Embodiment

[0029] Example: such as Figure 1 to Figure 4 As shown, a sealing structure of an underwater electrical connector, the electrical connector includes a plug 1 with a built-in terminal and a socket 2 with a built-in terminal, and both the plug 1 and the socket 2 are provided with conductive cables to ensure electrical The electrical continuity of the connector during use.

[0030] The plug 1 is provided with pins 11 that are electrically connected to the terminals in the plug 1. The pins 11 can be set in multiples according to the number of cables arranged in the plug 1, and the multiple pins are insulated from each other. This enables the electrical connector to be plugged and unplugged underwater without load, ensuring safety during use.

[0031] The jack 21 is formed on the socket 2 to match the above-mentioned pin 11. When the plug 1 is plugged into the socket 2, the pin 11 is in electrical contact with the terminal provided in the jack 21 to realize electrical connectivity...

Abstract

The invention relates to a plug, a socket, and a sealing structure of an underwater electrical connector. The sealing structure comprises a plug and a socket that are plugged together. Outsides of pins are coated with sealing bodies partially; and exposed contact bodies are formed at the end portions of the pins and are arranged outside the pin-coated sealing bodies. Inner walls of jacks are coated with sealing bodies. In a plugging state of the pins and the jacks, the exposed contact bodies of the pins are in contact with contact bodies arranged inside the jacks electrically; and the pin-coated sealing bodies and jack-coated sealing bodies are in an interference fit mode. The sealing structure that is simple and reliable can be manufactured conveniently and has the good sealing performance. Because of the independence of all pins coated by pin sealing bodies, underwater plugging of an electrical connector is realized on the condition of having no load and replacement and maintenance become convenient. In addition, the invention also aims at providing a plug having advantages of simple and reliable structure and good sealing performance and aims at providing a socket having the same advantages as the plug.

Description

technical field [0001] The invention relates to the technical field of underwater cable connection equipment, in particular to plugs, sockets and sealing structures of underwater electrical connectors. Background technique [0002] Underwater electrical connectors are mainly aimed at various underwater operations. They are the best equipment for underwater power distribution, control and electrical protection. During use, underwater electrical connectors must not only have sufficient high-voltage resistance, but also need to have good To ensure the sealing performance of the product, it is necessary to ensure that after the pin and the socket are mated, the product will not fail due to problems such as short circuit between contact pairs, between contact pairs and seawater, and insulation performance reduction due to poor sealing. [0003] In recent years, with the accelerated construction of underwater operations, the application of underwater electrical connectors has beco...
