Description

Technical Field

[0001] The invention relates to the field of manufacturing ceramic PTC heating elements, in particular to a corrugated ceramic PTC metal mounting bracket structure. Background Art

[0002] PTC heater is PTC heater, PTC is the English abbreviation and the full name is: Positive Temperature Coefficient. Because PTC heater has the characteristics of fast startup speed, good temperature control, ideal working reliability, energy saving and long service life, it is widely used as an electric heating element for manufacturing various electric heating appliances such as air conditioners, heaters, dryers, dishwashers, water heaters, food processors, heated floor cleaning machines, etc., and even as an important component of control and protection devices such as current limiters, filter protectors, overload protectors, demagnetization controllers, and start controllers. At present, the ceramic PTC mounting bracket, the traditional mounting bracket is made of heat-resistant plastic material, and different product designs and molds are different mounting brackets. This method has a long new product development cycle and a high bracket cost. Summary of the invention

[0003] In order to solve the above problems, the present invention proposes a corrugated ceramic PTC metal mounting bracket structure.

[0004] A corrugated ceramic PTC metal mounting bracket structure includes a bent metal sheet metal part fixed to the ceramic PTC by side screws, an insulating gasket arranged on the bent metal sheet metal part for secondary insulation, and a mounting bracket bent sheet metal part arranged at the middle position of the bent metal sheet metal part, wherein one end of the mounting bracket bent sheet metal part away from the bent metal sheet metal part is pressed on the ceramic PTC.

[0005] The bent metal sheet metal part is matched with the bent metal sheet metal part of the mounting bracket through a middle screw.

[0006] The bent metal sheet metal parts and the bent metal sheet metal parts of the mounting bracket are both made of galvanized sheet metal or stainless steel.

[0007] The bent metal sheet is provided with a turning hole capable of increasing the stress-bearing length of the thread.

[0008] The beneficial effects of the present invention are as follows: the present invention fixes by bending metal sheet metal parts, thereby avoiding the mold opening cycle of plastic parts, effectively reducing the product development cycle, and the price is cheaper than plastic parts, and at the same time does not affect the final product quality of the product. The bent sheet metal parts of the middle reinforcement mounting bracket effectively avoid matching tolerances and prevent the fixing screws on both sides from tearing the ceramic PTC; the present invention is easy to manufacture, easy to modify, cheap, and has broad market prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0010] Figure 1 It is a schematic diagram of the three-dimensional structure of the present invention;

[0011] Figure 2 It is a schematic diagram of the local three-dimensional structure of the present invention. DETAILED DESCRIPTION

[0012] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below.

[0013] like Figure 1 and Figure 2 As shown, a corrugated ceramic PTC metal mounting bracket structure includes a bent metal sheet metal 1 fixed on the ceramic PTC by side screws 5, an insulating gasket 2 arranged on the bent metal sheet metal 1 for secondary insulation, and a mounting bracket bent sheet metal 3 arranged at the middle position of the bent metal sheet metal 1 for reinforcement, and the end of the mounting bracket bent sheet metal 3 away from the bent metal sheet metal 1 is pressed on the ceramic PTC.

[0014] The insulating washers 2 are provided in two groups.

[0015] The present invention fixes the metal sheet metal part 1 by bending, thereby avoiding the mold opening cycle of the plastic part, effectively reducing the product development cycle, and the price is cheaper than that of the plastic part, and at the same time does not affect the final product quality of the product.

[0016] The bent metal sheet metal part 1 is matched with the bent metal sheet metal part 3 of the mounting bracket through the middle screw 4.

[0017] The bent metal sheet metal part 1 and the mounting bracket bent metal sheet metal part 3 are both made of galvanized sheet metal or stainless steel.

[0018] The bent sheet metal part 3 of the middle reinforcement mounting bracket effectively avoids the matching tolerance and prevents the fixing screws on both sides from tearing the ceramic PTC. The invention is easy to manufacture, easy to modify, cheap and has broad market prospects.

[0019] The bent metal sheet 1 is provided with a turned hole 6 which can increase the stress-bearing length of the thread, and the middle screw 4 cooperates with the turned hole 6 .

[0020] The bent sheet metal part 3 of the mounting bracket is L-shaped, and an arc is provided at the corner.

[0021] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
