Joint base

Abstract

The invention relates to the field of power tools, in particular to a joint base comprising a male plug and a female plug, wherein the male plug comprises a plug cylinder provided with a first connecting structure at the rear, and the inner side wall of the plug cylinder is provided with a conductive cylinder; the female plug comprises an insulation sleeve, a conductive insert and a lock cylinder;the conductive insert is arranged in the insulation sleeve, the lock cylinder is moveably sleeved outside the insulation sleeve, a second connecting structure is arranged at the front of the lock cylinder, and the lock cylinder and the insulation sleeve are respectively provided with a first limit structure and the second limit structure so as to limit the axial forward sliding of the locking cylinder; when the plug cylinder and the insulation sleeve are inserted, the conductive insert is inserted into and electrically connected to the conductive cylinder, and the movable locking cylinder canmake the second connecting structure and the first connecting structure cooperatively connect, so that the insulation sleeve and the plug cylinder cannot be disengaged from each other but can rotaterelative to each other. The joint base provided by the invention can realize quick connection of the male plug and the female plug with convenient operation, and the male plug and the female plug canbe freely rotated in the connected state to obtain flexible use.

Description

technical field [0001] The invention relates to the field of electric tools, in particular to a joint seat. Background technique [0002] The connector seat is generally used to fix and conduct conductive connection between the cable conductor and the electrical wiring part that needs to be wired (such as the terminal block in the distribution box). In the existing connector seat, the male plug and the female plug are generally connected by means of hooks. , the specific use needs to adjust the angle of the male plug and the female plug first so that the hanging pin and the hanging slot are opposite, then insert the male plug into the female plug and rotate a certain angle, so that the hanging pin is embedded in the hanging slot, so as to realize the male plug Connect with the buckle of the female plug. This connection method has the following problems: it is inconvenient to operate, and the angle between the male plug and the female plug needs to be adjusted before the mal...

AI Technical Summary

Problems solved by technology

This connection method has the following problems: it is inconvenient to operate, and the angle between the male plug and the female plug needs to be adjusted before the male plug can be inserted into the female plug; after the male plug and the female plug are connected, the male plug and the female plug cannot be rotated relative to each other , which will bring a lot of inconvenience in actual use, because the male plug and / or female plug are generally connected to the cable. Knotting or even damaging the cable will also bring inconvenience to the operation and construction. In addition, for cables with a thicker diameter, a relatively large recovery torque will be generated when the cable is twisted. Accidental disengagement of plug and female plug
