Abstract
The invention relates to a virtual connection preventing wiring terminal, and belongs to the field of electrical elements. The virtual connection preventing wiring terminal comprises a wiring end, wherein a thread structure is arranged on the outer wall of the wiring end; one end of the wiring end is fixedly connected with a U-shaped end; the U-shaped end comprises two contact surfaces; a U-shaped groove is formed between the two contact surfaces; a screw hole is formed in one side of each contact surface; a fastening screw is correspondingly connected with each screw hole separately; and one end of each fastening screw is connected with a nut. Due to the two contact surfaces and the U-shaped groove, the contact area is enlarged, heat dissipation is improved, and the loosening of the connecting point caused by heat expansion and cold contraction is reduced; meanwhile, due to the two screw holes, the wiring terminal can be reliably fixed on equipment, so that loosening can be more effectively prevented; and in addition, the U-shaped end has certain mechanical elasticity, so that loosening of the terminal can be also prevented.
Description
Technical field
The present invention relates to a kind of anti-virtual connection binding post, belong to electrical equipment field.
Background technology
Binding post is to apply to facilitate the connection of wire, it is exactly one section of sheet metal being enclosed in inside ambroin in fact, two ends are all porose may be inserted into wire, there is screw for fastening or unclamping, such as two wires, sometimes for connection, sometimes need again to disconnect, at this moment just with terminal, they can be coupled together, and can disconnect at any time, without they being welded or being intertwined, easily quick, and it is suitable for substantial amounts of wire interconnection, special terminal block is just had in power industry, terminal box, it is binding post above entirely, monolayer, double-deck, electric current, voltage, common, can break etc., certain compression joint area is to ensure that reliable contacts, and guarantee by enough electric currents.
The common critical failure form of binding post has following three kinds:
1. loose contact, metallic conductor within binding post is the core part of terminal, it is by the voltage from external cable or cable, electric current or signal are delivered on the contact that associated adapter is corresponding, therefore contact must possess excellent structure, reliable and stable contact retention and good electric conductivity, owing to contact piece structure design is unreasonable, material selection mistake, mould is unstable, processing dimension is overproof, rough surface, the process of surface treatment such as heat treatment plating are unreasonable, it is improper to assemble, storage use bad environments and operate with improper, loose contact is caused in the contact site of contact and matching part in capital.
2. defective insulation, the effect of insulator is to make contact keep correct position to arrange, and make between contact and contact, mutually insulated between contact and housing, therefore insulating part must possess excellent electric property, mechanical performance and technological forming performance, owing to insulator surface or inside exist metal fifth wheel, surface dust, solder flux etc. pollute and make moist, organic material precipitate and harmful gas adsorbed film merge with surface moisture film and form ionic conductive channel, the moisture absorption, mildew, the reasons such as insulant is aging, short circuit is caused in capital, electric leakage, puncture, the defective insulation phenomenons such as insulation resistance is low.
3. fixing bad; insulator not only plays insulating effect; generally also the contact for stretching out provides accurate to neutralizing protection; also there is installation location simultaneously; be locked the function on equipment; fixing bad; the lighter affects contact and reliably causes instant cut-off; serious is exactly that product disintegrates, and disintegrates and refers to that binding post is under plugging together state, due to material; design; the reasons such as technique cause between the unreliable plug caused of structure and socket, and abnormal between contact pin with jack separates, and will result in and control system power transmission and signal controls the serious consequence interrupted.Unreliable owing to designing, selection mistake, the processing qualities such as it is improper that moulding process selects, heat treatment, mould, assembling, welding are poor, assemble grade not in place and all can cause fixing bad.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, a kind of anti-virtual connection binding post is provided, by arranging two contact surfaces and U-lag, increase contact area, increase heat radiation, what decrease that junction point causes owing to expanding with heat and contract with cold loosens, simultaneously because be provided with two screws, this binding post is made to be fixed to reliably on equipment, it is possible to significantly more efficient preventing loosens, and it is elastic that U-shaped end possesses certain mechanics, it is possible to prevents from loosening.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
A kind of anti-virtual connection binding post, including terminals, described terminals outer wall is provided with helicitic texture, described terminals one end is fixing connects U-shaped end, described U-shaped end includes two contact surfaces, is provided with U-lag between described contact surface, and described contact surface side is provided with screw, corresponding connection trip bolt, described trip bolt one end attaching nut on described screw.
Furthermore, being provided with wire inserting slot bottom described terminals, the material of described terminals is copper or aluminum.
Furthermore, described screw quantity is two.
Furthermore, described contact surface the first half is semicircle, and the latter half is rectangle.
The method have the benefit that by arranging two contact surfaces and U-lag, increase contact area, increase heat radiation, what decrease that junction point causes owing to expanding with heat and contract with cold loosens, simultaneously because be provided with two screws, this binding post is made to be fixed to reliably on equipment, it is possible to significantly more efficient preventing loosens, and it is elastic that U-shaped end possesses certain mechanics, it is possible to prevents from loosening.
