In the present embodiment, the first height H1And the second height H2With a variety of set-up modes:
Embodiment one, the first height H1Meet: H1<L1-d1/2。L1It is when the through-hole 210 is in predeterminated position
When, the maximum distance of the center line of the through-hole 210 and the loading end 11.First hole wall 211 is to the center line
Distance and being equidistant to the center line of the second hole wall 212.It is understood that being said by taking power supply keyhole as an example
It is bright.For example, the design size of power supply keyhole is 1.74 millimeters, i.e. the first hole wall 211 when shell 200 is placed in loading end 11
The distance between second hole wall 212 is 1.74 millimeters.With loading end 11 for benchmark face, the design position of the center line of power supply keyhole
2.6 millimeters are set to, i.e. height of the center line of power supply keyhole apart from loading end 11 is 2.6 millimeters.At this point, due in through-hole 210
Preparation process in can have error so that the center line for the through-hole 210 being located on shell 200 can permit there are deviation,
Under the deviation, the power key being assemblied in the through-hole 210 still can be with circuit board electrical connection.The deviation include the upper deviation and under
Deviation, for example, the upper deviation be+0.03 millimeter, lower deviation be -0.03 millimeter, i.e., the center line of power supply keyhole to loading end 11 away from
It is between 2.57 millimeters to 2.63 millimeters from range.Similarly, there is also certain deviations, i.e. the first hole wall 211 for the size of through-hole 210
There is also certain deviations for the distance between second hole wall 212.The deviation also includes the upper deviation and lower deviation, such as the upper deviation
It is+0.03 millimeter, lower deviation is also -0.03 millimeter.It is understood that when considering the deviation, the first hole wall 211 and second
The distance between hole wall 212 range is 1.71 millimeters to 1.77 millimeters.So when the through-hole 210 is in predeterminated position, institute
The maximum distance of the center line and the loading end 11 of stating through-hole 210 is 2.63 millimeters, i.e. L1=2.63 millimeters.In addition, d1It is institute
State the minimum qualifying distance between the first hole wall 211 and second hole wall 212, i.e. d1It is 1.71 millimeters.At this point, working as through-hole
The height of 210 the first hole wall 211 to loading end 11 is higher than the first height H1When, the periphery of through-hole 210 will be held in test department
22.At this point, test department 22 can not protrude into through-hole 210, so that detecting jig 100 can be by the first hole wall 211 to loading end 11
Height be higher than the first height H1Through-hole 210 all detected, and be determined as undesirable shell 200, that is, avoid undesirable
There is missing inspection in shell 200.
Further, H1Also meet: H1≥L2-d2/ 2, L2It is the through-hole when the through-hole 210 is in predeterminated position
The minimum range of 210 center line and the loading end 11.That is, L2=2.57 millimeters.d2First hole wall 211 with it is described
Maximum qualifying distance between second hole wall 212, i.e. d2It is 1.77 millimeters.It is understood that when the first detection faces 221 are to holding
The height H of section 111Meet: H1≥L2-d2When/2, minimum altitude of first detection faces 221 apart from loading end 11 is L2-d2/2。
In addition, minimum altitude of first hole wall 211 apart from loading end 11 is also L2-d2/ 2, so, the minimum altitude apart from loading end 11
The through-hole 210 of the first hole wall 211 test department 22 can just be made to protrude into.However, when the height of the first detection faces 221 to loading end 11
Degree meets: H1<L2-d2When/2, the minimum through-hole 210 of height of first hole wall 211 apart from loading end 11 can not make test department 22
It protrudes into, most of qualified shell 200 is mistakenly detected into bad products so as to cause detection jig 100.So by setting
Set H1≥L2-d2/ 2 can accurately be detected qualified shell 200 is effectively ensured.
Further, second height is H2, H2Meet: H2>L2+d1/2。L2It is when the through-hole 210 is in default position
When setting, the minimum range of the center line of the through-hole 210 and the loading end 11, i.e. L2=2.57 millimeters.When the of through-hole 210
Two hole walls 212 to loading end 11 height less than the second height H2When, the periphery of through-hole 210 will be held in test department 22, at this point,
Test department 22 can not protrude into through-hole 210, so that the height of the second hole wall 212 to loading end 11 is lower than the second height H2It is logical
Hole 210 all detected, and be determined as undesirable shell 200.So passing through the second detection faces 222 of setting to loading end 11
Height H2Meet: H2>L2+d1When/2, it is ensured that the height of the second hole wall 212 to loading end 11 is lower than the first height H1's
Through-hole 210 all detected.
Embodiment two, unlike embodiment one: H1It does not need to meet: H1≥L2-d2/ 2, but H2Also meet: H2
≤L1+d2/ 2, d2It is the maximum qualifying distance between first hole wall 211 and second hole wall 212.It is understood that
As the height H of the second detection faces 222 to loading end 112Meet: H2≤L1+d2When/2, the second detection faces 222 are apart from loading end 11
Minimum altitude be L1+d2/2.And minimum altitude of second hole wall 212 apart from loading end 11 is also L1+d2/ 2, so, the second hole
The through-hole 210 of minimum altitude of the wall 212 apart from loading end 11 can just make test department 22 protrude into.However, when the second detection
The height of face 222 to loading end 11 meets: H2>L1+d2When/2, the minimum through-hole of height of second hole wall 211 apart from loading end 11
210 cannot also accommodate test department 22, mistakenly detect into most of qualified shell 200 not so as to cause detection jig 100
Good product.So by the way that H is arranged2≤L1+d2/ 2 are accurately detected qualified shell 200 is effectively ensured.
Embodiment three, unlike embodiment one and embodiment two: the first height H1It is described first
Maximum distance when hole wall 211 is in predeterminated position between the loading end 11.The second height H2For second hole
