Description

[Detailed description of the invention] (a) Technical field of the invention The present invention relates to a wiring testing device for electrical equipment, etc., and in particular to a cable wiring verification/inspection device suitable for use in wiring verification and wiring inspection of cables with connectors. .

(b) Prior art and problems Figure 1 shows an explanatory diagram of a conventional cable number verification method when connecting a connector. In the figure, when connecting the first and second connectors 2 _A and 2 _B to both terminals of the cable 1 with one end on the A side and the other end on the B side, respectively, in correspondence with the terminal numbers of each connector, the buzzer 3 and a probe rod 4 are used to check continuity for each strand of the cable. This work order starts with
Wire all the bare wires on the A side of the cable 1 to the connector 2 _A of the first connector 2 A, and then test the continuity of the buzzer 3 by probing the probe rod 4 between the terminal of the first connector 2 _A and the bare wire on the B side of the cable 1. , check the corresponding wire number, and wire it to the terminal of the second connector _2B . This repeating operation is generally performed for all the wires on _{the B} side of the cable 1. However, this work is easy for flat cables where the terminal positions on both the A side and B side are clear, but it is necessary to process the terminals of multicore cables with uneven arrangement of strands and after completion. The inspection has the drawback of requiring a large amount of time.

(c) Purpose of the invention In view of the above-mentioned drawbacks of the conventional technology, the present invention provides a system in which the corresponding wire number is immediately displayed by detecting any wire with a probe rod, and terminal connection inspection after completion is also easy. The purpose of this invention is to provide a cable wiring verification inspection device that can be checked in a short time.

(d) Structure of the invention According to the invention, the purpose is to provide a device for collating and inspecting cable wiring, which is used when connecting connectors to both ends of a cable having a plurality of strands. a first terminal group connectable to a terminal group of a first connector connected to each strand at one end of the cable; and a second terminal group to be connected to each strand at the other end of the cable. a second terminal group connectable to the terminal group; a meter reading means with one end grounded for each strand at the other end of the cable; and the first connector individually connected between the first terminal group and a power source. This is achieved by providing a cable wiring verification/inspection device characterized in that it is provided with a display means for displaying the terminal number of the second terminal group, and a switch means for individually grounding the terminals of the second terminal group.

(e) Examples of the invention Examples of the invention will be described below in detail with reference to drawings.
In the figure, parts corresponding to those in FIG. 1 are designated by the same reference numerals, and redundant explanation thereof will be omitted.

FIG. 2 shows a circuit diagram of the cable wiring verification/inspection device of the present invention.

In the figure, reference numeral 5 denotes a cable wiring verification/inspection device, which is equipped with a meter-detecting rod 4 as a meter-detecting means, which is connected to a lead wire with one end grounded, and is connected to each element wire at one end of the cable 1 for wiring verification/inspection. The first
A first terminal group _{2A '} (for example, a mating connector that has a male-female relationship with connector _2A ) that can be freely connected to the terminal group of connector 2A, and a first terminal group 2A' that can be connected to the terminal group of connector 2A, and a A second terminal group _2B ' that can be freely connected to the terminal group _2B of the second terminal group _2B to be used is provided, and a For example, a series circuit of a light emitting diode 6 and a resistor 7 is provided as a means for displaying the terminal number of the connector _2A of the connector 1, and the other end of the power source 8 is grounded. In addition, as a means for individually grounding the terminals of the second terminal group _2B ', each terminal is branched, and some of them are grounded through a series circuit of a switch 9 and a diode 10, and the other part is connected to a movable contact. are connected to each fixed contact of the grounded rotary switch 11.

The same numbers as the terminal numbers of the connected connectors _2B are indicated at corresponding positions on each mounting board (not shown) of the fixed contacts of the switch 9 and the rotary switch 11.

Next, the effect will be explained.

The first terminal group 2A' is connected to the first connector _2A to which all the wires on one end of the cable 1 on the _A side are connected, and the terminals of each wire on the other end of the cable 1 on the B side are stripped of their coatings. to prepare for connection to the second connector _2B . Further, the second connector 2 _B also has the second terminal group 2 _B ′
Connect to. Next, by touching any terminal of each wire on the B side of the cable 1 with the probe rod 4 whose one end is grounded, the first connector 2 _A on the A side of the cable 1 connected to the arbitrary terminal will be connected to the first connector 2 The series circuit of the light-emitting diode 6 and the resistor 7, each of which has a display number corresponding to the terminal number of the first connector _2A , becomes a closed circuit with respect to the power supply 8 via the terminal group 2A _' , so that the corresponding light emission occurs. The diode 6 lights up, and the terminal number of any strand that comes into contact can be immediately visually confirmed.

Therefore, disconnect the probe rod 4 and connect the wire whose terminal number is known to the corresponding terminal of the connector _2B .
After this, the movable contact of the rotary switch 11 is set to the "OFF" position (floating fixed contact position), and each switch 9 is set to "ON" only the switch corresponding to the terminal number of the connected connector _2B . If there is no error in the connection to the terminal, the light emitting diode 6 of the corresponding terminal number will light up, but if it is incomplete, it will not light up, or if the incomplete state is in contact with the adjacent terminal, the light emitting diode 6 corresponding to the adjacent terminal will light up. It also lights up, allowing you to discover connection errors.

When all the switches 9 are turned "ON" and all the light emitting diodes 6 are lit by repeating the above operations, the connection work is completed. Here, the diode 10 serves to prevent current from flowing around, and the resistor 7 serves to protect the light emitting diode 6.

Next, the wiring inspection of cable 1 will be described. All the switches 9 are turned "OFF" to turn off all the light emitting diodes 6. The inspection can be determined by rotating the rotary switch 11 from "OFF" in the order of the terminal numbers and confirming that the light emitting diode having the display number corresponding to the contact number of the rotary switch 11 lights up. At this time, if a plurality of light emitting diodes are lit at the same time or not lit at the same time, it can be considered as an abnormality.
Also, the rotary switch 11 is not provided and the switch 9 is
Although it is possible to test by repeatedly turning "ON" and "OFF" one by one, it is faster to check using the rotary switch 11. Note that the light emitting diode may be a light bulb.

(f) Effects of the invention As explained in detail above, according to the cable wiring verification/inspection device of the invention, the terminal number can be immediately confirmed by simply touching any strand, and the inspection results can be obtained in a short time. This is effective in preventing incorrect wiring and improving work efficiency.
