Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 and 2, the radio frequency terminal comprises a rectangular base 1, a cylindrical socket 2 is welded on the side wall of one end of the base 1, and a limiting pipe 3 surrounding the socket 2 is further arranged on the outer side wall of the base 1. Spacing pipe 3 is provided with external screw thread 8 towards the one end of base 1, and threaded connection is realized through external screw thread 8 and base 1 to spacing pipe 3.

As shown in fig. 1 and 2, a circular blocking piece 13 with a diameter larger than that of the limiting pipe 3 is fixedly arranged on the limiting pipe 3 in a penetrating manner, the blocking piece 13 is positioned on one side of the external thread 8, and when the limiting pipe 3 is screwed on the base 1, the side wall of the blocking piece 13 is attached to the outer side wall of the base 1.

As shown in fig. 1 and 2, three fixing pieces 4 uniformly surrounding the outer side of the socket 2 are formed on one side of the limiting pipe 3 departing from the base 1, and the fixing pieces 4 have certain toughness. One end of the fixing piece 4 far away from the base 1 gradually extends along the direction of the socket 2, and the front end exceeds the front end of the socket 2. The front ends of the three fixing pieces 4 are respectively bent towards the directions far away from the socket 2 to form cambered surfaces 14, and the inner side walls of the three fixing pieces 4 and the outer side walls of the socket 2 form a limiting opening 9 together.

As shown in fig. 1 and 2, the inner side walls of the three fixing pieces 4 are fixedly connected with the fixture blocks 5 facing the socket 2, the fixture blocks 5 are located above the socket 2, and the side walls of the fixture blocks 5 are gradually bent towards the socket 2 at the lower end to form the barbs 6. The side wall of the clamping block 5 facing the socket 2 is bonded with a rubber pad 7, and the rubber pad 7 is positioned on the lower side wall of the barb 6. When the plug connection position is to move in the direction far away from the socket 2, the reverse resistance can be generated on the plug connection position through the barb 6, so that the outward movement of the plug connection position can be limited, the plug can be stably inserted into the socket 2, and the fixing effect is enhanced.

As shown in fig. 3, a circumferentially surrounding limiting piece 10 is fixedly connected to the inner side wall of the socket 2, a plurality of limiting strips 11 along the direction of the socket 2 are formed in the middle of the limiting piece 10, and the limiting strips 11 are circumferentially and uniformly distributed on the limiting piece 10. The side walls of the upper end and the lower end of the limiting strip 11 gradually protrude towards the axial lead direction of the socket 2, so that the middle part of the limiting strip 11 forms a protrusion. A movable groove 12 which is uniformly distributed and penetrates through is formed between the two adjacent limiting strips 11, and the movable groove 12 is arranged along the direction of the socket 2. When the plug is inserted into the socket 2, the plug can be restrained by the restraining strips 11 formed inside the restraining pieces 10. The outer side wall of the plug is abutted to the protruding part of the limiting strip 11, so that the plug is more stable and is not easy to separate from the socket 2.

The utility model discloses a concrete effect as follows:

when inserting the plug into socket 2 gradually, the plug connection department will move into in to spacing mouthful 9 gradually, and the aperture of spacing mouthful 9 will increase gradually this moment, and the stationary blade 4 will also grow gradually to the pressure of plug connection department lateral wall simultaneously. When the plug is completely inserted into the socket 2, the fixing sheet 4 generates inward extrusion force on the plug connection part, so that the plug connection part is limited and fixed. The clamping block 5 positioned on the inner side of the fixing sheet 4 is tightly propped against the joint of the plug, so that the stability of the plug is greatly improved. When the plug is inserted into the socket 2, the plug can be restrained by the restraining strips 11 formed inside the restraining pieces 10. The outer side wall of the plug is abutted to the protruding part of the limiting strip 11, so that the plug is more stable and is not easy to separate from the socket 2.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
