Embodiment Construction

[0065] figure 1 , Figures 1A to 1C as well as figure 2 Two different examples of coaxial power connection systems according to the prior art are involved. These figure 1 , Figures 1A to 1C as well as figure 2 It has already been discussed above, so it will not be further discussed below.

[0066] In the following, the invention is described with reference to a 7 / 16 type RF cord and by way of example and illustration with a bayonet type quick locking device. However, the invention can be applied to any type of power RF line.

[0067] image 3 and 3A represent an example of a coaxial power connection system 1 according to the invention, with the plug 2 and the socket 3 in an interconnected and locked configuration. In this configuration, the connection system 1 extends along the longitudinal axis X. As shown in FIG. This connection system 1 comprises, respectively, a plug 2, a socket 3 and a manual locking device 4 suitable for when the plug 2 and the socket 3 are i...

Abstract

A coaxial power connection system comprises: a plug, a socket, and a bayonet-type locking device.The plug and the socket each comprises: a central contact, a ground contact. The bayonet-type locking device is suitable for mechanically locking the plug to the socket, in which the bayonet locking device is suitable for providing and allowing an axial operating play to remain between ground contacts on the axis X. Once the locking is done, the connection between ground contacts is produced by the radial bearing of the ground contact against the interior of the other ground contact.The system also comprises a spring, arranged around the ground contact,and the spring is compressed by the bearing of the other ground contact when the plug is locked to the socket,then maintains compressed once the locking is done so as to keep the plug and the socket locked together with the axial operating play between ground contacts.

Description

technical field [0001] The present invention relates to a coaxial power connection system, in particular said system is intended for the transmission of radio frequency (RF) power signals. [0002] The application particularly targeted by the invention is the connection of units of telecommunication equipment in the wireless communication market, such as Base Transceiver Stations BTS and RRU / RRH (Remote Radio Unit / Remote Radio Head). [0003] The invention also generally relates to connection systems in the medical field, the industrial field, the aeronautical or transport field and the aerospace field. [0004] More specifically, the present invention aims at proposing a coaxial type power connection system whose electrical and mechanical RF performance levels are controlled and stable over time, in particular, said performance levels have Low contact resistance and low intermodulation level. Background technique [0005] The market, as well as the prior art, have charact...
