Description

Technical Field

[0001] This utility model relates to the field of temperature protector technology, specifically a silver dot bimetallic strip assembly for a temperature protector. Background Technology

[0002] A temperature protector is an automatic control element that, based on changes in the ambient temperature, undergoes internal physical deformation to produce specific effects, resulting in either a switching action (turning on or off). It has a wide range of applications, used in numerous products such as home appliances, motors, and refrigeration / heating systems, depending on the type of temperature controller. The core component of a temperature protector is its contacts, and the material of these contacts has a significant impact on their load current, contact resistance, and lifespan. Silver contacts, made of silver, are the points of separation and contact during the opening and closing of electronic devices. Silver contacts offer several advantages: 1. Excellent conductivity: Silver has excellent electrical conductivity, allowing it to conduct current normally even at low temperatures. Good contact and conductivity are among the main advantages of silver contacts. 2. Strong oxidation resistance: Silver contacts are not easily oxidized or deteriorated during prolonged use, maintaining stable performance. Compared to contacts made of other materials, silver contacts have a longer service life. 3. Good wear resistance: Silver contacts have high hardness and wear resistance, preventing wear and tear during long-term use.

[0003] However, existing silver points and bimetallic strips can affect the conductivity of the temperature protector when subjected to unstable vibrations after installation. Furthermore, the related component structure requires multiple parts for separate assembly, occupying a large space, and loose connections can easily affect overall performance, leading to poor circuit contact or open circuits. In addition, manual adjustment of the silver points is required, which is a cumbersome process. Therefore, it is necessary to propose a modular, automatically adjustable silver point and bimetallic strip assembly for temperature protectors to overcome these problems. Utility Model Content

[0004] To address the aforementioned shortcomings in the existing technology, the purpose of this utility model is to provide a silver point bimetallic strip assembly for a temperature protector. This assembly solves the problems of existing silver contacts affecting conductivity when unstable shaking occurs after installation, the fragmented and space-consuming assembly process, the potential impact on overall performance when connections become loose, leading to poor circuit contact or open circuits, and the cumbersome process requiring corresponding manual adjustments.
