Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of connector, concretely is a kind of radio frequency coaxial millimeter wave cable connector. BACKGROUND

[0002] The millimeter wave cable connector on the market at present is mainly divided into threaded screw connection (for example 2.92mm series) and elastic plug-in contact connection (for example SMP series), wherein threaded connection focuses on the stability of product use, and elastic plug-in contact connection focuses on the quick convenience of product use, user can select one relatively appropriate scheme in the above two schemes according to the specific needs of own product, and further consider the specification and adaptation of radio frequency coaxial cable.

[0003] Defects and deficiencies of prior art:

[0004] 1. The above two schemes of the prior art cannot simultaneously consider the advantages of connection stability and quick plug-in, for example, the cumulative time of single-side male and female end insertion and extraction of the millimeter wave connector of threaded connection is about 10s, general radio frequency cable assembly needs to be connected to the connector on both sides, and the total time is about 20s, for the environment needing repeated disassembly and assembly (such as production debugging, test, etc.), especially for large-scale cable assembly joints needing repeated disassembly and assembly, the labor cost is relatively high.

[0005] 2. The connector of elastic plug-in contact connection has the advantage of quick plug-in (the cumulative time of single-side male and female insertion and extraction is about 5s), but its disadvantage is also obvious, the cable joint after insertion cannot be subjected to axial pull-off force and radial thrust, and external force applied by the environment can cause instability of insertion, the use environment of such cable joint needs to be relatively stable, or another safety fixing structure is additionally provided outside the joint, and the millimeter wave joint of the type cannot bear some relatively thick armored cables due to the standard size, further limiting the use environment.

[0006] In summary, there is no millimeter wave cable connector on the market at present that can simultaneously meet the connection reliability and quick plug-in characteristics, reduce the labor time cost required for joint insertion and extraction, meet the stability of connection, and also consider the use space of connector joint (i.e. the overall size of connector) and the use of highest frequency (up to millimeter wave level and above).
