Watertight connector with skeleton-free structure

Abstract

The invention discloses a watertight connector with a skeleton-free structure. The watertight connector with the skeleton-free structure comprises a plug (1) and a receptacle (2). The receptacle (2) comprises an insulating main body A (3), a group of pins (5) and at least one positioning pin (6), wherein a connecting terminal (5) of each pin (5) is connected with a polyfluoride sheath core wire (12); and the pins (5), the positioning pin (6), the polyfluoride sheath core wires (12) and the insulating main body A (3) form an integrated structure. The plug (1) comprises an insulating main body B (15), a group of jacks (7) matched with the pins (5), and a positioning pin jack (14) matched with the positioning pin (6), wherein a connecting terminal of each jack (7) is connected with a watertight cable (16); and the jacks (7), the positioning pin jack (14), the watertight cables (16) and the insulating main body B (15) form an integrated structure. The watertight connector has the advantages of simple structure, high processibility, small volume, convenience for plugging and unplugging, high insulativity, contact reliability and long plugging and unplugging service life.

Description

technical field [0001] The invention relates to the technical fields of ocean and oil and gas, in particular to a skeletonless structure watertight connector used for power and signal transmission of deep sea exploration, oil and gas drilling and operation technical equipment. Background technique [0002] At present, there is no skeleton structure watertight connector used for power transmission and signal transmission of electrical equipment in deep sea exploration, oil and gas drilling and operation in China. Skeletonless structure type used in deep sea exploration, oil and gas drilling and operation Watertight connectors mainly rely on foreign imports, which not only have a long order cycle and are expensive, but also encounter technical blockade and embargoes from developed countries. [0003] In order to improve the reliability of the electrical contact performance of each contact pair of the domestic existing skeleton structure type watertight connector, an insulating...

AI Technical Summary

Problems solved by technology

[0005] The existing skeleton type watertight connectors in China have complex structure, poor manufacturability, high processing cost, unreliable watertight performance, unstable electrical contact performance, and short plug-in life

The watertight connectors currently used are all of the skeleton structure type. Since the main body of the socket and plug is vulcanized by rubber injection, and the skeleton is injection molded by insulating material, the production of the mold and the skeleton will increase the production cost virtually. Moreover, the hot and cold deformation of the frame and rubber under the influence of the vulcanization temperature is inconsistent, and the bonding performance between the positioning frame and the rubber is extremely poor, so that the positioning frame and the rubber are prone to degumming and separation during glue injection and vulcanization, so that the socket cannot be used after cooling. To achieve the expected effect, when the environmental pressure changes or is impacted by external objects during actual use, the straightness and position of the pins may be permanently deformed or broken, which will increase the contact resistance of the connector or the circuit The broken circuit fails, and the design of the pin collar groove is also the Achilles heel that makes the pin break under force
