Radio frequency switch

Abstract

The invention provides a radio frequency switch which comprises a first insulator, a second insulator, a static terminal, a moving terminal, an upper shell and a lower shell, wherein the first insulator and the second insulator are matched in the vertical direction, the static terminal and the moving terminal are clamped between the first insulator and the second insulator, and the upper shell andthe lower shell are fixedly clamped outside the first insulator and the second insulator respectively and fixedly connected with each other. The second insulator comprises a base part, a first gap and a second gap, the first gap and the second gap are arranged between the front end and the rear end of the base part, and the moving terminal and the static terminal respectively comprise a first vertical arm and a second vertical arm which are arranged in the first gap and the second gap, and a first welding part and a second welding part which are formed by horizontally bending the bottoms of the first vertical arm and the second vertical arm. Sol grooves are formed in the first notch and the second notch respectively, and glue is injected into the sol grooves to wrap the peripheries of thefirst vertical arm and the second vertical arm to form glue blocks; and tin climbing during welding can be effectively prevented.

Problems solved by technology

[0003] Due to the development of electronic equipment, radio frequency switches are also required to be further miniaturized. However, in the process of miniaturization of radio frequency switches, the force arm of the elastic parts of the radio frequency switch function will be reduced, and the riveted foot structure in the prior art is difficult to manufacture. And the fixation strength between the components is weak, so that the micro-RF switch fails during the IR furnace and the detection and insertion process, which poses a great challenge to miniaturization, as disclosed in the patent application No. 202010849369.5 submitted by the applicant A separate design using the upper and lower bottom shells to solve the defect that it is difficult to ensure the flatness in the process of riveting with a single metal shell for micro-miniature radio frequency switches

At the same time, the patent No. 202010849369.5 also has the following defects: during the soldering process, the solder feet of the conductive terminals have the problem of climbing tin upwards, causing a short circuit or affecting the elasticity of the moving terminals; The casing is integrally injection molded, and there is insufficient bonding force, and when the second insulator passes through the IR furnace, the second insulator is not tightly combined with the lower casing, so it is easy to warp and deform when heated; the movable terminal is in the process of pressing down , the lack of a limit structure requires sufficient clamping force between the first and second insulators for the movable terminal, resulting in an increase in the internal stress of the plastic and increasing the instability of the product
