The utility model content
The purpose of this utility model is for the defective of above-mentioned prior art and deficiency, and for people provide a kind of simple in structure, easy for installation, difficult generation connects the arc phenomenon, and is applicable to control the miniature electro-magnetic relay of the break-make of high voltage.
technical solution adopted in the utility model is for achieving the above object: this electromagnetic relay, it comprises with the shell body of base and the insulating lid that fastens with shell body, be provided with a low pressure lug plate above insulating lid, two high-voltage connection sheets, static iron core and moving iron core are installed in shell body, the outside at static iron core has installed around coil, the low pressure lug plate is connected with coil, be installed with two binding posts in described insulating lid, two high-voltage connection sheets are connected with one of them binding post respectively, be movably installed with a plate between two binding posts, connecting plate be displaced downwardly to two binding posts on fixed contact offset, two binding posts are communicated with, be provided with insulating case between described coil and static iron core, moving iron core activity is flush-mounted in insulating case and is positioned at the top of static iron core, and the upper end of moving iron core can offset bottom direct or indirect and brace.
Arrange between described moving iron core and static iron core and be supported with moving iron core spring; Be supported with the connecting plate spring between the end face of described insulating lid and connecting plate.
The restoring force of described moving iron core spring is greater than the restoring force of connecting plate spring.
Moving up and down apart from the distance that moves up and down greater than connecting plate of described moving iron core.
Described moving iron core upper end is installed with jacking block, and when moving iron core moved up, jacking block can offset with connecting plate.
Described static iron core and shell body are adhesively fixed by resin glue.
The base of described shell body is triangle.
The utility model just can be controlled the break-make between two binding posts by coil electricity, discharge, has volume little, advantage simple in structure, as to be convenient to install, because moving iron core is not that direct drive connecting plate moves down, arcing phenomenon when therefore having reduced the touching of connecting plate and fixed contact or disengagement because the contact-making surface of connecting plate and fixed contact is large, also is applicable to control the break-make of high voltage, and improved the performance of shock resistance and vibrations, good market prospects are arranged.
