Description
Technical field
The utility model belongs to power electronics wiring technique field, particularly relates to a kind of crimpless formula binding post of core exit of fastening electric wire.
Background technology
As everyone knows, the conveying of electric energy completes conveying by electric wire, and binding post is exactly for realizing a kind of accessory product be electrically connected, the industrial category being divided into connector.Along with industrial automatization is more and more higher and Industry Control requires more and more stricter, accurate, the consumption of binding post goes up gradually.Along with the development of electron trade, the scope of application of binding post gets more and more, and kind also gets more and more.At present for the large-scale circular cable of multiply spiral core, during general connection, core is inserted in the cable plug-in opening of binding post, then carry out pressurized distortion by clamping tool, itself and binding post are fastenedly connected; This kind of local crimping mode easily makes the core cross section of electric wire cause deformation damage due to crimping in crimping process, thus cause the reduced cross-sectional area of core, to cause local pyrexia like this by crimping place of electric wire at electric current, the even phenomenon of scaling loss; After above-mentioned local compression joint type binding post crimping, the core of its electric wire is out of shape, also result in the tensile strength of variant part simultaneously, warping resistance intensity declines greatly, and then easily occur that crimping place is ruptured, electric wire departs from the phenomenon of binding post, the generation of this kind of phenomenon, will bring on the one hand cannot the problem of normal transmission of electric energy, the potential safety hazard that existence is larger on the other hand; Above-mentioned local compression joint type binding post, when physical cabling, often needs special crimping apparatus or instrument just can complete, otherwise can not meet wiring specification, be therefore subject to certain limitation; In addition compression joint type binding post almost cannot utilize by secondary, causes the waste of resource, the increase of maintenance cost.
Summary of the invention
The utility model for solve in known technology the technical problem that exists and provide a kind of structure simple, compression joint area easy to connect, not destroy cable is installed, ensure the reliable contacts of cable, meet the requirement by enough electric currents, reduce the potential safety hazard caused because wiring is insecure, reduce the crimpless formula binding post of the phenomenon causing power failure because wiring is insecure.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
A kind of crimpless formula binding post, comprise binding post body, it is characterized in that: described binding post body comprises outer connecting portion and cable cartridge part, above-mentioned outer connecting portion is provided with installing hole; Above-mentioned cable cartridge part is provided with cable plug-in opening, and cable plug-in opening is divided into two sections, is respectively wedge-shaped segment and thread segment; In the wedge-shaped segment of above-mentioned cable plug-in opening, be fitted with wedge shape dead ring, described wedge shape dead ring is in axial direction provided with open flexible notch; Be equipped with clamp nut at the thread segment of above-mentioned cable plug-in opening, described clamp nut is provided with the centre bore for installing cable.
The utility model can also adopt following technical measures:
Described open flexible notch be straight trough.
Described open flexible notch is skewed slot, and the angle of inclination of skewed slot is consistent with the wedge angle of cable plug-in opening.
The length of described wedge shape dead ring is 2/3 of cable cartridge part length.
The width of described open flexible notch is 0.5 ~ 3mm.
The advantage that the utility model has and good effect are: because the utility model adopts technique scheme, the problem that the core sectional area that Wire cable core can be avoided when wiring to cause because of local compression external force pressurized reduces or damages, specific purpose tool is clamped without the need to other when physical cabling, and not by place, the restriction of operating environment, only spanner need be adopted, the traditional instrument such as pliers can complete wiring, thus reduce operation, also avoid the problem that the line office caused because of compression joint type wiring shortens simultaneously, in addition, binding post can repeatedly reuse, decrease the wasting of resources, save maintenance cost, the utility model is applied in power transmission and distribution supply line, power supply possibility and fail safe can be greatly improved, decrease the frequency of power cut and interruption duration that cause because wiring comes off, for society and enterprise create larger economic benefit and social benefit.
