Self-locking fixing device and antenna assembly

Abstract

A self-locking fixing device and an antenna assembly are provided. The self-locking fixing device includes an inner mandrel (10) arranged to include a nail head (110) and a nail rod (111) extending away from the nail head (110), and a bushing (114) arranged to include a nail head bushing (124) and a nail rod bushing (125) extending away from the nail head bushing (124). A sidewall of the nail head bushing (124) is provided with at least two elastic clamping units (121). If the inner mandrel (10) is assembled with the bushing (114), the nail head (110) is located in the nail head bushing (124), the nail rod (111) is located in the nail rod bushing (125), and clamping portions of the elastic clamping units (121) are engaged with an upper surface of the nail head (110) to clamp the nail head (110) in the nail head bushing (124). The self-locking fixing device can achieve a good fixing function. When it is applied to an antenna, the PIM and VSWR performance of the antenna can be enhanced, and the rework rate and manufacturing costs may be reduced.
