As shown in FIGS. 3 and 4, the coaxial connector of the present invention comprises a housing 100 formed in a cylindrical shape, a cylindrical outer conductor connection part 200 provided inside the housing 100, A center conductor connection part 400 provided inside the external conductor connection part 200 and an insulator 300 provided between the external conductor connection part 200 and the central conductor connection part 400.

The outer conductor connection part 200 and the central conductor connection part 400 are electrically connected to each other. The outer conductor connection part 200 is electrically connected to an outer conductor provided outside the coaxial cable, The central conductor connection part 400 is electrically connected to the core conductor provided at the center of the coaxial cable.

The insulator 300 is provided between the outer conductor connection part 200 and the central conductor connection part 400 so that the outer conductor connection part 200 and the central conductor connection part 400 are electrically insulated from each other.

The insulator 300 is formed in a cylindrical shape. The insulator 300 has a receiving groove 310 formed in the circumferential direction along the circumferential direction. The receiving groove 310 is provided with a ring-shaped packing 320.

The packing 320 inserted in the receiving groove 310 is in close contact with the inner circumferential surface of the outer conductor connecting portion 200 so that the insulator 300 is prevented from moving arbitrarily, and the outer conductor connecting portion 200, Thereby preventing moisture or foreign matter from entering through the gap that can be formed between the first electrode 300 and the second electrode 300.

The first stepped portion 110 is formed at the front end of the inner circumferential surface of the housing 100 to form a space with the outer conductor connecting portion 200 so that the outer conductor connecting portion of the connector, (Not shown) are inserted, so that they are stably connected.

A second step 120 is formed at a rear end of the inner circumference of the housing 100. The outer conductor connecting part 200 is formed in a cylindrical shape and the second step is formed along the outer circumferential surface of the second step 120 The third step 230 is formed so as to correspond to the third step.

When the external conductor connection part 200 is inserted into the housing 100, the third step part 220 is inserted into the second step part 120, So that it does not protrude all over the housing 100.

A cutout 210 is formed in the front end of the external conductor connection part 200 in the longitudinal direction at regular intervals along the circumferential direction. The front end of the cutout part 210 is bent outward.

When the external conductor connection part 200 is inserted into the housing 100, the bending part presses the inner circumferential surface of the housing 100 by the elastic force pressing the external part, The housing 100 is firmly coupled to the inside of the housing 100, so that it can be prevented from arbitrarily moving even if an external force is applied.

In addition, in order to prevent the inner housing 20 from rotating as shown in FIG. 1, the pin 16 must be inserted with a separate pin 16, which complicates the structure and complicates the process. In the present invention, since the assembly is performed only by inserting the external conductor connection part 200 into the housing 100, the structure can be simplified and the manufacturing cost can be reduced.

The outer circumferential surface of the end portion of the outer conductor connection portion 200 where the cutout portion 210 is formed is tapered.

Therefore, when the external conductor connection part 200 is inserted into the housing 100, the external conductor connection part 200 is inserted through the rear end of the housing 100 and inserted into the housing 100 more easily by the tapered part. .

Meanwhile, the housing 100 is made of a metal material, and aluminum can be used to reduce the overall weight.

Herein, the surface of the housing 100 is coated with a hard anodizing method to improve durability and corrosion resistance, and damage can be prevented even for a long period of time, and various colors can be formed through hard anodizing, Thereby enhancing external aesthetics.

At this time, a coupling ring 500, which is formed in a sleeve shape, is inserted into the mounting groove 140. In the space formed by the coupling ring 500 and the first step 110, An external conductor connection portion (not shown) of a connector to be connected is inserted and electrically connected.

In this way, the outer conductor connection part 200 can be stably connected to the outer conductor connection part (not shown) of another connector even if the outer conductor connection part 200 is not provided inside the housing 100 ' It is possible to stably prevent the coaxial cable from being damaged by the movement of the external conductor connection part 200 arbitrarily.

Further, since the coupling ring 500 is simply inserted and fixed to the front end of the housing 100 'as compared with the process of coupling the outer conductor connection part 200 to the housing 100', the structure is simple and easy to assemble The manufacturing cost can be significantly reduced.

The coupling ring 500 may be formed in a simple sleeve shape so as to prevent interference with the housing 100 'and to form a locking protrusion 510 on the outer peripheral surface of the rear portion of the coupling ring 500, The coupling ring 500 is firmly coupled to the housing 100 'so that the housing 100' can be freely moved even if an external force acts on the coupling ring 500. As a result, As shown in FIG.

As shown in FIG. 7, the engaging rings 500 are formed at regular intervals along the circumferential direction, and the ends where the cutouts 520 are formed are bent outward, The inner circumferential surface of the mounting groove 140 of the housing 100 'is pressed by the resilient force to be pressed and firmly fixed.

Meanwhile, the remaining components are the same as those described above, so a detailed description thereof will be omitted.

While the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the scope of the present invention is not limited to the disclosed embodiments, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
