Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1 and Fig. 2, the utility model cable T-type branch joint includes tail pipe 1, stress cone 2, insulating body 3, T
Type conductive sleeve 4, protection shell 5, cone support 7 bore support 7 and spring composition spring cone support.
Specifically, insulating body 3 is placed in protection shell 5, the equal shape in bottom end at the transverse arm both ends and vertical arm of T-type conductive sleeve 4
At there is jack；Fixation is embedded T-type conductive sleeve 4 in insulating body 3, for the docking between cable conductor.
Insulating body 3 after positioning internal T-type conductive sleeve 4, is integrally poured in casting by epoxide resin material
Injection forming, and be formed with and be connected to inner hole with each jack of T-type conductive sleeve 4 one-to-one correspondence, it forms in inner hole and cooperates with stress cone 2
Inner conical surface, guarantee the globality of connector.
In the Butt Assembling of cable, the core decortication of cable end is docked, then by the connect-disconnect plug of metal material
It is fixed on the core of cable end, the docking cable of connect-disconnect plug is set from the respectively end insertion of insulating body 3, until connect-disconnect plug is whole
It inserts in the jack inside T-type conductive sleeve 4, keeps to be abutted against between the outer wall of connect-disconnect plug and the jack inner wall of T-type conductive sleeve 4
Touching (matching connection).
It should be noted that reduce contact resistance, the material of connect-disconnect plug, T-type conductive sleeve 4 and cable core should keep one
It causes, if connect-disconnect plug can be copper material, for connecting copper core cable, is also possible to aluminium material, for connecting aluminium cable.
Successively assemblage stress bores 2 and tail pipe 1, the wherein protection of tail pipe 1 and insulating body 3 on the cable of close end core
