Abstract
Description
Technical Field
[0001] This application relates to the field of sealing technology, and in particular to a sealed and waterproof cable outlet shell structure. Background Technology
[0002] With the continuous development of the home appliance industry, refrigerators, as indispensable household appliances, are constantly improving in performance and functionality. Refrigerators contain numerous components, and the normal operation of these components relies on a large number of wiring harnesses for power transmission and signal transmission. Properly organizing and managing these wiring harnesses is crucial for the stable operation of the refrigerator. At the same time, the refrigerator's insulation performance is also one of the key indicators of its quality, and foaming to form an insulation layer is a common and important method. Good wiring harness organization and insulation measures can improve the refrigerator's energy efficiency, extend its service life, and provide users with a better user experience. In traditional refrigerator manufacturing, the management of numerous wire harnesses typically involved simply grouping them together, sometimes using ordinary cable ties to bind them and prevent them from becoming loose. When forming the insulation layer with foam, the wiring exit points were merely partially covered by the outer casing. For sealing and waterproofing, ordinary sealant was usually applied to the wiring exit points, or simple gaskets were used. These methods provided some degree of organization and basic protection for the wire harnesses.
[0003] However, traditional sealing and waterproofing methods have obvious drawbacks. Ordinary sealants and simple gaskets are insufficient to meet the high sealing and waterproofing requirements inside refrigerators. During long-term use, moisture can easily penetrate and cause malfunctions such as damp wiring harnesses and short circuits, which seriously affect the lifespan and performance of the refrigerator. Therefore, further improvements are needed. Utility Model Content
[0004] To address the above issues, this application provides a sealed and waterproof cable outlet shell structure.
[0005] This application provides a sealed and waterproof cable outlet shell structure, which adopts the following technical solution: A sealed and waterproof cable outlet shell structure includes a shell, wherein a cable outlet groove is provided through the shell along its axis for cable harnesses to pass through, the two ends of the shell are an inlet end and an outlet end, respectively, and a mounting part for installation with a refrigerator is provided near the outlet end of the shell. An annular groove is provided on the outer peripheral wall of the shell near the inlet end, and adhesive tape is wrapped around the shell outside the annular groove. The adhesive tape is used to wrap several cable harnesses.
[0006] By adopting the above technical solution, a groove is provided on the outside of the shell for the tape to be wrapped. Since the tape is used to wrap multiple wire bundles, the tape can wrap several wire bundles together, which can reduce the problem of wire bundles becoming loose. At the same time, it helps to improve the sealing and waterproof performance between the wire outlet shell and the wire bundle, thus meeting the high sealing and waterproof requirements inside the refrigerator.
[0007] Preferably, the housing is provided with a first sealing ring at the inlet end, and the tape is wrapped around the first sealing ring to compress the first sealing ring.
[0008] By adopting the above technical solution, a first sealing ring is wrapped around the inlet end of the housing, and the tape is wrapped around the outside of the first sealing ring to compress the sealing ring. This can enhance the sealing between the inlet end of the outlet housing and the wire harness, effectively prevent moisture from seeping into the interior of the outlet housing from the inlet end, improve the sealing and waterproofing effect of the outlet housing, and meet the high sealing and waterproofing requirements of the refrigerator.
[0009] Preferably, a limiting ring is coaxially sleeved on the outer peripheral wall of the housing.
[0010] By adopting the above technical solution, a limiting ring is coaxially sleeved on the outer peripheral wall of the housing. The limiting ring can limit the tape, the first sealing ring, etc. wrapped on the housing, reduce their displacement during installation or use, ensure the stability and sealing of the cable outlet housing structure, and thus improve the overall sealing and waterproof effect of the cable outlet housing.
[0011] Preferably, the surface of the limiting ring near the outlet end is provided with a sealing element.
[0012] By adopting the above technical solution, a sealing element is set on the surface of the limiting ring near the outlet end, which can further enhance the sealing performance of the outlet shell and the refrigerator installation point after the outlet shell is installed. This effectively prevents moisture from entering the interior of the outlet shell, reduces damage to the wire harness due to contact with moisture, improves the waterproof effect and reliability of the outlet shell structure, and meets the high sealing and waterproof requirements inside the refrigerator.
[0013] Preferably, the housing is provided with an anti-detachment component to prevent the wire harness from detaching from the housing.
[0014] By adopting the above technical solution and setting anti-detachment components inside the housing, the wiring harness can be effectively prevented from detaching from the housing, reducing the possibility of the refrigerator's internal components failing to connect and function properly due to the wiring harness detachment. This ensures stable and reliable electrical connections between the various components inside the refrigerator and guarantees the normal operation of the refrigerator.
[0015] Preferably, the anti-detachment component includes a limiting piece fixedly connected to the housing. Several limiting pieces are spaced apart along the axis of the housing. The inner peripheral wall of the housing between two adjacent limiting pieces has a first anti-slip texture. The free end of the limiting piece away from the housing is inclined toward the end of the cable outlet.
[0016] By adopting the above technical solution, fixedly connected limiting plates are set inside the housing, and several limiting plates are spaced apart along the housing axis, so that the wire harness will be blocked by multiple limiting plates when moving inside the housing. At the same time, a first anti-slip texture is formed on the inner peripheral wall of the housing between two adjacent limiting plates, which increases the friction between the wire harness and the inner wall of the housing, further reducing the slippage of the wire harness. In addition, the free end of the limiting plate away from the housing is inclined towards the exit end. When the wire harness tends to detach from the housing, the inclined limiting plate will generate a reverse resistance on the wire harness, thereby effectively limiting the wire harness from detaching from the housing and improving the stability and reliability of the wire harness in the exit housing structure.
[0017] Preferably, the limiting plates are arranged in several groups along the length direction of the shell, and adjacent groups of limiting plates are staggered.
[0018] By adopting the above technical solution, several sets of limiting plates are arranged along the length of the shell, and adjacent sets are staggered. This can restrict the wire harness passing through the shell from multiple different positions and angles. Compared with a single set of limiting plates, the effect of preventing detachment is greatly enhanced, and the wire harness is more effectively prevented from detaching from the shell, thereby improving the stability and reliability of the wire outlet shell structure.
[0019] Preferably, the limiting piece has a second anti-slip texture on its surface near the wire harness.
[0020] By adopting the above technical solution, a second anti-slip texture is provided on the surface of the limiting piece near the wire harness, which can increase the friction between the limiting piece and the wire harness, thereby more effectively reducing the slippage of the wire harness, further enhancing the role of the anti-detachment component in restricting the wire harness from leaving the housing, improving the fixing effect of the wire outlet housing structure on the wire harness inside the refrigerator, and better meeting the usage needs inside the refrigerator.
[0021] In summary, this application has the following beneficial effects: 1. The cable outlet slot in the cable outlet housing allows the cable harness to pass through, and together with the mounting part, it facilitates installation with the refrigerator, realizes the orderly organization of the cable harness, reduces the problem of cable harness tangling and pulling, and ensures the normal operation of the components; 2. The annular groove on the outer peripheral wall of the wire inlet end of the housing is wrapped with tape to wrap the wire harness. The first sealing ring wrapped around the wire inlet end is squeezed by the tape, and the sealing element is set near the surface of the wire outlet end of the limiting ring, which improves the sealing and waterproof effect of the wire outlet housing and meets the high sealing and waterproof requirements of the refrigerator. 3. The anti-detachment component inside the housing prevents the wiring harness from detaching from the housing, ensuring the stability of the wiring harness connection and contributing to the stable operation of the refrigerator.

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.
[0025] This application discloses a sealed and waterproof cable outlet shell structure.
[0026] Example 1: A sealed and waterproof cable outlet shell structure, as shown in the reference. Figure 1 , Figure 2 The device includes a housing 1, wherein a cable outlet groove 11 is provided along the axis of the housing 1 for the cable harness 2 to pass through, and the two ends of the housing 1 are the cable inlet 12 and the cable outlet 13, respectively. In this embodiment, the cross-section of the housing 1 is waist-shaped, and the two sides of the housing 1 are rounded. The housing 1 is made of plastic material, which has a certain strength and corrosion resistance.
[0027] The housing 1 has a mounting part 3 near the outlet end 13 for installation with a refrigerator. A deformation groove 14 is provided on the outer peripheral wall of the housing 1 near the outlet end 13, extending to the inner peripheral wall of the housing 1 and the end face of the outlet end 13. Two deformation grooves 14 are provided and symmetrically arranged along the length of the housing 1. The mounting part 3 specifically includes a mounting strip 31 fixedly connected to the inner wall of the deformation groove 14 and a buckle 32 fixedly connected to the free end of the mounting strip 31. The thickness of the buckle 32 is greater than the thickness of the mounting strip 31, and the upper end of the buckle 32 protrudes from the outlet end 13 of the housing 1. Guide surfaces 321 are provided on the surfaces of the two buckles 32 that are far apart from each other. The guide surfaces 321 are inclined, and the cross-section of the buckles 32 gradually increases along its length towards the housing 1. In this embodiment, the mounting part 3 is integrally formed with the housing 1.
[0028] It should be noted that the refrigerator has a pre-drilled mounting groove for the housing 1. When the buckle 32 abuts against the two opposite inner walls of the mounting groove, it is pushed along the guide surface 321 to squeeze the buckle 32 so that it can pass through the mounting groove. When it is disengaged from the guide surface 321, the buckle 32's own elastic deformation is used to reset it, thereby limiting its sliding and disengagement from the mounting groove so that it can be installed on the refrigerator.
[0029] The outer peripheral wall of the housing 1 has an annular groove 4. Adhesive tape 5 is wrapped around the outer peripheral wall of the housing 1 outside the annular groove 4. The adhesive tape 5 is used to wrap several wire bundles 2. A limiting ring 15 is coaxially sleeved on the outer peripheral wall of the housing 1. In this embodiment, the limiting ring 15 is fixedly connected to the housing 1. The limiting ring 15 can be integrally formed with the housing 1. The diameter of the limiting ring 15 is larger than the diameter of the housing 1, so as to limit the adhesive tape 5 wrapped on the housing 1.
[0030] The implementation principle of the sealed and waterproof cable outlet shell structure in this application embodiment is as follows: the annular groove 4 on the outer peripheral wall of the cable inlet end 12 of the shell 1 is wrapped with tape 5 to wrap the cable harness 2, the first sealing ring 16 wrapped around the cable inlet end 12 is squeezed by the tape 5, and the sealing element 6 is provided near the surface of the cable outlet end 13 of the limiting ring 15, which improves the sealing and waterproof effect of the cable outlet shell and meets the high sealing and waterproof requirements of the refrigerator.
[0031] Example 2: Reference Figure 3 , Figure 4 The difference from Embodiment 1 is that the housing 1 is provided with a first sealing ring 16 around the inlet end 12, and the tape 5 is wrapped around the first sealing ring 16 to compress the first sealing ring 16, so as to enhance the sealing between the inlet end 12 of the outlet housing and the wire harness 2.
[0032] In this embodiment, the annular groove 4 is provided in a stepped groove shape, including a first groove 41 and a second groove 42 with different groove depths. The groove wall of the first groove 41 near the outlet end 13 has a 30°-60° inclined structure, thereby reducing the detachment of the tape 5.
[0033] Example 3: Reference Figure 5 The difference from Embodiment 1 is that a sealing element 6 is provided on the surface of the limiting ring 15 near the outlet end 13. The sealing element 6 is specifically a second sealing ring fixedly connected to the limiting ring 15. By squeezing the second sealing ring during the installation of the housing 1 in the refrigerator, the sealing effect at the installation groove is improved.
[0034] In this embodiment, an anti-detachment component 7 is provided inside the housing 1. The anti-detachment component 7 restricts the wire harness 2 from detaching from the housing 1, thereby effectively organizing the wire harness 2 inside the refrigerator and improving the sealing and waterproofing effect at the wire outlet. Specifically, the anti-detachment component 7 includes a limiting piece fixedly connected inside the housing 1. The limiting piece can be integrally formed with the housing 1. Several limiting pieces are spaced apart along the axis of the housing 1. A first anti-slip texture 17 is formed on the inner peripheral wall of the housing 1 between two adjacent limiting pieces. The free end of the limiting piece away from the housing 1 is inclined towards the direction close to the wire outlet 13. Several sets of limiting pieces are arranged along the length direction of the housing 1. Adjacent sets of limiting pieces are staggered, and a second anti-slip texture 71 is provided on the surface of the limiting piece near the wire harness 2.
[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
