Embodiment Construction

[0011] The content of the invention has described the specific implementation of the present invention in detail, and it will not be repeated here. It needs to be explained as follows: 1. Referring to Fig. After the connecting nut 1 clamps the left and right connecting sleeves 2, the left and right cable pier heads 7 form a whole in the pier head cavities 12 of the left and right connecting sleeves 2. Under the resistance of the head 7, the cable will not be broken at the joint, which is the greatest advantage of the present invention. 2. See Figure 1, Figure 3 and Figure 5, the tapered waterproof ring 4 has a conical slope, and the frictional resistance between the tapered waterproof ring 4 and the cable insulation 6 is much larger than that between the connecting sleeve 2 and the cable insulation 6 Therefore, when the left and right connecting sleeves 2 gradually move closer, the tapered waterproof ring grooves 11 of the left and right connecting sleeves 2 will press the tap...

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. Its butt joint is firm, the cable will not be broken from the joint, and the joint at the joint is short, and it also has a self-waterproof function; the present invention mainly consists of a connecting nut (1), a connecting sleeve (2), a cable Core (3), tapered waterproof ring (4), circular waterproof ring (5), cable pier head (7); the connecting nut (1) has a pair of inner thread A (15) and inner Thread B (16); the connecting sleeve (2) is divided into left and right two, and the left and right connecting sleeves (2) have an outer insulating layer (9), an i...
