Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some embodiments, not all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Examples

As shown in fig. 1 to 4, the present invention provides a power supply connector, which comprises: the plug comprises a socket 1, an outer toothed ring 2, a plug 3 and a fixed sleeve 4, wherein a plurality of guide posts on the socket 1 are matched with jacks on the plug 3, the outer ring of the outer toothed ring 2 is in a zigzag shape and is fixed below the socket 1, the fixed sleeve 4 is movably clamped on the plug 3, the fixed sleeve mainly comprises a movable ring A, a threaded ring B, a rubber ring C, an inner toothed ring D and a movable groove E, the movable groove E is arranged in the middle of the plug 3, the movable ring A is clamped on the movable groove E, the inner wall of the cylindrical inner hole of the threaded ring B is provided with threads and is fixed on the movable ring A, the rubber ring C is arranged on the movable ring A in a cylindrical hollow shape, the inner toothed ring D is fixed on the rubber ring C, the plug 3 and the socket 1 are respectively connected with circuits with different two ends and are connected with circuits at two ends when the socket 1 is in insertion matching with the plug 3, the outer ring of the socket 1 is provided with threads and is meshed with, the length of the threaded ring B is slightly greater than that of the socket 1, the length of the rubber ring C is slightly greater than that of the threaded ring B, and the inner gear ring D and the outer gear ring 2 are mutually clamped when the fixed sleeve 4 works.

The working principle of the present invention is explained as follows:

the plug 3 is correspondingly inserted into the socket 1, so that circuit interconnection at two ends is formed into a passage, the fixing sleeve 4 is moved to the upper part of the socket 1 by hands, the thread ring B is aligned to the peripheral thread of the socket 1, the fixing sleeve 4 is rotated to clamp the thread so as to tightly clamp the plug 3 on the socket 1, when the fixing sleeve 4 is rotated, the inner gear ring D is matched and clamped with the outer gear ring 2, the thread ring B is prevented from being loosened by rotating backwards, when the thread ring B needs to be unscrewed to release connection and fixation, the inner gear ring D is pressed downwards, the inner gear ring D is moved to be separated from the clamping with the outer gear ring 2 by contraction of the rubber ring C, and the thread ring B can rotate backwards to be in contact connection and fixed.
