Abstract:
A connection-pin inserting-and-extracting apparatus including a connection-pin holding device which holds a connection pin for an inserting-and-extracting process and into-and-from a matrix switch board and has a holding mechanism holding said connection pin, a driving mechanism driving the holding mechanism, and a frame having mounted thereon the holding mechanism and the driving mechanism, wherein:said holding mechanism comprises:a sleeve having a first end part in which slits and nail parts are formed, and a second, opposite end part in which is formed a fixing parts mounted to said frame,a pair of swinging members facing each other, each including a hook and a lever, a middle part of each thereof being rotatably mounted to said frame, andthe swinging members being normally rotated so as to open said hooks;said driving mechanism comprises:a push rod supported by said frame and said sleeve in a slidable manner,an armature, of a magnetic substance, mounted to one end part of said push rod in a swinging manner,an electromagnet fixed to the frame so that a magnetic pole of the electromagnet faces said armature, andsaid push rod being resiliently urged so as to separate said armature from said electromagnet; andwhen a portion of said connection pin is inserted into a gap between said nail parts of the sleeve, said push rod moves relatively to the sleeve, the swinging members and the electromagnet, causing said armature to contact said electromagnet and causing projections, formed on the push rod, to push respective said levers of the swinging members thereby to close said hooks.
