Abstract
The invention discloses a digital electronic detonator bridge wire welding assembly, which comprises a circuit board, metal pieces, a bridge wire, and leads. The circuit board is designed with grooves and through holes matching with the metal pieces. The metal pieces are composed of three parts, i.e. groove parts, supporting parts, and bending parts, and the groove parts match with the grooves on the circuit board. The bridge wire is in connection with the leads that are placed inside the groove parts, and through welding, electrical connection with the metal pieces can be realized. The depths of the groove parts are the sum of the half of the circuit board thickness and the radius of the leads. The supporting parts are positioned on two sides of the groove parts along the lead direction, and through welding pads on two sides of the grooves on the circuit board along the lead direction, electrical connection with the circuit board can be realized. The bending parts include No.1 components that are connected and perpendicular to the groove parts, and No.2 components in connection with the No.1 components. The No.2 components run through the through holes on the circuit board, through welding, electrical connection with the circuit board can be realized, and the components can be buckled to the backside of the circuit board through artificial bending.
