摘要： A connector plug can be removably snap-fitted into the adapter which has a cavity into which the connector plug is inserted and a hole for locking the connector plug. The connector plug has: an optical fiber; a ferrule; housing; an elastic engagement piece with an projecting engagement portion and a projecting press portion, the engagement portion being adapted to snap into the hole of the adapter and become locked there when the connector plug is inserted into the adapter; and a stopper for locking the elastic engagement piece from being pressed. A height of the projecting press portion is set almost flush with a surface of the housing of the adapter, or is set almost equal to the height of the receptor portion of the adapter. Therefore, the connector plug can easily be connected to and disconnected from the adapter and its connection with the adapter is not easily broken.

摘要： In an optical connector structured having an optical connector ferrule accommodated in a housing urged towards the butt connection direction by an urging means, a technology is developed wherein the application of an external sideways force to the optical connector ferrule in a connected state is prevented, and the connected state is stably maintained. An optical connector 20 is provided wherein a positioning support part 24 which accommodates and supports a freely detachably a stop guard 26, which projects from the optical fiber ferrule 2, is provided in a housing 21; when this optical connector ferrule 2 is moved towards the butt connection direction, the stop guard is accommodated in the positioning support part 24 and positioned and supported; and when this stop guard 26 is released from the positioning support part 24, floating of the optical connector ferrule 2 in the housing 2 is permitted. Thereby, even if a sideways pressure is applied to the housing 21, a displacing force is not applied to the optical connector ferrule 2, and the butt connection state with the other optical connector ferrule is not affected.

摘要： An optical connector that provides a housing body 21 and a fixed part 22 that are installed so as to hold a backplane 3, and connects an optical connector plug 4b inserted into said housing body 21 via an installation hole in said backplane 3 and another optical connector plug 4a inserted into said housing body 21 from the direction opposite to that of said optical connector plug 4b, wherein flexible claws 25 projecting from both sides of said fixed part 22 engage said housing body 21 via said installation hole 30 in said backplane 3, and thereby said backplane 3 is held between said housing body 21 and said fixed part 22. Simply by adjusting the floating range (amount of floating) of the flexible claws 25 within said installation hole 30 the floating range (amount of floating) of the housing body 21 can be reliably set. Thereby, when the housing body 2 engages the printed board housing, the dimensional error is offset reliably by the floating of the housing body 21, and the engagement is carried out smoothly. A special order part for setting the floating range of the housing body 21 is not necessary, and thus a lower cost is possible and assembly can be carried out easily. In addition, a structure can also be used wherein the flexible claws projecting from the housing body side engage the backplane by passing through the installation hole, and the backplane is held between the bearing walls on the side of the housing body.
