Abstract
The invention discloses a test fixture of a lightning dock-to-USB (Universal Serial Bus) converter. The test fixture is arranged between testing equipment and the lightning dock-to-USB converter so as to prevent direct contact between the testing equipment and the converter. Preferably, the width of a PCB (Printed Circuit Board) at the side of a USB golden finger can adapt to a USB interface of the converter, so that the reliable electric connection is guaranteed, and the plastic shell of a USB plug of the converter cannot be scratched. A signal wire and a power wire between the USB golden finger and a USB master port are respectively placed on the upper and lower surfaces of the PCB, and thus, the interference between a power supply and a signal is avoided.
Description
Technical field
The present invention relates to the test fixture that a kind of lightning interface turns the USB converter, belong to field tests.
Background technology
Apple issued new Lightning Dock interface on September 12nd, 2012, and translator of Chinese is the lightning interface, was used for its iPhone5 of new generation and iPod, iPad product.In order to facilitate the user to be connected with traditional USB interface, Apple has also released the lightning interface and has turned the USB converter, and this converter one end is USB interface, and the other end is the lightning interface.
Existing lightning interface turns the test of USB breakout box, is that testing tool uses USB plug directly to insert the USB end that the lightning interface turns the USB breakout box.Automated test device is used in modern production in a large number, and because there is iron-clad in the USB plug periphery, the plastic housing outward appearance damage that often causes converter USB plug periphery in measured object is inserted in robotization.
Summary of the invention
Goal of the invention: the present invention proposes the test fixture that a kind of lightning interface turns the USB converter, can avoid scratching the plastic housing of the USB plug of converter.
Technical scheme: causing the possible reason of the peripheral plastic housing damage of converter USB plug a lot, may be that the USB interface width is excessive, or thickness be blocked up, may be also that width and thickness are all excessive.Made for this reason the thickness width all different pcb board carry out actual test, test result such as table one.
Table one
Find out width 11.9-12.2mm from test result, the pcb board of thickness 2.0-2.1mm can guarantee few scuffing quantity, guarantees again that the interface contact is good simultaneously.
Therefore the technical solution used in the present invention is the test fixture that a kind of lightning interface turns the USB converter, comprise pcb board, be provided with the USB golden finger in pcb board one side, the pcb board opposite side relative with the USB golden finger is provided with female mouthful of USB, be connected by the wiring on pcb board between female mouthful of USB and USB golden finger, the pcb board width of described USB golden finger one side is 11.9-12.2mm, thickness 2.0-2.1mm.
As a further improvement on the present invention, the pcb board width of described USB golden finger one side is 12mm, and thickness is 2mm.The power lead that is connected between female mouthful of described USB and USB golden finger is positioned at the pcb board lower surface, and signal wire is positioned at the pcb board upper surface.Power lead and signal wire lay respectively at the different surfaces of pcb board, avoid interference each other.Also be provided with mounting hole on described pcb board, be convenient to this test fixture is fixed on testing apparatus.
Beneficial effect: the present invention is arranged on testing apparatus and the lightning interface turns between the converter of USB, avoids testing apparatus directly to contact with converter.The pcb board width of preferred USB golden finger side can be adaptive with the USB interface of converter, both guaranteed reliable electrical connection, can not scratch again the plastic housing of the USB plug of converter.Signal wire between female mouthful of USB golden finger and USB and the wiring of power lead lay respectively at the upper and lower surface of pcb board, have avoided the interference between power supply and signal.

Embodiment
Below in conjunction with the drawings and specific embodiments; further illustrate the present invention; should understand these embodiment only is used for explanation the present invention and is not used in and limits the scope of the invention; after having read the present invention; those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention, and for example female mouthful of lower surface that is arranged on pcb board of USB also belongs to protection scope of the present invention.
Embodiment one
As shown in Figure 1, tested lightning interface turns the USB converter and is arranged on testing tool, and with the testing tool mechanical connection, the lightning interface of converter is connected on other signal sources.Testing tool is connected to the female mouth 3 of USB of test fixture by the USB cable.Test fixture is fixed on testing tool by mounting hole 4.
To shown in Figure 4, pcb board 1 is rectangle as Fig. 2, and pcb board width X is 12mm, and thickness Y is 2mm.The narrower one side of pcb board 1 is provided with USB golden finger 2, and the width X on this side narrow limit is 12mm.The another side of the pcb board 1 relative with USB golden finger 2 is provided with female mouthful 3 of USB, female mouthful 3 upper surface that is arranged on pcb board 1 of this USB, and opening upwards, and can be connected with the USB cable.USB is connected by the power lead 7 that is positioned at pcb board 1 lower surface with the power contact of USB golden finger 2 for female mouthful 3.Signalling contact is connected by the signal wire 6 that is positioned at pcb board 1 upper surface.Test fixture need to be fixed on testing tool, and under the driving of testing tool, USB golden finger 2 is inserted into the USB end that tested lightning interface turns the USB converter.For the fixing test fixture, be provided with mounting hole 4 at pcb board 1 near the position of USB golden finger 2, also offered two breach 5 in this mounting hole 4 both sides, better fix the effect of this test fixture to facilitate testing tool.USB is fixed on pcb board 1 by two fixed orifices 8 that are positioned at its both sides for female mouthful 3.
Embodiment two
Described pcb board width X is 11.9mm, and thickness Y is 2.05mm, and other parts are identical with embodiment one.
Embodiment three
Described pcb board width X is 12.2mm, and thickness Y is 2.1mm, and other parts are identical with embodiment one.
