Another advantage according to installation switchgear of the present invention is: can be used for electric contact to the release district of sliver between thermo bimetal's alignment epoch.In known installation switchgear, the contact point that is used for thermo bimetal's calibration is arranged at the another location in the outside, inlet region of terminal connection, and can't touch via terminal.Because the thermo bimetal can only calibrate finishing under the state of assembling, after therefore in known installation switchgear, calibrating, must assign to cover the independent inlet opening of calibration contact zone with additional covering part.
In installation switchgear according to the present invention, need not above-mentioned restriction.Compare with installation switchgear well known in the prior art, this has not only saved assembled part (promptly additional cover part) but also has saved the production stage in the assembling, so the further favourable part that has produced according to installation switchgear of the present invention is simplified in the assembling of gained.
According to not band edge subcovering assembling partly and fully of installation switchgear of the present invention.The opening that connects by terminal utilizes electric contact zone to carry out thermo bimetal's calibration then, wherein the release district of sliver is used as calibration touch point.After finishing calibration, thereby place the terminal cover part appropriate location to finish installation switchgear.No longer need to be used to calibrate the independent cover part of opening.
Because arrangement according to the invention, provided further advantage: make that their external dimensions are very narrow and also can have lower resistance even the terminal connection according to installation switchgear of the present invention is configured to.This realizes by the following fact: sliver has consistent width at clamped edge and the place, release district that is attached with between the point of another lead that points to installation switchgear inside.This make to make up according to of the present invention has half the installation switchgear of width of normal width and becomes possibility.
Define module a according to DIN 43 880, be used to define the module width of installation switchgear.According to this standard, module width is integer or the half integer multiple of 17.5mm, is more accurately: a=n * (17.5mm+0.5mm), n=0.5; 1.5; 1.5; 2.0 ...
Therefore the installation switchgear that has standard module one half width has the module width of 9mm.
Sliver only has one to be used to receive many window that connect lead.Each bar connection lead that is received by the opening of sliver is kept separating by terminal openings and connected guiding device.So just might in single opening, insert and shift out many and be connected lead, and each bar lead is influenced each other.
This can be realized by the better method in another embodiment of the present invention, wherein on the clamping supporting leg of jump ring, vertically slot, thereby two part reeds that abut against next-door neighbour together, that can clamp have independently of one another been produced, described part reed is assigned to one of two terminal cover parts in each case, thereby distributes to a connection lead to be connected in each case.Because two part reeds abut against together, not have in the middle of promptly to separate yet, relatively large intermediate space or about in the central middle web, thereby the terminal that helps to form narrow structure connects, so that terminal connection according to the present invention can be installed in the installation switchgear that standard module one half width is only arranged.
In the formerly known installation switchgear, provide the separation that is separated by middle connecting plate opening in sliver, it is used for the every connection lead that terminal connects.Terminal connects the broad that just becomes like this, so when two terminals connections were installed in the installation switchgear of a standard module width, two terminals connected and must overlap.This has weakened according to required electric insulation between two terminals connections of prior art.

At first consider Fig. 1 to Fig. 5.Referring to Fig. 1, a kind of installation switchgear 1 according to the present invention has the insulating material housing 3 that is combined and form along separating plane 2a by two housing parts 2,2 ', shell 3 has positive 4, the back side 5,5 ', fix or connection side 6, make the positive 4 positive narrow sides 7,7 ' that are connected with the back side 5,5 ', the narrow side 8,8 ' in the back side, and two wide sides 9 (in Fig. 1, only showing one of them).
5 ' locate overleaf, be attached with a conventional threads terminal that is used to connect lead in the terminal connection space in shell 3, it can touch by terminal openings 11.
At 5 places, second back side, relative with thread terminal, terminal connection space 18 is provided, wherein the opening of terminal connection space 18 points to the wide side 9 of shell, the narrow side 8 in the back side and the back side 5.In terminal connection space 18, exist two terminals to connect 10,10 ', these two terminals connect 10,10 ' close to each otherly with wide side 9 lateral alternates, and on the height above the fixation side 6, lean on mutually each other.See over from fixation side 6, the first terminal connects 10 and is positioned at second terminal connection, 10 ' top.Two terminals connect in 10,10 ' each and all are fixed on appropriate position in the terminal connection space 18, and can touch to connect lead 14 (see figure 3)s.The opening of terminal connection space on four sides provides greater flexibility for the closure that connects lead 14.
Two terminals connect in 10,10 ' each all by the terminal that is distributed cover part 22, one of 22 ' cover.This is used to provide protection to be avoided the contact to the terminal connection of conduction on the one hand, on the other hand, as hereinafter mentioning, has guaranteed the no instrument that terminal connects is activated.
Connect at second terminal between 10 ' the top edge and the back side 5, the shell of the sensing equipment inside of terminal connection space 18 is that the part sheet 8a by shell wall forms.
First overlay covers terminal associated therewith respectively and connects 10 or 10 ', it points to the back side 5, and has terminal surfaces 24 or 24 ' respectively, this overlay has two terminal openings 26 and 26 ' in each case respectively, and wherein connecting lead can connect by in the terminal openings 26,26 ' each.
Second overlay covers terminal associated therewith respectively and connects 10 and 10 ', and it points to the narrow side 8 in the back side, and has respectively by nip 230 or 230 ', should can touch from the outside and manual operation by nip.Second overlay has half-open tubular cavity at its free edge place, and this second overlay can be supported on joint pin 232 or 232 ' respectively by this tubular cavity with changeing, and joint pin 232 or 232 ' is connected with the narrow side 8 in the back side of shell 3.
Naturally the support changeed that also can consider other type comes the terminal cover part is supported on the shell, for example can change rivet or the joint hinged.
Fig. 1 illustrates a kind of according to terminal cover part 22,22 ' the installation switchgear of having of the present invention, and Fig. 4 illustrates the view of the terminal connection space 18 that has removed the terminal cover part.
Terminal connects 10 and comprises sliver 102 and jump ring 12.Terminal connects 10 and places on the protuberance, this protuberance is formed on the inside of shell 3 and does not illustrate herein, terminal connects 10 and is fixed in known manner in the terminal connection space 18 by connecting plate and pin, only shows a pin 106 as example herein.
The clamping supporting leg 216 of jump ring 12 is vertically slotted along groove 218, and the result forms two reed parts 13a, 13b that can carry out clamping independently of one another, can connect lead 14 with two by these two reed parts and clamp independently of one another.
The exemplary configuration of sliver has following advantage: the power that acts on when insertion is connected lead with release in the terminal connection 10 is absorbed by described sliver as closed system, and other parts that therefore act on installation switchgear are reduced such as the power on the shell.
22 the first overlay place in the cover part, the tubular, hollow body 28 that forms import pipe is attached at each terminal openings 26 places, aims at jump ring 12.They are simultaneously as the guiding device of the connection lead 14 that is inserted into and as the reed actuating device.When cover part 22 be pressed the district on 230 pressure-driven and on the direction of jump ring 12 during around joint pin 232 rotations, hollow body 28 presses off the clamping supporting leg 216 of jump ring 12 clamped edge 120 from sliver 102, thereby at clamped edge 120 with clamp the space that produces the connection wire end 16 that is used to insert the strip off that connects lead 14 between the supporting leg 216.Fig. 3 shows this state.
If connect wire end discharge once more after inserting cover part 22 by nip 230, then the clamping supporting leg 216 of jump ring 12 can outwards be pressed out to cover part 22 on the hollow body 28 owing to its elastic force once more, and simultaneously, the end 16 that connects lead 14 is clamped to the clamped edge 120 of window 116.
Nature, the connection lead with the wire end that is rigidly connected can need not the drive terminal cover part and insert.This is from can make corresponding part jump ring 13a and 13b bending respectively when inserting because of the wire end that is rigidly connected.Yet, even the connection wire end for rigidity also must the drive terminal cover part when shifting out the connection lead.
In the embodiment shown, in the terminal surfaces 24 of cover part 22, there are two terminal openings 26, and be equipped with a tubular, hollow body 28 in the back of each terminal openings 26, it is molded on the terminal surfaces as the guiding device that connects lead and as reed actuating device (an only visible hollow body 28 in Fig. 3).In this arranges, all be assigned a terminal openings 26 and a guiding device 28 among two part jump ring 13a, the 13b being produced by the groove in the jump ring 12 218 each.Like this, if two leads are clamped in the terminal junction, then lead 14 inserts and is clamped by one of part jump ring 13a, 13b in each case from one of two terminal openings 26.Connect lead 14 separated and guiding in hollow body 28, wherein these hollow body 28 usefulness connect the guiding device of lead 14, just do not need to separate guiding or separation equipment like this in terminal connects.Particularly, do not need that opening 116 is divided into two again by web and receive the space.
So just can be with very simple and construct terminal in comparatively compact mode and connect 10.In this manner, can connect under the overlapping situation it is installed in the installation switchgear with standard module width close to each otherly need not two terminals.For example when one of two terminals are connected distribute a phase place and with its near another terminal be connected when distributing to neutral conductor, aforesaid way especially has advantage.Then particularly importantly: between two terminals connect, can not produce and be electrically connected., do not arrange according to the present invention two terminals that they may need to overlap and have the installation switchgear of standard module width to pack into close to each otherly if connecting.So have the danger that between two terminals connect, produces electric contact.By arranging that according to the present invention two terminals connect,, also can avoid reliably between two terminals connect, short circuit occurring even the two is installed in the shell of standard module width close to each otherly.
Because the elastic force of jump ring 12, protuberance 234 is outwards pressed in cover part 22 under the state of placing, so this cover part can be in definite position with the state of placing all the time.
Two kinds of functions are realized in this cover part like this: being the guidance function that connects lead on the one hand, is the function of reed actuation tool on the other hand.By equipment according to the present invention, under the condition of the externally actuated instrument that does not need to be used for jump ring, rigidity and flexible wire end can both be clamped in the terminal and can therefrom shift out once more, and this is to be in two terminals to connect under the state that abuts one another.
The nature, in the terminal surfaces 24 of cover part 22 or cover part 22 by nip in also can have extra groove so that external tool can by this groove push with the operation jump ring 12.
In addition, in terminal surfaces 24, be equipped with test opening 236.Jump ring 12 can carry out electric contact by this test opening by the use test probe.
In Fig. 1 and embodiment shown in Figure 3, the terminal surfaces 24 of cover part 22 is to the back side 5 diagonally extendings.Guiding device 28 is approximately perpendicular to terminal surfaces 24.Therefore connect lead 14 and enter of the angle of inclination decision of the angle of inclination of terminal by terminal surfaces 24.Also can expect another kind of embodiment, wherein terminal surfaces 24 is similar to abreast with the back side 5 and extends, and guiding device 28 tilts with respect to terminal surfaces 24.Connect lead 14 and insert of the angle of inclination decision of the angle of inclination of terminal by guiding device 28 opposite end sub-surface 24.
Can come production cover part 22 easily with the plasticity injection mo(u)lding by an injection process.
Fig. 5 illustrates another embodiment according to installation switchgear of the present invention, and wherein parallel with wide side insulation board inserts two terminals and connects between 10,10 '.Figure 6 illustrates a special embodiment of insulation board 244.This insulation board 244 is made up of two parallel- plates 247 and 248 with different length basically, they at free powder end by connecting plate 249 combinations, so constituted the U-shaped of supporting leg with two different lengths.Insulation board 244 inserts between two terminals connections 10,10 ' as follows: cover lower terminal connection 10 ' than 248 of weak point in two plates, the centre of these two plates sensing installation switchgears than 247 long covering upper terminal connections 10 in two plates.In addition, also be attached with pin 250 on plate 247,248, insulation board 244 engages by the respective slot of pin 250 with housing parts 2,2 ' inboard, and therefore immovably remains between two terminals connections 10,10 '.
Use insulation board 244 shown in Figure 5 can avoid two any contacts between the terminals connection 10,10 ' more reliably, thereby also can avoid the electric contact between the two.In addition, insulation board plays the effect of mechanically stable, and for example it can prevent that terminal from connecting 10,10 ' and laterally sliding to wide side 9 and enter the inside of switchgear.
In addition, in embodiment, in the enclosure wall section burst 8a of lower terminal connection 10 ' top, be shaped on and adjust opening 246 according to Fig. 5.By this opening, can tool using enter the inside of switchgear from the direction of terminal connection space, for example be arranged near the adjusting device of adjusting the opening 246 of for example adjusting screw in order to touch.
Shown embodiment illustrates the present invention in the mode of example.Shown example embodiment can the present invention not constitute any restriction.Like this, also can consider, for example two terminals be connected not have on the bias close to each otherly and arrange, even also it is on the identical height of relative fixed side 6.The terminal cover part 22,22 ' of the restriction of box-like shown in being subjected to is not an actual configuration.Particularly second overlay can than shown in longer.In a word, terminal connection 10,10 ' can be arranged in other position of the narrow side 8 in the back side, for example is in position farther on the direction of fixation side 6.
As mentioned above, be that example describes the present invention with the installation switchgear of shell construction, wherein two shells combine along the separating plane that is parallel to wide side.Nature, the present invention also can realize with the installation switchgear that adopts base designs, its shell by two parts along the separating plane be combined into that is parallel to fixation side.
Similarly, can consider following embodiment, wherein do not provide additional thread terminal to connect, but the terminal that has specially according to tool free of the present invention connect according to installation switchgear of the present invention.In this arranged, terminal connects also can be configured to the connection of extension spring type or insulation displacement.
Now consider Fig. 7 and Fig. 8.
Fig. 7 illustrates the partial sectional view according to the terminal connection space 18 of another installation switchgear 1 of the present invention.Wherein only showing the first terminal connection is that lower terminal connects 10.It is that upper terminal connection 10 ' has corresponding design that second terminal connects, but the second terminal cover part that is associated with it has the spacer region of shortening.
The wide side 9 of shell that terminal connection space 18 is insulated the shell 3 of material is limited in the side, also promptly points to wide side.
Formed opening 20 by the opening in the back side 305 of housing parts 2, can touch the terminal that is fixed in the terminal connection space 18 by this opening 20 and connect 10 to connect lead 14 towards positive 304 terminal connection space 18.Positive narrow side 7 beginnings are adjacent in shell side with the part sheet 356 at the back side 305.This produces opening 20 in 305 places overleaf, the zone that produces opening shell side from the front narrow side 7 towards between the narrow side 8 of the end and the back side of outer part sheet 356.
Because another opening at the narrow overleaf side of housing parts 28 places, the narrow side 8 in the opening 20 extend through back sides of terminal connection space 18 and the engagement edge between the back side 305 and enter the narrow side 8 in the back side.This helps giving greater flexibility for the closure that connects lead 14.
The terminal that will be described below connects 10 terminals that correspond essentially among aforesaid Fig. 1 to Fig. 6 and connects.Terminal connects 10 and comprises sliver 102 and jump ring 312.Terminal connects 10 and is fixed on by web 104 and pin 106,108 on the position in the inner terminal connection space 18 of wide side 9 in original known mode.Thereby the locational terminal connection 10 that will be fixed in the terminal connection space 18 places between the narrow side 8 in the back side and back side installation side 6 in engagement edge district.
The sliver 102 of terminal connection 10 comprises connection terminal 112 and adjacent release district 114.Connecting terminal 112 places, it has window 116, and window 116 has bearing edge 118 and the clamped edge 120 relative with bearing edge 118.This clamped edge 120 is in and connects terminal 112 to the position that discharges district's 114 transition.
In the embodiment that terminal shown in Figure 1 connects, on bend free end elongation at the second U-shaped supporting leg 222, to form released strip 226.Released strip 226 forwards are connected to the second U-shaped supporting leg 222; Itself and latter's near normal ground point to the direction of window 116 and outstanding thereon.
In this embodiment, adjacent during arc sheet 214 with first's clamping supporting leg 217, this first clamps supporting leg 217 and becomes second portion clamping supporting leg 218 in the bending of curved edge 219 places, so first clamps supporting leg 217 and second portion clamps supporting leg 218 each other in the obtuse angle.The opening at this obtuse angle points to the direction of insertion that connects lead, the curved edge 219 approximate centres that clamp supporting leg 216 that are in.
The terminal cover part 22 that the opening 20 of terminal connection space 18 is rotatably connected to housing parts 2 covers.
First's body 322 comprises first overlay 323, first overlay 323 covers terminal connection space 18 in the bottom with installation side 6 adjacency of narrow side 8, and make the corresponding component of approximate tubulose reach joint pin 232, wherein first overlay 323 rotatably connects at these joint pin 232 places.First overlay 323 has by nip 330, and it can touch and be manually actuated from the outside.
Near the free end of pressing nip 330, first overlay 323 is connected with spacer region 338 via the intermediate 325 that points to enclosure, spacer region 338 also extends with the narrow side 8 in the back side on 305 the direction overleaf abreast, and covers terminal connection space 18 on the top adjacent with the back side 305 of narrow side 8.
At the free end of spacer region 338, be equipped with the film hinge 352 that has connected above-mentioned enclosure portion 354 rotatably.
This is the partly overlapping at least flat board of parts 356 at the shell side place at its free end and the back side 305.The enclosure portion 354 of back side shell side and parts 356 form the back sides 305 jointly like this.
If terminal cover part 22 is subjected to rotating on the direction of device interior by the pressure effect on the nip 330, then enclosure portion 354 will be overleaf the back of parts 356 at 305 shell side place slide, and guided in the mode that moves abreast with the latter by rocking bar shape guide groove 360.In this process, the angle between enclosure portion 354 and the spacer region 338 changes.
Like this, each other in acute angle, the opening of this acute angle points to the inside of shell according to the enclosure portion 354 of its closed position of Fig. 7 and spacer region 338.In the position according to Fig. 2, when terminal cover part 22 changed the inside of shell over to, enclosure portion 354 and spacer region 338 formed the obtuse angle, and the opening at this obtuse angle points to enclosure.
Make terminal cover part action and during around joint pin 232 rotations, enclosure portion 354 and spacer region 338 are rotated motion around film hinge 352 with also being relative to each other.
By film hinge attached between enclosure portion 354 and the spacer region 338, enclosure portion 354 can be overleaf parts 356 back at 305 shell side place move abreast so that the mode of saving the space is approximate.
The connection lead is guided through the terminal openings 26 in the terminal cover part 22, and after leaving tubular opening 28, runs into the clamping supporting leg 216 of jump ring 312.
If connecting lead is rigid wire, then can only utilize to connect lead and the clamping supporting leg 216 of jump ring 312 is opened from clamped edge 120 extruding, arrive following degree: make to connect in the free end and the window 116 between the clamped edge 120 that lead could insert and be clamped in clamping supporting leg 216.
Flexibly connecting under the situation of lead, window 116 must be opened at first in another way.
This rotation by terminal cover part 22 realizes.
Near tubular opening 28, terminal cover part 22 is loaded with at intermediate 325 places points to the front end 30 that clamps supporting leg 216, and it is as the reed drive unit.
Owing to clamp the effect of the elastic-restoring force of supporting leg 216, the latter is pressed to the outside with front end 30, and thus the outside is pressed in terminal cover part 22.
Because it is aimed at according to the mode that the time carrying jump ring that makes that it rotate in the cover part opens to curved edge, so the power of required cost is littler in the opening action of terminal cover part, clamps the identical size of open region maintenance in the window.
In an example, first and second parts clamping supporting leg 217 and 218 forms and is about 160 ° angle.Compare with the jump ring that has unbent straight clamping supporting leg 216, other condition is constant, and the introducing of this angle makes the required actuating force in maximum terminal aperture reduce by half.
Adopt corresponding step to separate the connection lead that has clamped.Pressure on the terminal cover part 22 separates the clamping that clamps between supporting leg 216 and the connection lead in the manner described above, and the latter can be extracted out from window 116.Owing to clamp supporting leg 216 aforesaid warp architectures, so it is also very little to be used to separate the actuating force that connects lead.
Adopt corresponding step to separate the connection lead that has clamped.Pressure on the terminal cover part 22 separates the clamping that clamps between supporting leg 216 and the connection lead in the manner described above, and the latter can be extracted out from window 116.
Scheme as an alternative, the opening action of terminal cover part 22 also can be realized by the flat recess that can buy or cross recess screwdriver 364.For this reason, the latter is inserted spacer region 338 with acute angle and be applicable to that then terminal is followed the compressional movement of screwdriver 364 and opened in the reception opening 350 (in-line, cross or spherical notch) of reception.
Although in the example of Fig. 7 and Fig. 8, only show a terminal openings 26 and a tubular opening 28, in fact can provide two or more these type of terminal openings with a plurality of connection leads in reception and the connection intermediate 325.The connection lead that all have connected all can be clamped supporting leg 216 clampings by it by public jump ring.When terminal cover part 22 was driven, all leads that connected were all discharged simultaneously and can be separated simultaneously.
By Fig. 7 and Fig. 8 among the embodiment as sketch, the terminal cover part 22 that has first's body 322, hinge 352 and enclosure portion 354 is made up of two kinds of materials with different mechanical attributes at another.
They can mutually combine in two composition injection mo(u)ldings are handled.
Consequently firmly/soft mixture.Hard component constitutes main component.First's body 322 is promptly made thus.It is used for actuating force is passed to jump ring 312, and avoids in this process or make the thorough bending of this composition minimize at least.
Soft component is used in the zone of hinge 352 and enclosure portion 354.
This provides required flexibility for hinge, makes it can easily regulate angle between enclosure portion 354 and the first's body 322 angle during 22 motions changes in the terminal cover part.
In this embodiment, hinge 352 needs not to be film hinge.This is because the activity of hinge can needn't only depend on the thickness of hinge to guarantee by the selection of flexible material in the hinge area.
The elasticity of enclosure portion 354 also help to make its with the back side 305 abreast in rocking bar shape guide groove 360 when the narrow side 7 in front moves, can bend to a certain degree, thereby can be placed on the back side 305 easier and comparatively compactly.
On the whole, this makes enclosure portion 354 can guide more closely at 305 places overleaf, thereby saves bigger space during the rotation of terminal cover part 22.
