Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with detailed description of the invention, the present invention is expanded on further.
nullWith reference to Fig. 1-8，This detailed description of the invention is by the following technical solutions: socket protective door protection structure，Including panel 1、Power connection seat 2、Ground connection block 3、Zero line block 4、Live wire block 5、Big stopper spring 6 and little stopper spring 7，Panel 1 is provided with jack，Power connection seat 2 is provided with block mounting groove and block mounting post，Panel 1 and power connection seat 2 are screwed，Ground connection block 3 it is provided with between panel 1 and power connection seat 2、Zero line block 4、Live wire block 5、Big stopper spring 6、Little stopper spring 7，Ground connection block 3、Zero line block 4、Live wire block 5 is respectively provided with the bossed snap close with guiding，Ground connection block 3 is additionally provided with inclined-plane chute，Ground connection block 3 is connected with one end of big stopper spring 6，The other end of big stopper spring 6 is fixed on power connection seat 2，Zero line block 4、The outside of live wire block 5 is all connected with one end of little stopper spring 7，The other end of little stopper spring 7 is separately fixed at the two ends, left and right of power connection seat 2，Ground connection block 3 and zero line block 4、Live wire block 5 is linked each through snap close.
It should be noted that described panel 1, ground connection block 3, zero line block 4, live wire block 5, big stopper spring 6, little stopper spring 7 and power connection seat 2 constitute jack body, jack body and plug 8 grafting.
It should be noted that, described ground connection block 3, zero line block 4, live wire block 5 reset and during original state corresponding with three slot hole sites on power connection seat 2, when plug 8 inserts, ground connection block 3 drive zero line block 4, live wire block 5 to rotate, pin hole is opened, convenient insertion.
Additionally, described zero line block 4, live wire block 5 are rotatably installed on power connection seat 2, zero line block 4, live wire block 5, when reset and original state, can effectively isolate the object being individually mistakenly inserted zero firewire jack, it is to avoid get an electric shock；When plug 8 inserts, ground connection block 3 moves under dynamic action in dialling of ground terminal, and zero line block 4, live wire block 5 are under the snap close motive force effect set by ground connection block 3, with block mounting post for axis rotation；When zero line block 4, live wire block 5 are after ground connection block 3 is moved through certain position, the snap close that block is arranged disengages, zero line block 4, live wire block 5 under the active force of little stopper spring 7 with block mounting post position axis rotation reset, or with zero terminal, fire line terminal snug fit.
This detailed description of the invention is when socket has conducting objects to insert, it is necessary to first insert ground terminal, and otherwise socket protective door cannot be opened, it is prevented that conductive body is mistakenly inserted and causes getting an electric shock；When plug is extracted, what first disconnect is conductive electrode, and ground connection is also in on-state, and first little block resets under the action of the spring, simultaneously closes off electrode pin hole what conductive electrode disconnected, effectively prevents from drawing electric arc casualty accident.
This detailed description of the invention under the premise being not inserted into ground terminal, insert zero individually or simultaneously, fire line terminal time, socket protective door cannot be opened, and electrode pin hole is closed, and electric current cannot turn on, and causes getting an electric shock when effectively avoiding being mistakenly inserted.
It should be noted that, when being inserted separately into ground terminal, slide in ground connection block 3 stress direction shown in Fig. 4 arrow, drive zero line block 4, live wire block 5 is with mounting post position axis rotation, zero line block 4, when live wire block 5 goes to Fig. 5 position, socket protective door fully opens, conductive body may be inserted into zero live wire pin hole, now, certain maintenance energy must be applied, otherwise, when continuing into, as shown in Figure 7, zero line block 4, live wire block 5 starts to thread off, zero line block 4, live wire block 5 starts to reset under the active force of little stopper spring 7, close pin hole；If do not continued to power, as shown in Figure 8, ground connection block 3 resets under the active force of big stopper spring 6, zero line block 4, live wire block 5 are threaded off, zero line block 4, live wire block 5 start to reset under the active force of little stopper spring 7, closing pin hole, this design in actual use, effectively and reliably avoids object and is mistakenly inserted the electric shock phenomenon that socket causes.
The operation principle of this detailed description of the invention: (1) is such as Fig. 4, when plug 8 inserts, zero line block 4, live wire block 5 is driven to rotate when ground connection block 3 stirred by its ground terminal, ground connection block 3 moves 2.5mm to the direction of arrow, zero line block 4, live wire block 5 just rotate 20 °, at this moment protective door is opened, and the zero line of plug 8, fire line terminal are ready for insertion in electrode slot hole；
(2) such as Fig. 5, plug 8 continues into, ground connection block 3 continues the direction of arrow and moves, when movement has 5mm, zero line block 4, live wire block 5 have rotated into 26 °, three terminals of plug are completely in jack, zero line block 4, live wire block 5 start to thread off, at this moment ground connection block 3 cannot interfere zero line block 4, live wire block 5, zero line block 4, live wire block 5 utilize the power of the spring of side to rotate (about 8 degree) according to rotating shaft until and prop up zero, fire line terminal, but do not affect the insertion of plug；
(3) plug 8 fully-inserted (such as Fig. 6)；
(4) when plug 8 starts to extract, first zero line block 4, live wire block 5 reset (such as Fig. 7) under the action of the spring, until zero line block 4, live wire block 5 prop up limit rib, electrode hole is closed；Electrode pin hole is closed in time, effectively prevent and draws electric arc casualty accident, and ground connection block 3 also can start to reset simultaneously；
(5) plug 8 continues to extract, ground connection block 3 continues to reset, now ground connection block 3 and zero line block 4, snap close position between live wire block 5 has interference, zero line block 4, the limited muscle of live wire block 5 props up, ground connection block 3 extrudes zero line block 4 under the active force of big stopper spring 6, live wire block 5, the spring force of big stopper spring 6 is more than the spring force of the little stopper spring 7 in side, size block utilizes inclined-plane to stir, force zero line block 4, live wire block 5 can only move to both sides with elliptical aperture for axis, until getting out of the way the space that ground connection block 3 resets, in this process, zero firewire electrode pin hole is closed (such as Fig. 8) all the time；
(6) ground connection block 3 resets and puts in place, and zero line block 4, live wire block 5 are replied by little stopper spring 7 active force and put in place and prop up limit rib, return to original state (such as Fig. 3).
This detailed description of the invention reasonable in design, protective door can effectively prevent from being mistakenly inserted altering outside operation or electric arc and hurt sb.'s feelings, and reaches arc extinguishing purpose, and safety is good, and reliability is high, reduces the probability that peril occurs, has market application foreground widely.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; described in above-described embodiment and description is that principles of the invention is described; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within the claimed scope of the invention.Claimed scope is defined by appending claims and equivalent thereof.
