Present invention relates to a roller construction with a sense of feel for a mobile navigation device; more particularly, relates to a construction for a mobile navigation device to produce a sense of feel when rolling the roller. Present invention comprises a conductive ring, a plurality of terminals and a support. The conductive ring is a hollow ring of conductive metal and the outer surface can be covered with insulating material. Each of the terminals comprises a contactor and the terminals are connected with the default circuit. Each of the contactor is plugged into the conductive ring to be electrically connected with it. The support comprises two braces, wherein each comprises a cantilever plugged in from each end of the conductive ring to support it. On rolling the conductive ring, regular interferences are made between the terminals and the conductive ring, or between the conductive ring and the cantilever, to produce a sense of feel.

Roller construction with a sense of feel for a mobile navigation device

The present invention is a roller construction with direction finding for a mobile navigation device. The present invention comprises a hollow conductive ring with several slots at an end, wherein a contacting area is set on the inner surface of the protruding part between each two neighboring slots; a support to plug the conductive ring; and a plurality of terminals plugged in from both two end surfaces of the conductive ring, wherein the terminals at one end surface are plugged in at the depth no deeper than the bottoms of the slots. By the simple structure of the present invention, the conductive ring interacts with the terminals, wherein the first rolling direction can be differed from the second rolling direction by signals sent with time differential.

Roller construction with direction finding for a mobile navigation device

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.

Mobile navigation device

An electronic card connector is described. The electronic card connector has a base and an upper lid. The base has a plurality of conductive terminals for transmitting/retrieving data signals for reading/retrieving data. The base has axles formed on distal ends of two sides thereof and protruded blocks on said two sides thereof. The upper lid has suspended arms positioned on the distal end of two sides of the upper lid and rotatably connects to the axles. The upper lid has buckling plates corresponding to the protruded blocks, and each of the suspended arms has a protrusion on a surface thereof. A track is formed on the axles of the base such that when the upper lid open or close, the axle of base allows the upper lid to rotate in an appropriate range to prevent damages to said electronic card connector.
