[0002] Epoxy heating plate is an electric heating device made of epoxy resin material. Epoxy resin is a polymer material with good insulation performance and mechanical strength. It is often used to make insulating parts and structural parts of various electrical equipment. Existing epoxy heating plates are usually made of epoxy resin combined with resistance wire (such as nickel-chromium alloy wire) or other electric heating elements. The resistance wire is embedded or adhered to the epoxy board, and the two ends are connected to the positive and negative poles of the power supply respectively.

DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of the utility model.

[0025] like Figure 1-6 As shown, this embodiment discloses an epoxy heating plate, including an upper epoxy resin layer 1 and a lower epoxy resin layer 2, wherein a conductive heating layer 3 is provided between the upper and lower epoxy resin layers 2, wherein the conductive heating layer 3 includes a base layer 31 mixed with a conductive substance, wherein the conductive substance may be carbon black, which has high conductivity. When carbon black is added to the base layer 31 made of epoxy resin, the base layer 31 can be made conductive.

[0026] like Figure 2 As shown, a mounting groove 6 is provided on one side of the base layer 31 relative to the upper epoxy resin layer 1, and a pair of electrode strips 32 are provided in the mounting groove 6. The pair of electrode strips 32 are arranged to penetrate the base layer 31 horizontally, and the two ends thereof are exposed at the two sides of the base layer 31 to form connecting ends 33. A clamping piece A34 and a clamping piece B35 are provided at the positions corresponding to the positions of the connecting ends 33 on the two sides of the base layer 31, and the clamping piece A34 and the clamping piece B35 can be clamped and matched, and also include a power line 36 electrically connected to the connecting ends 33 of the pair of electrodes, and one end of the power line 36 is provided There is a connector 37 that is clamped with the clamp A34. The power cord 36 can be connected to the connection end 33 at one end of the two electrode strips 32 through the connector 37. When the two power cords 36 are respectively connected to the positive and negative poles of the power supply, the two electrode strips 32 are connected through the base layer 31 mixed with carbon black, so that the conductive heating layer 3 is energized to generate heat, thereby transferring heat to the outside. The entire conductive heating layer 3 is heated, which can better enable the conductive epoxy resin layer to be energized to generate heat, and can transfer heat to the outside evenly and comprehensively. The heating efficiency is high and the heating effect is good.

[0027] like Figure 2 As shown, a plurality of branch electrodes 4 are arranged on the opposite side of the two electrode strips 32 , and the branch electrodes 4 on the two electrode strips 32 are spaced apart and staggered. The branch electrodes 4 spaced apart from each other on the two electrode strips 32 can form multiple conductive paths on the conductive heating layer 3 .

[0028] like Figure 4-6As shown, the clamping member A34 includes a pair of clamping blocks 341 arranged on one side of the base layer 31 and located on both sides of the connecting end 33, and a connecting groove 342 is provided on the side of the clamping block 341 away from the base layer 31; the clamping member B35 includes a pair of clamping plates 351 arranged on the other side of the base layer 31 relative to the clamping member A34, and a connecting head 352 slidably matched with the connecting groove 342 is provided on the side of the clamping plate 351 away from the base layer 31, and the connecting groove 342 and the connecting head 352 are both arrow-shaped and can be clamped together; and the connecting member 37 of the power cord 36 includes a mounting plate 371 connected to the power cord 36, and an electrode plate 372 connected to the power cord 36 is provided on the mounting plate 371, and connecting clamping heads 373 slidably matched with a pair of connecting grooves 342 are provided on both sides of the electrode plate 372 of the mounting plate 371.

[0029] When the user needs to assemble multiple epoxy heating plates, the user first connects the clamp A34 of one of the epoxy heating plates to the mounting plate 371 connected to the power cord 36, wherein a pair of connecting clamps 373 on the mounting plate 371 will be stuck in the connecting groove 342, and the electrode plate 372 will abut against the connecting end 33 of the electrode strip 32, thereby realizing the connection between the power cord 36 and the electrode strip 32. Then, after removing the power cord 36 on the remaining epoxy heating plates, connect the connector A34 of the remaining epoxy heating plates with the connector B35 on the adjacent epoxy heating plates, align the connector 352 on the connector B35 with the connecting groove 342 on the connector A34, and then insert the connector 352 into the connecting groove 342 to complete the mutual connection between the connector A34 and the connector B35 on the two adjacent epoxy heating plates. At the same time, the two connecting ends 33 will fit in contact with each other, allowing the multiple electrode strips 32 to be interconnected and connected to the same power supply, thereby realizing the splicing and assembly between the two epoxy heating plates, and being able to power and control the heating of multiple epoxy heating plates through one power supply.

[0030] At the same time, each electrode strip 32 is provided with a pair of connecting branches 5 extending outwardly in the width direction of the electrode strip 32, and the ends of the pair of connecting branches 5 are exposed to the outside, and the ends of the connecting branches 5 of the two electrode strips 32 are respectively provided with mutually engaging clamps A34 and B35. Through the connecting branches 5, the four sides of the epoxy heating plate can be assembled and spliced, so that the user can assemble the epoxy heating plate according to the required shape and size, thereby improving the application range of the device and eliminating the need to purchase epoxy heating plates of multiple different specifications.

[0031] When the epoxy heating plate needs to be transported or stored, the user can split the larger epoxy heating plate into multiple small epoxy heating plates to make transportation and storage more convenient.

[0032] like Figure 3 As shown, a dust shielding cover 7 is also included, and the dust shielding cover 7 includes a dust shielding plate 71 clamped between a pair of clamping blocks 341 or a pair of clamping plates 351, and the dust shielding plate 71 is arranged in close contact with the connecting end 33, and an extension plate 72 is arranged on both sides of the top of the dust shielding plate 71; when the connecting end 33 is in an idle state, the end surface of the connecting end 33 can be covered by the dust shielding plate 71, thereby preventing impurities and dust from adhering to the end surface of the connecting end 33 and affecting the mutual connection between two adjacent electrode strips 32. The extension plates 72 extending on both sides of the top of the dust shielding plate 71 can limit the dust shielding plate 71 and realize the installation of the dust shielding plate 71.

[0033] Since the connection ends 33 have the same size specifications, the provision of the extension plate 72 allows the dust shielding plate 71 to be freely matched with the snap-in piece A34 or the snap-in piece B35, thereby making it easier to place the dust shielding cover 7 without distinguishing the dust shielding cover 7.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
