Lens surrounded by magnet
A coupling system includes a first connecting unit and a second connecting unit adapted to be connected to each other. Each of the first connecting unit and a second connecting unit includes an enclosure with a substantial even mating surface and a pair of lens module. Each lens module includes a lens enclosed within a magnet, and the magnets of the coupled lens modules have opposite magnet poles around the corresponding mating surfaces. The pair of lens modules are further equipped with a transmitting chip and a receiving chip in aligned with the corresponding lens, respectively.
1. A coupling system comprising:
a first connecting unit similar to and coupled with a second connecting unit,
each of the first connecting unit and the second connecting unit including:
an enclosure enclosing both a printed circuit board and a pair of lens modules, the enclosure providing an even mating surface, each of the lens modules including a magnet enclosing a lens; wherein
at least the magnet of the lens module is exposed upon and flush with a mating surface; wherein
each of the first connecting unit and the second connecting unit further includes a single electrical connector mounted upon the printed circuit board between the pair of lens module and exposed upon the mating surface; wherein
said single electrical connector in the enclosure of the first connecting unit is of a pogo pin type slightly projecting out of the mating surface, while the electrical connector in the enclosure of the second connecting unit is of a pad type for complementarily complying with the pogo pin type; wherein each of the first connecting unit and the second connecting unit further includes an absorption device located beside the electrical connector and between the pair of lens modules to filter noise derived from a chip of each of the lens modules.
2. The coupling system as claimed in claim 1 , wherein the absorption device is exposed upon and essentially flush with the mating surface.
3. A connecting unit for use in a coupling system, comprising:
an enclosure enclosing both a printed circuit board and a pair of lens modules, the enclosure providing an even mating surface, each of the lens modules including a magnet enclosing a lens; wherein
at least the magnet of the lens module is exposed upon and flush with a mating surface;
further including a single electrical connector mounted upon the printed circuit board and exposed upon the mating surface; wherein
said single electrical connector is located between the pair of lens module; further including an absorption device located beside the electrical connector and between the pair of lens modules to filter noise derived from a chip of each of the lens modules.
4. The connecting unit for use in the coupling system as claimed in claim 3 , wherein the absorption device is exposed upon and essentially flush with the mating surface.
