Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment, and in particular to a motor and a compressor. Background Art

[0002] When the air conditioner is in operation, it needs to use the compression of gas to assist in the exchange of heat. The compression of the gas is achieved by driving the compressor through a motor. The motor is connected to the external circuit through leads, and the leads are fixedly arranged through lead boxes and other lead wire components.

[0003] In the prior art, multiple crimping terminals are provided in the motor, and each crimping terminal needs to be connected to a corresponding lead wire. To ensure insulation, two adjacent crimping terminals need to be kept at a certain distance, so as to ensure that the creepage distance meets the insulation requirements, so as to avoid the situation where the crimping terminals discharge each other due to high current or large pulse state during the operation of the motor.

[0004] However, when the dimensional error is large during the production process, it may cause the distance between the two crimping terminals to be smaller than the insulation spacing, resulting in reduced insulation withstand voltage and pulse resistance of the motor as a whole, and thus reduced reliability of the motor. Summary of the invention

[0005] The purpose of the present invention is to provide a motor and a compressor, which solves the problem that when insulation is achieved only by maintaining a spacing in the prior art, when there is a large dimensional error in the production process, it is easy to cause the spacing between the two crimping terminals to be smaller than the insulation spacing, resulting in reduced reliability of the motor as a whole.

[0035] Embodiments of the present invention provide a motor and a compressor.

[0036] Reference Figure 1 and Figure 2 The motor includes a terminal support 1 and a plurality of separators 2. The terminal support 1 has a terminal base 11, and the terminal base 11 has a plug-in cavity and a plug-in interface 111 located at the top of the plug-in cavity; a plurality of separators 2 are arranged in the plug-in cavity, and a terminal cavity 112 for arranging a crimping terminal is formed between two adjacent separators 2, and the separators 2 are higher than the plug-in interface 111 or the top of the crimping terminal.

[0037] Specifically, the terminal support 1 is made of insulating material and is annular in shape, and the terminal seat 11 is in the shape of an elongated shell, which can be fixed to the outer peripheral wall of the terminal support 1 by welding or bonding. The upper end opening of the terminal seat 11 serves as a plug-in port 111. The separator 2 is vertically arranged in the plug-in cavity, and a plurality of separators 2 are spaced apart along the length direction of the terminal seat 11. In this embodiment, two separators 2 are arranged at equal intervals to form three terminal cavities 112 in the plug-in cavity, and a crimping terminal is correspondingly arranged in each of the three terminal cavities 112, which respectively correspond to the three-phase outlet terminals U, V, and W. The width of the separator 2 can be designed according to the size of the actual plug-in cavity. Without increasing the thickness of the separator 2, the height of the separator 2 is increased so that the separator 2 extends out of the plug-in port 111 and is higher than the side wall of the terminal seat 11, so as to increase the creepage distance between the terminals of different phases.

[0038] A separated terminal cavity 112 is formed in the plug-in cavity by the separator 2, and a plurality of crimping terminals can be directly fixed in the corresponding terminal cavity 112. The two adjacent crimping terminals are isolated by the separator 2, and the separator 2 is higher than the plug-in interface 111 or the top of the crimping terminal, so that the separator 2 is higher than the end face of the terminal seat 11, so that the creepage distance between the two adjacent crimping terminals can be increased while keeping the thickness of the separator 2 unchanged, thereby effectively improving the insulation withstand voltage and pulse resistance of the motor as a whole, so as to enhance the operating reliability of the motor.

[0039] In some embodiments of the present invention, the partition 2 includes a partition plate 21 and an extension plate 22. One side of the partition plate 21 is fixed in the plug-in cavity, and the other side extends toward the plug-in port 111; the extension plate 22 is disposed on a side of the partition plate 21 close to the plug-in port 111, and the thickness of the extension plate 22 is less than the thickness of the partition plate 21. The side of the extension plate 22 away from the partition plate 21 extends out of the plug-in port 111. The length of the extension plate 22 extending out of the plug-in port 111 is between 1.3 mm and 1.5 mm.

[0040] Specifically, the partition plate 21 is located in the plug-in cavity, and it can be integrally formed with the terminal seat 11, or fixedly connected by welding or bonding, etc., which is not limited by the present invention. The lower side of the partition plate 21 is fixedly connected to the bottom wall of the plug-in cavity, and the upper side is close to the plug-in port 111. The extension plate 22 is fixed on the upper side of the partition plate 21, and the extension plate 22 is integrally formed with the partition plate 21 to facilitate production and processing. The distance that the extension plate 22 extends out of the plug-in port 111 is limited to between 1.3 mm and 1.5 mm, which can ensure that the creepage distance is effectively increased, and also enable the terminal seat 11 to be plugged in with the lead wire assembly 3 of the motor.

[0041] By providing a partition plate 21 and an extension plate 22, two adjacent crimping terminals are effectively separated, and the design of the extension plate 22 enables the partition 2 to smoothly extend out of the plug-in port 111, thereby increasing the creepage distance between two adjacent out-of-phase crimping terminals, effectively ensuring the insulation withstand voltage and pulse resistance of the motor as a whole.

[0042] Reference Figure 3 In some embodiments of the present invention, the motor further comprises a lead wire assembly 3. The lead wire assembly 3 is plug-fitted with the terminal seat 11, and the lead wire assembly 3 has a separation groove 31 plug-fitted with the extension plate 22.

[0043] Specifically, the lead wire assembly 3 includes a lead shell 32. The lead shell 32 has a connecting cavity 321 for the terminal seat 11 to be inserted, and the connecting cavity 321 has a plug-in terminal 33 that corresponds to the crimping terminal one by one and is plugged in, and the crimping terminal is in the shape of a vertically arranged plate. The separation groove 31 is located between two adjacent plug-in terminals 33, and is arranged one by one with the partition 2. The depth of the separation groove 31 is between 1.3 mm and 1.5 mm, and its specific depth can be designed according to the length of the extension plate 22 extending out of the plug interface 111. The size of the extension plate 22 can be consistent with the size of the separation groove 31, that is, the width and length of the extension plate 22 can be equal to the width and length of the separation groove 31, and the side of the extension plate 22 inserted into the separation groove 31 has a chamfer.

[0044] By setting the separation groove 31 at the corresponding position of the lead-out shell 32, when the lead-out shell 32 is plugged into the terminal seat 11, the crimping terminal is plugged into the plug-in terminal 33, and the extension plate 22 of the partition 2 will be inserted into the separation groove 31, and the side of the extension plate 22 extending out of the plug-in port 111 can be fully inserted into the separation groove 31, so that after the lead-out shell 32 is installed, a large creepage distance can be maintained between the out-of-phase terminals, thereby further improving the insulation withstand voltage and pulse resistance of the motor. The chamfered design of the extension plate 22 reduces the cross-sectional area of ​​the side where the extension plate 22 is inserted into the separation groove 31, which facilitates the smooth insertion of the extension plate 22 into the separation groove 31.

[0045] The compressor includes: a motor as in any of the above embodiments.

[0046] The compressor can be used in electrical equipment such as air conditioners. When in use, the motor drives the compressor to compress the air. During operation, the motor can maintain good insulation, voltage resistance and pulse resistance, which is beneficial to making the overall operation reliability of electrical equipment such as air conditioners higher, so as to smoothly meet the user's usage needs.
