Description

Optical connector and its cable {OPTICAL CONNECTOR AND CABLE THEREOF}

The present invention relates to an optical connector and its cable structure, and more particularly, to an optical connector and its cable structure used for special applications such as medical devices.

Numerous types of light source systems are used to transmit light from high intensity light sources, such as arc lamps, to light paths including a single optical fiber or bundle of optical fibers made of a light conducting material such as glass or plastic, to reach other devices. do. Light transmitted by optical fibers is used for various industrial, commercial and medical purposes. For example, light transmitted by optical fibers is used for a variety of medical purposes, including surgical lights, headlamps, endoscopes or related surgical devices such as borescopes.

For example, referring to the endoscope, the endoscope is connected to the light source system through an optical fiber optical guide coupled to the light source system by a proximity connector. The optical fiber light guide is an optical fiber bundle or a single optical fiber. In general, proximity connectors are configured to be removable from the light source system to increase the ease of use of the lighting device. For example, the same light source system can be used with different multiple lighting devices.

Prior-type proximity connector systems include fixed adapters, turret adapters, and general purpose adapters. However, these conventional proximity connectors are bulky and heavy. When the conventional proximity connector is removed from the light source system, if the weight of the proximity connector is not carefully considered and handled, there is a problem in that stress is applied to the optical fiber optical guide and stress is accumulated in the optical fiber optical guide.

In addition, the optical fiber optical guide is placed in the center for the most concentration of light, and the optical fiber optical guide is coated with rubber or silicon, and then the electric wire for supplying power for an endoscope snap camera or the like is placed outside. Coating with a flexible coating such as a flexible stainless coating. When connecting such a device to the endoscope through the proximity connector, connect the connector of the optical fiber optical guide (proximity connector) to the main body with the light source, and separate the wires such as the power line and the video signal line from the front end of the connector and connect them to the other side of the main body It was. When connected in this way, the electric wire of weak durability is broken. In this way, when the wire is broken, the connector itself can not be used, or when using it, there is a problem in that the signal quality between the main body and the medical device falls.

In addition, since electric wires such as video signal lines are under the outermost sheath, when the sheath is damaged, the electric wire ages and is easily broken.

An object of the present invention has been made to solve the above-mentioned problems, the optical connector and together with the optical connector to provide a power supply and a signal line to the connector, and the optical connector comprising a plurality of such wires in the optical fiber inside the optical cable and It is to provide a cable structure.
