Patent ID: 7294022

Claim:
A vehicle power plug with a control switch, comprising: a hollow cylinder body having two mating semi-circular arc covers with one end sealed by an end cap and the other end socketedly connected to a seal cap, a snappingly engaged structure disposed therein, and a through line hole at an appropriate position running through its top and bottom; an electrode set disposed inside the body having a positive role and at least two negative poles which are axially and radially disposed, respectively, and protrude from a cover hole of the end cap and at least two opposite slots on the body, respectively, and two conductive blade clamps separately arranged on each of two sides of the snappingly engaged structure, one blade clamp being coupled with the positive pole and the other blade clamp and the negative poles being coupled with a power cord, respectively, and the power cord being extended out of the body through line holes; and a control switch having a press rod axially connected with a conductive blade, and the press rod connected with the snappingly engaged structure is machined to form a two-step locating structure with its one end of two opposite ends extending out of the body through a button hole; wherein the press rod extending out of the button hole of the body is applied with a force on the one end extending out of the body and the locating structure longitudinally displaces in the snappingly engaged structure of the body to be selectively located, so as to render the conductive blade contact with or separate from the two conductive blade clamps and thus to control the connection or disconnection with a power supply.
