Description
Technical field
The present invention relates to a kind of low voltage switching device (for example line protection switch, failure current protection switch, power switch, contactor (Schuetz) or motor protection switch) of the preamble according to claim 1; It has the plug in terminals device (Steckklemmvorrichtung) that is arranged in the housing; Wherein the plug in terminals device has the terminal flexible member that at least one terminal connects framework and has terminal leg; And form terminal through first leg and connect framework; First leg through connection leg with let out electric leg (Ableitschenkel) conduction and be connected; Wherein between three legs, provide terminal and connect the chamber, and be extended with plate (Anschlusssteg) at first leg with letting out between the electric leg (it has the terminal section), it is vacated and is used to hold the free-ended through hole of connection conductor; And the terminal flexible member is arranged in plate place like this, makes through the chucking power of terminal leg in the terminal connection that is contained in the conduction that can be provided for the end on the free end in the through hole that connects conductor.
Background technology
By the known installation switching device of prior art such as line protection switch, failure current protection switch or motor protection switch.In document DE 102006047254B3, DE 102007043801A1 and DE 102007044069A1 this device is disclosed for example.
For example line protection switch comprises at least one contact site in its enclosure interior, and it has at least one fixing and a contact activity, can break off and closed current path from the input terminal to the lead-out terminal through them.Contact site is handled by the switching mechanism with convergence part usually.Line protection switch can comprise trip gear in addition, the quick release of thermal overload release or magnetic for example, and it acts on contact site or switching mechanism when short circuit current or fault current in current path, occurring, make to break off contact site.
In order to be connected, in this installation switching device, except the bolt terminal, also use the joint Terminal of non-bolt with the connection conductor of outside.Can use plug in terminals or balancer terminal (Federzugklemme) as terminal component at this.They can obviously simplify the connection that connects conductor on the principle, but the installation switching device of the at present known joint Terminal that has non-bolt also receives the use restriction.
The joint Terminal of non-bolt utilizes terminal to connect framework and implements like this, makes it possible to introduce and take out the connection conductor without instrument ground.Plug in terminals through being in the device case of being processed by insulating material has flexible member realization this point in framework inside; Flexible member is pressed to the conductor of introducing through shell nozzle; Wherein conductor is in conductor supporting (Leiterauflage) and locates, and conductor supporting is connected with the current path of device.Electric current, especially overcurrent or short circuit current should not discharged through flexible member (its processed by spring steel usually and therefore have low conductivity); But it should always connect framework or mobile through conductor supporting through terminal, and therefore it be a part or coupled the connecing of framework.Therefore framework and flexible member acting in conjunction form the contact device and the holding device of the insertion section of conductor.
Under disadvantageous situation, for example because the bending of pulling force or conductor possibly cause the active force in the conductor that is inserted from external action, it possibly cause end conductor from the conductor supporting of framework, to be lifted away from least in part.Cause the big electric current longer time or that do not expect on the relatively poor flexible member of conduction in this case so because with the interruption that contacts of conductor supporting.Possibly desirably not heat the flexible member of high ohm thus tempestuously, this possibly cause the negative effect on installation switching device.Heating possibly cause forming flame under extreme case.
Summary of the invention
Therefore the objective of the invention is so to provide such plug in terminals Unit Installation switching device that has, make in that the fail safe of device obviously improves aspect overheated because external force acts under the situation that the conductor upper conductor is lifted away from from conductor supporting.
The installation switching device of this purpose characteristic through having claim 1 according to the present invention is existing.
Implement the improvement project of this device in the dependent claims.
The form of implementation that has plug in terminals Unit Installation switching device according to the present invention is included in the terminal flexible member that at least one terminal in the housing connects framework and processed by spring steel, so the terminal flexible member has low conductivity.The terminal flexible member has at least one terminal leg.Form by three legs on the terminal connection frame principles.This first leg through connection leg with have the electric leg of letting out of terminal section conduction ground and be connected like this, make between three legs, to be formed with terminal connection chamber.At first leg and let out and be extended with the plate that is used for the terminal flexible member between the electric leg in addition, it designs like this, makes it vacate a through hole, and it also can form in flat plate on window type ground.Exposed free end passes the fixed terminal that through hole can direct into set connection conductor.Now in passage, grip by means of the terminal flexible member that is arranged in plate place usually, this is because terminal leg is directed like this, makes its elastic force or chucking power will connect conductor and presses to conductor supporting or also have the terminal seamed edge.
Can apply power to conductor from the outside now, it reacts on the chucking power of terminal flexible member and therefore can cause that conductor no longer abuts in terminal seamed edge place.This possibly cause end conductor to be lifted away from from conductor supporting.Can move at this end conductor, and not bump against additional supporting place of metal.Only, just realizes conductor the supporting that this is additional when reversing very tempestuously or be out of shape.Electric current only arrives switch through flexible member from conductor in the centre position, and flexible member is poorly conduction and heating consumingly mostly just.This heating possibly reach and cause forming flame and have disaster hidden-trouble.
Construct from the height that has seamed edge on the connection leg on the composition surface that the first long leg direction tilts through connect support component in the chamber at terminal, now through installation switching device according to the present invention, advantageously react on this through the plug in terminals Design of device in other words with projecting upwards.Through the composition surface that support component forms the backstop to the free-ended tip of conductor is provided at this.Advantageously realize thus; When conductor because outside power effect, for example since in the electric current cabinet inflexible layout or because that cable is tied up bar is fixing when conductor supporting or terminal seamed edge are lifted away from and lose contact, conductor dbus crosses that formed backstop can no longer further squint and by stable.And in not according to form of implementation of the present invention; Conductor is pressed onto on the terminal springs and follows the above-mentioned negative consequence of heating (this possibly occur; Because end conductor is not to be completely fixed in the common plug in terminals structure), prevent the location of mistake of not expecting and resist conductor to be lifted away from through support component according to the present invention at the terminal seamed edge through support component (it is similar to from the terminal bottom and extends upward).
Support component is processed by the material that has good electrical conductivity in particularly advantageous form of implementation of the present invention, in any case it all should be better than the conductivity of terminal springs, and support component is connected with framework.Not only form backstop and be used for the auxiliary fixing member of conductor element through support component in this case, and reliable second contact point that is additional to the terminal seamed edge that forms conductor supporting additionally is provided.Realize the low ohm clamping of conductor and the heating that inhibition possibly cause forming flame thus.
Therefore through inclination (it presses to conductor supporting with end conductor), also externally prevent that conductor is lifted away from from conductor supporting under the situation of power effect in the terminal bottom according to appropriate location of the present invention.If should implementing by fixing metal material by good conductive of end conductor for example as the part of framework, then forms reliable second contact point thus except conductor supporting.Realize the low ohm clamping of conductor thus and suppress to form flame.
For the structure of support component, realize that different favourable designs is possible.An embodiment of support component can be arranged to, and it is configured to obliquely on the direction of long leg directly, and seamed edge extends to the contact pin the terminal chamber from connection leg.
Therefore the design that has the contact pin of inclination is particularly advantageous, and this is because this is formed slopely the backstop of the conductor that also is used for different diameters, makes the plug in terminals device can many-sided be used for different conductor thickness.
The contact pin of processing according to this form of implementation is approximate to be extended upward from connection leg as the element of being cut.For the situation that the terminal-framework material is made of metal, contact pin also can be welded.When terminal-framework was embodied as sheet metal bending part, contact pin can and be bent upwards to inclination by punching press together when making terminal-framework.It is simple especially making so.
Alternatively also can form this upwardly extending obliquely contact pin thus, promptly connection leg is formed by two or more portion's sections that extend in parallel, and wherein upwards bending of in the position portion section that is fit to, bending perhaps otherwise are shaped.
Support component can form through portion's section that terminal connects the connection leg of framework in another embodiment, and this section arching connects in the chamber and corresponding to recess handsome in appearance (Delle) to terminal, and it can extend on terminal connects the whole width of framework.But must in the position that when the terminal seamed edge is lifted away from, can recline arching portion be set according to structural consideration at the conductor that is inserted at least.Can when making terminal connection framework, make arching portion in the process at bending ram once more highly beneficially.
Another form of implementation is arranged to, and support component itself forms nonconducting convexity at the place, inboard of housing wall, its inserting end seed cell and approximate extending in the frame plane.

Fig. 1 illustrates the fragmentary cross-sectional view that connects framework 18 according to the terminal that has plug in terminals Unit Installation switching device of prior art.The plug in terminals device that illustrates there comprises the isolating material housing 3 of hull shape shell type.Assemble by two housing half shells at this form of implementation middle shell 3, they along around closing line assembling and interconnect at the state of assembling, for example through riveted joint, but also through bolt connect, bonding, welding etc.Closing line extends in the plane of the flat or flat side members that is parallel to housing.This housing of this installation switching device is processed by the plastics die casting usually, and this provides in above-mentioned frame mode.
But the invention is not restricted to have the installation switching device of the housing of hull shape type.But it also can use in the installation switching device that has other housing form (in the for example present sandwich type element).
Fig. 1 illustrates according to the end view in the terminal accommodating chamber that has plug in terminals Unit Installation switching device of prior art; Its housing 3 this (figure on not shown) by two flat side members in other words half shell form; They have closing line around ground except the terminal covering 22 of front, be introduced in the housing with its free end 15 through terminal covering 22 conductors 14.The shell-side face of housing is divided into further from the shell-side face 4 of observer's back with more near the shell-side face 5 of observer's front.Shell section under pointing to has retaining element at least and therefore forms fixation side 6.
The observer sees the inboard 9 of flat side members or case member in the housing of opening 3 in Fig. 1, arranges that above that the terminal of non-bolt connects framework 10, and it is with flexible member, here terminal springs 12 is connected.The terminal of non-bolt connects framework 10 and mainly has the U-shaped that has long leg and short-leg, and they laterally connect through connection leg 222.Terminal connects these sections of framework 10 as bus-bar (Stromschiene), and conductor 14 is electrically connected in enclosure interior through the parts of bus-bar with other formation current path.Near the long leg that is positioned at the back side of shell forms roughly vertical last turn of bilge 224, and the terminal seamed edge 120 with conductor supporting section is molded into the second short-leg place, the electrical connection that second short-leg turns to conductor 14 and foundation is mentioned in contact.Let out electricity section 114 and be positioned at terminal seamed edge 120 back sides and a therefore direct part as leg short, that roughly vertically extend.
This shell body 3 has opening on narrow side 4,5, pass opening and can touch framework 10, and terminal connects chamber 18 and is positioned at framework 10 inside, so that the opening that passes through of fixed conductor 14 is introduced in the free end 15 in the terminal connection chamber 18.Form free end 15 fixing of conductors 14 through terminal springs 12, the splicing ear of the fixed-site that is used to provide essential, terminal springs 12 is pressed to the free end 15 of conductor 14 the terminal seamed edge 120 of framework 10.Terminal springs 12 supports and is fixed in addition plate 112 places by means of supporting 104,104 ' on the inboard of flat side members 9.Plate 112 directly is arranged in the far-end of short-leg at framework 10 places, wherein be used for the breach formation of the through hole of conductor 14 through the window-shaped of plate 112.Be contemplated that alternatively plate 112 also is arranged in turn of bilge 224 places.
But not shown here other the retaining element, for example axle journal etc. that is used for terminal springs 12 that possibly exist.Terminal springs 12 has supporting leg 212, and terminal springs 12 utilizes supporting leg 212 to be fixed on plate 112 places with supporting.Support can realize like this, and promptly supporting leg 212 is at its free end chamfered edge and utilize seamed edge to abut in the portion that passes through 118 of plate 112 or locate.Be connected with elbow 214 at supporting leg 212 places and locate joint Terminal leg 216 at it.This terminal leg 216 puts in the through hole that is used for conductor 14 so muchly on the direction of the terminal seamed edge 120 that plays the bearing effect, make its free end be guided and pass conductor 14 clamped and location.Be placed in device generation desired low ohm contact to current path at terminal seamed edge 120 places through the conduction of end conductor 15 at this.
Spring pressure or clamp pressure remain on conductor 14 in its position.
The opening that terminal connects chamber 18 here hides through the terminal covering 22 that is pivotably connected with housing 3; Its form with tubulose recess 328 provides the path of conductor 14 in the terminal chamber 18; Path 328 also to be connectedly connects the guide of the connection conductor 14 at framework 10 places at terminal with acting on, and connects conductor 14 and after through tubulose recess 328, is running into the terminal leg 216 of terminal springs 12 and such as stated clamping.
Through making 22 swings of terminal covering, the through hole in the connection conductor of flexibility in the plate 112 must be opened in case of necessity.Terminal covering 22 carries the nose 30 that points to terminal leg 216 near tubulose recess 328, and it is as the elasticity manipulation device.Nose 30 can certainly be other outstanding part or parts, especially also can be formed the function of nose 30 by rim ground around the contact pin of the outlet of tubulose recess 328.The elastic force that resets through terminal leg 216 is pushed nose 30 and outside thus press terminal covering 22 with terminal leg 216.Through the pressure on the pressure face of terminal covering 22 terminal covering 22 is inwardly swung, and terminal leg 216 is left by terminal seamed edge 120 pressures so muchly, make and expose the through hole that draws in connecting conductor 14 or its free end 15 through nose 30.
Correspondingly unclamp the connection conductor of clamping.Be pressed onto and cause it on the terminal covering 22 to swing on the direction of enclosure interior and unclamping terminal leg 216 and the clamping that connects between conductor 14 or its free end 15 with above-mentioned mode, thereby free end 15 can be pulled out from through hole.
The professional knows how alternatively also to cause the motion of opening of terminal covering 22 through slit common on the market or cross recess screwdriver.
Although according to path 328 only shown in the view of Fig. 1 to Fig. 5, can certainly be provided with two or more such connecting holes and recess, be used to hold and connect a plurality of connection conductors.The connection conductor of all connections can pass through its terminal leg 216 clampings with common terminal springs 12.The conductor of all connections is discharged simultaneously and can be unclamped simultaneously so when manipulatable end subcovering part 22.But also can use the terminal springs that has corresponding to the terminal leg of the number of attachable number of conductors.Can remove or add each then and connect conductor, and not interrupt to introduce the chucking power on the end conductor with fixed clamp at remaining.
Oscillatory through the terminal covering also provides the possibility of deviation possibility location of mistake in other words for conductor 14 when applying the pressure that reacts on elastic force, it possibly cause end conductor 15 to be lifted away from from the conductor supporting position at terminal seamed edge 120.For example as shown in Figure 1; On the direction of power, act on 14 last times of conductor clockwise in arrow P; The end of tubular passageway 328 is formed for the supporting or the point of rotation of end conductor in a way so; And this end can be left from terminal seamed edge 120 pendulum equally clockwise, interrupts connecting the low ohm contact of conductor to terminal seamed edge thus.
Be lifted away from from conductor supporting position in order to resist end conductor at terminal seamed edge 120; A kind of plug in terminals device is proposed according to the present invention; Be used for the application of above-mentioned housing 3 at installation switching device; Yet be modified in the content shown in Fig. 1 therein; See Fig. 2 to 5, make that connecting the height of seamed edge from the connection leg 222 on the composition surface 401 that the direction that has at first leg 224 tilts of support component in the chamber 18 at terminal extends upward, wherein when the power of the chucking power effect that is in reverse to the terminal flexible member is imported on the conductor; Composition surface 401 is formed for the backstop of tip 15 ' of the free end 15 of conductor 14, and composition surface 401 connects facing to the terminal of the conduction of terminal section 120 anchor portion 15.
As shown in Figure 2; The form of implementation of this support component can be configured to contact pin 410; Its from connection leg 222 extend upward and on this tiltedly is being also referred to as long leg 224 directions of turn of bilge tilt, first leg 224 that connection leg 222 splicing ears connect framework 10 with let out electric leg 114.Showing as comparing with Fig. 3; Especially therefore the structure of this contact pin 410 that has an inclination is favourable, this be because in form of implementation shown in Figure 2 directly from connection leg 222 upwardly extending contact pin 410 through being formed slopely the end conductor 15 that is used for different-thickness and the backstop of conductor 14.Thinner conductor can be with the scope of through hole by rotation or motion more consumingly under the conductor situation of 14 last times at Fig. 3 to import power at the elastic force that reacts on terminal springs 12, and has been resisted against the backstop that forms through contact pin 410 its 401 places, composition surface in other words in advance at the thicker conductor shown in Fig. 2.
As long as especially when contact pin 410 by connecting with terminal that framework 10 identical materials realize and when having satisfactory electrical conductivity; Obtain advantage; The composition surface 401 that promptly (is additional to terminal seamed edge 120) through contact pin 410 provides second electrical pickoff at terminal-framework 10 places: through this contact point current path is continued; Otherwise it from conductor 14 through terminal seamed edge 120 with let out electricity zone 114 and continue through connection leg 222, and current path no-go end sub-spring 12 guidings to last turn of bilge 224.
The problem that this outer conductor is lifted away from is tangible in Fig. 1: show that through the frame arrow power that reacts on elastic force imports there, its as cause shown in the broken circle terminal conductor 4 in other words the free end 15 of conductor 14 be lifted away from and instead conductor pressed to the leg 216 of terminal springs 12 from terminal seamed edge 120.Produce the overheated problem of low ohm terminal springs 12 thus, disaster hidden-trouble has therewith interrelated.
The support component of design according to the object of the invention also can be through having other is realized.Produce the variant of the design of in Fig. 2, implementing of the present invention thus; Contact pin therein 410 is molded into connection leg 222 places integratedly; This for example can be welded on the metal framework through bending ram or through corresponding metal contact pin and realize, i.e. contact pin 410 forms through upwards being formed in the terminal connection chamber 18 of segment section of connection leg 222.This is possible when the two or more portion's section that extends in parallel 222,222 ' formation connection leg 222 as shown in Figure 3 so especially.In other words: when l shaped incision was introduced in the connection leg 222, fish plate can be bent upwards and be formed contact pin 410.Also necessarily possible be, because the frame width of confirming is to cut out the slit of U-shaped in the flat connection leg 222 and the fish plate that therefore cuts upwards points to terminal and connects in the chamber 18.
Have possibility in addition, i.e. connection leg 222 archings as shown in Figure 5 of terminal connection framework 10 connect in the chamber 18 to terminal, and wherein portion's section 420 of arching is shaped like this, and the composition surface 401 that promptly tilts is similar to the composition surface 401 of the contact pin 410 in Fig. 2 and 3 and constructs.
The support component relative configurations is the parts that terminal connects the conduction of framework 10 in Fig. 2, the embodiment shown in 3 and 5, makes that current path can be by continuation formation through the support component that forms like this when causing conductor 15 by when terminal seamed edge 120 is lifted away from.
And support component suitably is configured to nonconducting protruding 400 of the inboard of flat housing wall in the embodiment that substitutes shown in Figure 4.This means, the such structure of one or two in hull shape spare or the housing component, promptly protuberance 420 is charged into the terminal chamber 18 from shell plane protrusions and described in front position.The composition surface 401 of portion's section 420 of arching in this case is positioned at otherwise is provided with the position of contact pin 410.This solution can easily realize under the situation of the hull shape spare that uses die casting.
But this form of implementation is nonconducting support component, and it can not be used for end conductor 15 for the purpose that second contact point is provided.But so the moulding and the geometry of the support component of design are such, make that conductor also advantageously prevents according to the present invention to be lifted away from from terminal seamed edge 120 by means of nonconducting protruding 400 fixed positions thus when power acts on conductor 15 from the outside.
Therefore through also realizing this purpose in the form of implementation shown in Fig. 4, prevent that current path from directly being formed on terminal springs 12 by conductor 15, this possibly cause the disadvantageous heating of the terminal springs on the above-mentioned meaning.
Also comprise the combination in any of preferred form of implementation and each design characteristic or improvement project in this present invention, as long as their are not got rid of each other.
