Estimating the term…
The identification terminals 16, 17 are entirely plated with solder, and additionally plated with gold near their extreme ends. This arrangement avoids increase of the contact resistance between the extreme end of the identification terminal 16 and the bulge of the identification terminal 17, keeping the contact resistance at 30 mΩ or below. The legs of the identification terminals 16, 17 are only plated with solder and not plated with gold. Hence, even if this shared electrical/optical transmission equipment 11 is left in the atmosphere, the solder-plated legs of the identification terminals 16, 17 do not deteriorate in solderability. Consequently, when the shared electrical/optical transmission equipment 11 is mounted on a substrate, the legs of the identification terminals 16, 17 can be soldered easily.
A shared electrical and optical transmission equipment of a plug-and-jack type, at least comprising a main body which contains an insertion port for selectively receiving either of a round optical plug or a single-prong electrical plug, an optical semiconductor chip which exchanges an optical signal with a round optical plug inserted in the insertion port of the main body, at least one terminal which makes electrical contact with a single-prong electrical plug inserted in the insertion port of the main body, a pair of identification terminals which make mutual contact when pushed by either of the round optical plug or the single-prong electrical plug inserted in the insertion port of the main body,
