A point in the end remembers that armature component 13 of the present invention can fix or lays via rotor mounting 30.Rotor mounting 30 can be related to relay casing 48 (promptly being fixed on the relay casing 48) and come axial restraint rotor clamp 29, and the rotor mounting 30 that is fixed holds, the upper end of fixed rotor clamp 29 is so that relay user valid function under the situation that does not have relay cover 49 electromagnetic relay device 10 of the present invention.Thereby rotor mounting 30 or be used to bridge chair frame or member that rotor assembly or axle assemble be installed can be described as providing certain member that can open type operation electromagnetic relay device 10.Can consider that for example under certain situation, the relay-set of uncovered has certain benefit.For example, the passive relay device possibly observed in test process more easily.In any case, can consider to be fixed in relay casing 48 to armature component 13 through different modes, rotor mounting 30 of the present invention like this makes electromagnetic relay device 10 realize the uncovered operation.

The switch module 14 of this relay-set 10 preferably includes the first switch terminal assembly 31, substantially referring to Fig. 1 to Fig. 4; Second switch Wiring terminal assembly 32 is referring to Fig. 1 to Fig. 3, Fig. 5, Figure 13 and Figure 14; Three spring assemblies 33 are referring to Fig. 1 to Fig. 3, Fig. 5, Fig. 8 to Figure 11, Figure 13 and Figure 14.These figure that mention through observation post can see that the first switch terminal assembly 31 preferably includes first contact button 34 and first switch as 11 is terminal.And the second switch that second switch Wiring terminal assembly 32 preferably includes as 11 is terminal.

Three spring assemblies 33 preferably include second contact button 37, referring to Fig. 1, Fig. 2, Fig. 9 to Figure 11, Figure 13 and Figure 14; First spring 38, second spring 39 and the 3rd spring 40 can be further referring to Fig. 5, Fig. 8 to Figure 10 and Figure 13.Can see that further first spring 38 preferably includes like first contact 41 and holds the aperture and like the C shape aperture 42 among Fig. 8, add like end fixed offshoot or the elbow 70 among Figure 13 and Figure 14.Notably, preferably to hold aperture 41 concentricity with first contact in a C shape aperture 42.Second spring 39 preferably includes like second contact 43 and holds the aperture and like the C shape fold 44 among Fig. 8.Can see that through observing Fig. 8 a C shape fold 44 has first curvature radius.The 3rd spring 40 preferably include as the 3rd contact 45 hold the aperture, like the 2nd C shape aperture 46 and the 2nd C shape fold as 47.

Can see that further the 2nd C shape aperture 46 is preferably concentricity with support aperture 45, the 3rd contact, the 2nd C shape fold 47 has second radius of curvature, and this second radius of curvature is bigger than (a C shape fold 44) radius of curvature on size is liked.Second spring 39 is clipped in the middle of first spring 38 and the 3rd spring 40 via holding or pass second contact button 37 that the contact holds aperture 41,43 and 45.The one C shape fold 44 is in the 2nd C shape fold 47, and is and concentricity with its (about fold axis).In the same way or side by side, be closely adjacent to each other on first contact button 34 and second contact button 37 or the contact space, big volume description is seen Fig. 1, Fig. 2, Fig. 9 and Figure 10.In the preferred embodiment, three spring assemblies 33 are offset to the break contacts position between first and second switches terminal 11, and are connected on the armature arm 22 (side), and this point is Fig. 9 and shown in Figure 10 the clearest perhaps.

Expect that a C shape aperture 42, the 2nd C shape aperture 46 and end fixed offshoot or elbow 70 can provide certain member strengthening the excess of stroke well, thereby increase pressing of first contact button 34 and second contact button 37 centres.In this respect, the reader can further remove to see Fig. 9 and Figure 10.Contrast considers that these figure that mention can see, the terminals side 53 of spring assembly 33 possibly crossed the flat of spring assembly, the handle 51 of this part next-door neighbour contact button 37 by driving.Like this, form the folding spring section of button with the handle of contact button 37 51 next-door neighbours''s (and radially adjoining) spring assembly flat, as 52 among Fig. 8 and Figure 11.Observe Fig. 8 and Figure 11 and can find out that button foldable portion 52 is stacked on the contact button 37, and the terminals side 53 of spring assembly 33 flexibly is out of shape as 50, thereby realize the described excess of stroke.

In other words, the material (preferably copper) of spring element that has C shape aperture is like the end in the C shape aperture 50 among Fig. 8 more easily, more can flexiblely be out of shape.Notably; The strain of adjacent end 50 does not cause basic material lattice to produce tangible embrittlement (promptly can not transmit undesirable lattice dislocation significantly); Thereby the member of the C shape aperture structure of three spring assemblies and characteristic the enhancing excess of stroke that a kind of stalwartness is provided, and then can in the middle of

contact button

34 and 37, increase certain pressure to improve conductive contact therebetween.End fixed offshoot or elbow 70 further provide a kind of member that strengthens the excess of stroke, can increase to press, and alleviate the contact bounce of

contact

34 and 37.

Therefore, through the control of C shape aperture and/or the enhancing excess of stroke, the conductivity of contact button 34 to 37 is improved, and is shown in figure 10 substantially.The contact that expection strengthens is that the wiping that improves the contact provides certain member with the conductivity that is obtained, thereby the wiping of this contact or cleaning element further become possibility because of the excess of stroke that strengthens.In this respect, expect that relay-set 10 of the present invention has inherent self-cleaning function, this is that accomplish in C shape aperture 42 and 46.In addition; Expection C shape aperture 42 and 46 (with offshoot or elbow 70) can provide certain member to alleviate contact bounce; Perhaps suppress the contact vibration in the middle of

contact button

34 and 37, this vibration occurs in from open-circuit condition or open switch position when (as shown in Figure 1 substantially) switches to closed circuit state or closed switch position (as shown in Figure 2 substantially).

Can be readily appreciated that through observing Figure 12 magnetic core or yoke end 20 are being held by rotor sheet 25 and rotor carriage 26 looselys, and armature rotating shaft 101 and terminal 20 coplanes of yoke, rotating shaft 101 runs through rotor clamp 29 (in Figure 20, not specifically illustrating).Should understand easily, conductive coil 15 received currents, thereby produce magnetic field, can be further referring to vector among Figure 12 102.Can find out that through observing this figure yoke end 20 is run through via rotor assembly (mainly by rotor carriage 26,

rotor magnet

23 and 25 definition of rotor sheet) in magnetic field 102, thereby the torque of magnetic field induction makes armature or bridge around 101 rotations of armature rotating shaft.

Therefore; Rotor carriage 26 moves the position of magnetizing exciter arm 22 point-blank, and this magnetizing exciter arm 22 that is moved the position orders about three spring assemblies 33 and moves to spring driven closed circuit position (as shown in Figure 2 substantially) from the open-circuit position (as shown in Figure 1 substantially) that the spring of first-selection is setovered.Material structure of relay assembly 10 (believing in those skilled in the art's the scope understood) and closed circuit position can let basically the electric current of 120 peaces via first contact button 34, second contact button 37 and switch terminal 11 through switch module 14.When coil block 12 temporary no currents and magnetic field when being able to effectively eliminate, return spring 28 can strengthen the recurrence of three spring assemblies 33 to the spring biasing open-circuit position of first-selection, and is shown in figure 11 substantially.The situation of electric current because possibly break down; So electromagnetic relay 10 preferably considers to comprise the member of certain acquiescence circuit closing contact again, the circuit closing contact member of this acquiescence is forced first contact button 34 and second contact button, 37 closures during described fault current or short circuit current situation occurring.In this respect, the path of following, expection Lorentz electric current or magnetic field is generally shown in the vector arrow 102 among Figure 12.

Can further contemplate that electromagnetic relay of the present invention can comprise that certain member is given tacit consent to it in based on the threshold current state of terminals be the break contacts positions.In this respect, traditional electromagnetic theory shows that the electric charge carrier generation of flowing and the flow direction of charge carrier be the magnetic field of adjacency radially.The reader can see Figure 15 like this, and shown in Figure 15 is the diagram of the threshold current path as 71, and wherein electric current passes

relay wiring end

31 and 32 via contact button 34 and 37.Because the electric charge carrier electric current flows according to path 71, the magnetic force vector of expression comes from terminals as 103.Reach after certain threshold value amperage, interface connection end 31 that is produced and 32 magnetic field will interact with the rotor magnet 23 in permanent magnet or the rotatable armature component 13.Magnet 23 has interior magnetic field, and shown in vector arrow 104, outside this magnetic fields point, its intensity size is littler than the intensity at vector arrow 103 places.Indicated 104 and 103 intensity difference causes that rotatable armature component 13 is to the break contacts rotated position, shown in the diagram of Figure 15.This function can be measured through the size of magnet 23 and the distance of intensity and armature and fixed contact.

Though above-mentioned explanation comprises very big certainty, this certainty should not be construed as scope limit of the present invention, and should be interpreted as illustration of the present invention.For example, the present invention is appreciated that to main explanation or discloses a kind of electric current that can make and pass through the terminal electromagnetic relay device of switch that this electromagnetic relay device comprises coil block, axle assemble and switch module.Coil block comprises coil, coil axes and C shape magnetic core.Coil is wrapped on the coil axes 100, and coil axes 100 runs through magnetic core, as among Figure 12 60.Magnetic core 60 comprises magnetic core end 20, and in fact magnetic core terminal 20 is parallel to coil axes 100.

Axle assemble comprises that axle assemble comprises like the rotating shaft 101, like bridge 61 among Figure 12 and Figure 15 and the switch magnetizing exciter assembly as 22.Bridge 61 comprises intermediate field path 63 (promptly relatively near the path of magnetic core 60), path, field, side 64 (promptly relatively away from the path of magnetic core 60) and axially spaced transverse path 65, transverse path 65 in the intermediate field path 63 with path, field, side 64 in the middle of guiding as 102.Magnetizing exciter arm 22 cooperates with path, side 64, and extends (not shown in Figure 12) away from it.Magnetic core terminal 20 preferably with rotating shaft 101 coplanes, and obtain the support of intermediate path 63 and path, side 64 mid portions.

Expection transverse path 65 provides certain steering component, can make magnetic field 102 relative coil axess 101 laterally turn to and produce the magnetic induction torque, this magnetic induction torque actuated switch magnetizing exciter assembly 22.Described steering component can further be regarded as and comprise certain dividing member (having two like the opposite path of axle 66 among Figure 12), can produce the magnetic couple relevant with the magnetic induction torque.

Cooperate the switch module as 14 to cooperate magnetizing exciter arm 22 especially especially like the switch module 14, magnetizing exciter arm 22 is the connector in the middle of bridge 61 and the switch module 14 in essence.The function of coil is the magnetic field that produces or conduct vector representation as 102.Axle assemble 61 is passed via magnetic core terminal 20 in magnetic field 102, thereby produces the rotation of bridge around rotating shaft 101 through the magnetic induction torque.The position of magnetizing exciter arm 22 is moved in the rotation of bridge, and the magnetizing exciter arm 22 of displacement is on-off switch assembly 14 physically.The easiest understanding in this area, closed switch module 14 allows electric current to pass through wherein.
