Vehicle power plug with a control switch

Abstract

The present invention relates to a vehicle power plug with a control switch, comprising a body formed by two mating semi-circular arc covers; an electrode set having a positive pole and a negative pole; and a control switch having a press rod axially connected with an conductive blade, wherein a snappingly engaged structure is disposed in the body with two conductive blade clamps arranged on its two sides, respectively, one blade clamp being coupled with the positive pole, and the other blade clamp and the negative pole being coupled with a power cord, respectively, and then extending out of the body through line holes; consequently, the press rod extending out of a button hole of the body is applied with a force on its one end, 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 power supply.

Claims

1. 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 an 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 pole and at least two negative poles which are axially and radially disposed, respectively, and protrude from the cover hole of the end cap and at least two opposite slots 16 on the body, respectively, and two conductive blade clamps separately arranged on its two sides the snappingly engaged structure, one blade clamp being coupled with the positive pole and the other blade clamp and the negative pole being coupled with a power cord, respectively, and then extending out of the body through line holes;a control switch having a press rod axially connected with an 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 extending out of the body through a button hole;consequently, the press rod extending out of a button hole of the body is applied with a force on its one end 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 power supply.

2. The device according to claim 1, wherein a fuse is disposed between the positive pole and the positive lead, the positive lead is encompassingly connected within a spring and the rear side of the positive lead extends over a partition rib to couple with a conductive blade clamp.

3. The device according to claim 1, wherein the snappingly engaged structure comprises a pair of clamp tenon protrudingly disposed in the body and a pair of snapping rib protrudingly provided in the inner surface of the body corresponding to the clamp tenons, and the locating structure comprises two snapping slots longitudinally formed in the middle section of the press rod so as to render the two snapping ribs selectively snappingly engaged with the snapping slots by the longitudinally displacement of the press rod.

4. The device according to claim 1, wherein the positive pole and the negative pole are coupled with a display device to display the power status.

5. The device according to claim 1, wherein the display device is a LED light.

6. The device according to claim 1, wherein the press rod is machined to form a plate slot on the middle to socketingly connect with the conductive blade.

7. The device according to claim 1, wherein the end cap is a lens.

8. The device according to claim 1, wherein each arc cover is provided with an indented screw segment and two clamp edges on its respective end, such that the two covers may be screwed together by an end cap with an internal screw segment and socketingly connected with a seal cap whose circumference provided with a protruding ring.

9. The device according to claim 1, wherein the two conductive blade clamps are a shape of X with a gap between them.
