[0046] Specifically, the first end of the second extension portion 31 is integrally provided on the second side edge portion 112 , the first end of the second extension portion 31 is provided in the second avoidance groove 116 , and the limiting portion 32 and the elastic portion 33 are integrally provided at the second end of the second extension portion 31 .

[0047] Furthermore, the elastic portion 33 includes a main elastic arm 331 and a pair of contact elastic arms 332 extending from either side of the main elastic arm 331 in a direction away from the second extension portion 31. One end of the main elastic arm 331 is integrally disposed at the second end of the second extension portion 31, and the contact elastic arm 332 is integrally disposed at the other end of the main elastic arm 331. After the static terminal 2 and the movable terminal 3 are bent, the contact elastic arm 332 can elastically contact the contact arm 22 of the static terminal 2.

[0048] Please refer to Figures 2 to 4As shown, an RF switch in one embodiment of the present invention includes an upper housing 4, an insulating member 5, a lower housing 1, a movable terminal 3, and a static terminal 2. The lower housing 1 is docked with the upper housing 4, and a receiving space for the insulating member 5 is formed between the lower housing 1 and the upper housing 4. The insulating member 5 is retained in the receiving space between the upper housing 4 and the lower housing 1. The insulating member 5 includes a first insulator 51 and a second insulator 52 that fit together in the vertical direction to define the movable terminal 3 and the static terminal 2. The movable terminal 3 and the static terminal 2 are clamped between the first insulator 51 and the second insulator 52, and the movable terminal 3 and the static terminal 2 are in elastic contact.

[0049] Among them, the dynamic terminal 3 and the static terminal 2 are formed by bending the dynamic terminal 3 and the static terminal 2 in the RF switch group accessories described in any of the aforementioned embodiments and cutting and separating them from the lower shell 1, and the dynamic terminal 3 and the static terminal 2 are bent and cut to form a welding part for welding.

[0050] In an exemplary embodiment, please refer to Figure 5 and Figure 6 As shown, the upper housing 4 includes a straight upper flat plate portion 41, a docking tube portion 42 located at the center of the upper flat plate portion 41 and protruding upward, and an upper sidewall 43 that bends downward and extends from the side edge of the upper flat plate portion 41. The docking tube portion 42 can be used to mate with the outer shell of the docking connector. A docking hole 421 is provided at the center of the docking tube portion 42, extending vertically through the upper housing 4. The upper sidewall 43 includes two pairs of upper docking portions 431 located on the left and right edges of the upper flat plate portion 41 in the horizontal direction and spaced apart. A spacing space 44 is formed between the two pairs of upper docking portions 431, which can mate with the protruding portion 13 on the lower housing 1.

[0051] For details, please refer to Figure 2 and Figure 3 As shown, when the upper shell 4 and the lower shell 1 are connected, the inner surface of the upper side wall 43 corresponds to the outer surface of the lower side wall 12, and the two can abut and fit together. An overflow groove 45 for accommodating solder is provided between the upper side wall 43 and the lower side wall 12. The overflow groove 45 is used to contain molten liquid solder during welding of the upper side wall 43 and the lower side wall 12, preventing solder bulging. It also increases the contact area between the solder, the upper side wall 43 and the lower side wall 12, and improves the strength of the weld.

[0052] The overflow groove 45 can be provided on the upper side wall 43 or on the lower side wall 12 , as long as the overflow groove 45 can be located between the upper side wall 43 and the lower side wall 12 after the upper shell 4 and the lower shell 1 are docked.

[0053] In an exemplary embodiment, please refer to Figure 7 and Figure 8As shown, the first insulator 51 is integrally injection-molded on the upper shell 4. The first insulator 51 includes a base 511 and a cylindrical portion 512 located at the center of the base 511 and protruding upward. The cylindrical portion 512 is formed in the docking barrel portion 42. A socket 513 is provided at the center of the cylindrical portion 512, which passes through the first insulator 51 from top to bottom. The lower surface of the base 511 is formed with an upper through groove 514 located on one side in the front-to-back direction and extending in the front-to-back direction, and a first pressing portion 515 and a second pressing portion 516 located on the other side, which are arranged in a front-to-back manner and protrude downward. A third pressing portion 517 is formed on both lateral sides of the upper through groove 514, which protrude downward.

[0054] Specifically, the second insulator 52 is integrally injection-molded on the lower housing 1. The second insulator 52 includes a flat base 521, a first notch 522 and a second notch 523 located at the front and rear ends of the base 521, and the welding parts of the dynamic terminal 3 and the static terminal 2 are respectively accommodated in the first notch 522 and the second notch 523. The upper surface of the base 521 is recessed downward to form a lower through groove 524 and a concave space 525. The lower through groove 524 is close to the second notch 523 and is connected to the second notch 523. The concave space 525 is close to the first notch 522 and is connected to the first notch 522. On the upper surface of the base 521, a pair of retaining walls 526 with inclined surfaces are provided at positions on both sides of the first notch 522. The inclined surfaces of the retaining walls 526 are connected to the lower surface of the concave space 525.

[0055] The lower surface of the concave space 525 is lower than the upper surface of the base 521. A first pressing portion 527 and a second pressing portion 528 are disposed within the concave space 525, spaced apart in the front-to-back direction. The lower through-slot 524 includes a deformation space 54 adjacent to the second notch 523, forming a space therebetween, and a channel 55 connecting the deformation space 54 and the concave space 525. Third pressing portions 529 are disposed on either side of the lower through-slot 524, projecting upward from the base 521. Four lower protruding walls 53 are formed on either side of the lateral edge of the base 521, spaced apart and projecting upward in pairs. The second insulator 52 also includes an outer edge 56 extending outward from the front and back sides of the base 521.

[0056] The outer edge portion 56 includes a downwardly projecting outer edge bottom portion 57 and outer edge side portions 58 located on either side of the outer edge portion 56. The lower surfaces of the outer edge bottom portion 57 and the outer edge side portions 58 are lower than the lower surface of the base portion 521. The lateral width between the outer edges of the outer edge side portions 58 on either side of the second insulator 52 is greater than the lateral width of the base portion 521. However, in a preferred embodiment, the lateral width of the outer edge side portions 58 on either side of the second insulator 52 is consistent with the lateral width between the outer edges of the upper housing 4 on either side of the second insulator 52.

[0057] In one embodiment of the present invention, there is also provided an assembly method applicable to the aforementioned radio frequency switch, which comprises the following steps:

[0058] S101 : Injection-molding the first insulator 51 on the upper shell 4 to form an upper mold assembly.

[0059] S102: Injection-molding a second insulator 52 on the lower housing 1 of the radio frequency switch assembly as described above to form a lower module.

[0060] S103 : Bend the movable terminal 3 and the static terminal 2 toward the inner side of the lower flat plate portion 11 so that the movable terminal 3 and the static terminal 2 are in elastic contact with each other.

[0061] S104: Snap the upper mold assembly onto the lower mold assembly, and weld the upper shell 4 and the lower shell 1.

[0062] S105 : cutting the movable terminal 3 and the static terminal 2 to separate the movable terminal 3 and the static terminal 2 from the lower housing 1 .

[0063] The present invention will be further described below in conjunction with a specific assembly process.

[0064] First, the aforementioned radio frequency switch assembly components and the upper housing 4 are manufactured by a metal stamping process.

[0065] Then, the first insulator 51 is integrally injection molded with the upper housing 4 to form an upper mold assembly. The upper surface of the base 511 of the first insulator 51 is in contact with the upper flat plate 41 of the upper housing 4, and the cylindrical portion 512 is fixed in the docking hole 421 of the docking barrel portion 42.

[0066] The second insulator 52 and the lower shell 1 are integrally injection molded to form a lower mold assembly. Figure 9 As shown. The lower surface of the base 521 of the second insulator 52 is in contact with the upper surface of the lower flat plate portion 11. The first relief groove 115 corresponds to the first notch 522, and the second relief groove 116 corresponds to the second notch 523. The outer surfaces of the two lateral sides of the base 521 are in contact with the inner surface of the lower side wall 12, and the outer surfaces of the four lower protruding walls 53 are in contact with the inner surface of the lower side wall 12.

[0067] The outer edge portion 56 is retained outside the front and rear edges of the lower flat plate portion 11. The lower edges of the two lower side edge walls arranged front and rear of the lower side wall 12 are recessed to form retaining recesses. The outer edge side portions 58 of the outer edge portion 56 are retained in the retaining recesses, thereby further securing the front and rear outer edges of the second insulator 52 to the lower housing 1.

[0068] It should be noted that in some embodiments, to facilitate the integral injection molding process of the second insulator 52 and the lower housing 1, a glue injection hole 14 may be provided through the lower flat plate portion 11 of the lower housing 1. The lower surface of the base 521 of the second insulator 52 protrudes downward to form a glue injection portion 59 corresponding to the glue injection hole 14. The glue injection portion 59 is retained within the glue injection hole 14, and the lower surface of the glue injection portion 59 does not extend downward beyond the lower surface of the lower flat plate portion 11. The glue injection hole 14 is the preferred injection location for the injection molding machine.

[0069] Then, the second extension portion 31 of the movable terminal 3 is bent toward the inner side of the lower flat portion 11 so that the second extension portion 31 is close to the extension portion of the second side edge portion 112. After bending, a welding portion accommodated in the second notch 523 can be formed, and the elastic portion 33 can extend backward through the deformation space 54 and the channel 55 to the recessed space 525.

[0070] The first extension portion 21 of the static terminal 2 is then bent toward the inner side of the lower flat portion 11 so that the first extension portion 21 is close to the extension portion of the first side edge portion 111. After bending, a welding portion is formed to be accommodated in the first notch 522, and the pair of contact spring arms 332 of the movable terminal 3 elastically contacts the pair of contact arms 22 of the static terminal 2 from bottom to top. Figure 10 shown.

[0071] The upper and lower mold assemblies are assembled vertically, interlocking the upper and lower slots 514 and 524, the insertion holes 513, and the concave space 525. The first and second upper pressing portions 515 and 516 correspond vertically with the first and second lower pressing portions 527 and 528, respectively, and clamp the extended portion of the first extension 21 proximal to the contact arm 22. The pair of contact arms 22 are suspended above the concave space 525. The third upper pressing portion 517 and third lower pressing portion 529 correspond vertically with each other, clamping the stopper 32 to secure the movable terminal 3.

[0072] The elastic portion 33 elastically contacts the contact arm 22 upward. The elastic portion 33 is subjected to upward and downward pressure from the static terminal 2 and the lower mold assembly, causing it to elastically deform downward, forming a non-upward arched shape. During the assembly and fixation of the upper and lower mold assemblies, the elastic portion 33 is compressed from its initial shape to its current non-arched shape. The free end of the contact spring arm 332 abuts against the inclined surface of the retaining wall 526, creating a strong elastic contact force between the dynamic terminal 3 and the static terminal 2.

[0073] The outer surface of the lower sidewall 12 of the lower shell 1 is aligned with the inner surface of the upper sidewall 43 of the upper shell 4. The lower surface of the upper sidewall 43 is higher than the lower surface of the lower flat plate 11. A welding groove is formed between the lower edge of the upper sidewall and the outer surface of the lower sidewall, and an overflow groove 45 is connected to the welding groove. A welding process is then performed at the welding groove. The molten liquid solder during the welding process flows into the overflow groove 45, thereby stably holding the upper shell 4 and the lower shell 1 together.

[0074] Finally, through the laser cutting process, the connection between the first extension portion 21 and the first side edge portion 111, and the connection between the second extension portion 31 and the second side edge portion 112 are cut to separate the static terminal 2 and the dynamic terminal 3 from the lower shell 1, thereby avoiding electrical connection between the static terminal 2 and the dynamic terminal 3 and the lower shell 1, thereby completing the assembly of the RF switch.

[0075] The foregoing descriptions of specific exemplary embodiments of the present invention are for purposes of illustration and description. These descriptions are not intended to limit the invention to the precise forms disclosed, and it is apparent that many variations and modifications are possible in light of the foregoing teachings. The exemplary embodiments have been selected and described for the purpose of explaining the specific principles of the invention and their practical application, thereby enabling those skilled in the art to realize and utilize a variety of exemplary embodiments of the invention and various options and modifications.
