Detailed Description

Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

The embodiment is as follows: referring to fig. 1-4, the main components of the present invention are: a butt-joint cable comprises a first cable 1 and a second cable 2, wherein a buckling connection structure is arranged between the first cable 1 and the second cable 2;

the buckling connection structure includes: the device comprises a first shell 3, a second shell 4, four sealing rings 5, a connecting assembly, two mounting grooves 6 and an extrusion fixing assembly;

the first casing 3 is located first cable 1 and second cable 2 junction lower extreme, and the second casing 4 is placed in first casing 3 upper end, and four sealing washer 5 set up respectively in first casing 3 and second casing 4 both sides, and coupling assembling installs respectively in first casing 3 and second casing 4 both sides outer wall department, and two mounting grooves 6 are seted up respectively in first casing 3 and second casing 4 inner wall department, and extrusion fixing component inlays and adorns in two mounting grooves 6.

It should be noted that, when the cable fixing device is used, the worker peels off the wire sheaths of the first cable 1 and the second cable 2, then places the wire cores of the first cable 1 and the second cable 2 into the extrusion fixing component, the wire cores of the first cable 1 and the second cable 2 are fixedly connected through the extrusion fixing component, the extrusion fixing component is embedded into the two mounting grooves 6 in the first shell 3 and the second shell 4, then the first shell 3 and the second shell 4 are fixed at the joint between the first cable 1 and the second cable 2 through the connecting component, the first shell 3 is matched with the second shell 4 and fixed through the extrusion fixing component, and through the four sealing rings 5, the waterproof and insulation effects of the joint of the first cable 1 and the second cable 2 are guaranteed.
