Connector with torque force

Abstract

The invention relates to a radio frequency coaxial connector, in particular to an SMA connector provided with torque force. The connector provided with the torque force is an important constituent part of a small size antenna of equipment such as a wireless public telephone and a wireless router and plays a decisive role in signal reception function of the equipment. Aiming at the problem that torque force of an existing SMA connector gradually lose efficacy in a using process of the antenna, the invention discloses the connector provided with the torque force. The connector provided with the torque force comprises a contact pin, a big insulator, a small insulator, a clamping ring, a wire thread insert and a rubber washer. The connector provided with the torque force is characterized in that a cable core penetrates through the small insulator and is welded in a contact pin hole, the contact pin 1 is pressed in the big insulator, the rubber washer is installed on a protruding step inside the wire thread insert, the clamping ring is arranged in a groove formed in the outer surface of an outer shell in a clamping mode, barbs are arranged inside the outer shell, the clamping ring is an elastic component, and the wire thread insert is arranged on the outer shell in a clamping mode as long as the elastic clamping ring is tightened. The connector provided with the torque force has low probability of being affected by external factors and generating changes, can effectively ensure the torque force for a long time when the wire thread insert rotates, can be clamped in an internal groove of the wire thread insert at the same time, and prevents the wire thread insert from falling off.

Description

Technical field

[0001] The invention relates to a radio frequency coaxial connector, in particular to an SMA connector with torsion force, which is an important component of small antennas of wireless public phones, wireless routers and other equipment, and plays a decisive role in the signal receiving function of the equipment. Background technique At present, the small antennas of wireless public phones, wireless routers and other equipment are in actual use. Over time, due to the aging of the rubber gasket of the connector in the antenna, the entire antenna will gradually lose its torsion effect and cannot effectively stay at the user specified At the same time, the antenna will fall off due to the loosening of the screw sleeve. This leads to increased maintenance costs of the equipment. Summary of the invention 1. Technical problems to be solved: The existing SMA connector has the problem of gradual torsion failure during the use of the antenna system. 2. Technical...
