Abstract
The invention provides a relay armature and a movable spring leaf assembly. The armature and a movable spring leaf are metal pieces, and a plastic connecting piece is arranged between the armature and the movable spring leaf. When the plastic connecting piece undergoes injection molding, the armature, the movable spring leaf and the plastic connecting piece undergo direct pressure injection to be of an integrated structure, and an insulator is arranged between the armature and the movable spring leaf and forms an integrated structure between the armature and the movable spring leaf in the injection molding process. The movable spring leaf assembly has the advantages of simplifying product assembly and improving product quality. For a relay, due to the fact that a certain electrical insulation strength is guaranteed between the movable spring leaf and the armature and the movable spring leaf moves frequently under the drive of the armature, the movable spring leaf and the armature are easily damaged parts of the relay. Accordingly, after the technology is used, the relay quality is greatly improved, and the service life of the relay is prolonged.
Description
Technical field
The present invention relates to a kind of armature of relay and movable contact spring assembly.
Background technology
In a lot of miniature intermediate relays, all adopt the armature upset directly to drive the structure of movable contact spring (contact).At present general adopt after the movable contact spring injection mo(u)lding carries out with armature that heat fuses or both adopt the metal rivet riveted joint.Fuse with armature heat after the movable contact spring injection mo(u)lding and be connected, may produce undercapacity when fusing, and production process equipment is complicated; The metal rivet riveted joint can satisfy bond strength, but part is various, and production procedure is complicated, and produces easily the problem of electric insulation undercapacity.
Summary of the invention
The invention provides a kind of armature of relay and movable contact spring assembly, forming of this assembly adopts two inserts technology that the two is formed integrative-structure in manufacture process, need not the later stage connection.The beneficial effect that this assembly brings is that production procedure is simple, and structural strength is high, Improving The Quality of Products.For relay, because the frequent motion of movable contact spring under armature drives, cause movable contact spring and armature to be the consumable accessory of relay, therefore, after the technique use, have greatly improved for the quality of relay, prolong its useful life.
For solving the above technical problem, the invention provides following technical scheme: a kind of armature of relay and movable contact spring assembly, armature and movable contact spring are metalwork, and armature and movable contact spring two sides are provided with plastic fastening, and the plastic fastening inboard has bag along the structure of movable contact spring and armature; Be provided with insulator between armature and the movable contact spring; When the injection-moulded plastic connector, utilize and make good mould, armature, movable contact spring and plastic fastening and the direct pressure injection of insulator are structure as a whole.
Further, described armature bottom margin place is provided with bound edge, and bound edge extends to the side of armature, until plastic fastening, bound edge and plastic fastening are also for utilizing the mould extruding to form integral structure in injection moulding process.
Further, described bound edge is symmetricly set on the both sides of armature.
Further, described insulator bottom has two plugs, and plug matches with the ironing surface hole of rank, and core rod end volume change senior general holds in the mouth the shutoff of ironing surface hole in injection moulding process.
This armature of relay that the present invention relates to and movable contact spring assembly, adopt two inserts technology, make corresponding mould, when injection moulding, armature and movable contact spring directly are integral with plastic fastening and insulator pressure injection, insulator also is between plastics, for fully guaranteeing both bonding strengths, armature has also been adopted bound edge, and between forms certain thickness plastic insulating layer, to guarantee dielectric strength.
Description of drawings
Fig. 1 is the armature of relay of the present invention and movable contact spring assembly assumption diagram;
Embodiment
As shown in Figure 1, armature 1 is metalwork with movable contact spring 2, and armature and movable contact spring edge are provided with plastic fastening 3, when injection-moulded plastic connector 3, armature 1, movable contact spring 2 is structure as a whole with plastic fastening 3 direct pressure injections; Be provided with insulator 4 between armature 1 and the movable contact spring 2, insulator 4 is in the injection moulding process and armature 1 and 2 formation of movable contact spring integrative-structure, and as shown in Figure 1, plastic fastening 3 is structure as a whole with insulator 4, is insulator and also is plastics.
Armature 1 bottom margin place is provided with bound edge 5, and bound edge 5 extends to the side of armature 1, until plastic fastening 3, bound edge 5 is structure as a whole with plastic fastening 3.
Insulator 4 bottoms have two plugs 41, and plug 41 also can be located at insulator 4 tops, and so structure can make plug 41 straight forming when injection moulding be connected armature fastening with movable contact spring.
The present invention at first makes injection mold, and plastic fastening, insulator, plug and the bound edge that outpours from injection molding machine is for being injection molded into when being structure as a whole by the mould one-shot forming with armature and movable contact spring.The structural member that this manufacture method produces can solve between armature and movable contact spring and be connected not fastening problem, and method is simple, and actual applicability is strong, the quality of Integral lifting relay, thus prolong its useful life.
Embodiment of the present invention does not consist of the restriction to the application's scope; every within the spirit and principle of the present invention design, any modification that one of skill in the art can make, be equal to and replace and improvement etc. all should be included within protection scope of the present invention.
