Description

Technical Field

[0001] The utility model relates to the technical field of heat shrink tubes, in particular to an anti-falling industrial silicone heat shrink tube. Background Art

[0002] Silicone heat shrink tubing is a heat shrinkable silicone tube made from modified silicone rubber. It not only inherits the excellent properties of the silicone tube itself, such as high temperature resistance, high pressure resistance, softness and elasticity, but also has heat shrinkage properties and good mechanical properties of resistance to puncture damage. These characteristics make silicone heat shrink tubing widely used in industry and become an indispensable and important material in the industrial field.

[0003] In industrial applications, heat shrink tubes are often used to protect the joints between wires. However, the current common practice is to put the heat shrink tube on the wire joints and then heat it to shrink the heat shrink tube to strengthen the protection. However, with long-term use, the heat shrink tube will deform and become loose, and the heat shrink tube does not have a good pulling effect on the two wires, and may even fall off from the wire joints, causing the wires to break.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-5As shown, the utility model provides an anti-falling industrial silicone heat shrink tube, which is mainly used to protect wire joints in industry. While preventing them from falling off, it also well protects the connection between the wires and can also improve the sealing of the wire joints. Its specific structure mainly includes a pipe sleeve 1 that is internally conductive with both sides, a raised portion 2 is provided in the middle of the pipe sleeve 1, two wires are respectively inserted into the raised portion 2 from the openings on both sides of the pipe sleeve 1, and the connection position of the two wires is arranged on the inner side of the raised portion 2, and then the entire pipe sleeve 1 is tightened by hot baking, and after tightening, the connection between the wires is strengthened by the internal structure of the raised portion 2, and the wires are prevented from falling off.

[0022] The inner wall of the raised portion 2 is provided with a coaxial and tightly fixed nickel ring 3 and two sealing rings 4. The two sealing rings 4 are distributed on both sides of the nickel ring 3 along the extension direction of the pipe sleeve 1. A nickel ring 3 connected to the wire connection after extrusion is added in the raised portion 2. On the one hand, it can strengthen the fixation of the wire connection, and on the other hand, it can also strengthen the conductivity of the connection to prevent the wire from being disconnected and unable to be energized when the two ends are pulled. In order to better fix the position of the nickel sheet 3, a first clamping groove 7 for clamping the nickel sheet 3 is added to the inner wall of the raised portion 2. In addition, a sealing ring 4 for strengthening internal friction and anti-skid is also added in the raised portion 2. The sealing ring 4 increases friction with the wire through the anti-skid convex particles 4 on the inside, and the outer side forms a convex deformed structure with the pipe sleeve 1 after hot baking, which has a good reinforcement effect and prevents the wire from being pulled out. At the same time, in order to better fix the position of the sealing ring 4, a second clamping groove 8 for clamping the sealing ring 4 is also added to the inner wall of the raised portion 2. At the same time, the position where the sealing ring 4 is assembled on the raised portion 2 also bulges outward.

[0023] Double-sided adhesive layers 5 are provided at the openings on both sides of the tube sleeve 1 and are adhered to the inner wall. One side of the double-sided adhesive layer 5 at the opening is adhered to the inner wall of the tube sleeve 1, and the other side is adhered to the surface of the wire. When the tube sleeve 1 shrinks to a certain extent, the double-sided adhesive layer 5 automatically seals the opening. Similarly, its own adhesive force prevents the tube sleeve 1 from falling off and the wire from being pulled out.

[0024] The outer layer of the raised portion 2 is also covered with a plastic sleeve 6, and the two ends of the plastic sleeve 6 are clamped and fixed with the sealing ring 4. The plastic sleeve 6 is fixed on the surface of the wire connection after heat shrinkage, which can strengthen the protection of the wire connection in the pipe sleeve 1 to prevent the impact of external forces. In order to better fix the plastic sleeve 6, the inner walls on both sides of the plastic sleeve 6 are provided with a third clamping groove 10 clamped and fixed with the raised part of the sealing ring 4. In order to better cover the plastic sleeve 6 on the surface of the pipe sleeve 1, the plastic sleeve 6 is provided with an opening portion 11 consistent with the extension direction. The user only needs to open the opening portion 11 to smoothly cover the surface of the pipe sleeve 1. At this time, the plastic sleeve 6 is not easy to break when the opening portion 11 is pried open.

[0025] Compared with the traditional technology, the present technical solution adds a nickel ring 3 which is combined with the wire connection after extrusion inside the raised portion 2 of the sleeve 1. The nickel ring 3 can not only enhance the conductivity but also reinforce the connection position between the wires to prevent disconnection. The sealing ring 4 on the inner side of the raised portion 2 and the double-sided adhesive layer 5 at the opening of the sleeve 1 can enhance the stability of the wire in the sleeve 1 and prevent the wire from being pulled out. Finally, the plastic sleeve 6 on the surface of the sleeve 1 further fixes and protects the position of the wire connection.

[0026] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
