Abstract

An optical connector apparatus includes a connector which is connected to an electro-optical composite cable including an optical fiber and a metal conductor, and a connection object to be connected. The connector is provided with a ferrule which has a conductive portion on at least a part of the surface thereof. The connection object to be connected is provided with an electrically conductive connection member to be connected to the ferrule. The ferrule and the cable are connected by a crimping structure. When the ferrule is inserted in the connection member, the connector and the connection object to be connected are electrically and optically connected to each other. Provided is also an optical connector apparatus which comprises a connector having a plurality of ferrules having distances between the end of the ferrules and the conductive portions so that the timing of the connection of the connector to the object to be connected is delayed, and thus the optical connector apparatus is capable of hot swapping. The connection object to be connected can be a combination of an adapter and a mating connector, or an optical element and an adapter which holds the same, etc.

First claim

The invention claimed is:

1. An optical connector apparatus having a connection member connecting ferrules, wherein the connection member is formed by processing a metal sheet having two edge portions so that the connection member has a main body having a tube or a tubular shape, the two edge portions facing each other,
wherein the main body portion comprises a plurality of ferrule-contact portions, each of the ferrule-contact portions being separated from each other on a perpendicular surface perpendicular to an axis-direction of the connection member and being brought into contact with the ferrule when the connection member holds the ferrule,
wherein the main body portion comprises three of the ferrule-contact portions positioned on the main body portion at about 120 degree intervals, and
wherein each of the contact portions has a linear shape on the perpendicular surface and extends in the axis-direction.

2. The optical connector apparatus as recited in claim 1 , wherein the main body portion has an opposed-edges portion constituted of the edge portions positioned opposite to each other, and
wherein one of the ferrule-contact portions is positioned at the opposite side of the opposed-edges portion on the perpendicular surface.

3. The optical connector apparatus as recited in claim 1 , further comprising a holder holding the connection member, wherein:
the ferrule holds the electro-optical composite cable including a metal conductor and an optical fiber in a state in which the ferrule is electrically connected with the metal conductor, and
the connection member comprises a support portion and a pair of spring portions which is brought into contact with the ferrule.

4. The optical connector apparatus as recited in claim 3 , wherein the support portion is positioned between the pair of spring portions on the perpendicular surface.
