Electric connector

Abstract

The invention provides an electric connector. A male head can be inserted into the electric connector in two directions, wherein the male head is provided with an insulation seat body and a metal shell; the metal shell is coated on the insulation seat body; and a sleeving space is formed between the metal shell and the insulation seat body. The electric connector comprises a plastic base, a tongue piece, a connection groove and two rows of first contacts; the tongue piece is protruded at the front end of the plastic base; the connection groove is arranged at the front end of the plastic base and the tongue piece is wrapped in the connection groove; when the male head is inserted into the connection groove for positioning, the tongue piece is sleeved into the sleeving space; the first contacts are respectively exposed out of two surfaces of the tongue piece; and each first contact is electrically connected with a pin which extends out of the plastic base. The electric connector is characterized in that: the male head can be inserted into the space, on the two surfaces of the tongue piece, of the connection groove in forward and reverse directions; and when the male head is inserted into the connection groove for positioning, the metal shell of the male head is not contacted with the first contacts.

Description

technical field [0001] The present invention relates to an electrical connector, in particular to an electrical connector with double-sided electrical connection. Background technique [0002] The most popular signal transmission specification for computer equipment today is the Universal Serial Bus (USB for short). Connectors, sockets and transmission lines made of this specification can make peripheral equipment connected to the computer, such as a mouse, keyboard, etc., real-time Measured by computer and used immediately. [0003] Currently there are two specifications of USB 2.0 and 3.0, please refer to figure 1 , is the existing USB2.0 male head 90, which is provided with a plastic seat body 91 and a metal shell 92, the metal shell 92 covers the plastic seat body 91, and a metal shell 92 and the plastic seat body 91 form a Socket space 93, the plastic seat body 91 is only provided with a row of contacts 94 exposed in the socket space 93, the current specification of t...

Problems solved by technology

[0010] Known USB sockets, no matter 2.0 or 3.0, cannot be plugged in two directions due to the contact type on only one side. It is necessary to overcome that the USB male plug can be positioned in both directions and the four terminals 87 cannot be short-circuited. When the USB male plug is inserted, if its metal shell touches the contact 88 of the terminal 87 on one side of the tongue, it will cause a short circuit and damage the USB socket. Due to the above The potential problems of the industry make it difficult to commercialize the product due to the insurmountable technical bottleneck in the development of this product
