Connector {Connector}

The present invention relates to a connector, and more particularly, to a connector which improves a connection structure of a ground wire, a braid wire and a shield can to reduce a work process and time, and also has a stable performance.

Generally, electromagnetic waves have a useful aspect such as wireless communication and radar, but they may adversely affect the operation of electronic devices. This phenomenon is referred to as EMI (Electro Magnetic Interference) phenomenon. EMI is a harmful element to the human body as well as generating noise of the electronic device. Therefore, EMI is required to reduce the EMI phenomenon.

Therefore, recently, a shield can is applied to electronic parts such as a semiconductor device mounted on an internal printed circuit board of an electronic device to shield EMI generated from the electronic parts, So that it does not affect the operation.

The shield can is usually formed in a hexahedron shape so as to cover the electronic parts.

On the other hand, a mobile terminal is a portable electronic device having at least one function of carrying out voice and video communication, inputting and outputting information, and storing data, which is portable, And a multimedia player having complicated functions such as playing a moving picture file, playing a game, receiving a broadcast, and the like.

In order to realize the complex functions of multimedia devices, various new attempts have been made in terms of hardware or software. For example, a mobile terminal can be connected to an HDTV (High Definition TeleVision) to play HD video and digital audio through an HDTV Is proposed.

In order to implement such a system, a connector for connecting a mobile terminal and an HDTV is used. Various attempts have been made not only to function as connectors but also to implement various functions and to have an improved structure. In recent years, connectors of the USB specification have been widely used.

Since the connector is provided with a wire for connection to an external device, electromagnetic waves are generated. Therefore, a shield can is also applied to the connector for electromagnetic wave prevention.

Here, in order to facilitate electrical contact of the connector, a technique of connecting a ground wire to the shield can of the connector has been disclosed.
