Description
Technical field
The present invention relates to a kind of contactor, particularly relate to a kind of contactor adopting plastics fastener to fix fixed contact.
Background technology
Contactor is a kind of control apparatus of automation, and it utilizes coil to flow through current induced magnetic field, makes contact closure, to reach the electrical equipment of control load.Contactor is made up of electromagnetic system, contact system, arc-control device, insulation crust and annex etc. usually, electromagnetic system has generally comprised solenoid, dynamic iron core and static iron core, contact system includes moving contact, moving contact normally connects together with dynamic iron core and mutually to link, arc-control device is commonly used to rapid breaking arc, avoids burning out contact system.After the solenoid energising of contactor, can produce very strong magnetic field, make static iron core produce electromagnetic attraction and attract dynamic iron core, dynamic iron core is inhaled to having driven moving contact action during static iron core, the moving contact of moving contact is contacted with corresponding fixed contact, thus connects load power source; When solenoid power-off, magnetic attraction force disappears, and dynamic iron core interlock part relies on the reaction force of spring and is separated, and moving contact is disconnected, and namely the moving contact of moving contact is separated with corresponding fixed contact, thus cuts off load power source.Contactor includes static contact component, and static contact component is generally made up of contact plate and fixed contact, and fixed contact is fixed on contact plate, and contact plate is then be fixed on pedestal, whole static contact component is fixed on pedestal and matches with moving contact component.Fig. 1 is the syndeton schematic diagram between a kind of static contact component of prior art and pedestal, static contact component comprises contact plate 1 ' and fixed contact 10 ', pedestal 2 ' is provided with installing hole 21 ', when the static contact component of contactor is designed to pass through in a vertical manner the installing hole 21 ' of pedestal 2 ' and requires fastening, common mode leaves upper shoulder 11 ' in the both sides, top of the contact plate 1 ' of static contact component, the lower surface of the upper shoulder 11 ' of contact plate 1 ' is resisted against the upper end hole limit of installing hole 21 ', it is two italic structures 12 ' of diverging laterally that the stepped down part compartition that contact plate 1 ' end exposes pedestal is split into, italic structure 12 ' is made to be resisted against the lower stomidium limit of installing hole 21 ', by upper to installing hole 21 ' of the upper shoulder 11 ' of contact plate 1 ' and italic structure 12 ', lower stomidium limit clamps, thus make contact plate 1 ' be fixed in the installing hole 21 ' of pedestal 2 ', this structure, the shoulder 11 ' on contact plate 1 ' top can take the effective area of contact plate material (being generally copper coin), reduce materials'use rate, the step of bottom can increase the width of contact plate 1 ', thus increase the consumption of contact plate material.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art, a kind of contactor adopting plastics fastener to fix fixed contact is provided, that the convex closure arranging through-thickness on the top of the contact plate of static contact component carries out spacing, then adopt the holding of plastics fastener to carry out spacing in the middle and lower part of contact plate, make contact plate both sides that the shoulder of protrusion need not be set, regular shape, and substantially increase the utilance of contact plate copper product, thus reduce parts and product cost, the competitiveness of product in market is improved.
