Nut crimping is usually used in the thicker conducting wire connection of line footpath, i.e., conducting wire or threading nose is put into nut and terminals
Between, conducting wire or threading nose are compressed by tightening nut.
Existing screw crimping, there are following technical problems:
1, not tight long-term vibration conducting wire is crimped to be easy to fall off.
2, screw corrosion is difficult to replace under long-term outdoor or wet environment.
3, nut crimping installation quality is difficult to control, and conductor part is cut crimp for convenience by worker, is caused
The current-carrying capacity of conducting wire is inadequate, and high current, which flows through, to be easy to burn line.
4, conducting wire pressure nose needs specific purpose tool, is unfavorable for accident rapid rush-repair.
Utility model content
The purpose of this utility model is to provide a kind of crimping screws, and to solve now, there are two types of existing for screw crimping structure
Technical problem.The utility model can be not only fixedly secured conducting wire but also can have been corroded in screw by the pattern of change conventional screw
In the case of screw easy to disassemble.
To achieve the goals above, the utility model adopts the following technical solution:
A kind of crimping screw, comprising:
Screw；The screw includes square spigot and threaded rod, has round conductor hole among square spigot, for putting conducting wire；
Threaded rod is connected to the side wall of square spigot；
Nut, for fixing conducting wire and terminals with shaft.
Further, the extending direction of threaded rod is vertical with the extending direction in round conductor hole.
Further, round conductor hole inner wall has screw thread.
Further, terminals have square mounting hole.
Further, when installation condition, conducting wire passes through round conductor hole, and the square spigot of screw inserts in the rectangular peace of terminals
It fills in hole；Nut is tightened on threaded rod, fixes conducting wire with terminals.
Further, square spigot be parallel to conducting wire extend put to two sides and the gap of square mounting hole 30 be A, it is rectangular
Head extend perpendicular to conducting wire put to two sides and the gap of square mounting hole 30 be B；A < B.
Further, A=0.2mm；B=1.5mm.
Further, gasket is equipped between nut and terminals, gasket covers on threaded rod.
It further, is square hole among gasket, the size of square hole is greater than the rectangular area of bed of screw, can be for rectangular
Head is passed through from square hole.
Further, the gasket between nut and terminals is a piece of or multi-disc.
Compared with the existing technology, the utility model has the following beneficial effects:
1), pressuring line structure fixation, conducting wire are not easy to loosen；
2), screw corrosion seriously remains to be convenient for changing；
3), mounting process is simple, and installation effectiveness is high；
4), without crimping threading nose in conductor wire end, streamline operation is convenient for accident rapid rush-repair；
5) it is big to adapt to wire range for, low manufacture cost.

Specific embodiment
The utility model will be described in detail below with reference to the accompanying drawings and embodiments.It should be noted that not conflicting
In the case where, the features in the embodiments and the embodiments of the present application can be combined with each other.
Following detailed description is exemplary explanation, it is intended to provide further be described in detail to the utility model.It removes
Non- otherwise indicated, all technical terms used by the utility model are usual with the application one of ordinary skill in the art's
The meaning of understanding is identical.Term used in the utility model is merely to describe specific embodiment, and be not intended to limit
Illustrative embodiments according to the present utility model.
It please refers to shown in Fig. 2 and Fig. 3, a kind of crimping screw of the utility model, including screw 1, nut 4 and gasket 5.
