Description

Motor Connector Kit

The new model relates to a transmission line, in particular to a motor connector set used in electric bicycles or electric scooters.

Electric bicycles, electric scooters and electric vehicles are the same as today's Clean Technology Products. Among them, electric bicycles and electric scooters are important action vehicles for urban short-distance transportation. Among them, electric bicycles and electric scooters need to transmit signals through specific transmission lines in the transmission of signals and power. Since electric bicycles and electric scooters require a large amount of current in the process of starting, accelerating, etc., the current transmission line itself needs to be a transmission line (thicker) that can tolerate a large amount of current.

Please refer to FIG. 1A and FIG. 1B, which are the perspective view and the front view of the male end transmission line of the conventional electric bicycle and the motor connector for the electric scooter. The power connection is arranged on the top surface of the base body 10 of the male end transmission line. A male terminal 21-1, a power connection male terminal 21-2, and a power connection male terminal 21-3 are three power terminals in total; and a signal connection male terminal 22-1, a signal connection male terminal 22-2, and a signal connection male terminal are arranged. There are six signal terminals including a terminal 22-3, a signal connection male terminal 22-4, a signal connection male terminal 22-5, and a signal connection male terminal 22-6. The example in Figure 1A and Figure 1B is a 3+6 (3 power terminals, 6 signal terminals, including Hall signal lines) design, which is wire-to-wire and air-connected to the female transmission line (not shown). The female end transmission line has a protective cover ring, which can form protection after the nine male terminals of the male end transmission line are inserted into the female end transmission line. Generally speaking, the male transmission line is usually used for the motor, and the female transmission line is usually connected to the controller.
