An insert attachment for covering a jack of cable cord, the insert attachment including a housing with a rear and front portion wherein the front portion diameter is greater than the rear portion diameter. The insert attachment may include a protective sleeve. The insert attachment may further include inner and outer coating layers on the surface of the housing with various density or hardness.

Protective cover devices for associated electrical connectors include a one-piece molded polymeric body including at least one of: (i) at least one stud that is closely slidably received into a corresponding socket of the connector; (ii) a skirt that comprises a recess that receives at least part of the electrical connector therein. The protective cover device is adapted to be engaged with the associated electrical connector to inhibit contact between a surrounding corrosive atmosphere and at least one electrical contact of the associated electrical connector.

A cover for an electrical connector may include an outer wall having a first edge and a second edge, a first side wall connected to a first end of the outer wall, a second side wall connected to a second end of the outer wall, a first clip portion disposed proximate the first edge and configured for rotational connection with a first wire frame portion, and/or a second clip portion disposed proximate the second edge configured for connection with a second wire frame portion.

A waterproof power plug includes a mounting frame, first and second conductive terminals, a fuse, and a fuse cover which are mounted inside the mounting frame. The fuse is electrically connected to the second conductive terminal. The mounting frame is provided with a mounting groove for exposing the fuse, and the fuse cover is mounted in the mounting groove to cover or expose the fuse. The power plug further includes a housing opened with a window for slidably operating the fuse cover, and a waterproof cover is mounted in the window. Therefore, the fuse cover is arranged on the mounting groove and the waterproof cover is further covered on the fuse cover, which provides multiple waterproof protections. The power plug has a good sealing performance and waterproof performance, which also helps to improve the overall waterproof performance and work safety of the string light with the power plug.

A high-power plug connection system has a cable connection housing for connecting at least two electric high-power plug connectors in order to transmit and/or distribute a high current strength and/or a high electric voltage. The cable connection housing receives at least two insulating bodies for receiving at least one respective high-power contact and at least one electrically conductive rail in an interior. The rail is designed to establish an electrically conductive connection between the at least two high-power contacts, and the insulating bodies protrude at least partly out of the interior through a respective housing opening and into a connection region, the connection region being designed to receive the high-power plug connector.

The invention relates to a cable lug (10, 10′, 10″, 10′″) having a connection region (9, 9″, 9′″) for connecting the cable lug (10, 10′, 10″, 10′″) to an electrical conductor (4) and having a contact part (11) for establishing contact with a terminal part (40) of an electrical system (42), in particular of an electrical system of a motor vehicle, the contact part (11) comprising a fastening opening (12) for guiding therethrough a fastening element (46) for fastening the cable lug (10, 10′, 10″, 10′″) to a terminal part (4), and wherein the contact part (11) comprises one or more further openings (13). The invention further relates to the use of the cable lug (10, 10′, 10″, 10′″), a contact element (2) with such a cable log (10, 10′, 10″, 10′″) as well as to a method for producing the same.

A connecting apparatus comprising a holding member and a conductive member. The holding member has holding portions. The conductive member has a plurality of held portions, a plurality of contact portions, a plurality of extending portions and a plurality of coupling portions. Each of the extending portions extends rearward in a front-rear direction from one of the held portions and protrudes rearward in the front-rear direction beyond the holding portion. The extending portions are positioned apart from each other in a right-left direction. The coupling portions are positioned apart from each other in the right-left direction. The coupling portions are positioned rearward of the extending portions in the front-rear direction. Each of the coupling portions couples two of the extending portions with each other. Two of the held portions, which are adjacent to each other in the right-left direction, are coupled with the two extending portions, respectively.

A corrosion prevention structure for connectors includes: a boot which covers plural connectors for power distribution to be concentrated together on a front side of a battery and through which plural cables extending respectively from the plural connectors are inserted; and a clamp which tightly binds the plural cables over the boot.

An electro-mechanical connection apparatus. The apparatus includes a connection base configured to mechanically support an external device, and a first connection device operably connected to the connection base, wherein the first connection device is configured to operably connect with a second connection device associated with the external device. The first connection device includes a first electrical contact configured to establish an electrical connection with a second electrical contact of the external device, wherein the first electrical contact establishes the electrical connection with the second electrical contact while the connection base mechanically supports the external device.

A connector assembly includes a connector, a housing having an insertion port, and a waterproof cap detachably attached to the housing to close the insertion port, the waterproof cap having a cap body, a first protruding portion continuously surrounding an entire periphery of an outer peripheral surface of the cap body, and a second protruding portion disposed on a front end side of the cap body in a fitting direction from a position at which the first protruding portion is disposed, when the waterproof cap is attached to the housing, the first protruding portion being press-fitted to the insertion port and contacting an entire periphery of an inner peripheral surface of the insertion port while being elastically compressed, the second protruding portion being inserted into the connector and contacting at least two inner surfaces of the connector facing each other while being elastically compressed.
