Abstract
The utility model discloses an external-insulation contactor including an electromagnetic component(2), a movable contact bridge member (3) and a shell member (1); a spring seat (34) is riveted on a contact bridge (31) of the movable contact bridge member (3) and on a push rod (32) to fix an upper spring (35); and an insulator (4) is arranged between the electromagnetic component (2) and a base (13) of the shell member (1). Integral insulation, in which the whole connection part of the internal electromagnetic member and the outside is insulated, is employed in the external-insulation contactor so that the internal metallization degree of the contactor is higher and the assembly operation is more convenient and faster; heat resistance and work efficiency of the contactor are improved and hidden dangers are reduced; and the service life of the contactor is prolonged and the product quality is improved obviously.
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, 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 reed, 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 type contactor that temperature tolerance is high are provided.
Purpose of the present invention realizes by following technical solution: a kind of external insulation type 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, upper spring, riveting has spring base with fixing upper spring on the contact bridge of described movable contact bridge member and the push rod, 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 type contactor of the present invention.
Embodiment
With reference to Fig. 1 as can be known, external insulation type 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, upper spring 35, riveting has spring base 34 with fixing upper spring 35 (return is better) on the contact bridge 31 of described movable contact bridge member 3 and the push rod 32, and between the base 13 of described electromagnetic component 2 (its time magnetic conductive board 25) and housing member 1 insulator 4 is housed.
Wherein, this insulator 4 also extends between shell 11 and the base 13, and withstands on iron core 21 bottoms of electromagnetic component 2.Described electromagnetic component 2 comprises iron core 21, coil 22, 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 coil brace 23, 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.
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.
