以下の図面において、同じ対象物は同じ参照符号で示されている。キーに関して、開口若しくはキー孔２ｄと共同作用する器具が次に述べるように一般に理解される。   In the following drawings, the same objects are denoted by the same reference numerals. With respect to the key, an instrument that cooperates with the opening or key hole 2d is generally understood as described below.

図１は、内部空間１ａ、ハウジング１ｂ及び電気的接続部材又はスイッチ部材１ｃを有するソケット１を示す。このソケット１は、通常の規格化された構成要素である。図示のソケット１は、ＲＪ−４５プラグ接続の構成要素である。このソケット１の図示された構成は一般に知られている。このソケット１は、例えば、嵌合式固定開口として機能する４つの開口１ｅを備えた前板１ｄにはめ込まれる。このソケットでは、図示されていない接続箱の中にラック及び引き込み部分が配置できる。   FIG. 1 shows a socket 1 having an internal space 1a, a housing 1b and an electrical connection member or switch member 1c. The socket 1 is a normal standardized component. The illustrated socket 1 is an RJ-45 plug connection component. The illustrated configuration of the socket 1 is generally known. For example, the socket 1 is fitted into a front plate 1d having four openings 1e that function as fitting-type fixing openings. In this socket, a rack and a lead-in portion can be arranged in a connection box (not shown).

上記ソケット１の前に安全装置２が配置され、この安全装置はカラー状のハウジング２ａを有する。このハウジング２ａには、上記ソケット１の方向に突出した４つの嵌合式固定具２ｃが固定的に接続されている。このハウジング２ａは、その内部にプラグ３用の案内具２ｂを有する。更にこのハウジング２ａは、その下部にキー用の開口若しくはキー孔２ｄを有する。
図１（ａ）の前面図は、図１に示されたハウジング２ａが開口２ｆと窪み２ｅとを有することを示している。 A safety device 2 is arranged in front of the socket 1, and this safety device has a collar-shaped housing 2a. Four fitting-type fixtures 2c protruding in the direction of the socket 1 are fixedly connected to the housing 2a. The housing 2a has a guide 2b for the plug 3 therein. Further, the housing 2a has a key opening or key hole 2d in the lower part thereof.
The front view of FIG. 1 (a) shows that the housing 2a shown in FIG. 1 has an opening 2f and a recess 2e.

上記嵌合式固定具２ｃは、上記前板１ｄの嵌合式固定開口１ｅに差し込むことが可能であり、これにより、図２に示すように安全装置２がソケット１に固定的に接続される。プラグ３はプラグ接点３ａと、当接部を有する開錠舌状部材３ｂとを有する。このプラグ３は、ケーブル４に接続されている。更に図２は、上記プラグ３が安全装置２即ちソケット１に差し込まれる直前の該プラグ３の姿勢を示す。このプラグ３がソケット１に差し込まれると、図６，７の縦断面図に示すように，上記開錠舌状部材３ｂが公知の方法でソケット１に配置された係止突起１ｆに食い込んで係止する。それによって、上記プラグ３は確実にソケット１に保持される。図６に見られるように、上記係止突起１ｆとの結合は、上記開錠舌状部材３ｂを押圧することによって再び解除され、プラグ３はソケット１から引き出される。   The fitting-type fixture 2c can be inserted into the fitting-type fixing opening 1e of the front plate 1d, whereby the safety device 2 is fixedly connected to the socket 1 as shown in FIG. The plug 3 includes a plug contact 3a and an unlocking tongue-shaped member 3b having a contact portion. The plug 3 is connected to the cable 4.

図７の縦断面図から分かるように、上記プラグ３がソケット１に接続される場合、上記開錠舌状部材３ｂが完全にハウジング２ａの内部に配置されるように、該ハウジング２ａは開錠舌状部材３ｂに関連して適切に形成されている。それによって該開錠舌状部材３ｂは、直接外部から接近できず、またそれと共に直接外部から操作できない。   As can be seen from the longitudinal sectional view of FIG. 7, when the plug 3 is connected to the socket 1, the housing 2 a is unlocked so that the unlocking tongue 3 b is completely disposed inside the housing 2 a. It is appropriately formed in relation to the tongue-like member 3b. Thereby, the unlocking tongue-like member 3b cannot be directly accessed from the outside and cannot be operated directly from the outside.

図３は、ソケット１に接続されたプラグ３を示す。移動方向５ａに沿ってキー５が安全装置２のキー孔２ｄに差し込まれる。このキー５は、キー主爪５ｂ、結合軸５ｃ、軸受け部５ｄ、結合部５ｅ及び握り５ｆを有する。上記キー孔２ｄ及び／又はハウジング２ａの表面に配置された軸受け部分２ｈが軸受けを形成し、この軸受けに上記キー５が軸５ａを中心に回転できるように支持される。   FIG. 3 shows the plug 3 connected to the socket 1. The key 5 is inserted into the key hole 2d of the safety device 2 along the moving direction 5a. The key 5 has a key main claw 5b, a coupling shaft 5c, a bearing portion 5d, a coupling portion 5e, and a grip 5f. The key hole 2d and / or the bearing portion 2h disposed on the surface of the housing 2a form a bearing, and the key 5 is supported by the bearing so as to be rotatable around the shaft 5a.

図４は図３による配置を示すが、上記キー５が安全装置２に完全に差し込まれている。図８は、ハウジング２ａ内部にあるキー主爪５ｂの姿勢を縦断面図で示すものである。このキー主爪５ｂが開錠舌状部材３ｂの下に置かれ、キー５つまり該キー主爪３ｂの回転によって図９に示すように開錠舌状部材３ｂが押し上げられたとき、係止突起１ｆと当接部３ｂとの間の結合が解除され、ケーブル４のプラグ３をソケット１から引き出すことができるように、キー孔２ｄが安全装置２に配置されている。上記窪み２ｅの高さは、プラグ３を後ろに引く場合に上記開錠舌状部材３ｂを妨害しないように、該開錠舌状部材３ｂの姿勢に関連してそれに適合している。内部縁２ｍは、係止突起１ｆを含めて開錠舌状部材３ｂのための更なる当接部分として使用されるように形成できる。
図５は、図４による配置を示すが、部分的に上記キー５を回転させている。 FIG. 4 shows the arrangement according to FIG. 3, but with the key 5 fully inserted into the safety device 2. FIG. 8 is a longitudinal sectional view showing the posture of the key main claw 5b inside the housing 2a. When the key main claw 5b is placed under the unlocking tongue member 3b and the unlocking tongue member 3b is pushed up by the rotation of the key 5, that is, the key main claw 3b, as shown in FIG. The key hole 2d is arranged in the safety device 2 so that the connection between 1f and the contact portion 3b is released and the plug 3 of the cable 4 can be pulled out from the socket 1. The height of the recess 2e is adapted to the position of the unlocking tongue 3b so as not to obstruct the unlocking tongue 3b when the plug 3 is pulled backwards. The inner edge 2m can be formed to be used as a further abutment for the unlocking tongue 3b including the locking projection 1f.
FIG. 5 shows the arrangement according to FIG. 4, but the key 5 is partially rotated.

図１０は安全装置２におけるハウジング２ａの異なる実施例を前面図で示し、図１１は斜視図で示す。図１に示す安全装置２とは異なって、これは保持部２ｎを有し、そこに中子２ｉが方向Ａに沿って移動することにより差し込み可能である。図１２（ａ），１２ｂ及び１２ｃに示された３つの中子２ｉの夫々が、空所２ｌを備えた様々な形態のキー孔２ｄを有する。更に、これらの中子２ｉは突出した鼻状の突起２ｋを有する。これらの中子２ｉは、上記保持部２ｎに差し込むことができる。その結果、キー孔２ｄが軸受け部分２ｈの側にくることになり、上記鼻状突起２ｋは貫通部２ｇ内に位置する。図１４（ａ）、１４ｂ及び１４ｃはキー主爪５ｂを示し、これは本質的に水滴状に伸び、上記開錠舌状部材３ｂに作用する表面とキー副爪５ｇとを有する。上記キー５は、図１２（ａ），１２ｂ，１２ｃに示されたキー孔２ｄに対応する適切な形に形成され、キー孔２ｄを有する中子２ｉと、キー主爪５ｂ及びキー副爪５ｇを有するキー５とが夫々対になるように構成されている。好ましい態様では、対になった中子２ｉとキー５とが同じ特徴を備え、好ましくは同じ色で特徴づけられる。従って、中子２ｉとそれに付属するキー５とが、同じ色のプラスチックから製造できる。着色された中子２ｉの鼻状突起２ｋが貫通部２ｇ内に配置され、それによって安全装置２の前面から見て色が認識できることが、図１０から理解される。従って、同じ色のキーを選択するだけでよく、そのキー５でプラグ接続を分離することができる。このため、多様なキー５を有する安全装置２（複数）が簡単な方法で装備できる。また、図１乃至９に示す安全装置２は、多様に形成されたキー孔２ｄを具備でき、従って、プラグ接続を分離するためには、対応する多様に形成されたキー５が必要である。また、これらの安全装置２とキー５とは、色のような特徴を備えることもできる。   10 shows a different embodiment of the housing 2a in the safety device 2 in a front view and FIG. 11 in a perspective view. Unlike the safety device 2 shown in FIG. 1, it has a holding part 2 n into which the core 2 i can be inserted by moving along the direction A. Each of the three cores 2i shown in FIGS. 12 (a), 12b and 12c has various types of key holes 2d provided with a space 2l. Further, these cores 2i have protruding nose-like protrusions 2k. These cores 2i can be inserted into the holding part 2n. As a result, the key hole 2d comes to the bearing portion 2h side, and the nose-like protrusion 2k is located in the through portion 2g. 14 (a), 14b and 14c show a key main claw 5b, which essentially extends in the form of a water droplet and has a surface acting on the unlocking tongue 3b and a key sub claw 5g. The key 5 is formed in an appropriate shape corresponding to the key hole 2d shown in FIGS. 12 (a), 12b, and 12c, and includes a core 2i having the key hole 2d, a key main claw 5b, and a key sub claw 5g. The key 5 having the key is configured to be paired with each other. In a preferred embodiment, the paired core 2i and key 5 have the same characteristics and are preferably characterized by the same color. Therefore, the core 2i and the key 5 attached thereto can be manufactured from the same color plastic. It can be seen from FIG. 10 that the nose-like protrusion 2k of the colored core 2i is arranged in the penetration part 2g so that the color can be recognized when viewed from the front of the safety device 2. Therefore, it is only necessary to select a key of the same color, and the plug connection can be separated by the key 5. For this reason, the safety device 2 (plurality) having various keys 5 can be equipped in a simple manner. Further, the safety device 2 shown in FIGS. 1 to 9 can include variously formed key holes 2d, and therefore, in order to separate the plug connection, the corresponding variously formed keys 5 are required. Also, the safety device 2 and the key 5 can be provided with features such as colors.

図１３は、キー主爪５ｂとキー副爪５ｇ、軸５ｃ、軸受け部５ｄ、結合部５ｅ及び握り５ｆを有するキー５の平面図である。
有利な態様において、安全装置２はパッキンを有し、例えば、パッキンは開口２ｆに配置され、ハウジング２ａの内部空間を外部に対して密閉するか又は湿気或いは埃から保護する。
図１（ａ）から明白なように、安全装置２は左右に軸受け部分２ｈとその近傍にキー孔２ｄを有してよく、従ってキー５を左又は右から安全装置２に差し込むことができる。 FIG. 13 is a plan view of the key 5 having the key main claw 5b, the key sub claw 5g, the shaft 5c, the bearing portion 5d, the coupling portion 5e and the grip 5f.
In an advantageous manner, the safety device 2 has a packing, for example the packing is arranged in the opening 2f and seals the internal space of the housing 2a from the outside or protects it from moisture or dust.
As is clear from FIG. 1 (a), the safety device 2 may have a bearing portion 2h on the left and right and a key hole 2d in the vicinity thereof, so that the key 5 can be inserted into the safety device 2 from the left or right.
