Description
Technical field
The present invention relates to a kind of laser test fixture, more particularly to a kind of band adagio TOSA test fixtures.
Background technology
For a long time, method of testing for traditional TOSA rests on and first welds together TOSA adagio with the solder side of mainboard, then the parameters again to TOSA are tested, on the one hand this method of testing needs seriatim to be welded the solder side and the solder side of mainboard on TOSA adagio, and operating efficiency is relatively low；On the other hand, TOSA after adagio is welded, which is removed, to be easily damaged and is not easy to preserve the waste for causing TOSA, in order to be able to improve to the testing efficiency with adagio TOSA, and reduce the waste to TOSA, need a kind of band adagio TOSA test fixtures of design badly, solve that for a long time TOSA can not be carried out the technical problem of independent test.
The content of the invention
It is an object of the invention to overcome in the presence of prior art above-mentioned not enough there is provided a kind of band adagio TOSA test fixtures.The testing efficiency to TOSA is improved, and reduces the waste to TOSA, solves that for a long time TOSA can not be carried out the technical problem of independent test.
In order to realize foregoing invention purpose, the invention provides following technical scheme：
It is provided with a kind of band adagio TOSA test fixtures, including platform, the platform above stopper slot, the stopper slot and is provided with briquetting, the briquetting is connected with hold-down gear, and the hold-down gear can drive briquetting vertically to be moved in stopper slot.
The stopper slot being arranged on platform is used to accommodate adagio therebetween；Set and be fixed with the briquetting above stopper slot for compressing adagio, after crimping is fixed, tested；The hold-down gear of connection briquetting makes briquetting vertically be moved in stopper slot, to be fixed or unclamp band adagio TOSA.
The briquetting is in T fonts, and briquetting lower end shape is adapted with the shape of stopper slot.
The briquetting is adapted in T fonts and briquetting lower end shape with the shape of stopper slot, and such design is easy to make briquetting lower end extend among stopper slot.
Described device includes the support being arranged on platform, and the support, which is vertically provided with screwed hole, the screwed hole, is provided with bolt, and the screw rod end face of the bolt can drive briquetting vertically to be moved in stopper slot.
After it will be placed in adagio TOSA in stopper slot, you can swivel bolt, the screw rod end face of bolt drives briquetting vertically to move to compress adagio in stopper slot.
Back-moving spring is provided between the platform and briquetting.
It is to be tested finish after, reversely rotate bolt, briquetting flicks, the band adagio TOSA being completed is taken away from stopper slot, and be put into next device under test by back-moving spring.
Mounting blocks are provided with the platform, the upper surface of the mounting blocks and the lower surface of the briquetting are provided with mounting groove, the lower end of the back-moving spring is contained in the mounting groove of the mounting blocks upper surface, and the upper end of the back-moving spring is contained in the mounting groove of the briquetting lower surface.
Mounting groove can prevent that back-moving spring position in the case of stress from sliding.
The lower surface of the briquetting is provided with rubber layer, and the rubber layer is detachably connected with briquetting.
The rubber layer has wear-resisting material property, because rubber layer needs to contact with device under test repeatedly, is iteratively produced friction, if abrasion, it may then lead to not compress device under test, selection rubber layer is arranged on briquetting lower end, the service life for being beneficial to extend briquetting compresses effect with raising.On the other hand, the rubber layer is removably connected with briquetting, even if rubber layer senile abrasion, the rubber layer more renewed.
Gathering sill is provided with the inside of the support, side and the gathering sill of the briquetting are slidably matched.
The support is aluminum frame.
Compared with prior art, beneficial effects of the present invention：
First, the technical problem of independent test can not be carried out to TOSA for a long time by solving.
Brief description of the drawings：
Fig. 1 is the front view of the invention with adagio TOSA test fixtures.
Marked in figure：1- platforms, 2- stopper slots, 3- briquettings, 4- supports, 5- screwed holes, 6- bolts, 7- screw rods, 8- back-moving springs, 9- mounting blocks, 10- mounting grooves, 11- rubber layers, 12- gathering sills.
Embodiment
With reference to test example and embodiment, the present invention is described in further detail.But this should not be interpreted as to the scope of above-mentioned theme of the invention and be only limitted to following embodiment, it is all that the scope of the present invention is belonged to based on the technology that present invention is realized.
Embodiment 1
As shown in figure 1, a kind of band adagio TOSA test fixtures, including platform 1, stopper slot 2 is provided with the platform, briquetting 3 is provided with above the stopper slot, the briquetting 3 is connected with hold-down gear, and the hold-down gear can drive briquetting 3 vertically to be moved relative to stopper slot 2.
Setting stopper slot 2 on the platform 1 is used to accommodate adagio therebetween；Set is used to crimp with adagio to be fixed with the briquetting 3 of the top of stopper slot 2, after crimping is fixed, is tested；The hold-down gear of connection briquetting 3 is vertically moved for briquetting 3 relative to stopper slot 2, is crimped fixed with briquetting 3 or is unclamped with adagio TOSA.
The briquetting 3 is in T fonts, and briquetting lower end shape is adapted with the shape of stopper slot 2.
