[0034] Please refer to Figures 1-6 As shown in the drawings, the utility model provides a kind of power cabinet without cable technical scheme: a kind of power cabinet without cable, including cabinet 1 and hinged on cabinet 1 cabinet door 2, the lower end of cabinet door 2 is installed with mounting seat 3, and mounting hole on mounting seat 3 is installed with several wiring assemblies 4 for being connected with electrical element in cabinet 1.Junction. Wiring assembly 4 includes electrically conductive column 401, snap ring 405, inner wiring cable 407 and reset component 408. Electrically conductive column 401 is fixedly installed in the mounting hole in the end of mounting seat 3, and the upper side of the side end surface of electrically conductive column 401 is integrally formed with fixed electrically conductive sheet 402, and the lower side of the side end surface of electrically conductive column 401 is provided with several sliding grooves 403, and dynamic electrically conductive sheet 404 is slidably connected in sliding groove 403, and the end of dynamic electrically conductive sheet 404 is slidably connected with sliding groove 403 by being provided with sliding block and having electrically conductive capacity, wherein fixed electrically conductive sheet 402 plays a major role in electrically conductive, and dynamic electrically conductive sheet 404 plays a role in auxiliary electrically conductive. Snap ring 405 is sleeved on the outside of fixed electrically conductive sheet 402 and dynamic electrically conductive sheet 404, and the upper end of mounting seat 3 movably installs several adjusting parts 406, and adjusting part 406 is connected with snap ring 405 and is used to adjust the tightness of snap ring 405, wherein snap ring 405 can be a throat clamp, and adjusting part 406 is adjusting bolt on throat clamp, and the diameter of throat clamp is adjusted by rotating bolt to realize tightness adjustment. Inner wiring cable 407 is connected to one side of electrically conductive column 401 in cabinet door 2, and inner wiring cable 407 is used to connect the terminal of electrically conductive column 401 with electrical element inside cabinet 1. Reset component 408 is installed on the inside of fixed electrically conductive sheet 402 for assisting the reset of dynamic electrically conductive sheet 404.

[0035] When the external electrical equipment needs to be connected with the power cabinet, or the power cabinet needs to be expanded, the cable end of the electrical equipment or the expanded power cabinet is inserted between the inner arc of the fixed conductive sheet 402 and the movable conductive sheet 404, and then the engineer can rotate the adjusting part 406 by a tool to drive the clasp 405 to contract radially. As the clasp 405 contracts, the movable conductive sheet 404 moves along the sliding groove 403 towards the fixed conductive sheet 402, so that the cable end to be connected is compressed in the fixed conductive sheet 402 and the movable conductive sheet 404, achieving the effect of stable connection. When it is needed to disconnect the cable from the power cabinet, the adjusting part 406 is rotated in the opposite direction to loosen the clasp 405, and the cable end is loose after the movable conductive sheet 404 loses the compression of the clasp 405, and can be pulled out.

[0036] Through the wiring assembly 4, the effect of quickly connecting the cable of the external electrical equipment or the expanded cabinet with the power cabinet is achieved, and the end of the cable does not need to be pressed with copper wire nose to ensure good connection performance. The operation is simple, secondary rewinding is avoided, disassembly is convenient, the practicality and application flexibility of the power cabinet are improved, and it is more in line with the actual use demand of the current power cabinet.

[0037] The reset assembly 408 includes a limiting card 4081 and a reset spring 4082. The limiting card 4081 is fixed on the lower side of the inner wall of the fixed conductive sheet 402. The end of the reset spring 4082 is movably installed in the limiting card 4081, and the reset spring 4082 is limited in the fixed conductive sheet 402 in a compressed state, and the end thereof tends to be opened. Without external force, the reset spring 4082 maintains a downward tendency under the tension of the end thereof and pushes the movable conductive sheet 404 to the lowermost end.

[0038] When the cable end is inserted into the fixed conductive sheet 402 and the movable conductive sheet 404, the limiting card 4081 limits the depth of the cable end to avoid affecting the deformation of the reset spring 4082. When the clasp 405 compresses the movable conductive sheet 404, the movable conductive sheet 404 needs to overcome the inward contraction of the reset spring 4082. When the cable is removed, with the loosening of the clasp 405, the movable conductive sheet 404 moves to reset under the elastic action of the reset spring 4082, and enough space is reserved for the next time the cable end enters.

[0039] Through the reset assembly 408, the effect of quickly resetting the movable conductive sheet 404 after the cable is removed is achieved, the operation steps are simplified, the convenience of subsequent cable connection is ensured, and the reset spring 4082 always applies elastic force to the movable conductive sheet 404 to keep the connection of the adjusting part 406 and the clasp 405 tight, avoiding loosening in the later period.

[0040] The inner side of the cabinet door 2 is provided with an auxiliary frame 301 for improving the stability of the mounting seat 3. Since a large torque is required when the rotating adjusting part 406 is rotated, the auxiliary frame 301 can improve the mounting strength of the mounting seat 3.

[0041] The outer side of the conductive column 401, the fixed conductive sheet 402 and the movable conductive sheet 404 is provided with an insulating layer 5, which can avoid current guiding to the cabinet door 2 and the adjusting part 406, and ensure the safety of electricity use.

[0042] The conductive column 401, the fixed conductive sheet 402 and the movable conductive sheet 404 are all made of copper material, which has excellent conductivity and can bear certain deformation.

[0043] The fixed conductive sheet 402 and the movable conductive sheet 404 are both annular sheets with the same diameter of the inner arc.

[0044] The inner connecting cable 407 is a stretchable spiral cable, and the stretchability of the spiral cable ensures that the inner connecting cable 407 can be connected with any electrical element inside the cabinet body 1.

[0045] The working principle of the utility model is as follows:

[0046] When the power cabinet without wire is used, the inner connecting cable 407 is first connected with the specified electrical element inside the cabinet body 1. When the external electrical equipment needs to be connected with the power cabinet, or the power cabinet needs to be expanded, the cable end of the electrical equipment or the expanded power cabinet is inserted between the inner arc of the fixed conductive sheet 402 and the movable conductive sheet 404 until it is limited by the limiting clamp 4081. Then the engineer can rotate the adjusting part 406 by a tool to drive the clasp 405 to shrink radially, and with the shrinkage of the clasp 405, the movable conductive sheet 404 moves to the fixed conductive sheet 402 along the sliding groove 403 against the tension of the reset spring 4082, so that the cable end to be connected is pressed in the fixed conductive sheet 402 and the movable conductive sheet 404. When the cable needs to be removed from the power cabinet, the clasp 405 is loosened by reversing the adjusting part 406, and the cable end is loose after the movable conductive sheet 404 loses the pressing effect of the clasp 405, and can be pulled out. With the loosening of the clasp 405, the movable conductive sheet 404 is reset under the elastic action of the reset spring 4082.

[0047] The basic principle, main features and advantages of the utility model are shown and described above. It should be understood by those skilled in the art that the utility model is not limited by the above examples, and the above examples and descriptions in the specification are only preferred examples of the utility model, and are not used to limit the utility model, and various changes and improvements of the utility model can be made without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed. The protection scope of the utility model is defined by the appended claims and their equivalents.
