Detailed Description of the Invention

[0030] Hereinafter, with reference to the accompanying drawings, the preferred embodiments of the present invention will be described in detail. In the following description, the same reference numerals are assigned to the same components, and repeated descriptions are omitted. In addition, the drawings are only schematic diagrams, and the proportional relationship of the dimensions between components or the shape of components may be different from the actual ones. It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0031] It should also be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0032] In order to ensure the stable transmission of electricity and signals, existing electrical equipment usually sets up a junction box at the wiring port, and components such as sealing rubber rings in the junction box play a role in waterproofing, dustproofing and other protections. However, these junction boxes are difficult to meet the requirements of different electrical equipment. For example, for the cluster-level control box of an energy storage container, it has many interfaces and complex wire harnesses, and the junction box adopted also needs to have multiple wire-passing holes to meet its requirements.

[0033] In view of the above technical problems in the prior art, with reference to Figures 1 to 6The first aspect of the present application provides a wire passing device, which includes a mounting box 1, a sealing member 2 and a cover body 3. The mounting box 1 includes a connecting portion 11 and a pressing portion 12 connected to each other along a first direction, and the mounting box 1 is provided with a through hole 13 penetrating the connecting portion 11 and the pressing portion 12 in the first direction, and the pressing portion 12 is provided with a plurality of deformation grooves 14; the sealing member 2 is accommodated in the through hole 13, and the sealing member 2 is provided with a wire passing hole 21, and the wire passing hole 21 is used for passing an external wire harness; the cover body is detachably connected to the connecting portion 11, and when the cover body 3 is connected to the connecting portion 11, the cover body 3 is sleeved on the pressing portion 12 and drives the pressing portion 12 to deform, so that the pressing portion 12 presses the sealing member 2.

[0034] According to the above structure, the wire-passing device provided in the present application can remove the seal 2 from the through hole 13, so that by replacing the seals 2 with different numbers of wire-passing holes 21 or different sizes of wire-passing holes 21, it is widely applicable to a variety of electrical equipment, and different seals 2 can be flexibly replaced according to selection. When the seal 2 needs to be replaced, the cover body 3 and the installation box 1 are disassembled, and the new seal 2 is replaced, which is easy to operate. And the cost of replacing a single seal 2 is significantly lower than replacing the entire wire-passing device, which helps users reduce the cost of use. In addition, when the cover body 3 is connected to the connecting part 11, the pressing part 12 can press the seal 2, thereby constraining the seal 2, and the sealing effect is better. It can also prevent the seal 2 from being separated from the preset position, and avoid its rotation and the entanglement of multiple wire harnesses.

[0035] Specifically, when the wire-passing device is in use, the side of the connecting portion 11 facing away from the clamping portion 12 is used to be installed on the external wiring board 100. The user needs to pass the external wire harness through the wire-passing hole 21 of the seal 2 and place the seal 2 in the through hole 13. Then the cover 3 is sleeved on the clamping portion 12 of the installation box 1 and connected to the clamping portion 12. When the cover 3 is connected to the clamping portion 12, the cover 3 can drive the clamping portion 12 to deform so that the clamping portion 12 clamps the seal 2. The principle of the clamping portion 12 clamping the seal 2 can be referred to. Figures 1 to 3 , and reference Figure 7 . After the cover body 3 is connected to the pressing part 12, the inner wall of the cover body 3 will abut against the pressing part 12, and because the pressing part 12 is provided with a deformation groove 14, the pressing part 12 will squeeze the deformation groove 14 to reduce the gap of the deformation groove 14, thereby deforming the pressing part 12 and producing a tightening effect in the direction of the seal 2, so as to finally achieve the pressing part 12 surrounding the seal 2 and pressing the seal 2 in the through hole 13. It is understandable that the pressing part 12 is made of an elastic material. In addition, the present application does not limit the shape of the deformation groove 14, and the deformation groove 14 only needs to have a deformation space.

[0036] Reference Figures 3 to 4 , and reference Figure 7 andFigure 8 As an embodiment, the pressing part 12 is provided with a convex ring 121 at the end away from the connecting part 11 and toward the through hole 13; the outer side of the sealing member 2 is provided with a notch 22 adapted to the convex ring 121. When the cover body 3 is connected to the connecting part 11, the convex ring 121 can be pressed against the notch 22, thereby increasing the contact area between the pressing part 12 and the sealing member 2, and further enhancing the pressing effect on the sealing member 2.

[0037] Reference Figure 4 and Figure 8 As an embodiment, the convex ring 121 includes a first pressing surface and a first contact surface, and the sealing member 2 is provided with a second pressing surface 221 and a second contact surface 222 corresponding to the notch 22. Figure 4 , the second pressing surface 221 can be perpendicular to the second contact surface 222. When the convex ring 121 is against the notch 22, the first pressing surface squeezes the second pressing surface 221, thereby achieving compression of the seal 2 on the circumferential side. At this time, the first contact surface can also be pressed against the second contact surface 222, and the first contact surface is facing the direction of the connecting portion 11, so as to limit the seal 2 and prevent the seal 2 from escaping from the through hole 13 and falling out of the installation box 1. It can be understood that when the cover body 3 is connected to the connecting portion 11, the pressing portion 12 is pressed against the circumferential side of the seal 2, firmly locking the seal 2 in the through hole 13, and also realizing the limiting function at the same time, and the cooperation between the first contact surface and the second contact surface 222 provides a double limiting guarantee.

[0038] Reference Figure 6 As an embodiment, the deformation groove 14 extends from the direction of the connecting portion 11 to the direction of the pressing portion 12, and the extension direction of the deformation groove 14 forms a preset angle with the first direction. It can be understood that in this embodiment, the deformation groove 14 is inclined, and in some examples, the angle between the extension direction of the deformation groove 14 and the first direction can be 15 degrees to 60 degrees.

[0039] Of course, according to the needs of the user, in some examples, the extension direction of the deformation groove 14 can also be set to be parallel to the first direction. For the convenience of description, the deformation groove 14 parallel to the first direction is defined as a straight groove, the deformation groove 14 set obliquely is defined as an oblique groove, and the part of the clamping part 12 located on both sides of the deformation groove 14 is defined as a tooth portion 122. Compared with the straight groove, the oblique groove can better form an overlapping effect between the teeth 122, thereby improving the sealing performance. In particular, when the cover body 3 is threadedly connected to the connecting portion 11, the inclination direction of the oblique groove converges to the direction of rotational connection of the cover body 3. At this time, multiple teeth 122 can also conform to the rotation of the cover body 3 to form an overlap.

[0040] As an embodiment, the seal 2 is elastic. Therefore, when the pressing portion 12 squeezes the seal 2, the seal 2 can be deformed, so that the seal 2 can be fully attached to the wire harness, improving the sealing effect, and constraining the wire harness to prevent the wire harness from being easily pulled out.

[0041] Reference Figure 3 and Figure 4 As an embodiment, the wire hole 21 of the seal 2 is through in the first direction; the seal 2 is provided with a cutout 23; along the radial direction of the through hole 13, the cutout 23 connects the external space of the seal 2 with the wire hole 21; along the axial direction of the through hole 13, the cutout 23 passes through the seal 2. Therefore, when the terminal of the wire harness to be passed through is relatively large and the terminal cannot pass through the wire hole 21, the user can insert the middle part of the wire harness into the wire hole 21 through the cutout 23, and the terminal does not need to pass through the wire hole 21. In this way, the work of passing the wire harness through the wire hole 21 can be completed. Due to the specific elasticity of the seal 2, the user can pry open the cutout 23 when inserting the wire harness through the cutout 23, and the seal 2 can return to its original state after the wire harness enters. On the other hand, the setting of the cutout 23 can also make the seal 2 further deform under the action of the pressing part 12, so that the inner wall of the wire hole 21 can fully fit the wiring harness, thereby further improving the sealing effect and constraining the wiring harness to prevent it from being easily pulled out.

[0042] In some examples, the seal 2 can be made of rubber material, so that the seal 2 can have good elasticity and resilience, can return to its original shape after being stressed, and maintain good sealing performance.

[0043] Reference Figure 4 As an embodiment, the cutout 23 is located at the position where the inner wall of the wire hole 21 is closest to the outer wall of the seal 2. Thus, the cutting area of ​​the cutout 23 is minimized, which can facilitate the processing and manufacturing of the seal 2. In addition, the cutout 23 is smaller, which can minimize the damage to the integrity of the seal 2, so that it can have a better sealing effect.

[0044] Reference Figure 3 In some examples, the number of the wire holes 21 can be set to 4. As required, the number of the wire holes 21 can also be set to 1, 2, 3, 5, etc. In addition, the size of the wire holes 21 can also be set according to the use requirements, and the wire holes 21 can be set to different diameter sizes.

[0045] Reference Figure 9As an embodiment, the cover body 3 includes a first covering portion 31 and a second covering portion 32 connected to each other, the first covering portion 31 is used for threaded connection with the connecting portion 11, and the inner wall of the second covering portion 32 is pressed against the pressing portion 12; the outer contour cross-section of the first covering portion 31 is a regular polygonal structure. Therefore, the outer contour of the first covering portion 31 can facilitate users to use external tools, such as wrenches, sockets and other tools, so that the first covering portion 31 can be tightly connected to the connecting portion 11. In some examples, the outer contour of the first covering portion 31 can be a regular hexagon. In addition, referring to Figure 7 The inner wall corresponding to the second covering portion 32 can be inclined so as to better squeeze the pressing portion 12 to tighten the sealing member 2 .

[0046] Specifically, the inner wall of the first covering portion 31 is provided with an internal thread, and the outer wall of the connecting portion 11 is provided with an external thread connected to the internal thread.

[0047] Reference Figure 9 As an embodiment, the outer wall of the first covering part 31 is provided with anti-slip grooves 33. The first covering part 31 with a regular polygonal outer contour has a plurality of screwing surfaces, which are used to contact with external tools. Thus, the anti-slip grooves can increase the friction between the first covering part 31 and the external tool to prevent the problem of slipping during the screwing process.

[0048] In some examples, the anti-skid pattern 33 may be provided in a partial area of ​​the screwing surface, but the anti-skid pattern 33 is located in the middle area of ​​the screwing surface. In other examples, the anti-skid pattern 33 may also be spread over the entire screwing surface.

[0049] Reference Figure 5 and Figure 7 As an embodiment, the connecting portion 11 includes a first connecting portion 111 and a second connecting portion 112, the first connecting portion 111 is connected to the pressing portion 12, and the first connecting portion 111 is detachably connected to the cover body 3; the second connecting portion 112 is connected to the side of the first connecting portion 111 away from the pressing portion 12, and the second connecting portion 112 is provided with a receiving cavity 1121 which is connected to the through hole 13, and the receiving cavity 1121 is used to receive the terminal for the external wiring harness. It can be understood that the terminals of some wiring harnesses are relatively large in size, and when the terminals are connected to the wiring board, the terminals will protrude from the wiring board. Therefore, the second receiving cavity 1121 can provide a space for receiving the wiring harness terminals.

[0050] Reference Figure 3 and Figure 5, as an embodiment, a connection hole 113 is provided on a side of the second connection portion 112 facing away from the first connection portion 111. The connection hole 113 is used to fix a screw to connect an external wiring board 100; the second connection portion 112 is provided with an avoidance groove 114, and the avoidance groove 114 is recessed from the radial direction of the connection hole 113 towards the accommodating cavity 1121. Thus, the provision of the avoidance groove 114 provides sufficient operating space when a utility tool tightens the screw, thereby improving the efficiency and accuracy of tightening the screw and also ensuring that the operation efficiency is not affected by the interference between the screw head and surrounding components during the assembly process.

[0051] In some examples, the connection hole 113 may be provided with 4 and evenly distributed on a side of the second connection portion 112 facing away from the first connection portion 111.

[0052] In some examples, a sealing gasket may also be provided on a side of the second connection portion 112 facing away from the first connection portion 111. Thus, when the second connection portion 112 is connected to the external wiring board 100, a good sealing effect can be formed in the second accommodating cavity 1121.

[0053] Referring to Figure 3 and Figure 5 , in some examples, the second connection portion 112 is further provided with a surrounding portion 115. In the radial direction of the connection hole 113, the surrounding portion 115 and the outer wall of the second connection portion 112 jointly enclose the connection hole 113. Thus, the provision of the surrounding portion 115 can enable the user to play a guiding and auxiliary positioning function when fixing the screw, and at the same time improve the structural strength of the second connection portion 112.

[0054] In some examples, both the installation box 1 and the cover body 3 can be made of plastic. Thus, plastic, as a light and easy-to-mold material, has obvious advantages in terms of cost, and its strength can meet the requirements for the wire passing box in related technologies.

[0055] The second aspect of the present application provides an energy storage container, which includes the above wire passing device.

[0056] In summary, the wire-passing device involved in the present application can remove the seal 2 from the through hole 13, so that by replacing the seals 2 with different numbers of wire-passing holes 21 or different sizes of wire-passing holes 21, it is widely applicable to a variety of electrical equipment, and different seals 2 can be flexibly replaced according to selection. When the seal 2 needs to be replaced, the cover body 3 and the installation box 1 are disassembled, and the new seal 2 is replaced, which is easy to operate. And the cost of replacing a single seal 2 is significantly lower than replacing the entire wire-passing device, which helps users reduce the cost of use. In addition, by connecting the cover body 3 with the connecting part 11, the pressing part 12 can press the seal 2, thereby constraining the seal 2, and the sealing effect is better. It can also prevent the seal 2 from being separated from the preset position, and avoid its rotation and the entanglement of multiple wire harnesses.
