Technical Field

[0001] This invention relates to the field of radio frequency connector technology, and more specifically to an automatic mortise rolling machine for radio frequency coaxial connectors. Background Technology

[0002] Radio frequency (RF) coaxial connectors are generally considered components that are attached to cables or installed on instruments. They are used in the RF transmission circuits of instruments and equipment to electrically connect or disconnect various RF signal transmission lines. They are mechatronic products, and simply put, they mainly act as bridges. RF coaxial connectors can be classified into three types according to their mating method: threaded, push-in, and bayonet. Threaded connectors are the most numerous and widely used. The retaining ring is a key component of threaded connectors.

[0003] In the structure of RF coaxial connectors, the housing is the main retainer in removable denture restorations. It is directly connected to the main equipment and fixed by a threaded connection, serving to retain, stabilize, and support the device.
