hole that penetrates this optical connector adaptor are butted together and connected in the connector housing hole on a connection optical axis that is parallel with the center axis of the connector housing hole. In an optical connector receptacle, the optical connector (ferrule) that is incorporated within this optical connector receptacle and the optical connector (optical connector plug) that is inserted into the connector housing hole are butted together and connected on a connection optical axis that is parallel with the center axis of the connector housing hole.
When the plug compatible insertion portion has been inserted into the positioning housing, then in a state in which a central portion of the tape pressing surface of the head portion of the tape pressing head has been positioned above thecenter axis (i.e., an axis that passes through the center of the joining end surface and is parallel with the center axis of the connector housing hole of the positioning housing) of the optical connector within the positioning housing by the inner surface of the connector housing hole, the head portion presses the cleaning tape against the joining end surface of the optical connector within the positioning housing.
It should be noted that positioning housings such as optical connector adaptors and optical connectors are currently produced by a number of makers, however, there is a lack of uniformity in the accuracy of the positioning of the optical connector within the connector housing hole that is a result of the accuracy with which the positioning housing and optical connector are
