Abstract
The utility model belongs to an electromagnetic connector wherein the base between the two sets of normal open contacts is spaced by the arc plate. The cover is disposed with wiring terminal for fixing the auxiliary contacts and delayer. The wiring terminal passes through the center of the base and directly connects to the elastic contact of the coil. The utility model has the advantages of simple structure, light product weight, firm and durable performances, low cost, eliminating the arc series and good security.
Description
Technical field
The utility model relates to a kind of electromagnetic treadle, belongs to the appliance applications technical field.
Background technology
But the traditional structure of contactor is to be provided with an electromagnet and a contactor that is subjected to this magnet control upper and lower displacement in base, and contactor comprises that position moving contact and be located at corresponding with this moving contact thereon often open fixed contact on the housing.This traditional contactor construction complexity, string arc phenomenon is serious, safety in utilization is low, processing and fabricating trouble, volume are big, heavy, the expense of taking a lot of work expect that so objective deficiency has limited the development and the application of contactor.
Summary of the invention
The purpose of this utility model provides a kind of electromagnetic treadle, and it is simple in structure that it is had, and product weight is light, sturdy and durable, cost is low, stop to go here and there arc phenomenon and the good advantage of safety in utilization.For this reason, the utility model adopts in the pedestal that two groups are often opened between the fixed contact up and down and separates with flash barrier, covers and is provided with the binding post that auxiliary contact and Ting Shi device annex are installed, and the terminals that cover pass the resilient contact of the middle tieline circle of base wall.The said structure design has realized the purpose of this utility model.
The utility model has the advantages that simple in structure, easy to process feasible, the formed product high conformity, sturdy and durable, high life, overall product is in light weight, thickness is moderate, cost is minimum, it is good to stop to go here and there arc phenomenon and safety in utilization.The utility model is not afraid of and is collided with, is not afraid of and falls, the reliability height, to transportation and mounting condition require low, convenient for users to use.
