Description

Two-way electrical connection maternal and two-way electrical connection male

The present invention relates to an electrical connector, and more particularly to an electrical connection female 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 two specifications, 2.0 and 3.0. Please refer to FIG. 1 and FIG. 2, which is a type A standard USB2.0 electrical connection base 10 standardized by the USB Association, and is provided with an insulating base 12 and a metal outer casing 13. The front end of the insulating base 12 is provided with a horizontally forwardly protruding tongue 121. The metal casing 13 covers the insulating base 12 and forms a connecting groove 16 to cover the tongue 121. The connecting groove 16 is A small space 161 and a large space 162 are formed above and below the tongue plate 121, and the insulating seat body 12 is provided with a row of four first terminals. The first terminal 14 is provided with a contact portion 141 that can be bounced up and down to protrude from the bottom of the tongue plate 121. Further, the upper and lower convex connection grooves 16 of the metal casing 92 are respectively provided with two elastic buckles 131.

The height of the connecting groove 16 of the type A standard USB2.0 electrical connection base 10 is 5.12 mm, the height of the tongue plate 121 is 1.84 mm, the height of the large space 162 is 2.56 mm, and the height of the small space 161 is 0.72. Mm, that is, the height of the large space 162 = the height of the small space 161 + the height of the tongue 121.
