Problems solved by technology
[0003] Existing miniature overcurrent / overheating protectors are bulky, relatively primitive in technology and low in efficiency, and their structure is suitable for manual manufacturing, resulting in inconsistent quality characteristics. Poor welding problems, etc.; on the other hand, labor costs remain high, and factory costs are difficult to reduce
These problems have always been the bottleneck of the entire industry; secondly, imported equipment from abroad is expensive

The invention discloses a small-volume heat protector which comprises a base, a first wiring terminal, a static contact piece and a temperature sensing piece, wherein the first wiring terminal is electrically connected with the static contact piece; the first wiring terminal, the second wiring terminal and the static contact piece are arranged in the base; one end of the first wiring terminal, one end of the second wiring terminal and one end of the static contact piece are arranged in the base respectively, and the other ends of the first wiring terminal, the second wiring terminal and the static contact piece extend to the outer side of the base; the temperature sensing piece is arranged at the upper part of the temperature sensing piece; one end of the temperature sensing piece is fixed at the upper part of the base, and the other end of the temperature sensing piece is connected with the upper part of the far end of the static contact piece; a fixing piece is arranged above the far end of the temperature sensing piece; two rivets are arranged at one end of the fixing piece to fix the fixing piece with the static contact piece, a bulge is arranged on the lower end surface of the other end of the fixing piece, and the bottom of the bulge is connected with the upper end surface of the temperature sensing piece. The heat protector is simple in structure and convenient to assemble, and the product qualification rate can be increased.
Description
technical field [0001] The invention relates to the technical field of automatic production of electrical protectors, in particular to a small-volume thermal protector. Background technique [0002] Miniature overcurrent / overheat protectors are widely used in the fields of overheat / overcurrent protection for various types of motors, PCB circuit boards, electric heating products, batteries, etc. [0003] Existing miniature overcurrent / overheating protectors are bulky, relatively primitive in technology and low in efficiency, and their structure is suitable for manual manufacturing, resulting in inconsistent quality characteristics. Poor welding problems, etc.; on the other hand, labor costs remain high, making it difficult to reduce factory costs. These problems have always been the bottleneck of the entire industry; secondly, imported equipment from abroad is expensive. Contents of the invention [0004] The purpose of the present invention is to provide a thermal protec...
