Problems solved by technology

When the upper limit frequency is increased to the X-band or Ku-band (12.4GHz~18.0GHz), the length of the cable assembly is controlled by mechanical trimming tolerances, which is far from meeting the requirements of precise phase matching.
During use, the user needs to cut, assemble, test, etc. the cable / connector assembly. For the phase accuracy matching of multiple sets of cables, this process requires a lot of time, manpower and material resources

Abstract

The invention discloses a phase-adjustable radio frequency coaxial connector which comprises an outer conductor (1) and an inner conductor (7), wherein the inner conductor (7) is arranged in a dielectric body (6); the dielectric body (6) is arranged in the outer conductor (1); a transfer needle (8) is connected with a core wire of a cable (10); the inner conductor (7) and the transfer needle (8) form an inner conductor sliding contact pair; an adjusting turnbuckle (3) is arranged at the tail end of a connector; the adjusting turnbuckle (3) is respectively connected with the outer conductor (1) and a sleeve (5); the rotation of the turnbuckle (3) is adjusted to drive the inner conductor sliding contact pair to telescope and the sleeve (5) to move in the outer conductor (1) to adjust the length of the connector; and a locking screw (4) locks the adjusting turnbuckle (3), the outer conductor (1) and the sleeve (5). The invention can simplify the phase matching process, improve the matching accuracy and reduce the production cost, and has small volume, convenient adjustment, large adjustment range, high accuracy, low insertion loss, low voltage standing wave ratio and high stability.

Description

technical field [0001] The invention relates to a radio frequency connector, in particular to a phase-adjustable radio frequency coaxial connector. Background technique [0002] In the phase matching system of phased array radar and electronic countermeasures, the cable / connector assembly is required to have precise electrical length. In the case of lower frequency bands and phase requirements that are not too strict, strictly controlling the length of the cable assembly to meet certain tolerance requirements can also achieve the purpose. When the upper limit frequency is increased to the X-band or Ku-band (12.4GHz~18.0GHz), the length of the cable assembly is controlled by the method of mechanical trimming tolerance, which is far from meeting the requirements of precise phase matching. During use, the user needs to cut, assemble, test, etc. the cable / connector assembly. For the phase accuracy matching of multiple sets of cables, this process requires a lot of time, manpowe...
