Description

Technical Field

[0001] This utility model belongs to the field of resistor technology, specifically relating to a stainless steel resistor with a fixed edge. Background Technology

[0002] In the prior art, Chinese utility model patent document with authorization announcement number CN213211846U discloses a stainless steel resistor with a central slot and upper and lower edge fixing. The resistor sheet has U-shaped mica paper at both ends. The opening end of the upper slot of the resistor sheet is located in the top U-shaped mica paper, and the opening end of the lower slot is located in the bottom mica paper. The U-shaped fixing plate fixes the U-shaped mica paper. This structure can prevent the resistor sheet from shaking.

[0003] However, in the aforementioned prior art, mica paper itself is brittle and has a low coefficient of friction. When installing the U-shaped fixing plate, it is easy to scratch the mica paper, causing insulation failure and short circuit. Furthermore, due to the low coefficient of friction of mica paper, the frictional resistance between the U-shaped fixing plate and the mica paper, and between the mica paper and the resistor sheet is small. Moreover, the U-shaped fixing plate lacks other support structures, which makes it easy for the U-shaped fixing plate to slip off the resistor sheet, affecting the support effect and potentially causing short circuits between the resistor sheets.

[0004] Therefore, there is a need to design a stainless steel resistor with an edge-sealed fixing that can prevent insulation failure during installation and provide stable support for the upper and lower ends of the resistor element, preventing slippage, in order to solve the current technical problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the present invention provides a stainless steel resistor with edge-sealed fixing that can avoid insulation failure during installation and provide stable support for the upper and lower ends of the resistor element, making it less prone to slippage.

[0006] The technical solution of this utility model is as follows: a stainless steel resistor with edge fixing includes two symmetrical support plates. Several resistance plates are mounted between the two support plates through a connecting rod. U-shaped mica paper is fitted on the outer sides of both the upper and lower ends of the resistance plates. Two clamping plate assemblies are provided on both sides of the U-shaped mica paper to clamp and fix the ends of the resistance plates. A support beam is detachably fixedly assembled on the side of the clamping plate assembly away from the resistance plates. The two ends of the support beam are detachably fixedly assembled and connected to the two support plates respectively.

[0007] Furthermore, the clamping plate assembly has a clamping strip, and a support strip is vertically fixed on the top side of the clamping strip opposite to the U-shaped mica paper. A second stud corresponding to the support beam is provided on the top of the support strip. The support beam has a support beam body, and a second oblong hole matching the second stud is opened on the support beam body. A second washer nut for detachably fixing the second stud to the support beam body is fitted on the second stud.

[0008] Furthermore, a connecting plate is vertically fixed at both ends of the support beam body on the side away from the resistor sheet. A first waist-shaped hole is provided on the connecting plate. A first stud corresponding to the first waist-shaped hole is provided on one side of the bracket plate. A first washer nut for detachably fixing the first stud to the connecting plate is mounted on the first stud.

[0009] Furthermore, reinforcing plates are vertically arranged on both sides of the side of the support beam body facing away from the resistor sheet, and the two ends of the reinforcing plates are vertically fixedly connected to the corresponding connecting plates.

[0010] Furthermore, the length of the long side of the clamping strip is 3-8 cm shorter than the length of the long side of the U-shaped mica paper; the length of the wide side of the clamping strip is 1-3 cm shorter than the length of the wide side of the U-shaped mica paper.

[0011] Furthermore, a buffer film is fixedly provided on the side of the clamping strip near the U-shaped mica paper.

[0012] Furthermore, the buffer film is a rubber film adhered to the clamping strip, and the thickness of the buffer film is 0.5~1mm.

[0013] The beneficial effects of this utility model are:

[0014] (1) In this utility model, both sides of the upper and lower ends of the resistor sheet are clamped and fixed by the clamping plate assembly. At the same time, a support beam is provided on the side away from the resistor sheet to support the clamping plate assembly and the end of the resistor sheet, which can prevent the resistor sheet from shaking. Meanwhile, the resistor sheet is not easy to slip out of the clamping plate assembly, thus ensuring its stability.

[0015] (2) After the clamping plate assembly is clamped on both sides of the U-shaped mica paper, it is assembled on the support beam for fixation. Compared with the set connection method in the prior art, it avoids scratching the mica paper and causing insulation failure and short circuit. Attached Figure Description
