Description

Technical Field

[0001] The utility model relates to the field of braided sleeves, in particular to a double-layer heat-shrinkable braided sleeve. Background Art

[0002] Heat-shrinkable braided tubing is made of polyester fiber and polyolefin monofilament. This material can shrink to 0.5 times its original inner diameter after being heated. This tubing has excellent noise reduction, flexibility, wear resistance and heat insulation. It is widely used in automotive hoses, plastic pipes and wires. It can protect pipelines, prevent damage and reduce noise.

[0003] After searching, the application number is "202222166520.2", which provides a double-layer heat shrinkable braided sleeve, which includes a hot melt adhesive layer and a braided layer constructed from the inside to the outside, and the hot melt adhesive layer partially or completely covers the inner surface of the braided layer. The braided layer is woven from polyester fiber multifilament and polyolefin monofilament based on a weft density range of 10-20.

[0004] The above-mentioned method prevents slippage and affects the realization of protection function by coating the inner layer of the heat shrinkable braided sleeve with hot melt adhesive, and also plays a waterproof function. However, the inner layer of the heat shrinkable braided sleeve is provided with a braided layer, which helps electrical heat conduction. After coating with hot melt adhesive, the thermal conductivity effect decreases, making it difficult to discharge the heat emitted by the protected wires, and long-term use is likely to affect the heat dissipation of the wires.

[0008] According to the double-layer heat shrinkable braided sleeve, the heat dissipation silicone block is arranged in an arc-shaped structure to play a protective role.

[0009] According to the double-layer heat shrinkable braided sleeve, there are multiple heat dissipation silicone blocks.

[0010] According to the double-layer heat shrinkable braided sleeve, the number of the heat dissipation holes is multiple.

[0011] According to the double-layer heat shrinkable braided sleeve, the plurality of heat dissipating silicone blocks are distributed in a circular array structure.

[0012] Beneficial effects:

[0013] By providing a heat-conducting component, the heat-dissipating silicone block, heat-dissipating holes and grooves can dissipate heat from the heat-shrinkable braided sleeve body coated with a hot-melt adhesive coating, so that the heat of the protected wires can be quickly discharged to avoid affecting the use of the wires.

[0021] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0022] Reference Figure 1-3 A double-layer heat shrinkable braided sleeve comprises a heat shrinkable braided sleeve body 1: the inner layer of the heat shrinkable braided sleeve body 1 is provided with a heat conductive component 3, wherein the heat conductive component 3 increases the thermal conductivity of the heat shrinkable braided sleeve body 1, so as to protect the wires.

[0023] The heat-conducting component 3 includes a heat-dissipating silicone block 301, which is fixedly connected to the inner layer of the heat-shrinkable braided sleeve body 1. A plurality of heat-dissipating holes 302 are provided on the outer side of the heat-dissipating silicone block 301, and a groove 303 is provided on the lower side of the heat-dissipating silicone block 301. A hot-melt adhesive coating 2 is coated on the inner side of the heat-shrinkable braided sleeve body 1 and between the two heat-dissipating silicone blocks 301. The heat-dissipating silicone block 301 is arranged in an arc-shaped structure, and there are multiple heat-dissipating silicone blocks 301, and there are multiple heat-dissipating holes 302. The multiple heat-dissipating silicone blocks 301 are distributed in a circular array structure. When in use, the heat-shrinkable braided sleeve body 1 It is sleeved on the outside of the wire, and then the heat shrinkable braided sleeve body 1 is heated. At this time, the heat shrinkable braided sleeve body 1 shrinks, and the heat shrinkable braided sleeve body 1 drives the arc-shaped heat dissipation silicone block 301 to fit closely to the outside of the wire. At this time, due to the high temperature, the hot melt adhesive coating 2 contacts the outside of the wire, which plays an anti-slip and waterproof role. When in use, due to the heat dissipation holes 302 and the grooves 303, there are gaps between the wire and the heat dissipation silicone block 301. The wire discharges heat through these gaps and conducts heat through the heat dissipation silicone block 301, thereby increasing the thermal conductivity of the heat shrinkable braided sleeve body 1 and avoiding damage to the wire.

[0024] Working principle: When in use, the heat shrink braided sleeve body 1 is put on the outside of the wire, and then the heat shrink braided sleeve body 1 is heated to make the heat dissipation silicone block 301 close to the wire, and the heat dissipation holes 302 and the grooves 303 are opened to discharge the heat emitted by the wire, and the heat is conducted out through the heat dissipation silicone block 301, which is convenient for normal heat dissipation of the wire.

[0025] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
