AI Technical Summary
The static contacts and moving contacts of traditional thermal protectors are prone to be inconsistently connected, resulting in the inability to conduct current and inaccurate conduction, which affects the protection effect.
The double-point staggered stacked structure thermal protector is adopted. Through the riveted connection between multiple static contact plates and movable contact plates, the metal connecting plate instantly deforms and pulls out when the current is too high, achieving rapid disconnection. The scattered distribution frame limits the movement of the movable contact plates and static contact plates to ensure stable installation.
It improves the response speed of the thermal protector during protection, avoids delays, ensures the accuracy and stability of current conduction, and enhances the protection effect of electrical equipment.

Abstract
Description
Technical Field
[0001] The utility model specifically relates to the technical field of thermal protectors, in particular to a novel double-point staggered stacked structure thermal protector. Background Art
[0002] The thermal protector is a combination of two different alloys. When current passes through it, it will generate heat. Due to the different thermal expansion coefficients of the two different alloys, the alloys are bound to bend in one direction, and the contacts will be separated, and the power will be cut off. The bending speed is proportional to the current passing through. This protects the electrical equipment.
[0003] The static contacts and moving contacts on the inside of traditional thermal protectors are often stacked up or contacted by metal connecting plates, which can easily lead to loose connections, resulting in the inability to conduct current or inaccurate conduction. To this end, we provide a new type of double-point staggered and stacked structure thermal protector, which is riveted with multiple static contacts and moving contacts. When instantaneous current passes through, it can increase the load and achieve rapid disconnection, avoiding delays in the thermal protector during protection, thereby effectively compensating for the above problems.
