The length is the length from one end of the golden finger welded with the PCB to the other end of the golden finger. This description means that the length of the second golden finger (i.e. the golden finger on the display card side) is lengthened by the device 100, so that after the first golden finger is inserted into the slot of the motherboard, the conductive contact is exposed with a sufficient length to perform the spot measurement for using the detecting instrument.

On this basis, after the device 100 is connected, the length of the ground conductive contact is extended to 6.2mm, while the lengths of the other conductive contacts are all extended to 6mm. In one possible embodiment, the detection unit 130 may be fixed to the base plate 140. The bottom plate 140 may be a PCB board. The first high-speed transmission end socket 110 and the first golden finger 120 are respectively fixed on two sides of the bottom plate 140.
In summary, the high-speed transmission link detection apparatus provided in the embodiment of the present disclosure includes: the first high-speed transmission end female seat, a first golden finger and a detection unit; wherein, this first high-speed transmission end female seat includes: the high-speed signal slot group comprises a high-speed signal receiving slot and a high-speed signal transmitting slot, and the first golden finger comprises a plurality of target line conductive contacts; the detection unit comprises a plurality of connecting wires, and the target circuit conductive contact is connected with the target circuit slot through the connecting wires; each connecting line is provided with a detection point.
