Description
Technical field
The present invention relates to a kind of test and use load device.
Background technology
PDU (power distribution unit, power distribution unit) device has been applied in the power management of server widely, and it has power distribution and management function.
The PDU device is researched and developed or during production test in the early stage; Need carry out burn in process; The concrete two parts that divide; First's test is on each power interface of PDU device, all to insert fixedly first load of power consumption simultaneously, and the magnitude of current that all first loads are extracted equals the maximum current output quantity of PDU device; The second portion test then is on each power interface of PDU device, to insert fixedly second load of power consumption respectively, and the magnitude of current that this second load is extracted equals the maximum current output quantity of PDU device.Only, this two-part test then need be prepared first load simultaneously and second load could realize if will accomplish, and so has the problem of cost waste.
Summary of the invention
In view of foregoing, be necessary to provide a kind of test to use load device, can realize multiple test request, to reach the purpose that reduces cost.
Load device is used in a kind of test; Comprise a main road attaching plug, some branch supply plugs, a main road power switch, some branch supply switches and some loads; This main road power switch and branch supply switch are single-pole double-throw switch (SPDT); First end of this main road attaching plug is connected to first throwing point of this main road power switch, and second throwing point of this main road power switch is vacant, and the cutter portion of this main road power switch is connected to second throwing point of this branch supply switch respectively; First throwing point of this branch supply switch is connected to first end of corresponding branch supply plug respectively; Second end of this branch supply plug all is connected to second end of this main road attaching plug, and the cutter portion of this branch supply switch is connected to first end of corresponding load respectively, and second end of this load all is connected to second end of this main road attaching plug.
Compare prior art; The present invention tests can be through the switching of this main road power switch and branch supply switch with load device; Optionally control load inserts electronic equipment to be measured; Thereby satisfy the multiple test request of this electronic equipment to be measured, owing to need not to prepare many group load devices, so can effectively reduce cost.
Description of drawings
Combine preferred embodiments that the present invention is described in further detail with reference to the accompanying drawings:
Fig. 1 tests the synoptic diagram with the load device preferred embodiments for the present invention.
Fig. 2 tests the circuit diagram with the load device preferred embodiments for the present invention.
The main element symbol description
Test is with load device 100
Housing 110
Main road attaching plug 10
Branch supply plug 20-90
Main road power switch 12
Branch supply switch 22-92
Load 220-920
Embodiment
Please refer to Fig. 1 and Fig. 2, the preferred embodiments that the present invention tests with load device 100 comprises a housing 110, and the shape of this housing 110 can be provided with arbitrarily, like rectangle.This test with load device 100 also comprise a main road attaching plug 10, some branch supply plug 20-90, one with the corresponding main road power switch of this main road attaching plug 10 12, some respectively with the corresponding branch supply switch of this branch supply plug 20-90 22-92, some load 220-920 of equating with this branch supply plug 20-90 quantity.This embodiment is that eight branch supply plugs, eight branch supply switches and eight loads illustrate with quantity, and above-mentioned quantity can increase or reduce according to actual test request is corresponding.
Wherein, this main road attaching plug 10, this branch supply plug 20-90, this main road power switch 12 and this branch supply switch 22-92 all are located at the outside of this housing 110, and this load 220-920 then is located at the inside of this housing 110.This main road power switch 12 and this branch supply switch 22-92 are single-pole double-throw switch (SPDT), include a cutter portion 1 and two throwing points 2,3, and when pressing single-pole double-throw switch (SPDT), its cutter portion 1 all switches on another throwing point from a throwing point at every turn.
First end of this main road attaching plug 10 is connected to the throwing point 2 of this main road power switch 12, and the throwing point 3 of this main road power switch 12 is vacant, and the cutter portion 1 of this main road power switch 12 is connected to the throwing point 3 of this branch supply switch 22-92 respectively.The throwing point 2 of this branch supply switch 22-92 is connected to first end of corresponding branch supply plug 20-90 respectively, and second end of this branch supply plug 20-90 all is connected to second end of this main road attaching plug 10.The cutter portion 1 of this branch supply switch 22-92 is connected to first end of corresponding load 220-920 respectively, and second end of this load 220-920 all is connected to second end of this main road attaching plug 10.
When this test of application is tested like a PDU device (not shown) with 100 pairs one electronic equipments of load device; If the test of the first of this PDU device is on each power interface of PDU device, all to insert a fixedly load of power consumption simultaneously; Then the cutter portion 1 with this branch supply switch 22-92 all switches on the throwing point 2, then this branch supply plug 20-90 is inserted respectively on the power interface of this PDU device and can carry out first's test to this PDU device.If the test of the second portion of this PDU device is on each power interface of PDU device, to insert the fixedly load of power consumption respectively; Then the cutter portion 1 with this branch supply switch 22-92 all switches on the throwing point 3; And the cutter portion 1 of this main road power switch 12 switched on the throwing point 2, then this main road attaching plug 10 is inserted respectively on the power interface of this PDU device and can carry out the second portion test to this PDU device.In this embodiment, the resistance value of this load 220-920 all equates and total resistance value satisfies the maximum current output quantity that the magnitude of current that is extracted equals the PDU device, and other embodiment can be chosen suitable resistance value according to the test needs.
Because the present invention tests with load device 100 and only uses the multiple test request that one group of load 220-920 can accomplish the PDU device, need not be respectively to the loads of the many groups of two parts test preparation, so provide cost savings.
