Description

Technical Field

[0001] The utility model relates to the technical field of power distribution equipment, in particular to a special soft high temperature resistant silicone wire for power distribution equipment. Background Art

[0002] The most notable feature of silicone wire is its high-temperature stability. Although the strength of silicone rubber at room temperature is only half of that of natural rubber or some synthetic rubber, in a high-temperature environment above 200°C, silicone rubber can still maintain a certain flexibility, resilience and surface hardness, and its mechanical properties do not change significantly. It is widely used in power distribution equipment.

[0003] The existing patent CN216902326U, a document on a silicone wire, proposes that the utility model wraps the copper stranded wire with a silicone sleeve and a protective sleeve, and the two are connected by a snap-fit ​​part, which can prevent the copper stranded wire from bending, moving and breaking, thereby improving the bending resistance of the silicone wire, which is beneficial for use in electrical devices.

[0004] However, the existing patent CN216902326U does not propose a technical solution for the heat dissipation of the silicone wire. The copper wire inside the silicone wire may cause high temperature and catch fire due to excessive current. In addition, during the installation of the silicone wire, there is no good fixing mechanism, which is not convenient for the fixed installation of the silicone wire. Utility Model Content

[0025] The protective mechanism 2 includes a silicone rubber 201, a moisture-proof layer 202 and an anti-wear layer 203. The silicone rubber 201 is fixedly installed on the outer end of the thermal conductive silicone 103, the moisture-proof layer 202 is fixedly installed on the outer end of the silicone rubber 201, and the anti-wear layer 203 is fixedly installed on the outer end of the moisture-proof layer 202. Through the installation of the silicone rubber 201, the silicone wire has excellent insulation performance, corona resistance and arc resistance, and has good flexibility. Through the installation of the moisture-proof layer 202, the water vapor machine is prevented from entering the interior of the silicone wire, and the oxidation of the tinned copper wire 101 is prevented. Through the anti-wear layer 203, the surface of the silicone wire is not easily scratched.

[0026] The heat dissipation mechanism 3 includes a heat sink 301, an inner connection hole 302 and an outer connection hole 303.

The inner connection hole 302 is fixedly arranged at the inner end of the heat sink 301, and the outer connection hole 303 is fixedly arranged at the outer end of the heat sink 301. When the tinned copper wire 101 releases heat, the heat is transferred to the heat sink 301 through the thermal conductive silicone 103, so that the heat sink 301 transfers the heat to the outside of the silicone wire to dissipate heat and cool the inside of the silicone wire.

[0028] Working principle: The high temperature resistant flame retardant filling layer 102 can prevent the tinned copper wire 101 from catching fire due to excessive current.

The heat generated by the tinned copper wire 101 is transferred to the heat sink through the thermal conductive silicone 103. 301, so that the heat sink 301 transfers heat to the outside of the silicone wire, dissipates heat and cools the inside of the silicone wire. The heat sink 301 is semicircular, which is convenient for bending the silicone wire. The installation of the inner connecting hole 302 and the outer connecting hole 303 facilitates the connection between the heat sink 301 and the protective mechanism 2 to be more stable. When the silicone wire is to be installed, the suction cup 403 of the silicone wire is pressed at a suitable position to squeeze out the air in the inner groove 404 inside the suction cup 403, thereby forming a negative pressure inside the suction cup 403, so that the suction cup 403 is adsorbed on the installation surface, thereby facilitating the installation and removal of the silicone wire.
