Description

Technical Field

[0001] The present invention relates to the technical field of radio frequency coaxial connectors, and in particular to a device for automatically and quickly plugging and unplugging radio frequency plugs in batches. Background Art

[0002] Coaxial RF cables are a staple in the RF and microwave industries. This is because all important equipment, from smartphones and laptops used in daily life to radars and global positioning systems (GPS) in the military and aerospace fields, requires such cables for connection. There are many types of coaxial RF connectors at both ends of coaxial RF cables, such as SMA, SMPM, EBC, BNC, etc., depending on different electrical and mechanical performance standards. In many communication devices, each device usually needs to be connected to dozens or hundreds of coaxial cables, which also requires this in pre-shipment testing of the product.

[0003] Most existing solutions use manual connection. Even with manual fixture connection, the force of plugging and unplugging hundreds of connectors at the same time does not have strong operability. These solutions are time-consuming and labor-intensive, and errors are inevitable. The connection of hundreds of connectors in batches needs to consider multiple position errors and dimensional errors, making it difficult to ensure connection accuracy. Another common connection form is single-sided connector connection, but some require plugging and unplugging on both sides of the product at the same time, which is a big challenge.
