A connector includes a terminal fitting, a housing, a front holder to which an engagement part of the housing is inserted along an inserting direction of the engagement part with respect to a counterpart engagement part, and a water-stopping member with an annular shape that closes an annular space between a projection part from the front holder at an outer peripheral wall surface of the engagement part and an inner peripheral wall surface of the counterpart engagement part. The front holder includes a retained part that projects toward the outer peripheral wall surface of the engagement part. The water-stopping member includes a retained part that projects inward relative to an inner peripheral surface. The engagement part includes a communication retaining part where a first retaining part and a second retaining part are provided in a communicating state.

A connector unit comprises: a connector having terminals connected to the terminal parts of wires, and a housing for holding the terminals; and a cylindrical connector cover that is made of an elastic material and that covers the housing. The connector has a connector position guarantee component for guaranteeing correct fitting into a counterpart connector. The connector cover has an open window for exposing the connector position guarantee component to the exterior of the connector cover, and a lid part for covering the open window in an openable/closable manner.

A contact assembly for a connector housing includes an adapter element and a contact element. The adapter element has a sleeve with a lead-through opening extending in an axial direction of the sleeve and with a threaded bore extending perpendicularly to the lead-through opening through the sleeve. The contact element is adapted to be inserted into the lead-through opening and latched to the sleeve. The contact element may exhibit varying types of a cable connection section and/or a contact section. The adapter element is receivable within the connector housing and may accept the contact element regardless of the type of cable connection section and/or contact section.

A separable high-voltage connector assembly which can miniaturize a size by individually separating each first pin of a connector mounted on a board to form multiple small connectors and simplify a process and prevent an error that connectors are incorrectly inserted into each other by forming an inserting connector through fastening and assembling each of individually separated second pins.
