[0030] Specifically, when connecting, first connect the ends of the two cables, then clamp the cable connection in the middle of the accommodating cavity 3 opened by the first half sleeve 1, and the cables at both ends of the connection are clamped and embedded in the entrance of the accommodating cavity 3, then remove the screw from the outermost screw groove, then hold the movable plate 7 and pull it, so that the clamping plate 8 moves close to the connection until it is close to it. At the same time, using the elastic force of the spring, the movable rod moves out of the movable groove opened by the fixed rod, and then the screw is screwed into the corresponding screw groove to complete the clamping and fixing of the connection of the cable end, and finally cover the second half sleeve 2, insert the plug 13 into the slot 14, and finally tighten the fastening bolt to complete the connection between the first half sleeve 1 and the second half sleeve 2, and the connection operation of the cable end can be realized.

[0031] The utility model provides the following Figure 4 ​​​An auxiliary connector for the end of a cable as shown has a fastening structure 9 inside the accommodation cavity 3. The fastening structure 9 includes an upper clamping plate 91, a lower clamping plate 92, two connecting plates 93, a threaded rod 94, a connecting seat 95, an end block 96 and a rod groove 97. The upper clamping plate 91 and the lower clamping plate 92 are arranged inside the accommodation cavity 3 and at both ends of the fixing assembly. The two connecting plates 93 are respectively connected to the outer walls of the upper clamping plate 91 and the lower clamping plate 92. The threaded rod 94 is connected to the connecting plate 93 through a bearing. The connecting seat 95 is connected to the first half sleeve 1. The end block 96 is connected to the end of the threaded rod 94 away from the connecting plate 93. The rod groove 97 is opened inside the connecting seat 95, and the rod groove 97 is threadedly connected to the threaded rod 94.

[0032] A docking rod 911 is connected to the end corner of the upper clamping plate 91 close to the lower clamping plate 92, and a docking groove 912 adapted to the docking rod 911 is opened on the end face of the lower clamping plate 92 close to the upper clamping plate 91.

[0033] Further, referring to Figure 2 As shown, a plate groove 913 is opened on the inner wall of the accommodation cavity 3, and a thread groove 914 adapted to the threaded rod 94 is opened at one end of the inner wall of the connecting sleeve and located in the plate groove 913.

[0034] Through the above technical solution:

[0035] After the cable end joint is clamped and fixed, first take a tool and insert one end of it into the flat slot of the end block 96, and then rotate the tool to drive the threaded rod 94 to rotate in the thread groove 914 and the rod groove 97, so that it drives the upper clamping plate 91 to approach the cable until it is close to the cable surface. The lower clamping plate 92 is attached to the cable according to the above operation. After the upper and lower clamping plates are clamped to the outside of the cable, the docking rod 911 just snaps into the docking groove 912. This operation can fasten the cable segment at the inlet end, further enhancing the firmness after the connection of the two cable ends, avoiding the loosening of the connection caused by the cable being accidentally pulled due to insecure fixation, preventing the joint from falling off and causing leakage and wire breakage, etc., without affecting the use of the cable, and also ensuring the connection effect of the connector. In addition, rotating the threaded rod 94 in the reverse direction according to the above operation can move the upper and lower clamping plates away from the cable, and the fastening operation of the cable can be released.

[0036] The present utility model provides an auxiliary connector for the end of a cable as shown in Figure 5 As shown, a filling structure 12 is provided on the connecting seat 95. The filling structure 12 includes a vertical groove 121, a plurality of inclined grooves 122, an oil inlet groove 123, a plug block 124 and an outer block 125.

[0037] The vertical groove 121, several inclined grooves 122 and the oil inlet groove 123 are formed on the inner wall of the connecting seat 95. The several inclined grooves 122 are arranged equidistantly and uniformly on one side of the several inclined grooves 122, and the oil inlet groove 123 is arranged at the upper end of the vertical groove 121.

[0038] The plug block 124 is clamped at the inlet end of the oil inlet groove 123, and the outer block 125 is connected to one end of the plug block 124, and the outer block 125 is arranged on the outer surface wall of the connecting seat 95.

[0039] Through the above technical solution:

[0040] When the threaded rod 94 is difficult to screw due to oxidation reaction caused by moisture, first hold the outer block 125 and pull it to pull out the plug block 124 from the inlet port of the oil inlet groove 123. Then inject lubricating oil into the vertical groove 121 through the oil inlet groove 123. Immediately afterwards, the lubricating oil flows into the rod groove 97 through the inclined groove 122. At this time, the lubricating oil contacts the surface of the threaded rod 94. This operation can lubricate the threaded rod 94, effectively reduce the friction between the threaded rod 94 and the rod groove 97, and facilitate the quick lubrication of the threaded rod 94. In addition, it also avoids the drawback that the rusty threaded rod 94 is stuck and cannot normally fasten or release the fastening of the cable, ensuring the normal use of the fastening structure 9.

[0041] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention.
