[0002] An automatic door refers to a control unit that can recognize the action of a person approaching the door (or a certain entry authorization) as an opening signal, open the door through a drive system, automatically close the door after the person leaves, and control the opening and closing processes. The DC power connection line of the automatic door is an important component for connecting the automatic door controller and the power supply.

[0003] The Chinese patent discloses a DC power connection line (authorization publication number CN 221328253 U). In this patented technology, a fixing sleeve limits the connection plug through a sleeve plate, and then an elastic band and an arc-shaped clamping plate fix the position of the connection plug through the sleeve plate, achieving the advantage of not being easily detached. The plug of the DC power connection line is not easily detached due to accidental touch, which is convenient for users. However, its fixing method realizes the fixing effect through the clamping and cooperation of the components on the plug and the mating parts on the plug-in device, and multiple mating parts need to be installed on the plug-in device, which is time-consuming and laborious. Therefore, those skilled in the art provide a DC power connection harness for an automatic door to solve the problems raised in the above background art. Content of the Utility Model
