Abstract
The utility model discloses a DC contactor. The DC contactor comprises a coil assembly, an arc extinguishing structure, a yoke and a moving contact assembly, which are arranged in a plastic shell. A coil leading-out wire of the coil assembly of the DC contactor, a static contact point and the sealed plastic shell are fixed via glass seal, an auxiliary contact of the DC contactor is based on a full-sealed microswitch, and the microswitch is in linkage connection with a connecting rod which is controlled by a controller to open and close and is equipped with a brake additionally. The DC contactor is based on permanent magnet type arc extinguishing and is made of a fireproof material, a coil of the DC contactor is equipped with an overvoltage protector, and the arc extinguishing structure is an arc extinguishing cover. The beneficial effects of the utility model are that the DC contactor is suitable for a glass sealing structure, and provides a reliable airtightness and a good environment adaptability.
Description
Technical field
The utility model relates to a kind of D.C. contactor.
Background technology
D.C. contactor on market mainly contains two kinds of structures, and a kind of is the structure of open type, and another is to adopt plastics to seal.The electric shock of unenclosed construction has been exposed in air, can only be used for the lower occasion of voltage, and general work voltage is no more than 100VDC; Plastic seal basically realized the electric shock with contactor be sealed in protective atmosphere but due to itself the impact of performance; the unfailing performance impact of the sealing between plastics and metal; the reliability of the sealing between plastics and metal is lower, and can not bear high temperature and thermal shock.
The utility model content
In order to overcome defects, the utility model provides a kind of contactor, and positiver sealing and good temperature applicability are provided, simultaneously simply small and exquisite, simultaneously without the arc extinguishing circle, low in energy consumption, extended useful life, non-maintaining, a kind of D.C. contactor of reduction user's maintenance cost.
For achieving the above object, technical solution adopted in the utility model is:
A kind of D.C. contactor, comprise coil block, arc extinguishing structure, yoke, moving contact component, coil block, arc extinguishing structure, yoke and moving contact component are arranged in plastic casing, fix by glass capsulation between the lead-out wires of coil of the coil block of described D.C. contactor, quiet contact point and sealed plastic shell, the auxiliary contact of described D.C. contactor adopts hermetically sealed sensitive switch, the bar linkage structure that sensitive switch and controller open and close is connected, and has additional brake on described sensitive switch; Described D.C. contactor adopts the magneto arc extinguishing; On the coil of described D.C. contactor, overvoltage protector is set, described D.C. contactor is that fire proofing material is made, and arc extinguishing structure is arc-extinguish chamber.
The utility model beneficial effect: D.C. contactor of the present utility model is suitable for the glass capsulation structure, and sealing and good environmental suitability reliably are provided; The auxiliary contact of contactor adopts the sensitive switch of totally-enclosed maintenance-free, and sand-proof is non-maintaining, has reduced user's maintenance cost, is provided with conveniently brake, the harmfulness decrease that causes because of the contactor fault.Adopt the permanent magnetism arc extinguishing, reduce failure rate, extended useful life, overvoltage protector is set, avoided the impact of overvoltage to contactor.
