[0002] RF coaxial connectors are electrical connectors designed to operate at radio frequencies in the megahertz range. They are typically used with coaxial cables and are designed to maintain the shielding provided by the coaxial design to minimize variations in transmission line impedance at the connection.
[0003] A ring-press RF coaxial connector is an RF connector that uses ring-press technology to achieve a tight connection and seal. This design ensures a tight fit between the coaxial cable and the connector by applying ring pressure, thereby providing excellent electrical performance and mechanical stability.
[0004] For ring-pressure type RF coaxial connectors in high-temperature environments, traditional ring-pressure type RF coaxial connectors rely on pressure to maintain a seal. This sealing method is prone to accelerating the aging of the rubber sealing ring in high-temperature environments, leading to surface hardening and cracking of the sealing ring, thereby shortening the service life of the connector. Therefore, a ring-pressure type RF coaxial connector structure is proposed to address the above problems. Utility Model Content

[0029] Please see Figure 1-7 This utility model provides a technical solution:
[0030] A ring-pressed RF coaxial connector structure includes a male connector 1 and a female connector assembly 3. The male connector 1 has an inlet groove 2 on its lower inner side, an arc groove 4 on its inner side near the inlet groove 2, and a retaining groove 5 on its inner side near the arc groove 4. The female connector assembly 3 is mounted on the left end of the male connector 1. The female connector assembly 3 includes a female connector body 31. A retaining rod 32 is fixedly connected to the outer side of the female connector body 31 near the retaining groove 5. An airbag ring 33 is fixedly connected to one side of the female connector body 31. A spring 34 is fixedly connected to the left side of the female connector body 31 near the airbag ring 33. A protective rubber plate 35 is fixedly connected to the right side of the spring 34. An outer channel 38 is opened inside the female connector body 31. A vent 36 is fixedly connected inside the outer channel 38. A balloon 37 is fixedly connected to the left side of the vent 36. A filter plate 39 is fixedly connected inside the outer channel 38 of the female connector body 31.
[0031] As a further implementation of this solution, the left side of the male connector 1 is in close contact with the right side of the airbag ring 33, and the outer side of the left end of the male connector 1 is in close contact with the outer side of the right end of the female connector body 31. This can improve the stability of the right end of the female connector body 31 inside the left end of the male connector 1 and facilitate the fixing between the female connector body 31 and the male connector 1.
[0032] As a further implementation of this solution, the groove 2 is rectangular, the arc groove 4 is arc-shaped, and the slot 5 is rectangular. The groove 2 penetrates the left end of the male connector 1 and is connected to the inside of the left end of the male connector 1. The arc groove 4 is connected to the inside of the left end of the male connector 1, and the slot 5 is connected to the inside of the left end of the male connector 1. The groove 2, arc groove 4, and slot 5 are connected. The locking rod 32 is cylindrical and engages with the inside of the left end of the slot 5. The locking rod 32 can be inserted into the inside of the groove 2 and can move inside the arc groove 4 and into the inside of the slot 5. The locking rod 32 and the slot 5 are engaged by the elastic force of the female connector assembly 3, which improves the installation efficiency and stability after installation.
[0033] As a further implementation of this solution, the inner side of the airbag ring 33 is hollow, the groove 2 is located in the inner circumference of the airbag ring 33, the number of springs 34 is the same as the number of protective rubber plates 35, the right side of the protective rubber plate 35 is in close contact with the inner side of the right end of the airbag ring 33, under the elastic force of the spring 34, the protective rubber plate 35 can be pushed to quickly expand the airbag ring 33 to the right, so as to achieve the sealing effect between the airbag ring 33 and the male connector 1;
[0034] As a further implementation of this solution, the ventilation cylinder 36 is a hollow cylinder, the inner side of the balloon 37 is hollow, and the inner side of the balloon 37 near the ventilation cylinder 36 has a through hole, the ventilation cylinder 36 is connected to the inside of the balloon 37, the ventilation cylinder 36 is embedded in the inner side of the outer channel 38, the outer channel 38 passes through the outside of the connector female body 31, the number of outer channels 38 is the same as the number of filter plates 39, which facilitates the air inside the airbag ring 33 to enter the balloon 37 for storage, and the sealing of the balloon 37 can prevent the outside air from entering the airbag ring 33. The pressure balance of the outer channel 38 can reduce the resistance of the balloon 37 expansion.
[0035] Workflow: To achieve stable sealing between the male connector 1 and the female connector assembly 3, and to extend the service life of their seal, the male connector 1 is first installed by sliding its left end inside the right end of the female connector body 31. At this point, the outer side of the left end of the male connector 1 is in contact with the outer side of the right end of the female connector body 31. The locking rod 32 of the female connector body 31 is aligned with the groove 2. The male connector 1 is then pressed towards the female connector body 31. When the locking rod 32 is on the right side of the groove 2, the male connector 1 is rotated, causing the locking rod 32 to rotate inside the arc groove 4. When the locking rod 32 reaches the rear end of the arc groove 4, the male connector 1 is released. Under the elastic force of the female connector assembly 3, the locking rod 32 is positioned inside the left end of the groove 5, achieving a quick and secure installation. During this installation process, the left side of the male connector 1 will contact the right side of the airbag ring 33, and the male connector 1 will squeeze against the airbag ring 33. During the compression process, the airbag ring 33 deforms and compresses the protective rubber plate 35. The protective rubber plate 35 can prevent the spring 34 from damaging the airbag ring 33. At the same time, the spring 34 undergoes elastic deformation. At this time, the gas inside the airbag ring 33 enters the balloon 37 from the vent 36. The balloon 37 collides and moves inside the outer channel 38. At this time, the air inside the outer channel 38 will flow out of the connector female body 31. The filter plate 39 plays the role of blocking external impurities. The filter plate 39 can be ventilated. When the connector male 1 is released, under the elastic force of the spring 34 and the return action of the balloon 37, the airbag ring 33 will be tightly attached to the left side of the connector male 1. This not only achieves a stable sealing effect, but also prevents the airbag ring 33 from aging rapidly due to high temperature or compression, ensuring the integrity of the airbag ring 33's appearance, and improving the service life of the seal between the connector male 1 and the connector female assembly 3.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
