A multi-interface read-only lock

Abstract

This invention discloses a multi-interface read-only lock, belonging to the field of read-only lock technology. The invention includes a housing and a backplate fixed to the housing. A main control chipset is installed inside the housing, and a power interface compatible with the power cord is provided on the front side of the housing. The backplate integrates an M.2 interface, a CF interface, an IDE interface, and an SD interface to support various data transmission cables and adapter modules. An overcurrent protection structure is provided at the edge of the power interface on the front side of the housing. This multi-interface read-only lock, by setting a limiting component at the power interface, uses the magnetic force of an electromagnet to control the limiting component to clamp and position the power cord when energized. Simultaneously, during overcurrent, the electromagnet's magnetic force changes due to the increased current, thereby automatically unplugging the power cord using magnetic force, preventing damage to the read-only lock from prolonged overcurrent and thus avoiding data loss.
