Description

Actuator with cable management frame

This creation relates to an actuator for lifting a door, window switch or equipment, and more particularly to an actuator with a cable management frame.

The actuator mainly uses the motor as the power, and then the screw end is used to make the load end move linearly, so that the linear actuator is widely used in life, such as lifting tables and chairs, etc. The height of the lifting table and chair can be adjusted at the load end to meet the needs of users.

Among them, a limit switch is installed inside the actuator, and the limit switch is used to detect the position of the load end, thereby calculating the number of times the load end passes through a certain point or controlling the load end to return at the limit position. However, when the wires (power lines, signal transmission lines, etc.) of the limit switch are not securely assembled, the wires are easily entangled in the screw, which will cause the wires to be short-circuited or damaged, and even the actuators will not work.

In view of this, the author has devoted himself to the above-mentioned existing technologies, researched intensively and cooperated with the application of theories to try his best to solve the above problems, which has become the goal of the creator's improvement.

This creation provides an actuator with a cable management frame. The cable management frame is installed inside the casing. The wires of the limit switch are wound and organized through the cable management frame to increase the assembly stability and safety of the actuator. .

Based on the above, the hollow outer tube is provided with a slot, and the limit switch and the cable management frame can be moved to the slot to facilitate the adjustment of the positions of the limit switch and the cable management frame, so that the wires are concentrated in the hollow tube. On the same side, the actuator has the advantage of convenient collection and collection of wires.

Based on the above, the housing further includes a top cover, the top cover covers the slot, and the cable management frame has a cable management arm sandwiched between the top cover and the hollow outer tube.
