Description
Technical field
The present invention relates to the cubing technical field of electronic component, especially a kind of adjustable quantitative determination dynamometer.
Background technology
Connector finished product belongs to conventional detection before dispatching from the factory to the repetition measurement of contact separating force, and the detection of prior art is to use weight
Code gravity mode is tested the separating force of connector contact one by one, in test process, because human eye difficulty or ease are observed
Mating surface, detection efficiency is relatively low and easily test leakage phenomenon occurs.Additionally, due to counterweight detection mode be gravity detection, Weight gravity with
Contact mating surface necessarily be in vertical, cause detection inconvenience.Especially for the periodic inspection work of product of having installed
In, because the installation direction of connector is different, causing Weight gravity to detect cannot implement.Have at present
Tri- kinds of inventions of ZL200620057696.2, ZL200420004656.2, CN205120290U and a kind of inventions of CN105181206A
Patent discloses the technology of separating force detection.But first two is for detecting the plug between connector weldering wire end plug and socket
Power, and latter two is the separating force detection for single contact, it is impossible to meet the multi-faceted contact separating force of finished product connector
Repetition measurement.
The content of the invention
A kind of adjustable quantitative determination dynamometer that the purpose of the present invention is directed to the deficiencies in the prior art and provides, this
Invention limits the displacement of reference test bar to control reference test bar pressure using spring is set between shell and reference test bar by adjusting nut
The elastic force of contracting spring, so as to detect the separating force of contact by controlling elastic force.The present invention has simple structure, adjustment calibration
The advantage that convenient and not examined direction limits.
Realizing the concrete technical scheme of the object of the invention is：
A kind of adjustable quantitative determination dynamometer, its feature includes that shell, reference test bar, collet, adjusting nut, standard are surveyed
Test point, spring and end cap, the shell are that interior setting tests rod aperture and the first spring base, the tubular elements of peripheral hardware end cap screw thread, test
Bar is provided with external screw thread, is provided with the rod-like element of second spring seat therebetween for one end is provided with chuck joint, the other end；
In the test rod aperture of shell, spring is located at the first spring base of shell and the second spring of reference test bar for the reference test bar
Between seat, end cap is engaged in shell termination through reference test bar spiral-lock with end cap screw thread, and collet is fixed on the chuck of reference test bar
On joint, on the external screw thread of reference test bar, standard testing pin is in collet for adjusting nut.
The present invention limits the displacement of reference test bar to control using spring is set between shell and reference test bar by adjusting nut
The elastic force of reference test bar compression spring processed, so as to detect the separating force of contact by controlling elastic force.The present invention has structure letter
Single, the advantage of convenient and not examined direction limitation is calibrated in adjustment.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
Refering to Fig. 1, the present invention includes shell 1, reference test bar 2, collet 3, adjusting nut 4, standard testing pin 5, spring 6
And end cap 7, the shell 1 sets in tests the spring base 12 of rod aperture 11 and first, the tubular elements of peripheral hardware end cap screw thread 13, reference test bar
2 are provided with external screw thread 22, are provided with the rod-like element of second spring seat 23 therebetween for one end is provided with the chuck joint 21, other end；
In the test rod aperture 11 of shell 1, spring 6 is located at first spring base 12 and reference test bar 2 of shell 1 to the reference test bar 2
Second spring seat 23 between, end cap 7 is engaged in the termination of shell 1 through the spiral-lock of reference test bar 2 with end cap screw thread 13, collet
3 are fixed on the chuck joint 21 of reference test bar 2, and on the external screw thread 22 of reference test bar 2, standard testing pin 5 is located at adjusting nut 4
In collet 3.
Embodiment：
Preparation
The present invention is that the technical scheme of connector contact separating force is detected using elastic force, when the contact of connector to be detected
It is determined that after, with get ready with contact match standard testing pin 5 and be clamped on collet 3；Determine to be intended to according to design requirement
Detect the separation force value of contact；The present invention is adjusted on standard tension machine and calibrated by adjusting nut 4；
The test of contact separating force
Refering to Fig. 1, shell 1 is held, standard testing pin 5 is directed at the contact to be detected, applying one in the end of reference test bar 2 pushes away
Power, makes standard testing pin 5 insert the contact to be detected；Hold shell 1 to be exerted a force to the direction away from contact, due to reference test bar
2 are connected through collet 3, standard testing pin 5 with contact, and reference test bar 2 will not be moved, the shifting with shell 1 relative to reference test bar 2
Dynamic, the spring 6 between the first spring base 12 of shell 1 and the second spring seat 23 of reference test bar 2 is pressurized and is converted to elastic force, bullet
The elastic force of spring 6 is the separating force between standard testing pin 5 and contact, as shell 1 is continued to move to relative to reference test bar 2,
The separating force is gradually increased, until the end face of shell 1 is touched with the adjusting nut 4 on reference test bar 2, is now applied to standard testing
Separating force between pin 5 and contact reaches setting value, if standard testing pin 5 is separated with contact during this period, the desire
Detect contact separating force it is unqualified, if standard testing pin 5 is not separated with contact, the contact to be detected divide
It is qualified from power.
The present invention detects the separating force of contact using elastic force, is elastic force detection, is with the maximum difference that gravity is detected
Do not limited by orientation, be particularly suited for the occasion of finished product connector separating force repetition measurement, the contact that different angles are set can be solved
The separating force detection of part.
The present invention can change dynamometry scope of the invention by changing the spring 6 of different coefficient of elasticity.
Refering to Fig. 1, the present invention is by adjusting distance of the adjusting nut 4 relative to the upper end cover 7 of shell 1, you can change spring 6
Stroke and elastic force, so as to meet the detection to different contact separating forces.
The present invention has detection highly versatile, is easy to regulation calibration and testing efficiency is high.Especially solve connection of having installed
The defect of maintenance and the reinspection inconvenience of device product.
Refering to Fig. 1, the profile of shell of the invention 1 and the composition form of a stroke or a combination of strokes of reference test bar 2 is easy to carry, conveniently operates.
