Abstract
The invention relates to a waterproof cable joint with a higher clamping force. The waterproof cable joint comprises a main body, a nut and a packing nut, wherein the main body is of a hollow structural column shape; a fixed nut is arranged in the middle of the main body; the two ends of the main body are provided with an externally threaded part and a threaded clamping end with a clamping jaw; the clamping jaw at the threaded clamping end is parallelogram-shaped; the nut with internal threads is arranged on the externally threaded part; a washer is arranged between the nut and the fixed nut; the packing nut matched with the threaded clamping end is arranged at the threaded clamping end; a sealing ring is arranged in the threaded clamping end; the end of the sealing ring has a radian matched with the packing nut. The waterproof cable joint is convenient to manufacture and use, and has higher sealing property and waterproof performance, dust, water vapor and the like are effectively prevented from entry, the stability performance of electrical appliance elements is improved, the safety coefficient is improved, the service life is prolonged, the waterproof cable joint does not need to be frequently replaced, the fixing performance of the packing nut is high, the waterproof cable joint is unlikely to disengage, and the clamping force is effectively improved.
Description
Technical field
The present invention relates to a kind of Waterproof connector of cable with stronger clamping force.
Background technology
Cable joint is the matching product of cable, mainly be used in distribution box, above power distribution cabinet, joint can by cable locking, and the other end can be accessed by above equipment box, also can access on the electrical equipment that import and export are internal thread according to selecting screw thread, common mechanical control cabinet, distribution board, use fixed by machine isoelectric line cable, can effective clamping cables reach waterproof object.
Existing cable joint is in installation process, when cable is through water proof ring and main body, come off because water proof ring is easy to be ejected be shifted to be out of shape even to eject under the active force of cable, make to produce gap between water proof ring and main body, and then make the poorly sealed of cable fixing head, cause extraneous dust, steam etc. enter in casing, affect electric elements stability in casing, reduce the safety of electric elements in casing, stability, and in use locknut can loosen in automatic rollback, even come off, normal instructions for use can not be met, the water resistance of existing Waterproof connector of cable also cannot meet particular/special requirement simultaneously, and the clamping force of Waterproof connector of cable to cable is poor.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides one to have good sealing and water resistance, improves coefficient of safety and the Waterproof connector of cable with stronger clamping force in useful life.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Waterproof connector of cable with stronger clamping force, there is main body, nut and locknut, described main body is hollow structure column, the mid portion of main body is provided with hold-doun nut, the two ends of main body are provided with external thread part and the screw thread pinching end with clamp jaw, on described screw thread pinching end, the shape of clamp jaw is parallelogram, effective raising clamping force, external thread part is provided with and coordinates with tapped nut, packing ring is provided with between nut and hold-doun nut, screw thread pinching end is provided with the locknut coordinated with it, sealing ring is provided with in described screw thread pinching end, the termination of described sealing ring is provided with the radian coordinated with locknut, improve sealing property and anti-water coefficient, effectively meet special occasions requirement.
Further, described packing ring and sealing ring adopt elastomeric material to make, and improve sealing property and water resistance, effectively prevent dust, steam etc. from entering, and improve stability and the coefficient of safety of electric elements.
Further, described main body, nut and locknut all adopt the heat-resisting and plastic cement of good springiness, improve the useful life of product, need not often keep in repair and change, reduce costs, increase work efficiency.
Further, described locknut is provided with anti-slide mark, in use, effectively prevents the generation of skidding, increase work efficiency.
The invention has the beneficial effects as follows: structure of the present invention is simple, manufacture easy to use, there is good sealing and water resistance, effectively prevent dust, steam etc. from entering, improve the stability of electric elements, improve coefficient of safety and useful life, need not often change, and the fixed performance of locknut is good, does not produce and come off, and effectively improve clamping force.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
