<p>PROBLEM TO BE SOLVED: To provide a plug structure for insertion type optical rack/plug connection part. SOLUTION: An insertion type rack/plug connection part can be formed between at least one sleeve part 2 provided on a relatively fixed mother board 3 and a relatively mobile daughter board 5. The plug structure is provided with a plug housing 5 which is provided so as to be moved in the axial direction on the daughter board and a plug mouth piece 7 provided so as to receive a preliminarily loaded spring tension in the axial direction. The plug housing is provided with an engaging means 8 which engages the plug housing with an engagement position in the sleeve part. The plug housing 6 is supported directly or indirectly on a thrust element 9 having a spring action in the insertion direction of an arrow (x), and the spring force of the thrust element maintains this support up to the engagement position, and thereafter, it automatically releases the support when thrust motion is continued.</p> |
