through-holes defined by the modules, and four plates 32, 34, 36, 38 fixed to the plurality of modules. The first assembly 5 further comprises sprinklers 40 oriented for example longitudinally and intended to advantageously enhance the strength of the first set. The first assembly 5 finally advantageously comprises polarizing members 42, 44 (Figures 3 and 10) fixed on the plurality 25 of modules. In addition, according to a variant not shown, the first set 5 comprises other elements (not shown) similar to certain elements of the second set 10 which will be described below. The modules 25A, 25B, 25C, 25D are fixed successively on each other and advantageously aligned in the alignment direction II. As the modules 25A to 25D are identical to each other, only the first module 25A will be described in detail with reference to FIGS. 4 and 5. The module 25A comprises a body 46 of general shape, for example parallelepipedal, defining one of the housings 31. extending longitudinally and adapted to receive the electrical contact 30A, and a locking portion 50 forming for example a nut adapted to be screwed into the body 46.

The body 46 and the nut 50 are for example made of plastic material such as polyamide or polycarbonate, and are advantageously obtained by molding. The body 46 comprises for example four lateral faces 52, 54, 56, 58 substantially parallel to the longitudinal direction, a front portion 60 adapted to radially protect an end 62A of the electrical contact 30A received in the module 25A. Throughout the present application, the "forward" direction is defined with reference to the end of the electrical contacts, as opposed to the "back" direction defined with reference to the locking portions 50. The lateral face 52 is for example substantially perpendicular to the alignment direction T1. The lateral face 52 advantageously comprises two fasteners 62, for example in the form of grooves extending in a direction of sliding T2 substantially perpendicular to the longitudinal direction L and substantially perpendicular to the alignment direction T1. The lateral face 52 further comprises a first locking member 64. The lateral face 52 defines two notches 65. The lateral face 54 is opposite to the lateral face 52 in the alignment direction T1. The lateral face 54 comprises two complementary attachment members 66 of the fasteners 62, and a detent member 67 complementary to the detent member 64 located on the lateral face 52. The lateral face 54 defines two notches 68 complementary to the notches 65. The fasteners 66 are adapted to cooperate with the fasteners 62 belonging to the second module 25B to block the second module relative to the first module 25A at least in translation along the alignment direction T1. Advantageously, the fasteners 66 of the first module 25A and the fasteners 62 of the second module 25B form a slide connection in the sliding direction T2. For example, the fasteners 62 comprise a rib with a dovetail section, while the fasteners 66 comprise a complementary groove. For example, the latching member 64 comprises a plate 69 substantially perpendicular to the alignment direction T1 and shaped to be flexible about a substantially longitudinal axis D1. The detent member 64 further comprises a rim 70 shaped hook. The detent member 67 defines a housing 72 adapted to receive the plate 69 in translation in the sliding direction T2, and defines a shoulder 74 adapted to block the flange 70 when the modules 25A, 25B are substantially aligned according to the alignment direction T1. The lateral face 56 is substantially perpendicular to the sliding direction T2. The lateral face 56 has two fasteners 76. The lateral face 58 is opposite the lateral face 56 in the sliding direction T2, and is substantially perpendicular to the sliding direction T2. The lateral face 58 comprises two fasteners 78. The lateral faces 52, 54, 56, 58 comprise recesses defining open boxes 59. The notches 68 of the module 25A are located opposite the notches 65 of the module 25B and define a housing adapted to receive one of the guns 40 longitudinally. The notches 65, 68 have shapes adapted so that the brushes 40 received between the modules 25A and 25B block the module 25B relative to the module 25A at least in translation in a locking direction T3 substantially parallel to the sliding direction T2. The fasteners 76, 78 comprise for example grooves extending in the alignment direction T1. The plates 32, 34, 36, 38 are adapted to surround around the longitudinal direction L the modules 25A, 25B, 25C, 25D assembled together. The plates 32, 34, 36, 38 are for example of substantially rectangular general shape. The plate 32 is substantially perpendicular to the alignment direction T1. The plate 32 comprises two fasteners 80 adapted to cooperate with the fasteners 62 of the module 25A to block the plate 32 relative to the first module 25A at least in translation along the alignment direction T1. The fasteners 80 are for example grooves in which the fasteners 62 can slide in the direction of sliding T2. The plate 34 is opposite the plate 32 in the alignment direction T1 and is substantially perpendicular to the alignment direction T1. The plate 34 comprises two fasteners 82 adapted to cooperate with the fasteners 66 of the module 25D to block the plate 34 relative to the module 25D at least in translation along the alignment direction T1. For example, the fasteners 82 are ribs, advantageously dovetail section adapted to slide in the fasteners 66 in the sliding direction T2.

The plate 36 is substantially perpendicular to the alignment direction T2. The plate 36 comprises two fasteners 84 adapted to cooperate with the fasteners 76 of the modules 25A to 25D to block the plate 36 relative to the module 25A to 25D at least in translation in the sliding direction T2. The plate 38 is substantially perpendicular to the sliding direction T2. The plate 38 comprises two fasteners 86 adapted to cooperate with the fasteners 78 of the modules 25A to 25D to block the plate 38 at least in translation relative to the modules 25A to 25D in the sliding direction T2. The guns 40 comprise a head 90 (FIG. 3) forming a front end in the longitudinal direction L, and a rear end 92 advantageously split in a plane parallel to the longitudinal direction L. The rear end 92 is for example adapted to retain the gollillon 40 between two modules of the plurality 25 in longitudinal translation relative to said plurality 25. The polarizing members 42 are fixed on the front portion 60 of the modules 25A to 25D. The polarizing members 44 (FIG. 10) are fixed, for example by latching, on a rib defined by the body 46 and located close to the locking portion 50 in the longitudinal direction L. The polarizing member 44 is located so as to seen from the rear of the first assembly 5 by a user of the electrical connector 1. Similarly, the polarizing member 42 is located so as to be visible to a user on the front side of the first assembly 5. Referring to FIG. the electrical contact 30A comprises the end 62A, a middle portion 94A, and a clamping element 96A adapted to clamp one of the electric cables 15. In the example shown, the ends 62A to 62D are of the male type. The second set 10 is substantially similar to the first set 5. Also, only the differences will be described in detail below. The second assembly 10 comprises four modules 97A, 97B, 97C, 97D similar to each other and adapted to receive four electrical contacts 98A to 98D complementary electrical contacts 30A to 30D of the first set 5. The second set 10 also comprises two plates 99 , 100 substantially perpendicular to the alignment direction T1 and fixed respectively to the plates 32, 34 of the first set 5. As visible in Figures 1 and 7, the second set 10 further comprises four locking systems 101A to 101D adapted for block the electric cables 20.

The modules 97A to 97D are advantageously analogous to the modules 25A to 25D. The electrical contacts 98A to 98D being similar to each other, only the electrical contact 98A will be described. The electrical contact 98A is received in the housing 31 defined by the module 97A. The electrical contact 98A comprises successively in the longitudinal direction L, a clamping element 105A adapted to clamp one of the electrical cables 20, a middle portion 107A, and an end 109A adapted to receive the end 62A of the electrical contact 30A. In the example shown, the ends 109A to 109D are of the female type. As the locking systems 101A to 101D are similar to each other, only the locking system 101A will be described hereinafter with reference to FIG. 7. The locking system 101A is situated longitudinally behind the second set 10. The blocking 101A comprises a plate 111A for example substantially perpendicular to the longitudinal direction L, a guide member 113A, and a locking member 115A. The wafer 111A is for example of substantially rectangular general shape. The plate 111A is advantageously received in grooves of the plates 36, 38, 99 of the second assembly 10. The guide member 113A surrounds one of the electrical cables 20 around the longitudinal direction L and is adapted to guide the electrical cable 20 and limiting bending movements of the electrical cable 20 tending to separate the electrical cable from the longitudinal direction L. The locking member 115A is movable between an open position shown in FIG. 7, and a closed position adapted to block one electrical cables 20. The locking member 115A is for example rotatably mounted relative to the rest of the locking system 101A about a substantially longitudinal axis D2. The locking member 115A has for example a generally semicircular shape adapted to match the shape of the electric cable 20 in the closed position of the locking member 115A. The mounting and operation of the electrical connector 1 will now be described. To mount the first assembly 5, the electrical contact 30A is inserted into the housing 31 of the module 25A. Then one of the electric cables 15 is inserted longitudinally in the locking portion 50 and in the clamping member 96A. The locking portion 50 is then screwed into the body 46, which tightens the clamping member 96A on the electrical cable 15. The electrical cable 15 is then in electrical contact with the middle portion 94A of the electrical contact 30A, as shown on Figure 1.

The same is done with the other modules 25B to 25D in which are mounted the other electrical cables 15. Then, the modules 25A to 25D are secured to each other. A first solution is to slide the module 25A on the plate 36 (Figure 3) by engaging the fasteners 84 of the plate 36 in the complementary fasteners 76 of the module 25A. Then, the module 25B is fixed on the module 25A by engaging the fasteners 62 located on the module 25B, in the fasteners 66 located on the module 25A. This is achieved by sliding the module 25B with respect to the module 25A in the sliding direction T2. The sliding movement is advantageously interrupted when the module 25A and the module 25B are substantially aligned with each other in the alignment direction T1. This interruption is advantageously achieved by the latching of the detent member 67 located on the lateral face 54 of the module 25A in the complementary detent 64 located on the lateral face 52 of the module 25B. It is then possible to shift the assembly of the modules 25A and 25B by translating them slightly in the alignment direction T1, the fixing members 76 of the module 25B cooperating with the fasteners 84 of the plate 36. The same procedure is carried out to fix the module 25C on the module 25B and to fix the module 25C on the plate 36. Finally, after shifting the assembly of the modules 25A, 25B, 25C relative to the plate 36 in the alignment direction T1, the 25D module is attached to the module 25C and the plate 36 in the same way. As a variant, it is possible first to successively join the modules 25A to 25D successively to each other, then to fix the assembly of the modules 25A to 25D as a single block on the plate 36, by engaging the fasteners 84 of the plate 36 in the aligned fasteners 76 of the modules 25A to 25D. The plates 32 and 34 are then respectively fixed on the modules 25A and 25D by sliding the fasteners 80 of the plate 32 on the fasteners 62 of the module 25A, and the fasteners 82 of the plate 34 on the organs fixing device 66 of the module 25D. Thus, the plates 32, 34 are brought into contact with the plate 36 by a translation of the plates 32, 34 relative to the plate 36 in the sliding direction T2. Finally, the plate 38 is fixed on the modules 25A to 25D by sliding the fasteners 86 of the plate 38 in the aligned fasteners 78 of the modules 25A to 25D according to the alignment direction T1.

To improve the strength of the assembly thus formed, the brushes 40 are inserted longitudinally in the recesses formed by the notches 65, 68 defined by the modules 25A to 25D. The first assembly 5 shown in FIG. 1 is thus obtained. The second assembly 10 is similarly carried out, except that, at the insertion step of the electrical cable 20 into the module 97A, the electrical cable is first inserted in the locking system 101A, then in the locking portion 50 and in the clamping member 105A. When the modules 97A to 97D are slid on the plate 36 of the second assembly 10, the plates 111A of the locking systems 101A are further received in a groove of the plate 36. The locking members 115A are closed again on the electrical cables 20 and screwed on the rest of the locking systems 101A to 101D. As can be seen in FIGS. 1 and 2, the first assembly 5 and the second assembly 10 are advantageously fixed on one another by fixing the plates 99, 100 of the second assembly 10 on the plates 32, 34 of the first assembly 5. In addition, each of the first set 5 and the second set 10 is advantageously fixed on a support, for example the roof of a railway vehicle (not shown). The rest of the operation of the electrical connector 1 is deduced from its structure. By the assembly described above, each electrical cable 15 is in electrical contact with one of the ends 62A to 62D of the electrical contacts 30A to 30D. The modules 25A to 25D form an insulating block around the contacts 30A to 30D. The insulating block is further protected by the housing formed by the plates 32, 34, 36, 38. The same applies to the second assembly 10. The electrical cables 20 are in electrical contact with the ends 109A of the contacts 98A to 98D . In addition, the optional locking systems 104A to 104D improve the blocking of the electrical cables 20 in the longitudinal direction L with respect to the second set 10. To connect the first set 5 with the second set 10, the first set and the second set are brought closer to each other in the longitudinal direction L, the electrical contacts 30A to 30D being located vis-à-vis the electrical contacts 98A to 98D. Each male end 62A-62D is received in the corresponding female end 109A-109D. Once the contact established between the electric cables 15 and the electrical cables 20, the second assembly 10 is fixed on the first assembly 5. Advantageously, the first assembly 5 and the second assembly 10 are also fixed on a support (not shown ). Thanks to the characteristics described above, in particular the modules 25A to 25D, a modular insulating body is obtained, adapted to the number of contacts to be made, which is four in the example shown. The first assembly 5 and the second assembly 10 thus formed offer a reduced cost. The first assembly 5 and the second assembly 10 are furthermore easy to assemble or disassemble. The modules 25A to 25D and 98A to 98D are reusable to constitute other similar assemblies to the first set 5, but for example comprising a different number of electrical contacts. The polarizing members 42, 44 make it possible to avoid poor connections between the electric cables 15, 20 and the electrical contacts 30A to 30D and 98A to 98D, on the one hand, and between the electrical contacts themselves, on the other hand . With reference to FIGS. 8 and 9, an electrical connector 200 constituting a second embodiment of the invention will now be described. The electrical connector 200 is similar to the electrical connector 1. Also, the electrical connector 200 will not be described in detail. The electrical connector 200 differs from the electrical connector 1 shown in Figures 1 to 7 by the following features. The electrical connector 200 comprises a first assembly 205, and a second assembly 210 electrically connected to the first assembly. The first set 205 comprises two modules 25A, 25B fixed to one another, and three plates 32, 34, 38 fixed to the modules 25A, 25B. The first set 205 further comprises two electrical contacts 230A, 230B bent "U". The second assembly 210 comprises two similar modules 97A, 97B located respectively under the modules 25A, 25B in the sliding direction T2. The electrical contacts 230A, 230B are adapted to electrically connect respectively the electrical contact 30A with the electrical contact 98A, and the electrical contact 30B with the electrical contact 98B. The second assembly 210 is adapted to be plugged into the first assembly 205 in the longitudinal direction L. The modules 97A, 97B are further respectively fixed on the modules 25A, 25B by cooperation of the fasteners 78 located on the modules 97A, 97B with the fasteners 76 located on the modules 25A, 25B.
