An inter-lens adjusting method includes: fitting a plurality of fitting portions to a plurality of fitted portions, wherein each of the plurality of fitting portions is provided on the side of a first lens for collimating light emitted from a light emitting device and includes at least one of a convex portion and a concave portion and each of the plurality of fitted portions is provided on the side of a second lens for aggregating the light collimated by the first lens and has a shape to be fitted to a corresponding one of the plurality of fitting portions; and adjusting a position between the first lens and the second lens such that the light emitted from the light emitting device is aggregated into an optical fiber ferrule via the first lens and the second lens.

Inter-lens adjusting method and photoelectric hybrid substrate

A photoelectric hybrid board includes: a first board on which a circuit is formed; an optical waveguide layer stacked with the first board; a first optical waveguide section formed in a direction of stacking in the first board and the optical waveguide layer; and a concave part formed, from the optical waveguide layer side, in the optical waveguide layer in an intersection part of the optical waveguide layer and the first optical waveguide section.

Photoelectric hybrid board, information processor, and method for manufacturing photoelectric hybrid board

A plug housing for accommodating a plug for connecting to the adapter, includes a housing body having an inside surface, the inside surface forming a through hole accommodating the main body of the plug, a slope portion formed on the inside surface and configured to cause the main body of the plug to move forward by a reaction force received from a second lever formed on the side surface of the plug when the main body of the plug is accommodated in the through hole and the second lever is pushed down by the slope portion, and a restrict portion formed on the inside surface and configured to restrict the forward movement of the main body of the plug.

Plug housing and plug apparatus

A connection device includes an adapter that covers a connection target that is connected to a connector, where the adapter is secured to a connection apparatus that is provided with the connection target. The connection device includes a housing that has a cylindrical portion that holds the connector such that the connector is movable relative to the cylindrical portion in an axial direction, where the cylindrical portion is engaged with the adapter such that the connector is connected to the connection target, and a first spring that urges the connector toward the connection target.

Connection device

An optical connector has an optical-connector housing in which a ferrule at an extending end of an optical fiber is incorporated. The optical-connector housing is provided at opposite ends thereof with arm portions to abut against a housing of an electrical connector. Accordingly, the optical connector and the electrical connector are prevented from connecting to each other so that damage to the optical connector is reduced.

Optical connector

An optical connector has an optical-connector housing in which a ferrule at an extending end of an optical fiber is incorporated, the optical-connector housing having a coding-key mounting portion. A coding key is mounted at the coding-key mounting portion in a condition in which the extending end of the coding key projects further than the extending end of the ferrule.

An optical connector connecting structure capable of achieving quick and easy connection of optical connectors of different types. The optical connector connecting structure includes a holder fixed to a communication device and having a pair of optical connector holding members and an adapter insertion opening, and a first optical connector held by the optical connector holding members. The optical connector connecting structure further includes an adapter inserted through the opening of the holder and detachably mounted to the first optical connector.
