Abstract

The utility model relates to a cable screw connector, mainly composed of a plastic circular-cover head screwed cap, a helical plastic basal body, a plastic hexagonal nut and a rubber bush. One end of the plastic circular-cover head screwed cap is provided with is the circular arc inner wall; square teeth are arranged above the helical plastic basal body, and are matched with the rubber bush. The utility model does not generate extra stress, and the tension of a cable transfusion pipe is eliminated; the utility model has the advantages of favorable performance, good protective property and reliable fixation.

Description

The cable screwed union

The utility model relates to a kind of cable joint.

At present, existing cable joint is applicable to that the cable that mostly is cable input, output greatly of adapted fastens bit architecture in power electronics control device, military project, oil, chemical industry, weaving, lathe, plant equipment manufacturing industry, survey control technology, instrument and meter manufacturing and other industries.This cable joint dismounting trouble, moistureproof, explosion-proof performance is poor.

The purpose of this utility model provide a kind of easy accessibility, intensity good, eliminate that tension force, performance are good, waterproof, protection against the tide, dustproof, explosion-proof cable thread joint.

For achieving the above object, technical scheme provided by the utility model is a kind of cable thread joint, it mainly is made up of plastics dome head screw mother, spiral plastic substrate, plastics hex nut, rubber bush, it is the inwall of circular arc that plastics dome head nut has an end, the side's of having tooth on the spiral plastic substrate is equipped with rubber bush on the square tooth.

Compared with prior art, because the fastening location of the utility model cable, block needn't be pulled down easy accessibility when threading.And the utility model does not produce extra-stress, eliminates the tension force of the defeated pipe of cable, and performance is good, and barrier propterty is good, and is fixing reliable.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the structural representation of the utility model cable screwed union;

Fig. 2 is the end view of cable screwed union shown in Figure 1;

Fig. 3 is the front view of spiral plastic substrate of the present utility model;

Fig. 4 is the end view of spiral plastic substrate shown in Figure 3.

Fig. 1, cable screwed union shown in Figure 2, be made up of plastics dome head nut 1, spiral plastic substrate 3, rubber bush 2, plastics hex nut 4, the circular arc inwall of plastics dome head nut 1 compresses the square tooth of spiral plastic substrate 3 when plastics dome head nut 1 is tightened.The side's of having tooth on Fig. 3, the spiral plastic substrate 3 shown in Figure 4 is equipped with rubber bush 2 on the square tooth, the gap between the square tooth is 0.8mm.

When this cable screwed union uses, cable, electric wire are entered circular arc inwall in the spiral plastic substrate 3, plastics dome head nut 1 is tightened promptly securely with cable, cable clamping, the anti-reversing of elasticity " square tooth " of 18 five equilibriums is arranged at plastics dome head nut 1 head, after being equipped with rubber bush 2 clampings, electric wire does not only damage its top layer, and protective is good, and it is extremely strong to prevent breaking away from power.
