Background technique

In recent years, the domestic electronics industry has been booming. In order to improve the reliability of electronic products, it is necessary to constantly think about better testing methods, so that electronic products have higher quality. However, servers and personal computers account for the bulk of the entire electronic product. In order to make the servers and personal computers more powerful, generally speaking, the main board has a plurality of expansion slots, so that users can plug in a few slots as they like. Functional adapter cards to enhance the functionality of servers and personal computers.

For example, the external device interconnection interface is used as a connection interface for expanding peripheral components in a computer system. Since the bus transmission speed of the PCI interface is faster than that of the traditional ISA interface, it has been widely used in the external expansion of the mainboard. interface. The specification of the PCI slot has 120 pins, among which power (PWR) and ground (GND) occupy 50 pins, and the remaining 70 pins are used for signal transmission. Since the PCI adapter card is an important peripheral equipment of the computer system, it is necessary to perform repeated signal tests on the host computer during the research and development or mass production stage to ensure its product quality.

Traditionally, an adapter card test system (such as a logic analyzer) used for computer testing needs to be directly connected to the computer motherboard in the computer case to capture signals on the PCI bus for analysis, which is not only inconvenient to operate but also time-consuming. Therefore, in the prior art, generally, a PCI riser card composed of connectors conforming to the PCI specification is provided with a row of wires welded at both ends, and one end of the PCI riser card leads a plurality of wires through the PCI riser card. And weld them to the corresponding gold fingers (as signal output terminals) on the PCI adapter card inserted in the PCI slot respectively, and the other end is a connection port that is electrically connected with the above-mentioned wires for example, so as to provide power supply Connect to a remote logic analyzer so that it can capture signals on the PCI bus for testing.

But above-mentioned prior art but implicitly contains many defectives: at first, because the connection of the PCI adapter card of PCI riser card and PCI slot is to adopt the mode of corresponding welding of wire, because of the pin position of PCI slot is numerous, so the The large number of wires required leads to a very complicated welding operation, and the software configuration of the function pins to be tested is required for each test. Repeated software configurations may also produce errors; what's more, in the prior art, only one set of test lines can be drawn from the PCI slot, that is, only one test device such as a logic analyzer can be provided during the test It is electrically connected to the PCI slot, but other test devices (such as Port 80/84 debug cards) are also electrically connected to the PCI slot at the same time, which severely limits its application and cannot make full use of each test device Perform a test of the PCI slot.

Therefore, how to provide a transfer device that can be electrically connected to multiple test devices at the same time, so as to overcome the drawbacks of the existing transfer design that can only provide one set of connection lines, which makes the test inconvenient and the effect is affected, has become a current problem. Problems to be solved.
