The utility model discloses a wire terminal for ignitor of tire explosion bulge test, a serial communication port, ignitor installs and waits to explode the position in tire surface to include heating element and make the electric power component that heating element heaied up, heating element's both ends respectively with the electric power component is connected through the wire terminal, and wherein, when taking place the blasting, at least one wire terminal keeps heating element with connection between the electric power component. When the tire took place the blasting, heating element and electric power component were thrown off in one end, and heating element's the other end is then firmly fastened by the electric power component for heating element is flare-outed down in air jet impact force effect, thereby prevents to blow up the heating element that ignitor was taken away to the pressure of abrupt release, has avoided effectively that blow up the test system or the testpieces leads to the fact the damage to the tire.
