A waterproof connector includes a housing having a fitting portion to be fitted into a mounting hole of a mating member. A packing mounting surface is provided on an outer peripheral surface of the fitting portion. The waterproof connector further includes a first packing mounted on a rear end side of the packing mounting surface in a fitting direction of the fitting portion, a second packing mounted on a front end side of the packing mounting surface in the fitting direction of the fitting portion, and a retainer provided between the first packing and the second packing and locked to a locking portion provided on the outer peripheral surface of the fitting portion.

A connector (F) includes an inner housing (11). Terminal fittings (72) are fixed to front end parts of wires (71) and are inserted into the inner housing (11) from behind. An outer housing (37) is held out of contact with the terminal fittings (72) and is mounted relatively displaceably with respect to the inner housing (11). Vibration damping rings (64) are fit externally on the wires (71) in a state out of contact with the inner housing (11), and are held resiliently in contact with the outer housing (37).

A connector (F) includes a housing (10), and terminal accommodating chambers (13) are formed in the housing (10). Terminal fittings (72) are fixed individually fixed to front end parts of the wires (71) and are inserted into the respective terminal accommodating chambers (13) from behind. Rubber plugs (61) are fit externally on the front end parts of the wires (71) and are configured to seal clearances between outer peripheries of the wires (71) and inner peripheries of the terminal accommodating chambers (13). Vibration damping rings (64) are formed on rear end parts of the rubber plugs (61). Vibration damping rings adjacent to each other are held resiliently held in contact with each other.

It is an object of the present invention to ensure a high water-stopping property of a wire harness including a waterproofing connector section that is molded from a resin, by suppressing a variation in the outer size of a seal section of the connector section. The connector section is made from a first synthetic resin that is insert-molded with a part of a terminal fitting of the terminated electric cable used as an insert section. A water-stopping section is made from a second synthetic resin that is insert-molded with a section extending from a part of the terminal fitting to an insulation coating of the terminated electric cable used as an insert section. The seal section is made from the second synthetic resin that is insert-molded with a part of the connector section used as an insert section. The second synthetic resin is softer than the first synthetic resin.

The present teachings provide for an electrical connector including a first housing, power terminals, and first and second shunts. The terminals and shunts are located within a cavity of defined by the first housing. The first housing is configured to mate with a second housing to transfer power between a power storage device and components of an electric or hybrid electric vehicle. The first shunt is configured to complete an interlock circuit. The second shunt is configured to complete a service disconnect circuit. The interlock circuit prevents the transfer of power between the first and second housings when the circuit is broken and allows it when complete. The service disconnect circuit causes the power storage device to be substantially electrically isolated from the rest of the vehicle when the circuit is broken.

A housing assembly for a waterproof connector includes a housing, a sealing device, and a protective cover. The housing has a sealing chamber receiving a seal. The sealing device is movable to cover the seal in the sealing chamber. The protective cover covers the seal and the sealing device.

A connector for a photovoltaic cell includes a conductive portion and an insulating portion, wherein the conductive portion is wrapped with the insulating portion; the conductive portion includes a conductor and a cable line, and a retaining ring is arranged on the outer circumferential surface of the conductor; the insulating portion includes a shell body, a basket-shaped fastener and a front sleeve; a first inner step surface and a second inner step surface are arranged in an inner cavity of the shell body; the front sleeve has an annular head part which sleeves the conductor; a first outer step surface is arranged at a tail part of the front sleeve, and props against the first inner step surface; the inner diameter of the head part of the front sleeve is larger than the outer diameter of the conductor and less than the outer diameter of the retaining ring.

A strain relief connector assembly for flexible electrical wiring is provided that includes an adapter that is configured to form a sealed connection to the wiring and a connector and to form a connection with a strain relieving device, which can include an arc of bend control mesh.

Disclosed is a system for testing the tightness of a cable gland feed-through of a partition, in particular of an immersible electrical connector, of the type including a cable gland body in which a seal and a cable gland rammer for compressing the seal are placed, characterized in that it includes a tightness testing ring inserted in the seal and provided with a bore opposite a hole of the cable gland body opening on same, and provided with a connection to a pressure/vacuum source for testing the tightness of the cable gland.

The present disclosure provides a connector improved in both assemblability and waterproofness. A connector is provided with a housing including a tubular wire inserting portion into which a wire member is partially inserted, a tubular rubber seal to be interposed between an inner surface of the wire inserting portion and an outer surface of the wire member, and a retainer for restricting escape of the rubber seal by being fixed to the wire inserting portion while being interposed between the inner surface of the wire inserting portion and the outer surface of the wire member. The rubber seal is formed with an annular recess recessed from one end surface and shaped to surround a through hole thereof. The retainer is provided with a fitting tube portion to be fit into the annular recess.
