[0002] An underground energy storage cabinet is a new type of energy storage device that buries the energy storage system underground. It is mainly used to solve the problems of space occupation, safety and heat dissipation that exist in traditional ground energy storage systems. The core of the underground energy storage cabinet is to integrate the battery module, battery management system, energy conversion system, thermal management system and related control and protection units into a sealed, pressure-bearing and corrosion-resistant cabinet, which is buried underground.

[0003] Junction boxes not only serve as electrical connection hubs for energy exchange between the battery packs inside the cabinet and external systems, but also provide protection for electrical wiring harnesses. However, existing junction boxes have complex internal structures, limited wiring space, and messy wiring harnesses, making fault diagnosis and maintenance extremely inconvenient. Therefore, this application proposes a new technical solution. Utility Model Content

[0004] To make the wiring harness inside the junction box more organized and facilitate fault diagnosis and maintenance, this application provides a wiring protection device.

[0005] This application provides a wiring protection device, which adopts the following technical solution:

[0006] A wiring protection device includes a housing, guide plates, a gathering plate, and a gathering component. The housing is hollow inside with an opening on its upper surface. A cover is rotatably connected to the opening side of the housing. Two guide plates are provided, located at opposite ends of the housing. Each guide plate includes a horizontal plate and a vertical plate fixed perpendicular to the horizontal plate. The horizontal plate is fixedly connected to the inner side wall of the housing, and the vertical plate is fixedly connected to the inner wall of the housing. Wiring holes for energy storage cabinet wiring harnesses to extend into the housing are respectively opened at both ends of the housing and on the bottom wall below the horizontal plate. Guide holes for wiring harnesses to pass through are opened on the vertical plate. The guide holes correspond to the wiring holes. The gathering plate is located inside the housing and its extension direction is along the opening direction of the guide holes. The gathering component is connected to the gathering plate and is used to gather and fix the wiring harnesses extending from the guide holes to the gathering plate.

[0007] Optionally, the gathering component includes cable ties, and the gathering plate has several equally spaced tying holes. The two ends of the cable tie are respectively inserted through two tying holes and wrapped around the wire harness before being tightened to gather and fix the wire harness to the side wall of the gathering plate.

[0008] Optionally, multiple guide holes and gathering plates are provided. The number of gathering plates is the same as the number of guide holes. The gathering plates are arranged and distributed inside the box, and the positions of the gathering plates correspond one-to-one with the positions of the guide holes.

[0009] Optionally, the gathering plate is detachably connected to the inner wall of the box, and a support frame is fixedly connected to the inner wall of the box. The support frame has a sliding groove for the side of the gathering plate to slide into, and the support frame is provided with a fixing component for fixing the gathering plate.

[0010] Optionally, the gathering plate has a slide rail along the longitudinal direction, and a limiting block is slidably connected in the slide rail. The lower surface of the limiting block is used to abut against the wiring harness. A spring is provided in the slide rail, with one end of the spring fixedly connected to the inner wall of the top of the slide rail and the other end fixedly connected to the end of the limiting block located in the slide rail.

[0011] Optionally, the lower surface of the limiting block is provided with an arc-shaped groove for contacting the wire harness.

[0012] Optionally, the fixing member includes an L-shaped fixing rod, one end of which is rotatably connected to the side wall of the support frame via a torsion spring, and the gathering plate has a slot for the other end of the fixing rod to be inserted.

[0013] Optionally, the lid is provided with a locking element for tightly closing the lid to the opening of the box body.

[0021] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0022] This application discloses a wiring protection device.

[0023] Reference Figure 1 and Figure 2 The wiring protection device includes a housing 1, a guide plate 2, a convergence plate 3, and a convergence component. The housing 1 is hollow inside and has an opening on its upper surface. A cover 4 for closing the opening is hinged to the side wall of the opening of the housing 1. There are two guide plates 2, which are respectively located at both ends inside the housing 1. The guide plate 2 includes a horizontal plate 21 and a vertical plate 22 fixed perpendicularly to the horizontal plate 21. One end of the horizontal plate 21 is fixed to the inner side wall of the housing 1 by bolts. The other end of the horizontal plate 21 is integrally formed with the upper end of the vertical plate 22. The lower end of the vertical plate 22 is fixed to the bottom wall of the housing 1 by bolts.

[0024] Reference Figure 2 and Figure 3 At the bottom of both ends of the box 1, below the horizontal plate 21, there are wiring holes 5 for the energy storage cabinet's wiring harness to extend into the interior of the box 1. The vertical plate 22 has guide holes 6 for the wiring harness to pass through. The guide holes 6 correspond to the wiring holes 5, so that the energy storage cabinet's wiring harness can extend into the interior of the box 1 from the wiring holes 5 at the bottom of the box 1.

[0025] In this embodiment, a terminal block with integrated terminals or an independent terminal block can be installed on the lower surface of the horizontal plate 21 of the guide plate 2. External cables can be inserted from the wiring hole 5 at the other end of the box 1, pass through the guide hole 6, and connect to the energy storage cabinet wiring harness. Thus, the gathering plate 3 is set on the inner wall of the box 1 and its extension direction is set along the opening direction of the guide hole 6, so that the length direction of the gathering plate 3 is consistent with the length direction of the wiring harness. The wiring harness is gathered and fixed on the gathering plate 3 by the gathering component.

[0026] To make it easier to distinguish and manage the wiring harnesses of the battery clusters in the energy storage cabinet, multiple guide holes 6 can be provided. In this embodiment, two guide holes 6 are provided side by side on the vertical plate 22, and the wiring harnesses of one battery cluster pass through one guide hole 6. Correspondingly, two gathering plates 3 are arranged in the box 1, so that the wiring harnesses of one battery cluster are fixedly gathered on one gathering plate 3, which facilitates later identification and maintenance.

[0027] With the above settings, the wire harness extends into the inner cavity of the box 1 through the wiring hole 5 and passes through the guide hole 6, so that the wire harness is neatly pressed against the gathering plate 3, and the gathering component fixes the wire harness on the gathering plate 3 to prevent the wire harness from being messy, making the wire harness inside the junction box more orderly, which is convenient for subsequent fault diagnosis and maintenance.

[0028] Reference Figure 2 The gathering component includes cable ties (not shown in the figure). The gathering plate 3 has several equally spaced tying holes 31 that run horizontally through it. By passing the two ends of the cable tie through the two tying holes 31 from the back side of the gathering plate 3 (the side facing away from the wire harness), and then wrapping the two ends that pass through the tying holes 31 around the back of the wire harness, the two ends of the cable tie are tightened. This fixes the wire harness to the gathering plate 3 by passing the cable tie through the tying holes 31, thus restricting the movement of the wire harness. The cable tie mentioned above is prior art and has a built-in structure that allows the two ends of the cable tie to be tightened together, so it will not be described in detail.

[0029] Reference Figure 4 To ensure that the lid 4 is tightly closed to the opening of the box body 1, the lid 4 is provided with a locking element 11. The locking element 11 includes a snap-fit ​​strip 111, an assembly block 112, and a locking rod 113. The assembly block 112 is cylindrical and fixedly inserted into the lid 4. The locking rod 113 is rotatably inserted into the assembly block 112 via a bearing. The upper end of the locking rod 113 has a locking groove for inserting a pre-matched key. The lower end of the locking rod 113 extends out of the lower end of the assembly block 112 and is fixed to the snap-fit ​​strip 111 by bolts. By rotating the locking rod 113, the locking rod 113 drives the snap-fit ​​strip 111 to rotate, thereby extending the side edge of the opening of the box body 1 inward, so that the end of the snap-fit ​​strip 111 can rotate to below the edge extending from the opening of the box body 1, so that the snap-fit ​​strip 111 abuts against the inside of the opening of the box body 1, and the lid 4 is tightly closed at the opening of the box body 1.

[0030] Based on the above, in addition to the wiring hole 5, the bottom of the box 1 can also have wiring holes to facilitate the routing of other communication cables as needed.

[0031] Reference Figure 5 In another embodiment of this application, considering that the cable ties need to pass through the tying holes 31 when bundling wire harnesses, in order to facilitate operation, the gathering plate 3 can be removed from the box 1, and the two ends of the cable ties can be passed through the tying holes 31 in advance, thus the following configuration is made:

[0032] The inner wall of the box 1 is fixedly connected with a vertical support frame 7 by bolts. The support frame 7 is a pair of strip structures. The gathering plate 3 is slidably inserted between the two strip structures. Specifically, the opposite side walls of the two support frames 7 are provided with longitudinal grooves. The two sides of the gathering plate 3 are slid into the grooves, so that the gathering plate 3 can be detachably connected. Therefore, the gathering plate 3 can be pulled out from the box 1 first, the cable tie can be passed through the cable hole 31, and then the gathering plate 3 can be inserted into the support frame 7. Then the cable tie can be wrapped around the wire harness to tie the wire harness tightly.

[0033] To prevent the gathering plate 3 from shifting off the support frame 7, the support frame 7 is equipped with a fixing component, which includes an L-shaped fixing rod 8. One end of the fixing rod 8 is hinged to the side wall of the support frame 7. The gathering plate 3 has a slot corresponding to the fixing rod 8 for the other end of the fixing rod 8 to be inserted. To ensure that the end of the fixing rod 8 can be smoothly inserted into the slot, the size of the slot is larger than the size of the end of the fixing rod 8. By installing a torsion spring at the hinge point between the fixing rod 8 and the support frame 7, the torsion spring applies a force to the fixing rod 8, causing it to always move towards the gathering plate 3, thus ensuring that the end of the fixing rod 8 can be stably inserted into the slot, thereby restricting the movement of the gathering plate 3.

[0034] Considering that during the process of bundling wire harnesses with cable ties, some wires in a bundle may stick out due to the presence of multiple wires, a mechanism is designed to hold the wire harness in place. Therefore:

[0035] Reference Figure 5 The gathering plate 3 has a longitudinally extending slide rail 9. A limiting block 91 is slidably connected within the slide rail 9, extending horizontally out of the slide rail 9 towards the wire harness. A spring 92 is installed within the slide rail 9. One end of the spring 92 is fixedly connected to the inner top wall of the slide rail 9, and the other end is fixed to the upper surface of the limiting block 91 located within the slide rail 9. The lower surface of the limiting block 91 has an arc-shaped groove 93 for contacting the wire harness. By using the spring 92, the arc-shaped groove 93 on the lower surface of the limiting block 91 can abut against the wire harness, applying pressure to prevent the wire harness from lifting and facilitating the operator to bundle the wire harness with cable ties. It should be noted that the selected spring force parameter of the spring 92 will not cause pressure damage to the surface of the wire harness.

[0036] 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.
