Embodiment Construction

[0011] The summary of the invention has described the specific implementation manner of the present invention in detail, does not repeat here, needs to explain as follows: 1. see figure 1 , figure 2 and image 3 , the external dimensions of the cable pier head 7 completely coincide with the pier head cavity 12, when the connecting nut 1 clamps the left and right connecting sleeves 2, the left and right cable pier heads 7 are in the pier head cavity 12 of the left and right connecting sleeves 2 Form a whole inside, and the cable joint will not be broken at the joint under the action of external pulling force and the resistance of the cable pier head 7, which is the greatest advantage of the present invention. 2. See figure 1 , image 3 and Figure 5 , the tapered waterproof ring 4 has a tapered slope, and the frictional resistance between the tapered waterproof ring 4 and the cable insulation 6 is much larger than that between the connection sleeve 2 and the cable insulati...

Abstract

The invention provides a self-waterproof cable coaxial butt joint device with a pier head. The device is mainly used for large cable butt joint. The butt joint is firm. A cable is prevented from being pulled off from the butt joint. The butt joint is short. The device has a self-waterproof function. The device provided by the invention mainly consists of a connection nut 1, connection sleeves 2, a cable copper core 3, a tapered waterproof ring 4, a circular waterproof ring 5 and cable pier heads 7. According to the main working principle, left and right connection sleeves 2 respectively pass through left and right butt joint cables; the end parts of the cable copper core 3 are extruded into the cable pier heads 7 by a dedicated pier head mold; the circular waterproof ring 5 is arranged; the connection nut 1 is rotated; through the connection nut 1, left and right connection sleeves 2 gradually draw close until semicircular grooves 13 of left and right connection sleeves 2 clamp the circular waterproof ring 5, and at the same time left and right cable pier heads 7 draw close; the tapered waterproof ring 4 presses the cable insulation skin 6; and cable butt joint is completed.

Description

technical field [0001] The invention is mainly used for butt jointing of large cables. Background technique [0002] The currently authorized and applied for large cable docking patents are either not securely connected and easily pulled off from the docking place, or the joint at the butt joint is too long to waste cables. Contents of the invention [0003] The present invention solves the above-mentioned problems, it is butted firmly, the cable will not be pulled off from the butt joint, and the joint at the butt joint is short at the same time, and also has self-waterproof function; Shaped waterproof ring 4, circular waterproof ring 5, and cable pier head 7; connecting nut 1 has a pair of internal thread A15 and internal thread B16 that are anti-threaded; connecting sleeve 2 is divided into two left and right, and two left and right connecting sleeves 2 All have an outer insulating layer 9, an inner metal layer 10, a tapered waterproof ring groove 11, a pier head cavit...
