In figure, state A is double points of location status, two combined floodgate levers sub-gate position (i.e. combined floodgate lever lifts), The free end of the upper connecting rod 205 of the left and right sides is (at the middle pin joint place of pin rod 2051 upper in scheming to be Represent) by the pulling force of energy-stored spring 206, it is lifted up around 2025, also symmetry on forward and backward cheek Connecting rod upper limit (2011,2011 ', 2021,2021 ' such as Figure 11 on being provided with on relevant position Indication), make connecting rod stable in the position of upper connecting rod upper limit respectively, then by two lower links, makeSpindle drum wheel 203Stable in by-level position, thus the double point position, centre realizing whole mechanism.

In figure, state B is main conjunction state, being converted to of state A-state B: when the combined floodgate lever in left side 207, when being moved to closing position by external force from double points of positions (right side is maintained at double point position), can stride across energy storage The dead-centre position (position on the line of i.e. 2025 and 2013) of spring 206, the upper connecting rod 205 in left side Free end can energy-stored spring 206 release can pulling force under, move downward around 2025 from connecting rod upper limit, For maintaining and spacing, on forward and backward cheek, also symmetry is provided with connecting rod lower limit (such as figure on relevant position 2012,2012 ', 2022, the 2022 ' indications of 11), i.e. go up connecting rod and at most can be moved under connecting rod Spacing position.And drive lower link and spindle drum wheel 203 to rotate to an angle counterclockwise simultaneously.Finally, Middle pin joint between lower link and the upper connecting rod in left side in left side can be crossed dead-centre position and form rigid support Structure.During this, owing to the long pinhole 2042 of lower link provides activity surplus, the combined floodgate on right side Lever 207 ' is not the most by External Force Acting, and therefore upper connecting rod and the combined floodgate lever on right side can remain stationary as. Main shaft 5 then rotates to an angle under the drive of spindle drum wheel 203 counterclockwise, drives composite contact mechanism 6 actions, connect main power source.

In figure, state C is standby conjunction state, if be in state B, switches over to state C, middle Need through state A, i.e. need to lift the former combined floodgate lever depressed, release the connection with former power supply, Side can connect another power supply.Equally, when being in state C, switch over to state B, it is also desirable to warp Cross state A.As a example by by state B to state C:

State B-state the A: (right side when the combined floodgate lever in left side is moved to double points of positions by external force from closing position Side be maintained at double point position), drive energy-stored spring energy storage, then the upper connecting rod 205 in left side is understood in energy storage Spring 206 is released after crossing dead point under the pulling force of energy, returns to connecting rod upper limit from connecting rod lower limit；And with Time drive lower link and spindle drum to take turns 203 dextrorotations and rotate back into level, i.e. return to double point position (shape State A), and under the upper connecting rod and energy-stored spring with right side acts on jointly, keep the equilibrium-like of horizontal level State.During this, upper connecting rod and the combined floodgate lever on right side remain stationary as.Spindle drum wheel 203 drive main shaft 5, main shaft 5 drives composite contact mechanism 6 action, is in double point state.

State A-state C: identical with the transfer principle of aforesaid state A-state B, the combined floodgate thick stick on right side Bar is moved to closing position (left side is maintained at double point position), drive energy-stored spring storage from double points of positions by external force Can, when energy-stored spring discharges, the upper connecting rod on right side can be under energy-stored spring releases the pulling force of energy, from connecting rod Upper limit moves to connecting rod lower limit.And drive lower link and spindle drum wheel 203 to turn clockwise one simultaneously Determine angle.Finally, lower link crosses dead point formation rigidity supporting structure with the upper connecting rod on right side.During this, Upper connecting rod and the combined floodgate lever in left side remain stationary as.Equally, spindle drum wheel 203 drive main shaft 5, main shaft 5 drive composite contact mechanism 6 action, connect stand-by power supply.

The energy storage linkage assembly of above-mentioned operating mechanism both can the most manually lift, depress conjunction The mode of brake lever rod, realizes the conversion of three kinds of states, it is also possible to by installing such as Fig. 3 extremely above it Manual-operating mechanism 1 shown in Fig. 9, by turn handle 101, drive a certain driven pulley (106 or 107) rotate, the poke rod (1061 or 1071) below this driven pulley the combined floodgate lever stretched into it Poke hole (2075 are referred to) coordinate, thus drive corresponding combined floodgate lever to lift or depress, it is achieved The conversion of three kinds of states.

It addition, present invention also offers the scheme realizing three kinds of State Transferring by the way of Electronic control, I.e. additionally provide the Electronic control assembly of operating mechanism, as shown in Figure 16 to Figure 21, described Electronic control Assembly includes: main conjunction electro-magnet switch 210, standby conjunction electro-magnet switch 210 ', double points of electro-magnet switch 211, main conjunction connecting rod 2102, standby close connecting rod, double points of connecting rods 2112, double sub lever 212 and double points of pull bars 213；

Described each electro-magnet switch is when powering up, and its iron core bounces back, and resets after power-off；

Main conjunction electro-magnet switch 210 and the standby iron core closing electro-magnet switch 210 ' pass through even upward and respectively Fishplate bar part is fixed between forward and backward cheek, and is each located on the side-lower of one group of connecting rod energy-storage units, Could also say that the side-lower being each located on a combined floodgate lever (207,207 '), mainly electric magnet Iron core retraction when switch powers up, for pressing offer power under respective combined floodgate lever.Implementing structure is: Main conjunction electro-magnet switch 210 and the standby iron core corresponding hinged main conjunction connecting rod respectively closing electro-magnet switch 210 ' 2102, standby respective one end closing connecting rod 2102 ', main conjunction connecting rod 2102, standby closes the another of connecting rod 2102 ' One end be respectively provided with a length direction point to connecting rod and iron core hinged place racetrack elongated hole (21021, 21021 '), the combined floodgate lever spring pin rod 208 hinged with energy-stored spring is inserted in elongated hole, and can be Along elongated hole length direction relative movement in elongated hole；

Double points of electro-magnet switch 211 are then the iron core front being fixed on front cheek 201 towards following formula, its ferrum Core 2111 is hinged with one end of double points of connecting rods 2112, the other end of double points of connecting rods 2112 and double sub levers One end of 212 is hinged；

A described double point pull bar 213 includes base plate 2131, and the forward and backward side of base plate 2131 is prolonged the most vertically upward Stretching and have a riser (2132), the both sides in the middle part of base plate 2131 have respectively downwardly extended an articulated slab 21311, The racetrack hinge hole 21312 that a length direction is parallel with base plate is had on each articulated slab 21311,；

It is positioned at below main shaft 5 on forward and backward cheek (201,202) and is respectively provided with a lifting apertures, described double The base plate 2131 dividing pull bar 213 is each passed through the lifting apertures of forward and backward cheek, and forward and backward cheek (201,202) before and after double points of pull bars 213 between the riser 2132 of both sides, riser 2132 Middle part has the elongated hole 21321 passed through for main shaft 5, and the length direction of elongated hole 21321 divides pull bars with double Lifting direction parallel, for double points of pull bars when lifting, it is to avoid touch with main shaft；Forward and backward cheek is positioned at A lead 2016 also it is respectively provided with, before and after double points of pull bars 213 on the riser 2132 of both sides above main shaft Have the gathering sill 21323 matched with lead 2016；

The middle part of double sub levers 212 is articulated with the front cheek 201 below main shaft 5 by jointed shaft 2121 The bottom of lifting apertures, and be positioned at the lower section of base plate 2131, the other end of double sub levers 212 passes through One jointed shaft is through the hinge hole 21312 of double points of pull bar 213 base plates, and this jointed shaft can be at hinge hole Length directions along hinge hole move that (this structure makes double points of pull bars 213 by double sub levers 212 in 21312 Drive under when doing lifting moving, lift path will not produce the skew of forward and backward)；Previously described mistake Another freedom in the same direction of the two lever sheets (2071,2072) of each combined floodgate lever (207,207 ') A pin 2076 respectively it is fixed with, both sides before and after double points of pull bars 213 on the pellet surface outwardly of end It is protruding that each outside to left and right, cant board 2132 top is convexly equipped with a hook corresponding with pin 2076 21322, when double points of pull bars 213 are pulled and move downward, hook projection 21322 catches on pin 2076, Two combined floodgate levers are driven all to lift.

Shown in Figure 16 to Figure 21 and Figure 22, introduce the Electronic control assembly of operating mechanism It it is the conversion how realizing three kinds of states by the way of Electronic control.

Double points of states: the iron core of each electro-magnet switch is in release conditions.Main shaft 5 is taken turns at spindle drum Under the effect of 203 and both sides lower link-upper connecting rod-energy-stored spring, balance is in horizontal level (double points of positions).

Main conjunction or standby conjunction state are to the switching (combined floodgate-> separating brake) of double points of states: when being in arbitrary closing position Time, double points of electro-magnet switch power up (another two electro-magnet switch is not powered), double points of electro-magnet switch Iron core adhesive bounces back, by double points of connecting rods 2112 pull double sub lever 212 in the middle part of it with front cheek Hinged support (jointed shaft 2121) rotates, thus drives a double point pull bar 213 to move downward.The most double points The hook projection 21322 of pull bar 213 can catch on the pin 2076 of combined floodgate lever and move downward, and makes combined floodgate Lever moves to sub-gate position from closing position, simultaneously combined floodgate lever dialling by poke hole 2075 and driven pulley The cooperation of lever, drives driven pulley to rotate thus drives rotatable handle to arrive double point position, and store up to energy-stored spring Energy.Then energy-stored spring release, pulls connecting rod to move to connecting rod upper limit from connecting rod lower limit.Then On another side under the counteracting force of connecting rod and energy-stored spring, stable in level.Complete from either side The process of combined floodgate-bis-separating brakes.

Double points of states A are to main conjunction or the switching (separating brake-> combined floodgate) of standby conjunction state (B or C): double points Electro-magnet switch is not powered, and main conjunction or the standby electro-magnet switch that closes power up, and corresponding iron core adhesive bounces back, and draws The combined floodgate lever of dynamic corresponding side moves to closing position from double points of positions, and combined floodgate lever stirs handle from double points simultaneously Indicating bit rotates to combined floodgate indicating bit, drives energy-stored spring energy storage simultaneously.Subsequently, energy-stored spring discharges, The upper connecting rod pulling corresponding side moves to connecting rod lower limit from connecting rod upper limit.And drive lower link and main shaft Seat wheel 203 is counterclockwise or the certain angle that turns clockwise.Main shaft revolves from horizontal direction with spindle drum wheel 203 Go to closing position, and finally stable on closing position.Now, between lower link and the upper connecting rod of corresponding side Understand dead point and form rigidity supporting structure.In the process, upper connecting rod and the combined floodgate lever of opposite side can be protected Hold motionless.Mechanism completes to assign to main conjunction or the standby electronic action conversion closed a floodgate from double.

It should be noted that after double electronic actions assigning to main conjunction or standby combined floodgate convert, main conjunction Or even if the standby electro-magnet switch that closes no longer powers up, i.e. corresponding iron core is upspring, due to the connecting rod that it is hinged The racetrack elongated hole (21021,21021 ') of the other end of 2102 exists, the combined floodgate lever being pressed down Will not lift because of the rising of the 2102 of connecting rod.

It addition, according to the requirement of GB14048.1, low-tension switch electric appliance equipment can not be used after contact melting welding The open position of any of which instruction electrical equipment, the combined floodgate lever of the side of aforesaid operations mechanism is in conjunction During lock state, if contact melts weldering, although main shaft and spindle drum wheel 203 can not rotate because contact melts weldering, But pressed down the combined floodgate lever of opposite side by external force, the combined floodgate lever of this side may be pressed under being forced and be turned Move to sub-gate position and be maintained at sub-gate position, demonstrating the separating brake index of mistake.Therefore, the present invention also provides for A kind of corrective measure, prevents contact from melting postwelding maloperation and instruction:

As shown in Figure 23 to Figure 25, main shaft 5 stretch out forward and backward cheek and be positioned at two combined floodgate levers The same side lever sheet (2071 and 2071 ', 2072 and 2072 ') between and be in same therewith Fixed cover is also distinguished equipped with an eccentric banking stop 214 in the position of plane, the end of each lever sheet towards Eccentric banking stop correspondence is convexly equipped with stopper section (in figure shown in 2076,2076 '), and eccentric banking stop 214 when rotating with main shaft 5, and the stopper section of the combined floodgate lever that eccentric banking stop can avoid combined floodgate side wraps The upset route of lock pin joint (as a example by 2013), is barred from again the stopper section of opposite side combined floodgate lever simultaneously Upset route.

As it can be seen, after adding eccentric banking stop 214 and stopper section, during double points of states, eccentric banking stop 214 are horizontal, and do not interfere with the feed motion of both sides combined floodgate lever.

After either side closes a floodgate, eccentric banking stop can rotate with main shaft, due to the setting of eccentrical shape, rotation After Zhuaning, one of them is placed exactly in eccentric position, 214 liang of right angles of limiting plate (can also be other shapes) On the upset route of opposite side stopper section, limited (the D indication as in Figure 24) by both counter stopper, The combined floodgate lever being in gate-dividing state can not carry out feed motion, thus prevents faulty operation from arriving combined floodgate, Also will not therefore show the combined floodgate instruction of mistake simultaneously.

The present invention is the most on the basis of the above, it is provided that another improves, and is directed to energy-stored spring and installs not Just problem:

As shown in Figure 10 and Figure 11 in energy-storage units structure, the installation method to energy-stored spring, it is common that Need by instrument by spring by force be pulled through assembling position, then pull-out connecting plate 2073 on through hole While put on spring pin rod (208,208 ') fix.If fix two (or above quantity simultaneously ) spring time, assembling can be more difficult.Meanwhile, the connecting plate 2073 by combined floodgate lever passes the chi in hole Very little and space limits, and frock clamp the most often cannot use.It addition, because being energy-stored spring, rigidity is relatively Greatly, need to fix many springs will be more difficult simultaneously.Many people compounding practice simultaneously is even needed just may be used To complete.

A thinking for the improvement of this problem is: make energy-stored spring pacify under uncharged free state Dress, based on this thinking, we change the position limiting structure form of the involutory brake lever rod of forward and backward cheek, it may be assumed that as Shown in Figure 23, Figure 24 and Figure 26, forward and backward cheek top between two combined floodgate levers is provided with one can The limited block 215 of dismounting, when not installing this limited block 215, combined floodgate lever rotates to touching cheek top During portion, energy-stored spring is in no load state, and after installing this limited block 215 additional, limited block 215 exceeds cheek When the top of plate and its width meet the sidewall that combined floodgate lever rotates to touching limited block 215, its energy storage bullet Spring is in load stress.

As shown in figure 27, now less due to the width in cheek top 20201 own, combined floodgate lever rotates To when touching top, energy-stored spring is the most unstressed, can the most individually wear spring pin rod (208,208 ') Fixing；Then, as shown in figure 28, by frock, combined floodgate lever is strutted to both sides, put into limited block 215 And it is fixed on cheek top；As shown in figure 29, after adding limited block 215, the energy storage of two combined floodgate levers Spring is maintained under the most first dress power.

The feature of this structure:

Install laborsaving, simply, improve production efficiency.Energy-stored spring due to be under no load state install, Can many, the most separately installed.

As shown in figure 30, position feedback component includes support body 40, and is installed on the shaft seat in support body 40 41, double points of position microswitch 422, main conjunction position microswitch 421 and standby close position microswitch 422, turns Axle bed 41 is socketed with main shaft by the main shaft trepanning 411 having on it, and can be with main axis, rotating shaft Seat 41 peripheries are provided with projection, double points of position microswitch 422, main conjunction position microswitch 421 and standby to close position micro- Dynamic switch 422 lays respectively at top and two sides of shaft seat, convex with shaft seat during main axis 41 Play the contact of each microswitch of conflicting respectively, trigger corresponding microswitch, to show corresponding state.

Contact mechanism is the mechanism being directly connected with power supply in transfer switching equipment, touching in contact mechanism Head by situation about whether moving be divided into moving contact and stationary contact first two, finger-type can be divided into again to clap by combination Box-like and blade type plug-in type two class, finger-type clapper-type contact when Guan Bi or disconnecting circuit at arcing under Can resist and burn, there is higher connection and breaking capacity, but owing to the node electric power of this type of contact is for scolding Power type, dynamic, the poor heat stability of contact, can scold under higher KA Rms effect and hold, therefore It is difficult to reach the requirement of the tolerance in short-term of standard regulation.The node electric power of blade type plug-in type contact is Attractive, it is dynamic, heat stability is high, can reach higher tolerance index in short-term, but due to this type of contact Using contactless design, therefore when Guan Bi or disconnecting circuit, this type of contact can not burn by arc resistant, it is difficult to Reach the requirement of higher connection and breaking capacity.Patent No. CN200710059760X discloses a kind of automatic The contact unit of transfer switching equipment, in moving contact group, existing finger-type clapper-type moving contact has again blade type to insert Formula moving contact, static contact group is then equipped with corresponding two finger-type clapper-type static contacts and two blade type are inserted Formula static contact, the advantage that both make use of two class contacts, the most effectively evade deficiency.But touching of this kind of structure Head unit also has deficiency: 1, blade type plug-in type static contact is provided with two, and structure is complex, increases Cost and fault may probabilities；2, moving contact group both sides lay two blade type plug-in type static contacts respectively With two finger-type clapper-type static contacts, and between blade type plug-in type static contact and finger-type clapper-type static contact There is provision of spring and support, therefore, the effective rotation angle range leaving moving contact for is subject to bigger restriction, It is only capable of reaching the angular range of maximum 90 degree, is additionally provided with double outside being not suitable for needing main conjunction, standby conjunction Divide state of switch electrical equipment.

Therefore, present invention also offers a kind of contact mechanism, to adapt to realize three kinds of state of switch electrical equipment Requirement.Scheme is as follows: as shown in figure 31,

Described contact mechanism includes the multiple contact units arranged successively side by side；

Each contact unit includes shell 61 and the moving contact group 62 being placed in shell 61, static contact Group and two arc-chutes 64；

Respectively have for (i.e. switching electricity through main shaft 5 on shell 61 and on the central part of moving contact group 62 For the main shaft of power transmission in device) by hole (as in figure, 611,621 are respectively shown in) and dynamic Sets of contacts is set on main shaft 5 by hole 621 and can be with main shaft 5 in shell 61 by thereon Rotate and rotate；

The both sides of the central part of described moving contact group are respectively to flex outward by specular centered by hole 621 Going out a moving contact plate portion 624, the moving contact plate portion of both sides conducts to each other, each moving contact plate portion 624 The blade type insertion of a most fixed clapper-type contact 622 and an arc is distinguished in the both sides being additionally included in its outer end Formula contact 623, and each blade type plug-in type contact 623 arc trend be with moving contact plate Bu Rao center Portion is the center of circle by hole 621；Owing to being specular, so the cutter in two moving contact plate portions 624 Type plug-in type contact 623 is towards identical direction, and respective clapper-type contact 622 is also both facing to another phase Same direction.

Static contact group includes laying respectively at two finger-type clapper-type stationary contacts that moving contact group switching centre portion two is lateral Head (631,632) and a blade type plug-in type static contact 633；Being used for of blade type plug-in type static contact 633 The junction surface 6331 engaged with blade type plug-in type contact 623 is correspondingly arranged at blade type plug-in type contact 623 On mobile route, two the respective contact of finger-type clapper-type static contacts (631,632) (6311,6321) In the opposite direction and the respectively clapper-type contact in a corresponding moving contact plate portion.

Two arc-chutes 64 lay respectively at two finger-type clapper-type static contacts (631,632) respectively with cutter In space between type plug-in type static contact 633, and respectively close to corresponding finger-type clapper-type static contact (631、632)。

Under double points of states as shown in figure 32, now moving contact group 62 is disposed vertically in shell 61, And do not contact with each static contact (631,632,633), it is impossible to build any one loop, touch Head mechanism is in double point state.

Main conjunction state as shown in figure 33, moving contact group 62 is prolonged and is rotated clockwise, to moving contact group The clapper-type contact 622 in the moving contact plate portion 624 of 62 one end is quiet with static contact group finger-type clapper-type Stop when the contact 6311 of contact 631 contacts, the now moving contact plate portion 624 of moving contact group 7 other end Blade type plug-in type contact 623 insert blade type plug-in type contact 623 junction surface 6331 in and be bonded with each other, 631, moving contact group 62 and 633 is built into a loop, and contact mechanism is in main conjunction state.

Standby conjunction state as shown in figure 34, moving contact group 62 prolongs counterclockwise rotation, to moving contact group The clapper-type contact 622 in the moving contact plate portion 624 of 62 other ends is clapped with another finger-type of static contact group and is closed Stop when the contact 6321 of formula static contact 632 contacts, the now moving contact plate portion of moving contact group 7 one end Blade type plug-in type contact 623 insert blade type plug-in type contact 623 junction surface 6331 in and be bonded with each other, 632, moving contact group 62 and 633 is built into another loop, and contact mechanism is in standby conjunction state.

It can be seen that no matter moving contact group is to rotate clockwise or counterclockwise, when closing, It is all that the clapper-type contact 622 of moving contact group first departs from electrical connection, departs from after blade type plug-in type contact 623, When engaging, it is all that the blade type plug-in type contact 623 of moving contact group first engages with static contact group, dynamic tactile Engaging with the finger-type clapper-type static contact of static contact group behind the clapper-type contact 622 of head group, this structure can have Effect reduces the node electric power that the box-like structure of doublebeat is brought, thus the operating physical force reducing main operation mechanism is wanted Ask；And during Guan Bi, plug-in type contacts one end and contacts one end Guan Bi prior to clapper-type, thus Realize non-loaded Guan Bi, effectively reduce contact electrical wear in closing course.In like manner, break in system During opening, plug-in type contacts one end and lags behind clapper-type and contact one end and disconnect, thus realizes non-loaded disconnected Open, it is possible to effectively reduce contact electrical wear during disconnecting.It addition, two finger-type clapper-types are quiet Contact (631,632) and a blade type plug-in type static contact 633 lay respectively at the two of moving contact group switching centre portion Side, makes the anglec of rotation of moving contact group more expand, and close to 180 degree, is more suitable for main conjunction, standby The device for switching of three kinds of State Transferring of double point state it is additionally provided with outside conjunction.

It addition, contact mechanism by closure state in off-state transformation process, moving contact group 62 need Prolong inverse or be rotated clockwise, the clapper-type contact 622 in moving contact group 62 and the finger of static contact group Inevitably produce between the contact (6311 or 6321) of type clapper-type static contact (631 or 632) Raw electric arc, the striking direction of arc-chutes 64 can be ejected on the inwall of shell 61, and therefore, the present invention is also The baffle plate 65 of irony is added, outside electric arc can be avoided to be directly injected between arc-chutes and shell 61 inwall On the inwall of shell 61, further, the length direction of baffle plate 65 is also correspondingly arranged on length direction with Its vertical screen cloth 66, baffle plate 65 also has the effect of guiding to electric arc, makes electric arc move to screen cloth 66.

Further, since in the processing of part and the clapper-type contact 622 of moving contact group and static contact group The contact of finger-type clapper-type static contact (631 or 632) can inevitably occur one in welding process A little errors, add caused error etc., various errors if main shaft and moving contact group are only rigidly connected Arise that after Lei Ji that the clapper-type contact 622 of moving contact is tired out due to above-mentioned with during the contact of static contact Point cantact phenomenon rather than optimal face that meter error causes contact, and therefore, the present invention is also to moving contact Group has done further improvement,

As shown in Figure 31 and Figure 35, Figure 36, Figure 37, moving contact group, including: central part is with dynamic Contact,

Described central part includes being docked by two circular forward and backward half shells (6212,6212 ') and being led to Cross bolt 6261 and nut 6262 and coordinate the central part housing of the formation being fixed together, central part housing Circumferential edge respectively have a moving contact plate portion by hole (enforcement as shown in figure 35 with casing center symmetry Example, each moving contact plate portion by Kong Ze be by by respectively have in each half shell half bore (62121, 62121 ') formed after docking), the center of central part housing has for (i.e. switching through main shaft 5 For the main shaft of power transmission in electrical equipment) and be set on main shaft by hole 621, and by hole 621 Size shape and main shaft cross-sectional sizes mating shapes, it is ensured that be affixed with main shaft 5 periphery by hole hole wall Closing, main shaft is directly by moving central part housing concomitant rotation by pore area.

Described moving contact includes:

Being clipped on the center connecting plate 625 of central part housing interior (between forward and backward half shell), center is even Fishplate bar 625 center have for main shaft 5 pass through hole 6251 (as shown in figure 36), and pass Space (i.e. main shaft 5 be not directed through this and drive through hole 6251 is left between hole 6251 and main shaft 5 Moving contact rotates)；

Also including, the both sides laying respectively at center connecting plate 625 are each moved tactile through the one of central part housing Head plate portion passes through outwardly directed moving contact plate portion, hole 624, and the moving contact plate portion of both sides is via in centre Heart connecting plate 625 realizes conducting to each other, and each moving contact plate portion 624 is additionally included in its outer end A most fixed clapper-type contact 622 and the blade type plug-in type contact 623 of an arc, and two are distinguished in both sides The clapper-type contact 622 in moving contact plate portion 624 is both facing to same direction.

Moving contact plate portion 624 and moving contact plate portion leave gap by between hole.

Owing to central part housing is directly socketed with main shaft by hole 621, (monolayer) moving contact is the most direct Being socketed with main shaft, the confession main shaft that is only intended to through hole 6251 of the center connecting plate 625 of moving contact passes , the center connecting plate 625 of moving contact is clipped between the forward and backward housing of central part housing, be i.e. by Central part housing drives moving contact to rotate, and the moving contact plate portion 624 of moving contact and central part housing Moving contact plate portion by having gap, therefore, when the clapper-type contact 622 of moving contact between hole When touching contact (6311 or 6321) of finger-type clapper-type static contact (631 or 632), moving contact Can be adjusted within the specific limits so that it is contact reaches preferable face with the contact of static contact and contacts.
