[0033] ​The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of the present application.

[0034] The present application also provides a protective shell. As shown in Figure 1 The protective shell 10 includes a plate-shaped support portion 110, a plate-shaped limiting portion 120, a first pair of clamping arms 131 and a second pair of clamping arms 132. As shown in Figure 4 The protective shell 10 is used to fix the radio frequency coaxial connector 20. In use, the protective shell 10 is fixed in an electronic device, for example, is welded in the electronic device, and then the radio frequency coaxial connector 20 is inserted into the protective shell 10 to fix the radio frequency coaxial connector 20.

[0035] As shown in Figure 4 The plate-shaped support portion 110 of the protective shell 10 is used to support the back of the radio frequency coaxial connector 20. As shown in Figure 1 The plate-shaped limiting portion 120 of the protective shell 10 is arranged at a first end A of the plate-shaped support portion 110 along the length direction. The first pair of clamping arms 131 and the second pair of clamping arms 132 are arranged in sequence along the length direction of the plate-shaped support portion 110. In the present application, the length direction, the width direction and the thickness direction are defined as the Y direction, the X direction and the Z direction as shown in Figure 1 The first pair of clamping arms 131 and the second pair of clamping arms 132 are arranged in sequence along the length direction (Y direction), so that the first pair of clamping arms 131 and the second pair of clamping arms 132 can clamp different positions of the radio frequency coaxial connector 20 along the length direction (Y direction), thereby achieving better fixing effect.

[0036] As shown in Figure 1 Each pair of clamping arms (the first pair of clamping arms 131 and the second pair of clamping arms 132) includes two clamping arms arranged oppositely. As shown in Figure 1 The first pair of clamping arms 131 includes two oppositely arranged clamping arms (131a, 131b), and the second pair of clamping arms 132 also includes two oppositely arranged clamping arms (132a, 132b), thereby facilitating clamping of the radio frequency coaxial connector 20. As shown in Figure 1 The two clamping arms of each pair of clamping arms (the first pair of clamping arms 131 and the second pair of clamping arms 132) are arranged on both sides of the plate-shaped support portion 110, specifically on both sides of the plate-shaped support portion 110 along the width direction (X direction). In use, reference Figure 3 and Figure 4As shown, the radio frequency coaxial connector 20 is inserted between the first pair of clamping arms 131 and the second pair of clamping arms 132 along the length direction of the plate-shaped support part 110 of the protective shell 10, and abuts against the plate-shaped limiting part 120. After assembly, as shown in Figure 4 The plate-shaped limiting part 120 limits the radio frequency coaxial connector 20 in the length direction (Y direction), i.e. the front and back direction; the first pair of clamping arms and the second pair of clamping arms limit the radio frequency coaxial connector 20 in the width direction (X direction), i.e. the left and right direction; and the plate-shaped support part 110 supports the back of the radio frequency connector and limits it in the up and down direction.

[0037] Further, the radio frequency coaxial connector 20 can also be clamped by the gap between the first pair of clamping arms and the plate-shaped support part 110, thereby more stably limiting the radio frequency coaxial connector 20 in the up and down direction. Specifically, as shown in Figure 2 As shown, the gap d between the clamping arms of the first pair of clamping arms 131 and the plate-shaped support part 110 is in the thickness direction (Z direction) of the plate-shaped support part 110, and in combination with Figure 4 As shown, the gap d is used to catch the edge of the radio frequency coaxial connector 20 to fix it, thereby limiting the radio frequency coaxial connector 20 in the thickness direction (Z direction). As shown in Figure 4 As shown, the radio frequency coaxial connector 20 has a convex edge 2111 extending outward on both sides, which can be caught in the gap d when the radio frequency coaxial connector 20 is inserted into the protective shell 10, thereby making the radio frequency coaxial connector 20 be clamped in the thickness direction (Z direction) and unable to move up and down, and the fixing effect is better.

[0038] The above protective shell 10 can fix and limit the radio frequency coaxial connector 20, avoid the radio frequency coaxial connector 20 from shaking during use, make the radio frequency coaxial connector 20 have good holding force, thereby ensuring the reliability of the connection between the radio frequency coaxial connector 20 and the mating connector 30. At the same time, the structure of the protective shell 10 is simple, and only needs to insert the radio frequency coaxial connector 20 into the protective shell 10 during assembly, which is convenient to assemble.

[0039] As shown in Figure 2 As shown, the gap between the clamping arms of the second pair of clamping arms 132 and the plate-shaped support part 110 is also in the thickness direction (Z direction) of the plate-shaped support part 110, so that when the radio frequency coaxial connector 20 is inserted into the protective shell 10, the convex edges 2111 on both sides of the radio frequency coaxial connector 20 can slide into the gap, avoiding the second pair of clamping arms 132 from blocking the sliding of the radio frequency coaxial connector 20.

[0040] As shown in Figure 1As shown, the clamping arms (131a, 131b, 132a, 132b) extend along the length direction (Y direction) or extend in the opposite direction of the length direction (Y direction). This makes the extension direction of the clamping arms parallel to the insertion direction of the RF connector, which is more conducive to the clamping arms clamping the RF coaxial connector 20.

[0041] In one embodiment, if Figure 1 As shown, the clamping arms (131a, 131b) of the first clamping arm pair 131 extend in the longitudinal direction (Y direction), and the clamping arms (132a, 132b) of the second clamping arm pair 132 extend in the opposite direction of the longitudinal direction (Y direction). This allows the bases of the clamping arms of the first clamping arm pair 131 and the second clamping arm pair 132 to be located at the two ends of the plate-shaped support portion 110, respectively, so that the space between the two ends of the plate-shaped support portion 110 can be better utilized to extend the clamping arms.

[0042] like Figure 1 As shown, the clamping arms (131a, 131b) of the first clamping arm pair 131 extend from the side edges of the plate-shaped limiting portion 120 along the length direction (Y direction). Both sides of the plate-shaped limiting portion 120 extend forward to form the first clamping arm pair 131. The first clamping arm pair 131 extends directly from the plate-shaped limiting portion 120, which makes the structure of the protective housing 10 more streamlined.

[0043] like Figure 1 As shown, the roots of the clamping arms ( 132 a , 132 b ) of the second clamping arm pair 132 extend toward the plate-shaped support portion 110 and are connected to the plate-shaped support portion 110 , thereby fixing the second clamping arm pair 132 on the plate-shaped support portion 110 .

[0044] like Figure 1 As shown, the plate-shaped support portion 110 , the plate-shaped limiting portion 120 , the first clamping arm pair 131 and the second clamping arm pair 132 are integrally formed from the same metal plate through processes such as stamping and bending.

[0045] For further reference, Figure 3 As shown, the distance d1 between the roots of the two clamping arms (132a, 132b) of the second clamping arm pair 132 is greater than or equal to the width d2 of the RF coaxial connector 20. Figure 3 As shown, the RF coaxial connector 20 needs to be inserted into the protective housing 10 from between the roots of the two clamping arms of the second clamping arm pair 132. Therefore, the distance d1 between the roots of the two clamping arms (132a, 132b) of the second clamping arm pair 132 is set to be greater than or equal to the width d2 of the RF coaxial connector 20, which facilitates the smooth insertion of the RF coaxial connector 20 into the protective housing 10.

[0046] like Figure 1 As shown, a recessed portion 1301 is provided in the middle portion of the clamping arm and is recessed along the clamping direction. The recessed portion 1301 is used to clamp the RF coaxial connector 20 .

[0047] With reference to the foregoing Figure 1 , the plate-shaped limiting portion 120 is provided with a boss 121. As shown in Figure 4 , the boss 121 is arranged on the surface of the plate-shaped limiting portion 120 against which the radio frequency coaxial connector 20 abuts, and the radio frequency coaxial connector 20 abuts against the boss 121. The boss 121 is arranged on the plate-shaped limiting portion 120 to abut against the radio frequency coaxial connector 20, so that a larger space is provided between the plate-shaped limiting portion 120 and the radio frequency coaxial connector 20, thereby allowing the first pair of clamping arms 131 to extend in a longer space. The clamping arms of the first pair of clamping arms 131 are longer, thereby ensuring the elasticity of the clamping arms and allowing the clamping arms to have a larger clamping force.

[0048] The embodiments of the present application also disclose a radio frequency coaxial connector 20 assembly. As shown in Figure 3 and Figure 4 , the radio frequency coaxial connector 20 assembly comprises the protective shell 10 as above, and further comprises the radio frequency coaxial connector 20 arranged in the protective shell 10.

[0049] The structure of the radio frequency coaxial connector 20 is shown in Figure 5 and Figure 6 , which comprises an outer conductor 210, an insulator 220, a conductive terminal 230 and a cable 240. As shown in Figure 5 , the insulator 220 is arranged in the outer conductor 210. The conductive terminal 230 is arranged in the insulator 220. The cable 240 is electrically connected with the conductive terminal 230.

[0050] As shown in Figure 6 , the conductive terminal 230 comprises a base body 231 and a contact portion 232. The contact portion 232 is arranged at one end of the base body 231. The outer conductor 210 comprises a support main body 211, a cylindrical portion 212 and a clamping arm 213. The support main body 211 extends along the conductive terminal 230 and the cable 240 and can support the conductive terminal 230 and the cable 240. The cylindrical portion 212 extends from the support main body 211 in the thickness direction (Z direction) of the support main body 211 and surrounds the contact portion 232 of the conductive terminal 230. The clamping arm 213 is bent from the support main body 211 towards the cable 240 to clamp the cable 240.

[0051] As shown in Figure 4 , the protective shell 10 and the radio frequency coaxial connector 20 are assembled. After the radio frequency coaxial connector 20 is inserted into the protective shell 10, the plate-shaped limiting portion 120 of the protective shell 10 abuts against the cylindrical portion 212 of the outer conductor 210 of the radio frequency coaxial connector 20, the first pair of clamping arms 131 of the protective shell 10 clamps the two sides of the cylindrical portion 212, and the second pair of clamping arms 132 clamps the clamping arm 213 of the radio frequency coaxial connector 20.

[0052] As shown in Figure 6As shown, the support body 211 of the outer conductor 210 protrudes along the two sides of the X direction to the outer periphery of the cylindrical portion 212, forming the flange 2111 described above. Figure 2 As described above, the gap d is provided between the flange 2111 of the first clamping arm pair 131 of the protective shell 10 and the plate-shaped support portion 110 in the thickness direction (Z direction). As shown in Figure 4 As shown, the protruding portions (flanges 2111) of the support body 211 are clamped into the gap d to limit the movement of the radio frequency coaxial connector 20 in the thickness direction (Z direction), so that the radio frequency coaxial connector 20 is completely fixed in the thickness direction (Z direction) and cannot move.

[0053] As shown in Figure 7 and Figure 8 The radio frequency coaxial connector 20 is used to connect with the mating connector 30 to transmit signals. As shown in Figure 8 As shown, after the radio frequency coaxial connector 20 is inserted into the mating connector 30, the conductive terminal 230 of the radio frequency coaxial connector 20 contacts the inner conductor 310 of the mating connector 30, and the outer conductor 210 of the radio frequency coaxial connector 20 is inserted into the outer conductor 320 of the mating connector 30, achieving shielding and grounding.

[0054] The technical features of the above-described embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above-described embodiments are described, but it should be understood that any combination of the technical features that does not result in a contradiction is within the scope of the present disclosure.

[0055] The above-described embodiments only express the implementation of the present application, and the description is more specific and detailed, but it should not be construed as limiting the scope of the patent application. It should be noted that for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application.
