[0002] Currently, a terminal block for a motor includes a terminal block body, terminal posts, and lead holes. The terminal post body is generally circular, and the terminal posts are evenly distributed inside the terminal post body, while the lead holes are generally above the terminal posts, so that the leads installed on the terminal posts are led out from the lead holes and connected to other components. However, since the leads are led out from the top, if there are many leads, the leads will be complicated and the operation will be troublesome. The leads need to be installed on the terminal posts first and then led out from the lead holes. Since the lead holes need to be set up, it is also a waste of materials.
