Abstract: An electrical connector comprises a first housing member and a terminal position assurance member. The terminal position assurance member is fully received within the housing such that it can not be accidentally depressed into the fully locked position during handling and transport. The terminal position assurance member is moveable from a pre-assembly to a fully locked position in a direction transverse to the mating direction such that the housing has a substantially flush front face to enable the connector to be mated against a wall or similar structure in a compact manner. Movement of the terminal position assurance member in the transverse direction ensures that the outer shroud of the connector does not extend beyond the mating face of the connector, thereby providing a compact arrangement.

Abstract: A fuel pump unit comprises a pump supporting flange for closing an opening in a fuel tank. The supporting flange has a wet side from which projects a fuel pump and an opposite dry side from which projects a lip defining a through opening in the supporting flange. An electrical connector has a mating portion for mating with a further connector connected to the power supply for the pump. There depends from the mating portion an insulating block into which have been moulded electrical tabs each having one end projecting into the mating portion and the other end projecting below the insulating block. Leads are connected to these lower portions of the tab terminals by means of electrical clips. The connector is inserted through the opening in the supporting flange from the wet side thereof so that a resilient skirt surrounding the insulating block is force fitted to the inner surface of the lip and a sealing ring is compressed by a flange at the bottom of the skirt, against the wet side of the supporting flange.
