Description

Technical Field

[0001] This utility model relates to the field of temperature controller protection and technology, specifically a high-temperature resistant and anti-slip temperature controller sleeve. Background Technology

[0002] Thermostats are widely used in electrical equipment (such as motors, heaters, etc.). Their sheaths are mainly used to protect internal sensitive components from high temperatures and external contamination. Traditional sheaths are mostly made of heat-shrinkable materials, which are fixed by heat shrinking to prevent movement. However, the high temperature resistance of these materials is limited. They can usually only pass the 600℃ glow wire test and cannot meet the requirements of higher safety standards (such as 850℃).

[0003] Using high-temperature resistant materials (such as polyetheretherketone (PEEK), polyimide (PIT), or ceramic fiber reinforced composites) can improve temperature resistance, but these materials typically lack heat shrinkage properties, which can cause the sheath to shift (move) during long-term use, affecting the stability of the temperature controller. Furthermore, conductive contaminants such as carbon powder can easily enter the open end of the sheath, potentially causing micro-short circuits, arcing, and ultimately motor failure.

[0004] In existing technologies, ultrasonic welding is mainly used for joining plastic parts, but its application in sealing and fixing thermostat sheaths, especially in innovative applications for preventing movement and sealing high-temperature sheaths, has not yet been seen. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature resistant and anti-slip temperature controller sleeve to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant and anti-slip thermostat sheath, comprising a wire, one end of which is provided with a thermostat, and an insulating sheath is provided on the outside of the thermostat, the insulating sheath being tubular and fitted onto the outside of the thermostat.

[0007] Further optimized, the insulating sheath is made of a high-temperature resistant polymer, such as PEEK, PIT, or a composite material containing glass fiber / ceramic filler.

[0008] As a further optimization, welding areas are reserved at both ends of the insulating sheath.

[0009] Further optimized, the inner wall of the insulating sheath is provided with a raised rib structure or a wear-resistant texture structure.

[0010] In a further optimized configuration, the insulating sheath is connected to the temperature controller via ultrasonic welding. Beneficial effects

[0011] The high-temperature resistant and anti-slip temperature controller sleeve provided by this utility model is welded and fixed to the temperature controller housing to avoid axial displacement. The seal is completely closed to prevent charged contaminants such as carbon powder from entering. By combining material optimization and ultrasonic welding, the contradiction between high temperature resistance, anti-slip, and sealing is resolved. Attached Figure Description

[0012] Figure 1 This is a cross-sectional view of the overall structure of this utility model. Detailed Implementation

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Example

[0014] like Figure 1 As shown, a high-temperature resistant and anti-slip temperature controller sheath includes a wire 1, a temperature controller 2 at one end of the wire 1, and an insulating sheath 3 on the outside of the temperature controller 2. The insulating sheath 3 is tubular and fitted onto the outside of the temperature controller 2.

[0015] In this embodiment, the insulating sheath 3 is a high-temperature resistant polymer, such as PEEK, PIT, or a composite material containing glass fiber / ceramic filler.

[0016] Welding areas are reserved at both ends of the insulating sheath 3.

[0017] The inner wall of the insulating sheath 3 is provided with a raised rib structure or a wear-resistant texture structure.

[0018] The insulating sleeve 3 is welded to the temperature controller 2 by ultrasonic welding.

[0019] Use high-temperature resistant polymers (such as PEEK, PIT, or composites containing glass fiber / ceramic fillers) to ensure passing the 850°C glow wire test.

[0020] The sheath is tubular with pre-reserved welding areas at both ends. The inner wall can be provided with ribs or textures to enhance friction with the thermostat.

[0021] Ultrasonic vibration is applied to both ends of the sheath to locally melt and press the material together, forming a permanent seal.

[0022] Weld the sheath to the thermostat housing to prevent axial displacement.

[0023] The seal is completely closed, preventing charged contaminants such as toner from entering.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
