Embodiment 1

[0018] Such as figure 1 As shown, the tested lightning interface to USB converter is installed on the test instrument, mechanically connected with the test instrument, and the lightning interface of the converter is connected to other signal sources. The test instrument is connected to the USB female port 3 of the test fixture through a USB cable. The test fixture is fixed on the test instrument through the mounting hole 4 .

[0019] Such as Figure 2 to Figure 4 As shown, the PCB board 1 is rectangular, the width X of the PCB board is 12 mm, and the thickness Y is 2 mm. The narrow side of the PCB board 1 is provided with a USB gold finger 2, and the width X of the narrow side of the side is 12mm. The other side of the PCB 1 opposite to the USB golden finger 2 is provided with a USB female port 3, which is installed on the upper surface of the PCB 1 with an opening upward and can be connected with a USB cable. The power contacts of the USB female port 3 and the USB gold fi...

Embodiment 2

[0021] The width X of the PCB board is 11.9 mm, the thickness Y is 2.05 mm, and the other parts are the same as in the first embodiment.

Embodiment 3

[0023] The width X of the PCB board is 12.2 mm, the thickness Y is 2.1 mm, and the other parts are the same as in the first embodiment.

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 [0001] The invention relates to a test fixture for a lightning interface-to-USB converter, which belongs to the testing field. Background technique [0002] On September 12, 2012, Apple released a new Lightning Dock interface, translated into Chinese as lightning interface, for its new generation of iPhone5, iPod, and iPad products. In order to facilitate the user to connect with the traditional USB interface, Apple has also released a lightning interface to USB converter, which has a USB interface at one end and a lightning interface at the other end. [0003] The test of the existing lightning interface to USB adapter is that the test instrument uses a USB plug to directly insert the USB end of the lightning interface to USB adapter. Modern production uses a large number of automated testing equipment. Since there is an iron shell around the USB plug, automatic insertion into the object under test often causes damage to the appearance of the plastic shell ...
