Technical Field
[0001] This utility model relates to the field of home appliance manufacturing technology, specifically to an integrated wiring harness for home appliances. Background Technology
[0002] In the home appliance manufacturing industry, with the increasing diversification and intelligence of home appliance functions, the number of wiring harnesses required inside home appliances is constantly increasing.
[0003] Traditional household wiring harnesses are usually arranged in a decentralized manner, lacking an effective integrated structure between the main harness and the secondary harnesses. This makes the harnesses prone to tangling and crossing during installation, which not only increases the difficulty and time cost of assembly, but also easily leads to short circuits, open circuits and other faults due to messy wiring.
[0004] Furthermore, existing wiring harness connection structures have poor stability. During the operation of home appliances, external forces such as vibration and pulling can easily cause the connections between the wiring harnesses to loosen or even detach, affecting the normal operation and lifespan of the appliances. In addition, when a part of the wiring harness fails, due to the lack of modular design, repair personnel often need to check and replace the entire wiring harness system, resulting in low repair efficiency and high repair costs.
[0005] In view of this, we propose an integrated wiring harness for home appliances. Utility Model Content
[0006] To overcome the above shortcomings, this utility model provides an integrated wiring harness for home appliances.
[0007] The technical solution of this utility model is:
[0008] An integrated wiring harness for home appliances includes several harness bodies, each comprising a main harness and several secondary harnesses. An integrated frame is mounted on each harness body. The integrated frame includes a central sleeve located outside the main harness and an eccentric sleeve located outside the secondary harnesses. Several inserts are integrally formed on the outer circumference of the central sleeve, and a plug is integrally formed on the outer wall of the eccentric sleeve. The plug has a T-shaped cross-section and a limiting bracket is installed at both ends of the integrated frame. The limiting bracket is detachably fixed to the integrated frame. Through the integrated frame, the main and secondary harnesses are modularly connected: the central sleeve and the eccentric sleeve are stably connected via the T-shaped structure of the inserts and slots, forming a flexibly assembleable harness module. This structure ensures both the orderly spatial arrangement of the harnesses and facilitates rapid assembly during production and individual replacement during later maintenance. The detachable design of the limit bracket further enhances the stability of the structure and prevents the sleeve from loosening during long-term use.
[0009] As a preferred technical solution, the length of the insertion block is equal to the length of the insertion strip and both are equal to the length of the central sleeve. This ensures that the insertion part provides support along its entire length.
[0010] As a preferred technical solution, the limiting frame includes two symmetrically arranged tiles and two symmetrically arranged central limiting blocks, with a connecting rod fixedly connected between the central limiting blocks and the tiles. The symmetrically arranged tiles and central limiting blocks form a rigid frame through the connecting rod, constraining the radial displacement of the eccentric sleeve and effectively preventing direct relative displacement between the central sleeve and the eccentric sleeve.
[0011] As a preferred technical solution, when the limiting frame is installed on the integrated frame, both ends of the plug are tightly fitted with the central limiting blocks located on both sides of the limiting frame. The tight fit between the two ends of the plug and the central limiting blocks further restricts axial sliding between the plug and the slot. This design is particularly important in dynamic environments, preventing loosening of the connection due to equipment vibration and ensuring the long-term reliability of the wiring harness connection.
[0012] As a preferred technical solution, each of the central limiting blocks is fixedly connected to a semi-circular connecting ring. When two tiles are connected, the two connecting rings merge. A connecting groove for threaded connection with the connecting ring is provided on the inner ring wall of the central sleeve. The threaded engagement between the semi-circular connecting ring and the central sleeve not only provides reliable connection strength but also facilitates assembly and disassembly. When the two connecting rings merge to form a complete threaded structure, it ensures coaxiality with the central sleeve and prevents loosening through the self-locking characteristic of the thread.
[0013] As a preferred technical solution, when the limiting frame is installed on the integrated frame, the outermost outer ring wall of the eccentric sleeve is in close contact with the inner ring wall of the tile, and both the inner ring wall of the tile and the outer ring wall of the eccentric sleeve are provided with anti-slip teeth. The anti-slip tooth structure of the inner ring wall of the tile and the outer ring wall of the eccentric sleeve forms a mechanical engagement when the two are in close contact, which significantly increases the friction.
[0014] As a preferred technical solution, each end of the tile has an integrally formed extension plate, and the two opposing extension plates are fixedly connected by two symmetrically arranged fixing bolts. The combination of the extension plates and fixing bolts provides an adjustable clamping force, which not only ensures the effective constraint of the tile on the eccentric sleeve, but also facilitates adjustment according to different specifications of wire harnesses.
[0015] As a preferred technical solution, the diameter of the inner ring wall of the connecting ring is equal to the inner diameter of the central sleeve. This avoids the connecting ring affecting the installation of the main wire harness.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] This invention utilizes an integrated frame to achieve modular connection between the main and secondary wire harnesses. The central and eccentric sleeves are stably connected via a T-shaped structure of inserts and slots, forming a flexibly assembleable wire harness module. This structure ensures both the orderly spatial arrangement of the wire harnesses and facilitates rapid assembly during production and individual replacement during later maintenance. The detachable design of the limiting frame further enhances the structural stability, preventing the sleeves from loosening during long-term use. Attached Figure Description

[0025] 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.
[0026] Please see Figures 1-5 This utility model provides a technical solution:
[0027] An integrated wiring harness for home appliances includes several harness bodies 1. Each harness body 1 includes a main harness and several secondary harnesses. An integrated frame 2 is mounted on each harness body 1. The integrated frame 2 includes a central sleeve 20 located outside the main harness and an eccentric sleeve 21 located outside the secondary harnesses. Several inserts 22 are integrally formed on the outer circumference of the central sleeve 20. An insert block 23 is integrally formed on the outer wall of the eccentric sleeve 21. The insert block 23 has a slot for engaging with the inserts 22. The insert block 23 has a T-shaped cross-section. A limiting frame 3 is installed at both ends of the integrated frame 2. The limiting frame 3 is detachably fixed to the integrated frame 2. Through the integrated frame 2, the main harness and secondary harnesses are modularly connected: the central sleeve 20 and the eccentric sleeve 21 are stably connected through the T-shaped structure of the inserts 22 and the slots, forming a flexibly assembleable harness module. This structure ensures both the orderly spatial arrangement of the wire harness and facilitates rapid assembly during production and individual replacement during later maintenance. The detachable design of the limit bracket 3 further enhances the stability of the structure and prevents the sleeve from loosening during long-term use.
[0028] In this preferred embodiment, the length of the insertion block 23 is equal to the length of the insertion strip 22 and both are equal to the length of the central sleeve 20. This provides support for the insertion part along its entire length.
[0029] In a preferred embodiment, the limiting frame 3 includes two symmetrically arranged tiles 30 and two symmetrically arranged central limiting blocks 31. A connecting rod 32 is fixedly connected between the central limiting blocks and the tiles 30. The symmetrically arranged tiles 30 and central limiting blocks 31 form a rigid frame through the connecting rod 32, which constrains the radial displacement of the eccentric sleeve 21 and can effectively prevent the central sleeve 20 and the eccentric sleeve 21 from directly generating relative displacement.
[0030] In this preferred embodiment, when the limiting frame 3 is installed on the integrated frame 2, both ends of the plug 23 are tightly fitted with the central limiting block 31 located on both sides of the limiting frame 3. The tight fit between the two ends of the plug 23 and the central limiting block 31 further restricts the axial sliding between the plug strip 22 and the slot. This design is particularly important in dynamic environments, preventing loosening of the connection due to equipment vibration and ensuring the long-term reliability of the wiring harness connection.
[0031] In a preferred embodiment, each central limiting block 31 is fixedly connected to a semi-circular connecting ring 33. When two tiles 30 are connected, the two connecting rings 33 merge, and a connecting groove 200 is provided on the inner ring wall of the central sleeve 20 for threaded connection with the connecting ring 33. The threaded engagement between the semi-circular connecting ring 33 and the central sleeve 20 not only provides reliable connection strength but also facilitates assembly and disassembly. When the two connecting rings 33 merge, they form a complete threaded structure, which ensures coaxiality with the central sleeve 20 and prevents loosening through the self-locking characteristic of the thread.
[0032] In this preferred embodiment, when the limiting frame 3 is installed on the integrated frame 2, the outermost outer ring wall of the eccentric sleeve 21 is in close contact with the inner ring wall of the tile 30, and both the inner ring wall of the tile 30 and the outer ring wall of the eccentric sleeve 21 are provided with anti-slip teeth. The anti-slip tooth structure of the inner ring wall of the tile 30 and the outer ring wall of the eccentric sleeve 21 forms a mechanical engagement when the two are in close contact, which significantly increases the friction.
[0033] In a preferred embodiment, each end of the tile 30 has an integrally formed extension plate 34, and the two opposing extension plates 34 are fixedly connected by two symmetrically arranged fixing bolts 35. The combination of the extension plate 34 and the fixing bolts 35 provides an adjustable clamping force, which can not only ensure the effective constraint of the tile 30 on the eccentric sleeve 21, but also facilitate adjustment according to different specifications of wire harnesses.
[0034] As a preferred embodiment, the inner diameter of the connecting ring 33 is equal to the inner diameter of the central sleeve 20. This avoids the connecting ring 33 affecting the installation of the main wiring harness.
[0035] When using the integrated wiring harness for home appliances of this utility model, the main wiring harness is first inserted into the central sleeve 20, and the secondary wiring harness is inserted into the eccentric sleeve 21. The insert strip 22 on the central sleeve 20 and the slot of the T-shaped insert block 23 on the eccentric sleeve 21 are used to connect with each other, so that the main wiring harness and the secondary wiring harness form a modular connection, realize the orderly arrangement of the wiring harness, and facilitate quick assembly and subsequent maintenance and replacement.
[0036] After assembly, limit brackets 3 are installed at both ends of the integrated frame 2. Two symmetrical tiles 30 are placed around the eccentric sleeve 21, so that the inner ring wall of the tile 30 and the anti-slip teeth of the outer ring wall of the eccentric sleeve 21 are tightly engaged, increasing friction to prevent the eccentric sleeve 21 from rotating or sliding; at the same time, the central limit block 31 is connected to the tile 30 through the connecting rod 32, and the central limit block 31 is tightly fitted to both ends of the insertion block 23, restricting the axial sliding between the insertion strip 22 and the slot, and avoiding loosening of the insertion due to equipment vibration.
[0037] Subsequently, the extended plates 34 at both ends of the tile 30 are fixed with fixing bolts 35, and the clamping force is adjusted to ensure that the tile 30 effectively constrains the eccentric sleeve 21. This can be adjusted according to different specifications of wire harnesses. After the semi-circular connecting rings 33 on the two center limiting blocks 31 are merged, they are threadedly connected to the connecting groove 200 on the inner ring wall of the center sleeve 20 to ensure coaxiality with the center sleeve 20. The self-locking thread prevents loosening and further enhances the overall structural stability.
[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
