[0027] Conductor 1 is fixedly positioned within the conductor 1 receiving cavity of the insulating shell. Its two ends form mutually perpendicular front contact piece 11 and rear contact piece 12, which extend to the mutually perpendicular side wall surfaces of the insulating shell. Rotating the front screw 4 and rear screw 5 causes the front screw 4 and rear screw 5 to move axially, thereby enabling the front screw 4 and rear screw 5 to engage with the front contact piece 11 and rear contact piece 12 respectively to clamp or release the wire. This allows the wire on one side to be connected to the front contact piece 11 and the wire on the other side to be connected to the rear contact piece 12. Through the special structure of conductor 1, this utility model enables the circuit inside the connector to form a 90-degree turn. When this connector is used in a controller panel, it can enable the circuit on the controller panel to be turned 90 degrees, thereby facilitating the connection of devices in different directions on site and providing convenience for wiring and connection in complex sites.

This structure is used for the connection of the three-phase lines between the controller and electrical equipment. This invention forms U-path, V-path, and W-path on the front side of the insulating housing, which are horizontal connections that can be connected to field equipment.

[0033] The conductor 1 has a flat plate structure, and the front contact piece 11 and the rear contact piece 12 are formed by bending along two mutually perpendicular sides of the conductor 1 in opposite directions. The conductor 1 and the front contact piece 11 and the rear contact piece 12 disposed on it are connected by sheet metal bending to form an integral conductor 1, which is convenient for processing and manufacturing and has low cost.

[0034] The conductor 1 has a square or L-shaped structure, and adjacent conductors 1 are nested together. The front contact piece 11 and the rear contact piece 12 are turned by the square or L-shaped conductor 1. Each conductor 1 is nested one by one by the L-shaped and square shapes, which occupies little space and is conducive to the miniaturization design of the connector.
