Description of the Invention: [Technical Field of the Invention] The present invention relates to a medium for transmitting a medium such as an electrical signal cable and an optical fiber. [Prior Art] As an electric power storage device, it is known that the following components and peripheral walls are provided; the optical signal terminal at a desired position of the peripheral wall provided inside the casing is disposed at the optical signal terminal, and the connector is disposed. Insertion port, media conversion connector is inserted into the connector insertion port [Patent Document] Patent Document 1: 曰本特开 [Content of the Invention] [Problems to be Solved by the Invention] In the media converter, unnecessary power consumption is used The purpose of reducing the invention is to provide a provider. [Means for Solving the Problem] The media converter of the present invention, the electronic circuit board of the unit, and the optical signal terminal and the electrical signal end body converter are provided, and the medium converter cable is used to connect different types and optical fibers. The connected media: the outer casing has a bottom wall, a top electronic circuit board; and a sub- and electrical signal terminals. The optical element and the light-receiving element are connected to the external wiring by the external connection means'. 2008 — 1225 14 Bulletin The light-emitting element is always on, so this power consumption is a problem. A media conversion system for reducing power consumption includes a casing and a required position of the casing built in the peripheral wall of the casing. The media converter is characterized in that the 201230703 further has a detecting means for detecting whether the external connecting means is connected to the optical signal terminal or The electrical signal terminal is connected; and the power source control means is configured to connect the light-emitting element when the external connection means is connected, and to prevent the light-emitting element from being turned on when the external connection means is not connected. The external connection means is a connector such as a fiber optic cable (p〇F) connected to it. In this case, the connector plug-in population is formed externally, and the light-emitting element and the light-receiving element of the optical signal terminal are disposed to face the front end surface of the connector, and the detecting means is disposed to face the connector insertion opening, and the detecting means detects the outside. Whether the connection means is connected to the optical signal terminal. Whether or not the external connection means is connected, or an electrical signal terminal can be used. In this manner, the detection means can be arranged so as to face the electronic signal for the 盥 LAN, for example, the corresponding μ insertion. 1 The detecting means is, for example, a micro-switch. In this case, when the connector is not inserted, the micro-switch is set to be non-conductive, and the micro-switch is pressed by the side of the connector to make the micro-switch non-conductive. Instead of a microswitch, a photo sensor, a proximity sensor, or the like can also be used. In any case, the detecting means is configured to detect the presence or absence of an external connection means, and output the detection result (with or without a connection signal) to the power supply control means. The person recognizes that the power source control means is constituted by, for example, a microcomputer or the like, and has a function of switching the power from the battery provided in the media converter to each member: the switching function of turning on/off is determined based on whether or not the connection from the detecting means is present. The signal causes the light-emitting element to become conductive or non-conductive. According to the media converter of the present invention, since the light-emitting element is rendered non-conductive without connecting the external connection means, power consumption can be reduced, and the life of the -4 - 201230703 optical element becomes long. Further, in the state in which the light-emitting element is turned on and the external connection means is connected, there is a possibility that an advanced person's eyes from the light-emitting element may be present, but this situation can be prevented and the safety can be improved. [Effects of the Invention] The media converter according to the present invention further includes: detecting means for detecting whether the external connection means is connected to the optical signal terminal or the electrical signal terminal; and the power source control means is connected to the external material connection means In the case of 'the light-emitting element is set to (4)' and the light-emitting element is made non-conductive when the external connection means is connected; therefore, the power consumption can be reduced, and the life of the light-emitting element can be made longer" and the light-emitting element can be made Non-conducting 'security is improved. [Embodiment] Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in Fig. 1, a third embodiment of the media converter of the present invention includes a synthetic resin casing (2) having a bottom wall (2a), a top wall (not shown), and a peripheral wall (2b). a substantially square electronic circuit board (3) disposed inside the casing (2); an optical signal terminal (4), an electrical signal terminal (5), a light emitting diode (6), and a connector insertion opening (7) It is placed at the desired position of the peripheral wall (2b), and the micro-switch (detection means) (8)' detects whether the connector (1 〇) with the optical fiber cable (1 〇a) as an external connection means is light. The signal terminal (4) is connected; and the power control means (9) receives the conduction and non-conduction signals from the microswitch (8) to make the light-emitting element (4a) of the media converter (1) conductive and non-conductive. . The optical signal terminal (4) is opened to the outside through the connector insertion opening (7) and has a light-emitting element (4a) and a light-receiving element (4b), which are arranged to be inserted into the connector insertion opening (7). The front end faces of the connectors (1〇) are opposed to each other. An electrical signal cable for LAN is connected to the electrical signal terminal (5)'. The microswitch (8) faces the connector insertion opening (7) in such a manner as to be pushed by the side of the connector (10) into which the connector insertion opening (7) is inserted. When the connector (10) is connected to the media converter (丨) (the connector (1〇) is inserted into the position shown by the two-dot chain line in Fig. 1), the microswitch (8) becomes conductive. The power supply control device thereby turns on the light-emitting π-piece (4a) of the media converter (1). Therefore, the optical fiber cable (1〇a) is in a state of being connectable to the electrical signal electron microscope via the media converter (1). In the case where the connector (10) is not connected to the media converter (丨) (the connector (10) is pulled out to the position shown by the solid line in Fig. 1), the microswitch (8) becomes non-conductive, and The power supply control means (9) accordingly causes the light-emitting element (4a) of the medium converter (i) to become non-conductive. Therefore, in the case where the connector (1〇) is not inserted, the light-emitting element (4a) is rendered non-conductive, and power consumption can be reduced. Further, when the light-emitting element (4a) is turned on and the connector (1) as the external connection means is not inserted, light emitted from the light-emitting element (4) is irradiated through the connector insertion opening (7). The possibility of entering the human eye to the outside, but in the case where the connector (1〇) is not connected, the safety of the situation can be prevented by setting the light-emitting element (4a) to be non-conductive. Although the micro switch (8) is used to detect the presence or absence of the insertion connector (10), it may be replaced by a photo sensor, a proximity sensor, etc. Alternatively, the micro switch (detection means) may be used. (8) Disposed in the vicinity of the electrical signal terminal (5) to detect whether the connector (10) of the supplied electrical 201230703 signal cable as an external connection means is connected to the electrical signal terminal (5). [Industrial Applicable By using the media converter of the present invention to connect the electrical signal cable to the optical fiber cable, communication that reduces power consumption can be realized, and the performance of optical communication can be improved. [Simplified Schematic] A front view of the first embodiment of the media converter of the present invention is schematically shown.
