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 inconsisten...

Embodiment 1

[0035] Such as figure 1 , figure 2 , image 3 As shown, the watertight connector without a skeleton structure includes a plug 1 and a socket 2. The socket 2 includes an insulating body A3, a set of pins 5, and at least one positioning pin 6. The terminal of the pin 5 is connected with a polyfluorine sheath core Wire 12, each wire is connected to a conductive pin 5, and the other end of the core wire 12 is connected to the electrical equipment in the deep-sea pressure chamber. For the transmission of power and signals, the pin 5, the positioning pin 6 and the polyfluorine sheathed core wire 12 are integrally formed with the insulating body A3 through injection vulcanization;

[0036] The plug 1 includes an insulating body B15, a set of jacks 7 matching the pins 5 and a positioning pin jack 14 matching the positioning pins 6, the terminals of the jacks 7 are connected with a watertight cable 16, the jacks 7, the positioning pin sockets The hole 14 and the watertight cable 16...

Embodiment 2

[0042] Such as figure 2 , Figure 4 As shown, the watertight connector without a skeleton structure includes a plug 1 and a socket 2. The socket 2 includes an insulating body A3, a set of pins 5, and at least one positioning pin 6. The terminal of the pin 5 is connected with a polyfluorine sheath core Line 12, each wire is connected to a pin 5, and the other end of the core wire 12 is connected to the electrical equipment in the deep-sea pressure chamber. The signal transmission function, the pin 5, the positioning pin 6 and the polyfluorine sheath core wire 12, are integrally formed with the insulating main body A3 through injection vulcanization;

[0043] The plug 1 includes an insulating body B15, a set of jacks 7 matching the pins 5 and a positioning pin jack 14 matching the positioning pins 6, the terminals of the jacks 7 are connected with a watertight cable 16, the jacks 7, the positioning pin sockets The hole 14 and the watertight cable 16 are integrally formed with...

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...
