倒であつた。 Conventionally, in order to crimp a terminal to an insulated wire, first the insulated wire is cut to a certain length using a known insulated wire cutting/stripping machine, and the coating at the end of the insulated wire is stripped off to a certain length. Then, it is necessary to accurately and reliably crimp a terminal of a predetermined shape and size at a predetermined position on the stripped portion using a known terminal crimping machine. That is, in FIG. 1, the terminal 1 (in the embodiment, it is a female terminal)
a, a second gripping portion 1b, and a connecting portion 1c with a male terminal. ) is shown crimped to the end of the covered wire 2 (in the example, the covering is red). Grip accurately and securely leaving a certain length L left over from the end, and the gripping part 1b is the conductor part (stranded wire) 2b of the electric wire 2.
It is necessary to crimp the terminal 1 while firmly grasping the entire circumference. However, when crimping a terminal, although it is rare, the gripping part 1b does not securely grip the conductor part (stranded wire) 2b, and for example, some of the stranded wires of the conductor part 2b are caught in the gripping part 1b.
This may cause the terminal to escape, resulting in terminal crimping failure. Conventionally, the quality of the terminal crimping condition has been determined by human eyes, and this work has been extremely troublesome.

とになる。 First, the terminal crimped electric wire is fixed in a predetermined position as shown in FIG. 2, with the ends of the gripping portions 1a and 1b of the terminal 1 facing upward. First, in order to inspect the quality of the mutual crimping position of the terminal 1 and the electric wire 2 and the quality of the gripping state of the grip portion 1a, the projecting system A illuminates the terminal crimped portion of the terminal crimped electric wire downward. At this time, the red laser beam from the cylinder 4 is polarized by the polarizing plate 6 and irradiates the terminal crimping location. Then, the reflected light passes along the optical axis C2 , passes through the polarizing plate 8 and the lens 9, and reaches the light receiving surface 7a. At this time, among the reflected light, the light from the terminal 1 and the conductor portion 2b is reflected almost in the polarized state by the polarizing plate 6, but the covering portion 2
The light from a (red) becomes diffusely reflected light. Therefore, when the reflected light passes through the polarizing plate 8, since the difference in polarization direction between the polarizing plates 6 and 8 is approximately 90 degrees, the reflected light from the terminal 1 and the conductor portion 2b hardly passes through. The reflected light (diffusely reflected light) from the covering portion 2a reaches the light receiving surface 7a in a polarized state.

ことになる。 The light is converted into an electrical signal by the light receiving element on the light receiving surface 7a, and further converted into a continuous waveform signal by scanning in the axial direction of the terminal crimped wire by means 7b. Furthermore, this signal is compared with two types of information recorded in advance in the memory 10 {see each row in FIGS. 3 and 4}, and the signal of the portion corresponding to the length of the covering end L is l 1 Determine whether it is smaller than l2 and larger than l2 . If the signal of the portion corresponding to the length of the covered end L is larger than l 1 or smaller than l 2 , then
There is a possibility that the gripping part 1b is gripping a part of the covering part 2a, or the gripping part 1a is gripping a part of the conductor part 2b, and the means 12 issues a warning as the terminal crimping position is incorrect. It turns out.

は、約1.5〜2Vあることがわかる。 After the above-mentioned inspection is completed, the terminal crimping condition is then inspected to determine whether the conductor portion 2b is securely gripped by the grip portion 1b or whether some of the conductive wires 2c have escaped. Before explaining the operation of this test, the wire 2 of the terminal crimped wire, which is the object to be tested, has a conductor portion 2b of approximately 1.3 mm in diameter.
A red covered electric wire with an outer diameter of the covered part 2a of about 2 mm,
The ring-shaped electrode 13 has a wire diameter of approximately 1 mm.
FIG. 7 shows the arc discharge characteristics between the electrode 13 and the terminal crimping location based on the results of an experiment with the inner diameter divided into three stages: 8 mm, 9 mm, and 10 mm.
In other words, the solid line in FIG. 7 is the result of discharging with the electrode 13 set to negative and the terminal crimped location set to positive, but the E1 wire ensures that the grip part 1b is connected to the conductor part 2b.
Check the normal terminal crimping condition, and also the E 2 wire,
A terminal crimping failure condition in which the grip portion 1b did not securely grip the conductor portion 2b and some of the conductor wires 2c escaped, is as follows.
are shown respectively. In addition, the broken line in Fig. 7 indicates the electrode 1.
The E 1 ' line indicates a normal terminal crimped condition, and the E 2 ' line indicates a terminal crimped defective condition. As is clear from FIG. 7, the potential difference between both ends of the resistor 14f at the start of discharge depending on whether the terminal crimping condition is good or bad, i.e.
It can be seen that the difference between the E 1 line and the E 2 line, or the difference between the E 1 ' line and the E 2 ' line, is about 1.5 to 2 V.
そこで今第２図のように、回路１４により電極

およびE2線が以下の説明で重要となる。 Now, as shown in Figure 2, the electrode 13 is connected to the negative side by the circuit 14, and the terminal crimping point is connected to the positive side, so the solid lines in Figure 7, the E1 wire and the E2 wire, are important in the following explanation. becomes.

良として手段１６により警告が発せられる。 Now let us assume that the inner diameter of the ring-shaped electrode 13 is 9 mm.
Furthermore, the voltage value input to the discrimination circuit 15 is set to about 7.5V in advance. Then, the secondary voltage of the transformer 14c is increased by the autotransformer 14b, causing an arc discharge between the electrode 13 and the terminal crimping location. At this time, if some of the conductive wires 2c escape from the grip part 1b as shown in FIG. 6, the distance between the electrode 13 and the conductive wire 2c is short,
Discharge will start when the potential difference between both ends of f is about 6 to 6.5V. Then, in the circuit 15, the potential difference (6 to 6.5V) between both ends of the resistor 14f
Since it is determined that the voltage is lower than the previously input voltage (approximately 7.5V), the circuit 15 outputs a signal, and as a result, a warning is issued by the means 16 that the terminal crimping by the grip portion 1b is defective. .

技術範囲に含まれることはもちろんである。 The above description is an example, and the circuit 14 may be an AC circuit. Further, the electrode 13 is not limited to a ring shape, but may be a needle shape with the tip thereof positioned near the gripping portion 1b, or the lower half of the ring electrode 13 in FIGS. It may be in the shape of a cut semicircle, or it may be a ring-shaped flat plate, a semicircular flat plate, or various other shapes. It goes without saying that the technical scope of the present invention also includes the replacement of each component with equivalents.

ことができる。 As described above, in this invention, the electrode 13 is placed close to the terminal crimping portion of the terminal crimped electric wire, and the electrode 13
Since a high voltage is applied between the terminal and the terminal crimping point to cause an arc discharge, by comparing whether the starting voltage of the discharge is smaller than a preset value, the terminal crimping state, that is, the grip portion 1b can be determined. It is possible to easily determine whether the grip state of the conductor portion 2b is good or bad.
