The present invention relates to a connector for inputting and outputting an external signal of a mobile communication terminal such as a mobile phone, and more particularly, to a plug connector connected to a socket connector installed in a mobile phone.

A plug connector for a mobile communication terminal such as a cellular phone usually includes a plurality of connection terminals arranged at a constant pitch, an insulator which insulates adjacent connection terminals while supporting the plurality of connection terminals at a constant pitch, and surrounds the outside of the insulator. Consists of a housing.

In such a conventional connector, when the connector is inserted into and coupled to the socket connector, the housing front end portion surrounding the insulator is inserted into the insertion hole of the socket connector such that the connection terminals of the insulator come into contact with the connection terminals of the socket connector.

Therefore, in such a structure, the plug connector has a small contact area in contact with the socket connector, so that even if only a small external force is applied to the plug connector, there is a problem that a connection occurs due to shaking or deviation from the contacting portion. Since only the part to be coupled is supported by the socket connector, the coupling part of the housing is frequently broken when an external force is applied.

Accordingly, the present invention is designed to solve the shortcomings of the conventional connector, to increase the contact coupling force with the mating coupling parts (socket connector) to prevent poor contact with the mating mating parts even if an external shock is applied, the rigidity against external impact It is an object of the present invention to provide a plug connector for a mobile phone having improved.

The present invention for achieving the above object is a plurality of contact terminals arranged at a constant pitch is inserted into the seating groove formed in the same pitch to support a portion exposed, an outer conductor cell coupled to surround the insulator from the outside, One end of the fixing end is fitted into a fixing groove formed at the edge of the insulator and the free end of the other end protrudes outward through the opening of the insulator and the outer conductor cell so as to be elastically caught in the locking groove of the socket connector and fixed to the socket connector. In the plug connector for a mobile phone consisting of a locking pin and a housing surrounding the outer conductor cell to surround the outer side,

The upper and lower outer conductor cells, which are divided so that the outer conductor cells wrap about half of the upper and lower sides of the insulator, are assembled with each other, and the outer conductor cells protrude outward in the longitudinal direction of the housing to insert the socket connector. Is inserted into the structure to be connected and supported by the socket connector.

As described above, in the present invention, a part of the outer conductor cell is inserted into and supported by an insertion hole of the socket connector, so that the coupling force is increased, so that the external conductor cell is stably connected without being separated from the socket connector even when an external shock is applied.

In the plug connector of the present invention, at least one outer conductor cell of the upper and lower outer conductor cells is formed with at least one coupling hole and is coupled with a fixing protrusion formed to protrude at a corresponding position of the insulator, thereby insulating the outer conductor cell. It is structured to fix against. Therefore, the coupling between the outer conductor cell and the insulator is firm, so that the plug connector can be maintained without being easily disassembled against external force or external impact acting when the plug connector is inserted into and removed from the socket connector.

In addition, each connection terminal of the plug connector of the present invention is provided with a bent portion in which the front end is bent to the lower side of the terminal body and bent in parallel to the body in the longitudinal direction, and the bent portion is provided with a protruding portion protruding downward from the socket connector The contact between the terminal and the terminal is improved and noise interference with the adjacent terminal is prevented by the sidewall of the insulator.
