See also Fig. 4 A, it is the structural representation of connector shown in Figure 3.Shown in Fig. 4 A, the 3rd connector of transmission line 341 and 342 1 ends and first connector 312,313, and the structure between the 3rd connector of the transmission line 341 and 342 other ends and second connector 3291,3292 is set to the fixing that cooperatively interacts of form with male seat 41 and female seat 42.Kenel as for configuration can be according to the actual demand adjustment, for example: the 3rd connector of transmission line 341 and 342 1 ends can be male seat 41 design and first connector 312,313 can be female seat 42 designs, and the 3rd connector of the transmission line 341 and 342 other ends can be female seat 42 designs and second connector 3291,3292 can be male seat 41 designs.And no matter connector is that male seat 41 or female seat 42 designs all need and will contract in the charged part, pulls out transmission line 341 or can touch live terminal at 342 o'clock and meet accident to prevent the user.
In the present embodiment, transmission line 341 and 342 can be power transmission line (power cord), and male seat 41 shown in Fig. 4 A and female seat 42 have a plurality of first conductive structures and a plurality of second conductive structure respectively.Wherein, first conductive structure of male seat 41 can be the first metal clamping part 411, the one end is respectively applied for clamping power line 414, and second conductive structure to be length more described second short metal clamping part 412 of the first metal clamping part 411, the same holding wire 415 of one end clamping of described a plurality of second metal clamping parts 412 makes 412 of described a plurality of second metal clamping parts be connected to each other (shown in Fig. 4 C).
And described a plurality of first conductive structures of female seat 42 can be first conducting strip 423, the one end is respectively applied for clamping power line 424, and a plurality of second conductive structures can be second conducting strip 425, the same holding wire 426 of one end clamping of a plurality of second conducting strips 425 makes 425 of a plurality of second conducting strips be connected to each other (shown in Fig. 4 A and Fig. 4 C).
After male seat 41 and female seat 42 connections, first conducting strip 423 will be connected with the first metal clamping part 411, and second conducting strip 425 will be connected (shown in Fig. 4 B) with the second metal clamping part 412; Otherwise, when male seat 41 and female seat 42 breaks away from, will separate with the first metal clamping part 411 than first conducting strip 423 between second conducting strip 425 and the second metal clamping part 412 in advance.See also Fig. 4 C, it shows when the distance of separation between male seat 41 and the female seat 42 is L, has finished between second conducting strip 425 and the second metal clamping part 412 and has separated.
In order to prevent that the user from pulling out transmission line 341 or can touch live terminal at 342 o'clock and meet accident, first metal clamping part 411 of male seat 41 and first conducting strip 423 of the second metal clamping part 412 and female seat 42 and second conducting strip 425 all are arranged at enclosure interior, and for male seat 41 and female seat 42 can firmly be combined, have a plurality of ribs 413 on the male seat 41, female seat 42 then has guide rail 421 and guide groove 422 structures, when both are plugged on a time-out a plurality of ribs 413 are inserted in the corresponding guide rail 421 and guide groove 422, so that male seat 41 and female seat 42 firmly are plugged on together (shown in Fig. 4 B) respectively.
Please consult Fig. 3 again, a signal terminal is connected with resistor R 1 in second connector 3291 of first uninterruptible power supply provider 32, and another signal terminal then is connected with pull-down circuit 328.Therefore, when the 3rd connector at transmission line 341 two ends is plugged in second connector 3291 of first connector 312 of block terminal 31 and first uninterruptible power supply provider 32 respectively, first connector 312 of block terminal 31, transmission line 341 and the resistor R 1 that is connected with second connector 3291 and 328 of pull-down circuits will form a loop, and voltage source will transmit 5V voltage to resistor R 1.
The circuit structure and the connected mode of second connector 3292 of first connector 313, transmission line 342 and first uninterruptible power supply provider, 32 outputs that comprised as for block terminal 31 inputs, all second connector 3291 with above-mentioned first connector 312, transmission line 341 and first uninterruptible power supply provider, 32 inputs is identical, so do not repeat them here.
When the two ends of transmission line 341 and 342 all normally are plugged on the block terminal 31 and first uninterruptible power supply provider 32, will be via first connector 312 of block terminal 31, transmission line 341 and the resistor R 1 that is connected with second connector 3291 and 328 formed loops of pull-down circuit, transmit the voltage signal of 5V to pull-down circuit 328 by resistor R 1 end, and pull-down circuit 328 will transmit the voltage signal of 5V to controller 326, and controller 326 will judge that operating all at present normally keeps 32 normal operations of first uninterruptible power supply provider according to this voltage signal this moment.
Otherwise, when if the user pulls out an end of transmission line 341 or 342, owing to will separate with the first metal clamping part 411 than first conducting strip 423 between second conducting strip 425 of the described connector that the present invention uses and the second metal clamping part 412 in advance, therefore the second metal clamping part 412 of male seat 41 will break away from female seat 42 (shown in Fig. 4 C) earlier than the first metal clamping part 411, when in case the second metal clamping part 412 of male seat 41 breaks away from second conducting strip 425 of female seat 42, first connector 312 or 313 of block terminal 31, transmission line 341 or 342 and can't form a loop with second connector 3291 or 3292 resistor R that are connected 1 and 328 of pull-down circuits, make pull-down circuit 328 will transmit the voltage signal of 0V to controller 326, controller 326 will judge that described first uninterruptible power supply provider 32 takes place unusual according to this voltage signal (being the driving of triggering signal) this moment, and will produce control signal control AC/DC converter 321 and AC/DC converter 325 decommissions, first uninterruptible power supply provider 32 is decommissioned, make the output of block terminal 31 can not transmit electric current to the first uninterruptible power supply provider 32.Therefore, when the first metal clamping part 411 of male seat 41 breaks away from first conducting strip 423 of female seats 422, because no current and will can not produce arc discharge phenomenon (promptly producing spark), thereby can be safely first uninterruptible power supply provider 32 of fault be removed.
Hence one can see that, and for being arranged in parallel, therefore when wherein one when breaking down, load 22 can continue to provide voltage by an other uninterruptible power supply provider 32 or 33 between first uninterruptible power supply provider 32 and second uninterruptible power supply provider 33.And, can be safely the uninterruptible power supply provider 32 or 33 of fault be removed parallel system and repair so that send as long as the transmission line 341 or 342 that the uninterruptible power supply provider 32 or 33 of fault is connected to block terminal 31 removes.
As for, the block terminal 31 inner diverter switches 311 that are provided with are mainly used in to switch to when first uninterruptible power supply provider 32 and/or 33 normal operations of second uninterruptible power supply provider first uninterruptible power supply provider 32 and/or second uninterruptible power supply provider 33 are electrically connected with load 22 through connector 313, the required voltage of load 22 runnings to be provided and when power supply 21 generations are unusual, to continue power supply, to guarantee the normal operation of load 22; Otherwise, when if first uninterruptible power supply provider 32 and second uninterruptible power supply provider 33 all damage, switch module 311 will switch to bypass (Bypass) loop, even also power supply 21 directly is connected with load 22, directly provide to load 22 with the alternating current that power supply 21 is provided.Wherein, pull-down circuit 328 can be made up of resistor R 2 and electric capacity, but not as limit.
In addition, first uninterruptible power supply provider 32 and second uninterruptible power supply provider 33 include external communication ports 327 and 337 respectively, mainly come to transmit about the state of its internal circuit running and relevant data signals uninterruptible power supply provider to the other side for first uninterruptible power supply providers 32 and second uninterruptible power supply provider 33 by signal transmssion line 35, first uninterruptible power supply provider 32 and second uninterruptible power supply provider 33 can be linked up, with the required energy of equalization of incidence load 22 mutually; Perhaps, when any uninterruptible power supply provider can't operate, transmit signal by external communication ports 327 and 337 and make the another one uninterruptible power supply provider adjust the supply of its energy.
See also Fig. 5, it is for the structural representation of parallel non-interrupted power supply system second preferred embodiment of the present invention.As shown in Figure 5, parallel non-interrupted power supply system 50 is connected with power supply 21 and load 22 equally, and form by block terminal 51, first uninterruptible power supply provider 52, second uninterruptible power supply provider 53 and transmission line 54 and 55, and the inside built-up circuit of first uninterruptible power supply provider 52 and second uninterruptible power supply provider 53 is identical in fact.
Wherein, circuit framework, design principle and the purpose that can reach of AC/DC converter 521, charging circuit 522, battery 523, DC-DC converter 524, AC/DC converter 525, controller 526, external communication ports 527 and pull-down circuit 528 that first uninterruptible power supply provider, 52 inside comprise and effect all have been specified in first preferred embodiment introduction, so do not repeat them here.
In the present embodiment, block terminal 51 inside also comprise first connector 512 and 513 that is arranged at output and input respectively except diverter switch 511, and transmission line 54 and 55 two ends all have the 3rd connector.As for, first uninterruptible power supply provider 52 and second uninterruptible power supply provider 53 have one second connector 5211 and 5311 respectively, because the built-up circuit of first uninterruptible power supply provider 52 and second uninterruptible power supply provider 53 and all identical, only explanations are proposed below therefore with first uninterruptible power supply provider 52 with the annexation of block terminal 51 and transmission line 54,55.
