PACKING UNIT FOR NUT OF CONNECTOR FOR COAXIAL CABLE, PACKING UNIT FOR CONNECTOR, CONNECTOR AND METHOD OF SEALING SAID CONNECTOR Russian patent published in 2009 - IPC H01R13/52 

FIELD: electricity.

SUBSTANCE: invention relates to electrical engineering and can be used in components of data transmission systems. Connector (10) includes a packing unit (60) for connecting a coaxial cable (12) with an end connection (100) with a male thread. The packing unit includes a bellows-type sealer, with an elastically deformed pipe-shaped case and several sealing surfaces, as well as a non-detachable connection section (65), situated between the external end (58) and rear end (59), which enables axial deformation of the sealer under the effect of a force, directed on the axis. One of the sealing surfaces is meant for holding the corresponding surface of the nut (40) with a female thread. The nut with and attached sealer form a single packing unit. A connector (10) for a coaxial cable includes the case (20) for the connector. One end of the case is attached to the coaxial cable (12). The packing unit is attached to the other end with provision for rotation. The connector can be joined to the end connection with a male thread using the nut of the connector, which has a female thread. The rear end of the sealer is tightly put onto the end connection, and the sealing surface of the sealer can form a tight joint with the projection of the end connection in the axial direction, when the case of the sealer covers the exposed threaded part of the end connection. When screwing the nut onto the end connection, the sealer contracts along the axis, in accordance with different distances between the connector and the projection of the end connection. The sealer can expand, thereby allowing the second sealing surface to get into contact with the smooth surfaces of the end connection with different outer diametre and form a tight joint with it. Versatility of the sealer allows an operator to use the same connector with various end connections with male thread, without fear for poor sealing of the joint or poor connection due to an unsuitable sealer.

EFFECT: increased reliability and wider operational functionality.
