Abstract
The invention discloses an external insulation contactor which comprises an electromagnetic element (2), a movable contact bridge element (3) and a housing element (1), wherein a spring seat (34) is riveted on the contact bridge (31) and the push rod (32) of the movable contact bridge element (3); an upper spring (35) is mounted between the spring seat and the upper part of the outer housing (11) of the housing element; and an insulator (4) is mounted between the electromagnetic element (2) and the base (13) of the housing element (11). The external insulation contactor adopts integral insulation isolating the whole internal electromagnetic element from an external joint, so that the internal metallization degree of the contactor is higher, the assembling operation is more convenient and quicker, the temperature resistant performance and the work efficiency of the contactor are improved, potential safety hazards are reduced, the service life of the contactor is prolonged, and the product quality is remarkably improved.
Description
Technical field
The present invention relates to a kind of for the contactor that electric current is commutated or break-make is controlled.
Background technology
Contactor is a kind of in order to control to line powering, electric current to be commutated or break-make control and the electric equipment products of equipment, and it is widely used in home appliances, the industrial product.
Contactor is generally by electromagnetic component, movable contact bridge member, housing member is formed, wherein: electromagnetic component comprises iron core, coil (and coil brace), upper conduction magnetic board and following magnetic conductive board, housing member comprises shell, fixed electrode, base, movable contact bridge member comprises contact bridge, push rod, the overtravel spring, contact bridge and push rod are metalwork, between this contact bridge and the push rod insulating sleeve is housed, insulating parts such as insulation spacer, because the moment working temperature of contactor inside is very high, and this inbuilt insulating part temperature tolerance is relatively poor, just reduced the useful life of insulating part undoubtedly, thereby influenced the use of electric equipment products.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, and a kind of insulating part fitted outside, external insulation contactor that temperature tolerance is high are provided.
Purpose of the present invention realizes by following technical solution: a kind of external insulation contactor, comprise electromagnetic component, movable contact bridge member, housing member, wherein housing member comprises shell, fixed electrode, base, movable contact bridge member comprises contact bridge, push rod, overtravel spring, riveting has spring base on the contact bridge of described movable contact bridge member and the push rod, between the shell upper of this spring base and housing member, upper spring is housed, and between the base of described electromagnetic component and housing member, insulator is housed.
After adopting the present invention, because insulator is contained in the position close to shell, work high-temperature region away from fixed electrode, contact bridge and push rod, adopted the integral insulation of isolated whole internal electromagnetic member and outside junction, made that contactor internal metallization degree is higher, assembly manipulation is more convenient, its heat resistance and operating efficiency have been improved, also reduce potential safety hazard, made that the life-span of contactor is more lasting, made product quality obtain obvious lifting.
Description of drawings
The present invention is described in further detail below in conjunction with accompanying drawing and execution mode.
Fig. 1 is the structural representation of external insulation contactor of the present invention.
Embodiment
With reference to Fig. 1 as can be known, external insulation contactor of the present invention, comprise electromagnetic component 2, movable contact bridge member 3, housing member 1, wherein housing member 1 comprises shell 11, fixed electrode 12, base 13, movable contact bridge member 3 comprises contact bridge 31, push rod 32, overtravel spring 33, riveting has spring base 34 on the contact bridge 31 of described movable contact bridge member 3 and the push rod 32, between shell 11 tops of this spring base 34 and housing member 1, upper spring 35 (return is better) is housed, and between the base 13 of described electromagnetic component 2 (it is magnetic conductive board 25 down) and housing member 1, insulator 4 is housed.
Wherein, described electromagnetic component 2 comprises iron core 21, coil 22 (and coil brace 23), upper conduction magnetic board 24 and following magnetic conductive board 25, iron ring 26 in outside this coil 22 and between upper conduction magnetic board 24 and following magnetic conductive board 25, locating to be equipped with, this upper conduction magnetic board 24, following magnetic conductive board 25 and interior iron ring 26 encase coil 22 with full encirclement formula integral body, magnetic flux leakage reduces when making coil working, magnetic loss is also less, thereby has improved the electromagnetism utilance.This insulator 4 also extends between shell 11 and the base 13, and withstands on iron core 21 bottoms of electromagnetic component 2.
During the work of this contactor, coil is put iron core on the spot and is produced magnetic field, and iron core is risen with the push rod rising of magnetic force drive activity contact bridge member, and the two ends of its contact bridge are contacted with two fixed electrodes, and push rod decline, iron core are also descended.This contactor is mainly used in the connecting and disconnecting of the circuit of DC power supply load.
