Abstract
The invention discloses a testing clamp for a lightning interface SD card reader. The testing clamp replaces an SD card to be plugged into or unplugged repeatedly from Apple equipment so as to test whether the Apple equipment normally read and write the SD card or not. The SD card is inserted into an SD card base and does not need to be plugged or unplugged repeatedly, and instead the testing clamp is used for being plugged into or unplugged from a lightning interface in the Apple equipment. In this way, the SD card will not be damaged, and the testing cost is reduced. Meanwhile, in order to protect the lightning interface in the Apple equipment from being scratched, the thickness of a lightning interface in the testing clamp is designed to be from 13.8 mm to 14.6 mm, good electrical connection can be guaranteed, and besides golden fingers of the lightning interface in the Apple equipment will not be scratched.
Description
Technical field
The test fixture that the present invention relates to a kind of lightning interface SD card reader, belongs to Electronic Testing field.
Background technology
The Lightning Dock interface of Apple, translator of Chinese is lightning interface, is widely used in its iPhone5 of new generation and iPod, iPad product.In order to facilitate user to read or write traditional SD card by lightning interface, Apple has also released lightning interface SD card reader, and this converter one end is SD deck, and the other end is lightning interface.
Whether normal in order to detect the function of apple equipment read-write SD card, the test of existing lightning interface SD card reader, be to use real SD card directly to insert the SD deck of lightning interface SD card reader, then the lightning interface end of lightning interface SD card reader is connected on apple equipment.Can carry out testing apparatus correctly read and write by continuous plug SD card.Modern production is used automated test device in a large number, and plug repeatedly can damage SD card, makes testing cost higher.Can certainly constantly plug the lightning interface of SD card reader, but can on the lightning interface of apple equipment, leave cut 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, the performance of testing at low cost apple equipment read-write SD card in the situation that 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 on one side the golden finger of lightning interface at pcb board, be also provided with SD deck on pcb board, between golden finger and SD deck, is connected by the wiring on pcb board.
Preferably, the thickness of described pcb board is between 13.8-14.6mm.
Preferably, described golden finger one side is also provided with write-protect switch.
Beneficial effect: can 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, needn't repeatedly plug SD card, and uses the present invention to remove to plug the lightning interface on apple equipment.SD card can not damage like this, has reduced testing cost.While is scratched for fear of the lightning interface on apple equipment, and 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.
Brief description of the drawings
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 vertical 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.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment is only not used in and limits the scope of the invention for the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the amendment of the various equivalent form of values of the present invention.
As shown in Figure 1, the test fixture of tested lightning interface SD card reader is fixed on testing tool by mounting hole 4, and with testing tool mechanical connection, 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.The narrower one side of pcb board 1 is 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 openings golden finger 2 dorsad.
Test fixture need to be fixed on testing tool, when test, SD card inserts in SD deck 3, test fixture is under the driving of testing tool, and can golden finger 2 is constantly inserted in the lightning interface of tested apple equipment normally read and write SD card with test apple equipment, and read-write speed.SD card just does not need repeatedly to plug like this, 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.
For fixing test fixture, between golden finger 2 and SD deck 3, be provided with mounting hole 4, these mounting holes 4 are distributed in the both sides of pcb board 1 symmetrically, to facilitate testing tool better to fix the effect of this test fixture.
In addition, for the lightning interface that prevents test fixture is when with apple equipment connection, scratch the lightning interface of apple equipment, need to select suitable pcb board 1 thickness, when making test fixture constantly insert apple equipment, can either ensure that contact is good, can not scratch again the lightning interface of apple equipment.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 the best between 13.8-14.6mm, scratches quantity and loose contact quantity all less.
Edge in golden finger one side is also provided with write-protect switch 5, is convenient to test writing protection function.
Claims (3)
1. a test fixture for lightning interface SD card reader, is characterized in that, comprises pcb board, is provided with the golden finger of lightning interface at pcb board on one side, is also provided with SD deck on pcb board, between golden finger and SD deck, is connected by the wiring on pcb board.
2. the test fixture of lightning interface SD card reader according to claim 1, is characterized in that, the thickness of described pcb board is between 13.8-14.6mm.
