Abstract
The utility model discloses a test fixture, comprises a test box and a fixing device; the fixing device is provided with a placement position of a display module group to be tested; the fixing device is detachably arranged on the test box. As the test fixture of the utility model comprises the detachably connected test box and fixing device, the placement position of the display module group to be tested on the fixing device can be machined based on the size of the display module group. Therefore, when different display module groups are measured, the fixing device, rather than the entire test fixture, is replaced. The test fixture of the utility model is simple in manufacturing and low in cost, which has significant economic benefits and is convenient to use.
Description
Technical field
The utility model relates to a kind of test fixture.
Background technology
Mobile phone has become the indispensable communication tool of current social people, and liquid crystal display module (LCDmodule is called for short LCM) is a vitals on the mobile phone.For guaranteeing the quality of mobile phone, generally all need the liquid crystal display module of mobile phone is tested.Existing test fixture is to offer one to show the module rest area on the surface of a testing cassete, and the size of this rest area is decided according to the size that shows module.But owing to show that the module rest area is to offer on the surface of testing cassete, so at different demonstration modules, that the user just needs to make is different, show the corresponding test fixture of module size with this, therefore existing test fixture cost is very high.
Summary of the invention
The utility model is exactly in order to overcome above deficiency, to have proposed a kind of test fixture cheaply.
Technical matters of the present utility model is solved by following technical scheme: a kind of test fixture, comprise testing cassete, also comprise stationary installation, described stationary installation is provided with demonstration module to be measured and places the position, and described stationary installation is removably mounted on the described testing cassete.
Preferably, be provided with test suite in the described testing cassete, described test suite comprises the connecting circuit plate, and described test fixture also comprises and being used for the golden finger of demonstration module to be measured and the steady arm of the accurate contraposition of connecting circuit plate.
Described steady arm comprises briquetting, be positioned at the opening on the stationary installation and be positioned at least two positioning holes on testing cassete surface, is provided with locking device in the described briquetting, and described locking device passes on the positioning hole that opening is fixed on testing cassete.
Also comprise bearing and overlay bar, described bearing is positioned at the both sides of described connecting circuit plate, and the described bar that overlays can slide up and down on the fixing described bearing.
Also comprise and be used for moving the pressing tongs that overlays bar.
The beneficial effect that the utility model is compared with the prior art is: test fixture of the present utility model is because comprise testing cassete and the stationary installation that removably connects, and the demonstration module to be measured on the stationary installation is placed the position and can be made according to the size that shows module.Like this, when different demonstration modules is measured, can only change stationary installation and get final product, need not whole test fixture is changed, test fixture of the present utility model is with low cost, remarkable in economical benefits, manufacturing are simple, easy to use.
Test fixture of the present utility model also comprises steady arm, being connected between the golden finger that can adjust demonstration module to be measured by steady arm quickly and easily and the connecting circuit plate, and make accurate, the of the present utility model test fixture of both contrapositions operate flexibly, reliable.
Description of drawings
Fig. 1 is a test fixture structural representation of the present utility model;
Fig. 2 is the structural representation of the stationary installation of the utility model test fixture;
Fig. 3 is the panel synoptic diagram of the testing cassete of the utility model test fixture.
Embodiment
Also in conjunction with the accompanying drawings the utility model is described in further details below by concrete embodiment.
Shown in Fig. 1,3, a kind of test fixture comprises testing cassete 1, stationary installation 2, be provided with test suite in the described testing cassete 1, described test suite comprises the connecting circuit plate, this connecting circuit plate passes slotted eye 14 and is placed on testing cassete 1 surface, described stationary installation 2 is provided with demonstration module to be measured and places position 21, and described stationary installation 2 is removably mounted on the described testing cassete 1.Described demonstration module to be measured is preferably mobile phone liquid crystal display module.After demonstration module to be measured being placed on demonstration module placement to be measured position 21, the golden finger of demonstration module to be measured is electrically connected with the connecting circuit plate.As shown in Figure 2, the demonstration module placement to be measured position 21 on the stationary installation 2 can make according to the size that shows module.Like this, when different demonstration modules is measured, can only change stationary installation 2 and get final product, need not whole test fixture is changed, test fixture of the present utility model is with low cost, remarkable in economical benefits, manufacturing are simple, easy to use.
As shown in Figure 1, 2, described test fixture also comprises steady arm, and described steady arm is used for the golden finger of demonstration module to be measured and the accurate contraposition of connecting circuit plate.Described steady arm comprises briquetting 3, be positioned at the opening 22 on the stationary installation and be positioned at least two positioning holes 11 on testing cassete surface, is provided with locking device 31 in the described briquetting, and described locking device 31 passes on the positioning hole 11 that opening 22 is fixed on testing cassete.
By steady arm, being connected between the golden finger that test fixture of the present utility model can be adjusted demonstration module to be measured quickly and easily and the connecting circuit plate, and make both contrapositions accurate.
Shown in Fig. 1,3, described testing cassete 1 also comprises linear bearing 19 and overlays bar 18, described linear bearing 19 is fixed on the both sides of the connecting circuit plate rest area 17 of testing cassete 1 by linear bearing mounting hole 15, the described bar 18 that overlays is fixed on the linear bearing 19, and can move up and down along linear bearing 19.After the golden finger with demonstration module to be measured is placed on the connecting circuit plate, the user can move to lowermost end with overlaying bar 18, the golden finger and the connecting circuit plate of demonstration module to be measured are forced together, and both are closely fixing, thereby the golden finger of demonstration module to be measured reliably is connected with the connecting circuit plate.For easy to use, testing cassete 1 can comprise also and be used for moving the pressing tongs (not shown) that overlays bar that described pressing tongs is fixed on the testing cassete 1 by the pressing tongs mounting hole 16 on testing cassete 1 panel.Described pressing tongs can be automatically moves to lowermost end and the golden finger and the connecting circuit plate of demonstration module to be measured is forced together overlaying bar 18.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
