Abstract

PURPOSE:To make it unnecessary to attach independent connector receptacles for electricity and light by constituting the center portion of a photoelectric receptacle of an optical fiber and a center conductor having the optical fiber as its core and formed into the shape of a cylinder. CONSTITUTION:The center conductor 12 of an electric connector plug 10 joined is positioned by a dielectric 13 and brought into contact with the end face of the center conductor 2 of a photoelectric receptacle 6. In this case, an optical fiber 1 is located slightly deeper than the end face of the conductor 2 in order to protect the end face of the fiber 1. The external conductor 14 of the plug 10 is locked by a protrusion 5 and electrically connected to a conductor 4. The ferrule 22 of an optical connector plug 20 fitted has the same diameter as the center conductor 2 of the photoelectric receptacle 6 and is therefore positioned by a dielectric 23 and brought into contact with the end face of the conductor 2 and then the fiber 1 serving as the core of the ferrule 22 is made to abut on the center conductor 12 whereby optical signals can be transmitted and received. An external conductor 24 is locked by the protrusion 5 and electrically connected to the conductor 4.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a male-female connector for mechanically connecting optical fibers and conductors, and particularly to a receptacle thereof.

[Prior art] This type of conventional technology uses an electrical connector receptacle such as a BNC to receive and transfer electrical signals, and uses an optical connector receptacle to receive and transfer optical signals. As such, separate receptors were used.

[Problems to be Solved by the Invention] In conventional technology, electrical connector receptacles handle electrical signals and optical connector receptacles handle optical signals separately, so in the case of equipment that handles both electrical signals and optical signals, The electrical connector receptacle and the optical connector receptacle must be installed separately, which has the drawback of increasing the mounting area of the connector.

Therefore, it is an object of the present invention to provide a connector receptacle, also called a photoelectric connector receptacle, which can be connected to either an electrical connector plug or an optical connector plug.

[Means for Solving the Problems] According to the present invention, a central portion having at least one of an optical fiber and an electric conductor, a cylindrical conductor coaxially surrounding the central portion, and a cylinder coaxially surrounding the dielectric. A photoelectric/electronic receptacle is obtained in which the central portion is comprised of an optical fiber and a central conductor formed in a cylindrical shape with the optical fiber as a core.

[Example] Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a sectional view and a front view of a photoelectric receptacle according to an embodiment of the present invention. FIG. 2 is a cross-sectional view when the photoelectric receptacle of the present invention is fitted with an electrical connector plug, and FIG. 3 is a cross-sectional view when the photoelectric receptacle of the present invention is fitted with an optical connector plug.

In FIG. 1, a central conductor 2 including an optical fiber 1, a dielectric 3. Since the grounded external conductor 4 forms a coaxial line, it is possible to receive and transmit high frequency electrical signals.

The protrusion 5 is used to lock an optical connector or an electrical connector when mated.

In FIG. 2, the center conductor 12 of the mated electrical connector plug 10 is positioned by the dielectric 13 to contact the end surface of the center conductor 2 of the optoelectronic receptacle 6. In FIG. In that case, the optical fiber 1 is located about 5 μm deeper than the end face of the central conductor 2, although not shown in the drawings, in order to protect the end face. The outer conductor 14 of the electrical connector plug 10 is locked by the protrusion 5 and electrically connected to the outer conductor 4.

In FIG. 3, since the ferrule 22 of the fitted optical connector plug 20 has the same diameter as the center conductor 2 of the photoelectric receptacle 6, it is positioned by the dielectric 23 and comes into contact with the end surface of the center conductor 2. After, ferrule 22
The optical fiber 21 forming the core of the photoelectric receptacle 6 and the optical fiber 1 of the photoelectric receptacle 6 are brought into abutting state, and optical signals can be received and transferred. The outer conductor 24 is locked by the protrusion 5.

It is electrically connected to the external conductor 4.

[Effects of the Invention] As explained above, the photoelectric connector receptacle of the present invention can transmit and receive both electricity and light by fitting with either an electrical connector plug or an optical connector plug, so it can transmit both electrical signals and optical signals. In the case of equipment, it is not necessary to separately install both electrical and optical connector receptacles, which has the effect of reducing the mounting area of the connector.
