Fig. 2 is a partially enlarged view of a portion a in fig. 1.

In the figure: the cable comprises a conductor 1, a connecting part 2, a 3L-shaped bracket, a 301 horizontal section, a 302 vertical section, a 4 pipe sleeve, a 5 elastic rubber layer, a 6 annular groove, a 7U-shaped clamp and an 8 string.

Detailed Description

The technical solution of the present application will be further described and explained with reference to the accompanying drawings and embodiments.

As shown in fig. 1-2, a connection harness for preventing pulling is provided, which comprises a wire 1 with a circular cross section, wherein one end of the wire 1 is connected with a male connector, the other end of the wire 1 is connected with a female connector, the male connector and the female connector are connected with L-shaped brackets 3 through connecting components 2, horizontal sections 301 of the L-shaped brackets 3 are attached to the wire 1, the horizontal sections 301 of the L-shaped brackets 3 attached to the wire 1 are enclosed to form an annular structure, external threads are arranged on the outer surfaces of the horizontal sections 301 of the L-shaped brackets 3, two independent pipe sleeves 4 are sleeved on the wire 1, and internal threads screwed with the corresponding external threads are arranged on the inner walls of the pipe sleeves 4.
