Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and in particular to a compressor motor lead wire mounting structure and a compressor including the compressor motor lead wire mounting structure. Background Technology

[0002] like Figure 1 As shown, in the prior art, the socket 1 used in the motor lead wire installation structure of the compressor is located inside the motor end cover. The socket 1 has three lead wire channels 11 inside, each passing through the side of the socket 1 facing the motor end cover and connected to the corresponding terminals on the motor end cover. The three-phase leads of the motor pass through the three lead wire channels 11 inside the socket 1 and are connected to the outside through the terminals on the motor end cover. Using this socket 1 to install the lead wires, the portion of the lead wire extending out of the socket 1 to connect to the motor windings (i.e., the portion of the lead wire extending out of the lead wire channel 11 away from the terminals on the motor end cover) is in a free-extending state. This lead wire exit method results in insufficient safety distance between the lead wire and the motor rotor and exhaust pipe, which can easily lead to damage and leakage of the lead wire, affecting the operating safety of the compressor. Utility Model Content

[0003] In view of the above-mentioned defects in the prior art, the technical problem to be solved by this utility model is to provide a compressor motor lead wire mounting structure that can avoid the risk of interference between the lead wire and the motor rotor and exhaust pipe.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model provides a compressor motor lead wire installation structure, including a socket and a guide. The socket has a lead wire channel inside for passing the lead wire through. One end of the lead wire channel is an extension port for the lead wire to extend out of the socket to connect with the motor winding. The end where the extension port is located is the extension end of the socket. The guide is located at the extension end of the socket and forms a wire harness channel that communicates with the extension port. The lead wire extending out of the socket from the extension port passes through the wire harness channel and is constrained by the wire harness channel to be arranged along the designed path.

[0006] Preferably, the end of the cable routing channel furthest from the socket is smaller than the end of the cable routing channel closest to the socket.

[0007] Preferably, the cross-sectional area of ​​the wire harness channel gradually decreases in the direction away from the socket.

[0008] Preferably, the size of one end of the cable routing channel near the socket matches the size of the socket's protruding end.

[0009] Preferably, the wire harness channel is a U-shaped groove, and the guide includes a base plate, a first side plate and a second side plate. The first side plate and the second side plate are disposed opposite each other on both sides of the base plate and form a U-shaped groove between the base plate and the base plate.

[0010] Preferably, the first side plate is arranged parallel to the direction in which the lead wire extends out of the socket, and the second side plate is arranged inclined toward the first side plate in the direction away from the socket.

[0011] Preferably, the second side plate extends in a curved shape in the direction away from the socket.

[0012] Preferably, a slot is provided on the second side plate.

[0013] Preferably, the extension dimension of the base plate in the direction away from the socket is 5mm-15mm, the extension dimension of the end of the base plate away from the socket between the first side plate and the second side plate is 5mm-10mm, and the extension height of the first side plate and the second side plate relative to the base plate is 5mm-10mm.

[0014] This utility model also provides a compressor, including the compressor motor lead wire mounting structure as described above.

[0015] Compared with the prior art, this utility model has significant progress:

[0016] This utility model discloses a compressor motor lead wire installation structure. A guide with a wire harness channel is added to the extended end of the socket. The lead wire extending from the socket through the lead wire channel passes through the wire harness channel of the guide. The wire harness channel of the guide allows adjustment of the lead wire's exit position and direction, constraining the lead wire's path and ensuring it follows a fixed, designed path. This avoids interference between the lead wire and the motor rotor or exhaust pipe, preventing lead wire damage and leakage, and improving compressor operating safety. In application, the length and outlet direction of the wire harness channel of the guide can be adjusted according to different compressor and motor models to adapt this utility model's compressor motor lead wire installation structure to various compressor and motor models, eliminating the risk of interference between the lead wire and the motor rotor or exhaust pipe in various compressor and motor models.

[0033] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. These embodiments are only used to illustrate this utility model and are not intended to limit it.

In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0037] like Figure 2 and Figure 3 The image shows one embodiment of the compressor motor lead wire mounting structure of this utility model. The compressor motor lead wire mounting structure of this embodiment includes a socket 1 and a guide member 2.

[0038] The socket 1 has internal lead channels 11 for passing through the lead wires 3. Multiple lead channels 11, such as three, can be provided to pass through the three-phase lead wires 3 of the motor respectively. One end of the lead channel 11 is an extension port 11a for the lead wire 3 to extend out of the socket 1 to connect to the motor windings. The other end of the lead channel 11 is a connecting port 11b that passes through the side of the socket 1 facing the motor end cover and is connected to the terminals on the motor end cover. The end of the lead channel 11 with its extension port 11a is the extension end 1a of the socket 1, and the extension ports 11a of the multiple lead channels 11 are all located on the same extension end 1a of the socket 1. The connecting ports 11b of the multiple lead channels 11 are also all located on the same side of the socket 1.

[0039] The guide member 2 is provided at the extended end 1a of the socket 1. The guide member 2 is connected and fixed to the extended end 1a of the socket 1. The guide member 2 forms a wire harnessing channel 21 that communicates with the extended port 11a of the lead wire channel 11 in the socket 1. The lead wire 3 of the socket 1 extends out from the extended port 11a of the lead wire channel 11 and is connected to the motor winding after passing through the wire harnessing channel 21 of the guide member 2. The lead wire 3 of the socket 1 extends out from the extended port 11a of the lead wire channel 11 and is arranged along the designed path within the wire harnessing channel 21 of the guide member 2, constrained by the wire harnessing channel 21.

[0040] In this embodiment, the compressor motor lead wire mounting structure adds a guide member 2 with a wire harness channel 21 to the protruding end 1a of the socket 1. This allows the lead wire 3 extending from the protruding port 11a of the lead wire channel 11 of the socket 1 to pass through the wire harness channel 21 of the guide member 2. The wire harness channel 21 of the guide member 2 allows adjustment of the exit position and direction of the lead wire 3 extending from the socket 1, constraining the routing path of the lead wire 3. This ensures that the lead wire 3 is arranged along a fixed, designed path, thereby preventing interference between the lead wire 3 and the motor rotor or exhaust pipe, preventing damage and leakage of the lead wire 3, and improving the operating safety of the compressor. In application, the length and outlet direction of the wire harness channel 21 of the guide member 2 can be adjusted according to different compressor and motor models to adapt the compressor motor lead wire mounting structure of this embodiment to different compressor and motor models, eliminating the risk of interference between the lead wire 3 and the motor rotor or exhaust pipe in various compressor and motor models.

[0041] In this embodiment, preferably, the end of the guide 21 away from the socket 1 is smaller than the end of the guide 21 near the socket 1, so as to effectively constrain the lead wire 3 in the direction of the lead wire 3 extending out of the socket 1.

[0042] Preferably, the cross-sectional area of ​​the wire harness channel 21 of the guide member 2 gradually decreases in the direction away from the socket 1. The wire harness channel 21 gradually shrinks from the larger end away from the socket 1 to the smaller end closer to the socket 1, which is conducive to gradually gathering and constraining the lead wire 3 extending from the extension end 1a of the socket 1, and smoothly changing the exit position and exit direction of the lead wire 3 extending from the socket 1.

[0043] In this embodiment, preferably, the size of one port of the guide 2’s wire channel 21 near the socket 1 matches the size of the socket 1’s protruding end 1a, which is beneficial to the fact that all the lead wires 3 extending from the protruding ports 11a of all the lead channels 11 located on the protruding end 1a of the socket 1 are accommodated in the guide 2’s wire channel 21.

[0044] See Figure 3 In this embodiment, preferably, the wire harness channel 21 is a U-shaped groove. The guide member 2 includes a base plate 22, a first side plate 23, and a second side plate 24. The base plate 22 is connected to the side of the protruding end 1a of the socket 1 away from the motor end cover (i.e., the side opposite to the side where the connection port 11b of the lead wire channel 11 on the socket 1 is located). The first side plate 23 and the second side plate 24 are disposed opposite each other on both sides of the base plate 22 and form a U-shaped groove between them. The U-shaped groove opens towards the motor end cover, i.e., towards the side where the connection port 11b of the lead wire channel 11 on the socket 1 is located. The wire harness channel 21 in the form of a U-shaped groove in the guide member 2 is more conducive to the installation of the lead wire 3.

[0045] Preferably, the first side plate 23 of the guide member 2 is arranged parallel to the direction in which the lead wire 3 extends out of the socket 1, and the second side plate 24 is inclined toward the first side plate 23 in the direction away from the socket 1, so that the cross-sectional area of ​​the wire harness channel 21 gradually decreases in the direction away from the socket 1.

[0046] Better, such as Figure 2 As shown, the second side plate 24 of the guide 2 extends in a curved shape along the direction away from the socket 1, which is more conducive to optimizing the routing path of the lead wire 3.

[0047] Better, such as Figure 3 As shown, the second side plate 24 of the guide member 2 has a slot 25, which facilitates the installation of the lead wire 3.

[0048] Preferably, the extension dimension of the base plate 22 of the guide member 2 along the direction away from the socket 1 is L = 5mm-15mm, where L is the collinear length of the base plate 22 and the first side plate 23, and / or the collinear length of the base plate 22 and the second side plate 24. The extension dimension of the end of the base plate 22 away from the socket 1 between the first side plate 23 and the second side plate 24 is D = 5mm-10mm, and the extension height of the first side plate 23 and the second side plate 24 relative to the base plate 22 is H = 5mm-10mm. The extension dimension D of the end of the base plate 22 away from the socket 1 between the first side plate 23 and the second side plate 24 is smaller than the extension dimension D of the end of the base plate 22 near the socket 1 between the first side plate 23 and the second side plate 24, such that the end of the U-shaped groove away from the socket 1 is smaller than the end of the U-shaped groove near the socket 1. The extension dimension of the base plate 22 near the socket 1 between the first side plate 23 and the second side plate 24 matches the dimension of the protruding end 1a of the socket 1, so that the dimension of the U-shaped groove near the socket 1 matches the dimension of the protruding end 1a of the socket 1. Depending on different compressor and motor models, the dimensions of the base plate 22, the first side plate 23, and the second side plate 24 of the guide member 2 can be adaptively adjusted to adjust the length and outlet direction of the U-shaped groove, so that the compressor motor lead wire mounting structure of this embodiment can be adapted to different compressor and motor models.

[0049] Based on the compressor motor lead wire mounting structure of this utility model, this utility model embodiment also provides a compressor, which includes the compressor motor lead wire mounting structure described above.

[0050] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
