Problems solved by technology

[0003] 1) The test of the pressure and the analysis of the section of the terminal are destructive tests. The samples after the test cannot be used normally and can only be scrapped, resulting in waste of materials;
[0004] 2) The detection efficiency is too low, which seriously affects the production efficiency, and can only be used as a random inspection item, and cannot achieve full inspection coverage;
[0005] 3) The wire body is a material with a fast production cycle and mass production, which requires high process balance. The above test cycle is long, and it is not suitable for inclusion in the QC (Quality Control, quality control) process of mass production.

Embodiment 1

[0091] Embodiment one (as figure 1 shown)

[0092] The measurement slot includes a first sub-slot and a second sub-slot which are independent of each other, the first section 102 forms the first sub-slot, and the second section 104 forms the second sub-slot.

[0093] The measurement slot includes a first sub-slot and a second sub-slot independent of each other, the first section 102 forms the first sub-slot, and the second section 104 forms the second sub-slot, that is, two slots are opened on the test bench 10, so that the first section One section 102 and the second section 104 are set separately, and are respectively used to detect the relationship between the crimping height of the core wire crimping part and the upper limit value and the lower limit value, so that the crimping height of the core wire crimping part and the There is no sequence for judging the upper limit value and the lower limit value, and the detection process is more flexible and free. You can use the fi...

Embodiment 2

[0097] Embodiment two (as figure 2 shown)

[0098] The difference from Embodiment 1 is that the depth L2 of the first section 102 is smaller than the crimping width, and the depth L1 of the second section 104 is greater than or equal to the crimping width. The evaluation principle is as follows:

[0099] It is relatively simple to first use the second section 104 to evaluate the relationship between the crimping height and the lower limit value.

[0100] If the crimping part of the core wire can all enter the second section 104, then the judgment result is unqualified; if the crimping part of the core wire cannot completely enter the second section 104, it shows that the crimping height does not exceed the lower limit, and then use the first section A period of 102 is used to evaluate the relationship between the crimp height and the upper limit value. If the crimping part of the core wire cannot reach the bottom of the first section 102, the judgment result is unqualified....

Embodiment 3

[0101] Embodiment three (as image 3 shown)

[0102] The difference from Embodiment 1 is that the depth L2 of the first section 102 is greater than or equal to the crimping width, and the depth L1 of the second section 104 is smaller than the crimping width. The evaluation principle is as follows:

[0103] It is relatively simple to first use the first section 102 to evaluate the relationship between the crimping height and the upper limit.

[0104] If the crimping part of the core wire cannot completely enter the first section 102, then the judgment result is unqualified; if the crimping part of the core wire can completely enter the first section 102, it shows that the crimping height does not exceed the upper limit, and then use the first section 102. The second stage 104 is to evaluate the relationship between the crimp height and the lower limit. If the crimping part of the core wire cannot reach the bottom of the second section 104, then the judgment result is qualifie...

Abstract

The invention provides a terminal crimping quality assessment apparatus, a terminal crimping quality assessment method and a terminal crimping system. The terminal crimping quality assessment apparatus includes a testboard, wherein a measurement groove is formed in the testboard; the width direction of the measurement groove is corresponding to the height direction of a core wire crimping portionof a terminal; the measurement groove includes a first segment and a second segment; the width of the inlet of the first segment is equal to the upper limit of the qualified crimping height of the core wire crimping portion; the width of the other portions is greater than or equal to the upper limit, and the depth of the first segment is greater than or equal to half of the crimping width of the core wire crimping portion; and the width of the inlet of the second segment is equal to the lower limit of the qualified crimping height, and the width of each of the other portions is greater than orequal to the lower limit, and the depth of the second segment is greater than or equal to half of the crimping width of the core wire crimping portion. The terminal crimping quality assessment methodhas the advantages of having no demand for destroying the sample so as to reduce the production cost, being high in detection efficiency and short in the test period, being able to realize full inspection coverage of the terminal quality, and being suitable for being included in the QC Quality Control) process of mass production.

Description

technical field [0001] The invention relates to the field of terminal crimping, in particular to a terminal crimping quality evaluation device, a terminal crimping quality evaluation method and a terminal crimping system. Background technique [0002] At present, the poor crimping of the terminal of the wire body has always been a major difficulty in improving the quality of the wire body. In the past, the crimping quality of the terminal was evaluated by the pressure (tension) of the terminal and the wire body and the analysis of the terminal section. However, there are the following problems with these two evaluation methods: [0003] 1) The test of the pressure and the analysis of the section of the terminal are destructive tests. The samples after the test cannot be used normally and can only be scrapped, resulting in waste of materials; [0004] 2) The detection efficiency is too low, which seriously affects the production efficiency, and can only be used as a random i...
