the wiring board mounting groove (2) is used for arranging a wiring board (4); the wiring board (4) is provided with a stud (5) and a screw hole;

the center of the shielded wire wiring boss (3) is provided with an internal thread hole (6) for being matched and connected with a bolt; the shielding wire of the power cable is arranged on the bolt of the shielding wire wiring boss (3), and is fastened by an elastic pad, a flat pad and a nut;

the structure also comprises a connecting sheet (15) which is sleeved on the stud (5); the stud (5) is also sleeved with a terminal (8), and the terminal (8) is positioned above the connecting sheet (15); one end of the wiring terminal (8) is provided with a round through hole (9); the other end of the first terminal is provided with a lug terminal (10); the round through hole (9) of the wiring terminal (8) is sleeved on the stud (5) of the wiring board (4) and is fastened by an elastic pad, a flat pad and a nut, and a lug terminal (10) of the wiring terminal is connected with a power line of the power cable.

The relevant content in the above technical solution is explained as follows:

in the above solution, the six-core power cable is provided with a shielding cable, and the connection manner of the cable between the motor and the controller belongs to a conventional electrical connection manner, which is known to those skilled in the art.

The utility model discloses theory of operation and advantage as follows: the utility model discloses take two six-core power cables, its inside shielding cable from taking, the connected mode that double-screw bolt and nut combined has been changed by the screw with the installation of current power line in addition, the use of deuterogamy bullet pad and flat pad, the firm connection fastening degree between the part under dynamic environment that can be fine to because the shielding cable sets up in the inside of cable, can not lead to the shielding to break down because of the vibration, the wiring structure of a whole set of motor makes the device operation more stable.
