Specific embodiment

The utility model is described further with reference to the accompanying drawing.

Embodiment one

As shown in Figure 1, a kind of mobile phone screen mould group testing current jig, including mounting plate 1, survey is set on the mounting plate 1 Mainboard 2 is tried, the mounting plate 1 includes substrate 101 in rectangular shape, and 101 4 side of substrate is equipped with baffle 102 vertically, The testing host 2 is set on the substrate 101 that baffle 102 is enclosed, in setting digital ammeter 4 on any baffle 102, in test Output end lead 3 is set on mainboard 2, the output end lead 3 is followed by through baffle 102 in digital ammeter 4.

Testing host 2 is connected on the substrate 101 that gear 102 surrounds, and digital ammeter 4 is connected to outside baffle 102, test master Plate 2 is equipped with the output end lead 3 of access digital ammeter 4, and mobile phone screen mould group to be measured is placed on test master when use It on plate 2 and is aligned, after the completion of contraposition, test starts, and external power supply is powered to mobile phone screen, and mobile phone screen is normally lighted simultaneously Bring into operation picture, when there is complete white or completely black picture (TN screen is the control of completely black picture, and IPS screen is complete white picture control), The circuit data generated when testing is embodied on digital ammeter 4 by testing host 2 at this time, and tester observes ammeter number Value is confirmed whether, if exceeding control value, to power off immediately beyond control value, protect screen mould group not burn-in, so can be intuitive Understand mould group test electric current size and numerical value, it should be noted that in the present embodiment, to mobile phone screen mould group carry out electric current The method of test belongs to the prior art, such as: those skilled in the art, which understand, knows how should test, and test mode The not inventive point of the utility model and protection main points, details are not described herein again.Meanwhile output end lead 3 is after baffle 102 It will not be wound in other components, easy cleaning carelessly.

Embodiment two

In order to enable digital ammeter 4 is more easily installed on baffle 102, the present embodiment is on the basis of example 1 Bindiny mechanism 5 is increased, referring to fig. 2, the digital ammeter 4 is mounted on baffle 102 by bindiny mechanism 5, the company Connection mechanism 5 includes the pedestal 501 for being embedded at baffle 102, and threaded hole 502 is opened up in pedestal 501, and shell 503 is flexibly connected baffle 102 and cover pedestal 501, screw rod 504 run through shell 503 after be flexibly connected with threaded hole 502, in the screw rod 504 outside shell 503 On set link block 505, digital ammeter 4 is set on link block 505.

Pedestal 501 plays a supportive role on baffle 102, and 503 grafting of shell wraps up pedestal 501 after entering baffle 102, such as This one, when screw rod 502 screw in pedestal 501 after, shell 503 plays a protective role to screw rod 504, pedestal 501, is able to extend it Service life, and screw rod 504, pedestal 501 play the role of extending digital ammeter 4 at a distance from baffle 102, when avoiding work Both sides fever interacts, and staff observes when more convenient test.

Embodiment three

In order to enable the connection of shell 503 and baffle 102 is more firm, the present embodiment increases on the basis of example 2 Plug assembly 6, referring to Fig. 3, the shell 503 is flexibly connected baffle 102 by plug assembly 6, and the plug assembly 6 includes Sphenoid 601, groove 602, guide pile 603, sliding block 604, lug boss 605, the sphenoid 601 is set on shell 503, described Groove 602 is opened in 102 outer surface of baffle, and the guide pile 603 is L-shaped, and two guide piles 603 are symmetrically set in 602 bottom of groove Portion makes two guide piles 603 and class " recessed " structure, the sliding block 604 of two cooperation sphenoids 601 are formed on 602 bottom of groove It is slideably positioned on the groove 602 between two guide piles 603, sphenoid 601 wedges rear-guard movable slider between two sliding blocks 604 It is moved toward close to 603 direction of guide pile, the lug boss 605 of guide pile 603 is closed in establishing on sliding block 604, sets supporting element on shell 503 7。

When needing shell 503 to connect with corresponding baffle 102, control shell 503 makes sphenoid close to baffle 102 Between two sliding blocks 604 in 601 insertion grooves 602, sphenoid 601 drives sliding block 604 respectively toward close to 603 direction of guide pile Movement, lug boss 605 stick into guide pile 603 and fix, and shell 503 is combined with baffle 102 at this time, referring to fig. 2, the weight of shell 503 Power is in inverted T shaped supports support by be set to 503 near-earth surface side of shell, and shell and baffle is avoided to be detached from, when needing shell 503 When separating with baffle 102, shell is moved horizontally, sphenoid 601 is skidded off between two sliding blocks 604 at this time, light desheathing 503, it is designed in this way, compared to more traditional inserting mode, such as pin hole grafting, sphenoid 601 is not directly placed on baffle 102, And shell total amount is supported by supporting element, will not destroy baffle 102, is prolonged the service life and be ensure that work safety.

In order to keep the cooperation of sphenoid and sliding block 604 more smooth, the vertical section of the sphenoid 601 is isosceles trapezoid, The stub end connected with outer casing 503 of the sphenoid 601 sets the inclined-plane wedged for sphenoid 601 on the sliding block 604.

In view of stress balance and integral strength, in the present embodiment, the quantity of the plug assembly 6 is two, and two are inserted Axisymmetrical of the connection device 6 about threaded hole 502.

Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model It encloses, should all cover in the scope of the claims of the utility model.
