Abstract
The utility model discloses a small size big power relay which includes a cover housing, a pedestal, a coil rack, an iron core, an armature, a yoke, a movable contact, a normally closed static contact, and an normally open static contact. The coil rack is wound with a coil. The small size big power relay is characterized in that at least one of the normally open static contact and the normally closed static contact is integratedly provided with two parallel leading feet. The advantages are that because the static contact is provided with two parallel leading feet, the radiating area of the leading feet of the static contact is increased, and the switching capacity of a contact point of the static contact is increased. The performance of the relay is improved. Besides, because the cover housing is provided with radiating holes, the heat radiation of the relay can be guaranteed in operation, and the working reliability of the relay is also increased.
Description
Technical field
The utility model relates to a kind of relay, relates in particular to a kind of small high-power relay.
Background technology
Along with the development of society, the purposes of relay more and more widely, and kind is also more and more, function and structure also have nothing in common with each other.In the present small high-power relay, its static contact basically all is single leading foot, has caused the area of dissipation of static contact leading foot little, has also reduced the switching capability of static contact upper contact.
Summary of the invention
The utility model technical problem to be solved provides a kind of small high-power relay that increases the area of dissipation of static contact leading foot and can improve the switching capability of static contact upper contact.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of small high-power relay; Comprise case, base, bobbin, iron core, armature, yoke, movable contact spring, normally closed static contact and Chang Kai static contact; Described bobbin is connected with described base one; Be wound with coil on the described bobbin; Described yoke inserts between the bottom surface and described base of described bobbin, is set with the contact respectively on described movable contact spring, normally closed static contact and the Chang Kai static contact, and described often opening at least one of static contact and described normally closed static contact is wholely set two leading foots arranged side by side.
Described often opening is wholely set two leading foots arranged side by side on the static contact.
Be wholely set two leading foots arranged side by side on the described normally closed static contact.
Describedly often open on static contact and the described normally closed static contact all that one is provided with two leading foots arranged side by side.
The end face of described case is provided with air-vent, and the position of described air-vent is positioned at an end at relay actuator place and departs from the position directly over the case contact.
Compared with prior art; The utility model has the advantages that because static contact is provided with two leading foots arranged side by side, increased the area of dissipation of static contact leading foot, also played shunting action simultaneously; Increase the switching capability of static contact upper contact, improved the performance of relay; In addition, because case is provided with air-vent, can ensure that relay has good heat radiation at work, has improved the functional reliability of relay.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure; A kind of small high-power relay; Comprise case 1, base 2, bobbin 3, iron core 4, yoke 5, armature 6, movable contact spring 7, normally closed static contact 8 and Chang Kai static contact 9, bobbin 3 is connected with base 2 one, is wound with coil 31 on the bobbin 3; Yoke 5 inserts between the bottom surface and base 2 of bobbin 3; Be set with the contact respectively on movable contact spring 7, normally closed static contact 8 and the Chang Kai static contact 9, often open and be wholely set two leading foots arranged side by side 91 on the static contact 9, often open the leading foot 91 of static contact 9 and the leading foot difference protuberate basic unit 2 of normally closed static contact 8; The end face of case 1 is provided with air-vent 11, and the position of air-vent 11 is positioned at an end at relay actuator place and departs from the position directly over case 1 contact.
Except that structure shown in the foregoing description, can also on normally closed static contact 8, be wholely set two leading foots arranged side by side.
Claims (5)
1. small high-power relay; Comprise case, base, bobbin, iron core, armature, yoke, movable contact spring, normally closed static contact and Chang Kai static contact; Described bobbin is connected with described base one; Be wound with coil on the described bobbin; Described yoke inserts between the bottom surface and described base of described bobbin, is set with the contact respectively on described movable contact spring, normally closed static contact and the Chang Kai static contact, it is characterized in that described often opening at least one of static contact and described normally closed static contact is wholely set two leading foots arranged side by side.
