Description

Electrical connector

The present invention relates to an electrical connector, and more particularly to a plug connector that can be used for both front and back insertion.

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 peripheral devices such as a mouse and a keyboard. Instantly measured for your computer and used immediately. Since the current standard USB plug has only one row of contacts on one side, and the USB socket is provided with a row of contacts on one side of the tongue, the USB plug needs to be inserted in the correct direction to make the contacts of the two contacts. Realize electrical connections. In order to ensure that the USB plug can be electrically connected when inserted, the two have a foolproof design on the docking, that is, when the USB plug is inserted in the reverse direction, the user cannot insert it, and the user will insert another direction, and the direction is correct to insert. The user usually inserts randomly, so the probability of not being inserted is 1/2, so it is often inserted twice, causing inconvenience in use.
