In the annular groove on the A outer conductor, the screw sleeve slides on the B outer conductor in the axial direction, and its rib-shaped elastic bayonet is buckled with the first annular groove to realize the axial locking of the plug and the socket.

There are several A sectional grooves and B sectional grooves arranged axially. the

Compared with the prior art, the present invention has the advantages of axial locking function, simple structure, low manufacturing cost, and convenient operation. Once locked, pulling the cable or any other part will not disconnect it, and the connection reliability is high. Widely used in radio equipment and instruments, especially suitable for use on small and ultra-small electrical connectors where multiple products are installed on one panel at the same time and are installed in high density, ensuring good mechanical and electrical performance.

Detailed ways

Referring to accompanying drawing 1, the present invention is made up of socket 1 and plug 2, and socket 1 is made up of A outer conductor 11, A insulator 12, A inner conductor 13 and A interface 14 and is formed, and plug 2 is made of B outer conductor 21, B insulator 22 , B inner conductor 23, B interface 24 and screw sleeve 25 are packaged, and the screw sleeve 25 is a bushing with ribbed elastic bayonet 26 and A cut groove 27 at one end, and a tapered nozzle 29 at the other end. A sectional grooves 27 are several and arranged axially; B outer conductor 21 is a sleeve with elastic claws 31 and B sectional grooves 30 at one end, and a first annular groove 28 and a second annular groove 32 at the other end. The B sectional grooves 30 are several and arranged in the axial direction; the A outer conductor 11 is a stepped shaft sleeve provided with an annular slot 16, and its port is provided with a groove 15; the screw sleeve 25 is set with the B outer conductor 21, and its ribbed The elastic bayonet 26 is fastened to the second annular groove 32; the plug 2 is plugged into the socket 1 in the axial direction, and the elastic claw 31 on the B outer conductor 21 is buckled to the annular groove 16 on the A outer conductor 11, The screw sleeve 25 slides on the B outer conductor 21 in the axial direction, and its rib-shaped elastic bayonet 26 slides into the first annular groove 28, and the convex rib-shaped elastic bayonet 26 is buckled with the first annular groove 28 to realize Axial locking of plug 2 and socket 1.

Referring to accompanying drawings 2 to 4, the plug 2 is made up of B outer conductor 21, B insulator 22, B inner conductor 23, B interface 24 and screw sleeve 25 as concentric circles. Elastic bayonet 26 and A cut-away groove 27, the other end is provided with a sleeve with tapered nozzle 29, A cut-away groove 27 is several and axially arranged; B outer conductor 21 is provided with elastic claw 31 and B cut-away groove 30, the other end is provided with the sleeve of the first annular groove 28 and the second annular groove 32, the B sectional groove 30 is several and axially arranged, and the rib-shaped elastic bayonet 26 at one end of the screw sleeve 25 is clamped on the B Inside the second annular groove 32 on the outer conductor 21 . The B outer conductor 21 adopts a copper alloy claw structure with elastic claws 31 and B slits 30, which has good elastic recovery capability; the screw sleeve 25 adopts claws with ribbed elastic bayonets 26 and A slits 27 The structure is made of elastic copper alloy or plastic material, which also has good elastic recovery ability. The tapered nozzle 29 at the port of the screw sleeve 25 is convenient for the elastic claw 31 on the B outer conductor 21 and the claw piece structure of the B sectional groove 30 to expand.

Referring to accompanying drawings 5 to 7, the socket 1 is composed of an A outer conductor 11, an A insulator 12, an A inner conductor 13 and an A interface 14 as concentric circles, and the A outer conductor 11 is a stepped shape with an annular slot 16 The shaft sleeve is provided with a groove 15 at its port, and the groove 15 is convenient for guiding the insertion of the B outer conductor 21 of the plug 2 . the
