Optical connector

This connector () is provided with a locking member (), a receiving part (), an additional elastic part () and a pressing member (). The locking member () comprises a supporting part () and a locking part (). A mating-side connector () is provided with a mating-side locking part () and an abutting part (). In the fitted state, the locking part () applies backwards force on the mating-side locking part () with the elasticity of the supporting part (). The abutting part () is positioned in front of the receiving part (), is pressed against the receiving part (), and is restricted from moving backwards by the receiving part (). When the pressing member () is in a first position, the additional elastic part () is interposed between the supporting part () and the pressing member (), presses down the supporting part (), and maintains pressing of the locking part () against the mating-side locking part (). In this way, in the fitted state, even when an outside force in the fitting direction is applied to the connector () or the mating-side connector (), the connector () does not move in the fitting direction relative to the mating-side connector ().

Connector device

Connector

A connector device comprises a connector and a mating connector. Under a mated state where the connector and the mating connector are mated with each other, the mating connector is positioned forward of the connector in a front-rear direction. The connector comprises at least one supporting portion, at least one lock portion and a receiving portion. The mating connector has at least one mating lock portion and an abutment portion. At least one of the lock portion and the mating lock portion has an intersecting surface which intersects with both the front-rear direction and a perpendicular direction. Under the mated state, the abutment portion is positioned forward beyond the receiving portion in the front-rear direction and is brought into abutment against the receiving portion by a rearward force so that a rearward movement of the abutment portion beyond the receiving portion is regulated by the receiving portion.

A connector includes a cable holding portion, a first holding member having a first male screw portion and a first guide portion, an optical connector, an optical module, a second holding member having a second male screw portion and a second guide portion, and a coupling nut having a female screw portion. In cooperation with each other, the first and second guide portions allow a relative movement of the first holding member with respect to the second holding member in the front-rear direction while regulating a relative movement of the first holding member with respect to the second holding member in a circumferential direction about an axis parallel to the front-rear direction. Relative positions of the first holding member and the second holding member in the front-rear direction are maintained by the female screw portion being meshed with both of the first and the second male screw portions.

A plurality of optical fiber groups are housed in an optical fiber cable and which of the optical fiber groups optical fibers, which constitute the optical fiber groups, belong to can be identified depending on a covering of the optical fibers. Each of optical connectors (plug, receptacle) which are respectively attached to both ends of the optical fiber cable has regions, in which insertion holes in which the optical fibers are inserted and fixed one by one are formed to be arranged in a predetermined interval, in the same number as the number of the optical fiber groups, and even though the optical fibers in one optical fiber group are inserted and fixed in the insertion holes in an identical region, an arrangement order of the optical fibers in the region of the optical connector provided on one end is not maintained as an arrangement order of the optical fibers in the region of the optical connector provided on the other end.

A plug connector is provided with a photoelectric conversion portion, a first electric connector and a first lock portion. The first electric connector inputs and outputs electric signals into and from the photoelectric conversion portion. The first lock portion and the first electric connector are apart from each other by a first distance. A receptacle connector is provided with a second lock portion and a second electric connector. When the plug connector and the receptacle connector are mated with each other, the second lock portion engages with the first lock portion, and the second electric connector is connected to the first electric connector. The second lock portion and the second electric connector are apart from each other by a second distance. A difference between the first distance and the second distance is equal to or less than an effective contact length between the first electric connector and the second electric connector.

Connector device and plug connector

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.
