Abstract: Embodiments of the present invention disclose a connector block that has at least two channels therein for connecting one signal transmission line with multiple signal transmission lines in a blasting system for transferring blasting signals, wherein one of the channels is the input end of signal transmission and one or more of the others are output ends, and wherein each channel is opened to a center cavity, thus enabling the input end and output end of transmission line to transfer the blasting signal through center cavity.

Abstract: The invention provides a connector block which has at least two channels (18) therein for connecting one signal transmission line (20) with multiple signal transmission lines (20) in a blasting system for transferring blasting signals. One of channels (18) can be taken as the input end of signal transmission and the other one (or ones), as the output end. Wherein each channel (18) is opened to center cavity (16), thus enabling the input end and output end of transmission line (20) to transfer the blasting signal through center cavity (16). The size and shape of channel (18) matches signal transmission line (20). When signal transmission line (20) is inserted into a channel from one end, it will be received and retained in the channel and the blasting signals are transferred through center cavity (16).
