Abstract

The present invention relates to a very-large-power connector, concretely a coaxial connector comprising: a body; and a central contact mounted in the body with interposition of insulation; wherein the insulation comprises at least two distinct portions: a) that are separated by an interface presenting at least a fraction that extends obliquely relative to the axis of the connector; and / or b) that are made of different dielectric materials; the connector being configured to withstand breakdown phenomena at altitude, in particular under vacuum conditions.

Description

technical field

[0001] The invention relates to a coaxial connector.

[0002] The present invention relates more particularly to a coaxial connector for use in the aerospace field, where such a connector is advantageously capable of withstanding high power at heights, more particularly under vacuum conditions. The term "at altitude" is understood to mean an altitude greater than 30,000 feet. In the context of the present invention, vacuum conditions are at least a substantial vacuum, i.e. 10 5 The condition of Pascal (Pa) goes down to the vacuum of space, which is 1.33×10 -8 Pa conditions. The term "high power" refers to powers of approximately 400 watts (W) at 1 or 2 gigahertz (GHz), 300 W at 7 GHz, and several hundred watts at 18 GHz. The connector can withstand power greater than 100W, for example. Background technique

[0003] The higher the frequency of the signal, the greater the heat that needs to be dissipated. In order to reduce heat generation, it is known to...
