[0037] like Figures 1 to 5 As shown, the first aspect of the utility model proposes a wire passing member 20, at least a part of which is used to be snapped into the wire outlet hole 12 of the box body 10, and the wire passing member 20 is provided with a wire passing channel 200, and the wire passing channel 200 is used for allowing the wire group in the box body 10 to pass through, and the wire passing channel 200 includes a first wire passing hole group and a second wire passing hole 221 connected in sequence, the first wire passing hole group includes a plurality of first wire passing holes 211, and the second wire passing hole 221 is connected to the plurality of first wire passing holes 211.

[0038] It can be understood that the box body 10 can be the outer shell of the electric control box assembly. The box body 10 can be a cubic box structure, which is formed by buckling an upper cover and a lower shell. A receiving cavity 11 is formed between the upper cover and the lower shell. The receiving cavity 11 is used to install the electronic components of the electric control box assembly. A wire outlet hole 12 can be provided on the side wall of the lower shell to lead the wire harness 30 of the electronic component out of the box body 10. The wire passing member 20 can be a cylindrical structure. The wire passing channel 200 is defined inside the wire passing member 20. The wire passing hole connects the receiving cavity 11 and the outside. The wire passing member 20 is connected to the wire outlet hole 12, so that the wire outlet hole 12 is sealed and the installation is more convenient. The wire passing channel 200 is arranged along the axial direction of the wire outlet hole 12, and the wire passing channel 200 includes a first wire passing hole group composed of multiple first wire passing holes 211 and a separately arranged second wire passing hole 221. The first wire passing hole 211 is used for the wire bundle of the wire group 30 to pass through, and the second wire passing hole 221 can be arranged at one axial end of the first wire passing hole 211, or a second wire passing hole 221 is arranged at both axial ends of the first wire passing hole 211. The second wire passing hole 221 is used to fix the wire group 30 before the wire group 30 is divided into multiple wire bundles, and to gather and fix the wire group 30 after the wire group 30 appears. The multiple first wire passing holes 311 can be arranged in an array along the radial direction of the wire outlet hole 12, such as a circular array, to adapt to the wire group 30 designed as a cylindrical cable structure.

[0039] The utility model installs a wire passing piece in the wire outlet hole of the box body. The wire passing piece 20 has a wire passing channel 200 for the wire group 30 in the box body 10 to pass through. The wire passing channel 200 has a plurality of first wire passing holes 211. The wire group 30 can be designed at the wire outlet position to be a multi-wire harness structure imitating a cable. Each wire harness is fixed in the corresponding first wire passing hole 211 and passes out of the box body 10. As a result, the deformation stress of the wire group 30 at the wire outlet position is small, the structure is stable and not easy to bounce, and the installation of the wire group 30 at the wire outlet position is convenient.

[0040] In some embodiments of the utility model, the wire passing member 20 includes a first wire passing sleeve 21 and a second wire passing sleeve 22. At least a portion of the first wire passing sleeve 21 is interference-fitted in the wire outlet hole 12. The first wire passing sleeve 21 is provided with a plurality of first wire passing holes 211. The second wire passing sleeve 22 is connected to one end of the first wire passing sleeve 21 in the axial direction. The second wire passing sleeve 22 is provided with a second wire passing hole 221. The diameter value of the second wire passing sleeve 22 is smaller than the diameter value of the first wire passing sleeve 21.

[0041] It can be understood that the first wire sleeve 21 is a porous structure, and the first wire sleeve 21 defines a plurality of first wire holes 211, so that a plurality of wire harnesses 30 can be arranged in a one-to-one correspondence through the plurality of first wire holes 211, and the hole wall of the first wire hole 211 limits the wire harness 30, improves the connection reliability of the wire harness 30, and makes the wire harness group not easy to twist and bend in the first wire sleeve 21, and has good structural stability. The shape of the first wire hole 211 can be adapted to the wire harness 30, for example, a circular hole, and the diameter is close, so that the gap after the wire harness 30 is arranged in the first wire hole 211 is small, and the sealing is good. The length of the first wire sleeve 21 can be greater than the outlet hole 12, so that part of the first wire sleeve 21 is installed in the outlet hole 12 by interference, so as to achieve sealing. The plurality of first wire holes 211 can be arranged in a circular array or a rectangular array, and the axial direction of the first wire hole 211 is the same as the axial direction of the outlet hole 12, so that the wire harness 30 is threaded more smoothly. It can be understood that the second wire passing sleeve 22 is a single-hole section, so that the multiple wire harnesses 30 passing through the multiple first wire passing holes 211 are gathered in the second wire passing hole 221 to facilitate further wiring.

[0042] In some embodiments of the present invention, at least a portion of the first wire sleeve 21 is in interference connection with the wire outlet hole 12 .

[0043] It can be understood that by interference fitting the first wire sleeve 21 of the wire-passing member 20 in the wire outlet hole 12 of the electric control box assembly, the position between the wire group of the electric control box assembly and the wire outlet hole 12 is sealed, and the first wire sleeve 21 is interference fit with the wire outlet hole 12, with good sealing effect and low implementation cost, which makes it difficult for external dust and liquid to enter the interior of the electric control box assembly, thereby improving the reliability of the electric control box assembly.

[0044] In some embodiments of the present invention, the number of the second wire passing sleeves 22 is two, and one second wire passing sleeve 22 is respectively provided at both ends of the first wire passing sleeve 21 in the axial direction.

[0045] It can be understood that a second wire sleeve 22 can be provided at each end of the first wire sleeve 21 in the axial direction, so that the wire harness group first passes through the wire passing piece 20 from the second wire sleeve 22 located in the accommodating cavity 11, and then disperses to multiple first wire holes 211 to achieve fixation, and then gathers to another second wire sleeve 22 located outside the box body 10 to connect with other wiring.

[0046] In some embodiments of the present invention, the plurality of first wire passing holes 211 are distributed in a circular array along the circumferential direction of the wire outlet hole 12 .

[0047] It is understandable that three first wire holes 211 can be provided and distributed in a circumferential array, so that the wire group can be designed to imitate the cable structure, that is, the radial cross-section of the wire group is circular, and the multiple wire bundles of the wire group are arranged in a circumferential array. In addition, the first wire holes 211 are arranged neatly, which is convenient for production and threading.

[0048] In some embodiments of the present invention, the diameter of the second wire passing hole 221 is smaller than the diameter of the circumscribed circle of the plurality of first wire passing holes 211 .

[0049] It can be understood that after the multiple first wire passing holes 211 are distributed in a circular array, the diameter of the circumscribed circle of the multiple first wire passing holes 211 is larger than the diameter of the second wire passing holes 221, so that the wiring harness group is in a gathered posture in the second wire passing holes 221 relative to the first wire passing holes 211, and the deformation stress of the wiring harness group is small. After the wiring harness group is placed, the deformation of the wiring harness group is small and the posture is stable, and it is not easy to bounce up, making the installation simpler and worry-free.

[0050] In some embodiments of the present invention, the axial direction of the first wire passing hole 211 and / or the axial direction of the second wire passing hole 221 is parallel to the axial direction of the wire outlet hole 12 .

[0051] It can be understood that the first wire hole 211 and the second wire hole 221 can be parallel to the axial direction of the wire outlet hole 12, and the second wire sleeve 22 can be coaxially arranged with the first wire sleeve 21 to make threading smoother. The wire passing piece 20 plays a role in fixing and protecting the wire harness assembly.

[0052] In some embodiments of the present invention, the first wire passing hole 211 and / or the second wire passing hole 221 are / is a circular hole.

[0053] It can be understood that the first wire passing hole 211 and the second wire passing hole 221 can be adapted to the shape of the wiring harness 30. For example, when the wiring harness 30 is a cylindrical cable-like structure, the first wire passing hole 211 and the second wire passing hole 221 can be set as circular holes to fit the outer surface of the wiring harness 30, thereby improving the reliability of the connection between the wire passing piece 20 and the wiring harness 30, reducing the assembly gap, and improving the sealing.

[0054] In some embodiments of the present invention, the wire-passing member 20 is an elastic member.

[0055] It is understandable that the wire passing member 20 can be an integrally molded structure of rubber or silicone, so that it has elasticity and is convenient for interference installation in the wire outlet hole 12 to achieve a secure installation and good sealing effect.

[0056] In some embodiments of the present invention, the box body 10 is provided with a plurality of wire outlet holes 12 , and the number of the wire passing members 20 is plural, and a wire passing member 20 is interference-fitted in each wire outlet hole 12 .

[0057] It is understandable that a plurality of outlet holes 12 can be arranged at intervals on the side wall of the lower shell for different wire groups to pass through. In addition, the diameters of adjacent wire groups can be set to be consistent, and the same wire passing member 20 is used for outlet, thereby reducing the difference in parts and achieving a foolproof effect.

[0058] The second aspect of the utility model provides an electric control box assembly, including a box body and the wire passing member provided in the first aspect of the utility model, the box body has a wire outlet hole 12, and the wire passing member 20 is clamped in the wire outlet hole 12.

[0059] The electric control box assembly provided in the second aspect of the present invention has the same beneficial effects as the wire passing member provided in the first aspect of the present invention. The electric control box assembly can be applied to HVAC equipment, such as air conditioners or heat pumps.

[0060] In some embodiments of the present invention, the electric control box assembly further includes at least one wire group 30, the radial cross-section of the wire group 30 is circular, a portion of the wire group 30 is located in the accommodating cavity 11, and the wire group 30 includes a plurality of wire harnesses, which are sequentially passed through the first wire hole 211 and the second wire hole 221.

[0061] It can be understood that the wire group can be set to a cable-like structure through the wire passing piece 20 of the utility model, that is, a structure with a circular radial cross-section and containing multiple wire harnesses extending in parallel. The wire harnesses are passed through the corresponding first wire passing holes 211, so that the deformation stress of the wire group 30 at the wire outlet hole 12 is reduced, which facilitates the installation of the outlet wire and is not easy to bounce.

[0062] The above are only preferred specific implementations of the utility model, but the protection scope of the utility model is not limited thereto.
