Background

The connector is also called a connector. Also known domestically as connectors and sockets, are electrical connectors in general. I.e., a device that connects two active devices, carrying a current or signal.

The basic performance of connectors can be divided into three major categories: namely mechanical, electrical and environmental properties. Another important mechanical property is the mechanical life of the connector. Mechanical life is in fact an indicator of durability, which is called mechanical operation in the national standard GB 5095. It uses one-time insertion and one-time extraction as a cycle, and uses the judgement basis of that after the specified insertion and extraction cycle the connector can normally implement its connection function (for example contact resistance value).

Detailed Description

While the present invention will be described in greater detail with reference to the drawings wherein there is shown a preferred embodiment of the invention, it is to be understood that one skilled in the art can modify the invention herein described while still achieving the advantageous results of the invention. Accordingly, the following description should be construed as broadly as possible to those skilled in the art and not as limiting the invention.

The invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. Advantages and features of the present invention will become apparent from the following description and from the claims. It is to be noted that the drawings are in a very simplified form and are not to precise scale, which is merely for the purpose of facilitating and distinctly claiming the embodiments of the present invention.

Example one

Referring to fig. 1, the tv connector includes a plug portion 100 and a wire connecting portion 200, the plug portion 100 has a plug terminal 101 at an end thereof, the wire connecting portion 200 has a terminal 201 corresponding to the plug terminal 101, the plug portion 100 and the wire connecting portion 200 are connected together and can be formed separately or integrally, preferably integrally, the plug portion 100 forms a plug passage 103 along a first central axis 102 thereof, the plug passage 103 has a plug inlet 104 and a plug outlet 105 at two ends thereof, the wire connecting portion 200 forms a wire connecting passage 203 along a second central axis 202 thereof, the wire connecting passage 203 has a wire inlet 204 and a wire outlet 205 at two ends thereof, the plug passage 103 communicates with the wire connecting passage 203 to form a cavity 301, an upper end of the cavity 301 has a downwardly extending wire connecting terminal 302, the wire connecting terminal 302 is made of an electrically conductive metal material, preferably brass, the central line of the terminal 302 coincides with the first central axis 102, the side surface of the terminal 302 is provided with a through hole 303, the central axis of the through hole 303 coincides with the second central axis 202, one end of the through hole 303 facing the wiring channel 203 is a wire inlet hole, and the other end is a wire outlet hole.

When the cable connecting device is used, a signal wire connected with a cable signal firstly passes through the wiring channel 203, enters the cavity 301 and passes through the through hole 303, a television wire plug connected with a television end passes through the plug channel 103, enters the cavity 301 and is in contact with the wiring terminal 302, and the television wire plug bends two end parts of the signal wire positioned at the through hole 303 to form stable contact so as to communicate the signal wire with the television wire for signal transmission.
