[0023] In the existing technology, the traditional method for manufacturing such insulating boxes or insulating covers in the industry is injection molding. However, due to the characteristics of insulating boxes, such as deep cavities or thin walls, their mold design is complex, the mold opening cost is high, and structural modifications to the product become extremely difficult and costly.

[0024] This utility model proposes an insulating box.

[0025] Please see Figures 1 to 3 In one embodiment of this utility model, the insulating box includes: a main board 100, a side plate 200, a first end plate assembly 300, and a second end plate assembly 400; wherein, the main board 100 is connected to both sides of the side plate 200, and a first fold line 110 is provided between the main board 100 and the side plate 200, and the side plate 200 and the main board 100 are folded along the first fold line 110 to form a first accommodating space; the first end plate assembly 300 is connected to one end of the main board 100, and the first end plate assembly 300 is provided with a second fold line 310, and the first end plate assembly 300 is folded along the second fold line 310 to define a second accommodating space; the second end plate assembly 400 is connected to the end of the main board 100 away from the first end plate assembly 300, and the second end plate assembly 400 is provided with a third fold line 410, and the second end plate assembly 400 is folded along the third fold line 410 to define a third accommodating space, and the first accommodating space, the second accommodating space, and the third accommodating space are interconnected and are respectively used to accommodate electrical components.

[0026] It should be noted that the insulating box proposed in this utility model contains and covers electrical components, such as circuit board assemblies or electrical appliances, and plays an insulating and shielding role. It also has a certain degree of foldability. Therefore, it can be understood that the insulating box is made of insulating material, such as PC or PP.

[0027] In this embodiment, the main board 100, side plate 200, first end plate assembly 300 and second end plate assembly 400 have a certain strength. In order to facilitate folding, several through holes are opened at intervals along the folding line during the specific implementation process, but this does not affect the overall strength.

[0028] In this embodiment, a first fold line 110 is provided between the motherboard 100 and the side panel 200. Side panels 200 are provided on both sides of the motherboard 100. The side panels 200 are folded at a certain angle relative to the motherboard 100 along the first fold line 110, so that the side panels 200 and the motherboard 100 form a first accommodating space. The first end plate assembly 300 and the second end plate assembly 400 are respectively connected to opposite ends of the motherboard 100. Depending on actual needs, the first end plate assembly 300 and the motherboard 100, as well as the second end plate assembly 400 and the motherboard 100, can be folded or not, and this is not limited here. The first end plate assembly 300 is provided with at least two second fold lines 310, so that the first end plate assembly 300 is folded to form a second accommodating space.

After folding, the first accommodating space, the second accommodating space and the third accommodating space are connected and adapted to the distribution of electrical components that need to be covered and accommodated, so as to ensure the shielding and insulation effect.

[0029] This utility model's technical solution employs a first folding line 110 between the main board 100 and the two side plates 200, allowing the two side plates 200 to fold relative to the main board 100, thereby forming a first accommodating space. A first end plate assembly 300 is connected to one end of the main board 100, and a second end plate assembly 400 is connected to the other end. The first end plate assembly 300 is provided with the first folding line 110 and folds to define a second accommodating space. The second end plate assembly 400 is provided with a second fold and folds to define a third accommodating space. The first, second, and third accommodating spaces are interconnected and each accommodates electrical components, thereby achieving shielding and insulation. Compared to the prior art of forming an insulating box through injection molding, this utility model's technical solution, by defining the insulating box for accommodating electrical components through mutual folding, eliminates the need for injection molding, significantly reducing mold costs and facilitating the structural design of the insulating box, thus lowering overall production costs.

[0030] In one embodiment, the first end plate assembly 300 includes a first main end plate 320 and a first side end plate 330. The first main end plate 320 is connected to the main board 100. A first cutting seam 210 is provided between the first side end plate 330 and the side plate 200. The first side end plate 330 is provided on both sides of the first main end plate 320. A second folding line 310 is provided between the first main end plate 320 and the first side end plate 330. After folding, the first side end plate 330 is connected to the side plate 200.

[0031] Specifically, first side end plates 330 are connected to both sides of the first main end plate 320. The first side end plates 330 are folded relative to the first main end plate 320 via a second fold line 310, thereby defining a second accommodating space. Furthermore, a first cutting seam 210 is provided between the first side end plate 330 and the side plate 200, thereby improving the folding flexibility of the first side end plate 330 and forming second accommodating spaces of different shapes. This also facilitates designing the connection position between the first side end plate 330 and the side plate 200 according to requirements, achieving different effects.

[0032] Furthermore, the first side end plate 330 and the side plate 200 are each provided with a first connecting hole 220. The first connecting hole 220 is also connected to a first connecting member, which is used to fix the first side end plate 330 and the side plate 200. In specific implementation, the first side end plate 330 and the side plate 200 have the first connecting holes 220. After the entire insulating box is folded, the first connecting member, such as an insulating rivet, passes through the two first connecting holes 220 and locks in place, thereby achieving the connection and fixation of the first side end plate 330 and the side plate 200. Further still, the first side end plate 330 is provided with a connecting portion that extends and overlaps with the side plate 200, further improving the convenience and stability of the connection between the first side end plate 330 and the side plate 200.

[0033] In one embodiment, the first main end plate 320 includes a first connecting portion 321 and a second connecting portion 322, with a fourth fold line 323 between them. The second connecting portion 322 is connected to the main board 100, and a fifth fold line 324 is provided between the second connecting portion 322 and the main board 100.

[0034] Specifically, the first connecting part 321 and the second connecting part 322 are folded at a certain angle by a fourth fold line 323. After folding, the second connecting part 322 is tilted, thus forming a transition structure between the main board 100 and the first connecting part 321. This allows for a smooth transition between the two spaces with different internal cavity sizes, namely the first accommodating space and the second accommodating space. Furthermore, the second connecting part 322 is also folded at a certain angle relative to the main board 100 by a fifth fold line 324, so that the second end assembly can be folded to form the second accommodating space. The first connecting flange 340 of the first side end plate 330 has a second cutting gap 325 between it and the second connecting part 322. After folding, the first connecting flange 340 fits against the second connecting part 322 and is fixedly connected to it, such as by adhesive or by a locking member.

[0035] Furthermore, the first connecting flange 340 and the second connecting portion 322 are each provided with a second connecting hole 341. A second connecting member is connected to each second connecting hole 341, and the second connecting member is used to fix the first connecting flange 340 and the second connecting portion 322. Specifically, the second connecting member, such as an insulating rivet or pin, passes through the two second connecting holes 341 to fix the first connecting flange 340 to the second connecting portion 322. This improves the connection strength and stability between the first side end plate 330 and the first main end plate 320.

[0036] In one embodiment, the insulating box further includes a flap assembly 500, which includes a main flap 510 and a side flap 520. The main flap 510 is connected to the side of the first main end plate 320 opposite to the main board 100, and the side flap 520 is connected to the side of the first side end plate 330 opposite to the side plate 200. Both the main flap 510 and the side flap 520 are provided with an adhesive layer 530. When the insulating box is used to cover and shield electrical components, it needs to be fixed at the covering position or fixed to the electrical components. In this embodiment, both the main flap 510 and the side flap 520 are provided with an adhesive layer 530 to facilitate the fixing of the insulating box. In another embodiment, the main board 100 and / or the second end plate assembly 400 are provided with mounting holes 600. The mounting holes 600 are used to connect mounting fasteners, such as screws, which are fixed in their respective positions through the mounting holes 600. Furthermore, an opening is provided in the main flap 510 to facilitate the connection of connectors to the insulating box. A connecting plate is also connected between the main flip plate 510 and the first end main board 100 to improve the flexibility of flipping and attaching the main flip plate 510.

[0037] In one embodiment, the second end plate assembly 400 includes a second main end plate 420 and a second side end plate 430. The second main end plate 420 is connected to the main board 100.

A third fold line 410 is provided between the second main end plate 420 and the second side end plate 430. After folding, the second side end plate 430 is connected to the side plate 200.

[0038] Specifically, second side end plates 430 are connected to both sides of the second main end plate 420. The second side end plates 430 are folded relative to the second main end plate 420 via a third fold line 410, thereby defining a third accommodating space. Furthermore, a third cutting gap 230 is provided between the second side end plate 430 and the side plate 200, thereby improving the folding flexibility of the second side end plate 430 and forming third accommodating spaces of different shapes. This also facilitates designing the connection position between the second side end plate 430 and the side plate 200 according to requirements, achieving different effects.

[0039] In one embodiment, the second side end plate 430 and the side plate 200 are respectively provided with a third connecting hole 240. The third connecting hole 240 is also connected to a third connecting member, which is used to fix the second side end plate 430 and the side plate 200. In specific implementation, the second side end plate 430 and the side plate 200 have the third connecting holes 240. After the entire insulating box is folded, the third connecting member, such as an insulating rivet, passes through two of the third connecting holes 240 and locks in place, thereby achieving the connection and fixation of the second side end plate 430 and the side plate 200. Further, the second side end plate 430 is provided with a connecting portion, which is folded and extended, overlapping with the side plate 200, further improving the convenience and stability of the connection between the second side end plate 430 and the side plate 200.

[0040] Furthermore, the second main end plate 420 includes a third connecting part 421 and a fourth connecting part 422, and a sixth folding line 423 is provided between the two.

A fourth cutting gap 425 is provided between the second connecting flange 440 and the third connecting part 421. After folding, the second connecting flange 440 and the third connecting part 421 are fixedly connected.

[0041] Specifically, the third connecting part 421 and the fourth connecting part 422 are folded at a certain angle by the sixth fold line 423. After folding, the third connecting part 421 is tilted, thus forming a transition structure between the main board 100 and the third connecting part 421, allowing for a smooth transition between the two in the case of the first and third accommodating spaces with different internal cavity sizes. Furthermore, the fourth connecting part is also folded at a certain angle relative to the main board 100 by the seventh fold line 424 to facilitate the folding of the second end assembly to form the third accommodating space. The second connecting flange 440 of the second side end plate 430 has a fourth cutting gap 425 between it and the third connecting part 421. After folding, the second connecting flange 440 fits against the third connecting part 421 and is fixedly connected to it, such as by adhesive or by a locking member.

This improves the connection strength and stability between the second side end plate 430 and the second main end plate 420. Additionally, notches are provided in the first side end plate 330 and the second side end plate 430 to avoid obstructing components in fixed positions.
