Connector block

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.

1 . A connector block 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, 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. 
     
     
         2 . A connector block as claimed in  claim 1 , wherein the size and shape of channel matches the signal transmission line, wherein when 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. 
     
     
         3 . A connector block as claimed in  claim 1 , wherein, in use, the signal transmission line is inserted into a channel from one end in the operation, and then the transmission line will be retained therein and locked by a leaf spring, whereby the shock wave of one transmission line is safely transferred to the other transmission lines. 
     
     
         4 . A connector block as claimed in  claim 1 , wherein, in use, a guide sleeve is pressed in the direction of its axis and the leaf spring will be open, then the transmission line can be pulled out of the channel. 
     
     
         5 . A connector block as claimed in  claim 1 , wherein each receiving and retaining channel of the body has a locating sleeve, a sealing ring at the outside of the locating sleeve, a compression sleeve at the outside of the sealing ring, the leaf spring located at the outside of the compression sleeve, a retaining sleeve at the outside of the leaf spring which leaf spring is located and axially compressed between compression sleeve and second stepped shoulder of the retaining sleeve, with the guide sleeve being retained in the bore of the retaining sleeve. 
     
     
         6 . A connector block as claimed in  claim 1 , wherein the leaf spring is 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. 
     
     
         7 . A connector block as claimed in  claim 1 , wherein the maximum outside diameter of the compression sleeve is a tight fit with the inside diameter of the body while the inside diameter of compression sleeve is a clearance fit with the outside diameter of the signal transmission line. 
     
     
         8 . A connector block as claimed in  claim 1 , wherein the bore of the retaining sleeve has two stepped shoulders therein, the outside diameter of the guide sleeve being a clearance fit with the inside diameter of the retaining sleeve, a boss of the guide sleeve enters and just falls into first stepped shoulder in the bore of the retaining sleeve, the diameter of boss of the guide sleeve being more than the inside diameter of the first stepped shoulder of the retaining sleeve, so that there is clearance between the boss and the first stepped shoulder, a guide taper of the boss of the guide sleeve going forward and just falling into the cavity at 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. 
     
     
         9 . A connector block as claimed in  claim 1 , wherein a center cavity is 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 body at the connection of each channel, the locating sleeve being hollow at the center and having the locating stepped shoulder therein near the center cavity. 
     
     
         10 . A connector block as claimed in  claim 1 , wherein the outside diameter of the sealing ring is tight fitted 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. 
     
     
         11 . A connector block as claimed in  claim 1 , wherein the channel consists of the guide sleeve, the leaf spring, the compression sleeve, the sealing ring, and the locating sleeve.
