Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a cable cold-shrink outdoor terminal with a protective structure. Background Technology

[0002] Cold shrink cable outdoor terminals are widely used in power, communication, railway, subway, mining, petroleum and other fields for outdoor cable terminal treatment. They use cold shrink technology to seal, insulate and protect the cable, effectively improving the cable's operational stability in harsh outdoor environments. Cold shrink technology utilizes the memory effect of special elastic materials (such as silicone rubber) to shrink and tightly fit the cable surface by removing the supporting medium (such as plastic strips or springs) inside the pre-expanded sleeve.

[0003] Utility model patent CN222802517U discloses an outdoor terminal for a cold-shrink cable, comprising a three-finger sleeve, an outer cable sheath at the bottom of the three-finger sleeve, an insulating tube at the top of the three-finger sleeve, a terminal body at the end of the insulating tube away from the three-finger sleeve, a sealing tube at the end of the terminal body away from the three-finger sleeve, and a terminal block at the end of the sealing tube away from the terminal body. Several umbrella skirts are arranged at equal intervals on the outer side of the terminal body. In this utility model, the structure of the umbrella skirts is relatively flexible, allowing for size replacement as needed. Furthermore, maintenance is convenient when a single umbrella skirt is damaged, eliminating the need for complete replacement and avoiding the cumbersome process of overall replacement. Additionally, due to the flexible installation structure of the umbrella skirts, their installation position is easily adjustable, thus avoiding limitations in use.

[0004] However, existing cold-shrink cable outdoor terminals are not easy to reinforce in actual use. Cold-shrink terminals are usually made of silicone rubber and are lightweight, but if the cable core is long and the weight of the terminal itself is added, the branched cable may be bent under stress, especially when installed vertically or at an angle, the effect of gravity is more obvious, which will cause cable fatigue in the long run and affect the service life. Utility Model Content

[0005] This utility model provides a cable cold-shrink outdoor terminal with a protective structure, which has the advantage of being easy to support and protect, thus solving the problem that existing branched cables are difficult to reinforce when bent under stress.

[0006] To achieve the purpose of support and protection, this utility model provides the following technical solution: a cable cold-shrink outdoor terminal with a protective structure, including a cable body, a cable core and a terminal block, and further including:

[0007] A cold-shrink three-finger sleeve is installed on the main body of the cable. An installation assembly is sleeved on the outside of the cold-shrink three-finger sleeve. The installation assembly includes an opening limiting tube, a connecting frame, a limiting bolt, and a limiting cap.

[0008] A support frame is installed inside the connecting frame. An adjusting column is rotatably connected to one end of the support frame.

The connecting assembly includes an A mounting ring, a B mounting ring, a connecting support, and a connecting post.

[0010] As a preferred embodiment of the present invention, the installation assembly includes an opening limiting tube fitting sleeved on the outside of the cold shrink three-finger sleeve, and three connecting brackets are fixedly connected to the surface of the opening limiting tube fitting.

[0011] As a preferred embodiment of this utility model, both ends of the opening limiting pipe fitting are provided with mounting holes, and a limiting bolt passes through the interior of the mounting hole. One end of the limiting bolt is threadedly connected to a limiting cap.

[0012] As a preferred embodiment of this utility model, the adjustment support assembly includes an outer support column fixedly connected to the surface of the adjustment column, an inner support column slidably connected inside the outer support column, an adjustment hole being provided at the top of the surface of the outer support column, and an adjustment bolt being threadedly connected inside the adjustment hole.

[0013] As a preferred embodiment of this utility model, the surface of the inner support column is provided with a plurality of fixing holes, which are adapted to the adjusting bolts.

[0014] As a preferred technical solution of this utility model, the connecting component includes an A mounting ring fixedly connected to the surface of the skirt-type cold shrink outdoor terminal body, and B mounting rings are connected to both sides of the A mounting ring by assembly bolt threads.

[0016] As a preferred technical solution of this utility model, the material of the cold shrink three-finger sleeve, the three skirt-type cold shrink outdoor terminal bodies, and the cold shrink straight tube is all silicone rubber.

[0017] Compared with the prior art, this utility model provides a cable cold-shrink outdoor terminal with a protective structure, which has the following beneficial effects:

[0018] This cable shrink outdoor terminal with a protective structure can be adapted to different cable shrink outdoor terminals by setting an adjustable support component. During use, the support height needs to be adjusted according to the installation position of the terminal block. After unscrewing the adjusting bolt and adjusting the position of the inner support column to the outer support column, tighten the adjusting bolt to limit the support height, thereby facilitating the adjustment of the support height and helping to improve the adaptability of the cable shrink outdoor terminal.

[0019] This cable shrinking outdoor terminal with a protective structure can achieve the purpose of supporting the cable shrinking outdoor terminal by setting up installation components and connection components. In use, the opening limiting fitting is clamped on the outside of the assembled cable shrinking outdoor terminal's three-finger sleeve and fixed with the limiting bolt.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 This utility model discloses a cable cold-shrink outdoor terminal with a protective structure, including a cable body 1, a cable core 2, and a terminal block 3, and further including:

[0027] A cold-shrink three-finger sleeve 4 is installed on the cable body 1. An installation component 5 is sleeved on the outside of the cold-shrink three-finger sleeve 4. The installation component 5 includes an opening limiting tube 501, a connecting bracket 502, a limiting bolt 503, and a limiting cap 504.

[0028] A support frame 6 is installed inside the connecting frame 502. An adjusting column 7 is rotatably connected to one end of the support frame 6. An adjusting support assembly 8 is fixedly connected to the surface of the adjusting column 7. The adjusting support assembly 8 includes an outer supporting column 801, an inner supporting column 802, and an adjusting bolt 803.

[0029] Three cold-shrink straight tubes 11 and three skirt-type cold-shrink outdoor terminal bodies 9 are set outside the cable core 2.

The connecting component 10 includes an A mounting ring 1001, a B mounting ring 1002, a connecting support 1003, and a connecting post 1004.

[0030] Specifically, the installation component 5 includes an open limiting tube 501 that is sleeved on the outside of the cold shrink three-finger sleeve 4. Three connecting brackets 502 are fixedly connected to the surface of the open limiting tube 501. Both ends of the open limiting tube 501 are provided with installation holes. A limiting bolt 503 passes through the inside of the installation hole. One end of the limiting bolt 503 is threadedly connected to a limiting cap 504.

[0031] In this embodiment, during use, the opening limiting fitting 501 is clipped onto the outside of the cold shrink three-finger sleeve 4 of the assembled cable cold shrink outdoor terminal and fixed with the limiting bolt 503.

[0032] Specifically, the adjustment support assembly 8 includes an outer support column 801 fixedly connected to the surface of the adjustment column 7, an inner support column 802 slidably connected inside the outer support column 801, an adjustment hole is opened at the top of the surface of the outer support column 801, and an adjustment bolt 803 is threadedly connected inside the adjustment hole; the surface of the inner support column 802 is provided with several fixing holes, which are adapted to the adjustment bolt 803.

[0033] In this implementation scheme, during use, the support height needs to be adjusted according to the installation position of the terminal block 3. After unscrewing the adjusting bolt 803 and adjusting the position of the inner support column 802 relative to the outer support column 801, the adjusting bolt 803 is screwed on to limit the support height.

[0034] Specifically, the connecting assembly 10 includes an A mounting ring 1001 fixedly connected to the surface of the skirt-type cold shrink outdoor terminal body 9, and B mounting rings 1002 connected to both sides of the A mounting ring 1001 by assembly bolt threads; a connecting support 1003 is fixedly connected to one side of the B mounting ring 1002, and a connecting post 1004 is rotatably connected to the inside of one end of the connecting support 1003, and the bottom end of the connecting post 1004 is fixedly connected to the top end of the inner support post 802.

[0035] In this embodiment, the connection position of mounting ring A 1001 and mounting ring B 1002 is adjusted to facilitate support from outer column 801 and inner column 802. Additionally, the connecting column 1004 facilitates adjustment of the support angle.

[0036] Specifically, the materials used for the cold shrink three-finger sleeve 4, the three skirt-type cold shrink outdoor terminal bodies 9, and the cold shrink straight tube 11 are all silicone rubber.

[0037] In this embodiment, the cold-shrink three-finger sleeve 4, the three skirt-type cold-shrink outdoor terminals 9, and the cold-shrink straight tube 11 are all made of silicone rubber, which helps to increase insulation and durability.

[0038] The working principle and usage process of this utility model are as follows: In use, the opening limiting fitting 501 is clipped onto the outside of the assembled cable cold shrink outdoor terminal cold shrink three-finger sleeve 4 and fixed with the limiting bolt 503. According to the installation position of the terminal 3, the support height needs to be adjusted.
