Title:
HIGH-FREQUENCY RELAY WITH EXCELLENT SHIELDING PERFORMANCE
Document Type and Number:
WIPO Patent Application WO/2023/125445
Kind Code:
A1
Abstract:
A high-frequency relay with excellent shielding performance, which comprises a magnetic circuit part, a base part, and a moving reed part; the base part comprises an upper grounded shielding sheet, a lower grounded shielding sheet, at least two static reeds, and a plastic body which combines the lower grounded shielding sheet and the at least two static reeds into an integrated structure by a means of injection molding; each static reed has a static reed exposed part that is exposed at a surface of the plastic body, and the static reed exposed part is provided with a contact point used for making contact with the moving reed, a top face of the contact point being higher in the height direction than an upper surface of the lower grounded shielding sheet; the upper grounded shielding sheet is mounted on the plastic body and is higher in the height direction than the top faces of the contact points, and said sheet is grounded by means of the lower grounded shielding sheet. A shielded space that is grounded above and below is formed in correspondence with a signal transmission part within a relay, the shielding effect of the present invention is good, and the invention has the features of a simple molding process, being easy to implement, having good machining precision, and having high assembly efficiency and production efficiency.
