Problems solved by technology

[0003] However, in the development or testing stage, the direct plug-in connection mode of the board brings certain troubles to software and hardware debugging and troubleshooting
For example, in the case of power supply, when the board is plugged into the device, there are certain obstacles in the process of programming programs and firmware to the board, and troubleshooting signal tests related to the hardware, resulting in time-consuming development and testing speed. longer
Specifically, in the signal test, when testing the voltage of the board, the in-line connection makes it difficult to detect the voltage value of the board; when testing the signal of the board, it is difficult to operate the oscilloscope in a relatively small space of the probe so that it accurately positions the test point you want to test

Embodiment 1

[0033] It should be noted that, for the convenience of description, the first and second descriptors are used in the embodiment of the present invention. In this application, the adapter board and the connector are called first and second, which have different meaning. Specifically, the first and second will be crowned in front of the adapter board, which are only used to distinguish different adapter boards. For example, the first adapter board refers to an adapter board with gold fingers, and the second adapter board refers to a slot. The adapter board; and the first and second in front of the connector are only used to distinguish the corresponding relationship between the connector and the two adapter boards, specifically, the first connector is on the first adapter board, The second connector is on the second adapter board.

Abstract

The invention discloses a board card switching device. The board card switching device comprises a first switching board, a second switching board and an intermediate transmission unit, wherein the first switching board is provided with a golden finger matched with a board card and a first connector connected with a connecting line of the golden finger; the second switching board is provided witha slot matched with the golden finger and a second connector connected with a connecting line of the slot; the first connector is matched with the second connector and connected with the second connector through the intermediate transmission unit. The board card switching device can lead all signals of the golden finger end of the board card while realizing transmission of power supply signals anddata signals of a mainboard and the board card to facilitate testing. Therefore, the board card switching device has the characteristics of being simple in structure and easy to carry and disassemble, development and debugging are facilitated, and further, development, debugging and maintenance efficiency of the board card can be improved. The invention further discloses a testing system having the corresponding technical effects.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a board switching device and a testing system. Background technique [0002] A board card is a printed circuit board, referred to as a PCB board. It is produced with a ferrule, which can be inserted into the slot of the computer's main circuit board (main board) to control the operation of hardware, such as monitors, acquisition cards, and sound cards. , network card and other equipment, after installing the driver, the corresponding hardware functions can be realized, and after the board card fails, the damaged board card can be pulled out, and the normal board card can be reinserted, so that the computer can continue to work. [0003] However, in the development or testing stage, the in-line connection of boards brings certain troubles to software and hardware debugging and troubleshooting. For example, in the case of power supply, when the board is plugged into the device, t...
