The end of described notch is the circular hole perpendicular to tube wall, for the location after crossover sub and American cable branch box grafting.
Described copper sheathing is that solid cylinder processes, and all there is the step-shaped blind hole comprising two sections at the two ends of its axial centre, and the outer sector hole footpath of two blind holes is all greater than inner segment aperture; Wherein the outer section of one end blind hole has the internal thread that upper external screw thread nested with described copper mates, and the inner segment of other end blind hole has the internal thread mated with the screwed joint of European cable branch box, for being connected with it.
The internal thread that the inner that described plastic. buffer overlaps axial center hole has outer wall external screw thread nested with described copper to mate, be threaded connection between the two, the nested external thread section length of copper is greater than the internal thread segment length of plastic. buffer cover, and it stretches out, and internal thread segment of plastic. buffer cover is outer to be threaded with described copper sheathing.
There is the guiding step of convex the middle part of described insulation crust length direction, the holddown groove with annular is had outside one end of its corresponding plastic. buffer cover, between its holddown groove and guiding step, the profile of section is the taper shape of flaring, and size is mated with the connecting hole size of American cable branch box knuckle joint.
Operation principle of the present invention is as follows: an end structure of this crossover sub and the structure matching of American cable branch box knuckle joint, the inserted link of knuckle joint blocks by the elastic card claw nested by copper, crossover sub and knuckle joint are firmly fixed with coordinating of knuckle joint endoporus by the holddown groove of insulation crust front end and guiding step, the alignment pin finally by transverse direction is located; Its other end mates with the screw-in bolt arrangement of European cable branch box, is fixed with the copper sheathing of band internal thread hole, is directly screwed in the screwed hole of copper sheathing by the screwed joint of European cable branch box during use in the endoporus of insulation crust.
The present invention adopts plug-in structure by one end, and the other end adopts screw-in bolt arrangement, and a joint realizes two kinds of linkage functions, and operation tool is simplified, and operating process simplifies, and use manpower and material resources sparingly cost, increases work efficiency.
