specific Embodiment 1

[0040] Such as figure 1 As shown, the trip link 5 is composed of a core rod body 2 and an insulating cladding 1 , and the insulating cladding 1 is wrapped on the outer peripheral surface of the core rod body 2 . Specifically, the insulating cladding 1 is fixedly connected to the outer peripheral surface of the core rod body 2 through a pressing process. In this embodiment, the core rod body 2 is made of laminated glass cloth board, which not only has high tensile strength, but also avoids shrinkage and deformation when cooling down, thus ensuring that the core rod body 2 and the insulating cladding 1 The shape and position tolerance in the pressing and forming process; the insulation cladding 1 is made of unsaturated polyester fiberglass molding compound material, which has good insulation performance and high temperature fluidity, so as to ensure the detachment The insulation requirements of the buckle connecting rod are convenient for it to be effectively wrapped on the out...

Embodiment 2

Embodiment 3

[0043] Embodiment 3 of the tripping rod of the present invention is different from Embodiment 1 in that the material of the core rod body is nylon, and only the tensile strength of the core rod body made of nylon material can meet the resistance of the tripping rod. Tensile strength requirements. Certainly, in other embodiments, the material of the core rod body may also be metal, and in this case, the surface of the core rod body needs to be fully covered with an insulating cladding.

[0044] Embodiment 4 of the tripping rod of the present invention is different from Embodiment 1 in that the insulating cladding is made of nylon, and at this time the insulating cladding is wrapped on the outer peripheral surface of the core rod by injection molding. Certainly, in other embodiments, the material of the insulating cladding can also be epoxy resin, and in this case, the insulating cladding is wrapped on the outer peripheral surface of the core rod body through an injection proces...

Abstract

The invention relates to a tripping connecting rod and a production process thereof. The tripping connecting rod comprises a core rod body with hinge structures at two ends and an insulating cladding wrapping the outer side of the core rod body. The insulating cladding is fixedly connected with the core rod body. Compared with the prior art that the tripping connecting rod is integrally processed and formed by one material, the tripping connecting rod is divided into two parts, namely the core rod body and the insulating cladding wrapping the outer side of the core rod body, so that the core rod body can be made of a material with higher tensile strength, and the tripping connecting rod can meet the standard of the tensile strength; in addition, the insulating cladding wrapping outside enables the tripping connecting rod to integrally meet the insulating requirement, so that long-term effective operation of the tripping connecting rod is guaranteed, and breakage accidents are avoided.

Description

technical field [0001] The invention relates to a tripping connecting rod and a production process thereof. Background technique [0002] At present, the trip link used in the load switch-fuse combination is longer in length, smaller in diameter, and requires a certain tensile strength. The material of polyester fiberglass molding compound is integrally pressed and formed, so the produced trip link cannot meet the tensile standard, resulting in frequent breakage of the trip link during use, which in turn causes the combined electrical appliance to fail. not working properly. Contents of the invention [0003] The purpose of the present invention is to provide a tripping link to solve the technical problem that the tripping link in the prior art is not strong enough and often breaks; at the same time, the purpose of the present invention is also to provide a production process for the above-mentioned tripping link . [0004] The tripping rod of the present invention adop...
