The housing has a slot therein adjacent to the front open end thereof. At least one contact terminal is inserted into the chamber from the rear open end of the housing. A spacer is inserted into the slot in such a manner that the spacer can be slidingly moved to a final locked position in a direction perpendicular to the axis of the contact terminal.

Abstract: An electrical connector (2) is adapted at its forward end for insertion from the rear forwardly within a through opening (10) contained in a base member (1). A snap fastener retaining arrangement including a pair of resiliently outwardly biased hook members (6) on opposite sides of the connector is adapted to automatically engage corresponding shoulders on the base member when the connector has been inserted to a given position within the base member opening. The connector is thus releasably retained in position, whereupon the connector may be rigidly fastened to the base member by second fastener devices (4) operable from the front of the base member. Upon disconnection of the second fastener devices, the hook members may be manually compressed inwardly toward the connector to release the snap fastener retaining arrangement, whereupon the connector may be withdrawn from the base member opening.

Abstract: An electrical connector, particularly adapted for use in motor vehicles, having an outer wall, a housing cap adapted to cover the front end of the housing, and one or more wire assemblies each having a terminal recess on the inside surface thereof. The assembly is adapted to be inserted into the housing from the rear and the housing has a corresponding number of receiving passages extending longitudinally therethrough. There is a narrowed portion of the passages which forces the assemblies being inserted outwardly against a deflectable arm in the outer wall. When the assembly is completely in place, the narrowed portion fits into the terminal recess, thereby permitting the flexible portion of the outer wall to return to its normal position. Thus, unless the assemblies are fully seated, the housing cap cannot be fitted over the housing, thereby preventing misassembly of the connector.

Abstract: An electric connector including a housing made of resin and having a plurality of cavities for receiving a plurality of terminals and a terminal retaining member made of resin and having a plurality of holes. When a rear portion of the housing is inserted into an opening formed in a front portion of the terminal retaining member, the housing and terminal retaining member are preliminarily coupled with each other in a first coupling mode in which the holes of the terminal retaining member are aligned with the cavities of the housing. After the terminals having electric wires connected thereto have been inserted into the cavities through the holes, the terminal retaining member is shifted in a direction perpendicular to a direction in which the terminals are inserted and then is further moved toward the housing to attain a second coupling mode. In the second coupling mode the terminals are engaged with portions of the terminal retaining member to prevent the terminals from being removed out of the housing.

Abstract: An improved arrangement for retaining a terminal in a terminal holder includes providing a mounting opening through a wall of the terminal and provides a resilient snap-lock extending from the surface of a support member of the holder. The snap-lock extends through the terminal mounting opening for preventing relative longitudinal motion of the terminal in the holder and for yieldably restricting relative motion of the terminal substantially normal to the support member of the holder. The snap-lock has two locking fingers extending in "V"-shape fashion from the support member, which is preferably the holder's base. The locking fingers include camming surfaces to facilitate mounting the terminal on the locking fingers by moving the terminal transverse to its longitudinal extent. The holder is open at its top to facilitate mounting and removal of a terminal. A connector housing may be provided to removably close that opening.

The outer seal member encircles both the terminal holder and the conductor wires at least in partial coincidence with the inner seal member. The outer seal includes circumferential ribs for sealing engagement with the periphery of the opening in the housing. A face seal between the forward end of the holder and the housing seals pin terminals when inserted into receptacle terminals in the housing.

Abstract: A retention article for retaining closely-spaced terminals in a connector housing is formed having a stiff water-like article of thermoplastic material and elastomeric material therearound, with a plurality of holes extending therethrough. A pair of arcuate, partly converging wall sections partly surround each hole of said water-like article and extend forwardly from a planar section thereof having forward ends acting as stop surfaces to engage a stop shoulder on each terminal inserted therein. Elastomeric material forward of the planar section surrounds and abuts the outside surfaces of the wall sections, so that when a terminal is inserted into a hole of the retention article it slightly expands the stiff wall sections apart until the stop shoulder passes the forward ends, and the elastomeric material acts to urge the wall sections together against the terminal behind the stop shoulder.
