Description

Connector pressurization apparatus for coaxial cable

The present invention relates to a crimping connector for a coaxial cable, and more specifically, to coaxial cable fastening and connecting the connector to the coaxial cable more quickly and easily by catching one end of the connector inserted into one end and pressing the other end. The present invention relates to a connector crimp for a coaxial cable.

In general, a coaxial cable has internal and external insulators, and a mesh-shaped external conductor is wired between the internal and external insulators, and an internal conductor is wired at the center of the internal insulator.

When the coaxial cable is to be connected to, for example, a television, it is connected using a connector. The connector includes a fixing body, a pressing body, a connecting body, and a rotating body.

The fixture is formed in a cylindrical shape having a tapered inclined surface at one end of the inner circumferential surface, and the pressing body pressurizes the outer insulator of the coaxial cable as it is inserted into the fixing body and prevents from being released from the fixing body. The locking projection is formed to protrude.

In addition, the connector is inserted into the pressing body, the center portion is penetrated to penetrate the inner insulator of the coaxial cable to the center portion, and one end of the locking jaw is formed to be caught by the rotating body, and the rotating body is the locking jaw of the connecting body. It is rotatably connected to the inner peripheral surface is formed with a screw for screwing.

When connecting the connector made as described above to the coaxial cable as shown in Figures 1a and 1b is inserted into the opposite side of the rotor 21 of the connector 20, the connector ( 20) Fix it to the fixing tool for fixing.

When the connector 20 is fixed by the fixing tool, and the connector 20 is seated on the pressure device, and the pressure tool is pressed, the pressure body 22 is fixed as shown in FIG. 1B. 23, the inner circumferential surface of the fixing body 23 is pressed by the pressing protrusion 22a while being moved inwardly, and the end thereof is reduced by the inclined surface 23a of the fixing body 23, and thus the coaxial cable 10 The outer insulator 11 of) is fixed.

At this time, the inner conductor 13 provided in the center portion of the inner insulator 12 of the coaxial cable 10 passes through the connecting body 24 and the rotating body 21 rotatably connected to the connecting body 24.

That is, when the connector 20 is fixed to the fixing tool, and then the rotary body 21 of the connector 20 is pressed using a pressurizing tool, the press body 22 moves to the inside of the fixing body 23. The connection with the coaxial cable 10 is completed.

However, when the connector is to be connected to the coaxial cable as described above, the worker can fasten the connector to which the coaxial cable is connected by using a fixing tool, and then press the fixed connector with a pressure tool to press the connector. Not only can not be made but there was a problem that the resulting productivity is lowered.

In addition, there is a problem that a lot of failure rate is generated by connecting the connector to the coaxial cable by using the fixing tool and the pressure tool.

The present invention has been devised to solve the above problems, and after inserting and seating the connector into which the coaxial cable is inserted inward, the pressurizing handle member is connected to the rear end of the body part in a rotatable manner. According to the movable member to make the fixed connection of the coaxial cable according to the pressing of the connector by the movement to make the connection between the coaxial cable and the connector more quickly and conveniently, and thereby to improve the productivity, It is an object of the present invention to provide a coaxial cable connector crimp that can be easily inserted and withdrawn due to the fixing member provided in the body portion to minimize the defect rate.
