Abstract
The utility model relates to an improved direct current contactor on the basis of original contactor, which is a normally closed-type contactor. A contact pressure spring is disposed on one end of a guide shaft. One end of the pressure spring is pressed tightly on steps below the guide shaft and the other end is pressed tightly inside a fixed iron core. The structure facilitates the moving contact and the fixed iron core in normally closed state. In power failure or breaking down, coils generate electromagnetic effect in power turn-on, the movable iron core generates push power and the fixed contact is disconnected with the movable contact. The utility model is mainly used in power supply switch of program control power source and uninterruptable power supply system and is also used in traction engine, mineral machine, petrochemical engineering, metallurgy, shipbuilding, telecommunication, computer power supply and other fields.
Description
The utility model is the low-voltage direct contactor after a kind of the improvement.
The general low-voltage direct contactor that uses mainly is to produce magnetic field by the coil electricity in the contactor to make the moving iron core in the contactor produce thrust on the current market, and the moving contact that promotes in the contactor contacts the conducting entire circuit with fixed contact.But in some industry such as post and telecommunications, programmable power supply, the employed D.C. contactor in fields such as computer uninterrupted power supply needs long conducting, thereby the coil in the D.C. contactor must be among the "on" position for a long time, conduction time is long, and coil is easy to heating, wastes electric energy so on the one hand, produce the aging of relevant material owing to being in febrile state for a long time on the other hand, thereby influence the life-span that D.C. contactor uses.
The purpose of this utility model just is to provide the D.C. contactor after a kind of the improvement, and the coil that can make D.C. contactor is not charged and moving contact contact with the fixed contact normally closed type when work, has improved the life-span of D.C. contactor use.
The structure of the utility model D.C. contactor is mainly by quiet, and electromagnetism adhesive structure two major parts of moving contact normally closed type structure and coil are formed.
Below in conjunction with accompanying drawing the utility model D.C. contactor is elaborated.
Fig. 1 is the utility model D.C. contactor profile.
The fixed contact of D.C. contactor (9) and moving contact (8) are in band, and to close the way of contact be that by moving contact (8) and guide shaft (3) one is connected as a single entity by insulating case (5) and nut (6), and penetrate in the static iron core (10), one of guide shaft (3) in static iron core (10) has a step-like structure, there is a contact pressure spring (4) to produce the normally closed structure of elastic compression moving contact (8) and fixed contact (9) above, meanwhile also can regulate pressure between two contacts by adjusting nut (6), under normal operative condition, be among the normally off between fixed contact (9) and the moving contact (8), be provided with electric current in contactor coil this moment (2) and pass through.When contactor breaks down or cut off the power supply, control circuit imports electric current by coil lead (7) and produces galvanomagnetic effect in coil (2), iron core (1) is upwards produced to be promoted, when promoting guide shaft (3), overcome the pressure of contact pressure spring (4) and moving contact (8) and fixed contact (9) are disengaged, contact is disconnected.There is a pad (11) on moving iron core (1) top and in the hole of moving iron core (1) head a buffer spring (12) is arranged, (12) one of its buffer springs are pressed on the pad (11), the other end is pressed in the moving iron core (1), and it is moving to be mainly used to anti-stop iron core (1) string.Thereby D.C. contactor of forming by coil (2), moving iron core (1), buffer spring (12), pad (11), static iron core (10), guide shaft (3), contact pressure spring (4), fixed contact (9), moving contact (8), insulating case (5) and nut (6), its feature is installed with a contact pressure spring (4) of guide shaft (3), the one head is pressed on the step of guide shaft (3) lower end, and the other end is pressed in the static iron core (10).A pad (11) is arranged on moving iron core (1), abut against the bottom of guide shaft (3) above it.In the hole of moving iron core (1) head a buffer spring (12) is arranged, the one head is pressed on pad (11) bottom, and the other end is pressed in the moving iron core (1).Guide shaft (3) selects for use stainless steel material to make.
The utility model D.C. contactor is to have done improvement on the basis of original contactor, be a kind of normally closed type contactor, thereby make the coil of D.C. contactor not charged when work, saved electric energy on the one hand, has improved useful life again the other end, has good economic benefit.Its power supply that is mainly used in programmable power supply switches and uninterruptible power system, also can be used for traction locomotive, mineral products machinery, petrochemical industry, metallurgical boats and ships, telecommunications, fields such as computer power supply control.
