Abstract
The invention discloses a kind of contactless contactor contacts, including moving contact and static contact, movable contact is provided on moving contact, it is provided with stationary contact on static contact, mounting portion is provided on the moving contact, is provided with contact stem on mounting portion, mounting portion is welded and fixed with moving contact, contact stem is detachably connected with mounting portion, and the movable contact and stationary contact are separately positioned on the side of moving contact and static contact, and static contact upper surface is arcuate structure.Rationally, limit plate is arranged on static contact in easy to use, long service life, and static contact is decomposed to moving contact spring for structure of the invention design, switch in making process because arcing caused by secondary bounce weakens, so that the electrical endurance of switch extends.
Description
Technical field
The present invention relates to a kind of switch contact, in particular to a kind of contactless contactor contact.
Background technique
The switch contact of contactor currently used in the market is horizontal bridge architecture, and the contact of the structure type is switching
When connection, since movable feeler lever moves vertically with moving contact with respect to static contact, so that moving contact brings vertical impact to static contact,
The spring formed in this way by impact force easily causes to switch the secondary bounce arcing in making process, influences to switch with regard to bigger
Electrical endurance.
Summary of the invention
The object of the invention is that providing, one kind is reasonable in design, and easy to use, contactor with long service life is opened
Close contact.
To achieve the goals above, the technical solution adopted by the present invention is that it is such: contactless contactor contact of the invention,
Including moving contact and static contact, it is provided with movable contact on moving contact, stationary contact is provided on static contact, is arranged on the moving contact
There is mounting portion, contact stem is provided on mounting portion, mounting portion is welded and fixed with moving contact, and contact stem detachably connects with mounting portion
It connects, the movable contact and stationary contact are separately positioned on the side of moving contact and static contact, and static contact upper surface is arcuate structure.
Preferably, the moving contact and static contact are circle.
Preferably, being provided with limit plate on the static contact, limit plate, which is adopted, to be made from an insulative material.
Compared with the prior art, the advantages of the present invention are as follows: structure of the invention design is reasonable, easy to use, service life
It is long, limit plate is set on static contact, static contact is decomposed to moving contact spring, and switch is in making process because secondary bounce draws
The arcing risen weakens, so that the electrical endurance of switch extends.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings.
Referring to Fig. 1, contactless contactor contact of the invention, including moving contact 1 and static contact 2 is provided on moving contact 1 dynamic
Contact 3 is provided with stationary contact 4 on static contact 2, mounting portion 5 is provided on the moving contact 1, is provided with contact stem on mounting portion 5
6, mounting portion 5 is welded and fixed with moving contact 1, and contact stem 6 is detachably connected with mounting portion 5, and the movable contact 3 and stationary contact 4 divide
The side of moving contact 1 and static contact 2 is not set, and 2 upper surface of static contact is arcuate structure, and the moving contact 1 and static contact 2 are equal
For circle, it is provided with limit plate 7 on the static contact 2, limit plate 7, which is adopted, to be made from an insulative material.
Structure of the invention design is reasonable, easy to use, long service life, limit plate 7 is arranged on static contact 2, static contact 2 is right
1 spring of moving contact is decomposed, switch in making process because arcing caused by secondary bounce weakens, thus the electrical longevity of switch
Life extends.
