[0023] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0024] Please see Figures 1 to 9 The first embodiment of this application provides a wire harness sleeve 100.

[0025] Please refer to Figure 8 and Figure 9 The wire harness sleeve 100 includes a sleeve body 10. The sleeve body 10 has a mounting hole 11 along the length direction X. The side wall of the sleeve body 10 has at least one notch 12. The notch 12 extends along the length direction X of the sleeve body 10 and is connected to the mounting hole 11. The notch 12 is used for the wire harness 30 to be inserted into the mounting hole 11. The outer wall of the sleeve body 10 has at least one slot 13.

[0026] The aforementioned wire harness sleeve 100, by having a notch 12 on the sleeve body 10, allows the wire harness 30 to be quickly inserted into the mounting hole 11 when it is installed, thus improving installation efficiency. At the same time, by having a slot 13 on the outer wall of the sleeve body 10, the slot 13 can cooperate with the external structure, so that the sleeve body 10 can drive the wire harness 30 to be inserted into the external structure, thus fixing the wire harness 30 on the external structure.

[0027] Understandably, to accommodate different numbers of wire harnesses 30, the main body 10 can be provided with multiple notches 12 and multiple mounting holes 11, with one mounting hole 11 and one notch 12 corresponding to each other and connected. One mounting hole 11 can accommodate one wire harness 30, thereby achieving the fixed installation of multiple wire harnesses 30.

[0028] It should be noted that the wire harness sleeve 100 in this embodiment is a plastic sleeve that can deform under the pressure of external force, and the width of the notch 12 needs to be set to be smaller than the radial dimension of the wire harness 30. After the wire harness 30 is inserted into the mounting hole 11, the wire harness 30 can be restricted by the hole wall of the mounting hole 11 to prevent it from coming out of the notch 12.

[0029] The radial dimension of the wire harness 30 is approximately 0.6 mm. When setting the size of the notch 12, the width of the notch 12 along the length direction X perpendicular to the sleeve body 10 is in the range of 0.2-0.4 mm. That is, the width of the notch 12 is smaller than the radial dimension of the wire harness 30. Thus, by setting the size of the notch 12, when the wire harness 30 is inserted into the mounting hole 11 through the notch 12, the sleeve body 10 is squeezed and deformed by the wire harness 30 with a larger radial dimension. After being inserted into the mounting hole 11, the sleeve body 10 returns to its original shape under its own elasticity, thereby constraining the wire harness 30 within the sleeve body 10.

[0030] In some embodiments, the width of the notch 12 can be set to a value such as 0.2mm, 0.3mm or 0.4mm, depending on the radial size of the wire harness 30, and is not limited thereto.

[0031] Furthermore, in order to ensure the stability of the wire harness sleeve 100 when installed on the external structure, the slot 13 is arranged around the circumference of the sleeve body 10. That is, the shell 21 of the external structure is locked around the sleeve body 10 in all directions to limit the sleeve body 10 and prevent the sleeve body 10 from detaching from the shell 21.

[0032] Specifically, the sleeve body 10 of this embodiment includes two clamping portions 14 disposed opposite to each other and a connecting portion 15 connected between the two clamping portions 14. The distance between the two clamping portions 14 forms a slot 13. The clamping portions 14 protrude from the connecting portion 15 in the circumferential direction, so that a slot 13 arranged in the circumferential direction is formed on the sleeve body 10.

[0033] Further, please refer to Figure 9 Since the housing 21 needs to be fitted into the slot 13, in order to improve the installation efficiency between the sleeve body 10 and the housing 21, the outer edge of the side wall of the slot 13 is provided with a first chamfer 16. In this way, the outer edge of the side wall of the slot 13 is smoothly transitioned by the first chamfer 16, which not only guides the insertion of the housing 21, but also prevents scratches to the housing 21 during installation. Specifically, the outer edges of the two clamping parts 14 facing each other are provided with a first chamfer 16.

[0034] Furthermore, a second chamfer 17 is provided at the contact point between the side wall and the bottom wall of the slot 13. Specifically, a second chamfer 17 is provided at the connection point between the clamping part 14 and the connecting part 15. In this way, when the housing 21 is inserted into the slot 13, it can be quickly inserted into place along the second chamfer 17, so as to achieve a guiding function through the second chamfer 17.

[0035] The aforementioned wire harness sleeve 100, by setting the slot 13 to be arranged circumferentially along the sleeve body 10, when the wire harness sleeve 100 is installed on the external structure, the external structure is inserted into the circumference of the sleeve body 10, and the external structure can limit the wire harness sleeve 100 in multiple directions to prevent the wire harness sleeve 100 from coming off relative to the housing 21; by setting the width of the notch 12 to be less than the radial dimension of the wire harness 30, the wire harness sleeve 100 can be squeezed and deformed by the wire harness 30 and then inserted into the mounting hole 11, and the sleeve body 10 can restore its original shape by its own elastic properties and then restrict the wire harness 30 in the mounting hole 11, so that the sleeve body 10 achieves the limiting installation of the wire harness 30.

[0036] Please see Figures 1 to 7 In another embodiment, the present invention also provides an electrical system 200, including a control appliance 20 and the aforementioned wire harness sleeve 100.

[0037] The control electrical appliance 20 includes a housing 21 and a main structure 22 disposed within the housing 21. The housing 21 is provided with a locking hole 214. The wire harness 30 is connected to the main structure 22. In the wire harness sleeve 100, the wire harness sleeve 100 is locked in the locking hole 214, and the housing 21 is embedded in the locking groove 13. The wire harness 30 passes through the wire harness sleeve 100.

[0038] In the aforementioned electrical system 200, since the wire harness sleeve 100 for installing the wire harness 30 has a notch 12, the wire harness 30 can be inserted into the mounting hole 11 through the notch 12 during installation, improving the installation efficiency of the wire harness 30. At the same time, when the wire harness sleeve 100 is installed on the control electrical appliance 20, a locking hole 214 is provided on the housing 21 so that the wire harness sleeve 100 is locked in the locking hole 214, and the housing 21 is embedded in the locking groove 13 of the wire harness sleeve 100. The housing 21 limits the wire harness sleeve 100 and prevents the wire harness sleeve 100 from coming off relative to the housing 21, thereby ensuring the stability of the installation position of the wire harness 30.

[0039] Specifically, when the housing 12 is provided with a locking hole 214, the housing 21 can be a complete structure, and the locking hole 214 is opened on one side wall of the housing 21. First, the wire harness 30 is inserted into the wire harness sleeve 100, and then the wire harness sleeve 100 is inserted into the locking hole 214 in a way that causes deformation under external force.

[0040] Further, please refer to Figure 1 and Figure 2 To facilitate the assembly of the entire electrical system 200, the housing 21 in this embodiment includes a lower housing 211 and an upper cover 212. The lower housing 211 has a first sub-hole 2141, and the upper cover 212 has a second sub-hole 2142. The first sub-hole 2141 and the second sub-hole 2142 form a locking hole 214. A locking groove 13 is arranged circumferentially along the main body 10. Both the lower housing 211 and the upper cover 212 are locked in the locking groove 13. Thus, by setting the housing 21 to include two parts, the assembly of the entire electrical system 200 is facilitated. In assembling the device system 200, after inserting the wire harness 30 into the wire harness sleeve 100, the wire harness sleeve 100 is then secured to the first sub-hole 2141. Next, the upper cover 212 is placed on the lower shell 211, and the upper cover 212 is simultaneously secured into the slot 13. At this point, the main body of the sleeve is also secured into the second sub-hole 2142. Thus, the upper cover 212 and the lower shell 211 are secured around the slot 13, which can limit the movement of the wire harness sleeve 100 in all directions and prevent it from moving relative to the shell 21.

[0041] Please refer to Figures 3 to 5 When the upper cover 212 and the lower shell 211 are engaged in the slot 13, the upper cover 212 and the lower shell 211 are stacked along the length X of the wire harness sleeve 100 within the slot 13. Thus, the two have a certain overlapping area along the length X of the wire harness sleeve 100, and are pressed into the slot 13 of the wire harness sleeve 100, ensuring a tight fit between the lower shell 211 and the upper cover 212, preventing loosening. Simultaneously, the overlapping area also achieves a sealing effect, preventing water from flowing into the internal space formed by the upper cover 212 and the lower shell 211. In other embodiments, the upper cover 212 and the lower shell 211 can also be overlapped along the closing direction of the upper cover 212 and the lower shell 211 to achieve the effect of being secured by the slot 13.

[0042] Further, please refer to Figure 5 and Figure 9 To ensure the installation stability of the upper cover 212 and lower shell 211 on the wire harness sleeve 100, the width a of the slot 13 along the length X of the sleeve body 10 is greater than the total thickness b of the upper cover 212 and lower shell 211 when they are engaged in the slot 13. Thus, when the upper cover 212 and lower shell 211 are engaged in the slot 13, they pressurize and deform the groove wall of the slot 13, forming an interference fit along the length X of the wire harness sleeve 100, ensuring the installation stability of the wire harness sleeve 100 and preventing shaking during use. At the same time, the groove wall of the slot 13 can clamp the upper cover 212 and lower shell 211 in the slot 13, achieving a fastening effect and reducing the use of fasteners between the upper cover 212 and lower shell 211.

[0043] Specifically, the difference between b and a is: 0.1mm≤ab≤0.2mm. This avoids affecting the interference fit between the two when the difference is set too large, and also avoids making it difficult to install the upper cover 212 and the lower shell 211 into the slot 13 when the difference is set too small.

[0044] In some embodiments, the difference between a and b can be a value such as 0.1 mm, 0.15 mm, or 0.2 mm, and is not limited thereto.

[0045] Further, please refer to Figure 6 and Figure 7 When the upper cover 212 and the lower shell 211 are stacked and installed, the edge of at least one of the upper cover 212 and the lower shell 211 is thinned. That is, one of the upper cover 212 or the lower shell 211 is provided with a stepped surface 213, and the other overlaps on the stepped surface 213. In this way, the two have a mutual support effect, ensuring the appearance consistency of the shell 21 during installation.

[0046] Specifically, in this embodiment, when setting the stepped surface 213, the lower shell 211 is thinned at its end edge, so that the lower shell 211 has a stepped surface 213, and the entire shell overlaps on the stepped surface 213, with the lower shell 211 supporting the upper cover 212.

[0047] In this embodiment, the control electrical appliance 20 can be a contactor or a relay. When the control electrical appliance is a relay, the main structure 22 includes a coil module and a contact module. The current in the coil module is switched on or off to control the closing or opening of the contact module, thereby realizing the on / off control of the external circuit.

[0048] The aforementioned electrical system 200, by configuring the housing 21 to include a lower housing 211 and an upper cover 212, facilitates the installation of the wire harness sleeve 100 and the wire harness 30 into the slot 214; by setting the width a of the slot 13 along the length X of the sleeve body 10 to be greater than the total thickness b of the upper cover 212 and the lower housing 211 being installed in the slot 13, the housing 21 and the wire harness sleeve 100 can be installed in an interference fit manner, ensuring the installation stability of the wire harness sleeve 100 and preventing shaking.

[0049] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
