Abstract

The invention is a magnetic clip cord for a tattoo machine that comprises a pair of magnet bars, in which one magnet bar is mounted to an electrical cord and the other magnet bar is mounted on the frame of a tattoo machine. The invention consists of an electrical cord, a spring, a set screw, two steel bars, two brass connectors, two non-conductive collars, two magnet bars, and a tattoo machine. The invention is used by aligning the two magnets bar, and allowing the magnetic force to connect the two pieces, upon which a positive current will pass along to a tattoo machine when in use. The steel bars carry the negative current and shall connect upon alignment of the magnet bars. The primary feature of the present invention is to prevent tattoo artisan errors attributed to outside forces acting on the power cord that attaches to the tattoo machine being used, by providing a magnetic clip cord design.

Claims

1. An improved magnetic clip cord for a tattoo machine comprising:

(a) a magnet bar;

(b) a metal bar;

wherein along a top surface of the metal bar, at predetermined locations are big hole and a small hole;

wherein the metal bar has a shape that is slightly larger than a cross-section of the magnet, and is U-shaped, so that when placed over the magnet bar, the metal bar does not touch any surface of the magnet bar;

(c) a power cord consisting of a coaxially insulated positive wire and a coaxially insulated negative wire run throughout the power cord;

(d) a spring;

wherein the spring provides positive upward direction for a bottom of the power cord;

(e) a brass connector;

wherein a end of the positive wire protrudes from the bottom of the power cord and is permanently affixed to the brass connector;

(f) a screw;

wherein the end of the negative wire protrudes from the bottom of the power cord, through an opening in the spring, and is permanently affixed to the top surface of the metal bar by the screw at the predetermined location where the small hole exists; and

(g) a non-conducting collar;

wherein the non-conducting collar is fitted between the bottom surface of the big hole of the metal bar and the brass connector; and

wherein attached to a tattoo machine is a second metal bar and a second magnet bar with a second nonconducting collar and second brass connector;

wherein a power cord of the tattoo machine consists of a positive wire and a negative wire;

wherein the positive wire is attached to the second brass connector;

wherein the negative wire is attached to the second metal bar;

wherein the two magnet bars will attract each other via the magnetic force which will in turn cause both brass connectors to touch, and simultaneously cause both metal bars to touch, thereby enabling electrical current to pass to the tattoo machine; and

wherein the flow of electrical current to the tattoo machine is stopped by the separation of the two magnet bars.

2. The non-conducting collar as described in claim 1 wherein the non-conducting collar is made from a plastic.
