Description

本発明は、パソコンや制御機器などの電子機器に装着されたコネクター（機器側のコネクター）からの各種データの漏洩やコネクター（機器側のコネクター）の悪戯を防止するのに使用するコネクターロック装置に関する。 The present invention relates to a connector lock device used to prevent leakage of various data from a connector (connector on the device side) attached to an electronic device such as a personal computer or a control device and mischief of the connector (connector on the device side). ..

今日、パソコンの普及が急速に進み、パソコン内部にはさまざまな情報が大量に記録、蓄積されており、他面で、これらの情報を盗み出すために、パソコンへの不正アクセス、情報漏洩があとを経たない現状である。
このパソコンへの不正アクセスの中でも、近年、問題の一つになっていたのが、ＵＳＢポートへのアクセスによる情報の漏洩である。ＵＳＢポートは、周知のとおり、ＵＳＢメモリなどの外部記憶装置を接続すれば、パソコン内部のデータを簡単にコピーすることができるので、ＵＳＢポートへのアクセスを阻止する措置が必要になっている。 Today, the spread of personal computers is rapidly advancing, and a large amount of various information is recorded and accumulated inside the personal computer. On the other hand, in order to steal this information, unauthorized access to the personal computer and information leakage may occur. The current situation is that it has not passed.
Among the unauthorized access to the personal computer, one of the problems in recent years is the leakage of information due to the access to the USB port. As is well known, the USB port can easily copy the data inside the personal computer by connecting an external storage device such as a USB memory, so it is necessary to take measures to prevent access to the USB port.

そこで、本願発明者は、ＵＳＢポートに挿入ケースを差し込んでこれを塞ぎ、ＵＳＢポートの外枠の任意の面のスリットに挿入ケースに設けたロック爪を係合させることによりロックして、情報の漏洩を防止するＵＳＢポートロック装置を特許文献１により提案したところである。 Therefore, the inventor of the present application inserts an insertion case into the USB port to close it, and engages a lock claw provided in the insertion case with a slit on an arbitrary surface of the outer frame of the USB port to lock the information. Patent Document 1 has proposed a USB port lock device that prevents leakage.

ところが、近年、パソコンや制御機器などの電子機器の背面の「D-Sub（D-Subminiature）」と称されるコネクターや、「DVI（Digital Visual Interfase）」と呼ばれるコネクターからもまた、各種のデータが抜き取られることが分かってきた。
これらのコネクターはパソコンや制御機器の筐体に両端にねじ部を併設されて装備されるコネクター（機器側のコネクター）で、この機器側のコネクターにケーブル側のコネクターを接続し、このケーブル側のコネクターの両端に併設される各取付ねじを機器側のコネクター両端の各ねじ部に締結することにより機器側のコネクターとケーブル側のコネクターとの接続を固定する形式になっており、ＵＳＢポートとは異なる構造のため、上記のロック装置では対応できない。
また、これまでのところ、この種のコネクターを塞ぎロックするコネクターロック装置は存在していないものとみられる。このため、かかるコネクターロック装置と関連性を有する技術の蓄積がなく、記載すべき先行技術文献はない。 However, in recent years, various data have also been obtained from the connector called "D-Sub (D-Subminiature)" on the back of electronic devices such as personal computers and control devices, and the connector called "DVI (Digital Visual Interfase)". Has been found to be extracted.
These connectors are connectors (connectors on the device side) that are installed on the housing of a personal computer or control device with screws on both ends. Connect the connector on the cable side to the connector on the device side, and connect the connector on the cable side to this cable side. By fastening each mounting screw attached to both ends of the connector to each screw part at both ends of the connector on the device side, the connection between the connector on the device side and the connector on the cable side is fixed. What is a USB port? Due to the different structure, the above locking device cannot handle it.
Also, so far, it seems that there is no connector lock device that closes and locks this type of connector. Therefore, there is no accumulation of technologies related to such a connector lock device, and there is no prior art document to be described.

It is attached by passing the mounting screws S0 at both ends of the mounting portion through the screw insertion holes of the housing and tightening them into nuts (not shown) inside the housing. By plugging the cable-side connector K1 which is the female side connector into the D-Sub in this way, the personal computer P and the external device (not shown) are passed through the D-Sub and the cable-side connector K1. Is connected. Then, by fastening the mounting screws S1 provided at both ends of the connector K1 on the cable side to the threaded portions S at both ends of the D-Sub (threaded portions S at the head of each mounting screw S0), the D-Sub and the cable side are fastened. The connection with the connector K1 is fixed, and by doing so, even if the cable is pulled carelessly, poor contact between the D-Sub and the connector K1 on the cable side will occur, or the D-Sub will be on the cable side. The connector K1 will not come off.
DVI is one of the interface standards for connecting a personal computer and a display. As shown in Fig. 1 (d), DVI is almost the same as D-Sub, and by plugging the connector K2 on the cable side into DVI. , The personal computer P and the display (not shown) are connected via these DVI and the connector K2 on the cable side, and the mounting screws S2 attached to both ends of the connector K2 on the cable side are fastened to the screw portions S on both ends of the DVI. By doing so, the connection between the DVI and the connector on the cable side is fixed.

図６にこのコネクターロック装置ＬをDVIに用いた場合の使用例を例示している。
この場合、コネクターロック装置ＬはロックボディＢの外筒１０の部分がDVIの長手方向の寸法よりも少し小さく短手方向の寸法よりも少し大きい内径の略円筒形に形成されて、この外筒１０一端の被覆部１０１がDVIの一部を内包可能に略円筒形状に形成され、DVIの残部を被覆部１０１の外に出す（逃がす）ため被覆部１０１の外周部の一部（特殊ねじ挿通部２とは反対側の面の一部）が略コ字形に切り欠かれて、DVI通し部（コネクター通し部）１０３（図３参照）が設けられる。 FIG. 6 illustrates an example of use when this connector lock device L is used for DVI.
In this case, in the connector lock device L, the outer cylinder 10 portion of the lock body B is formed into a substantially cylindrical shape having an inner diameter slightly smaller than the longitudinal dimension of the DVI and slightly larger than the lateral dimension of the DVI. 10 The covering portion 101 at one end is formed in a substantially cylindrical shape so that a part of the DVI can be included, and a part of the outer peripheral portion of the covering portion 101 (special screw insertion) in order to let the rest of the DVI out (release) of the covering portion 101.
