Definitions

  • the invention relates to an electrical connector for a motor vehicle, comprising:
  • These connectors are typically used for electrical connection between electrical communication devices.
  • indicators are often incorporated into circuits on the printed circuit board. These indicators are typically light emitting diodes which are turned on when a circuit is completed between the mating connectors and the communication devices. Additionally, LEDs can be mounted on the printed circuit board to indicate a number of other conditions including the passage of communication signals between the two communication devices, an indication of power supply status, indication that an error in transmitting the signals has occurred, or used for debugging purposes during development.
  • Such connectors can be used in vehicles for construction, agricultural forestry, municipal, industrial and/or railway applications.
  • Electrical connectors of prior art accomplish such indicators with LEDs, light guides, adhesives and/or coloured films, but thereby cause a higher risk of leaking in the assembly due to more and different sealing interfaces, which can come apart due to aforementioned conditions in a motor vehicle.
  • the at least one light indicator area and the insulative housing are made of one material, wherein the at least one light indicator area is formed integrally with the insulative housing.
  • the at least one light indicator area acts as a status indicator for the electronic connector or the at least one jack receptacle connectors.
  • LED light emitting devices
  • the light entry surface and the light exit surface are parallel to each other, wherein the light entry surface and the light exit surface have a distance to one another from 0,8 to 1,3 mm, preferably 0,8 mm.
  • the light entry surface and the light exit surface are parallel and opposite to each other, wherein the distance between the light entry surface and the light exit surface is smaller than the thickness of the direct surrounding section of the insulative housing.
  • the light emitting device has a main propagation direction and is disposed such that the main propagation direction is orthogonal to the light entry surface of the at least one light indicator area.
  • the electrical connector comprises at least two or more, preferably exactly two jack receptacle connectors, wherein the insulative housings of each jack receptacle connector are formed together in one piece.
  • the insulative housing together with the light indicator area is fabricated by injection moulding.
  • the insulative housing is made of polybutylene terephthalate with glass fibre content of 10 % to 50%, preferably 20% to 30%, particularly with 30% (PBT GF30).
  • the insulative housing preferably made of polybutylene terephthalate, is not colored.
  • the material contains only the most necessary additives for environmental resistance and only those that do not greatly reduce the light transmission.
  • the material of the insulative housing comprises flame-retarding additives.
  • the circuit board, the light emitting devices and parts of the jack receptacle connectors for connecting the jack receptacle connectors electrically with the circuit board are housed in a housing, wherein the housing is connected with the insulative housing via at least one fixing means.
  • the fixing means can be an adhesive.
  • Fig. 1 shows an electrical connector 10 for a motor vehicle, comprising two jack receptacle connectors 100, which comprise an insulative housing 200 with a mating face 210, wherein on the mating face 210 of the insulative housing 210 one cavity 220 profiled to receive a complementary plug for each jack receptacle connector 100 is arranged.
  • the insulative housing 200 further comprises three light indicator areas 300, shown in Fig. 2 . It should be noted, that more or less light indicator areas are possible.
  • the light indicator areas 300 are at least partially translucent and each has a light entry surface 310 and a light exit surface 320 opposite to the light entry surface 310 for emitting light in the direction of the mating face 210 of the insulative housing 200.
  • the electrical connector further comprises a circuit board 400 (which can be seen in Fig. 1 and Fig. 3 ) on which the jack receptacle connectors 100 are electrically connected, wherein the circuit board 400 comprises three light emitting devices 500, each of which is assigned to a light indicator area 300 and is configured to emit light towards the light entry surface 310 of the at least one light indicator area 300.
  • the light emitting devices 500 have a main propagation direction X1 and are disposed such that the main propagation direction X1 is orthogonal to the light entry surface 310 of the assigned light indicator area 300.
  • the circuit board 400, the light emitting devices 500 and parts of the jack receptacle connectors 100 for connecting the jack receptacle connectors 100 electrically with the circuit board 400 are housed in a housing 600, wherein the housing 600 is connected with the insulative housing 200 via at least one fixing means.
  • the fixing means in the shown example in the figures is an adhesive.
  • the light entry surface 310 and the light exit surface 320 are parallel to each other, wherein the light entry surface 310 and the light exit surface 320 have a distance to one another from 0,8 to 1,3 mm, preferably 0,8 mm.
  • all light indicator areas 300 and the insulative housing 200 are made of one material, wherein the light indicator areas 300 are formed integrally with the insulative housing 200, e.g. by injection moulding.
  • the insulative housing 200 and the indicator areas 300 could be made of polybutylene terephthalate with glass fibre content of 10 % to 50%, preferably 20% to 30%, particularly with 30% (PBT GF30).
