일반적으로 커넥터에 연결된 케이블의 불량 즉, 단선 또는 합선, 접촉불량은 케이블을 사용하는 기기에 에러를 유발시키는 요인이 된다. 따라서, 케이블의 불량상태를 체크하기 위해서는 케이블의 한쪽 또는 양쪽에 멀티테스트로 모든핀에 일일이 도통상태를 체크해야 하므로 불편할 뿐만아니라 상당한 시간이 소요되는 문제점이 있었다.In general, a defective cable connected to a connector, i.e., disconnection, short circuit, or poor contact, causes errors in equipment using the cable. Therefore, in order to check a bad state of the cable, it is inconvenient to take a considerable time because it is necessary to check the conduction state of all pins by multi-test on one or both sides of the cable.
상술한 문제점을 극복하기 위하여, 본 고안의 목적은 케이블의 불량 상태 즉 단선, 합선 또는 접촉불량등을 발광소자를 이용하여 표시할 수 있는 장치를 제공하는데 있다.In order to overcome the above problems, an object of the present invention is to provide a device capable of displaying a defective state of the cable, that is, disconnection, short circuit or contact failure using a light emitting element.

By connecting the third or fourth connector to the other side of the cable connector in the state that the connector of the cable is plugged in, disconnection or short-circuit state can be inspected depending on whether the display means is displayed.
이하, 첨부된 도면을 참조하여 본 고안에 의한 케이블 상태 검사장치의 바람직한 실시예를 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the cable state inspection apparatus according to the present invention.
제1도는 본 고안에 의한 케이블 상태 검사장치의 회로도이다.1 is a circuit diagram of a cable state inspection apparatus according to the present invention.
제1커넥터(J1)의 짝수핀(2,4,6,…,2n)은 전원공급단(Vcc)에 접속되고, 홀수핀(1,3,5,…,2n-1)은 케이블에 접속된다. 저항들(R1~Rn)의 일단은 병렬로 홀수핀(1,3,5,…2n-1)에 접속되고, 타단은 각각 발광다이오드(이하 LED라 함)(D1~Dn)에 직렬로 접속된다. 상기 LED들(D1~Dn)의 캐소드단은 접지되어 있다. 제2커넥터(J2)의 홀수핀(1,3,5,…,2n-1) 및 짝수핀(2,4,6,…,2n)은 케이블에 접속된다. 제3커넥터(J3)의 홀수핀 및 짝수핀이 일대일로 접속되어있다. 제4커넥터(J4)의 홀수핀과 짝수핀을 인근선끼리 접속되어 있다.Even pins (2, 4, 6, ..., 2n) of the first connector (J1) are connected to the power supply terminal (Vcc), and odd pins (1, 3, 5, ..., 2n-1) are connected to the cable. do. One end of the resistors R1 to Rn is connected in parallel to the odd pins 1, 3, 5, ... 2n-1, and the other end is in series with the light emitting diodes (hereinafter referred to as LEDs) D 1 to Dn, respectively. Connected. The cathode ends of the LEDs D 1 to Dn are grounded. The odd pins 1, 3, 5, ..., 2n-1 and the even pins 2, 4, 6, ..., 2n of the second connector J2 are connected to the cable. The odd pins and even pins of the third connector J3 are connected one-to-one. The odd pins and even pins of the fourth connector J4 are connected to each other.
이어서, 제1도의 동작을 설명하기로 한다.Next, the operation of FIG. 1 will be described.
제1도에 의하면, 제1 또는 제2커넥터(J1,J2)에 케이블의 커넥터 한편에 접속했을 때 케이블의 홀수핀과 짝수핀 사이에 합선이 없으면 LED(D1~Dn)는 점등되지 않는다. 이때 제1 또는 제2커넥터(J1,2)는 SCIC(Small Computed Interface Circuit)의 규격에 준한다. 단, 케이블 커넥터의 홀수핀과 홀수핀, 짝수핀과 짝수핀 사이의 합선불량은 커넥터의 구성상 발생되지 않는다.According to FIG. 1, when the first or second connectors J1 and J2 are connected to one side of the cable connector, the LEDs D 1 to Dn do not light up when there is no short circuit between the odd pins and the even pins of the cable. In this case, the first or second connectors J1 and 2 comply with the specifications of Small Computed Interface Circuit (SCIC). However, short circuit between odd pin and odd pin, even pin and even pin of cable connector does not occur due to the configuration of connector.
한편, 제1 또는 제2커넥터(J1,J2)와 케이블의 커넥터에 접속된 상태에서 반대편 케이블 커넥터에 제3커넥터(J3)를 접속한다. 이때 공급전원(Vcc)는 제1또는 제2커넥터(J1,J2)의 홀수핀을 통해 제3커넥터(J3)의 홀수핀으로 공급된다. 다시 제3커넥터(J3)의 짝수핀을 통해 상기 제1또는 제2커넥터(J1,J2)의 짝수핀으로 그리고 저항들(R1~Rn)을 통해 다이오드들(D1~Dn)을 거쳐 접지되는 폐회로가 형성된다. 여기서, 케이블 내에서 또는 커넥터와 케이블간에 단선일 경우 해당핀의 LED는 점등되지 않으므로, 단선이 없으면 LED(D1~Dn)는 모두 발광하게 된다.On the other hand, the third connector J3 is connected to the opposite cable connector while being connected to the first or second connector J1, J2 and the cable connector. At this time, the power supply Vcc is supplied to the odd pins of the third connector J3 through the odd pins of the first or second connectors J1 and J2. The closed circuit is grounded to the even pins of the first or second connectors J1 and J2 through the even pins of the third connector J3 and through the diodes D1 to Dn through the resistors R1 to Rn. Is formed. Here, if there is a disconnection in the cable or between the connector and the cable, the LED of the corresponding pin is not lit, so if there is no disconnection, all of the LEDs D 1 to Dn emit light.
또한, 제1또는 제2커넥터(J1,J2)와 케이블의 커넥터에 접속된 상태에서 반대편 케이블 커넥터에 제4커넥터(J4)를 접속할 때 공급전원(Vcc)은 제1또는 제2커넥터(J1,J2)의 홀수핀을 통해 케이블 커넥터로 공급된다. 다시 제4커넥터(J4)의 홀수핀을 통해 제4커넥터(J4)의 짝수핀으로 공급된다. 제4커넥터(J4)의 짝수핀에서 저항들(R1~Rn)을 통해 LED(D1~Dn)로 구동되는 폐회로가 형성된다. 여기서, 케이블의 인접선이 단선일 경우 해당핀의 LED는 점등되지 않으므로 합선 또는 단선의 불량을 체크할 수 있다.In addition, when the fourth connector J4 is connected to the opposite cable connector while the first or second connectors J1 and J2 are connected to the connector of the cable, the power supply Vcc is connected to the first or second connector J1, It is supplied to the cable connector through the odd pin of J2). Again, the even pins of the fourth connector J4 are supplied to the even pins of the fourth connector J4. A closed circuit driven by the LEDs D 1 to Dn is formed through the resistors R1 to Rn at the even pins of the fourth connector J4. Here, if the adjacent line of the cable is disconnected, the LED of the corresponding pin is not lit, so that a short circuit or a disconnection may be checked.
이상으로 설명한 바와 같이 본 고안에 의한 케이블 상태 검사장치는 LED를 검사용 커넥터에 채용하여 케이블 전체를 LED상태에 따라 손쉽게 빠른 시간내에 케이블의 불량을 확인할 수 있는 이점이 있다.As described above, the cable state inspection apparatus according to the present invention has an advantage that a cable can be easily checked within a short time according to the state of the LED by adopting the LED to the connector for inspection.
