[08] described lock actuation mechanism---be called " formula that is rotationally connected mechanism ", satisfactory aspect the cut-out circuit function in the special applications of in relating to above-mentioned file, describing.
Summary of the invention
[09] however the object of the invention be described lock actuation mechanism is improved, and particularly improve to participate in the cooperation of the different component of described mechanism release.
[10] the present invention proposes the formula that is rotationally connected a lock actuation mechanism that is used for the automatic safe circuit breaker for this reason, and it comprises:
[11]-one frame;
[12]-one hinged handle, it is rotatably installed in goes up and has one with respect to fixing one of described frame and connect the end, and described hinged handle is allowed an interlocking position and a unlocked position, and is actuated to its unlocked position by a spring;
[13]-one intermediate bar, it is around installing rotationally with respect to fixing one of described frame, and is suitable for matching with the described end that is connected of described hinged handle;
[14]-one connecting rod, it connects the surface around installing, and have one rotationally by of described intermediate bar supporting, and described connections is surperficial to be suitable for matching with the end that is connected of described hinged handle;
[15]-one mechanical spring, it is actuated described connecting rod and rotates in a predetermined direction around its axle;
[16]-one contact device, it comprises at least one fixed contact and at least one corresponding movable contact, described device is allowed a primary importance and a second place: on described primary importance, described fixed contact and described movable contact are separated from each other out; On the described second place, described fixed contact and described movable contact touch each other against maintenance, enter the described second place from described primary importance and are controlled by described intermediate bar;
[17]-and holding device---it remains on described connecting rod on one settling position, and described holding device comprises a strut, and described connecting rod is suitable for can resting under the effect of described mechanical spring on the described strut;
[18]-one actuator, it allows a retrieving position and an extended position: on described retrieving position, it is with respect to described holding device indentation; On described extended position, it acts on the described holding device;
[19] described mechanism allows a contact position, on described contact position, hinged handle on its interlocking position is firmly supported to arrive in, so that actuating described connection end touches and leans against on the thrust block seat, described thrust block seat is formed with described intermediate bar jointly by the connection surface of the described connecting rod on its settling position, and therefore described hinged handle actuates described intermediate bar, so that contact device is remained on its second place;
[20] described mechanism is characterised in that, described intermediate bar has a stop surfaces; And when connecting rod is on its settling position, connect surface and stop surfaces and limit a convergence wall type groove seat, described groove seat forms described thrust block seat, the connection end of described hinged handle is actuated and leans in described thrust block seat, describedly connect adaptive being configured as in surface: the described normal of surface on any point on described surface that connect,---its rotation axis with described connecting rod is crossing---orientation all along a direction.
[21] when the lock actuation mechanism was in its contact and arranges, connecting rod was remained on the settling position by holding device on the one hand, and actuate the connection end that is hinged handle on the other hand.
[22] described connection end is used to actuate the direction of the power of described bar, passes the rotation axis of described same bar, and can avoid described hinged handle can be applied to any moment of torsion on the described connecting rod.
[23] therefore, make described bar join actuating of mechanical spring without any meeting around the power of its rotation.
[24] therefore, for example can increase the motivator of hinged handle on described thrust block seat, and thereby increase described contact each other against pressure so that improve to disconnect or heating property.
[25] except that connecting the end against the frictional force that thrust block seat produced, the increase of power is inoperative to the rotation of trip lever.Mechanical spring is provided for overcoming described frictional force, and thereby allows connecting rod to rotate when mechanism's release the time.Therefore, regardless of wanting applied pressure on contact, can use identical holding device.
[26] therefore same lock actuation mechanism can be used in all types of circuit breakers, and the number of the contact that no matter need control how much, also regardless of the type of stipulating the circuit breaker of utilisable energy for actuator.
[27] in fact, for example four-pole circuit breaker must apply a bigger power compared with one pole or double-pole cut-out on thrust block seat.
[28] same, for example quite sensitive differential switch only provide several milliamperes of electric currents to actuator, and disconnect can provide several peaces when electric fault takes place.
[29] current mechanism is applied to all types of products,, can reduces the risk of manufacturing cost and minimizing setup error, simplify production process simultaneously from the angle of manufacturer.
[30] in addition, the annex use that often also combines with described circuit breaker.Described annex is inlaid on the circuit breaker, make with described breaker mechanical link together so that survey the release of described circuit breaker.Certainly, described annex should the adapt to described circuit breaker lock actuation mechanism of---annex connects thereon---.Therefore, the present invention can also only need that a unique cover annex---is adapted to this lock actuation mechanism---and be applied to all kinds of circuit breakers.
[31] preferably, the connection surface of connecting rod is formed by a cylindrical portion, and described cylindrical portion is centered on the rotation axis of described connecting rod.
[32] making a concerted effort of the lip-deep contact force of described connection, from mathematics by described rotation axis and be a mode of implementing above-mentioned principle.
[33] same, the connection end of hinged handle can be formed by a cylindrical portion, and described cylindrical portion is centered on one that parallels with the rotation axis of described connecting rod.
[34] the described connection end that obtains like this helps avoid undesirable friction phenomenon in the lip-deep linear contact of described connection.

[74] this sentences the profile mode two contacts 1 and 2 only is shown, and certainly, controls simultaneously under the situation that the not homophase of the disconnection of different circuit or same circuit disconnects in hope, can consider to replenish contact pair and above-mentioned contact to layout with aligning.
[75] in addition, contact 1 and 2 is also disconnected spring 34 (representing with a moment of torsion arrow at Fig. 1) by one to Fig. 3 actuates, thereby separates to each other.
[76] described just lock actuation mechanism will be guaranteed the control to contact 1 and 2.
[77] this mechanism has a hinged handle 3, and described hinged handle is formed by a hand lever 4, and described hand lever is installed on one 5 that fixes with respect to casing rotationally, and described casing plays a frame herein, to support the different component of described mechanism.Hinged handle 3 also has a slave connecting rod 6, and this slave connecting rod 6 is connected with hand lever 4 by a rotation axis connector, so that the rotating drive slave connecting rod 6 of described hand lever 4 moves.Described slave connecting rod has one and connects end 7, and described end represents with a circle in the schematic diagram of Fig. 4 at Fig. 1, and it forms by cylinder enforcement, and described cylinder extends to the view plane of Fig. 8 perpendicular to Fig. 5.
[78] activity of hinged handle 3 makes it have two extreme positions: an interlocking position (Fig. 1 and Fig. 5) and a unlocked position (Fig. 3 and Fig. 8), described two positions limits about 90 ° angular motion amplitude of hand lever 4.One spring 13 (representing with a moment of torsion arrow to Fig. 3 at Fig. 1) is actuated hinged handle 3 towards its unlocked position.
[79] in addition, described mechanism has an intermediate bar 8, described intermediate bar is connected with movable contact 2 indirectly by a slave connecting rod 9, and described slave connecting rod 9 is hinged on the supporting member 10 of support movable contact 2, and described supporting member 10 winds the one spool 11 rotationally installation fixing with respect to casing.
[80] intermediate bar 8 winds the one spool 12 rotationally installation fixing with respect to casing, and be arranged such that: intermediate bar 8 touches at the rotating drive movable contact 2 in the direction and leans on fixed contact 1, and perhaps its rotating drive movable contact 2 in other direction is separated with fixed contact 1.
[81] in addition, intermediate bar 8 also has a skewed slot body 14, and described skewed slot body is arranged on the relative end of described intermediate bar and slave connecting rod 9, this skewed slot body 14 can admit with guide slave connecting rod 6 be connected end 7.
[82] in the porch of skewed slot body 14, intermediate bar 8 has a groove seat, and described groove seat is formed by a stop surfaces 15 and a sidewall 16, and described groove seat can partly be admitted and connect end 7.
[83] in addition, intermediate bar 8 is installed on the described axle 17 rotationally near one 17, one connecting rod 18 of the support skewed slot body 14.This connecting rod has one first contact surface 19 and one second contact surface 20---described two contact surfaces are arranged in the both sides of axle 17, and an ear tooth 21---, and it has a connection surface 22.Connecting surface 22 is cylindrical portion, and the rotation axis 17 of the axis of described cylindrical portion and connecting rod 18 coincides.
[84] spring of mechanism is a torsion spring 38 herein, is arranged in around the axle 12 of intermediate bar 8, and when mechanism is in the position of Fig. 1 and Fig. 5, this torsion spring 38 applies a torsion between the arresting lever 23 of a connect box and described second contact surface 20.
[85] latch 24 that is connected to intermediate bar 8 is set to be used to limit the angle stroke of connecting rod 18 with respect to intermediate bar 8.
[86] last, intermediate bar 8 supports one 25, one auxiliary rod 26 and is rotatably installed on the described axle, and this auxiliary rod 26 has one first support arm, described first support arm forms a strut 27 and has one and supports tip 28, and described support tip is used for matching with first contact surface 19 of connecting rod 18.In addition, a polarization spring 35 is set to be used for support tip 28 is actuated towards first contact surface 19.
[87] auxiliary rod 26 also has one second support arm 29, and it is used for matching with trip lever 30.
[88] first support arms 27 and second support arm 29 are arranged in the both sides of the axle 25 of auxiliary rod 26.
[89] trip lever 30 is around the one spool 31 rotationally installation fixing with respect to casing, and have one first support arm 32 and one second support arm 33, described two support arms form about 90 a ° angle herein, and second support arm has a circular wedge, are used for cooperating mutually with second support arm 29 of auxiliary rod 26.
[90] trip lever 30 can be by a motor machine pressurized strut 36 actuation movement, described pressurized strut is fixed with respect to casing, and allow a retrieving position (Fig. 1 and Fig. 5) and an extended position (Fig. 2 and Fig. 6), when---it may cause mechanism's release---, make it enter extended position when detecting electric fault from retrieving position by giving pressurized strut 36 power supplies.
[91] auxiliary rod 26 and trip lever 30 form holding device, and described holding device can be in this way by pressurized strut 36 actuation movement.
[92] rod member of pressurized strut 36 acts on first support arm 32 of trip lever 30.On described first support arm 32, beyond the part of the rod member that is used to contact pressurized strut 36, be provided with one and restore backing pin 37, described backing pin extends perpendicular to the plane of schematic diagram, and it is used for cooperating mutually with mechanical spring 38.
[93] in fact, when mechanism was in the position of Fig. 1 and Fig. 5, spring 38 applied an angle separating force between second contact surface 20 of arresting lever 23 and connecting rod 18.
[94] and when mechanism is in the position of Fig. 2 and Fig. 7, this time spring 38 makes on described position at arresting lever 23 with restore between the backing pin 37 and apply a power, restores backing pin and is in and is lower than on second contact surface, the 20 residing height.
[95] the lock actuation mechanism of just having described is moved by the mode of pointing out below.
[96] mechanism shown in Fig. 1 and Fig. 5 is in its contact position.For described mechanism is brought to described position from the unlocked position shown in common Fig. 3 and Fig. 8, must make it enter interlocking position (it is unique element that described mechanism protrudes out from casing) by start hand lever 4 from unlocked position, and with described mechanism sealed on.
[97] the rotating drive slave connecting rod 6 of hand lever 4 connects end 7 and leans 39 li of thrust block seats, described thrust block seat by stop surfaces 15 be connected surface 22 convergences and form.
[98] connect end 7 therefore along with the rotation of hand lever 4, slide in the bucket shape mouth that is formed by thrust block seat 39 up to occupying a position, on described position, it freely contacts stop surfaces 15 simultaneously and connects surface 22.From this moment, be rotated further 4 of hand levers and drive intermediate bar 8 rotations and therefore make contact 1,2 close.
[99] auxiliary rod 26 polarized springs 35 are actuated simultaneously, so that touch first contact surface 19 of connecting rod 18.
[100] because the rotation of intermediate bar 8 and thereby the rotation of second contact surface 20 of connecting rod 18, described second contact surface 20 will contact with mechanical spring 38, and will restore backing pin 37 and discharge from the constraint of mechanical spring 38 along with rotating it.
[101] therefore, mechanical spring 38 is pressurized, reaches stable contact position among Fig. 1 and Fig. 5 up to mechanism, and slave connecting rod 9 firmly is supported by in described Fig. 1 and Fig. 5.
[102] on described position, the power that connection end 7 is applied on the thrust block seat 39 at length is illustrated in Fig. 4.
[103] first component F
1Be applied on the connection surface 22, and the second component F
2Then be applied on the stop surfaces 15.
[104] when described connection end is inserted in 39 li of thrust block seats no matter its equilbrium position that reaches how, owing to connect surperficial 22 toroidals that are centered on the described axle 17, described connection end will be along a direction---and the axle 17 that described direction is passed connecting rod 18, can only transmit a component F
1Other direction of power will be by component F
2Transmit.
[105] therefore, connect end 7 and do not apply the moment of torsion that any meeting is rotated connecting rod, have only axle 17 itself to bear a power.
[106] when an electric fault occurring, pressurized strut 36 can place the extended position (see figure 6), rotate thereby drive trip lever 30, and thereby driving auxiliary rod 26 rotations.
[107] thus this cause: ear tooth 21 separates with the inlet of skewed slot body 14 under the effect of mechanical spring 38, and after this can be in place at 14 li of skewed slot bodies (seeing Fig. 2 and Fig. 7) owing to connect the end, regardless of the position of hand lever 4, intermediate bar 8 can rotate under the effect that disconnects spring 34.Therefore, contact 1 and contact 2 are separated and the circuit disconnection.
[108] stage afterwards can be seen, mechanical spring 38 acts on and restores on the backing pin 37, so that bring pressurized strut 36 back to its retrieving position, and spring 13 is actuated hinged handle 3 to its unlocked position, thereby driving connection end 7 deviates from from skewed slot body 14, so that in place, thereby be ready to new interlocking (Fig. 3 and Fig. 8) in the porch of thrust block seat 39.
[109] Fig. 9 represents a modification of described lock actuation mechanism to Figure 13.
[110] according to the mechanism of described modification except that the recovery of pressurized strut 36, identical with foregoing mechanism, the recovery of described pressurized strut 36 is not to be undertaken by acting on the mechanical spring 38 that restores on the backing pin 37, but is implemented by a special return spring 40.Described spring as Fig. 9 shown in---it illustrates from the observed mechanism of opposite side---, is actuated the end of second support arm 33 of trip lever 30 and the angle disengaging movement between the intermediate bar 8.
[111] in addition, a guide vane end stop 41 is set to be used for the stroke of limit mechanical spring 38.
[112] not diagram another modification of coming out does not relate to release, and described release is implemented by an annex, described annex be mechanism in addition and it in rotation, act directly on the auxiliary rod 26.Therefore, pressurized strut 36 and trip lever 30 can be cancelled.
[113] say more at large, the invention is not restricted to interlocking described herein and release mechanism.
