Description

Technical Field

[0001] The utility model relates to the technical field of electric actuators, in particular to an electric actuator housing which is convenient for wiring. Background Art

[0002] Electric actuators use electric motors as the driving source to convert electrical energy into mechanical energy to achieve motion control. Its main components include motors, reduction gearboxes, actuators, and controllers. Under the control of the controller, the output shaft of the motor is transmitted to the actuator through the reduction gearbox, thereby driving the movement of the actuator.

[0003] After searching, the patent document with publication number: CN213425216U discloses a wiring structure of an electric actuator; it sets a wiring assembly located in the slide slot, presses the protrusion, and the through hole on the limit block coincides with the central axis of the wiring slot. At this time, the wire is inserted into the inside of the through hole, and the protrusion is released. The limit block clamps the wire inside the wiring slot under the action of the spring, realizing the ability of the wiring assembly to quickly connect wires while preventing the battery cell from being damaged. By setting a clamping block located on the limit block, the clamping block and the slide slot are engaged, so that the limit block is restricted inside the slide slot, and the limit block is prevented from sliding out of the slide slot under the action of the spring. In actual use, after the wiring is connected, the above-mentioned wiring structure cannot be waterproofed at the wiring point and the inside of the wiring slot. When used outdoors later, rainwater can easily enter the wiring position along the gap of the wiring assembly, affecting its normal use. Utility Model Content
