An electronic initiator unit for the electrical firing of a charge in an energetic device is described. The unit includes an actuation module comprising electrically in series a first conductor, an electronic actuator, and a second conductor; an engagement module including a first electrical connector conductively connected to the first conductor and defining a first connector contact portion spaced remotely from the first conductor and a second electrical connector conductively connected to the second conductor and defining a second connector contact portion spaced remotely from the second conductor; a shunt module including a first shunt connector defining a first shunt contact portion, a second shunt connector defining a second shunt contact portion, and a conductive shunt connection between the first and second shunt connector spaced remotely from the shunt contact portions; wherein the engagement module and the shunt module are co-operably configured so as to be engageable together such as to effect when so engaged an electrical connection between the first connector contact portion and the first shunt contact portion and between the second connector contact portion and the second shunt contact portion. A system and method for the electrical firing of a charge in a plurality of energetic devices in a controlled manner from a remote location are also described.

An electronic module includes a shunt resistor having one end that is connected to one end of a first ground wiring line and another end that is connected to another end of a second ground wiring line. Signal terminals are disposed to be close to the shunt resistor, the signal terminals including a first current detection terminal electrically connected to the one end of the shunt resistor, and a second current detection terminal disposed to be close to the shunt resistor and electrically connected to the other end of the shunt resistor. The shunt resistor is disposed to be close to a first side of a substrate along which the signal terminals are arranged.

In the X-shaped elastic support structure of the connector with socket in the present invention, an insertion hole is arranged in the middle of the connector cover plate of the connector, and an insulating seat is arranged inside the insertion hole, and the two conductive row ends of each layer of conductor connecting piece extend out of the insulating partition The pin groove is formed above the upper edge, and the X-shaped elastic body whose main body is a rubber composite shrapnel is supported in the space between the connecting pieces of the conductors of each phase, so that the conductive row of the connecting pieces of the conductors of each phase can clamp the pins of the plug-in box and improve the plug-in connection. Contact conductivity; and a U-shaped clip is set on the outermost conductor connecting piece to assist in clamping the two conductive rows of the outermost conductor connecting piece, further improving the electrical conductivity of the plug-in contact, the assembly operation is simple, the shunt current performance is stable and reliable, and can reduce The number of connectors and socket parts is small, and the packaging, transportation, installation, management and operation are convenient.

A capacitive discharge welding system includes at least one capacitive discharge-based power supply that is adapted to provide alternate polarity pulses from a first weld to a subsequent weld, and to be compatible with iron-core transformers used for alternating current resistance welding; at least one iron core transformer adapted to receive electrical discharges from the capacitive discharge-based power supply; a polarity switching network that includes at least two sets of silicon controlled rectifiers that are arranged in pairs for facilitating current flow in alternate directions; a pair of engagable, properly biased shunt diodes that are operative to shunt reflected current for protecting the silicon controlled rectifiers when the system is in use; and a control network configured for simultaneous engagement of the properly biased shunt diodes and firing the silicon controlled rectifiers for current flow; and tracking polarity for assuring that subsequent pulses use opposite direction current flow for preventing saturation of the iron core transformer.
