Method and device for fixing radio-frequency coaxial conductor

Abstract

The invention discloses a method and a device for fixing a radio-frequency coaxial conductor. The device is a fixing ring, and an inner surface of the fixing ring is provided with a groove. The method comprises the following steps of: sleeving the fixing ring on an end part of a sheath of the radio-frequency coaxial conductor, performing crimping treatment on the fixing ring to form a multi-surface structure, embedding the sheath and other adjacent parts of the radio-frequency coaxial conductor into the groove on the inner surface of the fixing ring, and changing the fixing mode of the radio-frequency coaxial conductor through the groove of the fixing ring and the crimped multi-surface structure; and connecting a conductor of the radio-frequency coaxial conductor and a shielding layer with a connector, arranging the conductor and the part crimped by the fixing ring on the tail part of the connector, injecting an adhesive, and curing the adhesive to form a colloid so as to fix the conductor with the connector into a whole. The method and the device for fixing the radio-frequency coaxial conductor can reliably fix the radio-frequency coaxial conductor with a fluoroplastic sheath in the colloid, avoid the phenomenon of transmitting an external force to the conductor, and solve the problems of rupture faults of the conductor under the action of the external force and potential rupture hidden trouble.

Description

technical field [0001] The invention relates to a method and a device for fixing a radio frequency coaxial wire, and belongs to the technical field of cable assemblies and wire harness manufacturing. Background technique [0002] In addition to being widely used in RF connector components, RF coaxial wires are also widely used in multi-core cables. In such wire applications, due to space constraints, most connectors are not allowed to be equipped with fixed wire harness devices such as tail clips. The wire is fixed completely by glue. Since the conductor of the RF coaxial wire is very thin and has limited tensile strength, it is necessary to eliminate the external force to avoid the failure of the wire to be broken by the external tensile force. Since the sheath of the RF coaxial wire is made of fluorine-containing plastics, the adhesive force between this type of material and the colloid is very weak, and there is no adhesion, and a large external force can be transmitted ...
