Abstract

The invention provides a buckling and pressing inner screw cap type circulator. The circulator comprises a shell and a cover plate, wherein the shell is a semi-open cavity; a plurality of notches areformed in the side wall of the shell at intervals, a groove is formed in the inner side wall of the shell, the two ends of the groove are communicated with the two adjacent notches in the shell, a clamping block which extends outwards and is matched with the groove is arranged on the outer edge of the cover plate, a working assembly is contained in the shell, and the cover plate is pressed above the working assembly in a covering mode. According to the invention, the cover plate and the shell are connected through the pressing fit of the clamping block and the groove; accurate positioning of the cover plate and the shell does not need to be considered, the assembling operation of assembling personnel is simplified, the assembling efficiency is improved, batch production can be achieved more quickly, and the percent of pass is high; meanwhile, internal threads are prevented from being machined in an inner cavity of the shell, the shell can be formed through punching, and the machining difficulty and the machining cost of the shell are reduced.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a crimped inner screw cap type circulator. Background technique [0002] In the existing circulators and isolators, the housing is an indispensable part, and the housing undertakes functions such as mechanical support, packaging, magnetic conduction and conduction. A good packaging or assembly method can achieve a small external magnetic resistance, so that the circulator or isolator can work normally with a small permanent magnet. [0003] The existing circulator assembly generally adopts a screw cap structure, the shell and the cover plate are assembled in the form of thread locking, and the shell is machined, and the inner edge of the shell and the outer edge of the cover plate need to be processed with threads. Shells with internal threads are difficult to process, and the processing cost is high, and the thread requirements must be considered, so ...
