Description
Technical field
The utility model relates to a kind of dimension measuring devices, more particularly to a kind of step drop size of step-like object
Measuring device.
Background technique
The data line both ends of electronic equipment usually respectively have connector to connect two electronic equipments, outside the interface of connector
There is iron-clad in portion, and forming plastic cement external mold is fixed between iron-clad and wire rod, and iron-clad is exposed at the partial insertion electronic equipment pair of plastic cement external mold
The interface answered.Such as USB data line connector, earphone wire terminal are all typical step-like objects.In these data lines, earphone cable
Need the length for being exposed at plastic cement external mold to iron-clad to manage in machining process, that is to say, that need to measure step-like object from
The length that step section is stretched out, and then whether judge it qualified.
Existing management-control method is to be determined as non-defective unit if the length is in comparison tolerance using artificial comparison inspection, no
Then it is determined as defective products, but artificial compare is easy to appear mistake, realizes that measurement data record is more difficult.The length can also be with
It borrows industrial camera and passes through Image measurement, but this method higher cost, be difficult to promote in the lower processing type industry of added value.
To solve the above-mentioned problems, Chinese patent CN204854611U discloses a kind of data cable connector length electric logging device, including base,
Positioning seat, detection module and alarm sounder；It is provided with the locating slot for location data wire terminal on the positioning seat and is used for
Limit the limiting section of data connector metal portion rear end；The detection module is located at the front side position of locating slot, which includes
Spacing is provided with two electricity connection ends side by side, which is electrically connected in aforementioned alarm sounder, two electricity
Property connecting pin rear end be positioned at same perpendicular two detect conducting faces, and its detect conducting face and aforementioned locating slot front end
Keep clearance for insulation；When detection, data cable connector need to be only correspondingly placed into locating slot, data cable connector is acted on by limiting section
Data connector metal portion rear alignment above is formed, if data cable connector metal portion front end abuts two detection conducting faces, is alarmed
Acoustical generator sounding is to prompt length detection qualified, otherwise, it may appear that it is too long fail to lay down, the unqualified phenomenon of too short no prompting sound.
Although the device realizes length detection judgement, but it is more demanding for the size of article to be detected, the ruler of connector to be measured
It is very little must be likely to just be embedded in locating slot in a very small range make connector be connected electricity connection end.This leads to connector
Size may in a qualified margin of tolerance but locating slot can not be embedded in, or electricity connection end can not be connected and misjudged
For unqualified part.
