Simultaneously, the straight second connecting portion is supported upwards by a protrusion. When the RF switch with this moving terminal is in the SMT soldering process, the plastic component may soften due to heat. The second connecting portion increases the support area between the moving terminal and the lower plastic base, effectively preventing the release of elastic force in the elastic contact between the moving terminal and the stationary terminal, ensuring stable contact between the moving terminal and the stationary terminal, and improving the overall service life. Furthermore, by reducing the contact area, the interference of external environmental factors on the contact stability of the terminals is effectively reduced, resulting in more reliable electrical connection performance in practical applications. This achieves the technical effect of improving contact stability and enhancing reliability. Attached Figure Description

[0034] This utility model provides a moving terminal, please refer to... Figures 1 to 4 As shown, Figure 1 This is a schematic diagram of the structure of a moving terminal provided in an embodiment of this utility model. Figure 2 This is a schematic diagram of the structure of the contact end in a moving terminal according to an embodiment of the present invention. Figure 3 This is a schematic diagram of the structure of the first side connecting part and the second side connecting part in a moving terminal according to an embodiment of the present invention. Figure 4 This is a schematic diagram of the contact end structure of a moving terminal according to an embodiment of the present invention. The moving terminal provided in this embodiment includes a first welding foot 1, a contact portion 2, and a fixing portion 3. The fixing portion 3 is connected to both the first welding foot 1 and the contact portion 2. The first welding foot 1, the contact portion 2, and the fixing portion 3 can be integrally formed. The fixing portion 3 is formed by bending and extending from one end of the first welding foot 1. The contact portion 2 includes a first connecting portion 21, a contact end 22, and a second connecting portion 23. The first connecting portion 21 is formed by bending and extending from one end of the fixing portion 3. The contact end 22 is formed by bending from one end of the first connecting portion 21. The second connecting portion 23 is formed by horizontally extending from one end of the fixing portion 3. For example, if the second connecting portion 23 extends along the X-axis direction, the second connecting portion 23 will be straight. The contact end 22 will be forked along the direction away from the fixing portion 3. Figure 2 As shown, the forked shape of the contact end 22 means that the contact end 22 forms two contact ends arranged at intervals along the direction away from the fixing part 3, and each contact end is tapered along the direction away from the fixing part 3.

[0035] Among them, such as Figure 2 As shown, the first direction is perpendicular to the fixing part 3, and the second direction is parallel to the fixing part 3. Figure 2 The horizontal direction is parallel to the second direction and perpendicular to the first direction. For example, the second direction is parallel to the extension direction of the second connecting portion 23, the first direction can be the Y-axis direction, the second direction can be the X-axis direction, and the Y-axis direction and the X-axis direction are perpendicular to each other. The contact end 22 can be formed by bending from the first connecting portion 21 in any direction away from the first connecting portion 21. The cross-section of the contact end 22 at the contact point is tapered along the direction away from the first connecting portion 21, such as forming a blade-shaped or wedge-shaped structure. The second connecting portion 23 is connected to the fixing portion 3, and the second connecting portion 23 extends horizontally along the X-axis direction, that is, the main body of the second connecting portion 23 is a flat plate structure without bending.

[0036] The tapered surface of the contact end 22 can be polished to reduce the surface roughness of the contact end 22 and form a micro-smooth slope, so that only the top small area of ​​the tapered surface contacts the stationary terminal 9 below in the working state.

[0037] In this embodiment, the contact end 22 is bent from the first connecting portion 21 toward the Y-axis direction. The second connecting portion 23 and the first connecting portion 21 are respectively connected to the fixing portion 3, and the second connecting portion 23 extends along the X-axis direction. The second connecting portion 23 is straight, and the contact end 22 is forked in the direction away from the first connecting portion 21. This forked contact end 22, which is used to contact the stationary terminal 9, helps to reduce the contact area between the contact end 22 and the stationary terminal 9. From a microscopic perspective, this reduces the influence of external factors such as dust and effectively improves the stability of product contact. At the same time, the straight second connecting portion is supported upward by the protrusion. When the RF switch with this moving terminal is in the SMT soldering process, the plastic component may soften due to heat. The second connecting portion can increase the support area between the moving terminal and the lower plastic base, effectively preventing the elastic force of the elastic contact between the moving terminal and the stationary terminal from being released, ensuring stable contact between the moving terminal and the stationary terminal, and improving the overall service life. Furthermore, by reducing the contact area, the interference of external environmental factors on the contact stability of the terminals is effectively reduced, resulting in more reliable electrical connection performance in practical applications. This achieves the technical effect of improving contact stability and enhancing reliability.

[0038] In some embodiments, there are multiple contact ends 22. The connection between two adjacent contact ends in each contact end 22 is arc-shaped, and the multiple contact ends 22 have the same height in the first direction, that is, the multiple contact ends 22 have the same height along the Y-axis direction, and the contact ends in each contact end 22 have the same height along the Y-axis direction. For example, two contact ends 22 are arranged along the first connecting portion 21, and the two contact ends in each contact end 22 are transitioned by an arc with a certain radius of curvature, and the height of all contact ends can be kept consistent. The arrangement of multiple contacts disperses the total contact area into multiple regions, which is beneficial to the contact effectiveness compared to a single contact. At the same time, the uniformity of height ensures that each contact is subjected to balanced force, which helps to reduce external environmental interference.

[0039] In one embodiment, the second connecting portion 23 includes a first side surface 231, a second side surface 232, a third side surface 233, and a fourth side surface 234. The second side surface 232 is opposite to the first side surface 231. The third side surface 233 connects the first side surface 231 and the second side surface 232. The fourth side surface 234 connects the first side surface 231 and the second side surface 232, and the fourth side surface 234 is opposite to the third side surface 233. The first side surface 231 and the second side surface 232 are parallel to each other and are parallel to the X-axis direction. The third side surface 233 and the fourth side surface 234 are parallel to the fixing portion 3, that is, the third side surface 233 and the fourth side surface 234 are parallel to the Y-axis direction. The second connecting portion 23 has a rectangular cross-section and is formed by the first side surface 231 and the second side surface 232 parallel to the X-axis direction, and the third side surface 233 and the fourth side surface 234 perpendicular to the Y-axis direction, thus constructing a plate-like structure of equal thickness.

[0040] In some embodiments, the second connecting portion 23 includes a first side connecting portion 235 and a second side connecting portion 236 respectively connected to the end of the fixing portion 3 away from the first welding foot 1. The first connecting portion 21 is located between the first side connecting portion 235 and the second side connecting portion 236. The first side connecting portion 235 and the second side connecting portion 236 form the second connecting portion 23. The first side connecting portion 235 and the second side connecting portion 236 are symmetrically distributed on both sides of the first connecting portion 21 in the X-axis direction, that is, the first side connecting portion 235 and the second side connecting portion 236 provide support for the first connecting portion 21 from both sides.

[0041] In some embodiments, the fixing part 3 is provided with a first positioning groove 41, a second positioning groove 42 and a through hole 43. For example, the first positioning groove 41 is located on the same side of the fixing part 3 as the first side connecting part 235, the second positioning groove 42 is located on the same side of the fixing part 3 as the second side connecting part 236, and the through hole 43 is located between the first positioning groove 41 and the second positioning groove 42. The first positioning groove 41 and the second positioning groove 42 can be symmetrically distributed on both sides of the through hole 43. The first positioning groove 41 and the second positioning groove 42 are respectively used for the insertion of the corresponding positioning post 822 on the base 82 in the upper plastic part 8. The through hole 43 is used to avoid the glue injection point (not shown) of the upper plastic part 8.

[0042] To provide a detailed description of the radio frequency switch provided by this utility model, the above embodiments have described a moving terminal in detail. Based on the same inventive concept, this application also provides a radio frequency switch.

[0043] Please see Figures 5 to 9 As shown, Figure 5 This is a schematic diagram of the structure of a radio frequency switch provided in an embodiment of the present invention. Figure 6This is a schematic diagram of the upper plastic part of a radio frequency switch provided in an embodiment of the present invention. Figure 7 This is a schematic diagram of the structure of a first limiting block, a second limiting block, and a protrusion in a radio frequency switch according to an embodiment of the present invention. Figure 8 This is a schematic diagram of the structure of a receiving groove in a radio frequency switch provided by an embodiment of the present invention. Figure 9 This is a schematic diagram of the structure of a boss in a radio frequency switch provided by an embodiment of the present invention. The present invention provides a radio frequency switch including a metal housing 6, an upper plastic portion 8, a stationary terminal 9, a moving terminal, and a lower plastic base 5, which are sequentially fixed inside the metal housing 6 from top to bottom. The lower plastic base 5 has a protrusion 51 and a receiving groove 52. Furthermore, the metal housing 6, the upper plastic portion 8, and the stationary terminal 9 are integrally formed, and the moving terminal is sandwiched between the upper plastic portion 8 and the lower plastic base 5 and is in contact with the stationary terminal 9.

[0044] The metal housing 6 has a space inside to accommodate the upper plastic part 8, the stationary terminal 9, the moving terminal and the lower plastic base 5. The accommodating groove 52 has a space inside to accommodate the first connecting part 21. The protrusion 51 and the second connecting part 23 abut against each other. The stationary terminal 9 abuts against the contact end 22. The projection of the second connecting part 23 along the Y-axis direction onto the protrusion 51 is at least partially located on the protrusion 51. The protrusion 51 can support the second connecting part 23 upward along the first direction. The second connecting part 23 is located between the protrusion 51 and the upper plastic part 8.

[0045] When the first connecting part 21 is pressed down with a probe (not shown), the first connecting part 21 will bend downward, causing the contact end 22 connected to the first connecting part 21 to separate from the stationary end 9. At this time, the fixing part 3 is clamped along the first direction by the upper plastic part 8 and the boss 57 located on the lower plastic base 5, so as to constrain the spatial position of the fixing part 3 and the second connecting part 23 connected to the fixing part 3, so that the second connecting part 23 remains in a straight state.

[0046] In one embodiment, the metal housing 6 includes a cylindrical portion 61, a clamping portion 63, and a through groove 62 disposed on the cylindrical portion 61. The clamping portion 63 is connected to the cylindrical portion 61 and is used to clamp the lower plastic base 5. The clamping portion 63, the lower plastic base 5, and the cylindrical portion 61 enclose a space for holding the upper plastic portion 8, the stationary terminal 9, and the aforementioned moving terminal. When viewed along a first direction, the projection of the through groove 62 at least partially overlaps with the projection of the first connecting portion 21, that is, the projection of the through groove 62 along the Y-axis direction onto the first connecting portion 21 is at least partially located on the first connecting portion 21, allowing the probe to be inserted from the through groove 62 until it contacts the first connecting portion 21. The upper plastic part 8 includes a docking part 81 and a base 82. The docking part 81 is embedded inside the through groove 62 and a guide groove 811 is provided on the docking part 81. The base 82 is connected to the docking part 81 and a snap-fit ​​groove 821 is provided on the base 82. The second connecting part 23 is located between the protrusion and the base 82, so that the second connecting part 23 can be constrained at the position between the protrusion and the base 82.

[0047] In one embodiment, the aforementioned stationary terminal 9 includes a second welding foot 91 and a third connecting portion 92. The third connecting portion 92 bends from the second welding foot 91 toward the Y-axis direction and then extends along the X-axis direction. The third connecting portion 92 passes through the aforementioned snap-fit ​​groove 821. The third connecting portion 92 protrudes downward along the first direction from the bottom surface of the base 82. When viewed along the first direction, the projections of the third connecting portion 92 and the contact end 22 at least partially overlap. The contact end 22 is suspended in the receiving groove 52, and the contact end 22 abuts upward against the lower surface of the third connecting portion 92, so that the forked contact end 22 can always form point contact with the third connecting portion 92. That is, after the pressure of pressing the first connecting portion 21 is removed, the first connecting portion 21 restores its deformation and drives the contact end 22 to abut upward against the lower surface of the third connecting portion 92 again.

[0048] In one embodiment, the lower plastic base 5 is provided with a first clearance groove 53 and a second clearance groove 54. The first clearance groove 53 and the second clearance groove 54 are distributed opposite to each other. The first clearance groove 53 is directly opposite the first welding pin 1, and the second clearance groove 54 is directly opposite the second welding pin 91. The projection of the first welding pin 1 along the X-axis in the first clearance groove 53 is at least partially located within the first clearance groove 53, and the projection of the second welding pin 91 along the X-axis in the second clearance groove 54 is at least partially located within the second clearance groove 54. The projection of the first welding pin 1 along the X-axis can fall into the first clearance groove 53, and the projection of the second welding pin 91 can fall into the second clearance groove 54. The first clearance groove 53 and the second clearance groove 54 can accommodate a portion of the flux during the welding process, preventing the flux from entering between the moving terminal and the stationary terminal and contaminating their surfaces, thus ensuring the stability of the contact end 22 and the third connection part 92 during long-term use.

[0049] In one embodiment, the contact portion 2 further includes a first side arm segment 24 and a second side arm segment 25. The first side arm segment 24 and the second side arm segment 25 are respectively connected to the first welding foot 1, which is located between the first side arm segment 24 and the second side arm segment 25. A first limiting block 55 and a second limiting block 56 are provided on the lower plastic base 5. The first limiting block 55 is in contact with the first side arm segment 24, and the second limiting block 56 is in contact with the second side arm segment 25. Through the first limiting block 55 and the second limiting block 56 on the lower plastic base 5, surface contact can be formed with the first side arm segment 24 and the second side arm segment 25, respectively. The first limiting block 55 and the second limiting block 56 can provide lateral stiffness to prevent the straight second connecting portion 23 from plastically bending during repeated elastic deformation, which is beneficial to extending its service life.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
