Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a wire harness fixing device in an electrical equipment and the electrical equipment. Background Art

[0002] At present, for some electrical equipment on the market, there is a problem of arranging a large number of wire harnesses in a small space. In order to ensure the safety of the equipment, these wire harnesses need to be reasonably fixed and sealed. Taking a household refrigerator as an example, generally, a foamed insulating material is filled in the insulating space between the cabinet shell and the inner liner. At the same time, the main wire harness of the refrigerator generally also passes through the cabinet shell, and through the insulating space, the refrigerator main control board outside the cabinet shell is connected to various electrical components inside the cabinet to realize the power supply and control of each electrical component. In order to prevent the foamed insulating material inside the cabinet shell from overflowing, the wire harness needs to be fixed and sealed with tape near the wire passing hole on the cabinet shell. In this case, the fixing of the wire harness is unstable and not conducive to management and control, and simply using tape to seal the wire harness may cause a long sealing area and there is a problem of insufficient space.

Specific embodiments

[0035] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0036] Such as Figure 1 And Figure 2As shown in the figure, this embodiment provides a wire harness fixing device 30 in an electrical device. The electrical device includes a box housing 10 and a wire harness 20. A wire passing hole is further provided on a preset surface 11 of the box housing 10. The function of the wire passing hole is to allow the wire harness 20 to pass through. Generally, there are many wire harnesses 20 in the electrical device. These wire harnesses 20 pass through the wire passing holes on the preset surface 11 of the box housing 10 to connect the controller outside the box housing 10 and various electrical components inside the box housing, realizing the power supply and control of the electrical components. It should be noted that the preset surface 11 of the box housing 10 can be any surface of the box housing 10 as long as there is a wire passing hole for the wire harness 20 to pass through on this surface, and it can be used as the above-mentioned preset surface 11.

[0037] Combined with Figure 3 and Figure 4 As shown in the figure, a wire harness fixing device 30 is further provided on the box housing 10 of the electrical device. The wire harness fixing device 30 is specifically arranged at the position of the wire passing hole on the preset surface 11. The wire harness fixing device 30 mainly includes a wire harness embedding box 31, a box housing plug-in 32 and a sealing member (not shown in the figure).

[0038] The inside of the wire harness embedding box 31 includes a first wire passing channel 311 and a second wire passing channel 312. The overall outer shape structures of the first wire passing channel 311 and the second wire passing channel 312 are both in a shape similar to a cylinder. Both the first wire passing channel 311 and the second wire passing channel 312 have an inlet end and an outlet end. Among them, the outlet end of the first wire passing channel 311 is communicated with the inlet end of the second wire passing channel 312 to realize the communication between the first wire passing channel 311 and the second wire passing channel 312, so that the wire harness 20 passes through the first wire passing channel 311 and the second wire passing channel 312 in sequence.

[0039] The box housing plug-in 32 passes through the wire passing hole on the preset surface 11 of the box housing 10 and is snap-fitted and fixed on the preset surface 11. Four first hooks 3112 are provided at the inlet end of the first wire passing channel 311 of the wire harness embedding box 31. After the first wire passing channel 311 passes through the box housing plug-in 32, these first hooks 3112 are snap-fitted at the end of the box housing plug-in 32 to realize that the first wire passing channel 311 passes through the wire passing hole on the preset surface 11 and is fixedly connected to the preset surface 11. The second wire passing channel 312 of the wire harness embedding box 31 is arranged inside the box housing 10, and the extending direction of the second wire passing channel 312 is arranged parallel to the preset surface 11. When the wire harness 20 passes through the first wire passing channel 311 and the second wire passing channel 312 in sequence, the sealing member is connected to the wire harness 20 located in the second wire passing channel 312 and is fixedly arranged at the position of the outlet end of the second wire passing channel 312. Among them, the sealing member can simply use tape to connect to the wire harness 20 and seal the outlet end, or the sealing member can also use sealant to connect the wire harness 20 and seal the outlet end by filling the sealant.

[0040] With the above settings, the wire harness fixing device 30 can pass through the wire passing hole on the preset surface 11 of the box shell 10 by means of the first wire passing channel 311 of the wire harness embedded box 31, and be fixedly connected to the preset surface 11, ensuring that the wire harness embedded box 31 is relatively fixed to the box shell 10 at the position of the wire passing hole. Then, through the position setting of the second wire passing channel 312 inside the box shell 10 and the preset surface 11, when the wire harness 20 passes through the second wire passing channel 312, it can extend along the preset surface 11. Finally, through the setting of the sealing member, the fixing of the wire harness 20 and the sealing of the wire harness embedded box 31 are realized, preventing substances such as foaming materials inside the box shell 10 from flowing to the outside. Compared with directly fixing and sealing the wire harness 20 with tape and sponge in the prior art, on the one hand, this setting can enable the wire harness 20 to be routed and fixed reasonably through the wire harness embedded box 31, preventing the problems of the wire harness 20 being messy and the wire outlet length being unstable due to insufficient space. On the other hand, only a sealing member needs to be set at the outlet end of the second wire passing channel 312 for sealing, preventing the problem of a relatively long sealing area that may occur when using tape and sponge for sealing due to insufficient space.

[0041] It should be noted that in this embodiment, the wire harness embedded box 31 is fixedly arranged relative to the box shell 10 through the box shell plug-in 32, that is, first pass the box shell plug-in 32 through the wire passing hole and snap-fix it on the preset surface 11, then pass the first wire passing channel 311 through the box shell plug-in 32, and then use the first hook 3112 arranged at the inlet end of the first wire passing channel 311 to snap onto the end of the box shell plug-in 32. Through this double-passing and fixing method, the wire harness embedded box 31 can be more stable at the wire passing hole position of the box shell 10, avoiding the loosening of the wire harness embedded box 31 caused by long-term use. However, in other alternative embodiments, the wire harness embedded box 31 may not be fixed relative to the box shell 10 by using the box shell plug-in 32. For example, directly adjust the structural form of the first hook 3112 and make it directly arranged on the periphery of the first wire passing channel 311, so that after the first wire passing channel 311 directly passes through the wire passing hole, these first hooks 3112 are used to fix it relative to the box shell 10.

[0042] Such as Figure 3 and Figure 4As shown, in the wire harness embedded box 31, the first wire passing channel 311 and the second wire passing channel 312 are arranged perpendicular to each other. The wire harness embedded box 31 vertically penetrates through the wire passing hole on the preset surface 11 by using the first wire passing channel 311, and the second wire passing channel 312 is parallel and abuts against the preset surface 11 inside the box shell 10. Through this kind of structure and position setting, the cooperation between the first wire passing channel 311 and the wire passing hole can be made more stable. At the same time, the second wire passing channel 312 is parallel and abuts against the preset surface 11 inside the box shell 10, that is, the included angle between the extending direction of the second wire passing channel 312 and the preset surface 11 is 0 degrees, so that the wire harness 20 can extend and be fixed by fitting the preset surface 11. When the internal space of the box shell 10 is insufficient at the position of the preset surface 11, more wire harnesses 20 can be arranged more effectively without causing chaos. However, in other alternative embodiments, the extending direction of the second wire passing channel 312 and the preset surface 11 may not be parallel, and in actual operation, it only needs to meet within a certain angle range. A preferable setting is that the included angle between the extending direction of the second wire passing channel 312 and the preset surface 11 is less than or equal to 20 degrees.

[0043] As Figure 3 and Figure 4 shown, in this embodiment, the second wire passing channel 312 of the wire harness embedded box 31 includes two outlet ends, which are respectively arranged at both ends in the axial direction of the second wire passing channel 312. The first wire passing channel 311 is vertically connected to the middle part in the axial direction of the second wire passing channel 312, and the first wire passing channel 311 and the second wire passing channel 312 form a T-shaped structure. By setting the second wire passing channel 312 to include two outlet ends, after the wire harness 20 enters the inlet end of the second wire passing channel 312 through the outlet section of the first wire passing channel 311, it can be led out in the second wire passing channel 312 towards the two outlet ends arranged in opposite directions, so as to be more flexibly connected to the electrical components at the corresponding positions, and at the same time, it can also be applicable to more types of wire harnesses 20, improving the applicable range of the wire harness fixing device 30. For example, this kind of structure setting can be more suitable for the installation of a one-to-two wire harness. In other alternative embodiments, the number of outlet ends of the second wire passing channel 312 can also be set to other numbers, without a fixed limit. In addition, in this embodiment, the first wire passing channel 311 is connected to the middle part in the axial direction of the second wire passing channel 312. In other alternative embodiments, it can also be connected to other parts in the axial direction of the second wire passing channel 312, as long as the first wire passing channel 311 and the second wire passing channel 312 can form a T-shaped structure.

[0044] In addition, as Figure 4As shown, a sealing cover 3122 is further provided at the outlet end of the second wire passing channel 312 of the wire harness embedded box 31. The sealing cover 3122 can be directly fitted with the outlet end to open or close the corresponding outlet end. When wire harnesses 20 do not need to be arranged at some outlet ends in the second wire passing channel 312, the sealing cover 3122 can be directly used to seal the outlet end, making the use of the wire harness embedded box 31 more flexible.

[0045] As Figure 5 and Figure 6 shown in FIGS. and, the first wire passing channel 311 in the wire harness embedded box 31 specifically includes two first wire passing grooves 3111 with symmetric structures. The second wire passing channel 312 includes two second wire passing grooves 3121 with symmetric structures. The two first wire passing grooves 3111 are respectively corresponding and communicated with the two second wire passing grooves 3121. Then, by clamping and fixing between the two first wire passing grooves 3111, or between the two second wire passing grooves 3121, or simultaneously between the two first wire passing grooves 3111 and the two second wire passing grooves 3121, with such a structure setting of the first wire passing channel 311 and the second wire passing channel 312, during manufacturing and assembly, the first wire passing grooves 3111 and the second wire passing grooves 3121 can be separately manufactured and processed, simplifying the manufacturing process and technology. After manufacturing, each first wire passing groove 3111 and the second wire passing groove 3121 are respectively corresponding and communicated. At this time, directly clamping and fixing between the two first wire passing channels 311 and / or the two second wire passing grooves 3121 can achieve assembly, further improving the convenience of installation and disassembly.

[0046] In this embodiment, after the two first wire passing grooves 3111 and the two second wire passing grooves 3121 are respectively communicated, connecting parts 314 are respectively arranged on the periphery of the first wire passing grooves 3111. A second hook 3141 is arranged on one of the two connecting parts 314, and a clamping hole 3142 is arranged on the other. After the two second wire passing grooves 3121 are connected, then the second hook 3141 and the clamping hole 3142 on the two first wire passing grooves 3111 are fitted, finally forming a complete first wire passing groove 3111 and a second wire passing groove 3121, which are both simpler and more convenient in manufacturing and assembly. In other alternative embodiments, other existing methods in the prior art can also be used for clamping and fixing between the two first wire passing channels 311 and / or the two second wire passing channels 312.

[0047] As Figure 3 and Figure 4As shown, the wire harness embedded box 31 further includes a fixing portion 313 and a fastener. The fixing portion 313 is disposed on the outer surface of the first wire passing channel 311. The fixing portion 313 abuts against the preset surface 11. The fastener passes through the preset surface 11 and is fixedly connected within the fixing portion 313. By providing the fixing portion 313 on the outer surface of the first wire passing channel 311, when the wire harness embedded box 31 passes through the wire passing hole on the preset surface 11 by using the first wire passing channel 311, the second wire passing channel 312 can abut against the preset surface 11 of the box shell 10 by means of the fixing portion 313. Moreover, when the first wire passing channel 311 rotates within the wire passing hole, the connection range of the fastener can also be increased through the setting of the fixing portion 313, so that after the fastener passes through the preset surface 11, it can be effectively fixedly connected within the fixing portion 313, realizing the fixation between the wire harness embedded box 31 and the box shell 10. With this kind of setting, the area where the fixing portion 313 abuts against the preset surface can be used as the connection area of the fastener, so that when the embedded box rotates inside the box shell 10, the fastener can be used for connection and fixation. Among them, the fastener can adopt any element that can be passed through and fixed in the existing technology, such as a fastening screw.

[0048] It should be noted that in this embodiment, both the first wire passing channel 311 and the second wire passing channel 312 are arranged in a cylindrical structure, and the radial dimensions of the first wire passing channel 311 and the second wire passing channel 312 are equal, making the overall structure of the wire harness embedded box 31 more reasonable and more suitable for the passing and fixation of the wire harness 20. In other alternative embodiments, without affecting the above functions of the first wire passing channel 311 and the second wire passing channel 312, their specific structures and dimension settings can be adjusted accordingly, without fixed limitations.

[0049] As described above, in this embodiment, the wire harness embedded box 31 is fixedly arranged relative to the box shell 10 through the box shell plug-in 32. Combining Figure 7 and Figure 8As shown in the figure, the box housing plug 32 specifically includes a plugging cylinder 321 and a stepped portion 322. A buckle member 3211 is provided on the surrounding wall of the plugging cylinder 321. The stepped portion 322 is disposed around the outer periphery of the end of the plugging cylinder 321. The plugging cylinder 321 cooperates with the wire passing hole so that the plugging cylinder 321 is inserted through the wire passing hole. The stepped portion 322 and the buckle member 3211 respectively abut on both sides of the preset surface 11. In this case, the movement of the box housing plug 32 relative to the preset surface 11 in the axial direction of the plugging cylinder 321 can be restricted, and it can be prevented from detaching from the preset surface 11 of the box housing 10. The first wire passing channel 311 of the wire harness pre-buried box 31 passes through the plugging cylinder 321, and the second wire passing channel 312 abuts on the preset surface 11 through the stepped portion 322. The first hook 3112 at the inlet end position of the first wire passing channel 311 is clamped at the end of the plugging cylinder 321, realizing the fixation of the wire harness pre-buried box 31 relative to the box housing plug 32. The overall structure is more reasonable and the connection is convenient.

[0050] In addition, a sealing sponge (not shown in the figure) is sleeved on the outer periphery of the plugging cylinder 321. When the plugging cylinder 321 inserted into the box housing 10 passes through the wire passing hole and the stepped portion 322 abuts on the preset surface 11, the sealing sponge is located between the stepped portion 322 and the preset surface 11. Through the setting of the sealing sponge, the sealing performance of the box housing 10 at the position of the wire passing hole is further improved, and it is more effective to prevent the overflow of materials such as foamed insulation inside the box housing 10.

[0051] This embodiment also provides an electrical device, which includes a box housing 10, a wire harness 20 and the wire harness fixing device 30 as described above. A wire passing hole is provided on the preset surface 11 of the box housing 10. The wire harness fixing device 30 is fixed at the position of the wire passing hole. The wire harness 20 is inserted and fixed through the wire passing hole by the wire harness fixing device 30. By adopting the wire harness fixing device 30 as described above on the electrical device, it is possible to prevent the materials inside the box housing 10 of the electrical device from overflowing at the position of the wire passing hole, and it is possible to fix the wire harness 20 in the case of insufficient space. At the same time, the wire harness 20 can be protected to prevent the edge of the wire passing hole from being too sharp and damaging the wire harness 20. Specifically, the electrical device can be a refrigerator electrical appliance. The refrigerator electrical appliance includes a box housing 10 and an inner liner (not shown in the figure) provided inside the box housing 10. A foaming member is provided between the housing and the inner liner. The main function of the foaming member is to improve the heat insulation performance of the refrigerator device, prevent cold air from escaping, and thus maintain the stability of the internal temperature. A wire passing hole is provided on the preset surface 11 of the box housing 10 of the refrigerator electrical appliance. The wire harness fixing device 30 is fixed at the position of the wire passing hole. The wire harness 20 of the refrigerator electrical appliance is inserted and fixed through the wire passing hole by the wire harness fixing device 30 to connect the refrigerator main control board outside the box housing 10 and various electrical components inside the box housing 10.

[0052] It should be noted that in other alternative embodiments, the wire harness fixing device 30 can also be arranged on other electrical devices, as long as the electrical device is provided with a wire passing hole on the preset surface 11, the wire harness fixing device 30 can be arranged at the position of the wire passing hole to achieve the fixing and sealing of the wire harness 20.

[0053] The above is the preferred embodiment of the present invention, and the technical solution of the present invention has been further described in detail. It is not used to limit the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the present invention.
