Description
Technical field
The present invention relates to a kind of mould, particularly a kind of adapter mould and relevant test method thereof of testing usefulness.
Background technology
Because the progress of electronic product technology, the transmission speed between computer system and the peripheral unit is more and more faster.And general serial connection bus (UniversalSerial Bus is hereinafter to be referred as USB) is most important interface between computer system and the peripheral unit.
The characteristics of USB maximum namely are to hold hot plug (Hot plug) and plug and play (Plug andplay).And the standard of USB is from early stage USB 1.1 to USB 2.0 to up-to-date USB 3.0, and its maximum characteristics namely are that transmission speed is more and more faster, and transmitting bandwidth is increasing.The characteristics of USB 3.0 maximums namely are that frequency range is enough large, and transmission speed is that 5Gbit/s is faster ten times than the transmission speed of USB 2.0 (480Mbit/s).
Please refer to Figure 1A and Figure 1B, its illustrate is USB 3.0A type connector (type A connector).USB 3.0A type connector comprises USB 3.0A type plug (the type A plug) 100 of Figure 1A and the USB 3.0A type socket (type A receptacle) 150 of Fig. 2 A.In general, as USB port, and 100 designs of USB 3.0A type plug are at assembly end (device terminal) on computer system in USB 3.0A type socket 150 design, for example Portable disk.
The USB 3.0A type socket 150 that the user can insert computer system with the 3.0A type plug 100 of assembly end can be reached signal and connect.Certainly, also can be at assembly end design USB 3.0A type socket 150, and the connecting line (cable) that utilizes two end points to be all USB 3.0A type plug 100 is reached computer system and is connected with signal between the assembly end.Certainly, also have the socket and plug of other type in the specification of USB 3.0, repeat no more.
Because USB 3.0 can be backward compatible to USB 2.0, therefore shown in Figure 1A and Figure 1B, comprise four USB 2.0 signal ends and five USB 3.0 signal ends in USB 3.0A type plug 100 and the socket 150.Wherein, USB 2.0 signal ends and USB 3.0 signal end amongs do not have dependence from independent.Moreover four USB 2.0 signal ends are Vbus, D+, D-, GND; Article five, USB 3.0 signal ends are USB3_RX, GND, USB3_TX.Wherein, Vbus is that bus voltage, D+ and D-are that differential wave is earth terminal to (differential pair), GND; USB3_RX be data receiver differential be that transfer of data is differential to (data transmitting differential pair) to (data receiving differential pair), USB3_RX.
In other words, if USB 2.0 assemblies insert the socket 150 of Figure 1B, then only having four USB2.0 signal ends can be in contact with one another, and computer system can be carried out transfer of data with USB 2.0 specifications; Otherwise if USB 3.0 assemblies insert the socket 150 of Figure 1B, then only having five USB 3.0 signal ends can be in contact with one another, and computer system can be carried out transfer of data with USB 3.0 specifications.
In general, computer system all can be equipped with a plurality of USB port, and computer system must be carried out the test of USB port before dispatching from the factory, to determine that USB can normal operation.Because in the computer system, the control circuit of USB 3.0 can be backward compatible to USB 2.0, so 3.0 ports of the USB in the computer system need segmentation to carry out USB 2.0 tests and USB 3.0 tests when testing.
That is, when carrying out USB 2.0 test, need and will carry out USB 2.0 tests in USB 2.0 equipment insertion computer system USB 3.0 ports; After finishing, manually pull out again USB 2.0 equipment and USB 3.0 equipment are inserted continuation test in computer system USB 3.0 ports.Certainly, USB 2.0 tests can be exchanged with the order of USB 3.0 tests.
According to actual test statistics, computer system is carried out test program (test program) with time in each about 10 second of test USB2.0 and test USB 3.0, add the time of plug equipment and operation computer system, USB 3.0 ports need about testing time more than 30 seconds.If computer system has four USB 3.0 ports, then testing a computer system need to surpass more than 2 minutes.
Therefore, how to carry out more efficiently the test of USB 3.0 ports, simplify the testing time, be the purpose that the present invention wants to reach.
