Description

Technical Field

[0001] This utility model belongs to the technical field of refrigeration compressor motor starting and protection devices, specifically relating to a current-type starter and protector structure with transition connection function. Background Technology

[0002] The functions of current-type starters and protectors are well-known, and further details can be found in the "Combined Structure of Current-Type Starter and Protector" recommended in Chinese patent application CN119341402A. The aforementioned CN119341402A objectively and accurately reflects the advantages in the three aspects summarized in its technical effects description.

[0003] The protector pin of the protector in the above-mentioned invention patent application is supported on the protector pin support seat and corresponds to the area above the S pin and M pin of the current starter. The protector pin locking cover of the integrated mounting mechanism structure is inserted and engaged with the protector pin support seat at the position corresponding to the upper part of the protector pin to lock the protector pin on the protector pin support seat (paragraph 0013 or 0029 of the specification).

[0004] As explained above and in conjunction with the figures disclosed in CN119341402A, the so-called combination of the current starter and protector merely defines the protector's pins. The current starter and protector remain essentially independent, unconstrained structures. This is because there is a lengthy electrical transition line between the protector pins and the protector, which does not function to integrate the current starter and protector into a relatively unified structure. Therefore, when finally applied to a refrigeration compressor and mated to its three-pin connector, an additional clamping spring is needed to firmly attach the protector to the compressor (see the second-to-last paragraph of the patent application for details). Therefore, the following technical problems exist: First, it does not achieve true structural integration and rigid connection. Specifically, since the current starter and protector are independent, the connection is loose and cannot form a reliable whole. Second, the reliability and performance of the electrical connection are relatively low because only a stable mechanical connection can guarantee the stability of the electrical contact interface. Third, the installation efficiency on the refrigeration compressor is low because the independent components lack an overall modular effect. Fourth, maintenance or replacement is relatively troublesome. Fifth, it is insufficient to reflect the compact design effect, thus affecting the utilization and layout of space. Sixth, it is not conducive to improving protection and environmental adaptability.

[0005] Given that the technical issues mentioned above are not limited to those mentioned above, it is necessary to make reasonable improvements. The technical solution to be provided below is generated in this context. Utility Model Content
