Abstract
The invention discloses a testing tool of a laser device. The testing tool with a soft plate transmitter optical subassembly (TOSA) comprises a platform, the platform is provided with a limiting groove, a pressing block is arranged above the limiting groove and connected with a pressing device, and the pressing device can drive the pressing block to move along the vertical direction relative to the limiting groove. The testing tool with the soft plate TOSA solves the technical problem that for a long time, TOSA and receiver optical subassembly (ROSA) with soft plates cannot be tested separately. By adopting the testing tool as a testing means, yield rate can be greatly improved, and convenient and fast testing means is provided for production and development.
Description
Technical field
The present invention relates to a kind of laser instrument test fixture, particularly one band adagio TOSA test fixture.
Background technology
For a long time, method of testing for traditional TOSA rests on and is first welded together by the face of weld of the adagio of TOSA with mainboard, and then the parameters of TOSA is tested, this method of testing needs to be welded with the face of weld of mainboard by the face of weld on the adagio of TOSA seriatim on the one hand, and work efficiency is lower; On the other hand, TOSA after adagio welding takes off and easily damages and be not easy to preserve the waste causing TOSA, in order to the testing efficiency to band adagio TOSA can be improved, and the waste reduced TOSA, need a kind of band of design adagio TOSA test fixture badly, solve the technical matters can not carrying out independent test for a long time to TOSA.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency existing in prior art, a kind of band adagio TOSA test fixture is provided.Improve the testing efficiency to TOSA, and reduce the waste to TOSA, solve the technical matters can not carrying out independent test for a long time to TOSA.
In order to realize foregoing invention object, the invention provides following technical scheme:
A kind of band adagio TOSA test fixture, comprise platform, described platform is provided with stopper slot, the top of described stopper slot is provided with briquetting, and described briquetting is connected with hold down gag, and described hold down gag can drive briquetting vertically to move in stopper slot.
Be arranged on stopper slot on platform for being contained in therebetween by adagio; Setting is fixed for compressing adagio with the briquetting above stopper slot, after crimping fixes, tests; The hold down gag connecting briquetting makes briquetting vertically move in stopper slot, to be fixed or to unclamp band adagio TOSA.
Described briquetting is T font, and the shape of described briquetting lower end shape and stopper slot is suitable.
Described briquetting is T font and the shape of briquetting lower end shape and stopper slot is suitable, and such design is convenient to briquetting lower end is extend among stopper slot.
Described device comprises the support be arranged on platform, and described support is vertically provided with threaded hole, is provided with bolt in described threaded hole, and the screw rod end face of described bolt can drive briquetting vertically to move in stopper slot.
After band adagio TOSA is placed in stopper slot, get final product swivel bolt, the screw rod end face of bolt drives briquetting vertically mobile to compress adagio in stopper slot.
Back-moving spring is provided with between described platform and briquetting.
After to be tested, reverse rotation bolt, briquetting flicks by back-moving spring, is taken away by the band adagio TOSA be completed, and put into next device under test from stopper slot.
Described platform is provided with mounting blocks, the upper surface of described mounting blocks and the lower surface of described briquetting are provided with mounting groove, the lower end of described back-moving spring is contained in the mounting groove of described mounting blocks upper surface, and the upper end of described back-moving spring is contained in the mounting groove of described briquetting lower surface.
Mounting groove can prevent back-moving spring from sliding at stressed situation upper/lower positions.
The lower surface of described briquetting is provided with rubber layer, and described rubber layer and briquetting removably connect.
Described rubber layer has wear-resisting material behavior, because rubber layer needs repeatedly to contact with device under test, repeatedly produces friction, if wearing and tearing, then may cause compressing device under test, select rubber layer to be arranged on briquetting lower end, be of value to the serviceable life and raising compression effect that extend briquetting.On the other hand, described rubber layer is connected with briquetting is dismountable, even if rubber layer senile abrasion, and the rubber layer more renewed.
Be provided with gathering sill inside described support, side and the gathering sill of described briquetting are slidably matched.
Described support is aluminum frame.
compared with prior art, beneficial effect of the present invention:
One, the technical matters can not carrying out independent test for a long time to TOSA is solved.
Accompanying drawing illustrates:
