Abstract
The invention discloses an electromagnetic power main switch. The electromagnetic power main switch comprises an electromagnetic component (11), a shell (3), a push rod (5), a movable contact piece component (8) and a fixed electrode (9). The shell is made of metal, the electromagnetic component (11) comprises an upper magnetic board (2) and a coil (4), and inner iron rings (1) are arranged on the periphery of the coil and between the upper magnetic board and the lower portion of the shell. A plastic sleeve (6) is arranged between the upper top portion of the push rod (5) and the shell (3). Due to the fact that the coil is wrapped by the upper magnetic board, the inner iron and the lower portion of the shell in a full surrounding mode, magnetic flux leakage quantity in the working process of the coil is lowered, magnetic losses are small, and therefore the electromagnetism utilization rate of products is improved and make-break capacity of the products is enhanced. Axial movement of the push rod is limited through the upper portion of the shell, pull-in distances inside the products are adjusted through the plastic sleeve, therefore, pull-in voltages become controllable and stable, quality of the products is wholly improved, and the service life of the products 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 type battery main 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 type that a kind of magnetic flux leakage is little, magnetic loss is little, the electromagnetism utilance is high battery main switch is provided.
Purpose of the present invention realizes by following technical solution: the electromagnetic type battery main switch, comprise electromagnetic component, shell, push rod, movable contact spring member, fixed electrode, described sheathing material is metal, 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.
Between the upper top of described push rod and shell, plastic sheath is housed.
After adopting the present invention, 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, reduced the pressure drop between the contact, strengthened the make-break capacity of contact and unlikely sintering.The axial motion of push rod limits by shell upper, and regulates the adhesive distance of product inside by plastic sheath, thereby makes the pick-up voltage that is not easy to regulate originally become controlled, stablize.Thereby promoted product quality generally, 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 type battery main switch of the present invention.
Embodiment
With reference to Fig. 1 as can be known, electromagnetic type battery main switch of the present invention, comprise electromagnetic component 11, shell 3, push rod 5 (i.e. moving iron core), movable contact spring member 8, fixed electrode 9, described sheathing material is metal, 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, coil, metal shell bottom and interior iron ring) more closely, efficiently, improve the electromagnetism utilance, promoted properties of product.
For the pick-up voltage that makes the battery main switch product becomes controlled, stablizes, 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 push rod (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.
