[0004] Therefore, it is necessary to design a highly stable resistor that can stably support the ceramic substrate and improve the stability of resistor installation to solve the current technical problems. Summary of the invention

[0005] In view of the deficiencies in the prior art, the utility model provides a highly stable resistor which can stably support a ceramic substrate and improve the installation stability of the resistor.

[0009] The gasket ring is a rubber ring which is interference fit on the outside of the ceramic substrate.

[0010] An insulating retaining ring is sleeved on the outer side of the ceramic substrate between the upper clamp, the lower clamp and the clamp ring, one end of the insulating retaining ring abuts against the upper clamp and the lower clamp, and the other end of the insulating retaining ring abuts against the clamp ring.

[0011] The insulating baffle ring is a ceramic ring sleeved on the outside of the ceramic substrate, and the inner side of the insulating baffle ring matches the ceramic substrate.

[0012] Both ends of the mounting plate are provided with mounting holes.

[0013] The outer sides of the resistance wire and the clamp ring are both provided with high temperature resistant coatings.

The bottom of the core support plate 64 and the side support plate 65 are fixedly connected to the top of the mounting plate 53; in the present embodiment, the bracket assembly 6 is installed at the end of the ceramic substrate 1 to provide stable support for the resistor, and the mounting plate 63 of the bracket assembly 6 is used to install and fix the resistor, and the mounting plate 63 and the lower clamp 61 are connected and fixed by the side support plate 65 and the center support plate 64, which provides more stable support for the ceramic substrate 1 than the L-shaped bracket in the prior art; the bracket assembly 6 is clamped at both ends of the ceramic substrate 1 by the upper clamp 62 and the lower clamp 61, and there is no need to set a screw through the inside of the ceramic substrate 1 to fix the bracket assembly 6, and the loosening of a single bracket assembly 6 will not cause the loosening of another bracket assembly 6.

[0023] In some embodiments, a diagonal plate 66 is provided between the bottom end of the central support plate 64 and the top end of the side support plate 65.

At the same time, the gasket 8 is made of a material with a large friction coefficient, which can increase the friction force on the inner side of the clamp ring 4, the upper clamp 62, and the lower clamp 61, so that the clamp ring 4, the upper clamp 62, and the lower clamp 61 are not easy to move on the outer side of the ceramic substrate 1, thereby improving the stability of the clamp ring 4, the upper clamp 62, and the lower clamp 61.

[0025] In some embodiments, the gasket ring 8 is a rubber ring that is interference fit on the outside of the ceramic substrate 1 .

[0026] In some embodiments, an insulating retaining ring 7 is mounted on the outer side of the ceramic substrate 1 between the upper clamp 62, the lower clamp 61 and the clamp ring 4, one end of the insulating retaining ring 7 is abutted against the upper clamp 62, the lower clamp 61, and the other end of the insulating retaining ring 7 is abutted against the clamp ring 4, and the insulating retaining ring 7 forms a barrier between the clamp ring 4 and the upper clamp 62, the lower clamp 61 to prevent conduction between the clamp ring 4 and the upper clamp 62, the lower clamp 61.

[0027] In some embodiments, the insulating retaining ring 7 is a ceramic ring sleeved on the outside of the ceramic substrate 1 , and the inner side of the insulating retaining ring 7 matches the ceramic substrate 1 .
