When the pressing part 3 is rotated counterclockwise by 167°, the elastic piece 10 is just in contact with the power cable 1, and a cutting edge of the elastic piece does not cut into the power cable, so that the elastic piece 10 can tightly press the power cable smoothly.
In this way, the connection of the power cable 1 can be realized, and the present invention is more convenient to use.
The disconnection method, i.e., the removal method, is further elaborated below. The power cable disconnection method includes the following steps.
S401: The release button 39 is pushed upward. After the release button 39 moves upward, the first chamfers 44 enter into contact with the second chamfers 45 respectively arranged on the first leg 17 and the second leg 18, and the first leg 17 and the second leg 18 are slightly opened outward, so that the knife switch boss 37 is disengaged from the release button accommodating groove 36.
S402: The pressing part 3 is rotated clockwise.
S403: The power cable 1 is taken out.
In this way, in a practical removal process, the power cable can be removed without using any other removal tool. In addition, no parts are damaged during the removal process, thereby achieving the purpose of reusing the power cable connector and saving resources.
