Problems solved by technology
[0004] Problems and shortcomings of the existing technology: the existing injection molding process requires cable companies to purchase large-scale injection hydraulic equipment, and a large production site is required for cooling of the connected body after injection.
The problem caused by this is that the construction party and the cable manufacturer shirk each other, and it is impossible to determine the responsible party for the cable problem.
And if one of the connectors of the whole cable is not powered, it will cause the whole cable or even the whole batch of cables to fail the electrical acceptance.
The re-injection of branch cables requires large-scale injection hydraulic equipment, which cannot be reproduced on site

Embodiment Construction
[0012] Such as figure 1 As shown, a single-cavity cable box for a single-core branch cable according to the present invention, the cable box is composed of two symmetrical shells 1, and a hollow space for placing a single-core branch cable is arranged in the middle of the cable box. Cavity 2.
[0013] The two symmetrical shells 1 are fastened together by multiple sets of bolts 3 to form a sealed single-chamber cable box.
[0014] The working principle of the present invention is: make a branch cable box in advance. The cable box is divided into upper and lower two symmetrical parts, and there is a cavity in the middle. Put the crimped branch connector directly into the cable box, then fix the upper and lower branch cable boxes, and keep them sealed.
[0015] This kind of branch cable box can be prefabricated. When the branch cables are mass-produced, it is not necessary for each cable company to purchase large-scale injection hydraulic equipment. It is only necessary to orde...

The invention discloses a single-cavity cable box for single-core branch cables. The cable box is composed of two symmetrical shells, and a cavity used for containing the single-core branch cables is formed in the middle of the cable box. The cable box can be prefabricated, when the branch cables are produced in a batched mode, it is not necessary that all cable enterprises purchase large injection hydraulic devices, the cable enterprises just need to independently order the branch cable boxes with the proper sizes, and a large amount of equipment cost is reduced for cable manufacturers; compared with the prior art that all branch cable connecting bodies need to be cooled after being injection molding and a large production site is occupied, the single-cavity cable box has the advantages that the production efficiency is greatly improved, and a large area of production site is saved; the cable box for the branch cables can be dismantled at the construction site, reasons can be analyzed, re-manufacturing can be conducted on the site, the situation of changing or refunding of a whole cable is avoided when a certain connecting body goes wrong, the site construction progress is accelerated, and the risk of cable changing or refunding is lowered for the cable manufacturers.
Description
[0001] technical field [0002] The invention belongs to the field of power cables, in particular to a single-cavity cable box for single-core branch cables. Background technique [0003] According to the standard JB / T10636-2006 of the Ministry of Machinery Industry for the existing branch cables, the branch connectors of the branch cables should be manufactured by the corresponding polyvinyl chloride or polyolefin injection molding process according to the cable model. Its main structure and principle are to crimp the main cable and the branch cable with a "C"-shaped tube, then put the crimped cable in a fixed mold, and then inject the corresponding PVC or polyolefin insulation into the mold. The material is then cooled and shaped. [0004] Problems and shortcomings of the existing technology: the existing injection molding process requires cable companies to purchase large-scale injection hydraulic equipment, and a large production site is required for cooling the connect...
