Technical Field

[0001] The utility model relates to a thermal protector mounting bracket, belongs to the field of thermal protectors, and is mainly used for fixing and mounting over-temperature rise and over-current thermal protectors of refrigeration compressors or other motors. Background Art

[0002] At present, all refrigeration compressors are equipped with a thermal protector, which is mainly used for over-temperature and over-current protection of refrigeration compressors. There are several installation methods in the prior art, such as Figure 1 The schematic diagram of the installation of the thermal protector 5 on the refrigeration compressor 7 is shown in the figure. When installing the thermal protector 5, the connecting pin 5-1 of the thermal protector 5 must be inserted into the three-core terminal C end 6-1 of the three-core terminal 6, and then the thermal protector 5 is positioned with the help of a spring clamp; Figure 2 The schematic diagram of the installation of the thermal protector 5 on the refrigeration compressor 7 is shown. When installing the thermal protector 5, the thermal protector 5 needs to be first installed into the thermal protector installation bracket, and then the three-core terminal 6 is inserted.

[0003] In view of this, a thermal protector positioning device and a thermal protector are disclosed in the patent document with application number 201922469498.7. The first installation method in the above-mentioned prior art is inconvenient to install due to its existence, and requires two manual installation processes, which increases the labor cost; although the second installation method is much more convenient, in these two installation methods, the thermal protector is installed directly above the three-core terminal on the compressor housing, which increases the height of the plastic cover and limits the space for lowering the height of the compressor housing. Figure 3 As shown, the thermal protector mounting bracket of the prior art is installed vertically, that is, α is 90°, so that L is increased to 11 mm. Utility Model Content

[0004] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a thermal protector mounting bracket with a reasonable structural design.

[0005] The technical solution adopted by the utility model to solve the above-mentioned problem is: the thermal protector mounting bracket comprises a thermal protector positioning ring, a thermal protector positioning cavity, a connecting pin loading cavity and a connecting pin loading seat, the connecting pin loading seat is fixed to the outer wall of the thermal protector positioning ring, the thermal protector positioning ring is provided with a thermal protector positioning cavity, the connecting pin loading seat is provided with a connecting pin loading cavity, the thermal protector positioning cavity is communicated with the connecting pin loading cavity, the thermal protector positioning ring is provided with an elastic claw and a limiting boss, and its structural characteristics are: the connecting pin loading seat is inclined, a positioning card plate is provided on the connecting pin loading seat, a positioning card pin is provided on the positioning card plate, a positioning card groove is formed between the positioning card pin and the positioning card plate, and a guide angle is provided on the positioning card pin.

[0006] Furthermore, the angle between the connecting pin loading seat and the horizontal plane is α, and the value range of α is 30°-50°, and preferably α is 40°.

[0007] Furthermore, the thermal protector mounting bracket is used to mount the thermal protector, and the thermal protector is connected to the three-core terminal C end of the three-core terminal via a connecting pin.

[0008] Furthermore, the connecting pins are located in the connecting pin loading cavity.

[0009] Furthermore, the distance between the center of the thermal protector and the C end of the three-core terminal is L, and the value range of L is 4-6 mm, and preferably L is 5 mm.

[0010] Compared with the prior art, the utility model has the following advantages: a plurality of elastic claws and limiting bosses are arranged in the thermal protector positioning ring of the thermal protector mounting bracket, so that the thermal protector and the thermal protector positioning ring can be fixed firmly and stably; by tilting the connecting pin loading seat, the height of L can be reduced, so as to reduce the installation space of the thermal protector, reduce the volume of the plastic outer cover on the compressor shell, and reduce the height size of the compressor, so as to meet the needs of the miniaturization design development of the compressor; by setting the guide angle, when the positioning pin contacts with the M end and the S end of the three-core terminal, a guiding role can be played.

The change or adjustment of their relative relationship, without substantially changing the technical content, should also be regarded as the scope of the implementation of the utility model.

[0026] The thermal protector mounting bracket in this embodiment includes a thermal protector positioning ring 1, a thermal protector positioning cavity 2, a connecting pin loading cavity 3 and a connecting pin loading seat 4. The connecting pin loading seat 4 is fixed to the outer wall of the thermal protector positioning ring 1.

[0027] The connecting pin loading seat 4 in this embodiment is tilted, that is, the angle between the connecting pin loading seat 4 and the horizontal plane is α, that is, the angle between the line connecting the three-core terminal M end 6-2 and the three-core terminal S end 6-3 in the three-core terminal 6 and the line connecting the center of the thermal protector 5 and the three-core terminal C end 6-1 is α, and the value range of α is 30°-50°, preferably α is 40°, and a positioning card plate 1-4 is provided on the connecting pin loading seat 4, and a positioning card foot 1-3 is provided on the positioning card plate 1-4, a positioning card groove 1-5 is formed between the positioning card foot 1-3 and the positioning card plate 1-4, and a guide angle 1-6 is provided on the positioning card foot 1-3.

[0028] In this embodiment, the thermal protector mounting bracket is used to install the thermal protector 5, and the thermal protector 5 is connected to the three-core terminal C end 6-1 of the three-core terminal 6 through the connecting pin 5-1. The connecting pin 5-1 is located in the connecting pin loading cavity 3. The distance between the center of the thermal protector 5 and the three-core terminal C end 6-1 is L, and the value range of L is 4-6mm, and preferably L is 5mm.

[0029] Specifically, a plurality of elastic claws 1-1 and a plurality of limiting bosses 1-2 are provided on the inner side of the positioning ring 1. The thermal protector 5 is clamped and fixed in the thermal protector positioning cavity 2 through the plurality of elastic claws 1-1 to prevent it from falling off. The plurality of limiting bosses 1-2 prevent the thermal protector 5 from shifting or shaking in the thermal protector positioning cavity 2. The two positioning pins 1-3 can fix the entire thermal protector mounting bracket on the three-core terminal M end 6-2 and the three-core terminal S end 6-3 of the three-core terminal 6 on the outside of the refrigeration compressor 7.

[0032] like Figure 3 , Figure 6As shown, the vertical design installation has a height distance more than twice that of the 40° angle design installation. Therefore, the improved 40° angle design installation can reduce the space for the installation height of the thermal protector and reduce the height size of the compressor, thereby meeting the needs of the miniaturization design development of the compressor.
