When the self-locking radio frequency coaxial connector designed by the utility model is actually used, the male end A and the female end B of the self-locking radio frequency coaxial connector can be connected together by utilizing the threaded connection of the connecting threaded sleeve 1 and the female end conductor. And, the end of the male end A connecting screw sleeve 1 near the female end B is also provided with at least one fixing lug 11, and one side of the female end B housing 9 near the male end A is correspondingly provided with at least one groove 91, when the fixing lug 11 on the male end A connecting screw sleeve 1 is screwed into the groove 91 of the female end B housing 9, the designed connecting screw sleeve 1 can be locked by the housing 9, thereby achieving the self-locking effect.
It should be noted that, in order to ensure that the male end a and the female end B do not loose after the self-locking connection, the inventor has optimally designed the matching of the housing 9 of the female end B and the female end conductor, when designed, the housing 9 can be sleeved on the female end conductor and is arranged to be movable in the axial direction of the female end conductor without rotating in relation to the radial direction of the female end conductor. Therefore, under severe vibration use environment, the self-locking radio frequency coaxial connector designed by the utility model cannot loosen after being butted, the connecting screw sleeve 1 cannot radially rotate any more, and the signal transmission cannot generate jumping phenomenon.
Moreover, as shown in fig. 3, when an operator needs to unlock the self-locking radio frequency coaxial connector, the outer shell 9 of the female end B is pulled towards a direction away from the male end a connecting screw sleeve 1, so that the outer shell 9 of the female end a can move towards a direction away from the connecting screw sleeve 1 along an axial direction of the female end conductor, a gap is formed between the male end a connecting screw sleeve 1 and the outer shell 9 of the female end B, and then the operator rotates the male end a connecting screw sleeve 1 to unlock the threaded connection between the connecting screw sleeve 1 and the female end conductor, so that the male end a and the female end B can be separated.

Further, a spring 8 and a compression ring 10 are also arranged in the shell 9; wherein the compression ring 10 is fastened outside the female end conductor to be in interference fit with the female end conductor; one side of the spring 8 abuts against the housing 9, and the other side of the spring 8 abuts against the pressure ring 10.
In the utility model, in order to prevent the female end B shell 9 from loosening in the axial direction under severe vibration use environment and prevent the shell 9 from loosening in butt joint with the connecting screw sleeve 1, the inventor further arranges a spring 8 and a compression ring 10 in the shell 9.

One end of the spring 8 arranged in the shell 9 is abutted against the shell 9, and the other end is abutted against the compression ring 10 fixedly matched with the female end outer conductor 5.
Since the compression ring 10 is fixedly matched with the female end outer conductor 5 and the spring 8 has elastic force, as shown in fig. 2, under the action of the elastic force of the spring 8, the outer shell 9 can be tightly abutted against the raised step 53 (see fig. 2 and 7) of the female end outer conductor 5 in a normal state, and the raised step 53 can block the outer shell 9 to avoid further displacement of the outer shell 9. And after the shell 9 is connected with the connecting screw sleeve 1, the elasticity of the spring 8 is used as a pretightening force, so that the groove 91 of the shell 9 is tightly aligned with the fixing lug 11 of the connecting screw sleeve 1, and the groove 91 and the fixing lug 11 are prevented from loosening under severe vibration conditions.
It should be noted that, since the spring 8 is installed inside the housing 9, when an operator needs to unlock the self-locking rf coaxial connector, the housing 9 is only controlled to overcome the elastic force of the spring 8 and move along the axial direction of the female end outer conductor 5 in the direction away from the connection screw sleeve 1, so as to release the matching between the groove 91 and the fixing bump 11, and rotate the connection screw sleeve 1 of the male end a to unlock the threaded connection, thereby separating the male end a from the female end B.

By this arrangement, radial rotation of the housing 9 compared to the female end conductor can be restricted so that the housing 9 can only move axially.
Example 1
Referring to fig. 1 to 7, a first embodiment of the present utility model is as follows: a self-locking radio frequency coaxial connector, comprising: a male end A and a female end B. In this embodiment, the male end a is composed of a connecting screw sleeve 1, a male end insulator 2, a male end inner conductor 3 and a male end outer conductor 4, and the female end B is composed of a female end outer conductor 5, a female end insulator 6, a female end inner conductor 7 and a housing 9.
The male end insulator 2 of the male end A is arranged between the male end inner conductor 3 and the male end outer conductor 4 and forms a fixed whole, and the connecting screw sleeve 1 is correspondingly sleeved on the male end outer conductor 4 and can rotate in the radial direction of the male end outer conductor 4; the female insulator 6 of the female terminal B is correspondingly disposed between the female outer conductor 5 and the female inner conductor 7, and forms a fixed whole, and the housing 9 is correspondingly sleeved on the female outer conductor 5 and can move along the axial direction of the female outer conductor 5 without rotating in comparison with the radial direction of the female outer conductor 5.
It should be noted that, in the embodiment, in order to simplify the threaded connection of the male end a and the female end B for the convenience of the operator, the inventor provides the male screw 51 on the female end outer conductor 5 (as shown in fig. 7) and the female screw 12 on the connection screw 1 (as shown in fig. 4). Based on the arrangement, in actual connection, an operator only needs to control the connecting screw sleeve 1 of the male end A and align the connecting screw sleeve with the female end outer conductor 5 of the female end B, then control the internal thread 12 of the connecting screw sleeve 1 to match with the external thread 51 of the female end outer conductor 5, and screw the connecting bolt 1, so that the threaded connection of the male end A and the female end B can be realized.
Correspondingly, as can be seen further from fig. 4, 5 and 6, in the present embodiment, two fixing protrusions 11 are further provided on the connecting screw sleeve 1 of the male end a, the fixing protrusions 11 are specifically designed as protruding ribs, and four corresponding grooves 91 are provided on one side of the housing 9 of the female end B near the male end a. Wherein, the fixing lug 11 designed can be correspondingly matched with the groove 91, and when the connecting bolt 1 is screwed to realize the threaded connection fixation of the male end A and the female end B, an operator is required to further control the matching of the fixing lug 11 of the connecting bolt 1 and the groove 91 of the shell 9 so as to lock the connecting bolt 1 and the shell 9 together. Since, during design, the inventor purposely designed that the housing 9 can only move along the axial direction of the female-end outer conductor 5, and does not rotate in the radial direction compared with the female-end outer conductor 5, the radial rotation of the connecting bolt 1 can be effectively limited by utilizing the self-locking of the housing 9 and the connecting bolt 1.
It should be noted that, in the self-locking rf coaxial connector according to the present utility model, the radial rotation of the housing 9 compared to the female end outer conductor 5 is limited. A limiting portion 52 (as shown in fig. 7) is further specifically disposed on the female end outer conductor 5, and a limiting cavity 91 (as shown in fig. 4 and 5) is required to be correspondingly disposed in the housing 9, so as to limit radial rotation of the housing 9 compared with the female end conductor based on matching of the limiting portion 52 and the limiting cavity 92. As shown in fig. 4 and 7, in the present embodiment, the limit cavity 92 on the housing 9 is specifically set to a first rectangle, and at the same time, the cross section of the corresponding limit portion 52 is set to a second rectangle corresponding to the first rectangle. By this arrangement, radial rotation of the housing 9 compared to the female end conductor can be restricted so that the housing 9 can only move axially.
In addition, as can be seen from further reference to fig. 2 and 3, in the present embodiment, in order to avoid the loosening of the female end B housing 9 of the self-locking rf coaxial connector designed in the present utility model in the axial direction and the loosening of the locking of the connection screw sleeve 1 with the male end a in the severe vibration use environment, the inventor further sets the spring 8 and the compression ring 10 in the housing 9.
As shown in fig. 2 and 3, in the present utility model, a pressing ring 10 provided inside a housing 9 is fastened outside a female-end outer conductor 5 of a female-end conductor, and the pressing ring 10 can be interference-fitted with the female-end outer conductor 5 to fix itself with the female-end outer conductor 5. One end of the spring 8 arranged in the shell 9 is abutted against the shell 9, and the other end is abutted against the compression ring 10 fixedly matched with the female end outer conductor 5.
Since the compression ring 10 is fixedly matched with the female end outer conductor 5 and the spring 8 has elastic force, as shown in fig. 2, under the action of the elastic force of the spring 8, the housing 9 can be tightly abutted against the raised step 53 (see fig. 2 and 7) of the female end outer conductor 5 in a normal state, and the raised step 53 can block the housing 9 to avoid further displacement of the housing 9. In this way, after the housing 9 and the connecting screw sleeve 1 are locked in a butt joint, the elastic force of the spring 8 is used as a pretightening force by utilizing the characteristic of the spring 8, so that the groove 91 of the housing 9 can be tightly aligned with the fixing projection 11, and the groove 91 and the fixing projection 11 can be prevented from loosening under severe vibration conditions.
It should be noted that, since the spring 8 is installed inside the housing 9, when an operator needs to unlock the self-locking rf coaxial connector, the housing 9 is only controlled to overcome the elastic force of the spring 8 and move along the axial direction of the female end outer conductor 5 in the direction away from the connection screw sleeve 1, so as to release the matching between the groove 91 and the fixing bump 11, and rotate the connection screw sleeve 1 of the male end a to unlock the threaded connection, thereby separating the male end a from the female end B.
In the practical use process, the male end A and the female end B of the self-locking radio frequency coaxial connector are connected through threads, meanwhile, the fixing lug 11 designed at the end part of one side of the connecting screw sleeve 1 of the male end A, which is close to the female end B, can be matched with the groove 91 correspondingly formed in one side of the shell 9, which is close to the male end A, so that when the connecting screw sleeve 1 of the male end A is in threaded connection with the female end outer conductor 5 of the female end B, the fixing lug 11 on the connecting screw sleeve 1 can be correspondingly screwed into the groove 91 of the shell 9. Since the housing 9 can be fitted over the female-end outer conductor 5 in design, it is provided so as to be movable in the axial direction of the female-end outer conductor 5 without rotating in comparison with the radial direction of the female-end outer conductor 5. Therefore, under severe vibration use environment, the self-locking radio frequency coaxial connector designed by the utility model cannot loosen after being butted, and the shell 9 designed by the female end B can lock the connecting screw sleeve 1 and limit and lock radial rotation of the connecting screw thread 1, so that the signal transmission cannot generate jumping phenomenon.
When an operator needs to unlock the self-locking radio frequency coaxial connector, only the shell 9 of the female end B needs to be pulled towards the direction away from the male end A connecting screw sleeve 1, so that the shell 9 of the female end A moves towards the direction away from the connecting screw sleeve 1 along the axial direction of the female end outer conductor 5, and further a gap is formed between the male end A connecting screw sleeve 1 and the shell 9 of the female end B, and the radial rotation of the connecting screw sleeve 1 is not locked by the shell 9. Then an operator can rotate the connecting screw sleeve 1 of the male end A to unlock the threaded connection of the connecting screw sleeve 1 and the female end outer conductor 5, and the male end A and the female end B can be separated.
Therefore, in the actual use process, the self-locking radio frequency coaxial connector designed by the utility model can effectively, quickly and conveniently realize self-locking connection of the male end and the female end, and the male end and the female end of the self-locking radio frequency coaxial connector cannot loosen after being butted under severe vibration use environment, so that the signal transmission cannot generate a jumping phenomenon, the stability is better, and the self-locking radio frequency coaxial connector has good popularization prospect and application value.
The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent changes made by the specification and drawings of the present utility model, or direct or indirect application in the relevant art, are included in the scope of the present utility model.
