UNIVERSAL CIRCUIT BOARD OF SHORT-CIRCUITING BAR

摘要

A universal circuit board (100) of a short-circuiting bar. The universal circuit board (100) comprises a circuit board substrate (1), and signal inputting interfaces (2) and signal outputting interfaces (3) all borne on the circuit board substrate (1). The signal inputting interfaces (2) are of at least two types and are used for inputting different signals. Different output signals are output through the signal outputting interfaces (3). Inputting pins (20) of the signal inputting interfaces (2) are in one-to-one butt joint with outputting channels (30) of the signal outputting interfaces (3). By setting a specific wiring mode between the inputting pins (20) of different signal inputting interfaces (2) and the outputting channels (30) of the signal outputting interfaces (3), different signal inputting interfaces (2) can be connected to a same circuit board (100), thereby implementing signal switching of different types of products.
