Embodiment
To be easy to understand the technical means, the inventive features, the objects and the advantages of the present invention, with reference to
Embodiment, the present invention is expanded on further.
Reference picture 1-8, present embodiment use following technical scheme：A kind of socket protective door protection structure, including
Panel 1, zero line block 2, live wire block 3, ground connection block 4, big stopper spring 5, the first small stopper spring 6, the second small block bullet
Spring 7 and power connection seat 8, zero line block 2, live wire block 3, ground connection block 4, big stopper spring 5, the first small stopper spring 6, second are small
Stopper spring 7 is arranged on the enclosure that panel 1 forms with power connection seat 8, and panel 1 is screwed with power connection seat 8, panel 1
On be provided with jack, be provided with block mounting groove on power connection seat 8, be grounded on block and inclined-plane chute is set, be grounded the left and right of block 4
Both ends are linked by latching with zero line block 2, live wire block 3, the front end of zero line block 2 and the first small stopper spring 6
One end is connected, and the front end of live wire block 3 is connected with one end of the second small stopper spring 7, is grounded the front end of block 4 and big block bullet
One end connection of spring 5, big stopper spring 5, the first small stopper spring 6, the other end of the second small stopper spring 7 are each attached to and connect
On electric seat 8, panel 1, zero line block 2, live wire block 3, ground connection block 4, big stopper spring 5, small stopper spring 6 and power connection seat 8
Constitute jack body, jack body and the grafting of plug 9.
Noticeable, described zero line block 2, live wire block 3, ground connection block 4 are in reset and original state
It is correspondingly arranged above three slot holes on power connection seat 2, when plug 1 is ready for insertion into, zero line block is driven by ground connection block 4
2nd, live wire block 3 moves, and opens pin hole, and convenient plug 1 continues into.
It is noticeable, it is provided with described power connection seat 8 and is available for zero line block 2, live wire block 3, ground connection block 4
The mounting groove of placement.
It is noticeable, one end of described zero line block 2, one end of live wire block 3 and it is fixed on power connection seat 8
Rotation axis connection, ground connection block 4 is stirred by the insertion of the ground terminal of plug 9, so as to drive zero line block 2, live wire block 3
Slide.
In addition, when plug inserts, described ground connection block 4 moves under group dynamic action of ground terminal to a direction
Dynamic, zero line block 2, live wire block 3 are under the motive force effect of the lock set by ground connection block 4, by design gradient movement；Zero
After ground connection block 4 is moved through certain position, the lock that block is set disengages for line block 2, live wire block 3, zero line block 2, fire
Line block 3 the first small stopper spring 6, the second small stopper spring 7 active force under reset, or with zero terminal, fire line terminal
Snug fit.
Present embodiment is when socket has conductive material insertion it may first have to which earthing pole is connected, and otherwise conductive electrode can not
Open, after conductive electrode is inserted, protective block can press close to conducting strip, prevent from being mistakenly inserted or draw electric arc to hurt sb.'s feelings；When plug is extracted, first
What is disconnected is conductive electrode, is grounded also in on-state, protective door device meeting quick closure conductive plug hole, is produced even if disconnecting
Electric arc can be also closed in protective block.
On the premise of ground terminal is not inserted into, when individually or simultaneously inserting zero fire line terminal, socket protective door can not be beaten
Open, electrode latch bore closure, electric current can not turn on, and cause to get an electric shock when effectively avoiding being mistakenly inserted.
Present embodiment is when being inserted separately into ground terminal, side of the ground connection stress of block 4 shown according to Fig. 4 arrows
To slip, driving zero line block 2, live wire block 3, zero line block 2, live wire block 3 go to Fig. 5 positions using mounting post as axis rotation
When putting, socket protective door is opened completely, and conductive body may be inserted into zero live wire pin hole, must now apply certain maintenance
Power, when otherwise continuing into, as shown in fig. 7, starting to thread off between block, zero line block 2, live wire block 3 are small first respectively
Stopper spring 6, the second small stopper spring 7 active force under start to reset, close pin hole；If do not continued to power, such as Fig. 8 institutes
Show, ground connection block 4 resets under the active force of big stopper spring 5, is threaded off between block, and zero line block 2, live wire block 3 are the
One small stopper spring 6, the second small stopper spring 7 active force under start to reset, close pin hole, this design actually using
In, effectively and reliably avoid object and be mistakenly inserted electric shock phenomenon caused by socket.
The operation principle of present embodiment：(1) such as Fig. 4, plug 9 insert, band when ground terminal stirs ground connection block 4
Dynamic zero line block 2 and live wire block 3 move to the direction of arrow, and by design requirement, ground pin insertion 3mm, ground connection block 4 can move
7mm is moved, now zero line block 2 and the firm jack of opening completely of live wire block 3, the zero terminal and fire line terminal on plug 9 are just
Insert slot hole；
(2) such as Fig. 5, plug 9 continues into, ground connection block 4 to the direction of arrow move to 8.5mm when, zero line block 2 and live wire
Block 3 is threaded off；
(3) zero line block 2 and live wire block 3 are respectively in the presence of the first small stopper spring 6, the second small stopper spring 7
Return, the terminal of zero line, live wire can be propped up, but do not influence the insertion of plug 9, plug 9 continues into, until the insertion of plug 9 is inserted
Seat, latch state such as Fig. 6；
(4) when plug 9 is extracted, electrode latch first departs from socket, and zero line block 2 and live wire block 3 first reset (such as Fig. 7),
Block 4 is grounded also in on-state, if any arc phenomenon is drawn, due to being grounded also in on-state, zero line block 2 and live wire
Block 3 has closed pin hole, and electric arc is enclosed in socket, avoids electric arc from hurting sb.'s feelings；
(5) such as Fig. 8, plug 9 continue to extract, and ground pin departs from ground connection block 4, and ground connection block 4 is in big stopper spring 5
Active force under reset, ground connection block 4 zero line block 2 and live wire block 3, zero line block 2 and fire can be hit during return
Line block 3 is hit that power influences can be 5 ° with rotary shaft swing, and zero line block 2 and live wire block 3 are still ensured that in 5 ° of swing and connect
In the reseting procedure of ground block 4, zero live wire latch is closed all the time.
(6) after being grounded the reset of block 4, zero line block 2 and live wire block 3 are respectively in the first small stopper spring 6, the second small gear
(such as Fig. 3) is equally being resetted according to rotary shaft under the active force of block spring 7.
Present embodiment is reasonable in design, and protective door can effectively prevent that being mistakenly inserted electric shock hurts sb.'s feelings, and security is good, can
High, effective arc extinguishing by property, prevent from altering outside electric arc and hurt sb.'s feelings, there is extensive market application foreground.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
