Description

Technical Field

[0001] This utility model relates to the field of cable accessories, and more particularly to support strips for cold-shrink cable accessories. Background Technology

[0002] Cold shrink cable accessory support strips are support components used in cold shrink cable accessories. Their main function is to support and fix the cable accessories during installation, ensuring that they are evenly pressed against the cable insulation layer during shrinkage. Stable support can reduce the risk of cable terminal failure during operation, thereby improving the safety of the entire cable system.

[0003] A search revealed Chinese Patent Publication No. CN212588072U, which discloses a support strip for cold-shrink cable accessories. By pressing the slider, a spring is compressed, allowing a fixing block to be inserted into a groove. When the slider reaches the slider groove, it pops out. The first rubber pad on the right end of the fixing block engages with the second rubber pad in the groove, thus achieving the purpose of fixing the support strips together. After the support strips are spliced ​​together, they are spirally wound into a cylindrical shape to support the cable accessories. When using the device, the strength of the connected device is greater and the support is more stable.

[0004] In the above technical solution, the support strip is assembled and used to protect the cable by using the cooperation of slider, spring, fixing block and groove. However, the support strip cannot adapt to stress changes and provide constant support and protection for the cable. The cable will vibrate or displace, thereby reducing the stability of the cable operation. Therefore, a cold shrink cable accessory support strip is proposed to solve the above problems.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a cold-shrink cable accessory support strip, including a support strip 1. A support airbag 2 is fixedly connected to the inner wall of the support strip 1. Two sets of support airbags 2 are arranged in a mirror image with respect to the central axis of the support strip 1. An air inlet 3 is provided on the side wall of the support airbag 2. A spring 4 is fixedly connected to the inner wall of the support airbag 2. Several sets of springs 4 are arranged, and the springs 4 are evenly distributed inside each set of support airbags 2. The springs 4 enable the support airbag 2 to automatically reset after being subjected to pressure. A tension band 7 is fixedly connected to the surface of the support airbag 2. A limiting groove 6 is provided on the surface of the support airbag 2. Double-sided adhesive 8 is fixedly connected to the surface of the air inlet 3. A release paper 9 is provided on the side wall of the double-sided adhesive 8. After the release paper 9 is peeled off the double-sided adhesive 8, the double-sided adhesive 8 can adhere to the surface of the tension band 7. A positioning component is provided on the surface of the air inlet 3.

[0033] Reference Figures 3-5The limiting groove 6 is fitted on the outer wall of the tension band 7. The opening of the limiting groove 6 makes the tension band 7 horizontally placed on the surface of the supporting airbag 2. The air inlet 3 is fitted on the outer wall of the tension band 7. A rubber strip 5 is fixedly connected to the outer wall of the supporting airbag 2. The positioning component includes a Velcro 10. The side wall of the Velcro 10 is fixedly connected to the inner surface of the air inlet 3. A Velcro 21 is fixedly connected to the outer wall of the tension band 7. The sides of the Velcro 21 and the Velcro 10 opposite to each other can adhere to each other.

[0034] Reference Figure 5 A fixed cylinder 12 is fixedly connected to the inner wall of the supporting airbag 2. The outer wall of the fixed cylinder 12 is made of insulating material. Magnetic sheet 13 and magnetic sheet 15 on the surface affect the cable. Spring 4 is sleeved on the outer wall of the fixed cylinder 12. A sliding rod 14 is slidably connected to the inner wall of the fixed cylinder 12. Magnetic sheet 15 is fixedly connected to the bottom end of the sliding rod 14. The end of the sliding rod 14 away from the fixed cylinder 12 is fixedly connected to the inner wall of the supporting airbag 2. Magnetic sheet 13 is fixedly connected to the inner wall of the fixed cylinder 12. Magnetic sheet 13 and magnetic sheet 15 are always inside the fixed cylinder 12, and the magnetism on opposite sides of magnetic sheet 13 and magnetic sheet 15 is mutually repulsive. The mutually repulsive magnetism helps spring 4 to quickly return to its original position. The degree to which the sliding rod 14 slides inside the fixed cylinder 12 depends on the degree of compression of the supporting airbag 2. When spring 4 returns to its original position and stretches, the sliding rod 14 simultaneously slides upward inside the fixed cylinder 12.

[0035] Working principle: The support strip 1 is placed over the cable. The tension band 7 is manually pulled, separating the Velcro 10 from the Velcro 21. At this point, the air inlet 3 is mostly removed, and the tension band 7 is no longer compressing the spring 4. The repulsive force between the magnetic sheet 13 and the magnetic sheet 2 causes the slide rod 14 to lift the support airbag 2. After the spring 4 returns to its original position, air fills the support airbag 2. The support airbag 2 gradually expands and adheres to the outer wall of the cable, providing support and protection. When the stress changes, the support airbag 2 can expel or draw in excess air, and the spring 4 will adjust accordingly. During the expansion and contraction deformation, multiple sets of equally distributed rubber strips 5 contact the outer wall of the cable, creating a certain friction between the support airbag 2 and the cable, ensuring the stability of support and protection. When the support strip 1 needs to be disassembled, the tension band 7 is manually pulled diagonally downwards. Due to the adhesion of the double-sided adhesive 8, the tension band 7 pulls the top of the air inlet 3 downwards. The continuous downward movement of the tension band 7 can compress the spring 4. When the Velcro 2 11 approaches the Velcro 1 10, the support airbag 2 will be in a relatively compressed state, creating a gap between the cable and the support airbag 2, making it convenient to disassemble the support strip 1.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
