Description
Technical field
The utility model relates to a kind of auto parts machinery, specifically refers to a kind of starter electromagnetic switch assembly.
Background technology
The starter of existing automobile generally is reducing motor, and it utilizes electromagnetic switch to be switched on or switched off current supply circuit, realizes starter work and closes.Existing electromagnetic switch structure generally all includes housing, solenoid, moving iron core, guide rod assembly and switch cover assembly, guide rod assembly comprises that guide rod and interlock are arranged at the contact on guide rod, switch cover assembly includes binding post and is arranged at the contact base of binding post the inner, the electromagnetic force that it produces by solenoid, drive moving iron core slippage in the screwed pipe of solenoid, so in drive leader assembly in contact and switch cover assembly contact base connect or disconnect.But the shortcoming of existing electromagnetic switch is: the structure of guide rod assembly arranges unreasonable, cause the guide rod shift motion of guide rod assembly long or too short, stroke is long cause contact and contact base strong collision impaired, the too short contact of stroke cannot fully contact and holding circuit conducting with contact base.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existing in order to overcome prior art, and provides a kind of structure to arrange rationally, and can effectively overcome long or the too short and starter electromagnetic switch assembly of the problems referred to above of bringing of traditional electromagnetic switch guide rod stroke.
For achieving the above object, the technical solution of the utility model is to comprise housing, solenoid, moving iron core, guide rod assembly and switch cover assembly, guide rod assembly comprises that guide rod and interlock are arranged at the contact on guide rod, switch cover assembly includes switch cover, be fixed on a pair of mutual discrete binding post on switch cover and be arranged at the contact base of binding post the inner, the setting corresponding with contact of described contact base, described solenoid is arranged in housing, described moving iron core slippage is arranged in the screwed pipe of solenoid, described guide rod comprises the axis of guide, projection is arranged at the limiting section on axis of guide sidewall and the connection part for being connected with contact, on described connection part, be provided with damping slippage cover and be furnished with contact plate, described contact is arranged at the two ends of this contact plate, between described switch cover and guide rod, be provided with guide rod back-moving spring, one end of the described corresponding switch cover assembly of housing is fixedly installed guide rod limited cover, in this guide rod limited cover, be provided with the direct bearing of guide rod to the axis hole coordinating, axis of guide the inner of described guide rod is stretched out outside axis hole and with moving iron core pushing tow and is coordinated, the outer end of described axis hole is provided with the limited wall of the spacing cooperation of limiting section of guide rod, and this guide rod limited cover relatively axial outer end of this limited wall is provided with the limiting section slippage slot coordinating with limiting section axial slip, between described limiting section and contact plate, be provided with contact plate buffer spring, the maximum length that stretch out outside axis hole described axis of guide the inner is greater than the maximum spacing between contact base and contact.
Operation principle and the effect of this setting are, under solenoid no power state, guide rod back-moving spring, drive leader resets, the limiting section of the guide rod making is limited on the limited wall of guide rod limited cover, now keep contact and contact base to be separated from each other, two binding posts are in off-state, when solenoid energising, solenoid drives moving iron core to move, the passive iron core of part stretching out in outside axis hole of the axis of guide of guide rod is pushed in axis hole, now, guide rod interlock contact plate phase contact base direction moves, contact in contact plate is in contact with one another with contact base and is communicated with, the maximum length of stretching out outside axis hole due to axis of guide the inner is greater than the maximum spacing between contact base and contact, therefore, in the trip process, between contact plate and contact base, always can touch, the stroke that effectively prevents guide rod is too short, and along with axis of guide the inner of the continuation pushing guide rod of moving iron core, now, this ejection force will make contact plate overcome the damping between itself and guide rod connection part, compression contacts plate buffer spring, until moving iron core pushes into axis of guide the inner of guide rod in axis hole completely, and this contact plate buffer spring is due in compressive state, active force near contact base of contact plate will be imposed on, this active force is by the abundant contact conducting keeping between contact and contact base, thus, this setting, can effectively prevent from making because guide rod stroke is long fierceness collision between contact and contact base, useful life of the present utility model and quality are improved.
The both sides that further setting is described contact plate are fixedly installed outer rubber circle and interior plastic seat, and this outer rubber circle, interior plastic seat are sheathed on the connection part of guide rod together with contact plate damping slippage.By this setting, because contact plate is generally metal material, damping and amortization is poor, and this arranges, to utilize outer rubber circle, interior plastic seat can be the suitable damping force that provides between contact plate and guide rod connection part.
On the outer face of the contact base of the binding post the inner described in further arranging, be provided with multiple tracks bar-shaped trough.By this setting, the setting of this bar-shaped trough, can reduce contact and contact base and occur at the fiery arc of disjunction moment.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
