Detailed description of the invention

Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail, in attached drawing:

Fig. 1 is the electrical block diagram of the utility model embodiment.

Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.

As shown in Figure 1, PCIE SSD circuit breaking test device provided by the embodiment of the utility model, including relay, relay Device power supply module, relay driving module and the test computer 1 for being equipped with PCIE SSD, wherein the power supply of test computer 1 is defeated Enter end to be connected with one end switch S of relay, the switch S other end of relay is connected with relay power supply module, relay Drive module includes the switch element being connected with the coil J output end of relay and the controller 2 being connected with switch element, relay Device power supply module includes power supply side VCC, first diode D1 and first capacitor C1, the anode of first diode D1 simultaneously with Power supply side VCC is connected with the switch S other end of relay, the first end of first capacitor C1 simultaneously with first diode D1 Cathode be connected with the coil J input terminal of relay, the second end of first capacitor C1 ground connection.When specifically used, controller 2 It is powered and is powered off a period of time every set time control switch element, is divided into 3-10 seconds between power-off time as being powered every time, When switch element is powered, the coil J of relay is powered, and the switch S of relay is driven to be attracted.Power supply side VCC for after Passing through first diode D1 while the switch S power supply of electric appliance is first capacitor C1 charging, when first capacitor C1 both end voltage reaches It is the supplying power for input end of the coil J of relay after to the pick-up voltage of relay, after the switch S of relay is attracted, is equipped with The test computer 1 of PCIE SSD obtains electric carry out normal operating condition.When the input terminal voltage VCC of the switch S of relay drops suddenly When low, the characteristic that cannot be mutated using capacitor both end voltage still can maintain the pick-up voltage of relay, and at this time the 1st The cathode voltage of pole pipe D1 is lower than cathode voltage, first diode D1 cut-off, therefore first capacitor C1 is the coil J's of relay Supplying power for input end, the switch S of relay continues to keep attracting state, so as to avoid during the test, due to voltage instability Lead to the input terminal voltage of relay switch reduces suddenly, makes relay coil electricity shortage and causes relay switch power down Situation avoids the case where voltage instability causes test data to malfunction, and substantially increases the accuracy of test data.
