Definitions

  • the invention relates to an electrical connector for connecting cables ensuring the electrical power connection between two adjacent cars of a railway vehicle.
  • each cable can only pass a limited power. So, twenty connecting cables between each car may be necessary for vehicles with distributed motorization.
  • Such a multiplication of connecting cables presents however the disadvantage of multiplying the number of connectors arranged in each vehicle to establish the connection between these connecting cables and a circuit vehicle.
  • the space available to install these connectors is limited due to the presence of the traffic lane between vehicles.
  • the object of the present invention is to provide an electrical connector for the connection of a cable ensuring the electrical connection between two cars of a light, space-saving rail vehicle that requires no tools for connecting the link while being simple and economical to make.
  • a another object of the present invention is to provide an electrical connector which allows connection of connection cables without risk of incorrect connection.
  • the invention relates to an electrical connector for connection a connection cable ensuring the electrical connection between two cars in a vehicle railway, characterized in that it comprises a base of electrically material insulation on which rests a profile of electrically conductive material, the profile being connected to an electrical circuit of the car to be connected and supporting at least one socket intended to receive a pin arranged at one end of the connecting cable.
  • Figures 1 to 3 show a connection module comprising a connector 1 intended to be placed in a railway vehicle car, preferably at near a longitudinal end of the car.
  • This link module is intended to allow the connection of an electrical circuit 6 of the car with a cable 2 providing the electrical connection to a second car of the railway vehicle.
  • the connector 1 comprises a base 3 made of material electrically insulating, such as Latamid, comprising two side walls rising on either side of a central staircase-shaped area.
  • the central area includes two steps on which rests a profile 4 of electrically material conductor, such as copper, this profile 4 comprising a shaped part 4a staircase locally marrying the steps of the central area and extending to the exterior of the base 3 by a rectilinear part 4b extending in a direction substantially perpendicular to the underside of the base 3, the direction of extension of the rectilinear part 4b being a function of the environment of the connections.
  • the profile 4 has, at each step, a hole allowing the passage of a stud 5 carried by the base 3, this stud 5 being intended to allow the electrical connection of a cable 6 belonging to the circuit the vehicle to be connected.
  • Cable 6 has one end provided with a thimble 6a which is sandwiched between the profile 4 and an attached tightening nut 7 on the stud 5.
  • the rectilinear part 4b of the profile 4 comprises two sockets 8 made of material electrically conductive, for example made of copper, these sockets 8 being aligned one above the other on the longitudinal axis of the profile 4.
  • the sockets 8 are in contact electric with profile 4, for example being welded into an opening in the profile 4, and are adapted to receive connection pins 9 arranged at a end of the connecting cable 2 ensuring the electrical connection between the two cars of the vehicle, the sockets 8 and the pins 9 can be of different sizes.
  • the inside of the sockets 8 comprises a lamella contact, not shown in the figures, ensuring good electrical contact between the pin 9 and socket 8 when pin 9 is inserted in the latter.
  • each socket 8 is equipped a first coding ring 10 which is inserted inside the socket 8 and each pin 9 has a second keying ring 11 which is attached around connection pin 9.
  • the first and second rings 10, 11 have shapes adapted so that only the pins 9 provided with a second ring 11 of complementary shape of the first ring 10 present in the socket 8 can be fully inserted into the socket 8.
  • FIG. 4 represents in isolation an example of a pair of rings of coding 10, 11.
  • the rings 10, 11 include each a side edge comprising a lug 10a, 11a coming into a notch 10b, 11b of the lateral edge of the other ring when the rings 10, 11 are close together, the location of the pins 10a, 11a and notches 10b, 11b on the rings being specific to each connection module.
  • the associated keying rings 10, 11 have a clean color to distinguish them from other pairs of rings.
  • each pin 9 is provided with a groove 9a which comes opposite a slot 8a made on the body of the socket 8 and which receives, when the pin 9 is fully inserted into the socket 8, a locking clip 12 secured by a clip, this clip 12 making it possible to prevent any disconnection spindle involuntary 9.
  • the outer faces of the side walls of the connector base have grooves 3a forming a mortise and protuberances 3b in the form of a dovetail adapted to allow the assembly of the base 3 with one or more other bases 3 identical.
  • Such an assembly is shown in Figure 5 where we can see four connectors 1, identical to that of FIGS. 1 to 3, assembled together, these four connectors 1 also being assembled to two other connectors 21 produced according to another embodiment of the invention, these two connectors 21 comprising a base 3 identical to that of FIGS. 1 to 3 but comprising a profile fitted with a single socket.
  • the connector according to the invention thus has the advantage of allowing a large number of connections in a compact package.
  • the superposition of two sockets on the same profile allows the connection of two connecting cables in parallel, which allows, by keeping standardized connection cables, to double the power distributable by the connector without increasing the lateral dimensions of this latest.
  • the connector according to the invention is therefore particularly suitable for the connection of connection cables ensuring the electrical connection between two cars of a railway vehicle equipped with a distributed engine, i.e. when each car in the vehicle has a bogie fitted with a traction motor.
