[0038] An existing radio frequency connector for an automobile includes a sleeve component, an outer conductor, an insulator, an inner conductor and an insulating shell. The sleeve is sleeved on the rear end of the insulating member and is in electrical contact with the outer conductor to achieve stable connection between the internal structures of the insulating shell. However, this solution requires more parts and complex assembly, thus reducing the production efficiency and increasing the processing cost.

[0039] To solve the above problems, the present utility model proposes a radio frequency connector 1, which includes an insulating shell 10, an outer conductor 20, an insulator 30, and an inner conductor 40. The outer conductor 20 includes a plug-in portion 21 and a main body portion 22 that are connected to each other. A first elastic piece 221 is formed on the circumferential side of one end of the main body portion 22 close to the plug-in portion 21. A positioning step 31 is provided on the circumferential side of the corresponding installation position of the insulator 30. When the insulator 30 is inserted into the outer conductor 20, the first elastic piece 221 abuts against the end face of the positioning step 31 facing the plug-in portion 21, playing a role of stopping advancement, ensuring stable installation between the two, without the need to add other parts, being simple in assembly while reducing the use of parts and lowering the processing cost.

[0040] As Figures 1 to 4 shown, in an embodiment, the radio frequency connector 1 includes an insulating shell 10, an outer conductor 20, an insulator 30, and an inner conductor 40. The outer conductor 20 includes a plug-in portion 21 and a main body portion 22 that are connected to each other. The outer conductor 20 is installed in the insulating shell 10. The plug-in portion 21 is used to connect to an external male end. The main body portion 22 is provided with a hollow interior. A first elastic piece 221 is formed on the circumferential side of one end of the main body portion 22 close to the plug-in portion 21; the first elastic piece 221 is bent towards the middle of the main body portion 22. A positioning step 31 is provided on the circumferential side of the insulator 30. The insulator 30 is inserted into the outer conductor 20, and the first elastic piece 221 abuts against the end face of the positioning step 31 facing the plug-in portion 21; the inner conductor 40 is inserted into the insulator 30, one end is used to connect to the inner conductor of the external male end, and the other end is connected to a cable 60.

[0041] In this embodiment, the material of the insulating shell 10 can be selected as plastic or plastic rubber, so that it has good mechanical properties and insulating properties, thereby protecting the internal components. The outer conductor 20 includes a plug-in portion 21 and a main body portion 22 made by an integrated design. The plug-in portion 21 is the front end of the outer conductor 20. The structural design of the plug-in portion 21 can be closely matched with the jack portion of the external male end to ensure good electrical connection. The shape and size of the plug-in portion 21 are determined according to specific connector standards to ensure compatibility with the corresponding male end. The insulator 30 is coaxially arranged with the outer conductor 20 and is inserted into the outer conductor 20. When the insulator 30 is inserted into the designated position inside the outer conductor 20, the end face of the positioning step 31 abuts against the first elastic piece 221. At this time, the insulator 30 cannot continue to move inside the outer conductor 20, playing a role of stopping advancement, thereby improving the installation stability between the two. The inner conductor 40 is coaxially arranged with the insulator 30 and is inserted into the insulator 30. The front end of the inner conductor 40 is located inside the plug-in portion 21 to facilitate connection to the inner conductor 40 of the external male end, and the rear end is connected to a cable 60 for transmitting radio frequency signals.

[0042] The present utility model provides a radio frequency connector 1, which includes an insulating housing 10, an outer conductor 20, an insulator 30, and an inner conductor 40. The outer conductor 20 includes a plugging portion 21 and a main body portion 22 that are connected. A first elastic piece 221 is formed on the circumferential side of one end of the main body portion 22 close to the plugging portion 21. A positioning step 31 is provided on the circumferential side of the corresponding installation position of the insulator 30. When the insulator 30 is inserted into the outer conductor 20, the first elastic piece 221 abuts against the end face of the positioning step 31 facing the plugging portion 21, playing a role of stopping advancement, ensuring stable installation between the two, without the need to add other parts, being simple in assembly while reducing the use of parts and lowering the processing cost.

[0043] As Figures 1 to 4 , in an embodiment, a plurality of first elastic pieces 221 are provided. The plurality of first elastic pieces 221 are arranged at intervals along the circumferential direction of the outer conductor 20, and the plurality of first elastic pieces 221 all abut against the end face of the positioning step 31 facing the plugging portion 21.

[0044] In this embodiment, in order to further improve the installation stability between the outer conductor 20 and the insulator 30, a plurality of first elastic pieces 221 are provided at intervals along the circumferential direction of the outer conductor 20. When the insulator 30 is inserted into the specified position inside the outer conductor 20, the above-mentioned plurality of first elastic pieces 221 uniformly abut against the end face of the positioning step 31. Compared with the single first elastic piece 221 abutting against the end face of the positioning step 31, the design of the plurality of first elastic pieces 221 provides multi-point contact, increases the contact area, realizes the circumferential positioning between the outer conductor 20 and the insulator 30, further improves the installation stability between the two, and at the same time, if one of the first elastic pieces 221 is damaged, the outer conductor 20 and the insulator 30 can still maintain a stable connection, improving the use safety of the radio frequency connector 1.

[0045] As Figure 4 , in an embodiment, a convex portion 23 is provided inside the main body portion 22, and a groove 32 is correspondingly formed on the circumferential side of the insulator 30. When the insulator 30 is inserted into the outer conductor 20, the convex portion 23 is inserted into the groove 32.

[0046] In this embodiment, after the insulator 30 is inserted into the specified position inside the outer conductor 20, a convex portion 23 that is convex inward relative to the outer wall of the main body portion 22 is formed by riveting on the outer wall of the main body portion 22 through a tool. At the same time, the convex portion 23 is clamped in the groove 32 correspondingly formed on the circumferential side of the insulator 30 to prevent the insulator 30 from disengaging from the inside of the outer conductor 20, playing a role of stopping retraction.

[0047] Through the clamping of the convex portion 23 and the groove 32 in this embodiment and the clamping of the first elastic piece 221 and the end face of the positioning step 31 in the above embodiment, the two-way fixation between the outer conductor 20 and the insulator 30 is realized, further improving the installation stability between the two, and thus improving the use safety of the radio frequency connector 1.

[0048] As Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 , in one embodiment, a stepped hole is axially formed in the insulator 30 along its own axis. The stepped hole sequentially includes a first through hole 33, a second through hole 34, and a third through hole 35 that are connected and communicated in a direction away from the insertion portion. A second elastic piece 42 is disposed outside the inner conductor 40, and the second elastic piece 42 is bent in a direction away from the center of the inner conductor 40; the inner conductor 40 is inserted into the insulator 30, and the second elastic piece 42 abuts against the hole wall of the first through hole 33.

[0049] In this embodiment, to adapt to different sizes of the inner conductor 40 at different positions and other components connected to the rear end of the inner conductor 40, the interior of the insulator 30 sequentially includes three connected through holes in a direction away from the insertion portion 21: a first through hole 33, a second through hole 34, and a third through hole 35. The diameter of each through hole is different, forming a stepped shape, so as to correspond to different parts of the inner conductor 40 and the components connected to the rear end of the inner conductor 40. The design of the stepped hole optimizes the installation space inside the insulator 30 and improves the installation convenience between the inner conductor 40 and the insulator 30.

[0050] At the same time, in order to further improve the installation stability between the inner conductor 40 and the insulator 30, a first opening structure 41 is formed in the portion of the inner conductor 40 located in the first through hole 33, and a second elastic piece 42 is connected to one side wall of the first opening structure 41. The setting of the first opening structure 41 improves the connection strength between the second elastic piece 42 and the inner conductor 40. After the inner conductor 40 is inserted into the designated position inside the insulator 30, the second elastic piece 42 elastically abuts against the hole wall of the first through hole 33, preventing the inner conductor 40 from detaching from inside the insulator 30 and achieving an anti-retreat effect. At the same time, the elastic force of the second elastic piece 42 can also prevent relative displacement between the inner conductor 40 and the insulator 30 due to vibration or impact during the use of the RF connector 1, improving the practicality of the RF connector 1.

[0051] As Figure 7 and Figure 8 , in one embodiment, a clamping portion 43 is convexly provided on the outer peripheral side of the inner conductor 40. The clamping portion 43 is disposed at one end of the inner conductor 40 close to the second elastic piece 42. The inner conductor 40 is inserted into the insulator 30, and the clamping portion 43 abuts against the end surface between the first through hole 33 and the second through hole 34.

[0052] In this embodiment, the inner conductor 40 is further provided with a clamping portion 43 in a wing shape. The clamping portion 43 and the main body structure of the inner conductor 40 are integrally designed and manufactured. After the inner conductor 40 is inserted into the designated position inside the insulator 30, the clamping portion 43 abuts against the end face between the first through hole 33 and the second through hole 34, preventing the inner conductor 40 from being damaged due to excessive insertion, achieving a stop effect. At the same time, the clamping portion 43 increases the contact area between the inner conductor 40 and the insulator 30, thereby improving the connection stability.

[0053] Through the clamping of the clamping portion 43 and the end face between the first through hole 33 and the second through hole 34 in this embodiment and the elastic abutment of the second elastic piece 42 and the inner wall of the first through hole 33 in the above embodiment, the two-way fixation between the insulator 30 and the inner conductor 40 is realized, further improving the installation stability of the internal structure of the RF connector 1.

[0054] Such as Figure 2 、 Figure 3 and Figure 9 In one embodiment, a first positioning ring 24 is provided on the outer side of the outer conductor 20, and a convex rib 11 is provided inside the insulating shell 10. When the outer conductor 20 is inserted into the insulating shell 10, one side of the first positioning ring 24 close to the insertion portion 21 abuts against the convex rib 11.

[0055] In this embodiment, a first positioning ring 24 is circumferentially provided on the outer side of the outer conductor 20. Correspondingly, a convex rib 11 is provided inside the insulating shell 10. The convex rib 11 is provided on the inner wall of the insulating shell 10, and its position and shape match those of the first positioning ring 24. When the outer conductor 20 is inserted into the insulating shell 10, one side of the first positioning ring 24 close to the insertion portion 21 will abut against the convex rib 11, preventing the outer conductor 20 from being damaged due to excessive insertion and playing a stop role. At the same time, the cooperation between the first positioning ring 24 and the convex rib 11 ensures the precise position of the outer conductor 20 inside the insulating shell 10, reduces the assembly error, and improves the assembly consistency of the RF connector 1.

[0056] Such as Figure 2 、 Figure 3 and Figure 9 In one embodiment, a second positioning ring 25 is further provided on the outer side of the outer conductor 20. The first positioning ring 24 and the second positioning ring 25 are spaced apart in the direction away from the insertion portion 21. A first locking member 12 is further provided inside the insulating shell 10. One end of the first locking member 12 is fixedly connected to the insulating shell 10, and the other end extends towards the inside of the insulating shell 10;

[0057] When the outer conductor 20 is inserted into the insulating shell 10, the first locking member 12 abuts against the side of the second positioning ring 25 away from the first positioning ring 24.

[0058] In this embodiment, in addition to the first positioning ring 24 provided on the outer side of the outer conductor 20, a second positioning ring 25 is further added. The two positioning rings are arranged at intervals along the direction away from the insertion part 21, forming a multiple positioning system, which jointly ensures the correct position of the outer conductor 20 within the insulating housing 10. The first locking member 12 is a hanging elastic piece, one end of which is integrally designed with the insulating housing 10 and can swing relative to the insulating housing 10 itself. During the process of inserting the outer conductor 20 into the insulating housing 10, the outer conductor 20 pushes open the first locking member 12 and moves towards the inside of the insulating housing 10. When the outer conductor 20 is inserted into the designated position inside the insulating housing 10, the first locking member 12 drops and abuts against the end face of the second positioning ring 25 to prevent the outer conductor 20 from accidentally falling off the insulating housing 10, achieving an anti-retreat effect and further improving the installation stability between the outer conductor 20 and the insulating housing 10.

[0059] In addition, in this embodiment, a third positioning ring 26 is further provided on the outer side of the outer conductor 20. The third positioning ring 26 is located on the side of the second positioning ring 25 away from the insertion part 21. The setting of the third positioning ring 26 further improves the connection strength between the outer conductor 20 and the insulating housing 10, enhances the overall durability of the RF connector 1, and enables it to withstand more frequent plugging and unplugging operations and harsher working environments.

[0060] Such as Figure 1 , Figure 2 and Figure 9 , in one embodiment, the RF connector 1 further includes a second locking member 50. The insulating housing 10 is provided with a mounting hole 13. The second locking member 50 includes a cover plate 51 and pins 52 connected to one surface of the cover plate 51. When the outer conductor 20 is inserted into the insulating housing 10, the cover plate 51 covers the mounting hole 13, and the pins 52 are inserted between the first positioning ring 24 and the second positioning ring 25.

[0061] In this embodiment, in order to further enhance the safety and stability of the RF connector 1, the RF connector 1 further includes a second locking member 50. The insulating housing 10 is correspondingly provided with a second mounting hole 13. After the outer conductor 20 is inserted into the designated position inside the insulating housing 10, the pins 52 are inserted between the first positioning ring 24 and the second positioning ring 25, and at the same time the cover plate 51 covers the mounting hole 13 to ensure sealing. The setting of the second locking member 50 provides an additional fixing force between the outer conductor 20 and the insulating housing 10, further ensuring the stability of the connector in frequent plugging and unplugging and vibration environments, and at the same time making the disassembly and maintenance of the RF connector 1 more convenient and reducing the maintenance cost.

[0062] Such as Figure 3, in one embodiment, third elastic pieces 212 are circumferentially arranged on the insertion part 21. The third elastic pieces 212 are integrally formed with the insertion part 21. One end of the third elastic piece 212 is connected to the insertion part 21, and the other end is used to contact the male end outer conductor to achieve conduction.

[0063] In this embodiment, the third elastic piece 212 and the main body of the insertion part 21 are integrally designed and manufactured. Compared with the split design of the third elastic piece 212 and the insertion part 21, the design method in this embodiment improves the insertion strength of the insertion part 21. At the same time, a second opening structure 211 is provided on the insertion part. One end of the third elastic piece 212 is connected to the second opening structure 211, and the other end is a free end. The setting of the second opening structure 211 improves the connection strength between the third elastic piece 212 and the insertion part 21, ensuring that a reliable electrical connection can be provided when the RF connector 1 contacts the male end outer conductor, and thus ensuring the smooth transmission of RF signals.

[0064] Such as Figure 2 and Figure 4 , in one embodiment, the RF connector 1 further includes a wire clamp 70. The wire clamp 70 is sleeved on the cable 60 and connected to one end of the main body part 22 away from the insertion part 21.

[0065] In this embodiment, the cable 60 is composed of a coaxial cable, twisted pair or other suitable transmission media with good RF transmission characteristics. One end of the cable 60 is electrically connected to the RF connector 1, and the other end is connected to other external devices for transmitting RF signals. The wire clamp 70 is tightly sleeved around the cable 60 by a clamping method to ensure that the cable 60 will not move inside or outside the connector, and at the same time makes the installation and replacement of the cable 60 more convenient and reduces the complexity of maintenance. In addition, the combination of the cable 60 and the wire clamp 70 can be selected and customized according to different application requirements to adapt to various RF transmission environments, thereby improving the practicability of the RF connector 1.

[0066] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention.
