Abstract
This experiment is novel belongs to power automatic system device technique field, particularly the new-type push-and-pull electromagnetic contactor of one.This new-type push-and-pull electromagnetic contactor is characterized in that: comprise moving contact, fixed contact, contact pressure reed and arc-extinguish chamber, and contact pressure reed lower end is provided with touch spring, and contact pressure reed upper end is provided with telescoping mechanism, and telescoping mechanism upper end is provided with frame electromagnet.Structure is simple, easy to use; Startup and the stopping of Single button control contactor can be realized, because coil does not need to keep voltage after contactor adhesive, can not generate heat, can effectively reduce contactor aging, economize on electricity, increase useful life; Cost is low, easy to utilize.
Description
(1) technical field
The utility model relates to a kind of new-type push-and-pull electromagnetic contactor, belongs to power automatic system device technique field.
(2) background technology
Contactor is divided into A.C. contactor (voltage AC) and D.C. contactor (voltage DC), it is applied to electric power, distribution and electricity consumption, contactor broadly refers in industrial electro and utilizes coil to flow through current induced magnetic field, make contact closure, to reach the electrical equipment of control load, its operation principle is: when after contactor coil energising, coil current can produce magnetic field, the magnetic field produced makes fixed core produce the dynamic iron core of electromagnetic attraction attraction, and drive the action of A.C. contactor point, normally-closed contact disconnects, normally opened contact closes, both are interlocks, when the coil is de-energized, electromagnetic attraction disappears, armature discharges under the effect of retracting spring, contact is restored, normally opened contact disconnects, normally-closed contact closes.Its shortcoming 1. electromagnetic contactor coil is fragile, 2. due to contactor work time, solenoid need keep "on" position, consumed energy, and produce heat can cause contactor ageing of plastics, shorten its useful life.
Summary of the invention
The utility model, in order to make up the defect of prior art, provides a kind of structure simple, easy to use, only realizes a push-and-pull and contactor can be made to finish the work needs thus the new-type push-and-pull electromagnetic contactor extending its useful life.
The utility model is achieved by the following technical solution:
A kind of new-type push-and-pull electromagnetic contactor, it is characterized in that: comprise moving contact, fixed contact, contact pressure reed and arc-extinguish chamber, contact pressure reed lower end is provided with touch spring, and contact pressure reed upper end is provided with telescoping mechanism, and telescoping mechanism upper end is provided with frame electromagnet.
Wherein: described telescoping mechanism comprises runner A, runner B and vertical telescopic rail, it is inner that runner A and runner B is arranged on vertical telescopic rail, runner B is in runner A upper end, vertical telescopic rail limits the rotation of runner A and runner B, make it to carry out above-below direction to move, runner B upper end is provided with secured core and movable core successively, and movable core lower end is provided with pad and E shape ring.
Described frame electromagnet comprises coil and bobbin.The utility model is realized by following operation principle: during frame electromagnet energising, coil current can produce magnetic field, promotes movable core descending, direct drive telescoping mechanism, the interlock of compressing A.C. contactor moving contact, normally opened contact closes, and normally-closed contact disconnects, both interlocks, when the coil is de-energized, because telescoping mechanism is located, contactor can be made to remain closed operating state, if need to disconnect contactor, only need again to coil electricity.
The beneficial effects of the utility model are: structure is simple, easy to use; Startup and the stopping of Single button control contactor can be realized, because coil does not need to keep voltage after contactor adhesive, can not generate heat, can effectively reduce contactor aging, economize on electricity, increase useful life; Cost is low, easy to utilize.
