## Abstract

Upon completion of the manufacturing of constituent elements of the charging coupler, waterproof members each with a predetermined shape and width are integrally formed, made from an appropriate material, and disposed at a predetermined portion and/or segment of the constituent elements. In consequence, a hermetic seal is effectuated between each of the constituent elements of the waterproof members and a corresponding one of adjacent related elements of the charging coupler to therefore prevent any gap from forming in the charging coupler after long use, thereby preventing intrusion of ambient moisture.

## Claims

### Claim 1

A waterproof mechanism of a charging coupler, with the charging coupler adapted to charge vehicles, comprising constituent elements comprising a charging coupler body, a charging coupler control unit disposed on an upper side of the charging coupler body, a press element pivotally connected to the charging coupler body, and a top end concealment element engaged with an upper end portion of the charging coupler body, wherein a lining element and a charging coupler connection unit are inserted sequentially into a terminal end of the charging coupler body, wherein a charging end unit is inserted into a front end of the charging coupler body, wherein waterproof members with a required shape and width are integrally formed at a predetermined portion or segment of the charging end unit and the charging coupler control unit and are made from an appropriate material; and wherein the constituent elements of the charging coupler, which require ambient moisture intrusion prevention, are in tight contact with adjacent constituent elements.

### Claim 2 (depends on 1)

The waterproof mechanism of a charging coupler according to claim 1, wherein one of the waterproof members coupled to the charging end unit is disposed in front of an engagement segment to effectuate an enhanced hermetic seal as soon as the charging coupler body is rotated and thus fastened in place.

### Claim 3 (depends on 1)

The waterproof mechanism of a charging coupler according to claim 1, wherein another one of the waterproof members of the charging coupler control unit is disposed at a waist segment centrally located to effectuate a hermetic seal as soon as the charging coupler body gets positional engagement within a predetermined receiving space.
