FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a partial view of a barb of the present invention;

fig. 3 is a schematic view of the assembly completion of the present invention.

In the figure: the cable comprises a middle shell 1, an outer conductor 2, a locking shell 3, an inner shell 4, an insulator 5, a screw 6, a nut 7, a press riveting area 8 and a cable 9.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.

As shown in fig. 1, the present embodiment provides a solder-free locking cable connector, including: the middle shell 1 is provided with an outer conductor 2 and a locking shell 3 at two ends respectively; the inner part of the outer conductor 2 is of a hollow structure and is used for embedding an inner conductor 4; and the cable passes through the locking shell 3 and the end of the cable is sent to the inner conductor 4 by the rotation of the screw rod sleeved outside the locking shell 3; the screw is further rotated to push the locking housing 3 to press the opening portion of the outer conductor 2 inward to lock the inner conductor 4 with the end of the cable.

In this embodiment, specifically, the locking shell and the outer conductor 2 can be opened and closed by rotating the screw rod 6, one end of the inner conductor 4 is connected with the cable 9, the other end of the inner conductor is connected with the port of the required connecting device, the connector can be assembled without welding, and meanwhile, quick disassembly and replacement can be realized, and the requirement of a specific environment is met.

In the present embodiment, specifically, an insulator 5 is disposed between the outer conductor 2 and the inner conductor 4; the insulator 5 serves to insulate the outer conductor 2 from the inner conductor 4 and provides a restraining fixation for the inner conductor 4 located in the middle of the outer conductor 2.

In the present embodiment, specifically, one end of the insulator 5 in the connecting direction with the middle housing 1 extends out of the outer conductor 2, so as to increase the overall elasticity of the cable insertion portion.

In this embodiment, specifically, the middle shell 1 and the outer conductor 2 are connected by threads, and a press riveting area 8 is provided for fixing, the thread connection mode is stable and convenient to detach, and the press riveting area 8 can enable the outer conductor 2 to realize plastic deformation, so that reliable connection is realized.

In this embodiment, specifically, the locking housing 3 and the screw 6 are installed in an interference fit manner, and the locking housing 3 and the screw 6 are tightly connected by using the tightening force obtained by the elastic deformation of the locking housing 3.
