Embodiment Construction

[0012] Such as figure 1 As shown, an embodiment of a cable joint structure, the joint structure in this embodiment includes two cables respectively having wiring sections, these two cables are a main circuit cable 1 and a branch circuit cable 2, wherein, The connection section 11 of the main circuit cable 1 is arranged in the middle of the main circuit cable 1, the connection section 21 of the branch circuit cable 2 is arranged at one end of the branch circuit cable 2, and the connection sections of the main circuit cable 1 and the branch circuit cable 2 have respectively The sequence corresponds to the exposed conductors of the conductive connection. The exposed conductors of each phase on the main circuit cable 1 and the exposed conductors of each phase on the branch circuit cable 2 are assembled together by crimping fittings 4. The exposed conductors of the main circuit cable 1 A solid insulating sheath 3 that completely wraps the above-mentioned conductive connection is po...

Abstract

The invention provides a cable joint structure, which comprises at least two cables with connection segments, wherein the connection segments of all cables comprise exposed conductors which are in conductive connection correspondingly according to a phase sequence respectively; solid insulating sheaths for completely wrapping the conductive connection parts are cast and solidified on the conductive connection parts of the exposed conductors of the connection segments of all cables, so that, on one hand, effective conductive connection is ensured; and on the other hand, effective insulating protection is also ensured. The cable joint structure can be fabricated on site, can ensure effective connection of a main loop cable and branch loop circuits, is flexible and convenient, can adjust the positions of the conductive connection parts and the sizes of the solid insulating sheaths according to the actual requirements and effectively solves the problems that a branch box is large in floor area, a joint is easy to loosen and the operating maintenance amount is large when branch connection is achieved by the branch box in the past.

Description

technical field [0001] The invention relates to a cable joint structure. Background technique [0002] In the connection mode of low-voltage distribution lines, branch wiring is a more commonly used wiring method. In the branch wiring of low-voltage cable lines, the outer sheath and insulation layer of the main circuit low-voltage cable and the branch circuit low-voltage cable need to be stripped due to the branch connection. , causing damage to the insulation layer of the conductor. In order to ensure the safety of the power supply, it is necessary to restore the insulation performance of the conductor part after the wiring is completed. [0003] In the past, low-voltage cable branch joints used factory-fabricated branch cables or realized branch wiring and insulation recovery of low-voltage cables through external low-voltage cable branch boxes. Among them, the factory prefabricated branch cables not only need strict on-site measurement and long-term processing cycle, but...
