Abstract

The utility model discloses a kind of cables to connect cable clamp structure, it include the long pipe clamp of hollow columnar structures, external screw thread is formed on the long pipe clamp outer wall, the long pipe clamp both ends offer two symmetrically arranged expansion slots respectively, expansion slot described in two groups extends respectively at distance pipe clamp center at 1/10~1/5 pipe clamp extension position, two locking nuts are bolted on long pipe clamp between expansion slot described in two groups, the tube wall that the long pipe clamp both ends are located at expansion slot either side is thickened from center to both ends.The cable connection cable clamp structure of the utility model is simple, and cable overlap joint is convenient and reliable, comes into full contact with two spliced cables lines, to increase its electric conductivity.

Description

A kind of cable connection cable clamp structure

Technical field:

The utility model relates to power circuit interconnection technique field, in particular to a kind of cable connects cable clamp structure.

Background technique:

Cable connection generally uses parallel groove clamp in power circuit, although connection structure is normally at the position for being not subject to tension Set place, but parallel groove clamp still deposits the defect for be easy to causeing absent-mindedness after running for a period of time, or using special-shaped wire clamp, cable it Between contact area it is small, electric conductivity is poor, be used for a long time or be easy to make wire clamp inside conductor to deform or absent-mindedness by high current, and It causes to burn out conducting wire.

Utility model content:

The utility model provides a kind of cable connection cable clamp structure, solves and is easy absent-mindedness in the prior art, conductive The problem of performance difference.

The technology solution of the utility model is as follows: a kind of cable connection cable clamp structure, includes hollow columnar knot The long pipe clamp of structure forms external screw thread on the long pipe clamp outer wall, and it is symmetrically arranged that the long pipe clamp both ends offer two respectively Expansion slot, expansion slot described in two groups extend respectively at distance pipe clamp center at 1/10~1/5 pipe clamp extension position, two groups of institutes State and be bolted with two locking nuts on the long pipe clamp between expansion slot, the long pipe clamp both ends be located at the tube wall of expansion slot either side by Center is thickened to both ends.

Preferably, forming position limiting convex ring at the long pipe clamp both ends outer rim.Prevent locking nut from deviating from from both ends.

Preferably, 1.5 times with a thickness of other side pipe thickness of long pipe clamp both ends side tube wall~3 times.

Preferably, being bolted with puller bolt on two locking nuts.It is fallen back after preventing locking nut screwing.

The utility model has the beneficial effects that: the cable connection cable clamp structure of the utility model is simple, cable is taken Convenient and reliable, convenient disassembly is connect, two spliced cables line lap joints are come into full contact with, tightness improves, to increase its electric conductivity Energy.

Detailed description of the invention:

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the cross-sectional view of long pipe clamp 1 in the utility model.

In figure: 1, long pipe clamp；2, expansion slot；3, locking nut.

Specific embodiment:

Cable clamp structure is connected to a kind of cable of the utility model in conjunction with attached drawing 1, is described further.

A kind of cable of the utility model connects cable clamp structure, includes the long pipe clamp 1 of hollow columnar structures, long pipe clamp External screw thread is formed on 1 outer wall, long 1 both ends of pipe clamp offer two symmetrically arranged expansion slots 2 respectively, and two groups of expansion slots 2 are distinguished It extends on the long pipe clamp 1 at 1 center of distance pipe clamp at 1/10~1/5 pipe clamp extension position, between two groups of expansion slots 2 and is spirally connected There are two locking nuts 3, the tube wall that long 1 both ends of pipe clamp are located at 2 either side of expansion slot is thickened from center to both ends.

Further, position limiting convex ring is formed at long 1 both ends outer rim of pipe clamp.

Further, 2 times with a thickness of other side pipe thickness of long 1 both ends side tube wall of pipe clamp.

Further, puller bolt is bolted on two locking nuts 3.

The working principle of the utility model is: two cables of slow-witted connection are penetrated from long 1 both ends of pipe clamp respectively and from The other end is pierced by, and two locking nuts 3 are tightened to long 1 both ends of pipe clamp respectively, and the sectional area at long 1 both ends of pipe clamp is gradually reduced, and is squeezed Pressure both threads cable comes into full contact with it, and tightness improves, and finally tightens the puller bolt on two locking nuts to prevent from locking Nut 3 is fallen back.

The above is only the preferred embodiment of the present invention, and those of ordinary skill in the art are not making creativeness The range of the utility model protection all should belong in every other embodiment obtained under the premise of labour.
