Description

Technical Field

[0001] The utility model belongs to the technical field of adhesive tapes, and in particular relates to an electrically conductive and thermally conductive adhesive tape. Background Art

[0002] During the use of the conductive tape, the inside of the conductive tape is mostly conductive strips. When cutting, it is not convenient to cut due to the high hardness of the conductive strips. Although the thin conductive strips are easy to cut, their conductivity is not high, which can easily cause power outages. Among them, the "a conductive and thermally conductive tape that is easy to cut" disclosed in the application number "CN202023051815.2" is also an increasingly mature technology. It has good stability and safety when connected through conductive wiring. At the same time, the outer side of the boss is fixed with an inner cover plate through the cooperation of a limit block and a limit groove. The bottom end of the inner cover plate is provided with a conductive end connected to the conductive wire plate. When cutting, the inner cover plate can be directly taken out to disconnect the middle part of the conductive wire plate, thereby facilitating cutting. However, the device also has the following defects: when the above-mentioned device is used, when the tape is attached to the surface of an object, the waterproof performance is not high. After the adhesive layer contacts water vapor, it can not only affect the viscosity of the adhesive but also affect the conductivity. When used, it needs to contact the surface of the object for conduction. The contact surface of the above-mentioned device is limited, and the conductive effect is limited. Utility Model Content

[0006] In this solution, the thermally conductive insulating layer is protected by a protective film to prevent scratches on the surface of the thermally conductive insulating layer from affecting the thermal conductivity and insulation effects.

[0013] In an implementation scheme of the conductive and thermally conductive tape of the utility model, the thermally conductive insulating layer is made of conductive silicone material.

[0014] In this solution, the thermally conductive insulating layer is used to isolate the current and conduct the heat.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1) When the surface of an object is bonded by the provided waterproof foam adhesive and the conductive adhesive layer, the base metal foil leaks out from the through groove and directly contacts the surface of the object to conduct electricity.
