The conductive stopper hole 224 has a function of separating the conductive terminal 31 and the insulating terminal 32.
The end of the outer side wall of the cable terminal plug 2 for connecting the cable connection 3 is provided with a threaded section 225, and the threaded section 225 is sleeved with a jacket 226 for pressing the insulating end 32 of the cable connection 3 to the inner side of the movable sleeve 231. When the jacket 226 is rotated in the threaded section 225, the jacket 226 presses the insulating end 32 toward the inner side of the movable sleeve 231, so that the cable connection 3 is prevented from falling off from the inside of the movable sleeve 231, and the clamping is firm.
As a preferred embodiment: the collet 226 includes a mounting barrel 227 having an inner wall that mates with the threaded section 225, and the end of the mounting barrel 227 remote from the cable termination plug 2 is provided with a plurality of annular arrays of clips 228 at the end of the mounting barrel 227. And the mounting barrel 227 is threaded with a locking sleeve 229 that can be pressed proximally against the outer wall of the distal end of the clip 228.
Preferably, the thickness of the clip 228 increases from a proximal end near the mounting barrel 227 to a distal end away from the mounting barrel 227, thereby ensuring that the clip 228 gradually contracts as the outer sidewalls of the clip 228 are compressed.
And the end of the clip 228 adjacent the mounting cylinder 227 is provided with a sealing ring 220. The sealing property of the connection portion of the cable connection 3 can be enhanced.
When the device is installed, the method comprises the following steps:
the method comprises the following steps: peeling off the end part of the cable connection 3 to form a conductive end 31 with a certain length, then sleeving the cable connection 3 in the movable sleeve 231, and enabling the boundary part of the insulating end 32 and the conductive end 31 to be pressed on the conductive limiting hole 224 to complete connection;
step two: then, the movable sleeve 231 is rotated to make the positioning guide groove 222 on the movable sleeve 231 correspond to the positioning guide edge 237 on the movable part 23, and the movable sleeve 231 is pushed to the side end of the plug connecting part 21 along the movable part 23;
step three: applying an external force to the clamping portion 22 for clamping the cable connection 3, so that the clamping portion 22 passes through the elastic limiting arc 234 and enters the plug connecting portion 21, and is limited and fixed;
step four: tightening the locking sleeve 229 toward the end near the connection hub 1 causes the locking sleeve 229 to press proximally against the outer walls of the distal ends of the clips 228. As the inner walls of clip 228 become progressively thicker from a proximal end near mounting barrel 227 to a distal end away from mounting barrel 227, the distal ends of clip 228 become progressively tighter at the outer wall of insulating end 32 and eventually grip cable connection 3.
