Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a motor wiring device. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy. It uses a powered coil to generate a rotating magnetic field and acts on the rotor to form a magnetic-electromotive force to rotate the torque. Electric motors are divided into DC motors and AC motors according to the power supply used. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors. The motor is mainly composed of a stator and a rotor. The direction of the force on the current-carrying wire in the magnetic field is related to the direction of the current and the direction of the magnetic flux lines. The working principle of the motor is that the magnetic field acts on the force on the current, causing the motor to rotate.

[0003] Existing motor wiring generally uses a junction box as a wiring device. The junction box can protect the wires, but most of the junction boxes are not equipped with a fastening mechanism. After the bolts age, the internal wires may become loose, and the wires will fall off from the inside of the junction box, causing the motor to not operate normally. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a motor wiring device, which solves the problem that most junction boxes are not provided with a fastening mechanism, and the internal wires may become loose after the bolts age, so that the wires will fall off from the inside of the junction box, causing the motor to not operate normally.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a motor wiring device, including a base, a wiring connector is arranged on the top of the base, a fastening mechanism is arranged in front of the wiring connector, the fastening mechanism includes a fixed base, an n-shaped mounting frame, a sliding rod, a spring, an upper clamping plate and a pull rod, the n-shaped mounting frame is located above the fixed base, the sliding rod is located at both ends inside the n-shaped mounting frame, the upper clamping plate is located above the fixed base, the two ends of the fixed base are slidably connected to the sliding rod, the spring is located on the surface of the sliding rod, and the spring is located between the upper clamping plate and the n-shaped mounting frame.

[0006] Preferably, the lower end of the pull rod passes through the top of the N-shaped mounting frame and is fixedly connected to the upper clamping plate.

[0007] Preferably, wire grooves are provided on adjacent sides of the upper clamping plate and the fixed base.

[0008] Preferably, connecting plates are provided at both ends of the n-shaped mounting frame, and the connecting plates are fixedly connected to the top of the base by fixing bolts.

[0009] Preferably, a rotating shaft is installed at the rear end of the top of the base, and a box cover is connected to the surface of the rotating shaft.

[0010] Preferably, mounting plates are fixedly mounted on the front and rear ends of both sides of the base, and mounting holes are formed on the mounting plates.

[0011] The utility model provides a motor wiring device, which has the following beneficial effects:

[0012] The spring is between the upper clamping plate and the N-shaped mounting frame, thereby pressing the upper clamping plate downward to fix the wires between the upper clamping plate and the fixed base. The sliding rod prevents the upper clamping plate from shifting when moving and can press firmly on the surface of the wires, so that the wires will not fall off from the connector after the bolts age, thereby preventing sudden falling off and causing accidental damage to the motor.

The spring 34 is between the upper clamping plate 35 and the n-shaped mounting frame 32, thereby pressing the upper clamping plate 35 downward to fix the wires between the upper clamping plate 35 and the fixed base 31. The sliding rod 33 prevents the upper clamping plate 35 from shifting when moving and can firmly press on the surface of the wires, so that the wires will not fall off from the connector 2 after the bolts age, thereby preventing sudden falling off and causing accidental damage to the motor.

[0019] See also Figure 1-3 The lower end of the pull rod 36 penetrates the top of the n-shaped mounting frame 32 and is fixedly connected with the upper clamping plate 35. The upper clamping plate 35 is moved upward by pulling the pull rod 36, so that the wire is released, thereby facilitating the replacement of the wire.

[0020] See also Figure 1-3 , the upper clamping plate 35 and the adjacent side of the fixed base 31 are provided with a wire groove 4. Through the wire groove 4, the wires can be better limited and fixed between the upper clamping plate 35 and the fixed base 31.

[0021] See also Figure 1-3 , connecting plates 5 are provided at both ends of the n-shaped mounting frame 32, and the connecting plates 5 are fixedly connected to the top of the base 1 by fixing bolts. The connecting plates 5 are installed on the top of the base 1 by fixing bolts, which is convenient for disassembly and replacement when the fastening mechanism 3 is damaged.

[0022] See also Figure 1-3 A rotating shaft 6 is installed at the rear end of the top of the base 1, and a box cover 7 is connected to the surface of the rotating shaft 6. The box cover 7 prevents dust from entering the wiring device on the base 1.

[0023] See also Figure 1-3 The front and rear ends of the base 1 are fixedly mounted with mounting plates 8, and mounting holes 9 are provided on the mounting plates 8. The mounting plates 8 and mounting holes 9 are conveniently mounted on the motor and are convenient to disassemble when damaged.

[0024] During operation, the upper clamping plate 35 is pulled up from above the fixed base 31 by pulling up the pull rod 36, and the wires are passed through the wire groove 4 between the upper clamping plate 35 and the fixed base 31 to connect with the connector 2. When the wires are inserted into the connector 2, the pull rod 36 is released, and the spring 34 will bounce the upper clamping plate 35 back to the top of the fixed base 31, thereby fixing the wires in the wire groove 4 between the upper clamping plate 35 and the fixed base 31, so that the wires will not fall off from the connector 2 after the bolts are aged, thereby preventing sudden falling off and causing accidental damage to the motor.

[0025] The motor wiring device solves the problem that most junction boxes are not provided with a fastening mechanism, and the internal wires may become loose after the bolts age, so that the wires will fall off from the inside of the junction box, causing the motor to not operate normally.
