Description

Technical Field

[0001] The present invention relates to the technical field of radio frequency coaxial connectors, and in particular to a quick positioning and automatic closing mechanism for a needle-type inner conductor. Background Art

[0002] The contact jack of the RF coaxial connector is a key part of electronic components. Most electronic contact failures are caused by improper closing process methods of the slotted jack contacts. Improper closing will cause problems such as unstable insertion and extraction force, eccentric appearance, and poor consistency of outer diameter dimensions. Currently, the jack closing technology is manually performed with tweezers or closing pliers. The work is highly repetitive, labor-intensive, and has low production efficiency. In addition, this closing technology cannot accurately control the closing of the jack, resulting in uneven deformation at the closing, poor closing accuracy, and difficulty in ensuring closing consistency. Therefore, seeking the best jack closing process method is the key to ensuring the electrical performance of the product. Summary of the Invention
