[0043] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0044] This application provides a miniature radio frequency connector, specifically a miniature radio frequency connector with a wire end. For example... Figure 3 and Figure 4 As shown, the miniature RF connector 10 includes an outer conductor 100, a center terminal 200, and an insulating base 300. Both the outer conductor 100 and the center terminal 200 are disposed on the insulating base 300, which insulates the outer conductor 100 from the center terminal 200. Figure 3 As shown, the outer conductor 100 surrounds the center terminal 200. When the miniature RF connector 10 is plugged into the corresponding board connector, the outer conductor 100 of the miniature RF connector 10 engages with the outer conductor of the board connector, and the center terminal 200 of the miniature RF connector 10 contacts the center terminal of the board connector, thereby enabling signal transmission.

[0045] In the embodiments of this application, such as Figure 4 As shown, the outer conductor 100 includes two semi-cylindrical units 110, each of which includes a semi-cylindrical portion 111 and a solder foot 112 disposed at the bottom end of the semi-cylindrical portion 111. The two semi-cylindrical portions 111 enclose a cylindrical portion 101 for insertion with a mating connector (board connector). Figure 4 As shown, the inner wall of the cylindrical portion 101 protrudes inward, thereby securing the mating connector. (As indicated...) Figure 4 As shown, the insulating base 300 is provided with a limiting groove 301, and the cylindrical portion 101 is disposed in the limiting groove 301. The shape of the limiting groove 301 is adapted to the cylindrical portion 101, and it is a circular groove, so that the limiting groove 301 can limit the cylindrical portion 101 and prevent it from deforming and failing. It can be understood that, as Figure 4 As shown, the limiting groove 301 has notches 302 on both sides so that the welding foot 112 can be led outward through the notches 302. Figure 4 As shown, the end of the solder leg 112 extends to the side, extending the solder leg 112 to the side, leading out the solder leg 112, and connecting the ends of the two solder legs 112 together.

[0046] In the aforementioned miniature RF connector 10, the outer conductor 100 is innovatively designed as a split structure. The outer conductor 100 includes two semi-cylindrical units 110, which enclose the cylindrical portion 101 of the outer conductor 100. When the connector is engaged, the outer conductor 100 can open outward, increasing its range of motion, thereby reducing stress concentration, avoiding the problem of easy material damage, and extending the service life of the connector.

[0047] Meanwhile, the micro radio frequency connector 10 of the present application has a small number of soldering pins 112, only one soldering pin 112 on each half barrel unit 110, and only two soldering pins 112 on the whole outer conductor 100. Compared with the three soldering pins (112a', 112b', 112c') of the conventional outer conductor 100', the micro radio frequency connector 10 of the present application reduces the number of soldering pins, and stress concentration is prone to occur at the soldering pins. Therefore, reducing the number of soldering pins reduces stress concentration and damage to the material, prolonging the service life of the connector.

[0048] As described in the background, referring to Figure 2 , the conventional outer conductor 100' can only be made in one piece, and the barrel portion 101' of the outer conductor 100' is a closed barrel. The integrity of the whole outer conductor 100' is maintained by the one-piece closed barrel portion 101'. The conventional outer conductor 100' cannot be made in two pieces. If it is made in two pieces, the two half outer conductors 100' will be loose when assembled to the insulating seat 300'. The present application solves this problem. Referring to Figure 4 , the outer conductor 100 is made in two pieces to reduce stress concentration while ensuring the integrity of the outer conductor 100 to prevent it from being loose after being assembled to the insulating seat 300. Specifically, the soldering pins 112 on each half outer conductor 100 are extended outward and connected to each other at the end to maintain the integrity of the whole outer conductor 100. Even if the barrel portion 101 of the outer conductor 100 is a two-piece structure, the integrity of the outer conductor 100 can still be maintained by the mutual connection of the soldering pins, avoiding the outer conductor 100 from being loose when assembled to the insulating seat 300. The innovative design of extending and connecting the soldering pins 112 makes it possible to design the outer conductor 100 in two pieces, replacing the conventional outer conductor 100' which can only maintain the integrity of the whole outer conductor 100' by the one-piece barrel portion 101'. The present application transfers the integrity of the outer conductor 100' from the barrel portion 101' to the soldering pins 112, maintaining the integrity of the outer conductor 100 by connecting the soldering pins 112, thereby liberating the barrel portion 101, which can be made in two pieces. This improves the disadvantages of the one-piece barrel portion 101' structure in the industry and solves the industry pain points.

[0049] Referring to Figure 11 , the first direction T is defined as a direction parallel to the tangent direction of the barrel portion 101. In an embodiment, as shown in Figure 11As shown, the two ends of the solder feet 112 along the first direction T are a first end B1 and a second end B2, respectively. The first end B1 of the solder feet 112 extends beyond the diameter d of the cylindrical portion 101 along the first direction T, and the first ends B1 of the two solder feet 112 are connected. This structural design allows the solder feet 112 to be led out to a position away from the cylindrical portion 101 before being connected. This avoids interference at the connection point of the solder feet 112 with the insertion of the cylindrical portion 101 into the mating connector. Furthermore, this design ensures that the ends of the two solder feet 112 are opposite each other, facilitating their connection.

[0050] It is understandable that the weld leg 112 may not extend beyond the diameter d of the cylindrical portion 101 along the first direction T. For example... Figure 13 As shown, the connection between the solder feet 112 can be an arc-shaped connection around the cylindrical portion 101, thus eliminating the need to extend the solder feet 112 before connection. However, this structure is difficult to form and has relatively poor structural performance. Figure 11 The structure shown is also inferior. Therefore, the preferred option is... Figure 11 The method shown is to extend the solder foot 112 beyond the diameter d range of the cylindrical portion 101 along the first direction T before reconnecting it.

[0051] like Figure 11 As shown, the connecting part between the two solder feet 112 can be a connecting rod 113. The two ends of the connecting rod 113 are connected to the solder feet 112 respectively. The outer conductor 100 is integrally cut and stamped from a metal sheet; therefore, the cylindrical portion 101, solder feet 112, and connecting rod 113 of the outer conductor 100 are all integrally formed structures. The connecting rod 113 is sheet-like and extends from one solder foot 112 to the other. The connecting rod 113 ensures the connection between the two semi-cylindrical units 110. The connecting rod 113 not only prevents the two semi-cylindrical units 110 from becoming loose when the outer conductor 100 is assembled to the insulating base 300, but also provides constraint for the two semi-cylindrical portions 111 when they open, preventing them from opening excessively.

[0052] refer to Figure 11 As mentioned above, the first end B1 of the solder leg 112 extends along the first direction to a position away from the cylindrical portion 101 before connecting the first ends B1 of the two solder legs 112. This ensures that the connecting rod 113 is spaced a distance S1 from the cylindrical portion 101, thereby preventing the connecting rod 113 from interfering with the insertion of the cylindrical portion 101 and the mating connector. The distance S1 between the connecting rod 113 and the cylindrical portion 101 can be adjusted as needed, for example, it can be 0.2mm-0.9mm.

[0053] In one embodiment, such as Figure 8As shown, the solder leg 112 includes a connecting portion 1121 and a plate portion 1122. The connecting portion 1121 extends from the bottom end of the half-cylinder portion 111 to the outside of the cylindrical portion 101 in the direction axially away from the cylindrical portion 101. As shown, Figure 10 As shown, the direction axially away from the cylindrical portion 101 is downward. As shown, Figure 10 The connecting portion 1121 extends downward and outward from the bottom end of the half-cylinder portion 111, thereby leading the solder leg 112 from the bottom end of the cylindrical portion 101 to the two sides below the cylindrical portion 101. As shown, Figure 11 As shown, the plate portion 1122 extends from the connecting portion 1121 in the first direction T, thereby extending the end of the solder leg 112 to a position away from the cylindrical portion 101 and opposite the ends of the two solder legs 112, facilitating the connection of the two solder legs 112.

[0054] As shown in Figure 3 and Figure 7 As shown, the insulating seat 300 is clamped between the bottom end of the half-cylinder portion 111 and the top end of the plate portion 1122, thereby fixing the outer conductor 100 on the insulating seat 300. Specifically, as shown, Figure 7 As shown, the half-cylinder portion 111 is located in the limiting groove 301 on the insulating seat 300, and the bottom end face C1 of the half-cylinder portion 111 abuts against the groove bottom of the limiting groove 301; the top end face C2 of the plate portion 1122 of the solder leg 112 abuts against the bottom of the insulating seat 300, thereby clamping the insulating seat 300 between the bottom end C1 of the half-cylinder portion 111 and the top end C2 of the plate portion 1122.

[0055] As shown, Figure 8 The first ends B1 of the plate portions 1122 of the two solder legs 112 are connected. The plate portion 1122 is relatively flat and straight, with more space, and is easier to connect than other parts on the outer conductor. As shown, Figure 8 The connecting rod 113 is connected between the first ends B1 of the two plate portions 1122.

[0056] As shown, Figure 4 The top of the insulating seat 300 is provided with a limiting step surface 303 for limiting the connecting rod 113, and the connecting rod 113 abuts against the limiting step surface 303. The limiting step surface 303 is provided on the insulating seat 300 to limit the connecting rod 113, which can further limit the outer conductor 100 through the connecting rod 113, so that the outer conductor 100 is more stably assembled on the insulating seat 300, preventing the outer conductor 100 from moving.

[0057] As shown, Figure 9 In an embodiment, the connecting rod 113 is arched upward compared to the plate portion 1122. As shown, Figure 4 and Figure 5The bottom of the connecting rod 113 and the side wall of the connecting rod 113 close to the cylindrical portion 101 abut against the insulating seat 300 and are grounded on the stepped surface 303 of the insulating seat 300. Figure 4 As shown in FIG. 13, the connecting rod 113 forms a frame shape between the connecting rod 113 and the first end B1 of the two solder pins 112, and the frame is on the insulating seat 300, thereby playing a better limiting role. In the embodiment of the application, the connecting rod 113 is arranged to be arched upward, so that the increase of the connecting rod 113 does not interfere with the assembly of the outer conductor 100. The outer conductor 100 is still assembled from top to bottom on the insulating seat 300 as in the previous conventional assembly manner, and the connecting rod 113 is directly clamped on the top of the insulating seat 300.

[0058] As shown in FIG. 13, the connecting rod 113 forms a frame shape between the connecting rod 113 and the first end B1 of the two solder pins 112, and the frame is on the insulating seat 300, thereby playing a better limiting role. In the embodiment of the application, the connecting rod 113 is arranged to be arched upward, so that the increase of the connecting rod 113 does not interfere with the assembly of the outer conductor 100.

Figure 12 As shown in FIG. 13, the connecting rod 113 forms a frame shape between the connecting rod 113 and the first end B1 of the two solder pins 112, and the frame is on the insulating seat 300, thereby playing a better limiting role. In the embodiment of the application, the connecting rod 113 is arranged to be arched upward, so that the increase of the connecting rod 113 does not interfere with the assembly of the outer conductor 100. The outer conductor 100 is still assembled from top to bottom on the insulating seat 300 as in the previous conventional assembly manner, and the connecting rod 113 is directly clamped on the top of the insulating seat 300. Figure 2 As shown in FIG. 13, the connecting rod 113 forms a frame shape between the connecting rod 113 and the first end B1 of the two solder pins 112, and the frame is on the insulating seat 300, thereby playing a better limiting role. In the embodiment of the application, the connecting rod 113 is arranged to be arched upward, so that the increase of the connecting rod 113 does not interfere with the assembly of the outer conductor 100.

In the embodiment of the application, the connecting rod 113 is arranged to be arched upward, so that the increase of the connecting rod 113 does not interfere with the assembly of the outer conductor 100. The outer conductor 100 is still assembled from top to bottom on the insulating seat 300 as in the previous conventional assembly manner, and the connecting rod 113 is directly clamped on the top of the insulating seat 300. Figure 8 Figure 10 As shown in FIG. 13, the connecting rod 113 forms a frame shape between the connecting rod 113 and the first end B1 of the two solder pins 112, and the frame is on the insulating seat 300, thereby playing a better limiting role. In the embodiment of the application, the connecting rod 113 is arranged to be arched upward, so that the increase of the connecting rod 113 does not interfere with the assembly of the outer conductor 100. The outer conductor 100 is still assembled from top to bottom on the insulating seat 300 as in the previous conventional assembly manner, and the connecting rod 113 is directly clamped on the top of the insulating seat 300. Figure 4 As shown in FIG. 13, the connecting rod 113 forms a frame shape between the connecting rod 113 and the first end B1 of the two solder pins 112, and the frame is on the insulating seat 300, thereby playing a better limiting role. In the embodiment of the application, the connecting rod 113 is arranged to be arched upward, so that the increase of the connecting rod 113 does not interfere with the assembly of the outer conductor 100. The outer conductor 100 is still assembled from top to bottom on the insulating seat 300 as in the previous conventional assembly manner, and the connecting rod 113 is directly clamped on the top of the insulating seat 300.

In the embodiment of the application, the connecting rod 113 is arranged to be arched upward, so that the increase of the connecting rod 113 does not interfere with the assembly of the outer conductor 100. The outer conductor 100 is still assembled from top to bottom on the insulating seat 300 as in the previous conventional assembly manner, and the connecting rod 113 is directly clamped on the top of the insulating seat 300.

[0060] As shown in FIG. 13, the connecting rod 113 forms a frame shape between the connecting rod 113 and the first end B1 of the two solder pins 112, and the frame is on the insulating seat 300, thereby playing a better limiting role. In the embodiment of the application, the connecting rod 113 is arranged to be arched upward, so that the increase of the connecting rod 113 does not interfere with the assembly of the outer conductor 100. The outer conductor 100 is still assembled from top to bottom on the insulating seat 300 as in the previous conventional assembly manner, and the connecting rod 113 is directly clamped on the top of the insulating seat 300. Figure 4 Figure 7 As shown in FIG. 13, the connecting rod 113 forms a frame shape between the connecting rod 113 and the first end B1 of the two solder pins 112, and the frame is on the insulating seat 300, thereby playing a better limiting role.

[0061] ​​As shown in Figure 11 The flange 1122a is spaced apart from the connecting rod 113 by a distance S2. This avoids the connecting rod 113 affecting the elasticity of the flange 1122a, and ensures that the flange 1122a has sufficient elasticity to be smoothly clamped under the boss 304.

[0062] As shown in Figure 8 The two half-cylinder portions 111 have a gap H therebetween. The gap H is provided between the two half-cylinder portions 111 so that the two half-cylinder portions 111 do not contact each other and do not restrict the movement of each other, and the clamping space is larger. As shown in Figure 8 Each half-cylinder portion 111 is C-shaped, and the two half-cylinder portions 111 substantially form a cylinder. The two ends of the C-shaped two half-cylinder portions 111 are provided with a gap H.

[0063] In an embodiment, as shown in Figure 4 The center terminal 200 includes a contact portion 210 and a terminal leg 220. As shown in Figure 3 The center terminal 200 is embedded in the insulating seat 300 and integrally injection molded with the insulating seat 300. As shown in Figure 3 The contact portion 210 of the center terminal 200 is arranged at the center of the cylindrical portion 101 of the outer conductor 100, and the terminal leg 220 of the center terminal 200 extends out of the insulating seat 300 between the second ends B2 of the two soldering legs 112, so as to facilitate soldering the terminal leg 220 of the center terminal 200 to an external device.

[0064] The forming process of the micro radio frequency connector 10 is as follows:

[0065] The center terminal 200 is stamped and formed;

[0066] The center terminal 200 and the insulating seat 300 are integrally injection molded;

[0067] The outer conductor 100 is stamped and formed;
