この発明はコネクタ、特に複数の印刷配線板用コネクタ
を介して信号の授受を行う制御装置におけるコネクタの
接続状態検出装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of the Invention] The present invention relates to connectors, and particularly to a connector connection state detection device in a control device that transmits and receives signals via a plurality of printed wiring board connectors.
この種の従来装置を第３図に示し、第３図において１は
プログラマブルコントローラ等の制御装置で、２で示す
接点等の動作信号をコネクタ４−１を介して入力１子１

る。この図では分かり易くするために入力用コネクタ４
−１と出力用コネクタ４−ｎの２個しか示していない。This type of conventional device is shown in FIG. 3, in which 1 is a control device such as a programmable controller, and operating signals from contacts, etc. shown at 2 are inputted via a connector 4-1.
1 to imj, and the load 3 is controlled from the output terminals 01 to Om to the connector 4- according to the operating signals. In this diagram, input connector 4 is shown for clarity.
Only two connectors, -1 and output connector 4-n, are shown.
各コネクタ４−１．４−ｎは制御装置１と一体化された
固定側部４１ａ、４ｎａと挿入側部４１ｂ、４ｎｂとに
分離可能で、挿入側部４１ｂ、４ｎｂを固定側部４１１
１１４ｎａに装着することによゆ信号の授受が可能とな
る。Each connector 4-1.4-n can be separated into fixed side parts 41a and 4na integrated with the control device 1 and insertion side parts 41b and 4nb, and the insertion side parts 41b and 4nb are connected to the fixed side part 411.
By attaching it to the 114na, it becomes possible to send and receive signals.

。If the connection state of the connector 4-1 #4-H is poor, normal operation will not be possible, so in this conventional example, one pin of the connector 4-114-n, in this case, the input terminal iml, the input terminal A pin connected to imn is used for detection, and a signal voltage is applied to this detection pin to detect whether a signal is transmitted to input terminals iml and imn, thereby monitoring the connection state of the connector. However, in this conventional example, an input terminal for a control device that monitors the connection state of the connector is required for each connector.
Requires a number of detection input terminals corresponding to the number of connectors.
また、第４図に示すようにコネクタ４が傾斜して装着さ
れた場合或いは完全な接続状態から機械。Also, as shown in FIG. 4, when the connector 4 is installed at an angle, or when the connector 4 is completely connected, the machine cannot be used.
装装置の振動などにより傾斜した状態になった場合制御

ピンの接続が不完全となるが、この場合には検出用ピン

されるという欠点を有する。If the device is tilted due to vibration or the like, even if the detection pin connected to the input terminal in of the control device 1 is connected, the other input terminals i11. The connection of the pin connected to i12 etc. becomes incomplete, but in this case, since the detection pin is connected, there is a drawback that the connection state is detected as normal.

いても第４図に示したようにコネクタが傾斜して取り付
けられた場合には接続不良があるにもかかわらず正常と
して検出してしまうという欠点を有する。Figure 5 shows a different conventional device, with input connector 4-1.
The number of detection input terminals of the control device 1 is reduced by connecting each detection pin of the output connector 4-n with a conductive wire 5. In this case, the number of detection input terminals can be saved, but the conductor 5 that connects the connector 4-I I 4-n must be connected separately from the input and output cables, and the conductor 5 must be connected separately from the input and output cables. This has the disadvantage that the connectors are joined together, making it inconvenient to handle the additional connectors and cables. Furthermore, this conventional device also has the disadvantage that if the connector is installed at an angle as shown in FIG. 4, it will be detected as normal even though there is a connection failure.
この発明の目的は制御装置の入力端子数を節約して確実
にコネクタの接続状態を検出することが可能な装置を提

子の数を節約することができる。The gist of this invention is that in a connector connection state detection device in a control device that sends and receives signals via a plurality of connectors, at least two pins of each connector are connected by a detection connection conductor, and Connect the pins to which the connecting conductors are connected with the inter-connector connecting conductors, connect the detection connecting conductors in series, connect one of the series-connected detection connecting conductors to the detection input terminal of the control device, and complete the series connection. The other point of the detection connecting lead wire is used as the detection signal input terminal. By connecting the detection connecting conductors in series in this manner, only one detection input terminal is required for detecting the connection state of the connector of the control device, and the number of input terminals of the control device can be saved.

Connect the pins at both ends of 14-H to the detection connecting conductor 5-1.5-n
Connect each connector 4-1 $4-E1 with the inter-connector connecting conductor 6-H and connect the detection connecting conductor 5.
-1 #5-n is connected in series. The inter-connector connecting conductor 5-n connects each connector on the fixed part side 41''*4na of the connector 4-1 #4-H, and the connectors are connected to each other by this inter-connector connecting conductor 5-n. One end of the series-connected detection connection conductor 5-1 is connected to the detection input terminal 11 of the control device 1 via the detection pin of the connector 4-1, and the series-connected detection connection conductor 5-1 is connected to the detection input terminal 11 of the control device 1 through the detection pin of the connector 4-1. The other end of n is connected to the output terminal on of the control device 1 via a connector 4-n.

ことを検出することができる。In this connected state, the control device 1 outputs a high-level detection signal to the output terminal ON, then monitors the state of the signal input to the detection input terminal 11, and outputs a high-level detection signal to the detection input terminal 11. When input, it can be detected that the connector is fully connected,
If a high-level detection signal is not input to the detection input terminal i1, it can be detected that the connection state of one of the connectors is incomplete.

It is not necessary, and a detection signal may be artificially applied to the other end of the detection connecting conductor 5-n.
