Abstract
The utility model discloses a test fixture for a converter used for converting a lightning port into a USB interface, wherein the test fixture is arranged between equipment under test and the converter used for converting a lightning port into a USB interface so as to prevent the equipment under test from directly contacting with the converter. Preferably, the width of a PCB board on the golden-finger side of USB equipment is matched with the USB interface of the converter. Therefore, the reliable electrical connection is ensured, while the plastic shell of the USB plug of the converter is protected from being scratched. The arrangements of a signal line and a power line between the golden-finger part of the USB equipment and the female port of the USB equipment are positioned on the upper and lower surfaces of the PCB board respectively. Therefore, the interference between a power supply and signals is avoided.
Description
Technical field
The utility model relates to the test fixture that a kind of lightning interface changes the USB converter, belongs 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.For convenience the user is connected with traditional USB interface, and Apple has also released lightning interface commentaries on classics USB converter, and this converter one end is USB interface, and the other end is the lightning interface.
Existing lightning interface changes the test of USB breakout box, is that testing tool uses USB plug directly to insert the USB end that the lightning interface changes the USB breakout box.Automated test device is used in modern production in a large number, because there is iron-clad in the USB plug periphery, the plastic housing outward appearance damage that often causes converter USB plug periphery in the measured object is inserted in robotization.
The utility model content
Utility model purpose: the utility model proposes the test fixture that a kind of lightning interface changes 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, also may be 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 that the interface contact is good simultaneously again.
Therefore the technical solution adopted in the utility model is the test fixture that a kind of lightning interface changes 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 the pcb board between female mouthful of USB and the 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 further improvement of the utility model, 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 the 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 the described pcb board, be convenient to this test fixture is fixed on the testing apparatus.
Beneficial effect: the utility model is installed in testing apparatus and the lightning interface changes 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 the plastic housing of the USB plug of converter again.Signal wire between female mouthful of USB golden finger and the USB and the wiring of power lead lay respectively at the upper and lower surface of pcb board, have avoided power supply and interference between signals.
Description of drawings

Embodiment
Below in conjunction with the drawings and specific embodiments; further illustrate the utility model; should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model; after having read the utility model; those skilled in the art all fall within the application's claims institute restricted portion 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 domain of the present utility model.
Embodiment one
As shown in Figure 1, tested lightning interface changes the USB converter and is installed on the 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 the 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.Pcb board 1 narrower one side is provided with USB golden finger 2, and the width X on this narrow limit of side is 12mm.The another side of the pcb board 1 relative with USB golden finger 2 is provided with female mouthful 3 of USB, and female mouthful 3 upper surface that is installed in pcb board 1 of this USB, opening upwards and can link to each other with the USB cable.Female mouthful 3 of 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.Signalling contact is connected by the signal wire 6 that is positioned at pcb board 1 upper surface.Test fixture need be fixed on the testing tool, and under the driving of testing tool, USB golden finger 2 is inserted into the USB end that tested lightning interface changes the USB converter.For the fixing test anchor clamps, be provided with mounting hole 4 in the position of pcb board 1 close USB golden finger 2, also offered two breach 5 in these mounting hole 4 both sides, better fix the effect of this test fixture to make things convenient for testing tool.Female mouthful 3 of USB is fixed on the pcb board 1 by two fixed orifices 8 that are positioned at its both sides.
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.
