Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and in particular to a wire harness fixing structure and a compressor. Background Technology

[0002] During compressor manufacturing, the copper wire wound around the coil needs to be led out. After the lead-out wire is connected to the housing cover, it may deform, causing it to come into contact with the rotor or oil baffle, ultimately leading to wear or breakage of the lead-out wire surface. Currently, the lead-out wire is fixed in place by pressing, but vibrations during compressor movement or installation can cause the lead-out wire to come into contact with the rotor, resulting in wear of the lead-out wire sheath and ultimately a short circuit. Utility Model Content

[0003] The purpose of this invention is to provide a wire harness fixing structure and a compressor, which solves the problem that the lead wires are prone to wear or breakage during the fixing process in the prior art.

[0004] To achieve this objective, the present invention adopts the following technical solution: The present invention provides a wire harness fixing structure, including a coil frame, on which a first groove and a second groove are provided.

[0021] The embodiments of this utility model are described in detail below.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0022] To solve the above problems, such as Figures 1 to 2As shown, this utility model provides a wire harness fixing structure, including a coil frame 1. The coil frame 1 has a first groove 11 and a second groove 12, which are located on the upper end face of the coil frame 1. A retaining part 2 is provided on the outer wall of the coil frame 1. The retaining part 2 is installed between the first groove 11 and the second groove 12. A slot is provided in the retaining part 2 along the axial direction of the coil frame 1. A portion of the wire passes through the first groove 11 from the coil frame 1 and is inserted into the slot. Another portion of the wire passes through the second groove 12 from the coil frame 1 and is inserted into the slot. Typically, a first wire 3 and a third wire 5 are disposed in the first groove, while a second wire 4 is typically disposed in the second groove 12. The first wire 3, second wire 4, and third wire 5 are inserted into the slot. The compressor includes a top cover and a stator core. Lead wires are led out from the stator core and connected to the top cover. The coil frame 1 is mounted on the stator core. The aforementioned wires, typically the first wire 3, second wire 4, and third wire 5, are wound around the inner side of the coil frame 1.

[0023] A first groove 11 and a second groove 12 are provided on the upper side of the coil frame 1. A retaining part 2 is installed between the first groove 11 and the second groove 12. The first wire 3 and the third wire 5 pass through the first groove 11, and the second wire 4 passes through the second groove 12. Then, the first wire 3, the second wire 4 and the third wire 5 can all be gathered in the retaining part 2, and finally a lead wire is formed on the upper side of the retaining part 2. Since the lead wire is set on the outside of the coil frame, away from the rotor and other components rotating inside the coil frame 1, the probability of the lead wire being worn is reduced, and the lead wire can be stably fixed, so that the compressor can run stably for a long time without short circuit.

[0024] The retaining part 2 includes a first sidewall 21, a second sidewall 22 and a third sidewall 23. The first sidewall 21 is connected to the coil frame 1, the second sidewall 22 is connected to the first sidewall 21, and the third sidewall 23 is connected to the second sidewall 22. A gap is left between the third sidewall 23 and the outer wall of the coil frame 1, and all the wires of the first groove 11 and the second groove 12 can pass through the gap.

[0025] In this invention, a notch is formed between the third sidewall 23 of the retaining part 2 and the outer wall of the coil frame 1. The first wire 3, the second wire 4 and the third wire 5, which are led out from the first groove 11 and the second groove 12, are introduced into the notch and pass through the slot in the retaining part 2 along the axial direction of the coil fastener. This invention can constrain the first wire 3, the second wire 4 and the third wire 5 through three sets of sidewalls. The structure of the retaining part 2 is simpler and easier to complete injection molding.

[0026] The first sidewall 21 and the third sidewall 23 are parallel, and the second sidewall 22 is perpendicular to both the first sidewall 21 and the third sidewall 23. The cross-sectional shape of the holding part 2 along the axial direction of the coil frame 1 is approximately U-shaped, wherein the third sidewall 23 is shorter, leaving a gap for the insertion of the first wire 3, the second wire 4 and the third wire 5. The parallel relationship between the first sidewall 21 and the third sidewall 23 can reserve more space for the holding part 2, making it easier to put the first wire 3, the second wire 4 and the third wire 5 of different thicknesses into the holding part 2.

[0027] The bottom surface of the first groove 11 is lower than the lower edge of the retaining part 2. After the first wire 3 and the third wire 5 are introduced, they can be directly inserted from the bottom of the retaining part 2, reducing the bending length of the first wire 3 and the third wire 5, so that the first wire 3 and the third wire 5 can smoothly enter the retaining part 2, and avoid excessive deformation of the first wire 3 and the third wire 5.

[0028] The first groove 11 is elongated, which facilitates the processing of the coil frame 1, reduces the processing difficulty of the first groove 11, and facilitates subsequent mass production.

[0029] The bottom surface of the second groove 12 is lower than the lower edge of the retaining part 2. After the second wire 4 is introduced, it can be directly inserted from the bottom of the retaining part 2, reducing the bending length of the second wire 4 and allowing the second wire 4 to smoothly enter the retaining part 2, thus avoiding excessive deformation of the second wire 4.

[0030] The second groove 12 is L-shaped and includes a vertical groove 121 and a horizontal groove 122. The vertical groove 121 is parallel to the axis of the coil frame 1, and the horizontal groove 122 is bent toward the holding part 2. Since the third side wall 23 is close to the second groove 12, in order to fix the second wire 4, the second wire 4 needs to be wound around the horizontal groove 122 through the vertical groove 121 to achieve pre-fixation of the second wire 4. Then the second wire 4 is introduced into the holding part 2 to achieve re-fixation of the second wire 4.

[0031] The first groove 11 and the second groove 12 have the same cross-sectional width, which facilitates the use of the same tool for mass production and reduces processing costs.

[0032] The end of the wire away from the coil frame 1 is sleeved in the protective shell, and the protective shell is connected to the power supply on the top cover to provide current to the wire.

[0033] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
