Problems solved by technology

Generally, high-voltage connectors do not have airtightness. Even if they are airtight, they are generally realized by rubber sealing. The airtightness is low, and the leakage rate is generally greater than 1.0×10-2Pa.cm3 / s, which is difficult to meet the requirements of new technologies.

Embodiment Construction

[0018] The multi-core high-pressure sealed connector of the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] The multi-core high-pressure sealed connector provided by the present invention is composed of a plug and a socket, the plug is a free end, and the socket is fixedly installed on the mounting panel of the cavity of the sealing system. The plug is composed of a shell 11, a base 12, a socket fitting 13, a locking screw 14, epoxy glue 15, a sleeve 16 and the like. The butt joint of the base of the plug is designed as four boss cylinders 121, one of which is inconsistent with the radial dimension of the other three, which can achieve the purpose of preventing mis-insertion. In this embodiment, the rightmost boss cylinder 121 is slightly large, the other th...

Abstract

The invention provides a multi-core high voltage sealed connector, relating to the field of multi-core high voltage connectors. The multi-core high voltage sealed connector comprises a plug and a socket, wherein fixing devices movably connected with the socket are arranged on two sides of the plug, the base butting end and the base tail end of the plug are of a plurality of independent boss column structures, and a jack fitting connected with a lead is arranged inside each base; the socket comprises two identical ceramic bases, the cylindrical cavities of the ceramic bases matched with base boss columns of the plug are respectively formed inside the butting end and tail end cavities of a socket housing, and pins, the housing and the ceramic bases are connected into a whole by sintered welding of glass insulators. Because the butting end and the tail end of the connector are both convex-shaped, the minimum creepage distance between adjacent contacts after the connector is butted in place is obviously prolonged, the air ionization breakdown between the contacts is effectively prevented, and the high voltage resistance of the connector is realized.

Description

technical field [0001] The invention relates to a multi-core high-voltage connector, in particular to a sealed connector, and belongs to the technical field of electrical connectors. Background technique [0002] As a bridge for signal transmission between internal devices and devices in each system, and between systems, the connector is an indispensable basic device that constitutes the system. Connectors are widely used in aerospace, communications, electronics, automobiles and other fields, among which high-voltage connectors are also widely used as a special category of connectors. [0003] With the rapid development of weapon models and modern science and technology, higher requirements are put forward for high-voltage connectors. The withstand voltage needs to reach tens of thousands of volts or even hundreds of thousands of volts. Some systems also need to meet the requirements of hermetic sealing. Generally, high-voltage connectors do not have airtightness, and even...
