Definitions

  • the present invention relates to improvements to the devices enabling the electrical connectors to be sealed.
  • An electrical connector is generally constituted in its simplest form by two parts made of an insulating material and each containing a metallic member, or contact, connected to the end of an electrical conductor. By engaging the two parties in one another, the contacts are made to cooperate.
  • the annular orifice formed between the entry orifice of the insulating part and the external surface of the cable is closed by a sleeve made of a very soft synthetic rubber made integral with the tail of the contact. by crimping.
  • This sleeve is engaged on the cable and positioned on the latter prior to the connection of said cable to the tail of the contact which has, for this purpose, two additional crimping lugs similar to those used to fix the end of the cable to said contact.
  • the sleeve must have a stepped part to allow crimping, which complicates its manufacture; the crimping of the sleeve is only possible if the latter is rigorously positioned relative to the stripped end of the cable, hence an additional operation prior to crimping; crimping complicates the production of crimping machines; the fixing of the sleeve is very random due to its extreme flexibility and the crimping must be carried out with great precision.
  • the present invention which overcomes these drawbacks, is remarkable in that the sealing sleeve is overmolded on the end of the tail of the contact.
  • the electrical contact comprises two usual parts 1 and 2, that 1 constituting the contact member proper while that 2 forms a tail to which the electrical cable C is connected.
  • the tail 2 has two pairs of lugs 3a and 3b, the lugs 3a being crimped on the stripped end of the cable C while those 3b are crimped on the insulation of said cable.
  • a sleeve 4 made of a very flexible natural or synthetic rubber is molded onto the end of the tail 2, extending beyond the legs 3b.
  • the end of the tail has an extension 5 suitably cut and arched which after over / molding of the sleeve is embedded in the latter and cooperates in its maintenance.
  • the external diameter of the sleeve is greater than that of the internal housing L of the connector to receive it and that of its central opening 6 is slightly greater than that of the cable C.
  • the cable freely crosses the sleeve which, thus, does not interfere with the positioning of the cable prior to its attachment to the contact.
  • the sleeve enters the housing L of the connector, the material constituting it then compresses around the cable, ensuring sealing.
  • the outer periphery and the inner periphery of the latter have grooves 7.
