Description

Technical Field

[0001] The utility model relates to the technical field of readers and writers, in particular to a multi-channel reader and writer with ultra-high frequency. Background Art

[0002] The reader is generally considered to be a radio frequency identification (RFID) reading and writing terminal device. It can not only read radio frequency tags, but also erase and write data, so it is called a reader. The IC card reader is an important device for realizing data communication between IC cards and systems. The existing multi-port UHF RFID reader has multiple connectors, forming multiple channels to work simultaneously, and requires long-term uninterrupted operation. For example, a multi-port UHF RFID reader in China, with a patent announcement number (CN217085759U), realizes the function of clamping and preventing loosening by setting a clamping block to press on the upper end of the wiring. However, the plugging and unplugging of the clamping block and the wiring port are in the same direction, and it will still become loose after long-term use. In addition, the clamping assembly protrudes from the outside of the reader box, which is easy to touch by mistake and unsightly. Utility Model Content
