Description

Two-way electrical connection female seat and two-way electrical connection male joint and combination thereof

The present invention relates to an electrical connector, and more particularly to an electrical connection base and an electrical connection male that can be electrically connected in both directions.

The most popular signal transmission specification for today's computer equipment is the Universal Serial Bus (USB). The connector socket and transmission line made by this specification can be connected to the peripheral devices of the computer, such as a mouse and a keyboard. Instantly measured for your computer and used immediately.

At present, the USB electrical connection socket and the USB electrical connection connector are all unidirectional electrical connections. In order to ensure that the USB electrical connection connector can be electrically connected when the USB electrical connection connector is inserted, 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 the other direction, and the direction is correct to insert it. This ensures electrical connection after insertion.

Currently, USB has 2.0 and 3.0 specifications. Please refer to FIG. 1 and FIG. 2, which is a type A eccentric USB2.0 electrical connection base 10 specified by the USB Association, and is provided with an insulating base 12 and a metal casing 13.
