Description
Technical field
The present invention relates to a kind of failure current protection switch or differential current protection switch; it has a handle and a feeler switch; described handle can deflect between an on-position and an open position; so that with described switch connection and disconnection; described feeler switch can be pushed downwards on-position from the open position of described feeler switch; when described feeler switch is in its on-position, the test contact closure, thus connect measuring current.
Background technology
Measuring current is used for the testing equipment function.In the case, measuring current replaces real fault current.
Being used for feeler switch self and being attached thereto the installing space of element of related specifications (for example standard of pertinent regulations creepage distance and electric clearance) defined is extremely limited.The feeler switch of being handled by operating personnel must be arranged in the operating space of failure current protection switch (claim not only FI protection switch) or differential current protection switch (but also claiming the DI protection switch).Taking up room is in the standard device of a horizontal pitch, and the area of operating space is 45mm * 18mm.In this operating space, except that feeler switch, also must arrange handle, the arrangement that should be label in addition keeps corresponding space.The effect of label is the performance data that failure current protection switch or differential current protection switch are provided for operating personnel.
For staying big as far as possible space to label, people may tend to feeler switch near handle arrangements.But so just might be when control crank, because of feeler switch is pressed in carelessness.Should avoid this class misoperation.
Summary of the invention
The objective of the invention is the failure current protection switch or the differential current protection switch of the described type of introductory song are improved, make that the space in the operating space obtains optimum utilization as far as possible.
This purpose is reached by a kind of failure current protection switch or differential current protection switch with the described feature of claim 1.
In view of the above, the arrangement of feeler switch is, when handle was in its open position, feeler switch was covered (thereby can not handle) to small part by handle for operating personnel.
The present invention is based on a kind of like this understanding, that is: it originally is exactly only just meaningful when handle is in on-position testing by feeler switch.Therefore, when being in open position, handle occurs in the situation on the feeler switch, and unimportant for the rational Application of feeler switch.In the direct deflecting region that feeler switch is arranged in handle open position zone inner handle, promptly feeler switch can obtain the space that is used to settle label not away from handle arrangements in the operating space of failure current protection switch or differential current protection switch.When handle was in open position, feeler switch can not handled, and this point can't have a negative impact, wherein, it can be the unmanageable reason of feeler switch place that feeler switch is partly covered, and in addition, other mechanisms also might cause the not navigability of feeler switch.
In a lot of traditional failure current protection switch or differential current protection switch, when feeler switch was subjected to handling, handle can spring back to its open position from its on-position.For avoiding this situation; and then be subjected to the obstruction or the injury of resilience handle when avoiding operating personnel feeler switch to be operated by finger presses; protection switch preferably has a blocking element that can move with feeler switch; when feeler switch is depressed to its on-position; this blocking element is with the handle locking; thereby avoid handle to return back to its open position from its on-position (when pressing feeler switch, handle must be in this position).
For making protection switch further have cramped construction; also can be set as follows: when handle is in its open position; handle is pressed this feeler switch towards the on-position direction of feeler switch, when handle is in its on-position, by a spring feeler switch is shifted onto on the open position of this feeler switch.
That is to say that when the needs feeler switch had navigability, feeler switch protruded slightly, this can simplify the operation.When handle is in its open position, when promptly there is no need feeler switch handled, feeler switch just is hidden in the following or next door of handle, to reach the purpose of saving the space.
The interaction that handle and feeler switch may carry out can realize by the mechanism of following compact conformation: handle has a rotating roller.Be built with a space in the roller.An element that is attached on the feeler switch passes from this space, is built with a peg on the described element, and described peg embeds in the roller.By the described element of attaching, feeler switch truly can be arranged in the roller next door, corresponding mechanism then is arranged in this space by described associated element.Be embedded in a peg in the roller and an interior contoured surface acting in conjunction of this roller.During roller turn, contoured surface is had an effect to peg in this, and then associated element and feeler switch are had an effect, and in case of necessity feeler switch is pressed.
Peg can advantageously play the effect of above-mentioned blocking element simultaneously.In the case, peg can be pressed with feeler switch, through a thickening part of a roller wall.Owing to there is this thickening part, the roller wall just can't rotate around peg again.The inboard of roller wall constitutes above-mentioned interior contoured surface.
As using replenishing or replacement scheme of this scheme of peg, handle also can interact by a breach and feeler switch.This breach should be designed to the corresponding profile of a profile of feeler switch.In the case, when handle was in open position, handle can partly surround feeler switch by this breach, and the active force that overcomes spring makes feeler switch keep the state that is pressed.
When handle is in its on-position, shift feeler switch onto open position by spring, providing aspect the spring with this effect, there are two kinds of preferred implementations:
One can be designed for described spring handle is pushed back extension on the torsionspring of open position.This torsionspring normally just exists originally, and is bearing in the shell by one first clavate extension.Under the situation that this first clavate extension self obtains continuing by one second clavate extension (specific perpendicular to described the first clavate extension extend) again, this second extension plays the effect of spring equally owing to be bearing in the shell.So just need not provides two outer casing supporting mechanisms separated from one another for feeler switch spring and torsionspring.
According to a kind of substituting execution mode, described spring comprises a contact point, when feeler switch is pushed downwards its on-position, described point pressure is on a corresponding contact site, thereby make the test contact closure, wherein, the measuring current of the Jie Tonging spring of can flowing through therefrom.It is difunctional to adopt the spring of this execution mode to have, and promptly provides elastic force on the one hand, is on the other hand to replace an independent contact element that generally must exist.Can reduce the sum of necessary assembly whereby, thereby save cost.

Embodiment
Comprise an operating space 12 with 10 failure current protection switch of representing on the whole.Be built with a handle 14 on this operating space, handle 14 can deflection between an on-position (seeing " I ") shown in Figure 1 and an open position (seeing " O ").In addition, 12 also can touch a feeler switch 16 from the operating space.Handle 14 is structured on the roller 18, can know from Fig. 1 and see, feeler switch 16 directly is arranged in this roller 18 next doors.If handle is in its open position (referring to " O " among Fig. 1 or see Fig. 5 and Fig. 6 in addition), feeler switch 16 is just covered by handle 14 for operating personnel fully.This point does not belong to rough sledding because feeler switch 16 should just can be touched when handle 14 is in on-position shown in Figure 1, and situation also the way it goes.The advantage that feeler switch 16 directly is arranged in roller 18 these arrangements of next door is, can reserve king-sized space for label (not illustrating among Fig. 1) on operating space 12, can be the performance data that operating personnel provide described failure current protection switch whereby.
As being used to show that Fig. 2 of failure current protection switch 10 inner cases is extremely shown in Figure 6, the structure of failure current protection switch 10 is also compact especially.This point mainly realizes by the space on the roller 20.Element 22 on feeler switch 16 that is attached to truly is embedded in this space 20.Be fixed with (metal) bridge 24 on the associated element 22.When feeler switch 16 and associated element 22 were pressed in the lump, bridge 24 was pressed together, thereby with first contact 26 and 28 cross-over connections of second contact, so just can connect circuit.Can connect measuring current whereby, when testing, this measuring current can replace fault current.It is the same that accompanying drawing is not made the circuit of illustrated remaining circuit arrangement and traditional failure current protection switch.Provide can with the situation in the space 20 of associated element 22 engagement under, bridge 24 is not below (if the tight 20 that is positioned at feeler switch 16, then bridge 24 must be positioned at feeler switch 16 belows), but be arranged in the below of roller 18, can reach the purpose of saving the space whereby.
When handle was in on-position, feeler switch should arrive a position of rest, and pushed this position of rest by a spring.
Failure current protection switch 10 has had an operational torsionspring 30, and the task of this torsionspring is that pair of rollers 18 applies elastic force, and then handle 14 is applied elastic force, and handle 14 1 leaves on-position, just it is pushed open position.Described torsionspring comprises one first clavate extension 32, and this extension is bearing in (Fig. 2 illustrates) in the shell.First extension 32 is the same with the extension of conventional torsionspring.But different with conventional torsionspring is, first extension 32 transit to one vertical with it, to second extension 34 of other direction bendings.On torsionspring 30, produce a L shaped element thus.This second extension 34 is bearing in the cavity 36 of feeler switch 16.Described cavity (" front " from Fig. 2) is a cuboid, is funnel-form and extends (seeing it is to extend " backward " from Fig. 2).
If what relate to is traditional failure current protection switch, when feeler switch was pressed, handle can forced back towards its open position.This point is disadvantageous for the present invention, because when pressing feeler switch 16, handle 14 may make operating personnel's finger injuries.For avoiding handle 14 injury operating personnel, be furnished with peg 38 on the associated element 22.Associated element 22 is embedded in the space 20, and 38 of pegs are stuck in below the wall 40 of roller 18.Wall 40 is gone up and is thickeied in its a position 42 (being its end in the present embodiment).When key 16 was pressed, the thickening position 42 of wall 40 can not hinder peg 38 to move downward, referring to Fig. 3 and Fig. 4.But thickening part 42 can prevent roller 18 and rotate, because (feeler switch 16 is pressed the) when counterclockwise rotating, and thickening part 42 can be hit on peg 38, thereby prevents that handle 14 from leaving on-position from state shown in Figure 4 when roller 18.
Peg 38 also advantageously has other functions.When handle 14 deflected to its open position, feeler switch 16 was not to be pressed by operating personnel, because handle 14 has just in time hindered operating personnel feeler switch 16 was operated.If but when handle 14 arrived its open position, feeler switch 16 was in depressed position, then is favourable, so just need not provides too much space for feeler switch.In the case, when roller 18 rotated, associated element 22 and feeler switch 16 just were pressed by peg 38: free space 44 that is made of wall 40 ends at one of roller 18 radially support arm 46.Thus the interior contoured surface of the roller of Xing Chenging (the interior profile of wall 40 and support arm 46 points to the profiles of pegs 38) make peg 38 roller 18 from state shown in Figure 3 when counterclockwise rotating, the initial effect that is not subjected to power, but rest in the free space 44.At last, radially support arm 46 contacts with peg 38, and orders about peg move downward therewith in roller 18 rotating process.In this way associated element 22 and feeler switch 16 are pressed together, referring to Fig. 5 and Fig. 6.In the present embodiment, when handle 14 is in its open position, just press feeler switch 16, but not fully feeler switch is pressed to its on-position towards the on-position direction of feeler switch, in the case, bridge 24 not cross-over connection contacts 26 and 28.According to other circuit arrangement (accompanying drawing illustrates) in the failure current protection switch, may have the electric current bridge 24 of flowing through in addition.But this point is not to be necessary.If all electric currents all are suppressed owing to handle 14 is in its open position, also can be with feeler switch 16 fully by to its on-position.But in the present embodiment, feeler switch 16 has been enough to create enough big space for the handle 14 that arrives open position towards the degree of displacement of its on-position direction.
Fig. 7 and Fig. 8 show be failure current protection switch 10 of the present invention ' second execution mode.Structure shown here and failure current protection switch 10 basically identicals (comparison diagram 2 and Fig. 7).Handle 14 is structured on the roller 18.This roller has a space 20, feeler switch 16 ' an associated element 22 ' be structured in this space.This associated element 22 ' on a peg 38 is installed, the remainder structure of this roller 18 is also consistent with the roller of failure current protection switch 10, therefore, the mode that this roller can be above illustrated and peg 38 interacts.
Failure current protection switch 10 ' be on the one hand with the difference of failure current protection switch 10, feeler switch 16 ' be not to be structured on the edge of failure current protection switch shell, an additional shell wall 48 of failure current protection switch 10 ' have with flushing.
On the other hand, feeler switch 16 ' the way of contact and its mode that applies elastic force also is different from failure current protection switch 10.Aspect feeler switch 16 ' apply elastic force, use be from having elastic component 50, but not torsionspring, this flexible member be resisted against associated element 22 ' on.Pressing 16 ' time of feeler switch needs the no longer the sort of mode closure by bridge 24 of closed contact, but spring 50 self is promptly charged, subsequently conduction.Press 16 ' time of feeler switch, a contact point of spring 50 (in Fig. 7 and Fig. 8 all by associated element 22 ' cover) is pressed on the contact-making surface 52 as corresponding contact site, thereby circuit and measuring current are connected.Why favourable reason is that spring 50 has been carried out dual utilization to this execution mode.In addition, spring 50 is tested person key 16 ' defined the influence of this fact by shell wall 48 not, also can be used in the variant of first execution mode.
Failure current protection switch 10 ' also have the 3rd feature that it is different from failure current protection switch 10: be provided with a space 54 in the transition region between handle 14 upper handles 14 and roller 18.When handle 14 arrives its open positions, push 16 ' time of feeler switch downwards, space 54 can be with feeler switch 16 ' encirclement.56 pairs of feeler switchs 16 of wall above in Fig. 8, being positioned at of space 54 ' the surface directly have an effect.Under situation shown in Figure 8, feeler switch 16 ' pressed fully, thus the contact that spring 50 and contact-making surface 52 are constituted is kept closed.This failure current protection switch 10 ' in realize that by remaining circuit arrangement this part circuit arrangement can prevent that handle 14 from having electric current to flow when being in its open position.In case of necessity, also can take not allow feeler switch 16 ' arrive the fully measure of its on-position herein.
Above-mentioned two kinds of execution modes of the present invention; be failure current protection switch 10 (Fig. 1 to Fig. 6) and failure current protection switch 10 ' (Fig. 7 and Fig. 8); all has following advantage; promptly by to feeler switch 16 or 16 ' carry out flexible positioning; can realize cramped construction, consult especially the space 20 of pair of rollers 18 above and associated element 22 or 22 ' explanation.Can (referring to the operating space among Fig. 1 12) upward obtain king-sized space in the operating space whereby for the label that may settle.
