[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0024] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0025] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0026] Compressor protectors are essential for maintaining normal operating voltages in industrial equipment. During operation, a compressor protector typically monitors the temperature of the motor windings in real time to control the compressor's operation and shutdown at high temperatures, preventing carbon deposits, stalls, and other issues that could damage the compressor due to excessive temperatures. As commercial compressors continue to become smaller, their reliability and protection measures are improving. Existing protectors are typically either external or internal.

[0027] When installing an external protector, additional installation space is required, and the installation process is relatively complicated, which increases installation cost and time. In addition, the external protector may cause poor wiring due to vibration, looseness, etc., affecting the protection effect.

[0028] The installation structure of the built-in thermal protector is to tie the protector directly to the compressor motor outlet. The compressor motor outlet is generally in a tight position, and the tying method and strength are different. The protector is prone to fall off and collision due to vibration and collision during transportation and transshipment of the compressor.

[0029] The utility model provides a new compressor built-in protector structure, such as Figures 1 to 3 As shown, it includes a protector body 1 and a mounting frame 2. The mounting frame 2 includes a mounting portion 21 and a fixing portion 22. The mounting portion 21 is provided with a fixing groove 211. The protector body 1 is engaged with the fixing groove 211, and the fixing portion 22 is plugged into the motor fixing frame in the compressor.

[0030] In this embodiment, the protector body 1 is firmly embedded in the fixing groove 211 and is fixed to the compressor motor output terminal through the fixing part 22, which can ensure the stability of the protector body 1 when it is built into the compressor, prevent the protector from loosening and falling off during the operation of the compressor, and reduce the inconsistency of the position, method, and strength of the fixation caused by manual binding, thereby improving the reliability of the motor and effectively improving the installation efficiency of the built-in compressor of the protector body 1.

[0031] In this embodiment, the mounting portion 21 includes a base plate 212 and a side panel 213. The side panel 213 is semi-enclosed by the outer wall of the protector body 1. A first limiting member 214 corresponding to the side panel 213 is provided on the base plate 212. A second limiting member 215 corresponding to the base plate 212 is provided on the top of the side panel 213. The fixing groove 211 is formed in the accommodating space formed by the joint action of the base plate 212, the side panel 213, the first limiting member 214 and the second limiting member 215.

[0032] In this embodiment, the bottom plate 212 is the basic part of the mounting portion 21, which provides a stable support surface for the protector body 1 for installation and contact with the bottom of the protector body 1; the side panel 213 semi-surrounds the outer wall of the protector body 1, and plays a role in positioning and limiting the movement of the protector body 1; the first limit member 214 is used to limit the movement of the protector body 1 in the horizontal direction; the second limit member 215 is used to limit the movement of the protector body 1 in the vertical direction; the bottom plate 212, the side panel 213, the first limit member 214, and the second limit member 215 work together to form a complete limiting system, ensuring the stable installation of the protector body 1 in three-dimensional space.

[0033] In other embodiments, the inner wall of the side panel 213 may be provided with cushioning cotton, rubber pads, etc., so that the side panel 213 fits tightly against the outer wall of the protector body 1, which can reduce vibration and noise and improve the stability of the installation. At the same time, the arc structure can enable the protector body 1 to better cooperate and install with the mounting frame 2, and can effectively reduce friction and resistance, thereby improving the smoothness and reliability of the installation.

[0034] In this embodiment, both the first and second limiting members 214, 215 are raised structures. In this embodiment, horizontally, the protector body 1 abuts between the first limiting member 214 and the side panels 213. When the protector body 1 is placed on the bottom plate 212, its sidewalls tightly abut between the first limiting member 214 and the side panels 213. This not only limits the horizontal movement of the protector body 1 but also ensures a reasonable gap between it and the side panels 213, thus preventing damage caused by vibration or impact. Vertically, the second limiting member 215 forms a certain vertical distance from the bottom plate 212. The protector body 1 abuts between the bottom plate 212 and the second limiting member 215. When the protector body 1 is fully embedded in the fixing slot 211, its upper and lower ends tightly abut between the bottom plate 212 and the second limiting member 215, effectively limiting the vertical movement of the protector body 1 and ensuring its stability and reliability after installation.

[0035] It should be noted that, in this embodiment, the shape and size of the accommodating space match those of the protector body 1 , so that the protector body 1 can be tightly embedded therein.

[0036] In this embodiment, the side panel 213 includes a connecting section 2131 and an expansion section 2132. The connecting section 2131 is fixedly connected to the base plate 212. The length and width of the expansion section 2132 are respectively greater than those of the connecting section 2131, resulting in a stepped structure for the side panel 213. In this embodiment, the connecting section 2131 is the portion that securely connects the side panel 213 to the base plate 212. The expansion section 2132 extends outward from the connecting section 2131, resulting in a stepped structure for the side panel 213. This provides a larger support area for the protector body 1, allowing the side panel 213 to better fit within the protector body 1. This also increases the overall strength and stability of the side panel 213, helping to reduce vibration and noise.

[0037] In this embodiment, the front and rear ends of the side panel 213 are both configured as arc-shaped structures, which can better disperse stress when subjected to external forces, thereby improving the overall structural strength of the side panel 213 and helping to reduce the risk of damage to the side panel 213 due to stress concentration.

[0038] In this embodiment, the connection between the expansion section 2132 and the connection section 2131 is set as a chamfered structure. The chamfered structure can play a guiding and protective role. When the protector body 1 is installed or disassembled, it can pass through this place more easily, which can effectively reduce the friction and resistance during the installation process. The chamfered structure can effectively improve the fatigue resistance of the side panel 213, reduce stress concentration, and provide better support and protection for the protector body 1.

[0039] In this embodiment, the mounting portion 21 is configured as a symmetrical structure along its horizontal central axis, which can effectively improve the stability and reliability of the installation. Moreover, due to the symmetry of the structure, the mounting portion 21 can distribute stress more evenly when subjected to force, thereby reducing the risk of damage caused by stress concentration.

[0040] In this embodiment, the fixing portion 22 is located on the bottom end surface of the mounting portion 21. The fixing portion 22 includes a fixing section 221 and an insertion section 222. The fixing section 221 is wider than the insertion section 222 to enhance the overall load-bearing capacity. The insertion section 222 is inserted into the motor mounting bracket within the compressor. It should be noted that the motor mounting bracket within the compressor must be provided with a matching groove for the insertion section 222 to prevent the protector body 1 from moving or falling off after installation.

[0041] In this embodiment, the mounting frame 2 is configured as an integrally formed structure, which can effectively improve the strength and stability of the mounting frame 2. Since the mounting frame 2 is an integral component, no additional connectors or fasteners are required to fix the various parts, thereby reducing the installation cost and complexity and simplifying the manufacturing and installation process.

[0042] In this embodiment, the protector body 1 includes an electrical connection terminal 11, which is located on the side of the protector body 1 facing the first limit member 214, ensuring that when the protector body 1 is installed in the fixing groove 211, the electrical connection terminal 11 can be conveniently connected to the corresponding terminal of the compressor. At the same time, the height of the first limit member 214 is lower than the height of the electrical connection terminal 11, avoiding interference of the first limit member 214 with the connection of the electrical connection terminal 11, thereby ensuring the reliability and stability of the connection.

[0043] In this embodiment, the power terminals 11 include two groups, and the two groups of power terminals 11 are symmetrically distributed on both sides of the horizontal axis of the protector body 1, which not only improves the connection flexibility but also ensures the balance of the electrical performance of the two groups of power terminals 11.

[0044] In this embodiment, one set of power terminals 11 is electrically connected to the common terminal terminals of the compressor, so that the compressor can receive a stable power input from the motor and thus operate normally. The other set of power terminals 11 is electrically connected to two circuits, and the two circuits are respectively electrically connected to the starting winding terminal terminals and the running winding terminal terminals of the compressor, ensuring that the compressor can obtain appropriate current supply during the startup and operation stages, thereby ensuring its performance and reliability.

[0045] It should be noted that the protector body 1 is a prior art, and those skilled in the art should be aware of its structure, principle, and usage, etc., which will not be described in detail here.

[0046] In this embodiment, the horizontal central axes of the protector body 1 and the mounting frame 2 coincide with each other, that is, the two are aligned in the horizontal direction, which can ensure a close fit between the two in physical structure, improve the overall stability and reliability, and at the same time, help reduce vibration and noise caused by improper installation or deviation.

[0047] The utility model provides a novel compressor built-in protector structure. During installation, the protector body 1 is embedded in the fixing groove 211 of the installation part 21 to ensure that it is tightly fitted with the first limit piece 214, the second limit piece 215, and the side panel 213. Then, the fixing part 22 is inserted into the motor fixing frame in the compressor, and the insertion section 222 is used to cooperate with the fitting groove to achieve fixation. Finally, the power terminal 11 is connected to the corresponding terminal of the compressor as needed to complete the electrical connection. During operation, when the compressor starts, the motor supplies power to the protector body 1 through the common terminal, and the protector body 1 supplies power to the starting winding terminal and the running winding terminal of the compressor through the power terminal 11 to ensure normal startup and operation of the compressor.

They are only for the purpose of facilitating the explanation of the scheme of the utility model and simplifying the description, rather than explicitly or implicitly indicating that the devices or elements involved must have the specific orientation, be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms cannot be understood or interpreted as limitations on the scheme of the utility model.
