A connection method and connection mechanism of a stainless steel hose and a radio frequency connector

Abstract

The invention provides a connection method between a stainless steel hose and a radio frequency connector, comprising the following steps: putting the stainless steel hose on the non-slip thread of the connecting nut; Align the lock step with the flat position of the connecting nut, press the pressure ring so that the end face of the inner lock step fits the limit flange, the end face of the inner hole of the pressure ring exceeds the end face of the connecting thread; flatten at the position corresponding to the anti-slip thread on the outer ring of the pressure ring; Pass the wire at the tail of the RF connector through the stepped hole of the connecting nut, and screw it into the tail of the RF connector through the connecting thread. The invention provides a connection method and a connection mechanism between a stainless steel hose and a radio frequency connector. The stainless steel hose is fixed by a flattening structure, which is firm and reliable. In the process, a good positioning is formed on the pressure ring, which avoids adverse situations such as force deviation, rotation, and retreat of the pressure ring, and ensures the quality of the flattening.

Description

technical field [0001] The invention belongs to the technical field of connectors, and in particular relates to a connection method and a connection mechanism of a stainless steel hose and a radio frequency connector. Background technique [0002] Various coaxial cable assemblies are often used in test equipment. Due to the test environment, test equipment or probes need to be moved frequently, and fixed buried wire protection cannot be carried out. Coaxial cable assemblies are placed directly on the ground. At the same time, in order to ensure that the cable assembly To ensure that the cable is intact and working normally in harsh and harsh environments, it is necessary to cover the cable with a stainless steel hose for protection, and in order to meet the electromagnetic compatibility requirements of the cable assembly, the stainless steel hose needs to be connected to the end of the RF connector Perform reliable connection to ensure its reliability. For example, the Chine...

[0002] Various coaxial cable assemblies are often used in test equipment. Due to the test environment, test equipment or probes need to be moved frequently, and fixed buried wire protection cannot be carried out. Coaxial cable assemblies are placed directly on the ground. At the same time, in order to ensure that the cable assembly To ensure that the cable is intact and working normally in harsher and harsher environments, a stainless steel hose needs to be placed outside the cable for protection, and in order to meet the electromagnetic compatibility requirements of the cable assembly, the stainless steel hose needs to be connected to the end of the RF connector Perform reliable connection to ensure its reliability. For example, the Chinese patent whose publication number is CN104092067A provides a fixed structure of a stainless steel hose armor of a coaxial cable and a radio frequency connector, including the armor arranged on the cable. The armor is a stainless steel hose The sleeve is screwed on the connector, and the characteristic is that the sleeve is provided with external thread and the shaft shoulder or the inner wall is provided with a spiral flange; the groove of the armor is screwed into the spring by the sleeve of the shaft shoulder and the The connector is screwed or the groove of the armor is screwed into the sleeve of the helical flange and the connector is screwed. This structure is easy to disassemble. However, during use, the armor is always rotated in the direction of screwing out by external force. There is a risk of the armor coming out, causing signal shielding failure or even damage to the cable assembly
