[Industrial applications]

 The present invention is an electrical connection in which plug adapters with built-in optical / electrical converters are connected to both ends of an optical fiber cable, and electrical signals between electronic devices are communicated through the optical fiber cable via the plug adapters. The present invention relates to a plug optical connector.

[0002]

[Prior Art]

 2. Description of the Related Art Conventionally, an electrical plug optical connector for performing communication by using this kind of optical fiber cable is provided with an electrical plug 11 at both ends of an optical fiber cable 10 molded to a predetermined length, for example, as shown in FIG. A plug adapter 12 integrally connected is generally used.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional electrical plug optical connector, since the connection accuracy between the both ends of the optical fiber cable 10 and the optical / electrical converter incorporated in the plug adapter 12 is extremely delicate, the length of the optical fiber cable 10 is long. Since L0 is determined according to the distance between the electronic devices, there is a drawback that the length of the optical fiber cable 10 cannot be adjusted. In addition, it is necessary to prepare a plurality of electrical plug optical connectors with different lengths of optical fiber cables so that it can be applied even when the distances between various electronic devices are different. It was troublesome, and there were problems such as high costs.

The object of the present invention is to solve the above-mentioned conventional problems, and is constructed so that both ends of an optical fiber cable can be detachably attached to a plug adapter equipped with an optical / electrical converter. In addition, an electrical connector optical connector in which the optical fiber can be cut and the L length can be adjusted by simplifying the assembly of the ferrule and the optical fiber.

[0005]

[Means for Solving the Problems]

 In order to achieve such an object, the present invention connects a plug adapter having a built-in optical / electrical converter and equipped with an electrical plug to both ends of an optical fiber cable. In an optical connector optical connector that communicates electrical signals between electronic devices via an optical fiber cable via an optical fiber cable, attach and detach ferrules to both ends of multiple optical fiber cables of different lengths. It is characterized in that both ends of the plug can be attached to and detached from the ferrule insertion port of the plug adapter.

[0006]

[Action]

 Based on such a configuration, according to the electrical plug optical connector of the present invention, detachable ferrules are fixed to both ends of the optical fiber cable, and both ends of the optical fiber cable are connected to the optical / electrical converter. Since it is configured so that it can be attached to and detached from the ferrule insertion port of a plug adapter with a built-in connector, it is possible to improve the connection accuracy between both ends of the optical fiber cable and the optical-electrical converter built into the plug adapter, and The L length of the cable can be adjusted freely.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view showing an electrical connector optical connector according to the present invention, and FIG. 2 is a view taken along line 2-2 of FIG. In the figure, 1 is an optical fiber cable having a predetermined length LX, and 2 is a plug adapter which is attachable to and detachable from both ends of the optical fiber cable 1.

A plurality of optical fiber cables 1 having different lengths LX are prepared so that the optical fiber cables 1 can be applied even when distances between various electronic devices are different, and both ends of each of the optical fiber cables 1 are prepared. After the coating is peeled off, the ferrules 3 are fixed by a stopper (not shown).

Further, the plug adapter 2 includes an electrical connector 4 having a built-in optical / electrical converter and a ferrule insertion port 5 into which the ferrules 3 fixed to both ends of the optical fiber cable 1 are mounted. The case body of the plug adapter 2 is integrally provided with a lock piece 6 for attaching / detaching the plug adapter 2 to / from an electronic device or the like. As shown in FIG. 2, the electrical connector 4 has a plurality of electrical contacts 7 and a knock 8 for positioning when mounted on an electronic device.

Based on such a configuration, according to the embodiment of the present invention, the plug adapters 2 each having the optical / electrical converter therein and the electrical connector 4 are connected to both ends of the optical fiber cable 1. However, when the electric signal between the electronic devices is communicated by the optical fiber cable 1 through the electrical connector 4 of the plug adapter 2, the optical fiber is set to an appropriate length Lx corresponding to the distance between the electronic devices. The cable 1 is cut, the ferrules 3 are fixed to both ends of the optical fiber cable 1, the ferrules 3 are attached to the ferrule insertion ports 5 of the plug adapters 2, respectively, and then the electrical plugs of the plug adapters 2 are plugged. By inserting 4 into the electronic device, the connection between the electronic devices is established.
