Abstract
Description
Technical Field
[0001] This utility model belongs to the field of motor manufacturing technology, and specifically relates to a motor test terminal block. Background Technology
[0002] Before a motor leaves the factory, the motor manufacturer will test the motor to check its performance. A motor test terminal block is needed for this test, such as CN 210427641 U, entitled "A New Type of Terminal Block for AC Impedance Testing of Generator Rotors". This terminal block includes an upper epoxy plate (1) and a lower epoxy plate (2) of the same size. The upper epoxy plate (1) and the lower epoxy plate (2) are separated by a screw (3), which is connected to the upper epoxy plate (1) and the lower epoxy plate (2) by upper and lower fixing bolts respectively. The upper epoxy plate has multiple fixing holes for terminals (4). The terminals (4) are connected to external instruments by inserting test leads or by using inserts. The terminals (4) are fixedly connected to the upper epoxy plate (1) by bolts below the terminals (4). A connection line between the terminals (4) is provided in the middle of the upper epoxy plate (1), and the connection line between the terminals (4) is soldered. The connection between the terminals (4) is made of 6 square millimeters pure copper single-core hard wire. The upper epoxy board (1) is provided with two rows of terminal panels, the upper terminal panel is provided with input and output terminals, and the lower terminal panel is provided with voltmeter, ammeter and wattmeter terminals; the voltmeter, ammeter, wattmeter, input and output terminals are provided with corresponding voltmeter, ammeter, wattmeter, input and output markings, and the wattmeter terminal is marked with the same name of the voltage and current terminals. This new type of generator rotor AC impedance test terminal block requires OT terminals to function. Specifically, the ends of the six wires in the motor (two sets of three wires each) are each equipped with OT terminals. However, some customers require pin-type terminals for the six wires in their motors. This forces motor manufacturers to manufacture the six wires as OT terminals during production to meet testing requirements, only to re-cut the wires and replace them with pin-type terminals after the test is passed. This results in a waste of both wiring and labor time. To solve this problem, we have designed a motor test terminal block. Utility Model Content
