Description

Technical Field

[0001] This application relates to the technical field of motor control devices, and specifically to a mounting and fixing device for a motor restart controller. Background Art

[0002] In factories and enterprises, when encountering dual-power switching or a power failure with a power outage time greater than 1 s, the release of the contactor will cause unplanned production downtime, resulting in economic losses and safety hazards; for this reason, some important motors need to be restarted after a short power recovery.

[0003] In the prior art, a motor restart controller has been used to ensure the safe restart of important motors, ensure production continuity, avoid impacting the power grid, and ensure power stability. For example, a patent for an anti-voltage-sag contactor anti-misoperation release device with the patent application number CN202022024617.0 uses a locking mechanism to realize the disassembly and assembly of the voltage disturbance restart mechanism and the mounting plate. The locking mechanism is actually a hook connection or disconnection between two sets of rotating frames and slots. It is necessary to press two sets of turning rods simultaneously to make the rotating frame rotate. This structure is inconvenient for users to operate with both hands simultaneously and is prone to breaking the rotating frame. Utility Model Content

[0020] Please refer to Figures 1-5, this embodiment provides a mounting and fixing device for a motor restart controller, including a motor restart controller body 1, a tightening member 2, and a power connection socket 3; one end face of the motor restart controller body 1 is provided with a plurality of terminal pins 110; the power connection socket 3 is installed on a carrier, which can be a frame or a mounting cabinet, and the two can be connected by screws. The power connection socket 3 is provided with through holes for the screws to pass through. And the power connection socket 3 is provided with connection holes 310 corresponding to the terminal pins 110 for insertion; both ends of the tightening member 2 are rotatably connected to the two side walls of the power connection socket 3; when the motor restart controller body 1 and the power connection socket 3 are connected through the terminal pins 110 and the connection holes 310, the tightening member 2 rotates and sleevs the outer wall of the motor restart controller body 1 to fasten the connection between the motor restart controller body 1 and the power connection socket 3.

[0021] Working principle: A plurality of terminal pins 110 of the motor restart controller body 1 are butted and inserted into a plurality of corresponding connection holes 310 of the power connection socket 3, and the two obtain a basic connection. On the one hand, it is the connection for electrical signal transmission, and on the other hand, it is a general connection for structural stability. At this time, the tightening member 2 automatically hangs down due to gravity and does not block the direct plugging and unplugging connection of the terminal pins 110 and the connection holes 310 of the motor restart controller body 1 and the power connection socket 3. The user can hold the motor restart controller body 1 with one hand and operate the tightening member 2 to rotate with the other hand, so that it sleevs the outer wall of the motor restart controller body 1 to fasten the connection between the motor restart controller body 1 and the power connection socket 3. Or the user can also operate the tightening member 2 to rotate and sleev the outer wall of the motor restart controller body 1 with one hand; in this way, under the action of the tightening member 2, the motor restart controller body 1 is restricted to prevent it from separating from the power connection socket 3, and the operation is convenient and fast without additional disassembly tools.

[0022] When it is necessary to disconnect the motor restart controller body 1 from the power connection socket 3, operate the tightening member 2 to cancel the sleeving of the motor restart controller body 1, and rotate it relative to the power connection socket 3 so that it automatically hangs down due to gravity and does not block the motor restart controller body 1, that is, the terminal pins 110 of the motor restart controller body 1 can be pulled out to disconnect the connection with the power connection socket 3 for replacement or debugging.

[0023] Preferably, the tightening member 2 is an elastic metal wire.

[0024] An elastic metal wire is selected as the tightening member 2, which has a simple structure, low cost, and is convenient for production, assembly and manufacturing. The tightening member 2 can be equal to or slightly smaller than the outer contour of the side of the motor restart controller body 1 in size, and is expanded and sleeved through its own elastic deformation. After the user cancels the pulling, it can be tightly fastened to the outer wall of the motor restart controller body 1 to enhance the connection strength.

[0025] Please refer to Figure 1 and Figure 5 Taking the center line 6 of the tightening member 2 as the boundary, the tightening member 2 includes two groups of symmetrically arranged hook segments 210, straight segments 220, and inner fold segments 230; one end of the hook segment 210 extends into the inner cavity of the power connection socket housing 3 and is rotatably connected to the power connection socket 3, and there is a first gap 4 between the outer hook segment 210 and the outer walls of the motor restart controller body 1 and the power connection socket 3; the straight segment 220 abuts against the outer wall of the motor restart controller body 1; the connection endpoints of the two inner fold segments 230 abut against the end face of the motor restart controller body 1; from the connection endpoints of the two inner fold segments 230 to the region where the inner fold segment 230 is connected to the straight segment 220, there is a second gap 5 between the inner fold segment 230 and the end face of the motor restart controller body Figure 5 .

[0026] Both the first gap 4 and the second gap 5 can provide space for the deformation of the tightening member 2 when it is pulled, which is convenient for the distance between the tightening member 2 and the outer wall of the motor restart controller body 1 to be enlarged, and for operating the tightening member 2 to sleeve or cancel the sleeve of the motor restart controller body 1. The second gap 5 is convenient for the user to operate and hold the tightening member 2 with fingers.

[0027] Preferably, the outer wall of the elastic metal wire is coated with an insulating layer.

[0028] Please refer to Figure 2 The upper and lower side walls of the power connection socket 3 are provided with wiring parts 320 corresponding to the connection holes 310.

[0029] The wiring part 320 is used to connect with the wire and cable. The wiring part 320 includes an inlet hole, a wiring terminal and a fastening screw.
