[0032] The utility model provides a movable terminal according to the first embodiment. Figures 1 to 2 As shown, Figure 1 This is a structural diagram of a movable terminal provided by an embodiment of the utility model. Figure 2Schematic diagram of the structure of the upper connecting arm 22 and the lower connecting arm 24 in a movable terminal provided by an embodiment of the present invention. The movable terminal provided by an embodiment of the present invention includes a first welding portion 1 and a first connecting component 2, the first connecting component 2 includes a first connecting arm 21, an upper connecting arm 22, a second connecting arm 23 and a lower connecting arm 24, the first connecting arm 21 is bent from the first welding portion 1 in the Y-axis direction and extends along the X-axis direction, the upper connecting arm 22 is bent from the first connecting arm 21 in the Y-axis direction, the second connecting arm 23 is connected to the first connecting arm 21 and extends along the X-axis direction, and the lower connecting arm 24 is bent from the second connecting arm 23 in the opposite direction to the bending direction of the upper connecting arm 22 Bending toward the left, the second connecting arm 23 includes a top side 231, a bottom side 232, a left side 233 and a right side 234. The bottom side 232 is opposite to the top side 231. The left side 233 is respectively connected to the top side 231 and the bottom side 232. The right side 234 is respectively connected to the top side 231 and the bottom side 232. The right side 234 is opposite to the left side 233. The top side 231 and the bottom side 232 are parallel to each other, and the top side 231 and the bottom side 232 are respectively parallel to the X-axis direction, and the left side 233 and the right side 234 are respectively parallel to the Y-axis direction.

[0033] Among them, the first connecting part 2 starts from the first welding part 1, and is first bent in the Y-axis direction to form a first connecting arm 21 to achieve the initial positioning of the moving terminal in space. Then the first connecting arm 21 extends along the X-axis direction to provide sufficient length and flexibility for subsequent connections. The upper connecting arm 22 is bent again from the end of the first connecting arm 21 in the Y-axis direction to form a certain spatial height, which helps the moving terminal to maintain an appropriate gap with the static terminal 7 during the assembly process to avoid unnecessary contact or interference. The second connecting arm 23 not only extends along the X-axis direction to maintain continuity with the first connecting arm 21, but also forms parallel top side surfaces 231 and bottom side surfaces 232 on the upper and lower sides of the second connecting arm 23, which not only enhances the structural strength of the second connecting arm 23, but also provides a stable electrical transmission path. At the same time, the left side 233 and the right side 234 are straight-face structures, which also makes the overall structure of the second connecting arm 23 present a straight-arm structure. The movable terminal will retain more elasticity, and the lower connecting arm 24 is bent from the end of the second connecting arm 23 in the direction opposite to the bending direction of the upper connecting arm 22, which helps to fix and position the movable terminal during the assembly process. The lower connecting arm 24 can abut against the boss 52 in the base 5 described below to achieve a stable installation of the movable terminal. In addition, in a movable terminal provided by an embodiment of the present invention and a radio frequency switch described below, the direction of the X axis and the direction of the Y axis are as follows: Figure 2 shown.

[0034] In this embodiment, the first connecting arm 21 in the first connecting component 2 is bent from the first welding portion 1 toward the Y-axis and extended along the X-axis, the upper connecting arm 22 is bent from the first connecting arm 21 toward the Y-axis, the second connecting arm 23 is connected to the first connecting arm 21 and extends along the X-axis, and the lower connecting arm 24 is bent from the second connecting arm 23 in the direction opposite to the bending direction of the upper connecting arm 22. The left side 233 of the second connecting arm 23 is respectively connected to the top side 231 and the bottom side 232, and the right side 234 opposite to the left side 233 is respectively connected to the top side 231 and the bottom side 232, the top side 231 and the bottom side 232 are parallel to each other, and the top side 231 and the bottom side 232 are respectively parallel to the direction of the X-axis, and the left side 233 and the right side 234 are respectively parallel to the Y-axis. In this way, the second connecting arm 23 has an unbent straight arm structure, and the first welding portion 1 serves as a fixed end for a stable connection between the movable terminal and components such as a circuit board. The unbent straight arm structure eliminates the effect of bending stress on the elasticity of the lever arm. The unbent lever arm allows the movable terminal to retain more elasticity and is less likely to yield, which is beneficial for improving the stability and service life of the movable terminal. At the same time, because the second connecting arm 23 has an unbent straight arm structure, the production of the stamping die is easier, the dimensional accuracy of the movable terminal is higher, and the subsequent assembly process is also facilitated, which is beneficial for improving assembly efficiency. This achieves the technical effect of enhancing the stability of the movable terminal and improving accuracy and assembly efficiency.

[0035] As an embodiment, the number of the second connecting arms 23 is two, and the two second connecting arms 23 are respectively located on both sides of the first connecting arm 21. The two second connecting arms 23 are respectively located on both sides of the first connecting arm 21, and both maintain an unbent straight arm structure. That is, two second connecting arms 23 are respectively connected to both sides of the first connecting arm 21, and both second connecting arms 23 extend along the X-axis direction and maintain a straight arm state. The two second connecting arms 23 are respectively located on both sides of the first connecting arm 21, which not only enhances the overall structural strength of the movable terminal, but also enables the movable terminal to distribute stress more evenly when subjected to force, thereby improving the stability and service life of the movable terminal. At the same time, since the second connecting arm 23 maintains an unbent straight arm structure, it will also eliminate the influence of bending stress on the elasticity of the force arm, so that the movable terminal can retain more elasticity and is not easily surrendered.

[0036] In some embodiments, a curved surface 25 is provided at the junction of the first connecting arm 21 and the right side 234. This curved surface 25 effectively reduces stress concentration at this junction, thereby improving the fatigue resistance of the movable terminal. The curved surface 25 also increases the flexibility of the structure, allowing the movable terminal to better adapt to deformation when subjected to stress, thereby improving its stability and service life.

[0037] In some embodiments, the lower end connecting arm 24 is connected with the second connecting arm 23, and the lower end connecting arm 24 at least comprises a bending section 241 and a straight section 242, the straight section 242 is connected with the bending section 241, and the straight section 242 is parallel to the bottom side surface 232. The bending section 241 of the lower end connecting arm 24 is combined with the straight section 242, so as to not only make the movable terminal abut against the boss 52, but also ensure the compactness and stability of the whole structure, and the straight section 242 is parallel to the bottom side surface 232, so that the lower end connecting arm 24 can better transmit and disperse stress when being stressed.

[0038] In some embodiments, the first inclined surface 26 is arranged at the connection between the bottom side surface 232 and the lower end connecting arm 24, the lower end connecting arm 24 further comprises an inclined section 243, the inclined section 243 is connected with the straight section 242, the second inclined surface 2431 is arranged on the inclined section 243, the second inclined surface 2431 is inclined in a direction away from the bottom side surface 232, and the inclination direction of the first inclined surface is opposite to that of the second inclined surface 2431. The arrangement of the first inclined surface 26 at the connection between the bottom side surface 232 and the lower end connecting arm 24 and the second inclined surface 2431 on the inclined section 243, and the opposite inclination directions of the first inclined surface 26 and the second inclined surface 2431 can effectively reduce stress concentration and deformation at the position, and improve the fatigue resistance of the movable terminal. Meanwhile, when the second connecting arm 23 is deformed under pressure, the first inclined surface 26 and the second inclined surface 2431 have a space for moving relative to each other.
