The upper shell 20 and the lower shell 30 can be made by metal stamping process, or can also be made by metal powder metallurgy process.

[0034] Please refer to Figures 4 to 7 As shown, the insulating body 105 includes a first insulator 40 and a second insulator 50 disposed below the first insulator 40. The first insulator 40 is integrally formed with the upper shell 20. The first insulator 40 includes an upper base 41 and a cylindrical portion 42 located at the center of the upper base 41 and protruding upward. The cylindrical portion 42 is fixed in the docking cylindrical portion 23 of the upper shell 20. A plug hole 43 that passes through the first insulator 40 from top to bottom is provided at the center of the cylindrical portion 42, and the plug hole 43 is used for inserting a docking probe (not shown).

[0035] The second insulator 50 is integrally formed with the lower shell 30. The second insulator 50 includes a lower base 51 arranged flat, a first notch 52 located on one side of the lower base 51 in the front-to-back direction, a second notch 53 located on the other side, and two fixing walls 54 located on both sides of the lower base 51 in the transverse direction. The upper surface of the lower base 51 is recessed downward to form a receiving space 55 extending in the front-to-back direction so that the conductive terminal 106 can dock therein. The lower end of the lower base 51 is filled with the through hole 35 and the recessed portion 34 of the lower shell 30, and the lower end surface of the lower base 51 is flush with the other areas of the bottom plate 31 except the recessed portion 34, so as to achieve the purpose of stably holding the second insulator 50 and the lower shell 30. Each of the fixing walls 54 is matched with the lower end wall 36 of the lower shell 30, and blocks the second spacing space 37 to prevent flux or dust from entering the receiving space 55 and affecting the contact stability of the terminal. The first notch 52 corresponds to the first clearance groove 32 , and the second notch 53 corresponds to the second clearance groove 33 .

[0036] Please refer to Figures 4 to 7 As shown, the conductive terminal 106 includes a static terminal 70 and a movable terminal 60 elastically contacting the static terminal 70. The movable terminal 60 is located at the front end of the RF switch 100 in the front-to-back direction, and the static terminal 70 is located at the rear end of the RF switch 100 in the front-to-back direction, and the movable terminal 60 elastically contacts the lower end of the static terminal 70 upward.

[0037] The movable terminal 60 includes a first holding portion 61 extending transversely, a first welding portion 62 bent downward from the center of the front edge of the first holding portion 61 to form a straight setting, and a first elastic contact portion 63 extending backward along the front-to-back direction from the center of the rear edge of the first holding portion 61. The static terminal 70 includes a second holding portion 71 extending forward along the front-to-back direction, a second welding portion 72 bent downward from the rear end of the second holding portion 71 to form a straight setting, and a second contact portion 73 bent from the front end of the second holding portion 71.

[0038] The first insulator 40 and the second insulator 50 fix the first holding portion 61 and the second holding portion 71 of the movable terminal 60 and the static terminal 70 in the up-down direction. The first welding portion 62 of the movable terminal 60 is received in the first notch 52, and the second welding portion 72 of the static terminal 70 is received in the second notch 53. The first contact portion 63 of the movable terminal 60 and the second contact portion 73 of the static terminal 70 are suspended in the receiving space 55, and the first contact portion 63 elastically contacts the lower end of the second contact portion 73 upward. When the movable terminal 60 is in elastic contact with the static terminal 70, the first contact portion 63 of the movable terminal 60 is in a state of nearly planar extension; when the movable terminal 60 is pressed downward by a probe (not shown), the first contact portion 63 is elastically deformed to be concave downward until the first contact portion 63 is downwardly separated from the lower end of the second contact portion 73 of the static terminal 70. During this process, the end of the first contact portion 63 is tilted and moves toward the first welding portion 62 of the movable terminal 60; when the probe (not shown) is removed, the first contact portion 63 elastically recovers upward to a state of elastic contact with the lower end of the second contact portion 73.

[0039] In order to make the first contact portion 63 of the movable terminal 60 have good elasticity and recoverability, and ensure the stable contact between the movable terminal 60 and the static terminal 70, in the first embodiment provided by the utility model, the first contact portion 63 of the movable terminal 60 includes a first elastic arm 64 with elasticity extending from the center position of the rear end edge of the first holding portion 61 along the front-to-back direction, and a pair of first support arms 65 extending backward from the ends of the first elastic arm 64 on both sides. The second contact portion 73 of the static terminal 70 includes a pair of contact arms 74 bent upward and extended from both sides of the front end of the second holding portion 71. The pair of first support arms 65 elastically contact the lower ends of the corresponding pair of contact arms 74 upward. The setting of the pair of first support arms 65 can make the first contact portion 63 have good pressure resistance, and ensure the stable contact between the movable terminal 60 and the static terminal 70.

[0040] Please refer to Figure 8As shown, the utility model also provides a second embodiment, which is different from the first embodiment in that the first contact portion 63' of the movable terminal 60' includes a second elastic arm 81 with elasticity extending from the center position of the rear end edge of the first retaining portion 61' along the front-to-back direction, a pair of second support arms 82 extending backward from the lateral sides of the end of the second elastic arm 81, and a pair of third support arms 83 extending from the middle section of the second elastic arm 81 and respectively connected to the ends of the second support arms 82, and the pair of second support arms 82 elastically contact the lower ends of the corresponding pair of contact arms 74 of the static terminal 70 upwards. Compared with the first embodiment, this embodiment can also achieve the purpose of making the first contact portion 63' have good pressure resistance by increasing the number of support arms.

[0041] Please refer to Fig. 9 As shown, the utility model also provides a third embodiment, which is different from the first embodiment in that the first contact portion 63" of the movable terminal 60" includes a third elastic arm 84 with elasticity extending from the center position of the rear end edge of the first retaining portion 61" along the front-to-back direction, and a pair of fourth support arms 85 extending backward from the lateral sides of the end of the third elastic arm 84. Each of the fourth support arms 85 includes a first section 86 extending backward from the end of the third elastic arm 84 and a second section 87 extending forward and backward from the end of the first section 86 and supported on the surface of the second insulator 50. The first section 86 elastically contacts the lower ends of the corresponding pair of contact arms 74 of the static terminal 70 upward. Compared with the first embodiment, this embodiment can also achieve the purpose of making the first contact portion 63" have good pressure resistance by increasing the force arm length of the support arm.

[0042] The upper housing 20 and the first insulator 40 are integrally formed into an upper module, and the lower housing 30 and the second insulator 50 are integrally formed into a lower module. After the upper module, the static terminal 70, the dynamic terminal 60 and the lower module are assembled in the up-down direction, the upper housing 20 and the lower housing 30 are fixed by laser welding to finally form the RF switch 100.

[0043] Please refer to Figure 3As shown, the inner surface of the upper end wall 24 of the upper shell 20 corresponds to the outer surface of the lower end wall 36 of the lower shell 30, and a welding seam 103 for welding is formed at the lower end. When viewed in the up and down direction, the front end surfaces of the upper end wall 24 and the lower end wall 36 of the upper shell 20 and the lower shell 30 near the front end are flush, and the rear end surfaces of the upper end wall 24 and the lower end wall 36 near the rear end of the upper shell 20 and the lower shell 30 are flush, so that the length of the welding seam 103 formed between the upper end wall 24 and the lower end wall 36 can be extended, so that when selecting the welding point on the welding seam 103, it can be far away from the wing 38, avoiding damage to the wing 38 at the welding point 104 during laser welding, ensuring the stability of the RF switch 100 after being welded to the circuit board, and also conducive to product miniaturization.

[0044] Compared with the prior art, the radio frequency switch 100 of the utility model has the following advantages: in the front-to-back direction, since the front end surfaces and rear end surfaces of the upper end walls 24 and the lower end walls 36 of each group of the upper shell 20 and the lower shell 30 are arranged flush, a space away from the wing 38 serving as a welding pad is provided for laser welding, thereby avoiding damage to the wing 38 by laser welding and ensuring the stability of the final product welded to the circuit board; and due to the arrangement of the upper and lower shells and the movable terminal 60 having a longer elastic support arm, the radio frequency switch 100 of the utility model has a greater overall strength during the IR furnace and detection plug-in process, and the conductive terminal 106 and the insulating body 105 are effectively supported, thereby avoiding failure, which is beneficial to miniaturized design.

[0045] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, 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.

[0046] The above embodiments only express the preferred implementation of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
