Description

Technical Field

[0001] The utility model belongs to the technical field of electromechanical installation, and particularly relates to a cable adapter. Background Art

[0002] Cable adapters are also called cable joints. After the cables are laid, in order to make them a continuous line, the various segments must be connected as a whole. These connection points are called cable joints. Cable joints are used to lock and fix the incoming and outgoing cables, and play a role in waterproofing, dustproofing and vibration-proofing. When using existing cable adapters, two cables need to be inserted into the through holes on both sides of the cable adapter respectively, and then the two cables are fixed respectively. Since the cables are energized by contacting the conductive rods inside the cable adapter, one end of the cable needs to be in close contact with the conductive rods when docking;

[0003] However, the existing cable adapter cannot immediately fix the inserted cable after the cable is inserted, which may cause the cable to be pulled out partially due to shaking or human error when fixing the cable after insertion, thereby causing it to be unable to make close contact with the conductive rod, resulting in the cable not being energized after being fixed, requiring the staff to re-fix the cable, which is very inconvenient. Therefore, it is necessary to design a new type of cable adapter to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a cable adapter which solves the problem that the prior art cable adapter cannot immediately fix the inserted cable after insertion, and the cable may not be in close contact with the conductive rod due to shaking, resulting in the need for repeated installation.

[0023] Furthermore, in order to achieve the effect of fixing the cable immediately when the cable contacts the conductive rod 23, the upper and lower parts of both sides of the rear part of the inner cavity of the docking groove 2 are rotatably connected with a rotating rod 11 through a bearing member, a gear 12 is fixedly connected to the surface of the rotating rod 11, and the top and bottom of the inserting tube 6 and the inside of the docking groove 2 are fixedly connected with an engaging plate 13 meshing with the gear 12, the top end of the rotating rod 11 penetrates the docking groove 2 and extends to the inside of the linkage groove 3, and the end of the rotating rod 11 extending to the inside of the linkage groove 3 is fixedly connected with a ratchet 14.
