CONSTITUTION:A confirmation apparatus 1 is inserted, by means of connectors, across connection signal lines between a servoamplifier connected via a connector and its host control apparatus. That is to say, a male-side connector inside a connector case 11 for a lead wire 2 to the apparatus 1 is inserted into a female-side connector at the servoamplifier outside the figure; a male-side connector at the host control apparatus outside the figure is connected to a female connector 3F at the apparatus 1; the host control apparatus is coupled to the servoamplifier. Check pins 7 which check, by means of a measuring instrument or the like, the state of individual signal lines at the connector part and LED'd 9 for H/L level discrimination of the signal lines are arranged in good order on a printed-circuit board 4 inside the confirmation apparatus 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a confirmation device for investigating the state of a signal line connected to a servo amplifier, which is a control device for a servo motor, by a connector. In the following figures, the same reference numerals indicate the same or corresponding parts.

2. Description of the Related Art FIG. 4 is an explanatory view of a conventional method for confirming the state of this kind of signal line. In the same figure (A), 2 is a lead wire with a connector consisting of a signal line 10 for connecting a host controller (sequencer, etc.) (not shown) to a servo motor, and 11 is a female connector (not shown) of a counterpart servo amplifier. It is a case of the male side connector that is inserted into. Further, FIG. 3B shows the soldered portion of the signal line 10 to the terminal of the male side connector 3M inside, with the connector case 11 removed.

Conventionally, as a method of measuring the signal of this kind of signal line 10, as shown in FIG. 4, the connector case 11 is first removed and the soldering terminal portion 12 is measured with a clip. The lead wire 13 is gripped, and the signal is measured through the lead wire 13 by a measuring instrument such as a synchroscope or a tester (not shown). The servo amplifier often uses a connector having three rows of terminals because of the large number of signal lines 10. To measure the terminal portion of the second row, grasping with a clip is not possible and one row is used. The second line was measured after removing the soldering of the signal line of the eye.

[0004]

However, in the signal line state confirmation method as described above, when it is desired to investigate a defective portion, it is necessary to predict the defective portion in advance and attach the lead wire 13 to the terminal of the signal line. There is. If the prediction is further wrong, the work of reattaching the lead wire 13 is repeated.

Further, if many lead wires 13 are attached at one time, it is easy to malfunction due to the influence of noise, and the measurement location is also likely to be wrong. Further, repeated soldering may cause a secondary failure, which is not suitable as work when traveling to a customer. Therefore, it is an object of the present invention to provide a connector connection signal line state confirmation device that can easily carry out a signal investigation in a connector without requiring such work.

[0006]
