Description
CONNECTOR BLOCK ; \ : Field of the Invention : p J —S
The invention relates to a connector block.
According to a first aspect of the invention, there is provided a connector block which ] 10 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.
One of the channels may be taken as the input end of signal transmission and one or more of the others, as the output end, 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.
The size and shape of channel may match the signal transmission line.
When the signal transmission line 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.
The signal transmission line may be inserted into the channel from one end, so that in use, the transmission line will be retained therein and locked by leaf spring.
The shock wave of one transmission line may be safely transferred to the other transmission lines.
The leaf spring may be released by pressing on a guide sleeve in the direction of its axis so that the transmission line may be pulled out of the channel.
Each receiving and retaining 200 LEA body may have a locating sleeve, a sealing ring at the outside of locating sleeve, a compression sleeve at the outside of sealing ring, a leaf spring at the outside of compression sleeve, a retaining sleeve at the outside of the leaf spring, the leaf spring being located and axially compressed between compression sleeve and second stepped shoulder of retaining sleeve, the guide sleeve being retained in the bore of retaining sleeve.
The leaf spring may be a radial elastic leaf spring which consists of triangularly ridged teeth with a hole at the center, of which all ridges are bent to the same side and all ends are connected with a circumferential ring to form a closed structure.
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, the retaining slot being made at the end of each channel, the outside contour of retaining sleeve having a boss thereon, the outside diameter of the retaining sleeve having the same inside diameter as the channel of the body, the inside contour of retaining sleeve being a stepped structure, the boss of the retaining sleeve matching with the retaining slot of the body.
The maximum outside diameter of compression sleeve may be a tight fit with the inside diameter of the body while the inside diameter of the compression sleeve is a clearance fit with the outside diameter of the signal transmission line.
The bore of the retaining sleeve may have two stepped shoulders therein, the outside diameter of the guide sleeve being a clearance fit with the inside diameter of the retaining sleeve, the boss of the guide sleeve entering and just falling into the first stepped shoulder in the bore of the retaining sleeve, the diameter of the boss of the guide sleeve being more than the inside diameter of the first stepped shoulder of the retaining sleeve, so that there is a clearance between the boss and the first stepped shoulder, the guide taper of the boss of the guide sleeve going forward and just falling into the cavity at the first stepped shoulder of the retaining sleeve, thus forming a buckle there, the center of the guide sleeve being hollow and the hollowness diameter being more than the outside diameter of the signal transmission line.
The center cavity may be formed by a spherical face of the locating sleeve at the connection of each channel and the spherical face of the body, the locating sleeve being retained in the body at the connection of each channel, the locating sleeve being hollow at the center and having a locating stepped shoulder therein near the center cavity.
The outside diameter of the sealing ring may be a tight fit with the inside diameter of the body, the inside diameter of the sealing ring having a radial elastic lip for holding the signal transmission line tightly in the ring.
The channel may consist of a guide sleeve, a leaf spring, a compression sleeve, a sealing ring, and a locating sleeve.
