Description

TECHNICAL FIELD

[0001] The utility model relates to cable installation engineering technical field especially relates to a single core cable shunt, combined cable shunt and cable shunt device. BACKGROUND

[0002] Cable shunting, that is, using a shunt device to divide the current on the main cable for designated electrical equipment, for example, a building, the main cable is a main cable from the power distribution box in the basement to the roof, and the shunt device is used to divide the current of the main cable for each floor or multiple floor users.

[0003] The current shunt device includes a cable piercing clamp, a pre-branch cable, a cable T joint terminal or a cable T joint box. However, the above shunt devices have some defects, for example, the cable piercing clamp is a point contact, and has many fault points, which are often difficult for construction personnel to detect. When the overload current increases, the contact point is easy to heat, and in severe cases, it can cause a fire. The cable stripped of the outer sheath is not effectively protected, which does not meet the electrical installation specifications. The pre-branch cable needs to be measured on site to determine the location of the shunt point, and it is produced by the cable factory. After the product is produced, it is not easy to change, and if the size or position is wrong, it can only be scrapped and reworked. Since the pre-branch head is fixed on the cable, the cable laying needs to use equipment to pull, which can easily damage the branch head, and there are possible fault points, high product and construction costs, and low efficiency. The cable T joint terminal has exposed contact points, and does not have waterproof, dustproof and touchproof functions, which has poor safety and low construction efficiency. The cable stripped of the outer sheath is not effectively protected, which does not meet the electrical installation specifications. The cable T joint box needs to cut the main cable during installation, and needs additional accessories and tools, which causes serious cable waste, occupies a large space, and has high comprehensive cost. In addition, cutting the main cable also increases the fault points.

[0004] To this end, the patent for utility model with publication No. "CN205264874U" discloses a kind of cable integrated branch connector, it includes insulating shell, insulating shuttle stick, metal V-shaped body, metal nut plate, metal bolt and branch line metal bolt, wherein insulating shuttle stick has multiple V-shaped grooves, each V-shaped groove is insulated and isolated, metal V-shaped body is respectively configured in V-shaped groove.Main cable and branch cable can realize the shunt of cable by the cable integrated branch connector.The technical scheme has the advantages of good electrical connection reliability, small installation space occupation and the ability to integrate branch connection on construction site.But the technical scheme still has some deficiencies.For example, the fixed number of V-shaped grooves of insulating shuttle stick, and each actual cable shunt working condition is different, and the number of wire core required by shunt is different, to avoid the mismatch between the number of wire core and the number of metal V-shaped body in insulating shuttle stick in cable integrated branch connector, causing waste, or needing to carry multiple specifications of cable integrated branch connector at the same time, so it will increase the burden of construction personnel.In addition, when installing integrated branch connector, the outer sheath of a considerable length of main cable needs to be stripped, and a space suitable for placing integrated branch connector main body needs to be pricked out between multiple wire cores using metal crowbar to install, which not only increases the construction difficulty, increases the construction cost and affects the construction efficiency, but also causes the cable to be abnormally displaced and bent due to pricking the cable, causing damage to the cable.

Of course, in other embodiments, the main cable conductor 311 can also be directly assembled in the main wire accommodating groove d without stripping the insulating rubber, at this time, the main wire threaded fastener 24 needs to be a sharp threaded fastener to pierce the insulating rubber and the main cable conductor 311 to form an electrically conductive path, and the specific number is not limited.

[0054] In order to make the electrically conductive path formed by the electrically conductive base 2 and the main cable conductor 311 and the branch cable conductor 411 more stable, optionally, please refer to Figure 2 and Figure 3In the embodiment, the conductive base 2 further comprises a main wire pressing sheet 26 arranged in the main wire accommodating groove d and used for electrically contacting the main cable core conductor 311 on one side and the main wire threaded fastener 24 on the other side; and a branch wire pressing sheet 27 arranged in the branch wire accommodating groove f and used for electrically contacting the branch cable core conductor 411 on one side and the branch wire threaded fastener 25 on the other side.

Specifically, the first side wing 11 and the second side wing 12 of the insulating base 1 are integrally injection molded by an insulating material, and the cross section thereof is substantially V-shaped. The V-shaped insulating base 1 structure is conducive to forming a combined cable distributor 200 by abutting the outer side surfaces of the first side wing 11 and / or the second side wing 12 of the insulating base 1 of a plurality of single-core cable distributors 100 against each other. In order to facilitate the fixation of the conductive base 2, optionally, please refer to Figure 2 and Figure 3 In the embodiment, the free end of the first side wing 11 and the second side wing 12 is at least partially bent inward to form a hook-shaped fixing portion 122, and the conductive base 2 is clamped in the assembly groove c through the hook-shaped fixing portion 122.
