Technical Field

[0002] Silicone heating wire, also known as silicone heating cable or silicone heating wire, is mainly composed of alloy heating wire and high-temperature silicone rubber insulation cloth. It features fast heating, uniform temperature, high thermal efficiency, and good toughness.
[0003] A series-parallel silicone rubber heating cable, such as one disclosed in CN219267358U, includes an outer ring and a silicone rubber cable body. The silicone rubber cable body is disposed inside the outer ring. A pressure-resistant mechanism for resisting pressure is provided on the outer side of the silicone rubber cable body. A protective component is provided on the outer side of the outer ring. The pressure-resistant mechanism includes a heat-conducting wire fitted onto the outer side of the silicone rubber cable body. A protective ring is fixed to the outer side of the heat-conducting wire, and at least three sleeve rods are fixed to the outer side of the protective ring. This series-parallel silicone rubber heating cable increases the pressure resistance of the silicone rubber cable body by installing a pressure-resistant mechanism on the outer side. The compression of the spring effectively buffers the received pressure, effectively increasing the service life of the silicone rubber cable body. Furthermore, the use of tungsten wire as the heat-conducting wire effectively conducts heat, increasing the electrical conductivity of the silicone rubber cable body.
[0004] The above technical solution has some problems in practical application. The heating wire needs to be bent and laid during use, which may cause the heating wire to crack and affect its use.

Two wire grooves are opened inside the wire body, both of the two wire grooves are set as circular structures, and the two wire grooves are symmetrically arranged. Heating wires are penetrated through the interiors of the two wire grooves. A cavity is penetrated through the middle of the wire body, extension grooves are arranged on both inner walls of the cavity, connection grooves are arranged between the extension grooves and the wire grooves, communication grooves are arranged between the multiple extension grooves. Support blocks are fixedly arranged in the middle of both ends of the wire body, deformation grooves are arranged on both sides of the support blocks, one inner wall of the deformation groove is set as an inclined structure, a first bending groove is opened on the outer side of the support block, and second bending grooves are opened on both sides of the wire body.

[0013] The technical effects and advantages of the present utility model:
[0014] 1. By setting the wire body in the present utility model, the wire body is made of silicone rubber. The good insulation and heat conductivity of silicone rubber can ensure the stable use of the heating wire inside. By setting the first bending groove and the second bending groove on the outer side of the wire body, cross sections of the first bending groove and the second bending groove are both set as isosceles trapezoid structures. The design of the isosceles trapezoid structure enables the wire body to generate a certain range of deformation when bent in both left and right directions, and will not break, thus effectively solving the problem of cracking of the heating wire due to laying and bending.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] The present utility model provides a high-temperature resistant silicone rubber heating wire as Figure 1-3 shown, which includes a wire body 1. The wire body 1 is set as a flat structure, and both sides of the wire body 1 are set as arc structures. The wire body 1 is made of silicone rubber. Two wire grooves 2 are opened inside the wire body 1. Both wire grooves 2 are set as circular structures and are symmetrically arranged. A heating wire 3 is penetrated through the inside of both wire grooves 2. The heating wire 3 is set as a carbon fiber heating body, and the carbon fiber heating body can generate heat after being powered on;
[0022] Specifically, a cavity 4 is penetrated through the middle of the wire body 1. Extension grooves 5 are provided on both inner walls of the cavity 4. A connection groove 6 is provided between the extension groove 5 and the wire groove 2. A communication groove 7 is provided between multiple extension grooves 5. The communication groove 7 can realize the connection between the extension groove 5 and the wire groove 2 to ensure that the air inside the wire body 1 can flow between the wire groove 2 and the extension groove 5, thereby avoiding the internal expansion of the wire body 1 caused by the thermal expansion and contraction of the air. Multiple connection grooves 6 are provided, and multiple connection grooves 6 are arranged at equal intervals. The extension groove 5 and the cavity 4 form a "rich" - shaped structure. The design of the "rich" - shaped structure enables the wire body 1 to expand inward when heated during the heating process of the heating wire, so as to control the range of its thermal expansion and contraction, thereby avoiding the mutual influence between the wire body 1 and the external environment due to thermal expansion and contraction, and ensuring the normal use of the heating wire;
[0023] More specifically, support blocks 8 are fixedly arranged in the middle of both ends of the wire body 1. Deformation grooves 9 are arranged on both sides of the support block 8. One inner wall of the deformation groove 9 is arranged in an inclined structure. A first bending groove 10 is formed on the outer side of the support block 8. Second bending grooves 11 are formed on both sides of the wire body 1. The cross-sections of the first bending groove 10 and the second bending groove 11 are both arranged in an isosceles trapezoid structure. The design of the isosceles trapezoid structure enables the wire body 1 to generate a certain range of deformation when bent in both left and right directions and will not break, thus effectively solving the problem that the heating wire cracks due to laying and bending.
[0024] Working principle of the utility model:
[0025] In the utility model, by arranging the wire body 1 made of silicone rubber, the good insulation and heat conductivity of the silicone rubber can ensure the stable use of the heating wire 3 inside it. By arranging the first bending groove 10 and the second bending groove 11 on the outer side of the wire body 1, the cross-sections of the first bending groove 10 and the second bending groove 11 are both arranged in an isosceles trapezoid structure. The design of the isosceles trapezoid structure enables the wire body 1 to generate a certain range of deformation when bent in both left and right directions and will not break, thus effectively solving the problem that the heating wire cracks due to laying and bending. By arranging the wire body 1, a cavity 4 is arranged in the middle of the wire body 1. Extension grooves 5 are arranged on both sides of the cavity 4. The cavity 4 and the extension grooves 5 form a "rich" structure. The design of the "rich" structure enables the wire body 1 to expand inward when heated during the heating process of the heating wire, so as to control the range of its thermal expansion and contraction, thus avoiding the mutual influence between the wire body 1 and the external environment due to thermal expansion and contraction, and ensuring the normal use of the heating wire.
[0026] Finally, it should be noted that the above are only the preferred embodiments of the utility model and are not used to limit the utility model.
