The side CPU received a signal to check for cable disconnection, incorrect connection, and short circuit (for example, see Patent Document 1).

特開２０００−２４１４８０（図１）JP 2000-241480 (FIG. 1)

従来のケーブルチェッカは各単線毎に順次点検するので回路が複雑であった。   Since the conventional cable checker sequentially inspects each single wire, the circuit is complicated.

本発明によれば、ケーブルの断線、誤結線、短絡を調べるケーブルチェッカにおいて、ケーブルの各単線に対応する複数の端子を有してケーブルの一端が接続される第１コネクタとケーブルの他端が接続される第２コネクタを備え、第１コネクタと第２コネクタの対応する各端子間に第１の発光ダイオードを夫々接続するとともに、第１の発光ダイオードを電源に直列に接続し、第１の発光ダイオード間に第２の発光ダイオードを直列に接続したことを特徴とする。   According to the present invention, in the cable checker for checking the disconnection, misconnection, and short circuit of the cable, the first connector having a plurality of terminals corresponding to each single wire of the cable and to which one end of the cable is connected and the other end of the cable are A second connector to be connected, the first light emitting diode is connected between the corresponding terminals of the first connector and the second connector, respectively, and the first light emitting diode is connected in series to the power source, A second light emitting diode is connected in series between the light emitting diodes.

本発明によれば、簡単な構成で安価にできるという効果がある。   According to the present invention, there is an effect that it can be made inexpensive with a simple configuration.

ケーブルチェッカはケーブルの各単線に対応する複数の端子を有してケーブルの一端が接続される第１コネクタとケーブルの他端が接続される第２コネクタを備え、第１コネクタと第２コネクタの対応する各端子間に第１の発光ダイオードを夫々接続するとともに、第１の発光ダイオードを電源に直列に接続し、第１の発光ダイオード間に第２の発光ダイオードを直列に接続する。   The cable checker has a plurality of terminals corresponding to each single wire of the cable, and includes a first connector to which one end of the cable is connected and a second connector to which the other end of the cable is connected. A first light emitting diode is connected between the corresponding terminals, the first light emitting diode is connected in series with the power supply, and a second light emitting diode is connected in series between the first light emitting diodes.

本発明に係るケーブルチェッカの実施例１を図１の添付図面に基づいて説明する。   A cable checker according to a first embodiment of the present invention will be described with reference to the attached drawing of FIG.

ケーブルチェッカ１は、チェックしようとするケーブル２の一端が接続される第１コネクタＣＮ１と、ケーブル２の他端が接続される第２コネクタＣＮ２を備え、第１コネクタＣＮ１及び第２コネクタＣＮ２はケーブル２の各単線２１〜２４に対応して４つの端子ＣＮ１−１〜ＣＮ１−４，ＣＮ２−１〜ＣＮ２−４を有している。   The cable checker 1 includes a first connector CN1 to which one end of a cable 2 to be checked is connected and a second connector CN2 to which the other end of the cable 2 is connected. The first connector CN1 and the second connector CN2 are cables. The four terminals CN1-1 to CN1-4 and CN2-1 to CN2-4 are provided corresponding to the two single wires 21 to 24, respectively.

そして、第１コネクタＣＮ１と第２コネクタＣＮ２の対応する端子間には第１の発光ダイオードＬＥＤ１１〜ＬＥＤ１４が夫々接続され、第１の発光ダイオードＬＥＤ１１〜ＬＥＤ１４は電源スイッチ３と定電流回路４を介して直流電源５に直列に接続され、更に、第１の発光ダイオードＬＥＤ１１〜ＬＥＤ１４間に第２の発光ダイオードＬＥＤ２１〜ＬＥＤ２４が直列に接続されて構成している。   The first light emitting diodes LED11 to LED14 are respectively connected between corresponding terminals of the first connector CN1 and the second connector CN2, and the first light emitting diodes LED11 to LED14 are connected via the power switch 3 and the constant current circuit 4. The second light emitting diodes LED21 to LED24 are connected in series between the first light emitting diodes LED11 to LED14.

こうして構成されたケーブルチェッカ１は、電源スイッチ３をオンすると、全ての第１の発光ダイオードＬＥＤ１１〜ＬＥＤ１４と第２の発光ダイオードＬＥＤ２１〜ＬＥＤ２４が点灯し、電源スイッチ３をオフすると、全ての第１の発光ダイオードＬＥＤ１１〜１４と第２の発光ダイオードＬＥＤ２１〜２４が消灯する。そして、ケーブル２をチェックするには、まず、第１コネクタＣＮ１にケーブル２の一端側のコネクタＣＮ３を接続し、第２コネクタＣＮ２にケーブル２の他端側のコネクタＣＮ４を接続し、それから電源スイッチ３をオンする。ケーブル２に断線や誤結線や短絡の異常がなければ、第１の発光ダイオードＬＥＤ１１〜ＬＥＤ１４はアノード−カソード間の電位差がなくなるので消灯し、第２の発光ダイオードＬＥＤ２１〜ＬＥＤ２４が点灯する。   In the cable checker 1 thus configured, all the first light emitting diodes LED11 to LED14 and the second light emitting diodes LED21 to LED24 are turned on when the power switch 3 is turned on, and all the first light emitting diodes LED21 to LED24 are turned off when the power switch 3 is turned off. The light emitting diodes LED11-14 and the second light emitting diodes LED21-24 are turned off. In order to check the cable 2, first, the connector CN3 on one end side of the cable 2 is connected to the first connector CN1, the connector CN4 on the other end side of the cable 2 is connected to the second connector CN2, and then the power switch Turn 3 on. If there is no disconnection, incorrect connection, or short circuit in the cable 2, the first light emitting diodes LED11 to LED14 are turned off because there is no potential difference between the anode and the cathode, and the second light emitting diodes LED21 to LED24 are turned on.

また、ケーブル２が断線や誤結線や短絡で異常がある場合、例えば、ケーブル２の単線２１に異常がある場合、異常がある単線２１には電流が流れないのでその端子ＣＮ１−１とＣＮ２−１間に接続された第１の発光ダイオードＬＥＤ１１が点灯し、また、第２の発光ダイオードＬＥＤ２１〜ＬＥＤ２４も点灯し、その他の第１の発光ダイオードＬＥＤ１２，ＬＥＤ１３，ＬＥＤ１４はアノード−カソード間の電位差がなくなるので消灯する。   Further, when the cable 2 is abnormal due to disconnection, misconnection or short circuit, for example, when there is an abnormality in the single wire 21 of the cable 2, no current flows through the single wire 21 with abnormality, so its terminals CN1-1 and CN2- The first light emitting diode LED11 connected between 1 is turned on, the second light emitting diodes LED21 to LED24 are also turned on, and the other first light emitting diodes LED12, LED13, and LED14 have an anode-cathode potential difference. It goes out because it disappears.

このように、ケーブルチェッカ１はケーブル２に異常がある場合に、異常がある単線間に接続された第１の発光ダイオードが点灯することで異常を知ることができる。   Thus, when the cable checker 1 has an abnormality in the cable 2, the abnormality can be known by turning on the first light emitting diode connected between the single wires having the abnormality.
