Composition and actually allow to change relay impedance be coil, if coil the number of turn with Conductor part aspect difference is then hence in so that a class relay is different from another kind of relay, it is possible to from having The magnitude of 1 Ω of low-impedance relay (activates size in major part to the more conventional value of about 40 Ω Select under (activation caliber) and sensitivity), and such as 2000 Ω can be up to.
Known operation principle is as follows: differentiator such as occurs in the circuit by differentiator unit protection During sequential affair, the wire of coil produces faradic current, is in this case returned in magnetic by coil The flowing formed in road and the flow combination produced by permanent magnet.The flowing induced by magnet with pass through The electric current formed flow combination occurred in coil is broken initial mechanical balance and blade is pivoted, leaf Sheet is attracted to contact the end polar surface of armature.The motion of blade makes mechanical component move, such as bar The lock being positioned near electromagnetic actuator of differentiator product can be unlocked, thus described bar can act on actuator On.
Coil is unique difference between dissimilar relay, during thus it is formed in relay assembling Need selected parts.In industry assembles chain, in most of the cases for assembling the step of coil Carrying out in early days, the coil selected from different available line circle inventories for product the most during assembly is the One stage installed.
In order to preferably meet the market demand, then need to manufacture different types of relay so that they Always meet stock's needs.This is unadvisable manufacturing or depositing aspect, many involved by this operation Adverse influence.
Summary of the invention
In order to solve this problem, and simplify the course of industrialization of described relay, according to the present invention's simultaneously Apparatus and method can realize the unitized manufacture of whole actuator in addition to the coil, and coil is according to needing Ask and add at the end of assembling product in the way of system in good time.
In other words, according to the electromagnetic actuator of the present invention, its substantially comprise with fixed magnetic armature and The magnetic circuit that blade is constituted, described blade is resisted spring and is moved and mechanical actuation component can be made to transport Dynamic；With include induction coil, it is positioned at around armature branch, and its assembly is inserted into housing, machine Tool component highlights from housing, it is characterised in that housing includes the hole being positioned within magnetic circuit, the most once Housing closes, and coil is wound.
The hole defined by enclosure interior face is positioned near outside at least one of described housing, coil with Back wall is wound around around the branch of housing, and this branch includes a part for magnetic anchor and by hole and housing Proximal lateral is separately.
Hole is virtually completely defined by housing, and described housing is of completely closed, in having on the periphery of hole Face, portion.
According to a possible configuration, this hole can be U-shaped, and it is formed at the outside of housing, and a bar Door bolt is put in this hole near described side, and described bar is formed in the housing and around the part of magnetic anchor. In this case, the part forming bar of housing is thinner than housing remainder, and relative to described shell Rearward, and it is for being wound around base portion of very normality (natural) of winding in the neighbouring outside of body.
According to a kind of feasible configurations, in any case coil can be wrapped on support member, described support member includes Cylindrical sleeve and at least two end flange, this sleeve is around bar.
In order to enable to be positioned on bar by coil, coil supports can be with two parts manufactures, said two portion Part can assemble along the direction being parallel to sleeve axis.They have been placed between the sleeve of two half at bar The most secured to one another.
Alternatively, coil supports can be fabricated to the single parts of flexible elastic material, and it is provided with formation Radial gap in flange and sleeve.In this case, gap flexibly broadens to allow bar pass through, The elastic connecting of material gets off to make gap Guan Bi and capture bar.
In order to the coil supports imparting rotation for being wound around coil, the periphery of at least one flange can carry There is tooth.Described support member then can rotate by there being the outer driving wheel of tooth.
But, before any rotation, it is important that the end of the wire of coil supports will be wound into Fastening.According to a feasible configurations, one of them end of sleeve can be provided to by two neighbouring flanges This end.Wire is wound around a few subsequently, and idiomorphism is tight by the extruding (jam) between two flanges Being affixed to support member, said two flange is very close to each other.
Alternatively, one in two ends of sleeve can be stretched out from flange, and the axial dimension of coil is basic The upper axial dimension equal to bar.In this case, two adjacent flange of foregoing solutions are actually Being replaced by the inwall in flange and hole, foregoing same principle is followed in fastening, because the jag of sleeve Portion arranges the shortest and this wall is therefore very close to flange.
According to another possible replacing structure, it is hook-shaped that the exterior face of flange could be arranged to have at least one Thing, two uncinuses preferably positioned relative to the axisymmetrical of support member, and two uncinus weeks Enclose and be first wound around a few circle and can realize foregoing identical result: secure wires and there is no restrictive machinery behaviour Make.
Finally, still for realizing identical result, at least one flange may be included in the metal on its exterior face and dashes forward Go out portion (pellet).The latter is used subsequently to weld the end of wire to be wound.
The invention still further relates to for the method manufacturing the electromagnetic actuator with aforementioned features, it mainly includes Following step:
-assemble armature, blade, spring and mechanical component in the housing；
