Two-body-type welding structure of inner conductors of radio-frequency coaxial connector

Abstract

The invention discloses a two-body-type welding structure of inner conductors of a radio-frequency coaxial connector. A jack is formed in a first inner conductor; an inserting column, matched with the jack, is arranged on a second inner conductor; the first inner conductor and the second inner conductor are arranged in an inserting-connecting manner; a stage is arranged between the second inner conductor and the inserting column; and a lug boss is arranged on the inserting column. The connector is set into two sections, one stage is arranged on one section, and the two sections of the connector are connected to form a groove; in design, the area of the groove is equivalent to the section area of selected soldering tin wires; and in installation, a soldering tin ring is placed in the groove and heated on an inductive type resistance welding machine to enable the soldering tin to be melted and solidified, so that the split type inner conductors form an integrated structure.

Description

Technical field [0001] The invention relates to a radio frequency coaxial connector, in particular to a two-body welding structure of the inner conductor of the radio frequency coaxial connector. Background technique [0002] Currently, the inner conductors used in radio frequency connectors such as filters and duplexers are relatively long, for reasons of ease of design or cost saving. When the inner conductor is relatively long, and the customer's three dielectric requirements are high, and the air tightness is good, a welding structure is required. When the inner conductor of the RF connector used for the filter / duplexer is longer, consider saving costs: for example, the inner conductor of the high-demand connector, especially the socket end, requires a better material, such as beryllium copper, with high performance Phosphor copper, etc., these materials are very expensive, so the inner conductor is usually made into two sections in the design, beryllium copper is used for t...

AI Technical Summary

Problems solved by technology

[0003] In the design of relatively long inner conductors, threaded connections or general welded connections are usually used. When threaded connections are used, they are easy to loosen during vibration, impact, and high and low temperature changes, resulting in poor contact and affecting performance. Welded connections can avoid these situations. , but the appearance of the general solder connection is ugly
