A plugging device for smb connector

Abstract

The invention relates to the field of mechanical tools and discloses a plug-and-pull device for an SMB connector. The plug-and-pull device comprises an outer tube, a spring part arranged in the outer tube and an inner tube, wherein one end of the outer tube is closed, an opening is formed in the other end of the outer tube, one end of the spring part is connected with the closed end of the outer tube, the other end is connected with the upper end of the inner tube, a clamping piece is arranged at the lower end of the inner tube and extends out of the open end of the outer tube, and the clamping piece moving towards the inside of the outer tube is extruded to be gathered together when the inner tube compresses the spring part to move towards the closed end of the outer tube. The plug-and-pull device for the SMB connector can effectively perform meshing and separation between an SMB connector joint and an interface and achieves high-reliability electrical connection.

Description

technical field [0001] The invention relates to the field of mechanical tools, in particular to a plugging device for SMB connectors. Background technique [0002] A radio frequency coaxial connector (RF connector) is generally considered to be a precision connector component mounted on a cable or installed on an instrument for electrical connection or separation of transmission lines. In the development history of RF connectors, miniaturized products such as SMA (Sub-Miniature-A), SMB (Sub-Miniature-B), and SMC (Sub-Miniature-C) have appeared one after another. Push-type connectors for components, small size, good shock resistance, and small footprint, are widely used in communication equipment, instruments and navigation systems with operating frequencies in the range of 0-4GHz. [0003] However, since the SMB connector and the interface are relatively small, the sealing and shock resistance of the SMB connector have put forward high requirements on the plugging and unplu...

AI Technical Summary

Problems solved by technology

According to the different SMB models, the diameter of the SMB connector ranges from 0.9-5.1mm, and the diameter of the more commonly used SMB connector is less than 3mm. One end of the SMB is connected with a soft wire, and the human hand cannot generate insertion or pull force on the SMB connector through the wire. It is difficult to insert the SMB connector into the interface. Experiments show that the engagement and insertion force of the SMB connector generally requires 65N, and the minimum separation force is 9N. Since the outer diameter of the SMB connector and the caliber of the interface are thinner than the fingers of a human hand, the SMB connector joint cannot be realized by hand. Engagement and disengagement from the interface

If only the front end of the SMB connector is slightly inserted into the opening of the interface, it will affect the electrical performance of the SMB and even cause subsequent electrical accidents; if it is necessary to separate the SMB connector and the interface, it is difficult to pull the SMB connector out of the interface by hand connecting wires at the outer end of the connector)
