Description

Technical Field

[0001] The utility model relates to a conductive adhesive tape, in particular to a composite heat dissipation conductive adhesive tape, belonging to the technical field of conductive adhesive tapes. Background Art

[0002] Conductive tape is a product that makes a conductive medium into a conductive tape. It has the characteristics of good softness, strong adhesion, good conductivity, etc. It is widely used in anti-shielding applications, has better conductivity than metal and is easy to process and operate. Conductive tape is a metal foil or conductive cloth with a highly conductive backing adhesive. Its conductive backing adhesive and conductive substrate form a complete conductor, which can be bonded to any metal surface to complete electrical overlap and electrical sealing of gaps. Conductive tape is an economical and easy-to-use shielding material.

[0003] The existing utility model patent with announcement number CN206318931U discloses a conductive tape, which is sequentially stacked with a release protective layer, an inorganic and organic composite conductive layer, an adhesive layer and a conductive substrate layer. The adhesive layer contains a plurality of conductive particles mixed in the adhesive, and the inorganic and organic composite conductive layer has a through-hole array, so that some conductive particles enter the through-hole array along with the adhesive, thereby solving the problem of unstable conductive performance of the prior art and having the effect of stably improving conductive performance.

[0004] Its structure is composed of multiple layers stacked together, which has a certain shielding effect on heat. However, due to its general heat dissipation performance, when it is attached to electrical components, it may cause heat concentration and affect the heat dissipation of the overall circuit of the electrical components. Therefore, a composite heat dissipation conductive tape is proposed to address the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a composite heat dissipation conductive tape, which can work in combination with a thermally conductive adhesive layer and auxiliary heat dissipation holes to dissipate the heat of the conductive material inside the conductive tape during operation, and can also dissipate the working heat of electrical components at the installation location, and can effectively avoid heat accumulation at the installation location of the tape, thereby solving the technical problem in the prior art that the conductive tape has a poor heat dissipation effect that may affect the overall heat dissipation of the circuit.

[0006] In order to solve the above problems, the following technical solutions are provided:

[0007] A composite heat dissipation conductive tape is designed, comprising a tape body, wherein a plurality of equally spaced auxiliary heat dissipation holes are centrally opened on the tape body along the length direction, a peeling layer is pasted on the lower end surface of the tape body, the tape body comprises a centrally arranged middle substrate strip and two side substrate strips respectively arranged on both sides of the middle substrate strip, a conductive cloth strip is sandwiched between the middle substrate strip and the side substrate strips, the upper end surfaces of the middle substrate strip, the side substrate strip and the conductive cloth strip are all bonded with a thermal conductive adhesive layer, and the lower end surfaces of the middle substrate strip, the side substrate strip and the conductive cloth strip are all bonded with a conductive adhesive layer.

[0008] The above-mentioned structural form can form a complete thermal conductivity and heat dissipation path by combining the auxiliary heat dissipation holes and the thermal conductive adhesive layer, which can efficiently dissipate the heat generated by the conductive cloth strips and the conductive adhesive layer during conduction, and can also efficiently dissipate the heat of the electrical components at the mounting location, thereby effectively avoiding heat concentration in the circuit.

[0009] Furthermore, a porous surface layer is evenly attached to the upper end surface of the thermally conductive adhesive layer, and the porous surface layer is a wear-resistant porous non-woven fabric layer structure.

[0010] The above structural form can protect the tape body through the porous surface layer, and the porous structural form does not affect heat dissipation.

[0011] Furthermore, the upper end surface of the middle substrate strip is provided with a plurality of uneven first bonding lines along the length direction, and the portion of the lower end surface of the thermal conductive adhesive layer that contacts the first bonding lines is formed with bonding teeth.

[0012] The above structural form can increase the bonding area between the middle substrate strip and the thermal conductive adhesive layer through the first bonding lines and the bonding teeth, thereby improving the firmness of the bonding between the two.

[0013] Furthermore, the upper end surface of the side substrate strip is provided with a plurality of uneven second bonding lines along the length direction, and the portion of the lower end surface of the thermal conductive adhesive layer that contacts the second bonding lines is formed with bonding teeth.

[0014] The above structural form can increase the bonding area between the side substrate strip and the thermal conductive adhesive layer through the second bonding lines and the bonding teeth, thereby improving the firmness of the bonding between the two.

[0015] Furthermore, the middle portion of the conductive adhesive layer is not connected along the length direction to form a centrally arranged gap, and the width of the gap is smaller than the width of the middle substrate strip.

[0016] The above structure can form a heat dissipation path with the gap, and the width of the gap is smaller than the width of the middle substrate strip, which can ensure that the conductive adhesive layer can bond the lower end surface of the middle substrate strip and the conductive cloth strip together.

[0017] Furthermore, the tape body is provided with a plurality of groups of transversely arranged tear holes along the length direction, and all the tear holes in each group of tear holes are distributed on the same straight line.

[0018] The above structural form can facilitate the user to tear off the tape body of a fixed distance along the tear hole.

[0019] Furthermore, the porous surface layer, the thermal conductive adhesive layer and the middle substrate strip are all provided with auxiliary heat dissipation holes of the same size and position.

[0020] The above structural form can ensure that heat can be transferred from the inside to the outside.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] In the utility model, the auxiliary heat dissipation holes and the thermally conductive adhesive layer are provided, and the two work in combination to form a complete thermally conductive heat dissipation path, which can efficiently conduct away the heat released by the conductive cloth strips and the conductive adhesive layer due to the conversion of electric energy when power is turned on, and can also efficiently conduct away the heat of the electrical components where they are mounted. The auxiliary heat dissipation holes are opened in the middle to avoid the concentration of heat in the middle. BRIEF DESCRIPTION OF THE DRAWINGS
