The magnetic ring 113 is connected in series with the inner core 111. The inner core shell 112 is sleeved on the outer side of the inner core 111. One end of the inner core 111 passes through the inner core shell 112 to the outside of the inner core shell 112. The connector shell 120 is sleeved on the outer side of the inner core component 110 so that the magnetic ring 113 is accommodated in the connector shell 120.

At present, the RF connector 100 generally adopts an integrated structure, that is, the inner core 111 and the connector shell 120 are integrated. When adding other components such as a magnetic ring 113 to the RF connector 100, only an external module can be added to the outside of the connector shell 120, thereby increasing the volume and weight of the RF connector 100.

[0032] The present application provides a novel RF connector 100, which includes an inner core component 110 and a connector shell 120.

[0033] In the present application, the magnetic ring 113 is connected in series to the inner core 111, and the inner core shell 112 is sleeved on the outer side of the inner core 111 to protect the inner core 111. The magnetic ring 113, the inner core 111 and the inner core shell 112 form the inner core assembly 110, and the inner core assembly 110 is arranged inside the connector shell 120. The connector shell 120 protects the inner core assembly 110 to prevent the inner core assembly 110 from being easily damaged by direct contact with the outside world, and facilitates the connection of the inner core assembly 110 with other structures. In the present application, the connector shell 120 and the inner core 111 of the RF connector 100 are designed to be separated, so that the magnetic ring 113 is assembled inside the RF connector 100, which reduces the weight and volume of the RF connector 100, and has a simple structure and convenient installation and disassembly.

[0034] In one embodiment, referring to Figure 1 , Figure 3 , Figure 5 and Figure 7As shown, the inner core outer shell 112 includes a first outer shell 1121 and a second outer shell 1122, the first outer shell 1121 and the second outer shell 1122 are spaced apart on the outer side of the inner core 111, and the magnetic ring 113 is located between the first outer shell 1121 and the second outer shell 1122, and is sleeved on the outer side of the inner core 111 and connected in series with the inner core 111. Specifically, the magnetic ring 113 is sleeved on the outside of the inner core 111 and connected in series with the inner core 111, and the inner core outer shell 112 is also sleeved on the outside of the inner core 111; the inner core outer shell 112 is set into two parts, that is, the inner core outer shell 112 includes a first outer shell 1121 and a second outer shell 1122, the first outer shell 1121 and the second outer shell 1122 are spaced apart on both sides of the inner core 111, and the magnetic ring 113 is arranged in the middle of the inner core 111, that is, the magnetic ring 113 is located between the first outer shell 1121 and the second outer shell 1122. The first shell 1121, the second shell 1122 and the magnetic ring 113 together wrap the inner core 111, so that the inner core 111 is not easily damaged, and the assembly method of the first shell 1121, the second shell 1122 and the magnetic ring 113 is simple; the magnetic ring 113 is sleeved on the inner core 111 and is located between the first shell 1121 and the second shell 1122, so that the volume of the inner core component 110 is smaller, so as to reduce the volume of the RF connector 100.

[0035] In a specific embodiment, refer to Figure 3 , Figure 5 and Figure 7As shown, the first shell 1121 includes a protrusion 11211, which protrudes along the circumference of the first shell 1121 in a direction away from the inner core 111, and the connector shell 120 includes an inner flange 121; wherein, when the connector shell 120 is sleeved on the outside of the inner core assembly 110, the protrusion 11211 abuts against the inner flange 121. Specifically, the first shell 1121 is sleeved on the outside of the inner core 111, and the first shell 1121 is located on one side of the inner core 111, the protrusion 11211 is protruded along the circumference of the first shell 1121 in the direction away from the inner core 111, and the diameter from the edge of the protrusion 11211 to the center of the first shell 1121 is larger than the diameter from the edges of both ends of the first shell 1121 to the center of the first shell 1121; the inner flange 121 of the connector shell 120 protrudes toward the inside of the connector shell 120 along the edge of the connector shell 120, and the inside of the connector shell 120 is in a connected state; when the inner core assembly 110 is installed in the connector shell 120, one end of the first shell 1121 passes through the inner flange 121 of the connector shell 120, and until the protrusion 11211 of the first shell 1121 abuts against the inner flange 121 of the connector shell 120, at which time the inner core assembly 110 can no longer move forward. Therefore, the protrusion 11211 and the inner flange 121 limit the assembly position of the inner core component 110 and the connector shell 120, preventing the inner core component 110 from passing through the other end of the connector shell 120 from one end of the connector shell 120, causing the inner core component 110 to protrude out of the connector shell 120.

[0036] In one embodiment, referring to Figures 1 to 7As shown, the RF connector 100 includes a PCBA assembly 130 , and one side of the PCBA assembly 130 is fixedly connected to the inner core 111 , the inner core shell 112 , and the connector shell 120 , respectively.

In this embodiment, the side of the second shell 1122 away from the first shell 1121 is fixedly connected to the PCBA assembly 130; the two ends of the connector shell 120 are respectively fixedly connected to the two ends of the PCBA assembly 130; in this embodiment, the inner core 111, the inner core shell 112 and the connector shell 120 are fixedly connected to the PCBA assembly 130 by welding; therefore, the inner core 111 is welded and connected to the PCBA assembly 130, and the inner core shell 112 and the connector shell 120 are welded and grounded to the PCBA assembly 130. The RF connector 100 of the present embodiment adopts a double grounding form, that is, the connector housing 120 and the inner core housing 112 are both grounded to the PCBA assembly 130, thereby effectively suppressing the ground-level surface current and separating the ground current; compared with the RF connector 100 of the traditional technology that only uses the connector housing 120 for grounding, the inner core housing 112 needs to be grounded by sliding through the connector housing 120, which has problems such as large contact impedance and instantaneous poor contact leading to poor grounding. The double grounding form of the RF connector 100 in the present embodiment is reliable and effective, avoiding the problem of poor grounding of the RF connector 100.

In this embodiment, the sleeve assembly 140 is a cylindrical structure with a hollow center, so as to facilitate covering a portion of the connector housing 120 and the PCBA assembly 130 . The sleeve assembly 140 is made of POM plastic material.

Specifically, the sleeve assembly 140 and the connector housing 120 are both hollow cylindrical structures in the middle, so a thread 500 is provided on the inner wall of the sleeve assembly 140 on the side close to the connector housing 120, and a thread 500 is correspondingly provided on the outer side of the connector housing 120, and the outer side of the connector housing 120 refers to the side of the connector housing 120 away from the inner core 111; when the sleeve assembly 140 is inserted into the connector housing 120, the thread 500 on the inner wall of the sleeve assembly 140 is locked with the thread 500 on the outer side of the connector housing 120, so as to realize the fixing of the sleeve assembly 140 and the connector housing 120, and the fixing method using the thread 500 lock is a hard connection, which is safe and reliable, and is easy to install and disassemble, and has high work efficiency.

[0040] In particular, the connector housing 120 in this embodiment has a structure that is larger at the top and smaller at the bottom, that is, the diameter of the front portion of the connector housing 120 is larger than the diameter of the rear portion.
