Abstract

A mobile navigation device including a roller, a support, a plurality of terminals, and a body. The roller including an insulated bushing and a conductive ring. By matching the plurality of protrusions on an inner end surface of the insulated bushing with a plurality of slots on one end of the conductive ring, the conductive ring is plugged inside of the insulated bushing. The support including two braces, wherein each of the braces has a cantilever that is plugged into the conductive ring to sustain the conductive ring and the insulated bushing. The plurality of terminals are plugged into the conductive ring by prestress on the inner surface of the conductive ring, and each terminal extends out of the conductive ring to connect with a default circuit contact. The body includes a plurality of fixture parts and a plurality of raised spots. The whole structure is movable forward, backward, rightward, leftward, and downward.

Claims

1. A mobile navigation device comprising:

(1) a roller comprising an insulated bushing and a conductive ring, wherein said insulated bushing and said conductive ring are in a shape of hollow ring, and one side of an inner surface of said insulated bushing comprises a plurality of protrusions and said conductive ring comprises a plurality of slots, and said plurality of slots on said conductive ring is corresponding to said plurality of protrusions on one side of inner surface of said insulated bushing to plug said conductive ring into said insulating bushing;

(2) a support comprising two braces, wherein said braces comprise a corresponding cantilever for each, and said cantilevers are plugged into said conductive ring to sustain said conductive ring and said insulated bushing;

(3) a plurality of terminals, wherein said plurality of terminals are plugged into said conductive ring producing prestress on the inner surface and at least a pair of said terminals are plugged into said conductive ring at a depth no deeper than a bottom of said slot, and said plurality of terminals is extended out of said conductive ring to connect with default circuit contact; and

(4) a body comprising a plurality of fixture parts on one end surface of said body to fix said support, and a plurality of raised spots on two opposite sides of the other end surface of said body.

2. The mobile navigation device according to claim 1, wherein the inner surface of said insulated bushing is provided with blocks to block said conductive ring.

3. The mobile navigation device according to claim 1, wherein said insulated bushing is provided with said plurality of protrusions to wedge said plurality of slots to fix said conductive ring.

4. The mobile navigation device according to claim 1, wherein tips of said cantilevers connect with each other by prestress means.

5. The mobile navigation device according to claim 4, wherein the tips of said cantilevers connect with each other by means of matching concaves with convexes.

6. The mobile navigation device according to claim 1, wherein said plurality of terminals connect with electric board by contacting means.

7. The mobile navigation device according to claim 1, wherein said plurality of terminals connect with electric board by welding means.

8. The mobile navigation device according to claim 1, wherein a plurality of posts is on the middle of the opposite sides of end surface of said body.
