Description

Bidirectional electrical connection female base and bidirectional electrical connection male head and combinations thereof

The invention relates to an electrical connector, in particular to an electrical connection female base and an electrical connection male head capable of bidirectional electrical connection.

At present, the most popular signal transmission specification of computer equipment is the Universal Serial Bus (USB). The connector socket and transmission line made with this specification can be connected to the peripheral equipment of the computer, such as mouse and keyboard. Instantly measured by the computer and used immediately.

At present, both the USB electrical connector and the USB electrical connector are unidirectional electrical connections. In order to ensure that the USB electrical connector can be electrically connected when inserted into the USB electrical connector, the two have a foolproof design on the docking, that is, when the USB electrical connection When the connector is inserted in the reverse direction, it cannot be inserted, and the user will insert it in another direction. The direction is correct before inserting, so as to ensure that there is electrical connection after insertion.

At present, USB has two specifications of 2.0 and 3.0. Please refer to FIG. 1 and FIG. 2, which is a type A standard USB2.0 electrical connection female base 10 regulated by the USB Association, which is provided with an insulating base 12 and a metal shell 13 The front end of the insulating base 12 is provided with a tongue plate 121 protruding horizontally forward.
