Abstract
The utility model relates to a magnetic arc extinguishing switch technology field. The utility model is designed for multiple-function, and comprises a shell. The outer of the shell has a pulley push rod, and the lower of the push rod has an intermediate ejector pin, and the intermediate ejector pin has a spring between the spring base and the inner surfaces of shell, and is connected with and fixes moving contacts on two sides through a snap spring. Correspondingly the shell is fixed with an upper static contact, a terminal strip and a binding screw, the two sides of the shell are provided with a magnetic arc extinguishing magnet according to the space of the moving and static contacts. The utility model is characterized in that the shell is also provided with a lower static contact and other terminal strip and binding screw according to the moving contact. The utility model has the advantages of less structure change, multiple functions, and less cost increase, and is suitable for popularization and application in industrial production.
Description
The utility model relates to magnetic quenching switching technique field.
Often to use the magnetic quenching switch in the industrial production, a kind of conventional magnetic quenching switch as shown in Figure 1, its structure is a housing, housing has the pulley push rod outward, middle push rod is arranged under the pulley push rod, and middle push rod has spring by between spring base and the housing inner chamber, and is connected and fixed the both sides movable contact spring by jump ring, be fixed with static contact and lug plate and terminal screw accordingly on the housing, the housing both sides are provided with magnetic quenching magnet at the active and static contact space.Its shortcoming: function is more single, has a kind of switching function, and meeting needs one to open make and break pass occasion, and two this switches will be installed, and causes cost to rise, and installation volume is big, inconvenient or the like.
The purpose of this utility model be to provide a kind of compact conformation rationally, the cost increase less, the magnetic quenching switch that increases of function.
The technical solution of the utility model is achieved in that this magnetic quenching switch includes housing, housing has the pulley push rod outward, middle push rod is arranged under the pulley push rod, middle push rod has spring by between spring base and the housing inner chamber, and be connected and fixed the both sides movable contact spring by jump ring, be fixed with static contact and lug plate and terminal screw accordingly on the housing, the housing both sides are provided with magnetic quenching magnet at the active and static contact space, it is characterized in that described housing also is provided with down static contact and its contact chip and terminal screw at movable contact spring.
Described magnetic quenching magnet is connected with pole piece in the housing both sides, and the both sides pole piece is at space between the active and static contact.
There is the bayonet socket of positioning and fixing movable contact spring described spring base both sides.
Magnetic quenching switch of the present utility model only increases static contact down, not only increase function, and structural change is less, and manufacturing cost increases few, and installs and uses more conveniently, suits to apply on industrial production.
Description of drawings:
Fig. 1. conventional magnetic quenching switch junctions composition;
Fig. 2. magnetic quenching switch junctions composition of the present utility model.
Below in conjunction with description of drawings embodiment of the present utility model is described further:
As shown in the figure, this magnetic quenching switch, include housing 5, housing has pulley push rod 1 outward, middle push rod 2 is arranged below the pulley push rod, middle push rod has spring 8 by between spring base 9 and the housing inner chamber, and be connected and fixed both sides movable contact spring 7 by jump ring 3, be fixed with static contact 4 and lug plate and terminal screw accordingly on the housing, the housing both sides are provided with magnetic quenching magnet 10 at the active and static contact space, it is characterized in that above-mentioned housing also is provided with down static contact 6 and its lug plate and terminal screw at movable contact spring.This switch suitable one closes a switch occasion like this.
Preferably, magnetic quenching magnet is connected with pole piece in the housing both sides, and the both sides pole piece is at space between the active and static contact, and to play good magnetic quenching effect, there is the bayonet socket of positioning and fixing movable contact spring the spring base both sides, and fixedly movable contact spring is more firm flexibly.
