- 3rd invention of this application is an apparatus which evaluates the crimping
- a lower limit value and an upper limit value of terminal elongation are set instead of the lower limit and upper limit of the crimp height. Since the quality of the crimping part is judged by whether or not the elongation of the terminal measured after crimping is within the allowable range between the lower limit value and the upper limit value, the crimping part can be easily evaluated. . That is, since it is easier to measure the length of the terminal than to measure the crimp height, the automation can be easily realized, thereby enabling a total inspection. As a result, all the performances of the crimped product can be guaranteed.
- the second invention it is possible to easily evaluate the quality of the crimping part by setting the terminal on the measuring table and detecting where the tip of the terminal is located.
- the quality of the crimping portion can be easily evaluated by detecting the elongation of the terminal by the detecting means and determining the extent of the elongation by the determining means.

- FIG. 4A is a side view showing a state before crimping the terminal and an electric wire
- FIG. 4B is a side view showing a state after crimping.
- FIG. 5 is a cross-sectional view showing a state where a terminal and an electric wire are crimped by a crimper and an anvil.
- FIG. 6 is a cross-sectional view of the crimping portion between the terminal and the electric wire.
- FIG. 1 is an explanatory view of an evaluation method of an embodiment
- FIG. 1 (a) is a side view showing a state before crimping a terminal and an electric wire
- FIG. 1 (b) is a side view showing a state after crimping
- FIG. 1C is a characteristic diagram showing the relationship between crimp height and terminal elongation due to crimping.
- the structure of the terminal 10 and the structure of the electric wire W are the same as that of what was shown in FIG. 4, those description is abbreviate
- the total length L0 of the terminal 10 before crimping is grasped in advance, and the total length L1 of the terminal 10 after crimping is detected by means such as a sensor or a switch.
- the elongation of the terminal 10 after crimping relative to the length of the terminal 10 before crimping is detected by subtracting the total length L0 of the terminal 10 before crimping from the total length L1 of the terminal 10 after crimping.
- the evaluation method of the present embodiment utilizes the fact that there is a correlation between the crimp height C / H due to crimping and the elongation of the terminal 10, and instead of the lower limit value and the upper limit value of the crimp height C / H.
- the lower limit value and upper limit value of the terminal elongation are set, and whether or not the quality of the crimping part is good is determined by whether or not the elongation of the terminal 10 measured after crimping is within the allowable range between the lower limit value and the upper limit value. Therefore, the crimping part can be easily evaluated. That is, since it is easier to measure the length of the terminal 10 than to measure the crimp height C / H, automation can be easily realized, thereby enabling 100% inspection. As a result, all the performances of the crimped product can be guaranteed.
- FIG. 2 As a specific evaluation apparatus for carrying out this method, for example, the one shown in FIG. 2 can be considered.
- the detection means 20 described above is provided in a form attached to a measurement table (not shown).
- the measurement table is a table on which the terminal 10 can be set with reference to one end in the length direction (that is, the rear end connected to the electric wire).
- the position of the other end (that is, the tip) in the length direction of the terminal 10 set on the measurement table is defined based on the lower limit value and the upper limit value of elongation set in advance for the terminal after crimping. It is detected whether it is within the permissible region (ie, permissible range) S.
- the detection means 20 turns on a display device such as a lamp with a determination of “OK”.
- the detection means 20 determines “No (NG)”.
- the display device such as a lamp is not turned on. Therefore, the quality of the crimping part can be evaluated based on whether or not the lamp is lit.
- these determination contents are set in advance so as to coincide with the determination contents by the crimp height C / H. That is, since the crimp height C / H of the conductor crimping portion by the wire barrel 11A shown in the first stage and the wire barrel 11D shown in the fourth stage exceeds the upper limit value or the lower limit value, the determination is “No (NG)”. Since the crimp height C / H of the conductor crimping portion by the wire barrels 11B and 11C shown in the second and third stages is within the upper limit value and the lower limit value, the determination is “good (OK)”. is there.
- FIG. 3 shows an example of an evaluation apparatus according to another embodiment.
- an optical detection mechanism in which the light emitting unit 31 and the light receiving unit 32 are paired is used as a detection means.
- the light emitted from the light emitting unit 31 enters the light receiving unit 32, and the tip of the terminal 10 set on the measurement table enters the middle of the light path. Therefore, the received light amount is reduced by the area where the tip of the terminal 10 blocks the light entering the light receiving unit 32 from the light emitting unit 31.
- the range of the amount of received light corresponding to the upper limit value and the lower limit value of the extension of the terminal 10 can be set. By measuring, the elongation of the terminal 10 can be detected, and based on this, the quality of the crimping part can be evaluated by a determination means (not shown).
- the quality of the crimping part can be easily evaluated by detecting the elongation of the terminal 10 by the detecting means, that is, the light emitting part 31 and the light receiving part 32, and determining the extent of the elongation by the judging means. it can. That is, as shown in FIG. 3, since the terminal 10A shown in the first stage does not block the light emitted from the issuing unit 31, it does not reach the received light amount corresponding to the lower limit value of the terminal elongation, The determination means determines “No (NG)”.
- the received light amount is within the range of the received light amount corresponding to the upper limit value and the lower limit value of the extension of the terminal, so the determination means is “good (OK)”. Is determined. And since terminal 10D shown in the 4th stage has interrupted all the light discharge
