The invention relates to a converter comprising a connector. The connector comprises a first socket, a second socket, and a first short circuit plug and a second short circuit plug respectively fitting for the first socket and the second socket, wherein the first socket is a socket at the voltage withstand test side for connecting the wire to be shortened of the converter during the voltage withstand test, the second socket is a socket at the normal working side for connecting the wire to be detected of the converter during the normal working or the signal wire of the fault simulation. When the first short circuit plug is coordinately inserted in the first socket, the wire to be shortened in the first socket is shortened, when the second short circuit plug is coordinately inserted in the second socket, the wire to be shortened in the second socket is shortened. The converter provided by the invention not only satisfies the electrical performance requirement of the circuit, but also considers the convenient test operation and improved test efficiency, further provides the concentrated detection points for the converter and increases the feasibility of the fault simulation.
