Description

Technical Field

[0001] The utility model relates to a starting thermal protector with a stable thermal protector loading cavity, which is mainly used for starting and protecting a refrigeration compressor motor and can also be used for starting and protecting a general single-phase AC motor. Background Art

[0002] Currently, the starting thermal protector (including thermal protector and starter) used on the refrigeration compressor in the market is a combination of thermal protector and starter to form a starting thermal protector. Figure 1 The figure shows a starting thermal protector in the prior art. When the starting thermal protector is assembled, since the elastic hook 1-2 is set on the front enclosure wall 1-6, when the thermal protector 2 is loaded into the loading cavity 1-1, it is easy to cause the front enclosure wall 1-6 to be damaged. If the front enclosure wall 1-6 is damaged, the thermal protector 2 will fall off and lose the combined effectiveness with the starter 1. Utility Model Content

[0003] The utility model aims to overcome the above-mentioned deficiencies in the prior art and to provide a starting thermal protector with a reasonable structural design and a stable thermal protector loading cavity.

[0004] The technical solution adopted by the utility model to solve the above-mentioned problem is: the thermal protector loading cavity is stably started, comprising a starter and a thermal protector, the thermal protector is installed in a loading cavity formed by a surrounding wall, the loading cavity is arranged on the starter, and an elastic hook is arranged on the surrounding wall, and the elastic hook is engaged with the thermal protector, and its structural characteristics are: the front and rear sides of the surrounding wall are respectively the front surrounding wall and the rear surrounding wall, the elastic hook is arranged on the rear surrounding wall through a hook bracket, a limiting card block is arranged on the thermal protector, a limiting card slot is formed between the two limiting card blocks, and the elastic hook is located in the limiting card slot.

[0005] Furthermore, the enclosure wall is arranged in a fully enclosed or semi-enclosed structure.

[0006] Furthermore, the elastic hook is arranged in an L-shaped structure.

[0007] Furthermore, a guide surface is provided on the elastic hook.

[0008] Furthermore, when the enclosure wall is arranged in a fully enclosed structure, a grounding terminal connection plug installation groove is arranged on the enclosure wall.

[0009] Furthermore, the hook bracket is arranged on the upper part of the rear enclosure wall.

[0010] Compared with the prior art, the utility model has the following advantages: the starting thermal protector sets the elastic hook on the rear enclosure wall through the hook bracket, and is set on the upper part of the rear enclosure wall, so that the front enclosure wall can be avoided from being damaged when the thermal protector is installed, so that the thermal protector can be stably and firmly installed in the loading cavity, so that the thermal protector and the starter can be better combined with each other, and the elastic hook is designed to be a barb shape, which firmly fixes the thermal protector in the loading cavity to prevent the thermal protector from falling off.
