Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of cable interface, in particular to a low-voltage cable branch box anti-winding cable interface. BACKGROUND
[0002] The low-voltage cable branch box is a key equipment for cable line tapping, switching and circuit conversion in the power distribution network, and is mostly used in outdoor environment. When the cable drawn from the low-voltage cable branch box is switched, an intermediate joint needs to be added in the long-distance cable line to improve safety and reduce the cost of cable laying and procurement.
[0003] The cable interface, also known as cable joint, is used to connect each segment of the cable to form a whole after the cable is laid. In order to meet the requirements of multi-line laying, a cable joint with multiple connection ports is sometimes needed.
[0004] However, the cable interface has the following defects in actual use:
[0005] 1. When the existing cable interface connects the conductive cable, the plug of the conductive cable needs to be connected with the cable joint to meet the requirements of switching, tapping and circuit conversion in long-distance power transmission. In order to meet the requirements of quick insertion and quick removal, the traditional cable plug generally adopts a rotatable threaded joint to connect with the cable joint, to ensure the stability and safety of the conductive connection, and to cooperate with the wire structure inside the cable joint to transmit the current. However, when the current is transmitted to the inside of the cable joint for power transmission, the cable needs to be pulled and adjusted multiple times to meet the subsequent safety detection and other laying requirements. At this time, the cable interface is easy to vibrate and be impacted, the mechanical strength inside is large, the electrical performance stability is poor, the signal transmission loss is easily increased, the electromagnetic interference is easily suffered, the electrical continuity and mechanical stability are poor, and the service life is low.
[0006] 2. When the existing cable interface connects the laid cable, the plug of the laid cable needs to be inserted into the inside of the cable interface to realize the power transmission of multiple cables. However, when the cable is actually laid, the laid cable needs to meet the requirements of multi-circuit switching, and the traditional cable interface is difficult to adjust according to the site conditions, which is inconvenient to use.

Meanwhile, when the current on the cable is transmitted inside the cable interface, the split cables can be designed to split the concentrated transmission current, disperse the surface electric field intensity of the current transmission, reduce the ionization phenomenon under high voltage and the energy loss in the discharge process, and effectively improve the transmission efficiency of the current. Moreover, each split cable can be fixed by extrusion (in the longitudinal direction) through the insulating sleeve arranged outside the split cable and the abutting spring arranged inside the insulating sleeve, so as to reduce the probability of shaking and deviation of the split cable caused by external interference when the current is transmitted in the split cable, and maximize the electrical continuity, mechanical stability and service life;
[0028] 2.

On the other hand, the multiple embedded blocks (lower embedded block, intermediate embedded block and upper embedded block) can apply pressure to the metal spring downward, so that the middle part of the metal spring protrudes inward and extrudes the split cable part inside, thereby applying longitudinal pressure to the middle of the split cable, so as to ensure the safety and stability of the split cable during current transmission.
