Problems solved by technology

This kind of problem is difficult to be found in the normal production process, and the proportion is not high. The key is that when testing the performance of this part of the product with micro-gap, most of the performance is good, but in the process of customer use, if experience High temperature (such as reflow soldering, etc.) will cause the gap to increase, the performance will deteriorate, and even the product performance will be seriously poor.
Seriously affected the quality stability of the product and the brand image of the company

Abstract

The invention provides a circulator, which comprises a shell, an in-cavity assembly accommodated in the shell, and a cover plate for packaging the in-cavity assembly in the shell, wherein the shell comprises a bottom wall and a side wall extending upwards from the periphery of the bottom wall, a cavity is defined by the side wall and the bottom wall, the side wall is provided with a plurality of notches from top to bottom, the in-cavity assembly is provided with a plurality of pins used for being connected to a mainboard of communication equipment, the pins straightly extend outwards from thecorresponding notches, a protruding part is formed on the side, facing the in-cavity assembly, of the cover plate, and the protruding part abuts against the top of the in-cavity assembly. According tothe invention, by arranging the protruding part, the sheet materials can be prevented from tilting to form gaps, so that the sheet materials are perfectly attached, and the circulator is reliable inthe using process.

Description

technical field [0001] The invention relates to the technical field of wireless communication equipment, in particular to a circulator. Background technique [0002] In the existing wireless communication system, the transmitter is an important part, which is composed of power amplifier (PA), coupler, circulator, connector, duplexer and antenna, among which the coupler is used for link The related monitoring function, the circulator is used to protect the power amplifier tube, and the connector transmits the output signal to the duplexer. It is a similar design in the wireless field, but with the development of wireless communication, the requirements for miniaturization are getting higher and higher. As an anisotropic element, the circulator plays a very important role in the field of microwave and radio frequency communications. Through its one-way transmission characteristics, it can protect the components in the circuit from damage by useless signals, and also enable th...
