Description

Technical Field

[0001] This utility model relates to the field of gasket technology, and more particularly to a conductive insulating gasket. Background Technology

[0002] The use of gaskets in sealing applications is commonplace in many industries. Gaskets are well-known for providing a fluid seal between two mating surfaces (e.g., between the ends of adjacent pipes or conduits), which are typically in the form of flanges to facilitate assembly and disassembly and to ensure a better seal.

[0003] Currently, in existing technologies, thermally conductive insulating gaskets are relatively thin electrical insulating sheets, usually made of silicone rubber, with a thickness typically ranging from 0.1mm to 0.3mm. Existing gaskets mainly include plastic gaskets and rubber gaskets. Compared to plastic gaskets, rubber gaskets have insufficient impact resistance, while rubber gaskets have too low an elastic modulus and insufficient stiffness. Furthermore, their simple structure makes it difficult for them to effectively distribute pressure, which can easily lead to separation and detachment between the layers of the gasket body, greatly reducing their efficiency.

[0004] Existing technology has flaws and needs improvement. Utility Model Content

[0005] In order to overcome the shortcomings of the current technology, this utility model provides a conductive insulating pad.

[0010] Preferably, the gasket body further includes a rectangular reinforcing block, the rectangular reinforcing block is disposed inside the first fastening cavity, and the bottom end of the rectangular reinforcing block extends to the outside of the first fastening cavity and is fixedly connected to the second insulating layer.

[0011] Preferably, the first insulating layer, the second insulating layer, and the central core are all circular structures, and the material of the central core is an insulating material.

[0012] Preferably, the second insulating layer further includes a first heat-conducting sheet and a second heat-conducting sheet, which are disposed on both sides of the second insulating layer, and both the first heat-conducting sheet and the second heat-conducting sheet are annular.

[0013] Preferably, the outer surface of the central core is further coated with an anti-corrosion layer.

[0014] Preferably, the upper surface of the central core protrudes from the surface of the first insulating layer to form a raised sealing surface, and the sealing surface is set as an arc surface.

[0015] Preferably, both the first insulating layer and the second insulating layer can be made of silicone.

[0016] Compared with the advantages of existing technologies, the first insulating layer, the second insulating layer, and the central core with holes in this utility model not only reduce the phenomenon of separation and detachment of the first insulating layer and the second insulating layer at both ends of the outer surface of the gasket base layer, thus ensuring the service life of the insulating gasket, but also ensure the sealing effect of the gasket during use, and improve the insulation and wear resistance of the gasket.
