DETAILED DESCRIPTION

[0022] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0023] The term "multiple" as used herein refers to two or more than two. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0024] Figure 1 is a schematic structural diagram of a plug-and-play insulating isolation box provided in an embodiment of the present application, Figure 2 It is a bottom schematic diagram of a plug-and-play insulating isolation box. The junction box body 1 of the plug-and-play insulating isolation box is an integrated cast aluminum structure with a high bearing pressure. A wiring area is provided at the bottom of the junction box body 1. The present application has an insulating layer 2 attached to the front and back of the wiring area. The insulating layer 2 can be a coating layer or insulating sticker with low-voltage or high-voltage insulation to form an insulating isolation area. The box body of the insulating isolation area is an L-shaped insulating isolation board 3. Three conductive copper column threading holes 31 are provided on the insulating isolation board 3. The conductive copper columns of the three-phase electricity are passed through the conductive copper column threading holes 31 to the interior of the junction box body 1.

[0025] Figure 3 This is the internal structure diagram of the plug-and-play insulation isolation box. Figure 4 1 is a side view of a plug-and-play insulating isolation box. In some embodiments, the two sides of the insulating isolation plate 3 are respectively connected to the bottom surface of the junction box body 1. The length of the insulating isolation plate 3 is consistent with the length of the junction box body 1, and the bottom of the junction box body 1 is divided into two unequal heights of the first bottom surface 11 and the second bottom surface 12. Figure 1 The middle box body has the same overall height, but has two box bottom machine structures with different heights.

[0026] Figure 5 It is a schematic diagram of the bottom structure of the plug-and-play insulation isolation box. Based on the L-shaped plate structure, the insulation isolation plate 3 is divided into a horizontal plate 32 and a vertical plate 33. The horizontal plate 32 is connected to the first bottom surface 11, and the vertical plate 33 is connected to the second bottom surface 12. The conductive copper column threading holes 31 are designed to be circular and evenly distributed on the horizontal plate 31 of the insulation isolation plate 3. The conductive copper columns pass through the conductive copper column threading holes 31.

[0027] In order to further improve the stability of the insulating area, a sinking groove 34 is die-cast between adjacent conductive copper column threading holes 31 inside the box body, and a lower protrusion 35 is generated at the bottom of the horizontal plate 32. The two sides of the sinking groove 34 and the lower protrusion 35 are set to be arc-shaped, and the curvature matches the curvature of the conductive copper column threading hole 31. This structure prevents the column from shaking and tilting based on the enclosure of the lower protrusion 35 after the conductive copper column is inserted. In particular, the sinking groove 34 formed on the top surface of the horizontal plate 32 can be used as a buckle groove of the upper cover. For example, a convex structure is provided on the upper cover and inserted into the sinking groove 34 to achieve a tight installation, and the bearing capacity of the box body can also be further improved.

[0028] In some embodiments, positive and negative conductive holes 36 are symmetrically opened at both ends of the insulating isolation plate 3. Three conductive copper column threading holes 31 are inside. A spacer block 37 is arranged at the bottom area of ​​the horizontal plate 32 and between the positive and negative conductive holes 36 and the conductive copper column threading holes 31. The two sides of the spacer block 37 are arranged in an arc shape, and the arc matches the arc shape of the positive and negative conductive holes 36. The spacer block 37 has a similar function to the lower protrusion 35, both of which are to improve stability.

[0029] Figure 6 yes Figure 1 In the enlarged view of point A in the middle, a row of tooth-shaped through holes 38 are provided at the connection between the horizontal plate 32 and the first bottom surface 11. Correspondingly, a heat sink 111 matching the through hole 38 is provided on the first bottom surface 11. The heat sink 111 structure matches the shape of the tooth-shaped through hole 38. The heat sink 111 structure is inserted into the tooth-shaped through hole 38 and is staggered with the through hole 38. The heat sink is arranged at a position close to the conductive copper column in order to further improve the heat dissipation. The bumps, sink grooves and sink hole structures designed above are all covered with an insulating layer to ensure that the metal box structure does not leak out and achieve a stable insulation effect.

[0030] To summarize, the structure uses a junction box body with a cast filter structure to improve the overall pressure-bearing capacity and heat dissipation effect. An insulating layer is affixed to the isolation plate position of the wiring area on the box body. The insulating layer covers the conductive copper column threading holes, and spacer blocks and protrusions matching the arc shape of the conductive copper column threading holes are arranged at the bottom. The conductive copper column spacer blocks and protrusions are transmitted into the interior of the box body to improve stability.
