Detailed Description
A, basic structure
As shown in fig. 1, the cable relay connector of the present invention mainly comprises a connecting body 7, an inner taper sleeve 6, a compression nut 5, an anti-rotation nut 3 and a thrust ring 2; the connecting main body is of a bilateral symmetry structure, the middle part of the connecting main body is of a hexagonal or square structure convenient to fix, and the left side and the right side of the connecting main body are provided with a conical inner hole 8 and an external thread I10; the inner taper sleeve is made of a material with good drawability and is provided with a taper head matched with a taper inner hole (with the same angle), the inner surface of the inner taper sleeve is rough (a barb-shaped bulge can be arranged), the tail part of the taper head is provided with an outer bulge clamping seat 9, the inner side of the outer bulge clamping seat is provided with a pressure-bearing ring 4, the tail end of the inner taper sleeve is provided with a second-order external thread, the second-order external thread consists of an inner tight thread 12 and an outer anti-withdrawal thread 13, the diameter of the tight thread is larger than that of the anti-withdrawal thread, the tight thread and the anti-withdrawal thread are respectively matched with the inner threads of the anti-rotation nut and the anti-withdrawal ring, and the inner taper sleeve and a cable; the compression nut is a hollow pipe fitting, one end of the hollow pipe fitting is provided with a first internal thread matched with the first external thread, and the other end of the hollow pipe fitting is provided with an internal convex clamping seat 11 matched with the convex clamping seat; the anti-rotation nut and the thrust ring are both hollow pipe fittings, and the hollow pipe fittings are respectively provided with internal threads matched with the second-order external threads.
Wherein the external thread or the internal thread is a conventional thread or a trapezoidal thread. The inner taper sleeve may be designed with openings to enhance flexibility, which when compressed will embed into the interstices of the strands of the cable, increasing contact area and connection strength. Considering that the inner taper sleeve has a thinner wall and is opened for increasing elasticity, in order to prevent the problem of possible fracture during the extrusion process, the pressure per unit area is reduced by increasing the contact area, thereby increasing the design of the bearing ring. The anti-rotation nut is further compressed and compacted to form a seal to prevent liquid ingress and to prevent rotation of the inner taper sleeve and cable during installation and removal. The thrust ring is used for further preventing the threads from loosening and axial rotation after connection, and is matched with the anti-rotation nut to be used for bringing the inner taper sleeve out during disassembly.
Second, use method
1. The thrust ring, the anti-rotation nut, the pressing nut and the inner taper sleeve are sequentially sleeved into the cable 1.
2. The cable is inserted into the tapered bore of the connecting body.
3. The bearing ring is pressed into the groove at the inner side of the outer raised clamping seat of the inner taper sleeve.
4. The locking sleeve is firstly screwed, and then the nut and the anti-withdrawal nut are sequentially screwed tightly.
