[0002] The connector for RFID electronic seal packaging bags is an important connecting component for signal connection and transmission of electronic seal packaging bags. The importance of its structure directly affects the production and assembly of the component. The Chinese invention patent (patent number CN104103930B) discloses an electronic seal connector, which ensures good contact and signal stability through the cooperation of elastic probes and conductive columns. The longitudinal grooves and longitudinal protrusions can prevent the left and right and up and down deviations of the plug and socket to ensure signal stability. The plug and socket are adsorbed by magnetic blocks to achieve quick plugging and unplugging. The iron sheet is arranged on the outside of the magnetic block to prevent damage to increase its service life. The signal transmission line is connected to the elastic probe and the conductive column by filling. The electronic seal connector can also meet the needs of signal connection and transmission of electronic seal packaging bags, but it is a test for the assembly technology of the assemblers to make the elastic probes and the conductive posts accurately matched during assembly.
