Abstract
The utility model discloses a kind of test fixture of lightning interface SD card reader, can it substitutes existing SD card and constantly plugs on apple equipment, normally read and write SD card to test apple equipment.Wherein SD card inserts in SD deck of the present utility model, need not repeatedly plug SD card, and uses the utility model to go to plug the lightning interface on apple equipment.Such SD card can not damage, and reduces testing cost.Simultaneously in order to avoid the lightning interface on apple equipment is scratched, the lightning interface thickness design on the utility model test fixture, between 13.8-14.6mm, can either ensure good electrical connection, can not scratch again the golden finger of apple equipment lightning interface.
Description
Technical field
The present invention relates to a kind of test fixture of lightning interface SD card reader, belong to Electronic Testing field.
Background technology
The Lightning Dock interface of Apple, translator of Chinese is lightning interface, is widely used in iPhone5 and iPod of its a new generation, iPad product.Conveniently user reads or writes traditional SD card by lightning interface, and Apple is also proposed lightning interface SD card reader, and this converter one end is SD deck, and the other end is lightning interface.
In order to whether the function detecting apple equipment read-write SD card is normal, the test of existing lightning interface SD card reader, be the SD deck using real SD card directly to insert lightning interface SD card reader, then the lightning interface end of lightning interface SD card reader is connected on apple equipment.Carry out testing equipment can correctly read and write by constantly plugging SD card.Modern production uses automated test device in a large number, and plug repeatedly can damage SD card, makes testing cost higher.Constantly can certainly plug the lightning interface of SD card reader, but cut can be left on the lightning interface of apple equipment like this.
Summary of the invention
Goal of the invention: the present invention proposes a kind of test fixture of lightning interface SD card reader, tests the performance of apple equipment read-write SD card at low cost when not damaging SD card.
Technical scheme: the present invention proposes a kind of test fixture of lightning interface SD card reader, comprises pcb board, is provided with the golden finger of lightning interface at pcb board, pcb board is also provided with SD deck, be connected between golden finger with SD deck by the wiring on pcb board.
Preferably, the thickness of described pcb board is between 13.8-14.6mm.
Preferably, described golden finger side is also provided with write-protect switch.
Can beneficial effect: the present invention substitutes existing SD card and constantly plugs on apple equipment, normally read and write SD card to test apple equipment.Wherein SD card inserts in SD deck of the present invention, need not repeatedly plug SD card, and uses the present invention to go to plug the lightning interface on apple equipment.Such SD card can not damage, and reduces testing cost.Simultaneously in order to avoid the lightning interface on apple equipment is scratched, the lightning interface thickness design on test fixture of the present invention, between 13.8-14.6mm, can either ensure good electrical connection, can not scratch again the golden finger of apple equipment lightning interface.
Accompanying drawing explanation
Fig. 1 is the use principle figure of the test fixture of a kind of lightning interface of the present invention SD card reader;
Fig. 2 is the top view of the test fixture of a kind of lightning interface of the present invention SD card reader;
Fig. 3 is the sectional view of the test fixture of a kind of lightning interface of the present invention SD card reader.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
As shown in Figure 1, the test fixture of tested lightning interface SD card reader is fixed on tester by installing hole 4, is mechanically connected with tester, and SD card inserts in the SD draw-in groove 3 of test fixture.
As shown in Figure 2 to Figure 3, pcb board 1 is in T shape.Pcb board 1 narrower while be provided with the golden finger 2 of lightning interface.The another side of the pcb board 1 relative with golden finger 2 is provided with SD deck 3, and this SD deck 3 and golden finger 2 are arranged on the surface, the same side of pcb board 1.SD deck 3 opening golden finger 2 dorsad.
Test fixture needs to be fixed on tester, during test, SD card inserts in SD deck 3, test fixture is under the driving of tester, and can golden finger 2 is constantly inserted in the lightning interface of tested apple equipment normally read and write SD card to test apple equipment, and read-write speed.Such SD card does not just need repeatedly to plug, and is also just not easy to damage.Even if damage, be also that test fixture damages, and the cost of test fixture is far below SD card.
In order to fixing test fixture, be provided with installing hole 4 between golden finger 2 and SD deck 3, these installing holes 4 are distributed in the both sides of pcb board 1 symmetrically, better fix the effect of this test fixture to facilitate tester.
In addition, in order to prevent the lightning interface of test fixture when with apple equipment connection, scratch the lightning interface of apple equipment, need pcb board 1 thickness that selection one is suitable, when making test fixture constantly insert apple equipment, can either ensure that contact is good, the lightning interface of apple equipment can not be scratched again.A large amount of tests through as shown in table 1:
Table 1
From the test data of table 1, the thickness of pcb board 1 performance between 13.8-14.6mm is best, scratch quantity and loose contact quantity all less.
Also be provided with write-protect switch 5 in the edge of golden finger side, be convenient to test writing protection function.
Claims (3)
1. a test fixture for lightning interface SD card reader, is characterized in that, comprise pcb board, is provided with the golden finger of lightning interface at pcb board, and pcb board is also provided with SD deck, is connected between golden finger with SD deck by the wiring on pcb board.
2. the test fixture of lightning interface SD card reader according to claim 1, it is characterized in that, the thickness of described pcb board is between 13.8-14.6mm.
3. the test fixture of lightning interface SD card reader according to claim 1 and 2, it is characterized in that, described golden finger side is also provided with write-protect switch.
