Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a distribution box with a cable anti-drop structure. Background Art

[0002] A distribution box is a device widely used in the construction industry or the power industry. It is used as a wiring device for power input and output terminals of various electrical equipment. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. The distribution box contains various electrical equipment. The distribution box is divided into indoor and outdoor types. The wires in the distribution box are usually connected to the electrical equipment in the distribution box through wire conduits buried underground. When maintaining the electrical equipment in the distribution box, it is usually necessary to thread or pull the cables in the wire conduits.

[0003] However, when maintaining the above-mentioned distribution box, since the cables are freely placed in the wire duct, when the distribution box needs to be wired, accidentally pulling the cables will cause the cables to fall off the already configured electrical components, which will cause power outages or safety hazards to the electrical equipment. In view of this, we propose a distribution box with a cable anti-fall-off structure. Utility Model Content

[0004] The utility model aims to provide a distribution box with a cable anti-drop structure to solve the problems raised in the above background technology.

[0008] A clamping ring, a through groove is provided on the top end surface of the fixing block, the through groove penetrates the fixing block, the through groove is connected to the tube body, a clamping ring is fixedly connected to the inner wall of the through groove, and a clamping groove is provided on the side wall of the clamping ring;

[0009] A stopper is arranged in the through groove, a side wall of the stopper is fixedly connected to a limiting rod, and a rubber ring is fixedly connected to the side wall of the stopper.

[0010] Preferably, the rubber ring protrudes from the side wall of the limiting rod, and a chamfer is provided at the edge of the rubber ring, and the chamfer is in a barb shape.

[0011] Preferably, a limiting groove is provided on the top of the fixing block, and the limiting groove is engaged with the limiting rod.

[0012] Preferably, the bolt is threadedly connected to the fixed block, and the fixed block and the movable block are fixed together by the bolt, thereby achieving clamping of the cable.

[0013] Preferably, the clamping ring is arranged on the inner wall of the through groove in an upwardly inclined shape. The clamping ring arranged in an upwardly inclined shape allows the cable to be smoothly inserted into the cabinet from bottom to top, but when the cable is pulled from below, the clamping ring clamps the cable to prevent the cable from moving downward, thereby preventing the cable from falling off the electrical component.

[0014] Preferably, a groove is provided on the front of the movable block, and the spring abuts against the inner wall of the groove. The spring creates a suitable pressure between the movable block and the fixed block, thereby preventing the fixed block and the movable block from being over-clamped and causing damage to the cable.

[0015] Compared with the prior art, the utility model provides a distribution box with a cable anti-drop structure, which has the following beneficial effects:

[0016] 1. The distribution box with a cable anti-drop structure is provided with a fixed block, a movable block, a clamping ring, and a stopper. The clamping ring is arranged on the inner wall of the through groove in an upwardly inclined shape, so that the cable can be smoothly inserted into the cabinet from bottom to top, but when the cable is pulled from below, the clamping ring clamps the cable to prevent the cable from moving downward, thereby preventing the cable from falling off the electrical component. The opening of the side wall of the stopper and the clamping groove arranged on the clamping ring are used to clamp a single cable, so as to avoid the situation where the cable is not clamped tightly due to the entanglement between the cables when several groups of cables are inserted, so that the cable can be better contacted with the clamping ring, thereby improving the cable anti-drop effect.

[0017] 2. The distribution box with a cable anti-drop structure increases the friction between the cable and the block by setting a rubber ring, thereby preventing the cable from being pulled out of the electrical component. The barbed rubber ring can provide better resistance when pulling the cable to prevent the cable from being pulled out. At the same time, the rubber ring contacts the cable sheath to prevent the cable sheath from being damaged when the cable is pulled. BRIEF DESCRIPTION OF THE DRAWINGS
