Detailed Description

Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

Examples

Referring to fig. 1, a preferred embodiment of an opposite-insertion seven-core deformation probe and management unit for pipeline signal transmission according to the present invention is an opposite-insertion deformation probe and management unit, which comprises a plug 10, a screw sleeve 2 and a socket 1.

The disc-shaped management unit and the deformation probes are both arranged on the plug 10, and the deformation probes are evenly distributed on the management unit. When the plug 10 is connected with the socket 1, the length of the cable of each deformation probe is the same, and the cable is conveniently arranged on the detector. The socket 1 is connected to the detector through a cable, and after the plug 10 and the socket 1 are combined with each other in a plug-in manner, the management unit and the deformation probe are connected to the detector through a cable connected to the socket 1. The screw sleeve 2 is a hollow cylinder and is sleeved on the cable; the socket 1 and the screw sleeve 2 are provided with matched threads, the screw sleeve 2 is matched with the socket 1, and the plug 10 and the socket 1 are tightly pressed and sealed by utilizing the fastening connection of the threads, so that the water pressure of 16MPa can be resisted. The metal parts of the structural part (the shell of the plug 10, the shell of the socket 1 and the thread insert 2) are made of stainless steel instead of common metal. The injection molding process of the plug 10 is changed from cold liquid gravity pouring to high-temperature pressurizing injection molding, so that pouring bubbles can be eliminated, and the surface finish degree is increased; meanwhile, the mould is finely finished, and the injection finish of the plug 10 is improved. In the embodiment, the management unit and the deformation probe have smaller volumes, higher pressure resistance degree and firmer structure, and create better conditions for the transmission of sensor signals

Referring to fig. 2, the top of the cylindrical body of the screw sleeve 2 is milled flat to form a flat surface 3 matched with the bottom of the socket for positioning, and knurling 4 is processed on the outer surface of the screw sleeve 2.

Referring to fig. 6, 4 insertion positioning posts 8 are disposed at the bottom of the socket 1 and arranged in a quadrilateral shape. The diameter of the plug-in positioning column 8 is 1 mm, and the height of the bulge is 1.5 mm. The plug-in positioning columns 8 enable the socket 1 to be more stable.

Referring to fig. 8, an outlet buffer area 11 is disposed at a connection portion between the tail end of the plug 10 and the cable, for improving the problem that the cable is easy to break and wear at the outlet.

Referring to fig. 5 and 7, in order to facilitate the connection between the socket 1 and the plug 10, a first mating positioning indicator 7 is disposed on the socket 1, and a second mating positioning indicator 9 is disposed on the plug 10. The first and second

mating alignment indicators

7, 9 are aligned when the receptacle 1 and plug 10 are in the mated position. Therefore, when the socket 1 and the plug 10 are connected, the first opposite-inserting positioning indication 7 and the second opposite-inserting positioning indication 9 can be aligned firstly, and then the socket 1 and the plug 10 are combined, so that opposite insertion is more convenient, quicker and more accurate.

Referring to fig. 3 and 4, in order to confirm that the screw sleeve 2 is locked in place, a first fastening limit indicator 5 is arranged on the outer side of the screw sleeve 2, and a second fastening limit indicator 6 is arranged on the outer side of the socket 1. After the screw thread between the screw insert 2 and the socket 1 is tightened, the first tightening limit indication 5 and the second tightening limit indication are aligned 6.
