Description

Technical Field

[0001] The utility model relates to the technical field of cold shrink cable outdoor terminals, in particular to a cold shrink cable outdoor terminal. Background Art

[0002] The cold shrink cable outdoor terminal is a device widely used for outdoor cable terminal processing in the fields of electricity, communication, railway, subway, mining, petroleum, etc. It uses cold shrink technology to achieve sealing, insulation and protection of cables, effectively improving the operating stability of cables in harsh outdoor environments. The cold shrink technology utilizes the memory effect of special elastic materials (such as silicone rubber) to shrink the casing and fit tightly to the cable surface by removing the supporting medium (such as plastic strips or springs) in the pre-expanded casing, thereby achieving waterproof, moisture-proof, dust-proof, and UV-proof effects. The main function of the cold shrink cable outdoor terminal is to perform terminal processing on the cable, including connection, insulation, protection and other functions, to ensure the stable operation of the cable in harsh outdoor environments. It is usually composed of cold shrink casing, insulating filler, waterproof seal, cable fixing clamp, grounding wire and other parts. The cold shrink cable outdoor terminal has the advantages of easy installation, good sealing performance, excellent insulation performance, good weather resistance, and reliable electrical performance.

[0003] The outdoor terminal is an important component of the outdoor cold shrink cable. However, the traditional outdoor terminal still has some shortcomings. For example, the structure of the shed part is relatively fixed, which makes it difficult to replace its size according to needs. In addition, it is difficult to maintain a single shed when it is damaged and needs to be replaced as a whole. The overall replacement process is very cumbersome and laborious. In addition, due to its relatively fixed structure, the installation position of the shed is also difficult to adjust, which will cause certain limitations in use.

[0024] A cold shrink cable outdoor terminal comprises a three-finger sleeve 1, wherein a cable outer sheath 2 is arranged at the bottom end of the three-finger sleeve 1, an insulating tube 3 is arranged at the top end of the three-finger sleeve 1, a terminal body 4 is arranged on the end of the insulating tube 3 away from the three-finger sleeve 1, a sealing tube 5 is arranged on the end of the terminal body 4 away from the three-finger sleeve 1, a wiring terminal 6 is arranged on the end of the sealing tube 5 away from the terminal body 4, a plurality of sheds 7 are arranged at equal intervals on the outside of the terminal body 4, the sheds 7 are arranged in a staggered manner with large and small intervals, a fixing assembly is arranged below the sheds 7, and the sheds 7 are clamped to the fixing assembly by a clamping assembly.

[0025] The fixing assembly includes an arc-shaped first clamping plate 8 and a second clamping plate 9, one end of the first clamping plate 8 and the second clamping plate 9 are movably hinged through a hinge shaft 10, and rubber cushions 11 are fixedly connected to the inner side walls of the first clamping plate 8 and the second clamping plate 9. An arc-shaped connecting slot 12 is provided at the end of the first clamping plate 8 away from the hinge shaft 10, and an arc-shaped connecting strip 13 is fixedly connected to the end of the second clamping plate 9 away from the hinge shaft 10. The connecting strip 13 and the connecting slot 12 are arranged in corresponding positions and matching specifications. A first connecting hole 14 that penetrates the connecting slot 12 is provided on the end of the first clamping plate 8 close to the connecting slot 12, and a second connecting hole 14 that corresponds to the position of the first connecting hole 14 and matches the specifications is provided on the connecting strip 13. The first and second connecting holes 15 are internally threadedly connected with fixing bolts 16. The fixing assembly can flexibly select the installation position of the umbrella skirt 7 according to needs, so there will be no limitations in use; the clamping assembly includes an arc-shaped clamping strip 17 fixedly connected and symmetrically arranged at the bottom of the umbrella skirt 7, and an arc-shaped clamping groove 18 symmetrically opened on the first clamping plate 8 and the second clamping plate 9 and corresponding to the position of the arc-shaped clamping strip 17 and matching the specifications.

[0026] Workflow: When installing the umbrella skirt 7, firstly, the umbrella skirt 7 needs to be connected to the fixing component through the connecting component. First, the umbrella skirt 7 is placed above the fixing component, and the arc-shaped snap-in strip 17 is pressed hard into the arc-shaped snap-in groove 18 on the first clamping plate 8 and the second clamping plate 9 for snap-in connection. Moreover, since the umbrella skirt 7 and the fixing component are movably snap-in connected, not only can the size of the umbrella skirt 7 be replaced according to needs, but also it is convenient to maintain a single umbrella skirt 7 when it is damaged, without having to replace it as a whole, thus avoiding the cumbersome process of replacing the whole. After the umbrella skirt 7 is connected to the fixing component, the umbrella skirt 7 needs to be installed to a suitable position on the terminal body 4 through the fixing component. First, the first clamping plate 8 and the second clamping plate 9 are moved on the terminal body 4 to adjust the umbrella skirt 7 clamped thereon by the connecting assembly to a suitable installation position, and then the other ends of the first clamping plate 8 and the second clamping plate 9 are brought close to each other through the hinge shaft 10. At this time, the connecting strip 13 on the second clamping plate 9 will be inserted into the connecting slot 12 on the first clamping plate 8. When the first clamping plate 8 and the second clamping plate 9 are completely fitted, the connecting strip 13 is tightly plugged into the connecting slot 12, and the positions of the first connecting hole 14 and the second connecting hole 15 thereon also correspond. Finally, it is only necessary to screw the fixing bolts 16 into the first connecting hole 14 and the second connecting hole 15 to complete the installation of the umbrella skirt 7.
