Description

Technical Field

[0001] The utility model relates to the technical field of connection, in particular to a low-smoke halogen-free cable that is easy to connect. Background Art

[0002] Most cable sheaths are made of polyethylene, polyvinyl chloride or thermoplastic polyurethane. If caught in fire, chlorine-containing plastics will release toxic hydrogen chloride, and if they come into contact with water, they will produce hydrochloric acid. Low-smoke halogen-free materials will not release hydrogen halides or other acids when caught in fire.

[0003] In the existing low-smoke halogen-free cable connectors, most of them are elastic rotating clamping components. When connecting and disassembling, it is only necessary to rotate the rotating body to shrink the arc-shaped telescopic plate so that the upper and lower slots are aligned, and the connecting end can be pulled out, which can achieve convenient and efficient connection and disassembly.

[0004] However, in actual use, although the above-mentioned equipment can be easily disassembled and connected, in the case of accidental rotation due to certain external forces, the connection may be disconnected, resulting in safety hazards. In view of this, we propose a low-smoke halogen-free cable that is easy to connect. Utility Model Content

[0005] The utility model aims to provide a low-smoke halogen-free cable which is easy to connect, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a low-smoke halogen-free cable that is easy to connect, comprising a halogen-free wire, the outer surface of the halogen-free wire is provided with a front fixing body, the outer surface of the front fixing body is provided with an anti-slip assembly, the outer surface of the anti-slip assembly is provided with a rotating body, the outer surface of the rotating body is provided with a rear fixing body, the outer surface of the rear fixing body is provided with an arc-shaped telescopic plate, the anti-slip assembly comprises a connecting rod, the outer surface of the front fixing body is fixedly connected to the connecting rod, the outer surface of the connecting rod is fixedly connected to a movable wall, the outer surface of the movable wall is provided with a groove, and the outer surface of the movable wall The outer surface of the rear fixed body is fixedly connected with a right-hand gear plate, the outer surface of the rear fixed body is fixedly connected with a supporting body, the outer surface of the supporting body is rotatably mounted with a rotating gear, the outer surface of the rear fixed body is fixedly connected with a fixed wall, the outer surface of the fixed wall is provided with a No. 1 telescopic plate, one end of the No. 1 telescopic plate is fixedly connected with a limiting block, the outer surface of the rear fixed body is provided with a No. 2 telescopic plate, one end of the No. 2 telescopic plate is fixedly connected with a left-hand gear plate, one end of the left-hand gear plate is fixedly connected with a touch inclined plate, one end of the touch inclined plate is movably connected with a limiting block, and the rotating gear meshes with the left-hand gear plate and the right-hand gear plate.

[0007] Preferably, the inclined surface of the limiting block is matched with the lower inclined surface of the groove, so that when the limiting block is forced to move forward, it can limit the displacement of the groove.

[0008] Preferably, the length of the left gear plate is equal to the length of the right gear plate, so that the left gear plate and the right gear plate can operate stably.

[0009] Preferably, the number of the anti-slip components is several, and the several anti-slip components are arranged in a circular array on the outer surface of the rear fixing body, so that the anti-slip performance is greatly improved.

[0010] Preferably, the outer surface of the fixed wall is provided with a fixed limiting component, and the fixed limiting component includes an elastic telescopic pile. The outer surface of the fixed wall is provided with an elastic telescopic pile, one end of the elastic telescopic pile is fixedly connected to a triangular clamping block, and the outer surface of the movable wall is provided with a triangular transverse groove.

[0011] Preferably, the triangular clamping block is matched with the triangular transverse groove, so that when the triangular clamping block touches the movable wall, it can be smoothly clamped into the movable wall.

[0012] Compared with the prior art, the utility model provides a low-smoke halogen-free cable that is easy to connect and has the following beneficial effects:

[0013] 1. For the low-smoke halogen-free cable that is easy to connect, when the cable connection is disassembled daily, the rotating body is twisted to align the slots, and then the connecting rod can be slowly pulled out. The continuous pulling force causes the connecting rod and the movable wall to be lifted, so that the right gear plate is lifted and drives the rotating gear to rotate, so that the left gear plate moves downward. At this time, the No. 2 telescopic plate is contracted, and the inclined plate is touched and no longer pushes the limiting block to block the lower inclined surface of the groove. At this time, the connecting rod and the movable wall can be pulled out, so that the front fixed body is separated from the rear fixed body. When the rotating body is accidentally touched and rotated, because there is no continuous upward pulling force, the movable wall and the right gear plate will be restricted by the limiting block and the rotating gear, so that the connection will not be disassembled.

[0014] 2. When the low-smoke halogen-free cable is not disassembled on a daily basis, the triangular clamping block on the elastic telescopic pile will continuously squeeze the triangular transverse groove, so that the connecting rod and the movable wall will fit the rear fixed body more closely, so that when the rotating body is accidentally touched and rotated, the connecting rod and the movable wall will not be pulled away from the rear fixed body due to gravity or some smaller pulling force, so that the overall connection stability is greatly increased.
