Description
Technical field
The present invention relates to a kind of locking mechanism that is used for electric device, so that the circuit of protective circuit breaker and people, this circuit breaker comprises that at least one is designed to the current collector that cooperates with one or several fixed contact.Such mechanism is movably being used for closed latched position and being used to open between the unlocked position by the circuit of electric device control.
Background technology
This electric device comprises executive component, and it can control the change in location of locking mechanism, if be suitable for, corresponding to its any release, for example owing to the situation that at least one is not suitable for keeping the electric wiring of latched position occurs.Traditionally, use link rod that executive component is connected to locking mechanism.
Traditionally, locking mechanism comprises at least one current collector by contact holder supporting, and this contact holder is along in supporting respectively with away from first pivoted between two positions of fixed contact.Between the lockup period of this mechanism, the Stress Transfer that is derived from link rod one end of executive component is arrived contact holder.
Locking mechanism is used for the energy that machinery amplifies to be provided by measuring system, and its amplification principle is based upon on the mechanical mechanism of being supplied with by spring, and its unsettled balance is guaranteed by friction stree basically.These are implemented at the above-mentioned end and the contact holder of link rod especially.
Under the situation that circuit goes wrong, mobile trigger forwards information to mechanism, and this mechanism provides by one in the measuring system, normally magnetic or heat, release when it is in the make position of contact with box lunch.This trigger comprises that permission keeps the element that is bearing in the link rod on the contact holder in locked stage and latched position.
When trigger moves and discharge the end of link rod, destroy above-mentioned friction stabilizing mechanical relation, so that allow this mechanism's release.
In case link rod discharges, the open position of implementing to be used to make contact holder return each current collector is promptly away from the device of fixed contact.
Stable for the locking mechanism that guarantees to be in the close position, it must comprise deformable structure.In known locking, possible distortion guarantees by elastic device, and this elastic device allows relatively moving and allow to implement the support pressure of each current collector to fixed contact between several parts usually.
Except the mechanical stability of the locking that is in the close position, the electrical problems when these elastic devices can also guarantee that enough pressure is avoided closing of circuit so that make circuit breaker more stable, and is avoided fixing and current collector runs down.These devices can also absorb the contact of wearing and tearing.
In some known structure, guarantee to be used to make contact holder to return open position, current collector device by two independent springs, and implement a elastic device another support pressure away from fixed contact.
Yet, also have the structure that single spring is carried out two functions simultaneously.This is the situation of the system described in patent EP0506503 of applicant.
In both cases, the assembling of lock cell comprises that the special location of spring normally is not easy automation, and therefore, aspect the assembly industryization of electric device, this is disadvantageous economically.
Under situation about spring being inserted between current collector and the fixed contact, this structure will be complicated more, particularly because the quantity of the part that will assemble according to mobile connection, and because mounting spring needs its end locking, so that function is returned in its execution.This complexity has direct influence to production cost of products.
Being used for of describing in document EP 0506503, the solution of implementing single spring also can find the assembly problem of this spring end.
Summary of the invention
One of purpose of the present invention is to reduce the industrialization cost of electric device, therefore simplifies locking mechanism itself as much as possible, with and assembling in electric device.A kind of original structure is designed to realize this purpose.
In case this newly-designed major advantage is to install locking mechanism and just avoids adjusting.
Tangible purpose becomes when realizing description below reading of these purposes and other, initial each current collector that is characterised in that according to locking mechanism of the present invention is connected to contact holder rigidly, and be connected to contact holder by connecting the elastic device to be used to implement the support pressure of each current collector on fixed contact, in a single day thereby guarantee to occur described supporting, first pivot moves with respect to current collector/fixed contact support region.
The rigidity that current collector/contact holder connects allows the quite technical scheme of simplification, and course of industrialization, this course of industrialization is only managed rigidity and compact assembly, rather than as the solution of most prior art, manages the independent part of several formation locking mechanisms.
For the stability of the locking that guarantees to be in latched position, according to original solution fully, the initial pivot of contact holder itself moves with respect to current collector/fixed contact support region.In other words, replace providing first of this mechanism to move to bring contact each other, as most prior art, identical axial distortion engages supporting, and described distortion occurs with respect to contact region.This solution allows the significant technical simplification of locking mechanism.
This mechanism can also comprise the device that moves that is used to guide first pivot.
According to first modification, these elastic devices are made of the pin spring (hairpinspring) of sending out with linear support branch, one end of this branch is fixed to the housing of electric device, the other end is perpendicular to the bending of described branch, and provide pivoted, so that in the hole of this contact holder, contact holder passes through the loose fit of sweep along this first rotation.
In this case, provide guiding by spring itself, the length of its branch obviously is constant.Therefore do not need to increase outside induction element.
Advantageously, this sweep also is used as the pivot of trigger.
And, the device that is used to return away from each current collector of fixed contact is made of the pin spring of sending out with a branch, one end of this branch is fixed to the housing of electric device, and described branch is bearing on this contact holder, and applies the action opposite with this link rod.
These return mechanisms form in the mode identical with elastic device, so that allow moving of first pivot, then, they separate with this first pivot.
This similitude also can find in the end of described branch, and this end is in fact perpendicular to the plane of motion bending of each current collector, and the end that this moment should bending is contained in the sliding channel that is formed in the contact holder.
The importance of sliding channel is and can redirects stress with respect to the branch of spring, so that this branch works on its whole length and be unpressed, for this reason, hardness is very high and be nonproductive.
Preferably, being used to implement the device of support pressure and being used to make each current collector to support respectively and sending out the pin spring accordingly away from the return mechanism of fixed contact is single part, and is connected the level that they are fixed to housing.
Thereby for single component, the only surplus next one is used for fixing the position of housing, and this has further simplified assembly.
Also preferably, described spring can connect by additional branch.This can have linear support, and it is not launching on the free-ended moving direction of current collector in fact.
In this case, because the spring of single-piece form can be provided for this reason, thereby make that to be fixed to housing easy especially in the branch of the housing that provides.
Therefore, contact holder/current collector assembly still can be thought and " float " with respect to housing, so that can move according to being not limited to simple pivotally supported compound movement no longer with respect to the direct pivoted of housing.
According to another modification, implement the flexibly mounted elastic device of each current collector on fixed contact by comprising that sending out the spring of selling branch forms, one end of this branch is connected to the housing of electric device, this branch is positioned at inactive state, when the supporting of current collector/fixed contact occurring with box lunch, this branch is out of shape by the contact holder in moving between lockup period, by the contact connection of inserting in housing or the groove contact holder is connected to housing, thereby permit it along first pivoted, and guide its moving with respect to current collector/fixed contact support region.
In this case, the branch of sending out the pin spring is not used in moving of guiding contact holder, and this moves by contact connection/housing or groove and provides.
In this stage, allow the elastic device of current collector/fixed contact support pressure not have problems.
Yet, identical branch can be positioned at inactive state, so as during its all moving by the contact holder distortion, and as the device that returns away from each current collector of fixed contact.
In the structure in front, on the one hand, identical spring is used to realize returning device away from each current collector of fixed contact, on the other hand, is used to realize the device of elastic bearing pressure.
According to a kind of situation, of sending out in the pin branch end is fixed to housing.
Send out pin branch and can also constitute in the branch of helical spring end one, its spiral core is around the contact, and other end branch for good and all is bearing on the projection above housing.In this case, the mechanical attachment of sending out pin branch and housing is complicated more, but the back will be clearer, and it has advantage between erecting stage.
According to a kind of possibility, contact holder comprises the axle journal that inserts and can slide according to loose fit in the shell of housing.
This connection can provide the mechanical function that belongs to this connection, and promptly along the moving of first pivoted and back, described connection has the feature that combines with the above-mentioned return mechanism that is used for returning when mechanism's release initial position.
This shell or groove provide guiding to axle journal according to rectilinear motion, and if be suitable for, allow the friction of current collector on fixed contact.
According to a kind of possibility, this shell comprises the wall that U-shaped is vertically-oriented, and the opening of this U-shaped opens on the direction of current collector.Therefore, this shell is not closed fully, and this can be regarded as advantage additional between erecting stage.
Also preferably, the spiral core of spring is around this U-shaped shell.
In this structure, also the position that above-mentioned complicated machinery is connected is as a helical spring tie point.
According to a kind of possibility, send out of the pin driving of pin branch by outstanding contact holder.
Providing by trigger under the situation of function, the pivot of the trigger relevant with contact holder freely can be arranged on the contact holder.In this case, preferably, this trigger around with shell at housing in the coaxial contact pivoted of axle journal that moves, described contact is from outstanding with the contact holder opposite surfaces.
Therefore, have the single of different pivots that are used for connecting with housing on the one hand, in the connecting of trigger and contact holder, comprise on the other hand at contact holder.
Contact holder comprises the inclined-plane traditionally, and one in the end of this link rod is bearing on this inclined-plane, and this inclined-plane cooperates with the ratchet of trigger, so that keep the end that is bearing in the link rod on the inclined-plane in locked stage and latched position.
By this inclined-plane, the Stress Transfer that will be transmitted by link rod between lockup period is to locking mechanism.The end that the existence of ratchet can be kept link rod contacts with this inclined-plane, so transfer function power.
According to a kind of possibility, current collector is the single part with contact holder.In other words, no longer have actual contact holder, have the mechanism that reduces one or several current collector, on this current collector, apply and be used to the stress of realizing that mechanical function is required.
According to a kind of possible structure, bimetallic strip can with only current collector or current collector in one with respect to fixed contact, opposite end integral rigidity with its support region make.
Alternatively, bimetallic strip can be the single part with current collector, and it can also simplify this moving assembly by of removing in its assembly.
In this case, near current collector/fixed contact support region, this bimetallic strip/current collector and contact holder are integrally made, and comprise sweep, and its free end is arranged across the branch of trigger.This sweep launches along the relative contact region of certain-length from the fixture to the contact holder, thereby allows the bending of enough excitation triggers.
Preferably, the branch of trigger is placed near this element or the ratchet, thereby can keeps the link rod that is bearing on the contact holder.
Comprise one or several current collector, bimetallic strip and trigger on this locking mechanism is pure, the very compact and assembling easily of this locking mechanism, and be suitable for assembly automation.This mechanism is owing to the specific connection that the is connected to housing installation of floating, thereby no longer needs the specific adjusted of any back.
At last, share some function such as pivot, return spring and the elastic device that is used for pressure support in first structure, can obtain economic fully locking mechanism.

With reference to accompanying drawing 1, locking mechanism is indicated by Reference numeral 1, is connected to executive component 2 via link rod 3.Mechanism 1 mainly is made of current collector 4, trigger 5 and spring 6.This spring is by three 6a of branch, 6b, and 6c and have two sweep 7a, the end of 7b constitutes.
For example by clip the locking mechanism shown in the accompanying drawing 1 is installed in the housing of electric device, preferably with part 6b, the level of the central portion that 6c separates with spring 6 is finished fixing.
In accompanying drawing 2, the assembly of accompanying drawing 1 presents from opposition side, and is installed among the housing B of electric device.Positioning action element 2 so that the inclined-plane 11 of 3 pairs of current collectors 4 of link rod applies action via its end 3a, rotates thereby make it be bearing in fixed contact 12 head lamp brush guard pivots.This move with respect to spring 6 particularly the 6a of its branch finish, near the operating space of the end of link rod 3 3a, support via the sweep 7a in the sliding channel 8.
In case current collector 4 is bearing on the fixed contact 12, then resilient movement by spring 6 6b of branch and the mobile distortion of finishing for the required system of the mechanical stability of locking by crooked end 7b.
In case current collector 4 is bearing on the fixed contact 12, then all locking mechanisms 1 move in the inside of the housing B of electric device.This mobile one side can realize correct contact pressure between fixing and the current collector, and if desired, can also compensate the wearing and tearing of electrical contact.
And for example shown in accompanying drawing 3a and the 3b, trigger 5 can be mounted freely on the current collector 4 around pivot 7b rotation, if so that occur overcurrent or short circuit on the line, the end 3a of the mobile release link rod 3 by ratchet 9.Under the situation of short circuit, for example, the striker 14 of traditional magnet motor M can make its counterclockwise pivoted, thereby discharges link rod 3, separates current collector 4 and fixed contact 12 then under the influence of spring 6 6a of branch.Current collector 4 also comprises heat bimetallic strip 13, opposite end on this bimetallic strip is fixed to it rigidly and is bearing in fixed contact 12.
When in circuit, overcurrent occurring, bimetallic strip 13 distortion and contact handle 10, this handle drives trigger 5 is rotated on the direction identical with the front, and discharges link rod 3, perhaps opens circuit.
Assembly according to locking mechanism 1 of the present invention can guarantee the pressure support of current collector 4 on fixed contact, and this finishes by using from the projection 15 of housing B generation, and clearly represents in accompanying drawing 3b.This projection 15 for example is positioned at sweep 6b, and the level of the circular portion that 6c separates with spring 6 is wherein clamped spring.
In accompanying drawing 4 to 6, present another kind of pattern according to device of the present invention.When relating to identical assembly, keep identical Reference numeral.With reference to accompanying drawing 4, executive component 2 is connected to contact holder 17 via link rod 3, and current collector 4 is connected to this contact holder rigidly, and trigger 5 is installed around pivot 18 pivotallies that surpass contact holder 17.
In this pattern, spring 16 is helical springs, and it comprises two 16a of end branch and 16b respectively, and this branch is bearing in above locking on the projection 19 of housing B, and in this case, its rectangle part by shell is represented.
Another end 16a of helical spring 16 cooperates with the contact 20 that surpasses contact holder 17, and this contact is to spring 16 pressurizations when the contact holder up time is rotated.
The core of helical spring 16 be wrapped in anti-U-shaped shape, be used to hold housing 21 above the axle journal 22 of contact holder 17.This axle journal 22 is coaxial with contact 18, and trigger 5 is around this contact pivoted.
Accompanying drawing 5a and 5b represent the operation of locking mechanism with two reverse effects, at this current collector 4 away from fixed contact 12.
In accompanying drawing 5a, specifically,, represent housing B part and U-shaped housing 21 pellucidly for task of explanation.In this accompanying drawing, the locking mechanism release, the mechanical attachment between contact holder 17 and the housing B is by 21 system specializations of axle journal 22/ housing.Action on the control lever 2 causes the end 3a of link rod 3 that inclined-plane 11 is applied action, so that closed circuit.Contact holder 17/ current collector 4/ trigger 5 assembly up time pin pivoted, axle journal 22 is to rotate freely at housing 21.
With reference to accompanying drawing 5b, along with increase is moved at the angle from top starting position, the end branch bending of spring 16.Suppose that the other end 16b is with respect to contact 19 supporting, then spring 16 stored energys.
In case current collector 4 is with respect to fixed contact 12 supportings, shown in Fig. 6 a and 6b, and it moves continuously before to suppose action bars 2 and link rod 3 in the end to be blocked in latched position, and then on the Way out of U, axle journal 22 moves in housing 21.Yet U-shaped wall inside is limited and is remained in this path.All mechanisms move in an identical manner.
As the pattern of Fig. 1 to 3, bimetallic strip 13 is installed on the current collector 4 rigidly.By contact handle 10, its distortion allows trigger 5 pivoted, and allows to discharge the end (3a) of link rod 3.Described pivoted can also trigger by the striker 14 of magnet motor M.
Then, be released in the energy that is stored in spring 16 during the rotation that the front is used for locking, and device returns its initial position, shown in Fig. 5 a and 5b.
The possibility that presents among the 7a to 7c with reference to the accompanying drawings, bimetallic strip 13 and current collector 4 only constitute the single part 4 ' of carrying out two frictions.In this case, for the bending of this band can occur under good conditions, must near current collector 4 '/fixed contact support region, finish and fix 23 to contact holder 17.
Finish bending towards action bars 2, and now trigger 5 not only comprises handle 10, and be included near the supporting zone on link rod 3/ inclined-plane 11, be positioned at the projection 10 ' of level of the axle of this bar.
Because the pattern of front has the bimetallic strip 13 that is fixed to current collector 4, this structure makes the product assembling itself not need to adjust the position of bimetallic strip afterwards.
