Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pin plug type connector suitable for connecting electronic devices in constructing, for example, an audio system in which both digital signals and analog signals are used. For those that were made to be able to transmit both.

[0002]

[Prior art]

 Conventionally, when connecting electronic devices, etc., in a system in which signal transmission from one side to the other side is selectively performed by either an optical signal or an electrical signal, As shown in FIG. 2, it has, for example, a multi-pole contact portion composed of three contact portions 51, 52, 53 for receiving an electric signal (analog signal) and an optical signal receiving portion 57 for receiving an optical signal (digital signal). If the female connector 50 having the shape of a pin jack is provided and the signal to be transmitted is an electric signal, the multipolar plug type connector 20 is inserted into the female connector 50, and if the signal to be transmitted is an optical signal. The pin plug type optical connector 30 having the optical fiber 22 therein is inserted into the female connector 50.

[0003]

[Problems to be solved by the device]

 However, it goes without saying that the above-mentioned two types of connectors 20 and 30 can transmit only one of the electric signal and the optical signal, and it is impossible to transmit them at the same time. Even if it is not necessary to transmit the signal at the same time, it is necessary to replace the connectors 20 and 30 according to the signal to be transmitted as described above, which is troublesome and the connector may be used in the wrong type. there were.

In view of the above point, the present invention can transmit both optical signals and electric signals without the need to replace two types of plugs, and therefore, it is troublesome when connecting electronic devices and the like. It is an object of the present invention to provide a pin plug type connector that can eliminate the need for the connection and prevent misconnection.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the pin plug type connector according to the present invention is characterized in that an optical fiber is internally provided in a multipolar plug made of metal.

[0006]

[Action]

 The pin plug type connector according to the present invention configured as described above is attached to the end of a composite cable including a plurality of electric wires and an optical fiber cable, and is a metal multi-pole located on the outer peripheral side. A plurality of electric wires are connected to the plug in a known manner, and an optical fiber is axially passed inside the multipolar plug.

By doing so, it becomes possible to transmit both the electric signal and the optical signal at the same time, and even when it is not necessary to transmit the optical signal and the electric signal at the same time, the conventional transmission is performed. Since it is not necessary to replace the two types of connectors depending on the signal to be used, it is possible to save time and effort when connecting electronic devices and to prevent erroneous connections.

[0008]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an embodiment of a pin plug type connector according to the present invention.

The pin plug type connector 10 of this embodiment is one in which a plurality of electric wires 1, 2 and 3 are attached to the end of the composite cable 7 arranged on the outer circumference of the optical fiber cable 4, and is located on the outer circumference side. The electric wires 1, 2 and 3 are connected to the metal multi-pole plug 12 as will be described later, and the optical fiber 5 is passed inside the multi-pole plug 12 along the axial direction. A cylindrical resin mold 15 is attached so as to cover the outer circumference of the connection portion between the composite cable 7 and the composite cable 7.

The multipolar plug 12 is divided into three parts along the axial direction by an insulating material 16. The tip part 12a is for Vcc (+ power source), the center part 12b is for signal, and the rear end part 12c is GND. The electric wires 1, 2, and 3 of the composite cable 7 are connected to them, respectively, by sandwiching.

In the pin plug type connector 10 of the present embodiment having such a configuration, if it is inserted into the female connector 50 described above, both an electrical signal (analog signal) and an optical signal (digital signal) can be obtained. It is possible to transmit at the same time.

Further, even when it is not necessary to transmit an optical signal and an electric signal at the same time, it is not necessary to replace the two types of connectors according to the signal to be transmitted as in the conventional case, so that electronic devices can be connected to each other. This saves time and effort when connecting and prevents erroneous connections.

[0013]

[Effect of device]

 As can be understood from the above description, the pin plug type connector according to the present invention is to be attached to the end of a composite cable composed of a plurality of electric wires and an optical fiber cable, and is made of a metal located on the outer peripheral side. Since multiple wires are connected to the multi-pole plug and an optical fiber is installed inside the multi-pole plug along the axial direction, it is possible to transmit both electrical signals and optical signals at the same time. Becomes Even when it is not necessary to transmit optical signals and electrical signals at the same time, it is not necessary to replace the two types of connectors according to the signals to be transmitted as in the conventional case. Therefore, when connecting electronic devices, etc. This saves time and effort and prevents incorrect connections.
