Abstract
The present invention relates to a fast-opening magnetic system, which is mainly installed on a multi-range meter requiring overcurrent or overvoltage protection. The armature support is composed of a U-shaped spring piece 5 and a box-shaped bearing 7 sleeved on one arm of the pole shoe 1 of the magnetic system, and the connection of the two arms of the spring piece 5 and the armature bearing 7 is realized in such a way that a fixed point 11 of the spring piece 5 and the armature bearing 7 and a tilting point of the movable armature 4 on a bearing edge 9 of the armature bearing 7 are directly arranged on the arm of the pole shoe 1.
Description
The present invention relates to the magnetic system in order to quick disconnection, this system has " U " shape pole shoe, moving armature and the armature that the cross section is a rectangle and supports.
Known a kind of magnetic system is seen the DE-PS2029607 patent, and this magnetic system that is used for relay in the plastic casing that is contained in has the moving armature that band spring leaf shape armature supports.Spring leaf is fixed on the bobbin of magnetic system, connects with the member that suspends of a corresponding extension.Therefore armature can vertically move, and causes the bigger wearing and tearing of generation on the sharp edge of the rear portion of corresponding pole shoe the first arm.Because the bobbin that is contained on pole shoe second arm becomes flexible to a certain extent, so also not really stable on size relationship.Extension spring has important function on cooperatively interacting with spring leaf, and the action of moving armature also played considerable effect, but extension spring be with base plate on fix perpendicular to the circle ring of axle of spring and to be connected, so also suitable difficulty of the installation of extension spring.
Another kind of known magnetic system is seen the DE-PS2000138 patent, and its armature supports and also is made of spring leaf, and this spring leaf is fixed on the pole shoe on the one hand, is connected with moving armature on the other hand.Helical spring is used for disconnecting to vert moving armature magnetic circuit.Moving armature and spring leaf and still quite complicated owing to structural reason with the helical spring acting in conjunction, therefore required expense is higher.
Another known quick disconnection magnetic system is seen the DE-OS3643510 patent, and its armature supports and also is made of spring leaf, is being provided with the case shape long element that can be sleeved on the independent pole shoe on the spring leaf.The sweep of spring leaf is connected with moving armature end overhanging above independent pole shoe.The manufacturing expense of this spring leaf is higher, and requires complicated flector.
Above-mentioned these magnetic systems are very sensitive to the reacting condition of magnetic circuit, and particularly the reacting condition of gap value is very sensitive between pole shoe and the moving armature.Gap length between interior two parts of magnetic circuit depends on the surface of contact site and existing particle between this surface.The variation of two parts relative positions of magnetic circuit also can cause the variation in space, and this depends on various supporting point.
The objective of the invention is to further improve above-mentioned this magnetic system, and guarantee after higher operational cycle number, to reach stable as far as possible response value.At first should improve armature bearing for this reason.Make required parts be convenient to make in addition, be convenient to install, and can use simple mounting technique to guarantee installing and locating accurately.
Purpose of the present invention can solve by architectural features more of the present invention, that is:
Armature supports by " U " shape spring leaf and the box-shaped armature that can be sleeved on the pole shoe the first arm and supports formation, armature bearing and a support are linked to be an integral body, two arms of spring leaf contactlessly extend through and are separately fixed on the support from the narrow side of armature bearing, the tie point of spring leaf is located immediately on the support, and on the support edge of the wide side that a little is positioned at armature bearing of verting of moving armature.
The spring leaf of being made by spring steel band is by support and be connected with armature bearing that plastics are made.
Spring leaf is connected with moving armature on the one hand, is connected with spot welding with armature bearing on the other hand.
Rank rank bearing-surface has the crosspiece that is used for locating to a side of moving armature on pole shoe, the distance between two crosspieces should make moving armature be positioned under closure state on two polar arms of pole shoe, can move between crosspiece when disconnecting and does not contact mutually with polar arm.
Two arms of spring leaf are not in contact with it in the narrow both sides process of armature bearing, just are connected with support, and support then fuses with armature bearing.
The invention has the advantages that: spring leaf is parts that are easy to make, and almost is specifically designed to the guiding of armature, makes to have only longitudinally that masterpiece is used on the armature.
One embodiment of the present of invention are as shown below, and existing details are as follows:
Fig. 1 is the perspective view that disconnects magnetic system fast.
The perspective view that Fig. 2 supports for the magnetic system moving armature.
As shown in Figure 1, the critical piece of magnetic system is a pole shoe 1, by the small gap cross section its first arm is shown, and its second arm does not give and illustrating, and is with the bobbin 2 of band winding 3 on this second arm.By moving armature 4 closed magnetic paths, moving armature under static state is positioned on the both arms of pole shoe." U " shape spring leaf 5 has two arms as the support of moving armature 4, and two arm ends 6 are connected with box-shaped armature bearing 7.Armature is supported on following of the constant situation of its load direction needs less initial stress just can be sleeved on the first arm of pole shoe 1.At this moment, shift phenomenon can not take place.Therefore, can guarantee that pole shoe 1 can both repeat to contact after each load cycle with moving armature 4 exactly on same position, magnetic circuit also repeatedly reaches same value all the time.
Because the parts of magnetic circuit are made of soft magnet material, its poor mechanical properties therefore for a reliable magnetic system, requires to have a good armature bearing.For this reason, should making itself and moving armature 4 under the magnetic circuit closed situation between, the shape at armature bearing 7 upper support edges 9 forms a very little slit.Moving armature 4 can just arrive support edge 9 by short stroke very when verting, because whole armature bearing 7 is made of plastics, so support edge 9 has good bearing performance, can only produce very limited wearing and tearing when slip.
In addition, armature bearing 7 has usefulness so that two crosspieces that armature bearing 7 positions in a side of narrow limit facing movament armature 4 on pole shoe 1 the first arm.Therefore, can guarantee that support edge 9 carries out very accurate in locating by this crosspiece with respect to the pole-face of refined boots 1 the first arm.Like this, in made magnetic system, just can always guarantee the optimum position of support edge 9.Can produce bigger wearing and tearing when between the parts of making by soft magnetic material, taking place to slide,, magnetic characteristic and starting value are changed if in the space, produced wearing and tearing.Just almost completely prevented the mutual slip between the metal by above-mentioned supporting.
Figure 2 shows that each parts that armature supports, spring leaf 5 is " U " substantially, and its two arm 6 is connected with armature bearing 7 by support 10.Support for the armature that is made of spring leaf 5 and armature bearing 7, what relate to is connectivity problem between metal and the plastics.Support 10 is used for connecting this two parts, for this reason, and can be at fixing point 11 enterprising spot weldings.Two crosspieces 8 of armature bearing 7 are used for making armature to be supported on the first arm of pole shoe 1 accurately location.The fulcrum that support edge 9 verts with spring leaf fixed thereon 5 as moving armature 4 has conclusive effect.Moving armature 4 vert a little and fixing point 11 all directly places on the pole shoe the first arm, therefore, can guarantee the lasting and stable location of 4 pairs of pole shoes 1 of moving armature.
