Provided is an optical connector apparatus comprising 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.

In an electric connector having a first end and a second end opposite to the first end, an insulator supports conductive contacts including signal contact pairs and ground contacts. Each of the signal contact pairs includes a pair of the conductive contacts. At the first end, the signal contact pairs and the ground contacts are arranged in a first and a second row, respectively, which are parallel to each other and extend in a first direction. At the second end, the signal contact pairs and the ground contacts are arranged in a single row so that each of the ground contacts are interposed between each of the signal contact pairs on the first row at the first end and each of the signal contact pairs on the second row at the first end.

A connector to be mounted to a board includes a contact having an angled portion, a housing having a fitting portion and fixedly holding the contact, and a conductive shell. The shell includes a front shell covering the fitting portion and a back shell covering the angled portion. The front shell has a terminal to be connected to the board and a fixing portion provided with an insertion hole allowing a screw to be inserted therethrough. The back shell has a terminal to be connected to the board and a fixed portion faced to the fixing portion. The fixed portion has a tap portion. The front and the back shells are fixed to the housing by screwing the screw through the insertion hole into the tap portion.

A connector includes contact portions of signal contacts that are provided in pairs and contact portions of ground contacts arranged in a row in a contact arrangement direction that is orthogonal to a housing fitting direction. The respective contact portions of each of the pairs of signal contacts are disposed between the contact portions of the ground contacts adjacent in the contact arrangement direction. The connection portion of one of the signal contacts of each pair and a first connection portion of each ground contact are alternately arranged in a row in the contact arrangement direction. The connection portion of the other of the signal contacts of the pair and a second connection portion of each ground contact are alternately arranged in a row in the contact arrangement direction.

A connector comprises a plurality of ground contacts, a housing, a coupling portion, and a second connection portion. The ground contacts are provided with first connection portions, respectively, which are to be connected to drain lines of first cables, respectively. The housing holds the ground contacts so that each of the ground contacts extends along a first direction. The coupling portion is formed integrally with the ground contacts. The coupling portion couples the ground contacts so that the ground contacts are arranged in a second direction perpendicular to the first direction. The second connection portion is formed integrally with the coupling portion. The second connection portion is configured to be connected to a large-diameter line of a second cable different from the first cables. The second connection portion extends along the first direction and is larger than the first connection portion in the second direction.

A connector is provided which makes it possible to have the soldered states of contacts thereof checked or have itself removed with ease. A row formed by terminal portions of first and second signal contacts and terminal portions of ground contacts is disposed rearward in the fitting/removing direction with respect to rows formed by terminal portions of contacts for non-high-speed transmission. The terminal portions of contacts for non-high-speed transmission are disposed between the contact portions and terminal portions of the first and second signal contacts and the ground contacts. The terminal portions of the first and second signal contacts and the terminal portions of the ground contacts are formed to have a surface-mount type planar shape. The terminal portions of the contacts for non-high-speed transmission are each formed to have a through hole insertion-type pin shape.
