Problems solved by technology

In particular, due to the use of polyethylene and polytetrafluoroethylene (PTFE) to manufacture the two parts of the insulation, such connectors are not suitable for dissipating high power at heights, more specifically under vacuum conditions

Embodiment Construction

[0078] figure 1 An example of a coaxial connector, for example a TNC-type connector, with an axis X, generally indicated with reference numeral 1, is shown. This coaxial connector 1 in this example comprises a main body 2 made in one piece and a central contact 3 fitted in the main body 2 with an insulating member 4 interposed between the main body 2 and the central contact 3 . A cylindrical channel 7 is formed in the insulator 4 to accommodate a central contact 3 which, in the example shown, has a substantially cylindrical outer shape.

[0079] In the example described, the coaxial connector 1 also includes a cap 5 fitted to the front of the body 2 and a sleeve 6 fitted to the rear of the body 2 . In the example described, the cap 5 defines the front of the connector 1 adapted to be coupled to a complementary coaxial connector, while the sleeve 6 defines the front of the connector 1 for fitting on a coaxial cable 8 . rear.

[0080] Such as figure 1 As shown, a coaxial cab...

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...
