Description

Technical Field

[0001] This utility model relates to the field of motor wiring technology, and in particular to a motor wiring device. Background Technology

[0002] A motor junction box is a protective device for electrical products and power supply connections. Its main function is to protect the motor body and provide convenience and safety for connection. The basic requirements for junction boxes include electrical clearance, creepage distance, protection level, installation and protection requirements, etc., to ensure that the motor can operate safely and stably.

[0003] The lead terminals of the dry ammonium blower motor and induced draft fan motor are buried inside the coil. When wiring, the condition of the terminals cannot be directly seen, and faults in the lead terminals cannot be directly detected, leading to motor failure. In addition, the cable diameter is large, while the junction box hole diameter is small. When the motor fails, it takes a long time to disconnect the wires and pull out the cable, requiring a long downtime, which is time-consuming and laborious, thus affecting the normal operation of production.

[0004] Therefore, this utility model provides a motor wiring device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to propose a motor wiring device that solves the problems of existing motor junction boxes, which make it impossible to visually observe lead wire faults when they occur. Furthermore, disconnecting the wiring and pulling out the cable takes a long time, is laborious, and affects normal production. This invention enables immediate detection of lead wire faults when a motor junction box malfunctions, and allows for quick cable removal, saving maintenance time and improving production efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a motor wiring device, comprising:

[0011] A connector is attached to the end of each terminal block away from the base, and the connector is detachably mounted to the base and is positioned opposite each other on the base; a connecting piece is connected between the connectors at the ends of the two terminals.

[0012] A side plate is slidably disposed on one side of the junction box. The side plate is used to slide out and quickly pull out the motor wiring cable together.

[0013] Preferably, the junction box has a mounting hole at the bottom for mounting a base; and rectangular grooves are provided on both vertical sides of one side of the junction box.

[0014] Preferably, the side plate has a circular hole for inserting an external cable, and the two sides of the side plate are respectively slidably engaged with the rectangular groove.

[0015] Preferably, the junction box is provided with a top cover.

[0016] Preferably, the terminal block has a bent structure.

[0017] Preferably, the connecting element is a bolt.

[0018] The beneficial effects of this utility model are:

[0019] 1. This utility model, by providing bent terminals inside the junction box, allows for quick observation and repair when a fault occurs in the motor lead wire, preventing greater safety hazards caused by lead wire faults and greatly improving the safety performance of motor operation.

[0020] 2. This utility model has a side plate on the junction box. By sliding the movable side plate, the cable can be quickly pulled out, saving maintenance time and improving production efficiency. Attached Figure Description

[0030] Also includes:

[0031] Multiple terminals 3 are evenly divided into two groups, and the two groups of terminals 3 are symmetrically distributed on both sides of the top of the base 2. The lead wires and terminals 3 are moved into the junction box 1 to facilitate timely detection of lead wire faults. This is to prevent greater safety hazards caused by lead wire faults in the motor and plays an important role in the safe operation of the motor.
