Description

Hybrid electro-optical connector {hybrid electro-optical connector}

The present invention relates to a composite photoelectric connector, and more particularly, to a composite photoelectric connector that is miniaturized and has improved transmission quality of an optical signal.

In general, an optical connector is an optical communication component for connecting optical fibers to each other. In particular, it can transmit information safely without being affected by the external environment, and it can accurately guide to a designated location while minimizing the loss of transmitted information. It is widely used in the mining industry. In addition, recently, with the rapid development of informatization, the frequency of utilization of optical communication is increasing in the fields of ships, military, aviation, automobiles, and robots.

Meanwhile, FIG. 1 is an exemplary view showing a conventional composite photoelectric connector.

As shown in FIG. 1, the conventional electro-optical connector (1, electro-optical connector) includes a wire accommodating part (2) accommodating wires and an optical fiber accommodating part (3) accommodating optical fibers. include Here, the wire accommodating part 2 includes a plurality of wire connectors 2a, and the optical fiber accommodating part 3 includes a plurality of optical connectors 3a.

Also, the wire accommodating part 2 is disposed on one side of the photoelectric connector 1, and is disposed in a form in which the wire connectors 2a are clustered. In addition, the optical fiber accommodating part 3 is disposed on the other side of the photoelectric connector 1 spaced apart from the electric wire accommodating part 2, and each optical connector 3a is disposed adjacent to each other while being spaced apart from each other.

At this time, the conventional optical fiber accommodating part 3 minimizes the structure inside the photoelectric connector 1 and is disposed adjacent to each other so as to be easily distinguished from the area where the electric wire accommodating part 2 is formed.

However, in the conventional photoelectric connector 1, each of the optical connectors 3a is spaced apart, but a shield is not disposed between each of the optical connectors 3a, making it difficult to secure insulation and mutual interference between optical fibers. There was a problem that the transmission quality was degraded.

In particular, in order to miniaturize the photoelectric connector, the distance between each of the optical connectors 3a should be further reduced, but since the distance is reduced, it is more difficult to secure insulation, so there is a problem in that miniaturization and insulation cannot be satisfied at the same time.
