Abstract: In order to provide watertight properties between a spring socket (1) and a release socket (2) for a plug of a push-pull connector, a bellows expansion joint (5) is provided between the spring and release sockets. When the two sockets are spaced apart, the bellows expansion joint is in the rest (non-stressed) position. When the release socket is driven closer to the spring socket, a stress is exerted on the bellows expansion joint (6, 7). This helps to force back the release socket. By this structure, improvements are shown in the vibration resistance and, at the same time, in the watertightness of the plug of a push-pull connector.

Abstract: A panel lock connector includes a connector housing having chambers formed therein for accommodating electrical terminals and a spacer inserted into the connector housing in a direction perpendicular to a direction along which the terminals are inserted into the chamber. The connector housing is provided in a peripheral wall with an opening and flexible lock arms each of which has an engagement projection to be engaged with a hole formed in the panel.

Abstract: An electrical connector assembly is comprised of an insulating housing for fixed mounting within an automotive body behind panel walls. A mating connector has a housing portion and a peripheral shroud. The shroud has integral latches which retain the shroud and housing together, and the shroud includes latches which retain the shroud to the panel. Actuating lugs are positioned on the front of the housing portion and are profiled for receipt within a groove on a camming slide. The latches hold the shroud and housing together during the actuation of the lugs and the camming slide. When the latches are locked behind the panel wall, the shroud inner surface contacts the panel wall, whereby the latches break free of the corresponding lugs on the housing. Continued actuation of the U-shaped camming slide moves the connector housing into fully locked position, leaving the shroud positioned against the wall.

The outer portion of the head consists of a plurality of thick oblique ribs that fold inwardly to reduce the outer diameter of the head responsive to twisting movement of the head in the hole so that a relatively low engage force passes the head through the hole. The grommet further includes a conical shoulder which sealingly engages the front side of the panel and clamps the lamp socket in place.

Abstract: A connector is described which can be easily installed in a hole of a barrier wall, which assures tight sealing when there is a substantial pressure difference on opposite sides of the wall, and which avoids set of the sealing material. The connector includes a frame with a radially inner portion and with a skirt extending around the inner portion and slightly bendable radially outward and inward. O-rings are mounted on the outside of the skirt, so when pressure causes the skirt to expand, the O-rings form a tight fit against the surface of the hole, while when pressure is relieved the seals are pressed with less force and avoid becoming set. A group of thin limiters extend between the skirt and the inner frame portion. The limiters allow the skirt to expand radially outwardly, but limit radially inward deflection of the skirt to assure that even when there is no pressure the O-rings push firmly against the hole surface.
