Detailed Description

In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the accompanying drawings.

Referring to fig. 1 to 5, the present embodiment provides a radio frequency coaxial connector, including: connector body 1, snap ring 2 and flange 3. The snap ring 2 is arranged between the connector body 1 and the mounting surface of the flange 3.

Specifically, first, the connector body 1 is provided, and the connector body 1 may be any one of the connector bodies 1 of the conventional art, and the present embodiment exemplifies a case where the inner conductor 6 is supported and fixed by the first insulator 4 and the second insulator 5 in the connector body 1.

For the connector body 1 in any mature means in the prior art, an annular limiting groove 11 is concavely formed on the outer side wall of the shell of the connector body 1; specifically, the annular limiting groove 11 is prefabricated on the outer side wall of the matching part of the connector body 1 and the flange 3.

Further, in the flange 3, the flange 3 is formed with an inner hole for fitting the connector body 1, and a positioning groove 31 corresponding to the annular stopper groove 11 is formed in the inner hole. With the connector body 1 and the flange 3 fitted in place, the positioning groove 31 communicates with the annular stopper groove 11 to collectively form an annular housing section for housing the snap ring 2.

Next, the snap ring 2 is described, which includes an annular base 21 and an arc-shaped notch 22 formed in the annular base 21; in terms of the radial dimension of the snap ring 2, a part of the snap ring is embedded in the annular limiting groove 11, and another part of the snap ring is embedded in the positioning groove 31. It should be noted here that the ratio of the arc-shaped notch 22 to the circumferential dimension of the annular base 21 is 1/5 to 1/4. For example, but not limited to, beryllium copper may be selected as the material of the snap ring 2.

On the basis of the structure, when connector body 1 and ring flange 3 assemble, install snap ring 2 in connector body 1's annular spacing groove 11 earlier, reuse arc breach 22 on snap ring 2, make snap ring 2 micro deformation be convenient for connector body 1 and ring flange 3 assemble, and after ring flange 3 and connector body 1 installed in place, snap ring 2 then resumes initial condition, snap ring 2 is from its radial dimension this moment, part embedding is in connector body 1's annular spacing groove 11, another part is then embedding in ring flange 3's constant head tank 31. Under this kind of structure, realize connector body 1 and ring flange 3's normal running fit through snap ring 2, both can prevent that connector body 1 and ring flange 3 from breaking away from the problem appearing, effectively guarantee the stability of the structure that forms after both cooperate promptly, can utilize snap ring 2's deformability to realize both's rapid Assembly again

It should be noted that, in order to facilitate the assembly of the connector body 1 and the flange 3, in an alternative embodiment, the recessed depth of the positioning groove 31 relative to the inner hole is smaller than the recessed depth of the annular limiting groove 11 relative to the outer side wall of the housing of the connector body 1 (the recessed depth here may correspond to the radial dimensions of the annular limiting groove 11 and the positioning groove 31, respectively). For example, as shown in the drawings, the recess depth of the annular retainer groove 11 with respect to the outer side wall of the housing of the connector body 1 is twice the recess depth of the positioning groove 31 with respect to the inner hole. On the basis, after the connector body 1 and the flange plate 3 are assembled in place, when the clamping ring 2 is restored to the state of the clamping ring 2, the clamping ring 2 is in clearance fit with the radial matching surfaces of the annular limiting groove 11 and the positioning groove 31.

The axial depth of the annular retaining groove 11 is the same as the axial depth of the detent groove 31 in terms of the axial dimensions of the annular retaining groove 11 and the detent groove 31. After the connector body 1 and the flange plate 3 are assembled in place, the clamping ring 2 is restored to the state of the clamping ring 2, and the axial matching surfaces of the clamping ring 2, the annular limiting groove 11 and the positioning groove 31 are in clearance fit. Under such structure, through the clearance fit between its radial face of snap ring 2 and axial face and ring flange 3 and connector body 1, can effectively guarantee the stability of the cooperation structure that forms between connector body 1 and the ring flange 3, can not influence connector body 1 again and can rotate for ring flange 3 to avoid the phenomenon of the cable atress distortion that links to each other with connector body 1 to guarantee the stability of electric performance.

Finally, regarding the flange 3 of the present embodiment, the present embodiment is further designed as follows: the flange 3 is matched and connected with a screw 7, and an elastic gasket 8 is arranged between the cap part of the screw 7 and the flange 3. The flange plate 3 can be connected with the mounting plate 9 on the matching structure in the applicable scene in a matching mode through the screws 7, so that the mounting space can be saved, and the radio frequency coaxial connector is particularly suitable for the scene that the space is narrow and the installation is inconvenient in the intensive installation of multiple channels of the radio frequency coaxial connector.
