Description

Technical Field

[0001] This application relates to the field of connector technology, and in particular to a novel SMP connector with an anti-aging structure. Background Technology

[0002] The advantages of SMP connectors are mainly reflected in their small size, light weight, wide bandwidth, and reliable connection. As for applications, the SMP RF connector has an ultra-small interface with the same proportions as the MMCX connector, but can operate in a frequency range up to 40 GHz. It is commonly used in small, high-frequency coaxial modules and provides a push-in and snap-in mating connection.

[0003] A search revealed that CN213151125U discloses a moisture-proof SMP connector. In practical use, a sealing groove is provided between the two connectors. When the two connectors are mated, a sealing ring is placed in the sealing groove. After the two connectors are mated, the sealing ring clamps between the connectors, thereby blocking the gap between the connectors and preventing moisture in the air from entering the mating head and affecting the transmission signal. This increases the practicality of the device. The fixing rings on the connectors are connected to each other by the outer connecting sleeve, which improves the stability of the connection between the connectors and prevents the connectors from loosening.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist that need to be improved: the outer conductor of traditional devices usually uses metal spring claws, which rely on elastic deformation to provide contact pressure. Repeated insertion and removal lead to metal fatigue, decreased elasticity, and increased contact resistance, thereby reducing long-term stress. Utility Model Content

Repeated insertion and removal lead to metal fatigue, decreased elasticity, and increased contact resistance, thereby reducing long-term stress.

[0006] This application provides a novel SMP connector with an anti-aging structure, employing the following technical solution: A novel SMP connector with an anti-aging structure includes an interface housing, a silver-plated outer conductor, a contact-type inner conductor, a rotating outer shell, a telescopic conductive rod, and a flexible on / off assembly. The rotating outer shell is rotatably connected to the opposite side of the interface housing. The silver-plated outer conductor is fixedly connected inside the interface housing. One side of the contact-type inner conductor is inserted into one end of the silver-plated outer conductor.

The silver-plated outer conductor serves as the return path for radio frequency signals and provides electromagnetic shielding. The contact-type inner conductor connects to the silver-plated outer conductor via a floating contact and self-aligns during insertion to reduce wear. The rotating outer casing controls the on / off state through rotational movement, reducing insertion and removal wear. It also works with the internally integrated flexible on / off assembly to achieve dynamic adjustment of contact pressure. The telescopic conductive rod automatically adjusts its length to maintain constant contact pressure when the rotating outer casing moves.

[0007] In one feasible technical solution of this application, the flexible switching component includes a hollow disk, a transmission gear, a transverse screw, an insulating support plate, and a moving contact. The hollow disk is fixedly connected inside the rotating outer casing. The transmission gear is meshed with the inner side of the hollow disk. One side of the transverse screw is fixedly connected to the middle of the transmission gear, and the other side of the transverse screw is rotatably connected to the inner surface of the interface housing. The insulating support plate is fixedly connected to both sides of the contact-type inner conductor. The moving contact is arranged in a ring array on one side of the contact-type inner conductor and is used to insert into the inner side of the silver-plated outer conductor.

[0008] In one feasible technical solution of this application, the silver-plated outer conductor is further provided with a contact socket for docking with the moving contact on the side near the contact-type inner conductor.

[0009] In one feasible technical solution of this application, the interior of the silver-plated outer conductor is further provided with a petal-shaped metal ring for contacting the pin.

[0010] In one feasible technical solution of this application, the inner side of the hollow disk is further provided with an annular rack that meshes with the external teeth of the transmission gear.

[0011] In one feasible technical solution of this application, the outer surface of the rotating outer casing is also adhesively connected with a moisture-proof rubber layer.

[0012] In summary, this application includes at least one of the following beneficial technical effects: The flexible switching component of this device achieves dynamic contact pressure adjustment through the mechanical transmission of a rotating outer casing and a transverse screw, eliminating the need for elastic deformation and avoiding metal fatigue. The cooperation between the moving contact and the flap-shaped metal ring ensures a stable contact area during insertion, reducing resistance fluctuations. Furthermore, the rotating outer casing replaces traditional axial insertion and removal, achieving connection through rotational motion, reducing frictional loss. The inner conductor employs a floating structure for self-alignment, preventing uneven wear. The precise fit between the moving contact and the contact hole ensures uniform force on the contact surface during insertion.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a novel SMP connector with an anti-aging structure. (Refer to...) Figures 1 to 5 The new SMP connector with anti-aging structure includes an interface housing 1, a silver-plated outer conductor 2, a contact inner conductor 3, a rotating outer shell 4, a telescopic conductive rod 5, and a flexible on / off assembly 6. The rotating outer shell 4 is rotatably connected to the opposite side of the interface housing 1. The silver-plated outer conductor 2 is fixedly connected to the inside of the interface housing 1. One side of the contact inner conductor 3 is inserted into one end of the silver-plated outer conductor 2. One end of the telescopic conductive rod 5 is fixedly connected to the middle of the contact inner conductor 3. The flexible on / off assembly 6 is installed inside the rotating outer shell 4. The interface housing 1 provides mechanical support and fixes the internal conductor structure. The silver-plated outer conductor 2 serves as the return path for radio frequency signals and provides electromagnetic shielding. The contact-type inner conductor 3 connects to the silver-plated outer conductor 2 via a floating contact and self-aligns during insertion to reduce wear. The rotating outer housing 4 controls the on / off state through rotational movement, reducing insertion and removal wear. It also works with the internally integrated flexible on / off component 6 to achieve dynamic adjustment of contact pressure. The telescopic conductive rod 5 automatically adjusts its length during the rotation of the outer housing 4 to maintain constant contact pressure.

[0026] Exposed metal parts are prone to oxidation, and humid environments accelerate aging. By combining a silver-plated outer conductor 2 and a gold-nickel alloy inner conductor, the device optimizes its oxidation resistance. The outer surface of the rotating outer casing 4 is covered with a moisture-proof rubber layer 10, which blocks moisture and contaminants, ensuring that the contact resistance remains stable even after long-term use.

[0027] The flexible switching assembly 6 includes a hollow disk 61, a transmission gear 62, a transverse screw 63, an insulating support plate 64, and a moving contact 65. The hollow disk 61 is fixedly connected inside the rotating outer casing 4. The transmission gear 62 is meshed with the inner side of the hollow disk 61. One side of the transverse screw 63 is fixedly connected to the middle of the transmission gear 62, and the other side of the transverse screw 63 is rotatably connected to the inner surface of the interface housing 1. The insulating support plate 64 is fixedly connected to both sides of the contact inner conductor 3. The moving contact 65 is arranged in a ring array on one side of the contact inner conductor 3 and is used to insert into the inner side of the silver-plated outer conductor 2.

[0028] During operation, the rotation should be kept smooth, and rapid and violent rotation should be avoided. Rotation operation replaces the traditional plugging and unplugging, reducing wear.

[0029] The silver-plated outer conductor 2 is also provided with a contact socket 7 for mating with the moving contact 65 on the side near the contact-type inner conductor 3.

[0030] The silver-plated outer conductor 2 also has a petal-shaped metal ring 8 for contacting the pin.

[0031] The silver-plated outer conductor 2, together with the lobe-type metal ring 8, provides a stable RF return path, reduces signal reflection, and lowers insertion loss, making it particularly suitable for millimeter-wave communication, high-speed data transmission, and other scenarios.

[0032] The inner side of the hollow disc 61 is also provided with an annular rack 9 that meshes with the external teeth of the transmission gear 62.

[0033] The outer surface of the rotating outer casing 4 is also adhesively connected with a moisture-proof rubber layer 10.

[0034] The usage process of the novel SMP connector with anti-aging structure according to the embodiments of this application is roughly as follows: Check the integrity of the interface housing 1, ensuring that the surfaces of the silver-plated outer conductor 2 and the contact inner conductor 3 are clean and free of oxidation, and confirm that the moisture-proof rubber layer 10 on the outer surface of the rotating outer housing 4 is intact. During connection, align the connector with the mating interface, hold the rotating outer housing 4 and rotate it clockwise. The rotation causes the hollow disk 61 to rotate synchronously. The annular rack 9 on the inner side of the hollow disk 61 drives the transmission gear 62 to rotate, and the transmission gear 62 drives the transverse screw 63 to move axially. At this time, the movement of the transverse screw 63 pushes the insulating support plate 64 to move the contact inner conductor 3 towards the silver-plated outer conductor 2. The telescopic conductive rod 5 extends accordingly, maintaining a constant contact pressure. The moving contact 65 gradually inserts into the contact socket 7 of the silver-plated outer conductor 2, and the petal-shaped metal ring 8 forms a tight contact with the contact pin. When the rotating outer housing 4 rotates to the limit position, the moving contact 65 is fully engaged with the contact socket 7. The petal-shaped metal ring 8 maintains a stable contact pressure, and the impedance matching of the entire connection path reaches the optimal state. When disconnecting, rotate the outer casing 4 counterclockwise, and all transmission components move in the opposite direction. The moving contact 65 completely separates from the contact socket 7, and the telescopic conductive rod 5 returns to its initial length, achieving the power-off effect.

[0035] The beneficial technical effects of the novel SMP connector with anti-aging structure in this application embodiment are roughly as follows: The flexible switching component 6 of this device achieves dynamic contact pressure adjustment through the mechanical transmission of the rotating outer casing 4 and the transverse screw 63, eliminating the need for elastic deformation and avoiding metal fatigue. The cooperation between the moving contact 65 and the petal-shaped metal ring 8 ensures a stable contact area during insertion, reducing resistance fluctuations. Furthermore, the rotating outer casing 4 replaces the traditional axial insertion and removal, achieving connection through rotational motion, reducing frictional loss. The inner conductor 3 adopts a floating structure for self-alignment, avoiding uneven wear. The precise fit between the moving contact 65 and the contact socket 7 ensures uniform force on the contact surface during insertion. The telescopic conductive rod 5 dynamically adjusts its length to ensure constant contact pressure on the inner conductor, maintaining impedance matching. The outer surface of the rotating outer casing 4 is covered with a moisture-proof rubber layer 10, blocking moisture and contaminants, thus achieving an anti-aging effect.

[0036] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
