Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector pin insertion instruction device used for inserting connector inserters (hereinafter referred to as pins) in wiring assembly work.

In general, multi-terminal connectors are widely used for control line exits in various control devices.
This connector consists of a pair of male and female bodies made of synthetic resin, etc., which are regularly arranged with a large number of small holes for inserting pins that serve as connection terminals, and the pins are inserted into the predetermined small holes in the main body. Can be fixed and assembled. That is, a male pin is inserted and fixed into the male main body, and a female pin is inserted and fixed into a small hole in the female main body opposite to the male pin. Since the control wires are crimped and attached to each of the pins in advance, the wiring connection of the connector section is completed by inserting the pins into the corresponding small holes in the main body as described above.

Conventionally, the operation of inserting a pin into a predetermined small hole in the main body was performed as follows. That is,
According to the pin numbers indicated on the wiring diagram, the worker visually checked the pin numbers embossed near the small holes on the main body, selected the corresponding pin number one by one, and inserted the pins into the corresponding small holes. but,
The inner diameter of the small holes is small, about a few millimeters, and many of them are closely packed together, so the pin numbers embossed on each small hole are barely large enough to be seen with the naked eye, and the above-mentioned work is tiring for the eyes. It was a big burden on the workers, such as being unreasonable. Furthermore, since the pin insertion position is indicated on the drawing or list as described above, the pin insertion work must be carried out while looking at the drawings and lists, which often results in erroneous insertion of pins due to misunderstandings or misidentifications.

An object of the present invention is to use a pin guide in which a large number of light emitting elements are arranged so as to face a small hole provided in a connector body, and to stack a connector on this pin guide.
By inputting the desired pin number using a numerical input device, the corresponding light emitting element will emit light, and the small hole overlapping this will be displayed as a pin insertion hole, making it easier to insert the pin into the connector body. To provide a connector pin insertion instruction device which can prevent incorrect pin insertion.

The present invention will be described below with reference to an embodiment shown in the drawings. In Figure 1, 1 is a pin guide, 1a for the male body of the connector and 1a for the female body of the connector.
One set is prepared as b. An insertion position indicator 2 is provided on the upper surface of the pin guide 1, in which a number of light emitting elements are arranged so as to face the small holes formed in the connector body. Also this pin guide 1
As shown in FIG.
, and has a fixing part 13 for overlapping them so that the small holes 12 face the respective light emitting elements of the insertion position indicator 2. As this fixing part 13, a screw type one as shown in FIG. 2 may be used. In addition, in FIG. 2, 14 is the connector body 11.
This is a pin that is inserted and fixed into the small hole 12 of.

Returning to FIG. 1, 4 is a numeric input device for inputting a pin number, using a well-known numeric keypad. 3
is a digital display which displays the pin number entered using the numeric keypad 4. Reference numeral 5 denotes an operation key, which is used to store and reproduce pin numbers.
Numeral 6 is a leading data call key, which is used to call up the leading data of a large number of stored pin numbers.
Note that 10 is a power switch.

FIG. 3 shows the configuration of the control section of the connector pin insertion instruction device shown in FIG. 1. Reference numeral 7 denotes an input/output device which receives numerical data (pin number) inputted using the numeric keypad 4 and outputs this as a display control signal to the insertion position display 2 and digital display 3 via the input/output device 7. For example, numeric keypad 4
When the data "18" is input, an output signal is generated to cause the light emitting element corresponding to pin number 18 of the insertion position indicator 2 to emit light. At the same time, an output signal for displaying the number "18" on the digital display 3 as shown in FIG. 1 is generated.

The operation keys 5 include three keys, namely a read/write switching key 5a and a decrement key 5.
b, and an increment key 5c, and these inputs are applied to the control device 8 via the input/output device 7. The control device 8 writes the numerical data (pin number) input to the input/output device 7 using the numeric keypad 4 into the storage device 9 by instructing the read/write switching key 5a to write. Also, by setting the read/write switching key 5a to read instruction,
Data stored in storage device 9 (pin number)
Read out. Each time the decrement key 5b is operated, the data stored in the storage device 9 is moved back in the order of storage. Each time the increment key 5c is operated, the data stored in the storage device 9 is advanced in the order of storage.

The signal from the start call key 6 is also input to the control device 8 via the input/output device 7, and calls the start of the data stored in the storage device 9, as described above.

Next, the effect will be explained. First, as shown in FIG. 2, stack the connector body 11 on the pin guide 1,
The pin guide 1 is fixed in such a manner that its small holes 12 face the respective light emitting elements of the insertion position indicator 2 provided in the pin guide 1. Next, the operator reads the pin insertion position indicated on the drawing, list, etc., and inputs the numerical data (pin number) using the numeric keypad 4.
For example, when the pin number "18" is input, the data is outputted to the insertion position display 2 and the digital display 3 as a display control output via the input/output device 7 described above. Therefore, the light emitting element corresponding to the pin number "18" on the insertion position indicator 2 emits light, and the number "18" is displayed on the digital display 3. After confirming that the input data is correct using the digital display 3, the operator inserts the second Insert pin 14 as shown in the figure. In this way, according to the predetermined pin numbers indicated in the drawings etc.
The pin 14 can be inserted into the corresponding small hole 12 of the connector body 1, and this work is much easier than the conventional work done by visually checking the pin number directly embossed on the connector body 1. and accurate.

In the above work, each time a pin number is input, a pin is inserted into the corresponding small hole 12. However, when assembling multiple connectors with the same pin arrangement, the above work method requires the same number for each connector body. Data must be entered, which is cumbersome. In such a case, the work will be made easier if you first input and memorize all the numerical data (pin numbers), and when inserting the pin, read out the stored numerical data one by one and display the pin insertion position. Become.

Next, the operating procedure in this case will be explained. First, the read/write switching key 5a is set to write instruction. In this state, numerical data (pin number) is input using the numeric keypad 4 as described above. The input numerical data is written from the input/output device 7 to the storage device 9 via the control device 8. Further, since this numerical data is displayed on the digital display 3 or the like in the same manner as described above, the operator can visually check the displayed numerical data to confirm whether there are any errors. In this way, when numerical data is inputted sequentially using the numeric keypad 4, this data is sequentially written and stored in the storage device 9. In this case, if the input data is erroneous, the decrement key 5b is operated to return the data sequentially stored in the storage device 9 to the erroneous data. Since all of this data is displayed on the digital display 3, erroneous data can be confirmed on the digital display 3 and corrected by inputting correct data in that state.

After storing the correct required amount of numerical data in this way, the read/write switch key 5a is used to instruct read, and the start data call key 6 is operated to call up the start of the data stored in the storage device 9. . After this, each time the increment key 5c is operated, the numerical data stored in the storage device 9 is sequentially read out, causing the corresponding light-emitting element of the insertion position indicator 2 to emit light and displaying the pin number on the digital display 3. Display. Therefore, the operator only has to operate the increment key 5c and sequentially insert the pins 14 shown in FIG. 2 into the positions displayed thereby. In this way, there is no need to enter new data each time a pin is inserted, so the operator can concentrate on the pin insertion work, making the work easier and useful when assembling multiple connectors with the same pin arrangement. It is.

As described above, according to the present invention, it is much easier to insert a pin into a predetermined one of the many small holes provided in the connector body compared to the conventional work that is done while visually checking the numbers embossed on the connector body. can be,
The burden on the operator, such as eye fatigue, can be significantly reduced, and erroneous insertion of pins due to misidentification or misunderstanding can be reliably prevented.
