[0004] However, if the tolerance of the female part to be tested is large or the pin is too short and thin or the uniformity is low, the reliability of the above-mentioned contact conduction test will be very poor, for example, the female connector swings when writing data. In the test, even if the written data is good without interruption, it cannot guarantee that all pins are in good contact during the shaking process. It can be seen that the above-mentioned judgment method is unreliable in actual operation

The invention relates to a reliability testing apparatus for a computer external interface. The reliability testing apparatus is applied to testing of contact conduction of a female joint. A plurality of pins are arranged at one end of the female joint; and a plurality of insertion slots are arranged at the other end. The testing apparatus comprises a male joint, a second connector, a display unit, and a power supply unit. To be specific, one end of the male joint is provided with a plurality of contact pins matching the insertion slots; and the other end of the male joint is connected with a first connector. One end of the second connector is connected with the first connector; and the other end of the second connector is provided with lots of pins. One end of the display unit is connected with one pin of the second connector. One end of the power supply unit is connected with the other end of the display unit; the other end of the power supply unit is connected with another pin adjacent to one pin of the second connector; and the power supply unit is used for providing power for the display unit. With the testing apparatus, the accurate testing result can be obtained rapidly; and thus a problem that the existing female joint contact conduction testing of the computer external interface is not reliable can be solved.
Description
【Technical field】 [0001] The invention relates to a reliability testing device, in particular to a reliability testing device for an external interface of a computer. 【Background technique】 [0002] With the development of science and technology, computers are more and more widely used in daily life, so people's requirements for the quality of computers are getting higher and higher. [0003] Generally, when part engineering is approved, it is difficult to test the reliability of the external interface of the computer, such as the existing high-definition interface, video interface, 1394 interface or USB interface, etc. The existing test method is to use the external interface The female head of the machine is welded to the position of the female head of the high-definition interface, video interface, 1394 interface or USB interface that is compatible with the motherboard of the machine, and then inserted into the male head that is compatible with each female head, and then ...
