[0022] The following specific examples illustrate the embodiments of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0023] It should be noted that the illustrations provided in the following embodiments only schematically illustrate the basic concept of the present invention. Therefore, only the components related to the present invention are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and proportion of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0024] In the embodiments of the present invention, all directional indications (such as up, down, left, right, front, back, horizontal, vertical...) are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0025] Due to reasons such as installation errors, the parallel relationship referred to in the embodiments of the present invention may actually be an approximate parallel relationship, and the vertical relationship may actually be an approximate vertical relationship.

[0026] The present invention provides a miniaturized drawer structure for a switch cabinet. The drawer is arranged in the switch cabinet in a pull-out and movable manner. One end of the drawer located in the switch cabinet is provided with a primary connector 31. A busbar 5 is arranged in the switch cabinet. During the pulling process of the drawer, the connection / disconnection between the primary connector 31 and the busbar 5 is realized.

[0027] Specifically, referring to Figure 1 and Figure 2 , the drawer is of a square structure and includes a door panel 1, side plates 2, a bottom plate 4, a rear plate 3, and support beams. The upper part of the drawer is open. A partition is arranged in the switch cabinet. An active slide rail mechanism is arranged between the bottom plate 4 of the drawer and the partition to realize the pulling work of the drawer in the switch cabinet.

[0028] Referring to Figure 3 and Figure 4 , a plurality of busbars 5 are arranged in the switch cabinet. The busbars 5 are of a straight bar structure. Plug-in parts 51 are arranged on the busbars 5 along the straight line direction. The projection of the plug-in parts 51 in the straight line direction is in a linear structure, so that the plug-in parts 51 can be cooperatively connected with the sockets of the primary connectors 31. And due to the strip structure of the busbars 5, the primary connectors 31 can be connected with the plug-in parts 51 at any position in the straight line direction of the busbars 5.

[0029] Furthermore, multiple said busbars 5 can be arranged in a mutually parallel manner. Different primary connectors 31 installed on different busbars 5 can be distributed at different positions in the linear direction, forming a staggered arrangement of multiple primary connectors 31. Specifically, for example, when the busbars 5 are arranged vertically, multiple primary connectors 31 installed on different busbars 5 are distributed at different height positions, forming a stagger. Further, the distance between the arranged busbars 5 can be further reduced, enabling a more compact arrangement and distribution of multiple primary connectors 31, while also not interfering with each other. The installation area occupied by multiple primary connectors 31 in this setting is further reduced. Furthermore, the size of the rear panel 3 of the drawer used to install the above-mentioned primary connectors 31 can also be further reduced, thereby achieving the effect of miniaturizing the volume of the drawer.

[0030] Referring to Figure 5 , at any two right-angled sides of the side panel 2 of the drawer, a double-edge pressing structure formed by bending is adopted to strengthen the strength of the side panel 2, and further strengthen the structural strength of the drawer. Further, a handle hole 21 is opened on the side panel 2, which is used to provide a hand-held part for the user when the drawer is pulled out from the switchgear cabinet, so as to stably carry the drawer. Referring to Figure 6 , a sheath 22 is arranged on the circumference of the handle hole 21 to cover the sharp edge of the handle hole 21 and provide protection. The sheath 22 is made of rubber material. A round hole is opened on the side panel 2, and columnar bumps 221 are arranged on the sheath 22 for inserting into the round hole to realize the fixed installation of the sheath 22 on the side panel 2.

[0031] It further includes an anti-fall block 23. Referring to Figure 7 and Figure 8 , the anti-fall block 23 is fixedly installed on the side panel 2. The anti-fall block 23 is arranged at the top of the side panel 2. A guiding surface 231 in the form of a plane is formed on the top of the anti-fall block 23. The guiding surface 231 is flush with the top surface of the side panel 2 or slightly higher than the top surface of the side panel 2. A bump stop 232 protrudes upward on the guiding surface 231. During the process of pulling the drawer out of the switchgear cabinet, when most of the drawer is pulled out, due to the center of gravity being outside, the drawer is likely to slip. In this embodiment, there is a bend at the opening of the drawer of the switchgear cabinet. When the drawer is pulled out horizontally, there is still a height gap between the bump stop 232 and the bend, enabling the drawer to be smoothly pulled out. When the drawer is about to slip and causes the drawer to tilt, with the front end of the drawer tilting downward and the rear end tilting upward, the bump stop 232 can collide with the bend and be blocked by the bend at the opening of the drawer, preventing the drawer from further slipping.

[0032] A surrounding sealant is provided inside the door panel 1 of the drawer in the form of dot glue to ensure the protection level of the fitting surface between the door panel 1 and other profiles.

[0033] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.
