High pressure cable head connector

A sealing cable connector device for high pressure applications, the sealing cable connector comprising a first connector part and a second connector part including an axial cable channel for allowing a cable to extend, the cable having a cross section comparable to the dimensions of the channel, the first connector part having a cylindrical connector channel with an outer wall having a larger cross section than the cable channel and with a radially oriented inner surface, and the second connector part being adapted to be introduced into the connector channel, the second connector part having a radially oriented front end surface, wherein a cavity is defined between the inner surface and the front end, the cavity being coaxially oriented around the cable channel, the first and second connector parts including locking means being adapted to applying an axial force and lock the parts together after connecting;

• wherein at least one spring bevel ring is positioned at the inner surface in the cavity having radial dimensions corresponding to the radial dimensions of the cavity between the cable channel and the radially outer walls of the connector channel, wherein the at least one spring bevel ring has a radial cross section having an essentially rectangular shape with rounded corners, and having a predetermined angle relative to the longitudinal axis of the cable;
• wherein at the application of the axial force between the first and second connector parts, the at least one spring bevel ring is tilted by the force between the inner surface and the end surface and thus forced in the radial direction both into the cavity wall and into the cable channel, so as to provide a sealing interaction both between the at least one spring bevel ring and the cavity wall and between the at least one spring bevel ring and the cable;
• and
• wherein the at least one spring bevel ring is adapted to, when compressed, to interact with the front end of at least one of the second connector and inner surface of the first connector part and thus act like an energized spring that exerts high contact stress into the cavity wall and into the cable channel to compensate thermal expansion of the parts.
