Embodiment

[0028] This example Figure 1 to Figure 12 As shown, the present invention will be described in detail by taking the sealing and insulating structure for a high-current female joint connecting three wires as an example.

[0029] In this example, three electrified rings 2 are used, and the three electrified rings 2 are evenly distributed along the axial direction of the outer tube 1. Both ends of the three electrified rings 2 are separated by a sealing insulating ring 3, and the electrified rings above the top electrified ring 2 and the bottom electrified ring 2 below is also provided with sealing insulation ring 3. A trapezoidal ring groove 14 is crimped between the live ring 2 of metal structure and the sealing insulating ring 3 of non-metal structure to form an integral sealing structure. Each electrified ring 2 is provided with a connecting ear 4 for connecting to the wire 6, and the connecting ear 4 on the three electrified rings 2 is arranged in a staggered manner, and t...

Abstract

The invention discloses a sealing insulation structure for an underground high-current female joint, wherein the sealing insulation structure comprises an outer pipe (1), a group of electrified rings(2) which are uniformly distributed along the axial direction are arranged in the outer pipe, and sealing insulation rings (3) are arranged at the upper end and the lower end of each electrified ring;a connecting lug (4) is arranged on one side of each electrified ring, and the connecting lugs on one group of electrified rings are arranged in a triangular shape; each connecting lug is provided with a wiring hole (5); a wire (6) is inserted into each wiring hole, and the wires and the wiring holes are welded after being pressure-welded; and the other end of the wire connected with each electrified ring penetrates out of a wire penetrating hole (8) of a corresponding fan-shaped insulating plate (7) and then is led out of the top of the outer pipe. A plurality of fan-shaped insulating platesare spliced into a cylinder structure, so that the machinability, the mounting operability and the reliability of a product are improved; key positions such as a joint are filled with insulating glue, so that the insulativity is further improved; the outer pipe is connected with an upper body through hanging nails, the wall thickness of the outer pipe can be greatly reduced, and enough space is reserved for the fan-shaped insulating plates.

Description

technical field [0001] The invention relates to a sealing and insulating structure for an underground high-current female joint, belonging to the technical field of downhole instrument structures. Background technique [0002] In the fields of oil and gas field or coal mine exploration, geothermal logging, and marine survey, processes such as downhole wet docking are often used to supply power to downhole instruments for construction operations such as well logging, perforating, and coring. Downhole live wet joints need to solve the problems of reliable power supply and long-term sealing and insulation. The existing multi-core wet joint is limited by various factors such as the outer diameter of the instrument and the outer diameter of the wire, the structure is relatively complicated, and the reliability is not satisfactory. Therefore there are still deficiencies in the prior art and need to be further improved. Contents of the invention [0003] The object of the prese...
