Embodiment 1

[0037] Such as Figure 5 Shown, the segmented centralized high-density electrical measurement system, the system includes a test host 1, a plurality of electrode exchange devices (2, 3), cables 4 with taps and electrodes connected to the taps; wherein, the test The host 1, the electrode exchange device 2 and the electrode exchange device (2, 3) are connected in series through a cable. The cable 4 has a core 7 inside, and the core 7 is divided into a bus core 8 and a tap connected to the tap. Core 9. The electrode exchange device (2, 3) includes an exchange circuit 10 and a control circuit, wherein the control circuit has communication and power management functions; the number of taps is 7 to 15, preferably 10 to 12; the bus core 8 includes a transmitting circuit 5, The receiving circuit 6, the communication control circuit or / and the power supply circuit, the power supply circuit is optional, when the electrode exchange device 2 has a built-in working battery, the power supp...

Embodiment 2

[0039] Such as Figure 6 As shown, the segmented centralized high-density electrical measurement system is applied to IP high-density testing. The tap wire core 9 is truncated into the first wire end and the second wire end at the front and back positions, and what is connected with the first wire end and the second wire end respectively is to isolate the tap into the first signal contact point P1 and the second signal contact point P2, The front position is represented by P1, and the rear position is represented by P2; a set of identical switching circuits is added in the electrode exchange device 2; the tap core 9 is exchanged to the transmitting circuit of the bus core 8 through the electrode exchange device 2 5 and receiving loop 6. In this wiring mode, the first signal contact point P1 and the second signal contact point P2 of the tap are respectively connected to the electrode exchange device 2 at the front end and the rear end.

Embodiment 3

[0043] Such as Figure 7 As shown, the segmented centralized high-density electrical measurement system is applied to high-current testing. The transmitting loops 5 in the bus core 8 are connected in parallel. In the actual test, the transmitting circuit 5 needs to continuously carry the transmitting current, and the number of times any tap is used as the transmitting electrode is very small, that is, the empty-load ratio in actual work is much lower than that of the transmitting circuit 5 bus. Therefore, when considering the current carrying capacity, the wire diameter of the wire core connected to the tap on the cable may be only 1 / 3 to 1 / 4 of the transmission loop bus. Therefore, when determining the diameter of the wire core according to the maximum emission current, the wire diameter of the wire core to the tap can be reduced (the number of such wires accounts for the majority in the cable), and the wire diameter of the emission bus can be increased. For the convenience...
