Description
Technical field
The utility model relates to auto parts and components manufacture field, specially a kind of pin height.
Background technique
Bonder terminal used in auto-parts, main function are the interfaces as electrical connection or transmission signal,
In automotive connector production process, one of technique is terminal needle inserting, i.e., connecting terminal is inserted into connector shell.Terminal
Including two parts of plastic part and contact pin, contact pin it is different, when assembling, needs for be inserted into plastic part contact pin, and requires modeling
Materials and parts and contact pin do not damage indeformable, and to the normotopia degree of contact pin, height, compression distance etc. has higher requirement.It is existing
High speed contact pin equipment in process of production occasional generate leakage contact pin and insert bad plastic cement defective products the problems such as.
Utility model content
Problem to be solved in the utility model is, the shortcomings that for the above prior art, proposes a kind of contact pin height detection
Device anti-leak-stopping contact pin and can insert bad needle with real-time detection contact pin state.
To solve the above problems, the utility model provides following scheme: a kind of pin height, including test
Reference block, testing needle, probe and laser micrometer, test benchmark block have contact pin collection terminal and test test side, and contact pin is adopted
It is equipped with the through-hole passed through for the testing needle between collection end and test test side, is interspersed with testing needle in each through-hole；Test
The tip that needle is located at test benchmark block contact pin collection terminal is directed at the contact pin position of product to be measured, and testing needle is located at the survey of test benchmark block
The tip for trying test side connects the probe；Laser micrometer is set to the side of test benchmark block, test benchmark block and survey
Side relief hole is equipped on test point, and whether the light of the sending acquired by laser micrometer passes through side relief hole and judge contact pin
Highly.
Further, the contact pin collection terminal of test benchmark block has the inserted terminal with product port match, in the grafting
Limiting groove is set on end, guarantees that collection terminal and product stablize grafting, improves detection accuracy.
Further, test benchmark block bottom is equipped with support base, and support base is convex support base, for fixing test benchmark
Block keeps the stability of detection.
Further, the cross section of through-hole is in rectangle, and the shape of the testing needle is matched with the via hole profile；The survey
Test point quantity is consistent with the number of openings on the reference block.
Further, probe is equipped with probe set, for protecting probe, improves detection sensitivity.
Further, laser micrometer includes signal issuing side and receiving end, and issuing side and receiving end are respectively arranged on test
The two sides of reference block, issuing side issue the side relief hole that signal penetrates test benchmark block and testing needle, and receiving terminal receives signal, read
Access value, judges product fine.
The beneficial effects of the utility model are: the device issues signal beams in real time by laser micrometer and receive can be with
Real-time monitoring contact pin state judges whether terminal is inserted into plastic cement or whether insertion depth accords with by reading the numerical value of sensor
It closes, defective products is filtered out with this, test benchmark block is equipped with limiting slot, and bottom is equipped with the probe on support base and probe
Set all greatly improves detection sensitivity and detection stability, improves work efficiency.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is the utility model application schematic diagram.
In the figure, it is marked as 1, product, 2, test benchmark block, 3, testing needle, 4, probe, 5, laser micrometer.
Specific embodiment
The utility model is further described below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, a kind of pin height, including test benchmark block 2, testing needle 3, probe 4 and Laser Measuring
Micro- instrument 5, test benchmark block 2 have contact pin collection terminal and test test side, are equipped with and supply between contact pin collection terminal and test test side
The through-hole that the testing needle 3 passes through, is interspersed with testing needle 3 in each through-hole；Testing needle 3 is located at 2 contact pin of test benchmark block and adopts
The tip at collection end is directed at the contact pin position of product to be measured, and testing needle 3 is located at the tip connection institute that test benchmark block 2 tests test side
Probe 4 is stated, probe 4 is equipped with probe set；Laser micrometer 5 includes signal issuing side and receiving end, issuing side and reception
End is respectively arranged on the two sides of test benchmark block 2, is equipped with side relief hole on test benchmark block 2 and testing needle 3, and pass through Laser Measuring
Whether the light for the sending that micro- instrument 5 acquires, which passes through side relief hole, judges contact pin height.
When work, 5 signal beams of laser micrometer penetrate 2 side relief hole of test benchmark block, 3 side relief hole of testing needle, this
When base position read sensor numerical value, the numerical value of optical fiber then illustrates that terminal has been inserted into modeling in the range of setting when such
Glue, and contact pin depth meets the requirements；If the numerical value of optical fiber is other than the range of setting, then illustrate terminal be not inserted into plastic cement or
Insertion depth is undesirable, and control system determines that contact pin is bad.
Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art
Say, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic into
Row equivalent replacement, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all
It is included within the scope of protection of this utility model.
