PURPOSE: An impact sensing device is provided to accurately install a sensor chip and to prevent the generation of failure because a joining direction between a housing and a connector unit is accurately guided in a process that a guide fixing rib is inserted into an insertion guide slot. CONSTITUTION: An impact sensing device comprises a housing(50), a connector unit(60), a substrate(74), an insertion guide slot(72), and guide fixing ribs(58). A mounting hole(52) is formed in the housing by penetrating a front end of the housing. An inner space(56) is formed in one side of the inside of the housing to be opened. The connector unit comprises an insertion unit(66) and a connection unit(62). A mounting space(68) formed in the inside of the insertion unit and a sensor chip(76) for sensing impact being installed in the inner space of the housing are installed on the substrate. The insertion guide slot is formed at a position corresponding to the mounting space formed in the insertion unit of the connector unit and the inner space of the housing. The insertion guide slot is formed in one side of the housing or the connector unit to guide the joining of the housing and the connector unit. The guide fixing rib is formed in one side of the connector unit opposite to a side where the insertion guide slot is formed or the housing and guided along the insertion guide slot so that a front end of the guide fixing rib pushes the substrate.
