Description

Technical Field

[0001] This utility model relates to the field of cold shrink indoor terminal technology, and in particular to a cold shrink indoor terminal device with adaptive stress dispersion. Background Technology

[0002] Cold shrink indoor terminals utilize cold shrink technology to tightly wrap the insulation material around the cable, forming a complete sealed structure. During installation, no heating or open flame is required. Simply pull out the internal supporting plastic spiral strip or support, and it will automatically shrink and reset, tightly clamping onto the cable body. This makes the installation process simple and quick.

[0003] In the prior art, cold shrink indoor terminals are crucial for cables. They not only provide necessary electrical connections and mechanical protection, but also enhance the reliability and durability of the cable system. During installation, they are easily affected by factors such as material quality, installation process, and environmental factors, which can affect the installation stability of the cold shrink indoor terminal and thus directly affect its performance. A search revealed a utility model of a cable cold shrink indoor terminal with application number CN202322314154.5, which also suffers from the above-mentioned problems. Utility Model Content

[0005] To achieve the above objectives, an adaptive stress-dispersing cold-shrink indoor terminal device is provided, comprising a cable outer body, within which multiple outer cable bodies are fixed in an array, and inner cable bodies are fixed between the multiple outer cable bodies. A right shroud is nested at the right end of the cable outer body, and a left shroud is nested at the left end of the cable outer body.

A support rod is fixed between the two support plates. Both ends of the support rod extend to the outside of the support plate. Clamping plates are nested at both ends of the support rod. The clamping plates on both sides are connected to the left partition by a fixed bolt thread.

[0006] According to the adaptive stress dispersion cold shrink indoor terminal device, two dispersion components are provided on the outside of each of the plurality of cold shrink tubes.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4This utility model discloses an adaptive stress-dispersing cold-shrink indoor terminal device, which includes a cable outer body 1. Multiple outer cable bodies 2 are fixedly arranged in an array inside the cable outer body 1. Inner cable bodies 3 are fixed between the multiple outer cable bodies 2. A right partition 4 is nested at the right end of the cable outer body 1, and a left partition 5 is nested at the left end of the cable outer body 1. A cold-shrink indoor terminal assembly is disposed on the left side of the left partition 5. The cold-shrink indoor terminal assembly includes multiple spiral strips 6, all of which are disposed on the left side of the left partition 5. On one side, multiple spiral strips 6 are fixed with cold shrink tubing 7 on their left side. The right side of the cold shrink tubing 7 extends into the interior of the left partition 5. A contact 8 is fixed to the left end of the cold shrink tubing 7. A reinforcing assembly is sleeved on the outside of the multiple cold shrink tubing 7. The reinforcing assembly includes a reinforcing circular plate 9. Support plates 10 are fixed to both ends of the bottom of the reinforcing circular plate 9. The right sides of the two support plates 10 are fixedly connected to the left side of the left partition 5. A support rod 11 is fixed between the two support plates 10. Both ends of the support rod 11 extend to the outside of the support plate 10 and are nested at both ends. There are clamping plates 12, and both sides of the clamping plates 12 are threadedly connected to the left partition 5 by fixing bolts 13. In the prior art, cold shrink indoor terminals are crucial for cables. They not only provide necessary electrical connections and mechanical protection, but also enhance the reliability and durability of the cable system. During installation, they are easily affected by factors such as material quality, installation process, and environmental factors, which can affect the installation stability of the cold shrink indoor terminal and thus directly affect the performance of the cold shrink indoor terminal. To address this issue, a reinforcing component can be fitted around multiple cold shrink tubes 7. That is, during the installation of the cold shrink indoor terminal component, multiple cold shrink tubes 7 are fixed to the left partition 5 by setting up a reinforcing circular plate 9, a support plate 10, a support rod 11, clamping plates 12, and fixing bolts 13. The support rod 11 and the two clamping plates 12 form an arched structure to clamp the support plate 10 on both sides, thereby maintaining the multiple cold shrink tubes 7 in the cold shrink indoor terminal component to form a stable structure and improving subsequent usage efficiency.

[0024] Two dispersion components are provided on the outside of each of the multiple cold shrink tubes 7. The two dispersion components are the same size and each dispersion component includes a dispersion corner block 14. A dispersion column 15 is fixed between adjacent dispersion corner blocks 14. By setting two dispersion components, that is, designing multiple dispersion corner blocks 14 and dispersion columns 15, the force on the outside of the multiple cold shrink tubes 7 can be dispersed, thereby improving the adaptive stress dispersion effect.

[0025] Each adjacent outer cable body 2 is fixed with a connecting arc block 16. The multiple connecting arc blocks 16 are of the same size, which improves the connection effect between adjacent outer cable bodies 2. Each of the multiple dispersion corner blocks 14 has a protective ring 17 fixed inside. The multiple protective rings 17 are all set outside the cold shrink tube 7 to avoid the dispersion corner blocks 14 from causing wear to the outside of the cold shrink tube 7. The cable outer body 1 is fitted with a heat dissipation cover 18. The heat dissipation cover 18 has multiple heat dissipation holes 19 that run horizontally through the outside of the heat dissipation cover 18, thereby promoting the concentrated dissipation of heat inside the cable outer body 1 and improving the heat dissipation effect.

[0026] Both dispersion components are designed with an angular structure. The stability of the angular structure is used to improve the dispersion effect of the dispersion components. The sides of the clamping plates 12 are arc-shaped, which can better nest the support rods 11 and strengthen the stability of the support rods 11. The cable outer body 1 is fitted with a reinforcing ring 20. The heat dissipation cover 18 is set between the two reinforcing rings 20, and the bottom of the reinforcing rings 20 is fixed with a reinforcing platform 21, which can support the cable outer body 1 and prevent external abrasion.

[0027] Working principle: To reduce the impact of external factors on the installation stability of the cold shrink indoor terminal, a reinforcing component can be attached to the outside of multiple cold shrink tubes 7. During the installation of the cold shrink indoor terminal component, multiple cold shrink tubes 7 are fixed to the left partition 5 by setting up a reinforcing circular plate 9, a support plate 10, a support rod 11, a clamping plate 12, and a fixing bolt 13. The support rod 11 and the two clamping plates 12 form an arched structure to clamp the support plate 10 on both sides, thereby maintaining the multiple cold shrink tubes 7 in the cold shrink indoor terminal component to form a stable structure and improving subsequent use efficiency. Furthermore, by setting up two dispersion components, namely designing multiple dispersion corner blocks 14 and dispersion columns 15, the forces externally applied to the multiple cold shrink tubes 7 can be dispersed, improving the adaptive stress dispersion effect.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
