Detailed Description

The present invention is described in detail with reference to the embodiments shown in the drawings, but it should be understood that these embodiments are not intended to limit the present invention, and those skilled in the art should understand that the functions, methods, or structural equivalents or substitutions made by these embodiments are within the scope of the present invention.

The utility model provides a discharge connector, it includes: female seat and with female seat matched with public end.

The technical solution of the discharge connector of the present invention is exemplified below with reference to an embodiment.

As shown in fig. 1 to 3, the discharge connector includes: female seat 1 and with female seat 1 matched with public end 2.

When charging, the female socket 1 is matched with the male end 2 in a plugging mode to receive charging current from the male end 2. The female block 1 includes: the portable electronic device comprises a base body 11, a plug-in end 12 arranged in the base body 11 and facing an opening end of the base body 11, a power supply hole 13 and a signal pin hole 14, wherein the power supply hole 13 and the signal pin hole 14 are arranged on the plug-in end 12.

The inserting end 12 is a cylinder, a fool-proof strip-shaped groove 15 is formed in the outer side wall of the inserting end, and the strip-shaped groove 15 extends along the opening direction of the opening end of the seat body 11.
