Description of the Invention (i) [Technical Field to which the Invention belongs] The present invention relates to various AV devices or data transmission devices, which are provided with digits for inputting and outputting processing. The socket of the optical connector of the signal element, especially the socket of the optical connector used for connecting with the plug of the square type optical connector. [Known technology] The socket of this optical connector is to insert the optical connector plug into its plug insertion hole to perform the optical connection between the light receiving element or the light emitting element held by the former and the plug. The communication can achieve the intended purpose, but when the plug is not inserted, that is, how to close the plug insertion hole when not in use has always been a problem. If the plug insertion hole is left open when not in use, dust or other foreign matter cannot be prevented from intruding into it, and dirt will adhere to the optical element held inside, which will reduce the light transmission efficiency. However, it may be impossible to transmit a predetermined optical signal. Therefore, a structure was first adopted in which the plug insertion hole was sealed by inserting a protective cap. However, when the opening is closed with a protective cover when not in use, the protective cover must be removed when inserting the plug of the optical connector, and the protective cover must be inserted again after removing the plug. Therefore, the operation was very troublesome, and there was also the problem of the storage protection cover when the plug was inserted. Later, a structure in which a freely openable and closable baffle was arranged in the opening of the plug insertion hole was adopted. The above-mentioned baffle was initially opened to the outside. In this way, although there is no problem to protect the protective cover when inserting the plug into the plug insertion hole, (please read the precautions on the back before filling this page)

Description of invention (2) However, when inserting and removing the plug, there will be other operations that must be used to make The problem of the opening and closing of the baffle was later adopted by an inwardly opened baffle that resolved the problem. The baffle has a structure that is spring-biased by a spring provided on a hinge shaft provided on one side thereof. When the plug is inserted, the baffle is pressed and opened due to its insertion action. When the plug is unplugged, as long as the bezel is unplugged, it will automatically close. There is no need to perform a special operation for opening and closing the shutter, and the problems such as the need for other opening and closing operations to open the shutter to the outside are eliminated. In this way, the problem of closing when the insertion hole is not used is solved by arranging a baffle that opens inwardly at the opening portion, but the baffle that opens inward is interposed through the hinge shaft. Opening and closing are freely arranged on the upper part of the opening, so it will be difficult to close the guide grooves of the insertion guide protrusions corresponding to both sides of the plug formed by the opening, and it is necessary to close the upper and lower cards of the plug. The locking recesses on the inner and upper portions of the stopper are formed on the front face of the baffle. Therefore, particularly when a plug is inserted and removed, excessive force is applied to a hinge shaft supporting the baffle. In order to avoid this problem, a baffle was developed in which the hinge shaft is arranged on the side of the opening to open laterally. Thereby, a protruding portion for closing the guide groove is formed on the side portion of the baffle plate, and the plug insertion hole can be completely closed when not in use, so there is no need to lock the protruding portion on the upper part of the plug. A locking recess is formed on the front surface of the baffle. The socket of this optical connector is mainly for the repeated improvement of the means used to close the opening of the plug insertion hole when not in use.
