A wall-mounted electrical-connector-engaging assembly for axial engagement with an electrical connector, the assembly including (a) a wall-surface adapter having front and back faces and attached to a wall over an opening in the wall and (b) a backcap. The adapter back face has a plurality of wire-connection points for installation of a corresponding plurality of wires, and the adapter front face has a plurality of slidably-engaging electrical connection points for engagement in at least an axial direction with the electrical connector. The backcap surrounds the plurality of wire-connection points and adjacent portions of the corresponding plurality of wires connected thereto, and includes a twist lock for installation on the wall-surface adapter.

A charging connector is provided with a mating portion, a main portion, a body and a fasting member. The main portion is provided with a plurality of contacts, which are respectively connectable mating contacts of a mating connector, and a housing, which holds the contacts. The body accommodates the main portion at least in part and holds the main portion. The mating portion is located forward of the body in a front-rear direction. The fasting member fastens the mating portion to the body. The fasting member is not brought into contact with the housing at least in the front-rear direction.

The present disclosure relates to a cable connector structure, which includes a housing, a tongue plate, a plurality of cables, and a plurality of heat sinks. The housing includes a docking end and a butting end. One side of the housing includes a top surface, and the top surface protrudingly provided with a hollow stage. The tongue plate is arranged in the housing, one end of the tongue plate is provided with a docking area, and the other end of the tongue plate is provided with a welding area. The plurality of heat sinks is arranged on the top surface of the housing, the hollow stage is arranged toward the docking end and the plurality of heat sinks are arranged toward the butting end.

A locking device adapted to lock a shell to an installation body includes a thread connection member extending through a connecting hole in the shell and engaging a threaded hole in the installation body, a sealing ring sleeved on the thread connection member and adapted to be pressed on an installation surface of the shell to seal the connecting hole of the shell, and a gasket sleeved on the thread connection member and adapted to be pressed between the thread connection member and the sealing ring to prevent the thread connection member from being loosened. The gasket has a pair of stopping arms. An angle defined between the stopping arms is greater than 0 degrees and less than 180 degrees. A pair of top ends of the stopping arms are adapted to simultaneously abut against an outer wall of the shell to prevent the gasket from rotating with the thread connection member.

A battery apparatus includes a casing and at least one first insert disposed on the casing. The first inserts has an electromagnetic shielding layer. The battery apparatus further includes at least one second insert disposed on the casing. The first insert and the second insert are arranged at intervals. The electromagnetic shielding layer of the first insert is electrically connected to the casing through the second insert.
