Detailed ways

Example 1

This embodiment provides a power connector for a Christmas tree, the structure of which is shown in Figures 1 to 8, including a male intubation 1 and a female intubation 6, and a male plug 2 and a female plug 5 that match each other. The front end of the shoulder 2-3 of the male plug 2 has an inner cavity with a positioning function, and an inner groove 2-4 is provided in the inner cavity with a positioning function, and a male plug terminal 3 is inserted into the inner cavity 2-4 with a positioning function. Inserting, the male plug 1 is socketed in the male cannula through the anti-movement structure; the female plug 5 has a cavity for receiving the male plug, and an inner boss 5-4 is arranged in the cavity. The size of the inner boss 5-4 matches the size of the inner cavity with positioning function of the male plug. The structure is socketed in the female cannula; the male plug terminal is two metal posts, and the female plug terminal is two hollow metal posts with open ends, through which the male plug terminal is inserted into the female plug terminal to contact and connect the power supply; the male cannula inserts the socketed male plug into the cavity of the female plug in the female cannula, and the outer diameter of the hollow tube of the male plug is smaller than the inner diameter of the cavity of the female plug.

The side wall of the inner cavity with positioning function and the outer side wall of the inner boss of the male plug in this embodiment are provided with a fool-proof limit structure, and the fool-proof limit structure is an outer convex platform arranged on the side wall of the inner cavity with a positioning function and an inset platform on the outer wall of the inner boss. The anti-tampering structure includes the male plug buckle 2-1 and the male plug limiting groove 2-2 on the outer wall of the male plug 2, and the female plug buckle 5-1 and the female plug limiting groove 5-2 on the outer wall of the female plug 5, the male cannula locking groove 1-1 arranged on the male cannula and the male cannula limiting boss 1-2 on the inner wall of the male cannula, the female cannula locking groove 6-1 set on the female cannula and the female cannula limiting boss 6-2 on the inner wall of the female cannula , The male/female plug cooperates with the limiting groove on the plug and the limiting boss on the cannula to prevent circumferential rotation, and prevents axial movement through the buckle of the male/female plug and the card slot provided on the male/female cannula and the shaft shoulder of the male/female plug; the buckle is an elastic sheet extending from the male/female plug, and there is a block on the elastic sheet that matches the size of the slot.
