Description

Technical Field

[0001] This utility model relates to the field of washing machine accessories, and in particular to a snap-fit ​​structure for a drain auger harness. Background Technology

[0002] During the operation of a washing machine, the drain actuator plays a crucial role in draining the water. When the washing machine performs a drain operation, the inner tub is rotating, and the power cord of the drain actuator is inevitably subjected to a certain degree of tension. This tension can affect the solder joints between the actuator wiring harness and the machine, potentially causing them to detach. Once the solder joints detach, it will lead to poor electrical contact, causing the drain actuator to fail to operate properly, ultimately resulting in the washing machine's drainage function failing.

[0003] To effectively avoid such adverse situations, the current common practice is to fix the traction device wiring harness to the machine body. This method transfers the stress point, preventing the welding points of the traction device wiring harness from directly bearing tensile force during washing machine operation, thus ensuring the stability of the welding points and the normal operation of the drain traction device.

[0004] Currently, the fixing method of the drain actuator in mass-produced products has certain limitations. The actuator cover plate is designed with round holes on both sides. When fixing the actuator wiring harness, nylon wire clips are needed to bind it, thereby fixing the wiring harness to the actuator body. This fixing method has revealed many problems in actual operation. On the one hand, after using nylon wire clips to bind the wiring harness, the excess part of the nylon clips needs to be cut off. This operation is not only cumbersome, but also greatly affects production efficiency. On the other hand, it is difficult to accurately control the tightness of the nylon wire clips. If the binding is too loose, the expected fixing effect cannot be achieved, and the wiring harness may still be pulled during the operation of the washing machine, causing the solder joints to detach; if the binding is too tight, it is easy to damage the wiring harness, which may lead to risks such as leakage or poor power supply, which may also cause the drain actuator to fail to pull or malfunction.

[0005] In summary, the existing wiring harness fixing method for the drain actuator has many drawbacks, and it is urgent to redesign the actuator body structure and change the wiring harness fixing method to effectively solve the problem of poor wiring harness bundling and improve the reliability and stability of the washing machine drain actuator. Utility Model Content

[0006] This invention provides a wire harness snap-in structure for a drain actuator, which can solve the problems of cumbersome operation and poor wire harness bundling in the prior art, improve production efficiency, and enhance the reliability and stability of the washing machine drain actuator.

[0007] A wire harness snap-in structure for a drainage traction device includes a traction device body and a wire harness. The traction device body has snap-in structures symmetrically fixed on both sides. Each snap-in structure includes at least one snap-in space for embedding the wire harness, and the minimum radial dimension of the snap-in space is smaller than the diameter of the wire harness. The wire harness is clamped and fixed by elastic deformation after passing through the snap-in space.

[0008] Furthermore, the engaging structure includes a engaging unit, which includes a horizontally extending connecting portion and a limiting portion formed by vertical bending from the end of the connecting portion. The connecting portion is fixed to the side wall of the traction device body, and the engaging space is formed between the limiting portion and the side wall of the traction device body.

[0009] Furthermore, the limiting part bends upward from the end of the connecting part, and the opening direction of the snap-fit ​​space is set upward.

[0010] Furthermore, the limiting part bends downward from the end of the connecting part, and the opening direction of the snap-fit ​​space is set downward.

[0011] Furthermore, the distance between the limiting part and the side wall of the traction device body is less than the diameter of the wire harness.

[0012] Furthermore, the end of the limiting part is inclined toward the side wall of the traction device body to form a guide slope.

[0013] Furthermore, the snap-fit ​​structure includes at least three snap-fit ​​units, each of which includes a horizontally extending connecting portion and a limiting portion integrally formed with the end of the connecting portion, and multiple snap-fit ​​units are arranged in sequence to form a continuous S-shaped wiring channel.

[0014] Furthermore, the plurality of connecting parts are a first connecting arm and a second connecting arm arranged vertically opposite each other, and a central connecting arm located between the first connecting arm and the second connecting arm. The first connecting arm and the second connecting arm extend horizontally from the side wall of the traction device body and then bend towards each other to form the limiting part. The end of the central connecting arm is provided with an arc-shaped limiting part.

[0015] Furthermore, the diameter of the limiting portion on the central connecting arm is greater than the maximum radial dimension of the central connecting arm.

[0016] Furthermore, the distance between the limiting part and the side wall of the traction device body is less than the diameter of the wire harness, and the distance between the first connecting arm, the central connecting arm and the second connecting arm is also less than the diameter of the wire harness.

[0017] The beneficial effects of this utility model are:

[0018] This utility model provides a snap-fit ​​structure for a drainage traction device's wiring harness, comprising a traction device body and a wiring harness. The traction device body has symmetrically fixed snap-fit ​​structures on both sides. Each snap-fit ​​structure includes at least one snap-fit ​​space for embedding the wiring harness, and the minimum radial dimension of the snap-fit ​​space is smaller than the diameter of the wiring harness. The wiring harness is clamped and fixed by its elastic deformation after passing through the snap-fit ​​space. The snap-fit ​​structure utilizes the dimensional difference between the snap-fit ​​space and the wiring harness diameter, employing the clamping force generated by the elastic deformation of the wiring harness itself to achieve fixation. This eliminates the need for nylon wire clips and the need to cut off excess material, completely solving the problem of cumbersome procedures in existing technologies and simplifying the installation process to direct snap-fit, significantly improving production efficiency.

[0019] Meanwhile, the limiting design of the snap-fit ​​space can transfer the stress point from the welding point to the snap-fit ​​structure, effectively resisting the pulling force during the operation of the washing machine, preventing the welding point from coming apart due to direct force, and eliminating the need to apply additional binding force. There is no problem with tightness control, so it will not cause fixing failure due to being too loose, nor will it cause damage to the wiring harness due to being too tight. The structural design eliminates the risk of leakage or poor power supply, reduces the overall failure rate of the traction device, and further improves the reliability and stability of the drainage traction device.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This utility model provides a wire harness snap-in structure for a drainage traction device, including a traction device body 1 and a wire harness 2. The traction device body 1 is symmetrically fixed with snap-in structures 3 on both sides. The snap-in structure 3 includes at least one snap-in space 4 for the wire harness 2 to be inserted, and the minimum radial dimension of the snap-in space 4 is smaller than the diameter of the wire harness 2. The wire harness 2 is clamped and fixed by elastic deformation after passing through the snap-in space 4.

[0033] Example 1

[0034] like Figures 1-3 As shown, this embodiment demonstrates a single-wire clamping effect. The clamping structure 3 includes a clamping unit, which comprises a horizontally extending connecting portion 5 and a limiting portion 6 formed by a vertical bend from the end of the connecting portion 5. The connecting portion 5 is fixed to the side wall of the traction device body 1. Specifically, the limiting portion 6 bends upward from the end of the connecting portion 5, forming a clamping space 4 between the limiting portion 6 and the side wall of the traction device body 1. The opening of the clamping space 4 faces upward. Simultaneously, the distance between the limiting portion 6 and the side wall of the traction device body 1 is less than the diameter of the wire harness 2. The elastic deformation of the wire harness 2 after clamping is used to fix the wire harness 2, improving the clamping stability. The end of the limiting portion 6 is inclined towards the side wall of the traction device body 1 to form a guide slope 7, which is used to guide the wire harness 2 from the clamping opening of the clamping space 4 during installation, reducing the installation difficulty and improving production efficiency.

[0035] Example 2

[0036] like Figures 4-6As shown, this embodiment features a single-wire locking effect. The locking structure 3 includes a locking unit, which comprises a horizontally extending connecting portion 5 and a limiting portion 6 formed by a vertical bend from the end of the connecting portion 5. The connecting portion 5 is fixed to the side wall of the actuator body 1. Unlike embodiment 1, the limiting portion 6 bends downward from the end of the connecting portion 5, forming a locking space 4 between the limiting portion 6 and the side wall of the actuator body 1. The opening of the locking space 4 faces downward. Simultaneously, the distance between the limiting portion 6 and the side wall of the actuator body 1 is less than the diameter of the wire harness 2. The end of the limiting portion 6 is inclined towards the side wall of the actuator body 1, forming a guide slope 7. This embodiment adopts a downward-facing opening design, which can be flexibly selected according to the installation position of the actuator body 1 inside the washing machine and the routing of the wire harness 2, meeting different layout requirements and enhancing the applicability of the structure. At the same time, a downward-facing opening may reduce the probability of dust, debris, etc., entering the locking space 4, ensuring the durability of the fixing effect to a certain extent.

[0037] Example 3

[0038] like Figures 7-9 As shown, this embodiment features a double-locking wire effect. The locking structure 3 includes at least three locking units, and in this embodiment, three are provided. Each locking unit includes a horizontally extending connecting part 5 and a limiting part 6 integrally formed with the end of the connecting part 5. The three locking units are arranged sequentially to form a continuous S-shaped wiring channel. The three connecting parts 5 are a first connecting arm 51 and a second connecting arm 53 arranged vertically opposite each other, and a central connecting arm 52 located between the first connecting arm 51 and the second connecting arm 53. The first connecting arm 51 and the second connecting arm 53 extend horizontally from the side wall of the actuator body 1 and then bend towards each other to form the limiting part 6. The end of the central connecting arm 52 is provided with an arc-shaped limiting part 6 with a diameter larger than its maximum radial dimension. Therefore, it can limit the wire harness 2 in the horizontal direction and prevent displacement during the operation of the washing machine. The distance between the limiting part 6 and the side wall of the actuator body 1 is less than the diameter of the wire harness 2. The distances between the first connecting arm 51, the central connecting arm 52, and the second connecting arm 53 are all less than the diameter of the wire harness 2, which enhances the fixing effect of the wire harness 2.

[0039] During installation, the wire harness 2 passes sequentially through each snap-fit ​​unit along the S-shaped wiring channel. Utilizing the snap-fit ​​space 4 formed by the limiting part 6 of each snap-fit ​​unit and the side wall of the machine body, as well as the distance limitation between each connecting arm, the wire harness 2 is fixed in multiple directions through elastic deformation. The three snap-fit ​​units form a continuous S-shaped channel, limiting and clamping the wire harness 2 from multiple directions. Compared to single-wire snaps, this more effectively resists pulling forces in various directions, greatly improving the stability of the wire harness 2's fixation. Furthermore, the arc-shaped limiting part 6 at the end of the central connecting arm 52 can limit the wire harness 2 horizontally. Combined with the distance limitation between each connecting arm, this effectively prevents the wire harness 2 from shifting during washing machine operation, ensuring long-term stability of the fixation. Simultaneously, the arc-shaped design allows the wire harness 2 to smoothly enter the snap-fit ​​space 4, reducing resistance during installation. The S-shaped channel design, while ensuring a secure fixation, does not excessively increase installation difficulty, balancing installation efficiency and fixation reliability.
