Description
Technical field
The present invention relates to a kind of contactor for being used to commutate to electric current or break-make is controlled.
Background technology
Contactor (belonging to relay) be it is a kind of in order to control to be commutated to line powering, to electric current or break-make is controlled and
The electric equipment products of equipment, it is widely used in home appliances, industrial product.Contactor it is general by electromagnetic component, loading component,
Housing member is constituted, wherein：Electromagnetic component includes dynamic iron core, coil (enamel-covered wire), coil rack, magnetic guiding frame and magnetic conduction fixed plate
Include upper cover shell, base Deng, housing member, loading component includes upper contact chip, lower contact chip, middle contact bridge, curved contact
Bridge, fore-set, excess of stroke spring, return spring etc., fore-set and fore-set metallic sheath be directly installed in base content it is easy to wear, position it is bad,
And directly contacted during dynamic iron core work with the inwall of upper cover shell, vibrations are larger, so that the normal work of contactor is have impact on, it is right
Its application electrical equipment produce ill effect.
The content of the invention
It is an object of the present invention to overcome the above mentioned deficiencies, and provide it is a kind of can make fore-set etc. effectively positioning, wear-resisting subtract
Shake positioning formula contactor.
The purpose of the present invention is achieved through the following technical solutions：Damping positions formula contactor, by electromagnetic component, load structure
Part, housing member composition, wherein electromagnetic component include dynamic iron core, coil, coil rack, magnetic guiding frame and magnetic conduction fixed plate, housing
Component includes upper cover shell, base, loading component include upper contact chip, lower contact chip, middle contact bridge, curved contact bridge, fore-set,
Excess of stroke spring, return spring, be sequentially arranged between the fore-set and middle contact bridge fore-set metallic sheath, fore-set insulation sleeve and
The fore-set insulation spacer laterally set, metal spacer is equipped with the base and in the unilateral side of the middle contact bridge.
Beam is housed on the inwall of the upper cover shell of the housing member and at the top of dynamic iron core, to reach
Damping effect.
, will not be right again because fore-set, fore-set metallic sheath etc. are contacted with metal spacer and by its positioning after the present invention
Base causes direct abrasion, and firm position, wear-resisting good, when dynamic iron core is worked up due to the setting of beam, to dynamic
Iron core also will not directly touch the inwall of upper cover shell there will be no larger vibrations, so as to improve contactor product
Quality, decreases potential safety hazard so that the life-span of contactor is more lasting.
Brief description of the drawings
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation that damping of the present invention positions formula contactor.
The lateral view (removing curved bridge stud etc.) that Fig. 2 is Fig. 1.
Fig. 3 is the connection diagram between fore-set in Fig. 1 and middle contact bridge, metal spacer.
Embodiment
Reference picture 1, Fig. 2, Fig. 3 understand that damping of the present invention positions formula contactor, by electromagnetic component (also known as electromagnetic assembly),
Loading component, housing member composition, wherein electromagnetic component include dynamic iron core 30, coil 27, coil rack 21 (and coil set 22),
Magnetic guiding frame 28 and magnetic conduction fixed plate 26, housing member include upper cover shell 2, base 1, loading component include upper contact chip 3, under connect
Contact 4, middle contact bridge 23, curved contact bridge 5, fore-set 18, excess of stroke spring 17, return spring 9 (and spring base 25), on the top
Fore-set metallic sheath 15 (copper material is contacted with fore-set outside), fore-set insulation sleeve 14 are sequentially arranged between post 18 and middle contact bridge 23
(being contacted inside with middle contact bridge) and the fore-set insulation spacer 16 laterally set, on the base 1 and in this indirectly
The unilateral side for touching bridge is equipped with metal spacer 37 (stainless steel).One side i.e. between the base and middle contact bridge is equipped with
Metal spacer 37.
Wherein, middle contact bridge 23, curved contact bridge 5 are contacted with upper contact chip 3, lower contact chip 4 by flat contact 24, on
The external connection long threaded rod 8 of contact chip 3, the lower short stud 7 of the external connection of contact chip 4, the curved curved bridge stud 6 of the external connection of contact bridge 5.Line
The end of ring framework 21 is connected by coil contact pin 39 with inserted sheet 31, and the inserted sheet is extended to outside base.In the housing member
Beam 38 (elastomeric material) is housed, to reach damping effect on the inwall of upper cover shell 2 and at the top of dynamic iron core 30.
When this contactor works, coil (enamel-covered wire) puts dynamic iron core on the spot and produces magnetic field, dynamic iron core is increased and is driven with magnetic force
The fore-set of loading component rises, and contact bridge, the two ends of curved contact bridge are in contact with upper and lower contact chip between making wherein, finally by returning
The return of position spring and make that fore-set declines, dynamic iron core also declines.The contactor (relay) is mainly used in dc source load
Connecting and disconnecting of the circuit.
