In another embodiment of the present invention, and referring to fig. 5-10, in addition to the above embodiment, a locking assembly is provided, which is configured to lock the second fastener 2 at the interlocking station to the first fastener 1. As a preferred technical solution, the locking assembly includes a wedge 15, a sliding member 16, a bolt 17, a limiting structure and an elastic unit 20, where the wedge 15 is fixedly connected to one side of the second fastener 2, the sliding member 16 is slidably connected to one side of the first fastener 1, the sliding direction is parallel to the axial direction of the first fastener 1, during the process that the second fastener 2 approaches the interlocking station, the sliding member 16 can be in sliding contact with and matched with the wedge 15 in the sliding stroke of the sliding member 16, the bolt 17 is in threaded connection with the first fastener 1, the axial direction of the screw is parallel to the axial direction of the first fastener 1, the bolt 17 and the sliding member 16 are rotationally and slidably connected, i.e. the bolt 17 movably passes through the sliding member 16, the limiting structure is used to limit the relative sliding between the sliding member 16 and the bolt 17 between a first position and a second position, in the first position the sliding member 16 is prevented from escaping the wedge 15, in the second position the sliding member 16 is prevented from being rotated along the second fastener 2 by the sliding unit 20 when the elastic unit is restored to deform.
As a preferred technical scheme of the embodiment, the limiting structure comprises a limiting groove 18 and a limiting ring 19, wherein the limiting groove 18 is formed in the sliding piece 16, the limiting ring 19 is fixedly connected to the bolt 17, the limiting ring 19 is movably arranged in the limiting groove 18, and the limiting ring 19 can slide and rotate in the limiting groove 18. Preferably, the elastic unit 20 is a compression spring, the compression spring is movably sleeved on the bolt 17, one end of the compression spring is abutted against the sliding piece 16, and the other end is abutted against a nut of the bolt 17.
In this embodiment, when the second fastener 2 rotates from the releasing station to the close interlocking station, one side of the wedge portion 15 presses one side of the sliding member 16, at least one of the portions of the wedge portion 15 contacting with the sliding member 16 is an arc surface or an inclined surface, so that the sliding member 16 slides to the first position against the elastic force of the elastic unit 20 to avoid the wedge portion 15, when the wedge portion 15 passes through the sliding member 16 smoothly, the elastic force of the elastic unit 20 is released, so that the sliding member 16 slides to the second position, the other side of the sliding member 16 presses the other side of the wedge portion 15, at least one of the portions of the wedge portion 15 contacting with the sliding member 16 is an arc surface or an inclined surface, thereby conveniently realizing pre-locking between the second fastener 2 and the first fastener 1, that is, pre-clamping is performed on the cable, and then the sliding member 16 slides to the direction close to the second fastener 2 through the rotating bolt 17 by the spiral driving of the limiting structure, so that the pressing force of the wedge portion 15 to the second fastener 2 is increased, the wedge portion 15 drives the second fastener 2 to rotate to the second fastener 1 continuously, and the first fastener 3 and the second fastener 4 move synchronously with the locking cable 4. The locking clamp for cables with different diameter numbers can be realized by only changing the screwing depth of the screw. The other function of the compression spring is that after the cable is locked and clamped, the cable connecting locker of the invention vibrates due to the shaking of the cable, and the compressed compression spring can weaken or even avoid loosening of the bolt 17 due to the vibration, so that the cable connecting locker can always provide enough locking force for the cable.
As a preferred embodiment of the present invention, the first fastener 1 has a connector 21, and the connector 21 is used for connecting to an insulator of a narrow-base cable terminal tower or other fixing base.

In this way, the tension of the cable on the second fastener 2 after the cable is locked and clamped will cause the second fastener 2 and the bolt 17. The limiting ring 19 has a sliding trend relative to the sliding part 16, and under the sliding contact abutting fit of the wedge-shaped part 15 and the sliding part 16, the second fastener 2 has a rotating locking trend relative to the first fastener 1, so that the cable is pulled more tightly, and the cable terminal is clamped more tightly by virtue of the tension of the cable.
