ABSTRACT:
An electrical connector assembly for a cable having a plurality of insulated conductors comprises a body having a respective recess for receiving a terminating pin each of the conductors. A respective spigot sealingly engages within each of the recesses and has a passage for receiving an associated one of the terminating pins. Furthermore a seal is associated with each of the spigots for sealing the spigot relative to the associated terminating pin. The provision of a separate spigot for each of the conductors and for sealing engagement within a respective recess in the body enables the spigots to be sealingly fitted to the conductors prior to each spigot being introduced into its recess and sealingly engaged therein. This provides improved insulation of the conductor and increased creepage distance between the mating electrical parts and the outer surface of the housing of the assembly. It also provides the additional advantage that the seal on the conductor tends to be smaller than in prior arrangements so that there is less thermal expansion of the seal when the parts get hot in a downhole environment.
