Definitions
- Three of the ports may have the inner and secondary sleeves.
- the size and shape of channel may match the signal transmission line.
- the shock wave of one transmission line may be safely transferred to the other transmission lines.
- the body may include channels which transit from the center cavity to the ends of all channels including their transition sections, or from the small diameter sections at the center part to the large diameter sections at the ends of all channels which form the ports.
- a multi-port transmission line connector having a body which has at least four ports and channels therein for connecting one signal transmission line with three or more signal transmission lines in a blasting system for transferring blasting signals, the at least four ports having one or more recess or slot for securing a complementary plug having two or more lateral protrusions which engage the recess or slot to secure a plug to a port.
- the plug may have a finger engageable portion which facilitates rotating the plug in the port thereby to secure the plug in the port.
- the ports may include securing means for securing the signal transmission lines relative to the channels.
- the plug into which the signal transmission line is secured and inserted into a port from one end it may be received and retained in the port and the blasting signals is thus transferred through the centre cavity.
- the body may include channels which transit from the centre cavity to the ends of all channels including their transition sections.
- a transmission line system for connecting 5 or more detonators at least three of which are distributed over several boreholes and transmitting a shock wave from one transmission line to 4 or more other connected transmission lines, said system including a transmission line connector having a body which has at least five channels therein for connecting one signal transmission line with 4 or more signal transmission lines in a blasting system for transferring blasting signals, the channels having securing means for securing the transmission lines thereto.
- the system may include several transmission line connectors connected together by signal transmission means for connecting detonators placed in boreholes in a configuration which requires at least one set of five detonators to be in detonation signal communication whereby one of the detonators transmits a detonation signal to four or more other detonators in the system.
- Figure 3 shows a five port connector block of the invention
- the invention extends to a method of connecting a plurality of detonators in boreholes whereby the detonation sequence requires one or more detonators to each transmit a detonation signal to 4 or more detonators for the propagation of a blast, said transmission of the detonation signal being by means of a transmission line connector of the invention, for example, as shown in Figure 4.
