Description

Technical Field

[0001] This utility model relates to frequency converter technology, and in particular to a three-cabinet assembled frequency converter control device. Background Technology

[0002] A frequency converter (VFD) is a power control device that uses frequency conversion technology and microelectronics to control an AC motor by changing the frequency of its power supply. VFDs are widely used in production equipment across various manufacturing sectors, such as wire drawing machines, mixers, extruders, slitting machines, winding machinery, and centrifuges. VFDs require electrical connections to external devices via wires. Currently, VFDs use threaded connections for their electrical connectors. However, when the connector needs to be disassembled, the bolts can easily come loose from the threaded holes on the connector or the VFD. Reassembling the connector requires additional bolts, increasing maintenance costs. Therefore, a convenient and stable electrical connection structure is needed. Utility Model Content

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] like Figures 1 to 8 As shown, this utility model of a three-cabinet assembled frequency converter control device includes a cabinet 1 and an electrical connection component 2. The cabinet 1 is equipped with an electrical connector 3, which is used to connect external wires. The electrical connection component 2 enables rapid operation and achieves a stable connection.

[0024] Electrical connection assembly 2 is mounted on electrical connector 3. Electrical connection assembly 2 includes electrical connector base 4, rotating member 5, and electrical connector 6. Electrical connector base 4 is mounted on electrical connector 3, and a rotating hole 7 is formed in the center of electrical connector base 4. Rotating member 5 is disposed within rotating hole 7. Electrical connection hole 8 is formed in the center of electrical connector 6, and electrical connection hole 8 is fitted onto electrical connector base 4. An annular groove 9 is also provided in the center of electrical connector 6. A positioning member 10 is provided in the center of electrical connector base 4. After rotating member 5 rotates, it pushes positioning member 10 into annular groove 9.

[0025] The electrical connector 4 is provided with a mounting plate 11, and the mounting plate 11 can be fixed to the electrical connector 3 by bolts.

[0026] The electrical connector 4 has symmetrically arranged through holes 12, which communicate with the rotating hole 7. The diameter of the end of the through hole 12 facing the rotating hole 7 is larger than the diameter of the positioning member 10, and the diameter of the end of the through hole 12 away from the rotating hole 7 is smaller than the diameter of the positioning member 10. The positioning member 10 is a sphere, and the position of the positioning member 10 is restricted by the through holes 12, thereby ensuring that the positioning member 10 will not fall out from the end away from the rotating hole 7.

[0027] The rotating component 5 has symmetrically arranged arc-shaped grooves 13 and flat surfaces 14 in the middle. The arc-shaped grooves 13 and flat surfaces 14 are spaced apart. The distance between the lowest point of the arc-shaped groove 13 and the center line of the rotating component 5 is H1, and the distance between the flat surface 14 and the center line of the rotating component 5 is H2, where H1 < H2. When the positioning component 10 is in the arc-shaped groove 13, it can move within the through hole 12 and the arc-shaped groove 13, and it can also move within the annular groove 9. When the positioning component 10 is on the flat surface 14, it can only be kept within the through hole 12 and the annular groove 9 by the flat surface 14, so that the position of the positioning component 10 will not move. Through the cooperation between the positioning component 10 and the annular groove 9, the electrical connector 6 is restricted to the electrical connector 4.

[0028] A guide cone surface 16 is provided at the bottom of the electrical connection hole 8. The positioning member 10 can be pushed through the guide cone surface 16 to avoid affecting the installation of the electrical connector 6 because the positioning member 10 has not entered the arc groove 13.

[0029] The electrical connector 6 is provided with a conductor 17, and an insulating layer can be provided on the outside of the conductor 17 for easy handling. The electrical connector 6 is then fitted onto the electrical connector 4. Both the electrical connector 6 and the electrical connector 4 are made of conductive material.

[0030] A recessed groove 18 is provided within the rotating hole 7, and an annular protrusion 19 that mates with the recessed groove 18 is provided on the rotating component 5. The recessed groove 18 and the annular protrusion 19 can restrict the position of the rotating component 5, preventing it from easily moving out of the rotating hole 7. At the same time, the rotating component 5 is made of insulating material, which facilitates rotation. It can also be made of rubber material with a certain elastic deformation capability, which facilitates the installation of the annular protrusion 19 into the recessed groove 18 and allows the rotating component 5 to rotate, so that the positioning component 10 can move from the flat part 14 into the arc-shaped groove 13, and the positioning component 10 can also move from the arc-shaped groove 13 into the flat part 14.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
