Description

Technical Field

[0001] This utility model relates to the field of AC cable heat shrink terminal installation technology, and in particular to an AC cable heat shrink terminal. Background Technology

[0002] Heat-shrinkable cable terminations are insulating sleeves used to protect cable ends. They are made by injection molding of elastomeric materials (commonly silicone rubber and ethylene propylene rubber) in a factory, followed by diameter expansion and lining with plastic spiral supports to form various cable accessories. Heat-shrinkable cable terminations integrate waterproofing, stress control, shielding, and insulation, possessing excellent electrical and mechanical properties. They can be used for extended periods in various harsh environments and have advantages such as light weight and easy installation. Heat-shrinkable cable terminations are widely used in power, petrochemical, metallurgical, and railway industries.

[0003] Existing patent CN223218813U discloses a heat-shrinkable cable termination. This invention includes a heat-shrinkable termination body, with an array of insulating tubes mounted on the upper side of the body. Terminals are connected in an array to the upper side of the body, and an array of support plates are fixedly connected to the upper side of the body. This invention uses a telescopic pressure plate and rubber blocks to position the insulating tubes, making them more stable and reliable. A support recess and a U-shaped clamping plate are then used to support the heat-shrinkable termination, ensuring its stability and preventing it from easily detaching and exposing the cable, thus improving the safety of the cable termination during use. A protective sleeve on a circular ring further enhances the protective capability of the heat-shrinkable cable termination.

[0004] However, while existing patent CN223218813U uses telescopic pressure plates and rubber blocks to position the insulating tube, making the insulating tube on the cable heat shrinkable terminal head more stable and reliable, and subsequently uses support concave plates and U-shaped clamping plates to support the heat shrinkable terminal head, ensuring its stability and preventing it from easily detaching and exposing the cable, thus improving the safety of using the cable heat shrinkable terminal head, and further increasing the protective capability of the cable heat shrinkable terminal head by using a shielding sleeve on the ring to protect the heat shrinkable terminal head, when the heat shrinkable terminal head is pulled by the outside, it may affect the internal stability of the terminal head, and may even pose a risk of detachment.

[0005] Therefore, we propose a heat-shrinkable termination for AC cables. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a heat-shrinkable AC cable termination.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An AC cable heat shrink terminal includes a first connecting end, a mounting component is provided on the top of the first connecting end, a first stop is fixedly provided on the top of the first connecting end, and a second stop is fixedly provided on the top of the first connecting end on the side away from the first stop.

[0008] As a further improvement of this utility model: a limiting block is movably provided in the middle of the first block and the second block, and one side of the limiting block is hinged to the first block.

[0009] As a further improvement of this utility model: the other side of the limiting block is hinged to the second stop block, and a barb is fixedly provided on one side of the limiting block.

[0010] As a further embodiment of this utility model: a cable body is fixedly provided on the inner side of the first connecting end, and a telescopic shaft is provided at the middle of the limiting pressure block and the first connecting end.

[0011] As a further improvement of this utility model: a spring is provided on the outer side of the telescopic shaft, and a second connecting end is provided on one side of the first connecting end.

[0012] As a further embodiment of this utility model: the second connecting end is disposed on the outside of the cable body, and a limit slot is fixedly provided on the top of the second connecting end.

[0013] Compared with the prior art, this utility model provides a heat-shrinkable AC cable termination head, which has the following advantages: This utility model, through the installation of the mounting components, uses the inner sides of the first and second connecting ends for mounting the cable body. When the length of the first connecting end is insufficient, the second connecting end can be added to wrap the cable body, thereby achieving protection for the cable body.

[0014] In this invention, when the second connecting end is installed, the user can press the limiting block to retract the telescopic shaft and spring, causing the other side of the limiting block to lift up, which in turn causes the barb to lift up. At this time, the second connecting end is installed so that it completely wraps around the cable body. When the user releases their finger, the telescopic shaft and spring return to their original positions, causing the barb to return to its original position and snap into the inner side of the limiting slot. When the second connecting end is pulled, it can prevent it from falling off.

[0015] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description
