An electrical connector includes a contact button having a first layer formed of a first electrically conductive material that is attached to a first electrical bus bar and having a second layer formed of a second electrically conductive material clad to the first layer. The electrical connector includes a clamp assembly including a retaining band surrounding the contact button and the first electrical bus bar and having a spring configured to provide a contact force between the contact button and a second electrical bus bar when the second electrical bus bar is disposed between the contact button and the spring.

A method and apparatus for securing an electrical connection formed by a mating structure including prongs of a male assembly and receptacles of a female assembly are provided. In certain embodiments, the electrical connection can be secured by frictional engagement between the plug and receptacle housings. This can be accomplished by forcing a wedge into an interface between the housings or expanding a locking element, such as an elastomeric ring, into the interface. Such locking and releasing of the secure connection can be actuated using a locking nut.

A terminal module (10) has a metal case (20) with a ceiling wall (21), a bottom wall (51) facing the ceiling wall (21), opposed side walls (23) extending from the ceiling wall (21) toward the bottom wall (51) and retaining pieces (24). A coil spring (40) is sandwiched between the ceiling wall (21) and the bottom wall (51). The retaining pieces (24) face each other in a direction perpendicular to a facing direction of the side walls (23) and project toward the bottom wall (51) from the periphery of the ceiling wall (21). The side walls (23) and the retaining pieces (24) are disposed alternately on the periphery of the ceiling wall (21). A spring receiving portion (26) formed by the ceiling wall (21), the side walls (23) and the retaining pieces (24) receives an end part of the coil spring (40) on the side of the ceiling wall (21).

Disclosed is a charging connector for a trolley having a power storage module, including a body carrying a circuit and a first electrode plate and a second electrode plate provided at two ends of the body respectively, the first electrode plate and the second electrode plate being electrically connected through the circuit and the first electrode plate or the second electrode plate having an elastic arch portion with a variable arch height. The charging connector can keep the elastic contact between the second electrode of a front charging connector and the first electrode of a rear charging connector during front-back series connection, eliminating the defect that the current charging connector has bad contact. The trolley with the connector can be charged reliably and the power energy can be used to a peripheral device onboard the trolley. Such a multimedia trolley does not need repeated manual checking.

Connector (1) comprising at least one female part (2) and at least one male part (3) engaging in the female part, and locking means (4) preventing any extraction of the male part from the female part, characterized in that the locking means comprise at least one removable locking part (4) arranged as an interface between the male part (3) and the female part (2), and the male and female parts comprise means of retention (24, 35) by mutual cooperation, the mutual disengaging of the retention means being rendered possible only after the withdrawal of the locking part.

An electrical contactor assembly includes an electrical contactor having an electrical lead having a contactor pin extending therefrom, an electrical bus bar, and at least one post extending between the electrical contactor and the electrical bus bar. The post is constructed from an electrically and thermally conductive material. The post includes an opening for receiving the contactor pin and the opening includes a contactor-foil material disposed in contact with the pin.
