Description

Technical Field

[0001] The utility model relates to a new type of high-temperature resistant radio frequency connector, belonging to the technical field of radio frequency connectors. Background Art

[0002] A radio frequency connector is an electronic component used for radio frequency signal transmission, and is widely used in fields such as communication equipment, radio equipment, microwave equipment, and aerospace. They can provide reliable electrical connections in the high-frequency range, usually having low insertion loss and reflection loss. The designs of radio frequency connectors are diverse, including coaxial connectors, waveguide connectors, etc., which can meet the frequency and power requirements of different systems and ensure the stability and performance of signal transmission.

[0003] For example, the publication number CN209981524U discloses a radio frequency connector, which includes a housing, and a counterweight is detachably installed on the rear end face of the housing. For the above radio frequency connector, by installing a counterweight on the rear end face of the housing, the weight of the threaded head is balanced, the function of balancing the center of gravity is realized, and the processing accuracy is improved; the detachable connection between the counterweight and the housing is not only convenient for installation and disassembly, but also the removed counterweight can be recycled, thereby saving processing costs.

[0004] This radio frequency connector lacks a high-temperature resistant structure, resulting in an unsatisfactory overall high-temperature resistant effect, which will cause a significant decline in its performance in a high-temperature environment, including problems such as unstable signal transmission, poor electrical contact, and failure of insulating materials. This will not only seriously affect the stability and reliability of the communication system, but may also lead to equipment damage, data loss, and even system paralysis, bringing great inconvenience and safety hazards to use.

[0005] Therefore, a new type of high-temperature resistant radio frequency connector is proposed. Summary of the Utility Model

[0006] In view of this, the utility model provides a new type of high-temperature resistant radio frequency connector to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0007] The technical solution of the utility model is realized as follows: A new type of high-temperature resistant radio frequency connector includes a radio frequency connector body, and the radio frequency connector body includes a tungsten copper alloy inner conductor, a first functional layer, and a second functional layer. The first functional layer includes a titanium alloy contact part and an LCP insulating layer, and the second functional layer includes a nickel-based alloy shielding layer and an alumina ceramic housing.

[0008] Further preferably, the first functional layer is disposed on the outer surface of the tungsten copper alloy inner conductor, and the second functional layer is disposed on the outer surface of the first functional layer.

[0009] Further preferably, the titanium alloy contact is disposed on the outer surface of the tungsten copper alloy inner conductor, and the LCP insulating layer is disposed on the outer surface of the titanium alloy contact.

[0010] Further preferably, the nickel-based alloy shielding layer is disposed on the outer surface of the LCP insulating layer, and the alumina ceramic housing is disposed on the outer surface of the nickel-based alloy shielding layer.

[0011] Further preferably, the titanium alloy contact and the LCP insulating layer have the same thickness, and the thickness is both.mm-.mm.

[0012] Further preferably, the nickel-based alloy shielding layer and the alumina ceramic housing have the same thickness, and the thickness is both.mm-.mm.

[0013] Due to the adoption of the above technical solutions in the embodiments of the present utility model, it has the following advantages:

[0014] First, the present utility model provides a first functional layer including a titanium alloy contact and an LCP insulating layer. Among them, the titanium alloy contact can still maintain good mechanical properties and electrical properties in a high-temperature environment, ensuring that the contact part can still maintain stable electrical contact in a high-frequency vibration and impact environment, reducing the risk of performance degradation caused by poor contact. The LCP insulating layer has excellent high-temperature resistance performance, can effectively isolate external heat, prevent damage to internal electrical components caused by high temperature, and its low dielectric constant and dielectric loss also help to reduce signal attenuation and interference, improving the performance of the RF connector body.

[0015] Second, the present utility model provides a second functional layer including a nickel-based alloy shielding layer and an alumina ceramic housing. Among them, the nickel-based alloy shielding layer has good high-temperature resistance and oxidation resistance, can effectively reflect and absorb external heat, reduce the temperature inside the RF connector body, and its excellent oxidation resistance can also ensure that the shielding layer can still maintain stable performance in a high-temperature environment, providing good electromagnetic shielding for the RF connector body. The alumina ceramic housing can provide a strong and high-temperature-resistant protective shell for the RF connector body, ensuring that the RF connector body can still maintain stable mechanical properties and electrical properties in a high-temperature environment. In addition, its excellent electrical insulation performance can effectively prevent safety hazards such as electrical short circuits and electric leakage.

[0016] Third, by providing a tungsten copper alloy inner conductor in the present utility model, it can be ensured that in an extremely high-temperature environment, the electrical transmission channel inside the RF connector body can still remain unobstructed, reducing signal attenuation and distortion caused by high temperature.
