Connector for igniting circuit of priming device

A connector for an igniting circuit connecting an igniting signal generator and a priming device, comprising:

• a first connector member which is connected to said priming device through signal lines;
• said first connector member comprising:
• a casing made of insulating material and provided with an axially extending cavity;
• a ground terminal made of electric conductive material, which is connected to a ground line and projects into said cavity in the axial direction thereof;
• and
• a pair of signal terminals made of electric conductive and elastic material, which are connected to said signal lines of said priming device respectively and project into said cavity in the axial direction thereof at a predetermined distance from said ground terminal, one portion of each of said signal terminals being elastically contacted with said ground terminal;
• and
• a second connector member which is connected to said igniting signal generator through signal lines and is to be engaged with said first connector member;
• said second connector member comprising:
• a casing made of insulating material and provided with an axially extending cavity opposing to said cavity of said first connector member;
• a projecting portion made of insulating material, which is axially formed within said cavity and provided with an axially extending slot for receiving said ground terminal therein;
• and
• a pair of signal terminals made of electric conductive material, which are disposed along said projecting portion so as to be opposed to each other;
• and are connected to said signal lines of said igniting signal generator;
• whereby when said first connector member is engaged with said second connector member, said ground terminal is inserted within said slot formed in said projecting portion of said second connector member and said pair of signal terminals of said first connector member are separated from said ground terminal by said projecting portion and then connected to said signal terminals of said second connector member respectively.
