Patent ID: 8360659

Claim:
An optical plug connector ( 110 , 110 ′) for detachable connection of a plurality of optical cores ( 115 ) comprising: an insert ( 112 , 112 ′; 132 , 138 , 138 ′, 142 ) into which the optical strands ( 115 ) are inserted on a first side, in which the optical strands ( 115 ) end with their optical fibers ( 119 , 120 ), and which has a widening apparatus ( 114 , 125 , 131 , 139 , 139 ′) on a second side, on which the beams emerge widened from the fibers ( 119 , 120 ), the insert ( 112 , 112 ′; 132 , 138 , 138 ′, 142 ) including two separate partial elements ( 113 ; 114 , 125 , 131 , 139 , 139 ′) which can be joined together, one of the two separate partial elements in the form of a widening apparatus ( 114 , 125 , 131 , 139 , 139 ′) and the other of the two separate partial elements in the form of a holding block ( 113 ) for holding the ends of the optical strands ( 115 ), wherein the holding block ( 113 ) includes a strand hole ( 121 ) of a first diameter for each of the ends of the optical strands ( 115 ), which strand hole ( 121 ) extends into the holding block ( 113 ) on the first side and merges via an adjacent insertion cone ( 122 ) into a fiber hole ( 123 ) of a second diameter being substantially smaller than the first diameter, which ends on the opposite side of the holding block ( 113 ).
