This invention discloses a contact pin assembly in biosensor monitor, comprising of multiple contact pins, which has one end to fix to the printed circuit board, and which has the other end to contact with biosensor test strips to pick up the electrochemical signal from the biosensor test strips. The contact pins are angled to allow the backward movement of the auto-eject slider, and are suppressed by a protruded housing located on one side of the auto-eject slider to ensure better contact of the contact pins with the biosensor test strips.一種生化檢測儀器之試片訊號連接器結構,其中該生化檢測儀器係至少含有殼體及設於該殼體中之電路板,且於該電路板上,設置有一試片壓座,而該試片訊號連接器係包括:多數導電端子,各該導電端子係含有一中段,分別跨置於該試片壓座上,且於各該導電端子中段有一個折彎以利此生化檢測儀器的退試片機構後退而不卡到,該導電端子中段之第一側設有焊接段,以焊接於該電路板上,而於各該導電端子中段之第二側係延伸一訊號連接段者;以及,壓制部,一體成型於該殼體中,令該生化檢測儀器組裝完成後,該壓制部係與該試片壓座緊夾各該導電端子者;如是,使應用本新型之生化檢測儀器,於製造上,便不需要額外向外採購或自行製造該訊號連接器成品,以降低製造成本者。
