Abstract:
1. An electrical/photoelectric conversion dual connector comprising: a first unit serving as an electrical connector element having an insertion hole in a body into which a contact is incorporated, a pin type optical plug and a pin-type electrical plug being selectively insertable into and extractable from said insertion hole, said pin type optical plug holding an end portion of an optical fiber, said pin-type electrical plug having a terminal that is to be connected to said contact; and a second unit serving as a photoelectric conversion connector element comprising a holder which is attachable to and detachable from a rear end portion of said body of said first unit, and which holds a photoelectric conversion device that, in an attached state, is placed coaxially with an optical axis of said optical fiber held by said pin type optical plug inserted into said insertion hole, wherein both said first and second units are formed as surface mounting type units, a first soldering terminal of a surface mount type disposed on said first unit is placed on a side portion of said body, and a second soldering terminal of the surface mount type disposed on said second unit is placed on a rear portion of said holder; and said holder comprises a pair of right and left arms which forward protrude to be longitudinally fittable into and extractable from said rear end portion of said body, and which, in a fitted state, overlap with right and left outer side faces of said rear end portion of said body, respectively, front end portions of said arms respectively comprise engaging claws which are to be engaged with engagement steps formed on right and left outer side faces of said body, to cooperate with a front end face of said holder to clampingly hold said rear end portion of said body, and a positioning protrusion is disposed integrally on said holder, said positioning protrusion being to be inserted into a recess formed in said rear end portion of said body to overlap with upper and lower wall faces of said recess, thereby restricting a level position of said second unit with respect to said first unit to make a level of a lower face of said second soldering terminal coincident with a level of a lower face of said soldering terminal.
