An electronic device includes a device body and a male terminal structure connected to the device body. The male terminal structure includes a male terminal body, a first terminal member, and a free terminal member. The male terminal body is connected to the device body and a mating electronic device, respectively. The first terminal member is disposed at an end portion of the male terminal body, and the first terminal member is capable of being received in a terminal inserting portion of the mating electronic device. The free terminal member is disposed at the end portion of the male terminal body, detachably in contact with the first terminal member, and capable of being in contact with a secured terminal member of the mating electronic device.

An automotive booster cable system includes a first battery clamp attached to a first battery a second battery clamp attached to a second battery; an optional electrical plug adapter with an adapter electrical connector for mating with the second battery clamp; and a booster cable assembly having a first polarized electrical booster connector for mating with the first battery clamp and a second polarized electrical booster connector for mating with either the electrical plug adapter or the second battery clamp.

The invention is a jump starting system for conducting a charging operation with various combinations of two automotive batteries in which one or both batteries is either a conventional battery, a battery with embossed electrical contact sockets, or a battery with internal electrical contact slots, where electrical connection between batteries is established by means of a battery jumper plug cable having four electrical jumper plugs electrically attached to respective ends of a positive insulated conductor and a negative insulated conductor.

A battery apparatus includes a flexible flat cable and a busbar. A collection end of the flexible flat cable is provided with a collection component. A larger surface of the busbar is provided with a connection hole, and the collection component is inserted into the connection hole. The collection component and/or the busbar is provided with a first limiting structure for mutually limiting the collection component and the connection hole.

An electronic device includes a device body and a female terminal structure connected to the device body. The female terminal structure includes a female terminal body, a tunnel, a second terminal member, and a secured terminal member. The female terminal body is connected to the device body and a mating electronic device, respectively. The tunnel is recessed from the female terminal body. The second terminal member is disposed at the female terminal body and received in the tunnel. The second terminal member has a terminal inserting portion. The secured terminal member is disposed at the female terminal body, spaced from the second terminal member, and disposed on an outer periphery of the extension portion. The extension portion is substantially flushed with the secured terminal member. The second terminal member is not flushed with the extension portion. The second terminal member is enclosed by the extension portion.

A busbar for use in mechanically and electrically connecting components in a device or system. The busbar includes a plurality of conductors arranged to provide two opposed end portions and an intermediate portion, wherein each of the conductors has a plurality of intermediate extents that traverse the intermediate portion. The intermediate portion including: (A) an unfused segment where no intermediate extents of the conductors are fused together to form a single consolidated conductor, and (B) a fused segment that includes (i) a partial solidification zone where a majority of the intermediate extents of the conductors are fused together to form a partially solidified region that provides a single consolidated conductor, (ii) a full solidification zone where all of intermediate extents of the conductors are fused together to form a fully solidified region that provides a single consolidated conductor, and (iii) an unsolidified region where all of the intermediate extents of the conductors are not fused together.

A bus bar assembly includes a nonconductive terminal cap configured to at least partially surround an electrically conductive terminal. The terminal cap has a perimeter wall configured to circumscribe at least a portion of the terminal to provide a gap configured to expose the terminal. The terminal cap includes a first attachment feature. The bus bar assembly also includes a bus bar having an end configured to mechanically and electrically engage the terminal in an assembled condition and a nonconductive shroud enclosing the bus bar. The shroud includes a second attachment feature configured to removably engage the first attachment feature in the assembled condition to secure the shroud to the terminal cap. A method of electrically connecting cells of a battery is also provided.

Disclosed are a connection assembly for a battery module and a battery module. The connection assembly for a battery module has a housing body, a cover plate and an openable and closable door, wherein the housing body is used for supporting a plurality of components; the cover plate covers the housing body and used for covering the plurality of components on the housing body; the cover plate is provided with a second through-hole, and the second through-hole positionally corresponds to at least one of the plurality of components; the openable and closable door is movably mounted on the cover plate, and is positionally changeable between an open position and a closed position; wherein in the open position, the openable and closable door opens the second through-hole to expose the at least one of the plurality of components; and in the closed position, the openable and closable door shields at least part of the second through-hole to cover the at least one of the plurality of components on the body. A contact state between a temperature sensor and a cell can be examined by means of the second through-hole.
