Abstract
The invention discloses an electromagnetic type power master switch which comprises an electromagnetic component (11), an outer casing (3), a push rod (5), a movable contact piece (8) and a fixed electrode (9), wherein a plastic sleeve (6) is mounted between the upper top part of the push rod (5) and the outer casing (3); the outer casing is made of metal; the electromagnetic component (11) comprises an upper magnetic conductive plate (2) and a coil (4); and an inner iron ring (1) is mounted on the periphery of the coil and between the upper magnetic conductive plate and the lower part of the outer casing. According to the electromagnetic type power master switch, axial movement of the push rod is limited through the upper part of the outer casing, the pull-in distance inside a product is adjusted through the plastic sleeve, and accordingly, pull-in voltage becomes controllable and stable. The magnetic conductive plate, the inner iron core and the lower part of the outer casing wrap the coil wholly in a whole surrounding manner, so that the magnetic flux leakage quantity of the coil during working is reduced, the magnetic loss is smaller, the electromagnetic utilization ratio of the product is improved, the on-off capability of the product is enhanced, the product quality is improved on the whole, and the service life of the electromagnetic type power master switch is prolonged.
Description
Technical field
The present invention relates to the contactor that to connect or to cut off the electricity supply, be specifically related to a kind of electromagnetic power-supply general switch.
Background technology
At present, what conventional battery main switch adopted is that push rod (i.e. moving iron core) drives the movable contact spring member and whether movable contact spring member and fixed electrode are connected, realize the switch control of power supply, the radially activity of its push rod is constraint to be arranged and free relatively in axial motion, himself adhesive distance is only controlled by push rod deadweight and return spring, thereby causes the pick-up voltage of product integral body wayward and play pendulum.In addition, this battery main switch substantially all is that loose, the hypertelorism of this magnetic structure causes a large amount of magnetic losses by the magnetic loop effect between coil and the shell, make product can only take the very little return spring of power value (and excess of stroke spring), cause the drawback of product make-break capacity difference.Because battery main switch product pick-up voltage instability, pick-up voltage are difficult for regulating, cause drawbacks such as the product magnetic loss is big, contact point easy-sintering, and the battery main switch inefficacy meeting that is applied to automobile brings to automobile and expects too late hidden danger.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, and the electromagnetic power-supply general switch that provides a kind of pick-up voltage to stablize, be easy to regulate.
Purpose of the present invention realizes by following technical solution: electromagnetic power-supply general switch, comprise electromagnetic component, shell, push rod, movable contact spring member, fixed electrode, and between the upper top of described push rod and shell, plastic sheath is housed.
Described sheathing material is metal, and described electromagnetic component comprises upper conduction magnetic board, coil, in the periphery sides of described coil and locate to be equipped with interior iron ring between upper conduction magnetic board and outer casing underpart.
After adopting the present invention, the axial motion of push rod is limited by shell upper, and regulate the adhesive distance of product inside by plastic sheath, thereby make the pick-up voltage that is not easy to regulate originally become controlled, stablize.Because upper conduction magnetic board, interior iron ring and outer casing underpart encase coil with full encirclement formula integral body, magnetic flux leakage reduces when making coil working, magnetic loss is also less, thereby improved the electromagnetism utilance of product, make product can adopt the bigger return spring of power value, reduce the pressure drop between the contact, strengthened the make-break capacity of contact and unlikely sintering.Promote product quality on the whole, prolonged its useful life.Be specially adapted to the mains switch control of automobile, improve its security performance.
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 electromagnetic power-supply general switch of the present invention.
Embodiment
With reference to Fig. 1 as can be known, electromagnetic power-supply general switch of the present invention comprises electromagnetic component 11, shell 3, push rod 5 (i.e. moving iron core), movable contact spring member 8, fixed electrode 9, between the upper top of described push rod 5 and shell 3 (top) plastic sheath 6 is housed.Between the upper top of described push rod 5 and plastic sheath 6, pad 10 is housed, realizes the fine setting of product adhesive distance by adding pad.Wherein, on the push rod 5 return spring 12 is housed also; Push rod (i.e. moving iron core) part has been taked improvement, lengthened the length of whole moving iron core, it can have been limited by shell in axial motion, and can regulate inner adhesive distance by the plastic sheath at moving iron core top.
In order to reduce electromagnetic consumable, improve the electromagnetism utilance, described sheathing material is metal, and described electromagnetic component 11 comprises upper conduction magnetic board 2, coil 4 (having coil brace), iron ring 1 in the periphery sides of described coil 4 and in locating to be equipped with between upper conduction magnetic board 2 and shell 3 bottoms.The inner of described upper conduction magnetic board 2 extends to the inner side edge place of coil 4.The bottom that is metal shell has replaced original magnetic conductive board down, increased interior iron ring on the basis of former common power master switch, and original upper conduction magnetic board punching place stretched and extended to the inner side edge place of coil, make product electromagnetic circuit (upper conduction magnetic board 2, coil 4, metal shell 3 bottoms and interior iron ring 1) more closely, efficiently, improve the electromagnetism utilance, promoted properties of product.
