Fig. 6 a, 6b disclose connecting of the electric switch according to an embodiment of the present utility model with 6c
Disjunction mechanism coordinates the schematic diagram performing normal ON disjunction with electromagnetic operating mechanism.Electromagnetic operating mechanism
203 are used for realizing normal ON disjunction.There is on electromagnetic operating mechanism 203 pressure that can swing up and down
Plate 231.First work surface 124 at alignment contact supporter 102 top, front end of pressing plate 231.?
On-state, pressing plate 231 is rocked to top, and the front end of pressing plate 231 does not connects with the first work surface 124
Touch.Contact supporter 102 does not moves down.The effect of reaction spring 204 makes contact bridge 104
Contact contacts with the static contact of end of incoming cables 205 and leading-out terminal 206, end of incoming cables 205 and leading-out terminal 206
Keep electrical connection.Pressing plate 231 is rocked to lower section, the front end of pressing plate 231 and the first work surface 124
Contact, pressing plate 231 acts on the first work surface 124 and is pressed downward against by contact supporter 102, and contact props up
Gripping member 102 moves down, and drives contact bridge 104 and slide block 105 to overcome the spring of reaction spring 204
Power moves down, and the static contact of the contact on contact bridge 104 and end of incoming cables 205 and leading-out terminal 206 divides
From, the electrical connection of end of incoming cables 205 and leading-out terminal 206 disconnects.
Fig. 7 discloses connection disjunction mechanism and the operation of the electric switch of an embodiment of the present utility model
Mechanism coordinates the schematic diagram of the fault disjunction performed in addition to short circuit.Operating mechanism 202 is for realizing except short
Fault disjunction outside road.Having action link rod 222 on operating mechanism 202, action link rod 222 is directed at
Second work surface 125 at contact supporter 202 top.When not having fault to occur, operating mechanism 202
Being failure to actuate, action link rod 222 is left in place.When there is the fault in addition to short circuit, operating mechanism 202
Threading off, action link rod 222 moves down, downwardly against the second work surface 125 of contact supporter 102,
Contact supporter 102 moves down, and drives contact bridge 104 and slide block 105 to overcome reaction spring 204
Spring force move down, the contact on contact bridge 104 and end of incoming cables 205 and leading-out terminal 206 quiet
Contact separates, and the electrical connection of end of incoming cables 205 and leading-out terminal 206 disconnects.
When normal ON disjunction, generation fault in addition to short circuit carry out disjunction, for breaking speed
Less demanding.In connection disjunction mechanism the most of the present utility model, above two disjunction is supported by contact
Part 102 realizes, and contact supporter 102 can select density material high, good mechanical property to make,
And possess certain volume and thickness comes proof strength and stress-bearing capability, connect disjunction mechanism to improve
Overall mechanical life.Owing to above two disjunction is less demanding for breaking speed, therefore volume is relatively
Greatly, the contact supporter of heavier-weight can't affect piece electrical performance.
Fig. 8 discloses connection disjunction mechanism and the operation of the electric switch of an embodiment of the present utility model
Mechanism coordinates the schematic diagram performing short trouble disjunction.When short trouble occurs, due to short circuit current
Contact on contact bridge is directly scolded out by the electrodynamic repulsion force produced with static contact.Move there is no miscellaneous part
In the case of work, electrodynamic repulsion force is more than the spring force of reaction spring 204, and electrodynamic repulsion force can be by contact bridge
104 and slide block 105 be pressed downward against so that the electrical connection of end of incoming cables 205 and leading-out terminal 206 disconnects.
After contact bridge 104 moves down, drivening rod 103 moves downwardly together, the leg of pull bar 101
112 are connected to connecting rod 103, and therefore pull bar 101 moves downwardly together along with connecting rod 103.Pull bar 101
After Xiang Xia, coupler body 111 can contact with the lever 221 of operating mechanism 202, is pulled down by lever 221
Operating mechanism 202 is threaded off.After operating mechanism 202 is threaded off, action link rod 222 moves down, pressure
On the second work surface 125 of contact supporter 102, under the effect of action link rod 222, contact
Supporter 102 also moves down, and pushes down contact bridge 104 and slide block 105, prevents contact bridge 104 bullet
Return so that the electrical connection of end of incoming cables 205 and leading-out terminal 206 is stably disconnected, disjunction loop.
When occurring that short trouble needs to carry out disjunction, breaking speed is required, it is desirable to disjunction as early as possible.
Connection disjunction mechanism of the present utility model when performing short trouble disjunction, only contact bridge 104, sliding
Block 105, connecting rod 103 and these component actuation of pull bar 101, these piece volumes are little lightweight,
Can rapid action under electrodynamic repulsion force effect, quickly realize disjunction.After circuit disjunction, electrodynamic repulsion force
Disappear, in order to prevent reaction spring 204 from making slide block 105 and contact bridge 104 rebound and reclose back
Road, devises pull bar 101.Pull bar 101 can make operating mechanism 202 thread off by lever 221,
And then by action link rod 202, contact supporter is pressed for 102 times, push down contact bridge 104 and slide block
105 prevent resilience, it is ensured that the reliable disjunction in loop.
With continued reference to Fig. 8, in order to prevent pull bar 101 involuntary maneuver, pull bar when normal ON disjunction
Enough distances are left between 101 and lever 221.On the pressing plate 231 of electromagnetic operating mechanism 203
During lower swing, pull bar is less with the displacement of connecting rod, causes behaviour thus without touching lever 221
Make mechanical unlocking.When short trouble occurs, electrodynamic repulsion force contact bridge 104 can be scolded hold bigger away from
From, therefore pull bar 101 is followed connecting rod 103 and is moved bigger distance, touches lever 221 so that
Operating mechanism 202 is threaded off.
The connection disjunction mechanism of electric switch of the present utility model is for normal ON disjunction, non-shorting event
Barrier disjunction and short trouble disjunction are performed by different parts, have taken into account the mechanical strength of mechanism, use
Life-span and breaking speed, meet and reliable disjunction and the requirement of long service life.
Above-described embodiment is available to be familiar with person in the art and realizes or use this utility model
, those skilled in the art can in the case of without departing from utility model thought of the present utility model,
Above-described embodiment is made various modifications or change, thus protection domain of the present utility model is not gone up
State embodiment to be limited, and should be the maximum magnitude meeting the inventive features that claims are mentioned.
