TECHNICAL FIELD

[0001] The utility model relates to cable connector technical field, concretely relates to a soft antenna waterproof structure connector. BACKGROUND

[0002] In the field of underwater signal acquisition, the sealing and reliability of the radio frequency connector directly affect the signal transmission quality and equipment safety. The traditional radio frequency cable connector usually adopts an inner and outer conductor structure (for example, a coaxial cable), and the connection mode is mainly that the inner conductor is welded or plugged with the inner conductor, and the outer conductor is welded or mechanically connected with the outer conductor.

[0003] However, when connecting the traditional connector and some special radio frequency cables (for example, a soft antenna), since the cable only has an inner conductor and does not have an outer conductor, when the inner conductor of the cable is welded with the inner conductor of the connector, and the outer conductor of the connector is not connected, the outer conductor of the connector forms an open cavity due to the lack of a corresponding connection target, and the cavity is directly exposed to the underwater environment. Even if the inner conductor is welded, there is still a gap in the outer conductor area that is not sealed, which becomes the main path for water to penetrate. The unsealed outer conductor cavity can cause internal water accumulation due to capillary action within 24 hours, leading to conductor oxidation, dielectric constant changes and other problems, ultimately resulting in the inability to successfully transmit signals.

[0027] Specifically, the sealing material includes a fixing glue 400, the staff clamps and fixes the connector through the external positioning tool, and then pours the fixing glue 400 into the cavity 103 through the filling machine, so as to fill the cavity 103 between the inner wall of the outer conductor 102 and the outer wall surface of the cable body 200, and ensure the sealing property of the outer conductor 102.

[0028] Further, the sealing material further includes a waterproof glue 500, the fixing glue 400 and the waterproof glue 500 cooperate with each other, the fixing glue 400 is solidified after being filled into the cavity 103 for a certain time, the solidified fixing glue 400 can fix the cable body 200, so that the cable body 200 does not shake in the outer conductor 102, and the stability is improved, the waterproof glue 500 is arranged close to the opening end of the outer conductor 102, so that the waterproof glue 500 can directly contact water, because the waterproof glue 500 has strong corrosion resistance, the waterproof glue 500 will not be eroded and corroded by water, the sealing property is further improved, and the overall service life is improved.
