Description

Connector for communication

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication connector, and more particularly, to a communication connector having a fastening stopper of a new structure to prevent damage to components during fastening and enable stable fastening.

Generally, a pair of communication connectors interconnecting coaxial cables each have an internal conductor and an external conductor, and a coupling between the external conductor and the internal conductor is made.

At this time, a pair of communication connectors may be damaged due to an excessive fastening force, or conversely, loose coupling may be generated without precise fastening. In order to prevent the occurrence of such phenomena, And has an axial stop that allows the operator to easily recognize.

A communication connector having such an axial stop is described in detail in German Patent DE102008034583 (registered on Feb. 17, 2011, Steckverbinder sowie Steckverbindersatz).

The above German patent describes that an axial stop is formed outside the high frequency signal path created on the inner surface of the outer conductor of the pair of connectors.

The reason why the axial stop is formed only outside the high-frequency signal path is that there is a problem that the high-frequency signal can be distorted when a stop is formed inside the high-frequency signal path.

In order to form an axial stop to the outside of the outer conductor in which the high-frequency signal path is formed, the mechanical design of the connector is very limited, and the diameter of the connector itself must be increased based on the connector of the same capacity.

Also, stopping due to metal-to-metal contact may cause wear when frequent engagement and disconnection between connectors, and such wear may cause signal distortion.

In addition, in the above-mentioned patent, although a dielectric body is used as an axial stop, the dielectric body inserts a dielectric ring as a separate component, which raises a problem of increasing the number of parts and lowering the assemblability.

SUMMARY OF THE INVENTION [0008] The present invention has been made in view of the above problems, and it is an object of the present invention to provide an axial stop located inside a high-frequency signal path to further diversify the design of a connector, Connector.

Another problem to be solved by the present invention is to provide a connector for communication which can make an axial stop using a dielectric to increase the buffering effect as compared with the contact between metals and to prevent the occurrence of abrasion.

And to prevent the increase of the number of components and the deterioration of assemblability by allowing the dielectric axial stop to be formed by using essential components of the connector instead of the additional component.

According to an aspect of the present invention, there is provided a communication connector including a first connector portion including an inner conductor, an outer conductor, and an insulation portion; And a second connector portion 200 coupled to the first connector portion 100 and the second connector portion 200. The first connector portion 100 includes an inner conductor 210, an outer conductor 230, An axial stop is formed inside the outer conductor 130 of the first connector part 100 and the outer conductor 230 of the second connector part 200. [

The connector for communication according to the present invention has an effect of diversifying the connector design by providing an axial stop from the inside of the high frequency signal path so that the conventional axial direction stop is not limited to the outside of the high frequency signal path.

Further, there is an effect of preventing a complicated configuration for making an axial stop on the outside of the high-frequency signal path and an increase in the connector diameter.

Further, the present invention has the effect of increasing the buffering effect and reducing the wear rate by forming an axial stop with a dielectric.

Further, since the dielectric provided between the inner conductor and the outer conductor can be formed so as to protrude further from the outer conductor than the outer conductor, it is not necessary to add a separate component, There is an effect that can be.
