An electrical connection device includes a first connector and a second connector. The first connector includes an insulative body and a plurality of first terminals provided to the insulative body, the insulative body has an insertion groove, a first insertion opening which is communicated with the insertion groove and toward a first direction, a second insertion opening which is communicated with the insertion groove and toward a second direction and a stopping block which is positioned between the first insertion opening and the second insertion opening, the stopping block has a first stopping face which faces the first direction and a second stopping face which faces the second direction. The second connector includes an insulative housing and a plurality of second terminals provided to the insulative housing, the insulative housing has a mating portion and a contacting surface, when the second connector is mated with the first connector along the first direction, the mating portion is inserted into the insertion groove from the first insertion opening, and the contacting surface is stopped by the first stopping face of the stopping block, when the second connector is mated with the first connector along the second direction, the mating portion is inserted into the insertion groove from the second insertion opening, and the contacting surface is stopped by the second stopping face of the stopping block.

A high-current high-frequency electrical connector receptacle applicable to network data transmission includes a receptacle housing and a socket tongue. The socket tongue is inserted into the receptacle housing in a front-rear direction, and a relative position thereof is locked. The socket tongue includes an upper terminal block, a lower terminal block and an insulating plastic body. The upper terminal block and the lower terminal block are both built in and fixed into the insulating plastic body. The receptacle housing is provided with a special-shaped fool-proofing unit.

A charging socket includes a housing formed of an electrically insulating material, a cavity in the housing receiving an electrical contact, and a dual-functional element partially protruding from an outer surface of the housing. The dual-functional element has a fixing component and a drainage component. The fixing component protrudes from the housing and fixes the housing to a mounting bracket. The drainage component has a drainage channel within the housing discharging fluids from the charging socket.

A terminal for connecting electric wires and a connector using the same provide a terminal which includes a main body part having a band shape, a first connection part, and a second connection part and in which the first and second connection parts are curved at a right angle to each other so that electric wires are connected in the state in which the electric wires are intersected and arranged at a right angle to each other. Accordingly, a flow of a current can be branched through a simple terminal structure. As a result, a current can be supplied to various supply places through the minimum part.

An electrical connector includes multiple conductive terminals respectively retained in multiple accommodating slots of an insulating body. Each conductive terminal includes a base portion, a connecting portion extending from one side of the base portion, a first elastic arm and a second elastic arm extending from the connecting portion toward a direction away from the same one side of the base portion, and at least one fixing portion extending from another side of the base portion. A width of the connecting portion is less than a width of the base portion and less than a width of a location of the first elastic arm near the connecting portion as well as a width of a location of the second elastic arm near the connecting portion. The fixing portion and the first elastic arm are respectively located at different sides of the base portion, thus achieving good elasticity and thinness.

An electrical connector, for being mounted on a circuit board, includes a metal shell and a terminal module. The metal shell includes a mounting surface to be matched with the circuit board. The terminal module includes a number of conductive terminals, an insulating block, a ground shielding piece and a number of cables. The conductive terminals include a number of pairs of differential signal terminals, a number of first ground terminals, and a number of second ground terminals. The ground shielding piece connects the first ground terminals and the second ground terminals in series. Each conductive terminal includes a mating elastic arm extending beyond the mounting surface. The mating elastic arm includes a contact portion for pressing against a conductive pad of the circuit board, thereby improving the installation convenience of the electrical connector.
