Description
Technical field
The present invention relates to a kind of contactor for being used to commutate to electric current or break-make controls.
Background technology
Contactor (belonging to relay) be it is a kind of in order to control commutated to line powering, to electric current or break-make control and
The electric equipment products of equipment, it is widely used in household appliance, industrial product.In recent years, as electric vehicle is (as dynamic in mixed
Power, fuel-cell vehicle etc.) development, contactor applies as its power switch.
Contactor is generally made of electromagnetic component, loading component, housing member, wherein：Electromagnetic component includes dynamic iron core, quiet
Iron core, coil (enameled wire), bobbin, magnetic sheet and cover board etc., housing member include upper cover shell, base, and loading component includes
Upper contact chip, lower contact chip, middle contact bridge, conductive sheet, fore-set, excess of stroke spring etc., magnetic sheet, cover board encase coil with half-packaging
And dynamic and static iron core, cause leakage field phenomenon to occur, magnetic loss is larger, electromagnetism utilization rate is relatively low.So as to have impact on the normal of contactor
Work, to institute its application electric appliance generation ill effect.
The content of the invention
It is an object of the present invention to overcome the above mentioned deficiencies, and provide that a kind of magnetic loss is smaller, electromagnetism utilization rate is high
Steady magnetic-type contactor.
The purpose of the present invention is achieved through the following technical solutions：Steady magnetic-type contactor, by electromagnetic component, loading component, shell
Body component forms, and wherein electromagnetic component includes dynamic iron core, static iron core, coil, bobbin, magnetic sheet and cover board, and housing member includes
Upper cover shell, base, loading component include upper contact chip, lower contact chip, middle contact bridge, conductive sheet, fore-set, excess of stroke spring,
There is bulge-structure on the magnetic sheet and connect with cover board, and insulating paper frame and magnetic are housed between the coil and the inner wall of base
Yoke.
The fore-set for being sequentially arranged with longitudinally disposed fore-set insulation sleeve between the fore-set and middle contact bridge, laterally setting
Insulation spacer.
After applying the present invention, coil is integrally encased by insulating paper frame, yoke and bobbin, and there is bulge-structure
Magnetic sheet can make it that magnetic flux leakage is reduced when coil, the work of dynamic and static iron core, and magnetic loss is also smaller, so as to improve electromagnetism utilization rate, carries
Contactor product quality has been risen, has extended its service life.
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 structure diagram of the steady magnetic-type contactor of the present invention.
Fig. 2 is the A-A sectional views of Fig. 1.
Fig. 3 is the connection diagram between fore-set and middle contact bridge in Fig. 1.
Embodiment
According to Fig. 1, Fig. 2, Fig. 3, the steady magnetic-type contactor of the present invention, by electromagnetic component (also known as electromagnetic assembly), load
Component, housing member composition, wherein electromagnetic component include dynamic iron core 18, static iron core 17, coil 11, bobbin 10, magnetic sheet 9 and lid
Plate 19, housing member include upper cover shell 7, base 13, and loading component includes upper contact chip 30, lower contact chip 23, middle contact
Bridge 21, conductive sheet 20, fore-set 24, excess of stroke spring 6, have on the magnetic sheet 9 bulge-structure 35 (being made by drawing process) and
Connect with cover board 19, and insulating paper frame 14 and yoke 15 are housed between the inner wall of the coil 11 and base 13.In the fore-set
The fore-set insulation spacer 32 for being sequentially arranged with longitudinally disposed fore-set insulation sleeve 31 between 24 and middle contact bridge 21, laterally setting.
Wherein, return spring 12 is housed, middle contact bridge 21, conductive sheet 20 are with above connecing between dynamic iron core 18 and static iron core 17
Contact 30, lower contact chip 23 are externally connected by flat contact, upper 30 external connection long threaded rod 1 of contact chip, lower contact chip 23
Connect short stud 34,20 external connection conductive stud 22 of conductive sheet.As shown in Figure 1 and Figure 2, turriform bullet is housed on the base 13
Spring 26, circuit board 27, glass lacquer pipe 28, the end of a thread lock sleeve 29, cover board 19 are placed on magnetic sheet 9, the bulge-structure 35 on magnetic sheet 9
In cover board 19.
When this contactor works, coil (enameled 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 the both ends of in-between contact bridge, conductive sheet is in contact with upper and lower contact chip；Finally by return
The return of spring and make that fore-set declines, dynamic iron core also declines.The contactor (relay) is mainly used in DC power supply load
Connecting and disconnecting of the circuit.
