Background technology
A kind of as can be known ordinary terminal connects from EP1575130, wherein has a plurality of insertion openings and a grasp opening in a contact frame.First free end that clamps reed is clamped in the grasp opening of contact frame, and its second free end is divided into many finger-shaped extensions corresponding with inserting number of openings by one or more flute profile recesses.Each extension is all inserted the opening conducting by one in each case, and inserts in opening at each, by an extension lead is clamped in each case.Be formed with the coupling part in contact frame, it is used for another electronics output lead is attached to switchgear.Clamping reed is supported on the bearing edge of transition portion between contact frame and the coupling part.The coupling part is crooked on the direction of insertion that connects lead.In connecting, in contact frame, only there is web to can be used for current path from the connection lead clamped towards the coupling part according to the terminal of EP1575130.Correspondingly bigger from the contact resistance that is clamped to the connection lead on the other electronics output lead that exports switchgear to.Clamped connection lead is all provided the separation terminal window of separating by bus for each.So, connect the relative broad that becomes according to the terminal of EP1575130, so it can't be fitted into the switchgear that standard module one half width is only arranged.
Define module a according to DIN43880, 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.
Summary of the invention
Therefore, one of purpose of the present invention is to make up a kind of general terminal to connect, the no screw that is used for one or more connection leads connects, and described connection lead has low contact resistance, and can insert in the installation switchgear that only has standard module one half width.
In a kind of general purpose terminal connects, can realize this purpose by the described feature of claim 1.
According to the present invention, clamp connection and comprise the conductor rod that has connection end and adjacent release district.This conductor rod connects end at it and has window, and described window has bearing edge and clamped edge, and described clamped edge is in and connects terminal transition position to the release district, and is relative with bearing edge.Clamp reed and also have support leg, described support leg is supported on it on bearing edge of conductor rod.This support leg is adjacent with an arc sheet, and this arc sheet is connected with the clamping supporting leg, therefore can be clamped in wire end as between clamping supporting leg that meets the boundary and the clamped edge.This wire end can be introduced the window from arc sheet one side.
Connect terminal transition position because clamped edge is in, discharge the district so the integral width of conductor rod can allow electric current to flow to from the connection lead that is clamped to clamped edge, thereby can realize low contact resistance to the release district.
In addition, this connection end only has a window, and two connection leads that wherein will be connected in this window are clamped where necessary.Therefore terminal can be connected make narrower, so that it is installed in the installation switchgear that standard module one half width is only arranged.
In an advantageous embodiment of the present invention, can clamp on the clamping supporting leg of reed vertically fluting so that two clampings that connect leads, thereby produced two can be clamped independently of one another next-door neighbour's part reed.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.
According to a particularly advantageous embodiment of the present invention, it is adjacent that described arc sheet and first clamp supporting leg, this first clamps supporting leg and incorporates second portion clamping supporting leg at the curved edge place into, described second portion clamps supporting leg and comes out from first's clamping supporting leg bending, so first and second parts clamp supporting leg each other in the obtuse angle, its opening points to the direction of insertion that connects lead.
The obtuse angle that first and second parts clamp between the supporting leg provides a favourable part: the advantage point of using the reed drive unit be in curved edge near.If be placed on first and second parts clamp curved edge between the supporting leg near, then the set-point of reed drive unit can have bigger distance with the point of rotation of clamping supporting leg at arc sheet place, and need not to make thus obtained maximum end openings to diminish, and need not that the reed drive unit is in and allow to connect the state that lead has bigger cross section.Yet bigger distance means more favourable lever ratio between this set-point and the point of rotation, and therefore makes the user need littler actuating force.So just can solve another problem of the no screw connecting terminal of the previously known in the installation switchgear.This is because in order to introduce the connection lead, utilize drive unit to produce the next crooked supporting leg that clamps of mode that is used to introduce the window that connects lead between the clamped edge of clamped edge that clamps supporting leg and conductor rod usually.If will insert connection lead, and then must make window enough big with big lead cross section.In the terminal according to EP1575130 connected, the application point of reed drive unit must be placed adjacent to each other relatively with the knee-piece that clamps reed.Perhaps, this reed drive unit can be to operate connecting lead.Yet the result can produce the lever ratio that is unfavorable for the operator.In connecting according to the clamping of prior art, the user can be correspondingly bigger in the actuating force that is applied when opening a terminal by nip of pressing the terminal cover part.Clamping connection according to the present invention can reduce this actuating force.

The conductor rod 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.Clamp reed 12 and have support leg 212, this support leg 212 is supported on reed on the bearing edge 118 of conductor rod 102.Can support in the following manner: support leg 212 is curved on its free end has, and support leg 212 is partly sealed bearing edge 118 to reach the purpose of support by bending on this.
It is adjacent that 214 beginnings of arc sheet and first clamp supporting leg 217, and this first's clamping supporting leg 217 becomes second portion in the bending of curved edge 219 places and clamps supporting leg 218, so first's clamping supporting leg 217 and second portion clamp 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.
In the embodiment that terminal shown in Figure 6 connects, on bend free end elongation at the 2nd U supporting leg 222, to form release lever 226.Release lever 226 forwards are connected to the 2nd U supporting leg 222; Itself and latter's near normal ground point to the direction of window 116 and outstanding thereon.
Be equipped with on another curvedly at the free end of release lever 226, another connects lead and can weld or rivet on it.
Yet going up the curved terminal that also can directly be used as in the switchgear connects.
On the whole, the exterior contour that has similar lowercase " b " according to the conductor rod 102 of present embodiment.The connection of conductor rod 102 terminal 112 is supported facing to release lever 226.This has strengthened terminal and has connected 10 mechanical stability.
Can obtain following advantage in addition: between the insertion that connects lead and separation period, act on terminal and is connected the terminal framework that power on 10 can be used as closed system and absorbs, and reduced to act on other element of installation switchgear thus such as the power on encapsulating.
The terminal cover part 22 that the opening 20 of terminal connection space 18 is rotatably connected to packed part 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 the corresponding component that will be similar to tubulose is downloaded to joint pin 232, and 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 points to encapsulation via intermediate 325 and internally is connected with spacer region 338, spacer region 338 also extends with the narrow side 8 in the back side on the direction at back 305 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 354 film hinges that are connected to rotatably 352 of above-mentioned enclosure portion.
This is the partly overlapping at least flat board of parts 356 at the package-side place at its free end and the back side 305.The enclosure portion 354 of back side package-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 305 back that are in the parts 356 at package-side place slide, and guided in the mode that moves abreast with the latter by rocking bar shape guide cavity 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 encapsulation according to the enclosure portion 354 of its closed position of Fig. 6 and spacer region 338.In the position according to Fig. 7, when terminal cover part 22 changed the inside of encapsulation over to, enclosure portion 354 and spacer region 338 formed the obtuse angle, and it is inner that the opening at this obtuse angle points to encapsulation.
During in the start of terminal cover part and around joint pin 232 rotations, enclosure portion 254 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 305 parts 356 back that are positioned at the package-side place move abreast so that the mode of saving the space is approximate.Under rigidly connected situation, as be known in the art, enclosure portion 354 can change the inside of encapsulation over to and stop up its motion path, the feasible functional device or the assembly that wherein can't hold switchgear again.
The connection lead is guided through the end openings 26 in the terminal cover part 22, and after leaving tubular opening 28, runs into the clamping supporting leg 216 that clamps reed 312.
If connecting lead is rigid wire, the clamping supporting leg 216 that then clamps reed 312 can only utilize and connect lead and open from clamped edge 120 extruding, arrives following degree: make that connecting lead can insert and be clamped in the free end and the window 116 between the clamped edge 120 that clamps 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 tubulose recess 28, be loaded with the front end 30 that points to clamping supporting leg 216 at intermediate 325 places, it is as the reed drive unit.
Owing to clamp the effect of the back stretch 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 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 so that it rotate time carrying clamps the mode that reed opens to curved edge and aim in the cover part.
In an example, first and second parts clamping supporting leg 217 and 218 forms and is about 160 ° angle.Compare with the clamping reed 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.
Scheme as an alternative, the opening action of terminal cover part 22 also can be realized by the radial slot that can buy or crossed grooves 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 (flute profile, cross or spherical notch) of reception.
Although in the example of Fig. 6 and Fig. 7, only show an end openings 26 and a tubulose recess 28, in fact can provide two or more these type of end openings and recess to receive and to be connected a plurality of connection leads in the intermediate 325.The connection lead that all have connected all can be clamped supporting leg 216 clampings by it by public clamping reed.When terminal cover part 22 was driven, all leads that connected were all discharged simultaneously and can be separated simultaneously.
The terminal cover part 22 that has first's body 322, hinge 352 and enclosure portion 354 also can be made up of two kinds of materials with different mechanical attributes.They can be bonded to each other 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 clamping reed 312, and avoids or minimize at least the thorough bending of this composition in this process.
This 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.
The elasticity of enclosure portion 354 also help to make the latter with the back side 305 abreast in rocking bar shape guide cavity 360 when the narrow side 7 in front moves, can bend to himself to a certain extent, thereby can be placed on the positive narrow side 305 easier and narrowlyer.
On the whole, this makes enclosure portion 354 can make guiding more closely in 305 places overleaf, thereby saves bigger space during the rotation of terminal cover part 22.
