Detailed Embodiment

[0019] The following illustrates the embodiments of the utility model through specific specific examples. Those skilled in the art can easily understand other advantages and effects of the utility model from the content disclosed in this specification. The 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 utility model. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0020] It should be noted that the drawings provided in the following embodiments only illustrate the basic concept of the utility model in a schematic manner. Therefore, only the components related to the utility model 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 ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0021] All directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, horizontal, vertical...) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0022] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of the present invention may actually be an approximately parallel relationship, and the vertical relationship may actually be an approximately vertical relationship.

[0023] The utility model provides a switch cabinet special-shaped busbar clamp structure, which is used for installing and fixing the busbar in the switch cabinet, wherein the busbar 4 is used for installing and fixing the copper bar 5, and the special-shaped busbar clamp structure comprises a fixed clamp block 1, a movable clamp block 2, a bolt 31, and a combination nut.

[0024] Reference Figure 1 One side of the fixed clamp block 1 forms a first abutting surface, and the first abutting surface is recessed to form a first plug-in profile 11. One side of the movable clamp block 2 forms a second abutting surface, and the second abutting surface is recessed to form a second plug-in profile 12. The fixed clamp block 1 and the movable clamp block 2 are matched to form a whole, wherein the matching direction is set to make the first abutting surface opposite to the second abutting surface. After matching, the first plug-in profile 11 and the second plug-in profile 12 are combined to form a mounting groove 13 for accommodating the busbar 4. Preferably, the inner peripheral wall of the mounting groove 13 forms an interference fit with the outer peripheral wall of the busbar 4 to fix the busbar between the fixed clamp block 1 and the movable clamp block 2.

[0025] The fixed clamp block 1 is provided with a first circular hole, and the movable clamp block 2 is provided with a second circular hole. The inner diameter of the first circular hole is the same as the inner diameter of the second circular hole. When the fixed clamp block 1 and the movable clamp block 2 are matched, the first circular hole and the second circular hole are coaxial and connected to form a mounting hole 3 for passing the combination nut.

[0026] Reference Figure 2 The combination nut includes a hexagonal nut 32, which is inserted into the mounting hole 3 and located in the middle of the mounting hole 3. The bolts 31 include two, which enter the mounting hole 3 from the openings at both ends of the axial direction of the mounting hole 3, respectively. The two bolts 31 are connected to the two ends of the hexagonal nut 32, respectively. After tightening, the two bolts 31 form a mutually abutting force on the fixed clamp block 1 and the movable clamp block 2, thereby achieving the fixing effect of the fixed clamp block 1 and the movable clamp block 2.

[0027] At the same time, refer to Figure 4, when installing the fixed clamping block 1, first bring one end of the fixed clamping block 1 close to the positions with holes or slots on the bends, partitions 6, crossbeams, columns, etc. inside the switch cabinet. After passing the bolt 31 through the hole or slot, then pass it through the mounting hole 3, thereby fixing the fixed clamping block 1 inside the switch cabinet.

[0028] The fixed clamping block 1 and the movable clamping block 2 are made of insulating materials, including but not limited to ceramics, rubber, etc., and form an insulating relationship with the busbar 4; further, the hexagon nut 32 and the bolt 31 are usually made of metal materials. In the case of fixing the busbar through the fixed clamping block 1 and the movable clamping block 2, in order to ensure the creepage distance between the busbar and the hexagon nut 32, a sheath 33 is coaxially sleeved outside the hexagon nut 32. The sheath 33 is made of insulating materials, including but not limited to ceramics, rubber, etc., to increase the creepage distance between the busbar and the hexagon nut 32 and ensure safety.

[0029] Refer to Figure 3 , the busbar 4 has a straight bar-shaped structure and passes through the installation groove 13 along the straight line direction. It is clamped and fixed by the fixed clamping block 1 and the movable clamping block 2. The busbar 4 can be a C-shaped structure, so that a strip-shaped opening is formed on its side wall. The busbar 4 forms a fixed fit with the busbar clamp through the bottom end. The middle and top of the busbar 4 are used for fixedly connecting the copper bar 5. In order to prevent the busbar 4 from deforming due to excessive lateral external force when bearing at the top, protrusions are provided on the inner wall of the installation groove 13, which are used to extend into the strip-shaped opening and abut against the inner wall of the busbar 4 to form a support for the C-shaped structure.

[0030] Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
