Description

Technical Field

[0001] The utility model belongs to the field of connection terminals, and in particular relates to a connection terminal of a graphene heating film strip. Background Art

[0002] The graphene heating film is a flat structure, and its internal power supply needs to be provided by a flat copper strip. How to connect the copper strip to the external wire is a difficult problem. The traditional method is to pierce the heating film with a puncture nail so that the puncture point between the puncture nail and the copper strip is in contact and conductive, but the contact area of ​​the puncture nail is small, and the contact may be poor when working with large currents.

[0003] In the prior art, for example, a heating film structure for building floors disclosed in Chinese patent CN220935334U increases the contact area between the conductive terminal and the heating film by peeling off the protective film at the contact position between the top of the heating film and the conductive terminal in order to improve the conductivity of the heating film structure. However, in the prior art, the connection between the conductive terminal and the conductive copper strip is not tight enough, which easily leads to poor contact. Utility Model Content

[0004] The utility model aims to provide a connection terminal of a graphene heating film strip, so as to solve the problem that the connection tightness between the conductive terminal and the conductive copper strip in the prior art is insufficient, and poor contact is easily caused.

[0005] To this end, the utility model provides a connecting terminal for a graphene heating film strip, comprising: a terminal body, a slot provided on the terminal body, a conductive sheet provided in the slot, an elastic clip provided in the terminal body, and an elastic clip provided on the outside of the terminal body, wherein the elastic clip is used to clamp the terminal body to compress the space of the slot.

[0007] Preferably, a fixing groove is provided on the end surface of the slot, and one end of the conductive sheet is inserted into the fixing groove.

[0008] Preferably, the length of the conductive sheet is longer than the slot. The conductive sheet separates the graphene heating film and is inserted into the graphene heating film to connect with the conductive copper tape in the graphene heating film. The graphene heating film is inserted into the slot to increase the contact area between the conductive copper tape and the conductive sheet, thereby increasing the current passing through the graphene heating film.

[0009] Preferably, a wire is provided in the terminal body, and one end of the wire is connected to the conductive sheet in the fixing groove.

[0010] Preferably, the elastic clip comprises a connecting portion and a clamping portion, the clamping portion has two symmetrically arranged at both ends of the connecting portion, the clamping portion is provided with a clamping portion at one end of the connecting portion, and the clamping portion is arranged obliquely. The elastic clip is integrally formed and has high elasticity. When in use, the terminal body spreads the two clamping portions apart, and due to the elastic force of the clamping portion, the clamping portion generates a clamping force on the terminal body, further increasing the close connection between the conductive sheet and the conductive copper strip, and preventing poor contact between the conductive sheet and the conductive copper strip.

[0011] Preferably, it further comprises a clamping force adjustment block, which is arranged on the outer side wall of the terminal body, and cooperates with the elastic clip to adjust the clamping force of the fixed clip.

[0012] Preferably, the clamping force adjustment block includes a plurality of step grooves, the heights of the step grooves are arranged in order from high to low, and the clamping portion is connected with the step grooves in a coordinated manner. Different clamping forces can be adjusted by the clamping force adjustment block to adapt to the connection of graphene heating films of different thicknesses.

[0013] Preferably, the conductive sheet is made of copper.

[0014] Preferably, the terminal body is made of insulating plastic.

[0015] Beneficial effects:

[0016] 1. The utility model provides a connection terminal for a graphene heating film strip, which can clamp the terminal body to compress the space of the slot through an elastic clip, thereby improving the tightness of the connection between the conductive sheet and the conductive copper strip.

[0017] 2. In the utility model, the conductive sheet separates the graphene heating film and is inserted into the graphene heating film to connect with the conductive copper tape in the graphene heating film. The graphene heating film is inserted into the slot to increase the contact area between the conductive copper tape and the conductive sheet, thereby increasing the current passing through the graphene heating film.

[0018] 3. The elastic clip in the utility model is integrally formed and has high elasticity. When in use, the terminal body stretches the two clamping parts apart. Due to the elastic force of the clamping parts, the clip parts will generate clamping force on the terminal body, further increasing the close connection between the conductive sheet and the conductive copper strip, and preventing poor contact between the conductive sheet and the conductive copper strip.

[0019] 4. In the utility model, the clamping force adjustment block cooperates with the elastic clip to adjust the clamping force of the fixed clip, the height of the step groove is arranged from high to low, and the clip part is connected with the step groove.
