Positioning device for phase shifter welding and method for positioning phase shifter by using positioning device

Abstract

The invention relates to a positioning device for phase shifter welding and a method for positioning a phase shifter by using the positioning device. The positioning device comprises a power dividingplate positioning bottom plate and a phase shifter limiting plate which are oppositely arranged. A limiting hole used for limiting the phase shifter is formed in the phase shifter limiting plate; thephase shifter is located in the limiting hole; the surface, facing the phase shifter limiting plate, of the power dividing plate positioning bottom plate forms a bearing surface used for bearing a power dividing plate; and a first positioning column used for being connected with a first positioning hole in the power dividing plate in a matched mode is arranged on the power dividing plate positioning bottom plate. The positioning device for phase shifter welding further comprises a pressing structure arranged on the phase shifter limiting plate, wherein the pressing structure is used for pressing the phase shifter on the power dividing plate, so that the bottom face of the cavity wall of the phase shifter can be attached to a first bonding pad on the face, facing the phase shifter, of the power dividing plate, a positioning effect on the phase shifter is improved, and gaps generated by contact between the phase shifter and the power dividing plate can be effectively eliminated.

Description

technical field

[0001] The present disclosure relates to the technical field of phase shifter welding, in particular to a positioning device for phase shifter welding and a method for positioning the phase shifter. Background technique

[0002] Phase shifters are the core components of base station antennas. In specific use, it is necessary to weld and fix the bottom surface of the cavity wall of the phase shifter and the pad of the power distribution board. Before welding, it is necessary to position the phase shifter and the power distribution board. Position on the power splitter board, then solder.

[0003] However, manual positioning will lead to poor positioning effect between the phase shifter and the power distribution board, resulting in gaps between the bottom surface of the cavity wall of the phase shifter and the welding pad of the power distribution board, which will affect the welding quality at the solder joints.
