Abstract: An electrical connector assembly includes: a male connector, provided with a conductive shell; a first substrate, accommodated in the conductive shell and used to transmit receiving signals; a second substrate, accommodated in the conductive shell and used to transmit sending signals; a shielding sheet, located between the first substrate and the second substrate; a female connector, provided with a first conductive body and a second conductive body; a plurality of first signal terminals, accommodated in the first conductive body and used to transmit receiving signals; and a plurality of second signal terminals, accommodated in the second conductive body and used to transmit sending signals. The first signal terminals and the first substrate are electrically contacted to each other. The second signal terminals and the second substrate are electrically contacted to each other. The first conductive body and/or the second conductive body are used to lap joint with the shielding sheet.

Abstract: A combinable nucleic acid pre-processing apparatus includes a sample transfer chamber transferring a sample from a sampling tube to a nucleic acid extraction kit, a nucleic acid extraction chamber performing a nucleic acid extraction of the sample in the nucleic acid extraction kit for obtaining a nucleic acid extract, an assay setup chamber preparing reagents and transferring reagents and the nucleic acid extract to an assay plate, and at least two bridging modules respectively disposed between the sample transfer chamber and the nucleic acid extraction chamber and between the nucleic acid extraction chamber and the assay setup chamber. The sample transfer chamber, the nucleic acid extraction chamber and the assay setup chamber are separated and operated independently. Three chambers are connected through the bridging modules, so the nucleic acid extraction kit can be sequentially moved in the sample transfer chamber, the nucleic acid extraction chamber and the assay setup chamber.
