Description

Technical Field

[0001] This utility model relates to the field of radio frequency connector technology, specifically a high-temperature resistant radio frequency connector. Background Technology

[0002] RF connectors provide signal transmission with low insertion loss, low noise, and low distortion, thus ensuring signal integrity. This is crucial for high-quality wireless communication systems, radar systems, and satellite communication systems, as they require accurate and rapid signal transmission and processing.

[0003] Existing RF connectors need to transmit high-frequency signal data, which causes them to generate high temperatures during operation. RF connectors that are exposed to high temperatures for a long time may be damaged.

[0004] To address existing defects, a high-temperature resistant radio frequency connector with publication number CN217281301U is disclosed. It uses a riveting process to form a groove on the inner wall of the threaded sleeve. The groove holds the connector shell and insulator inside the threaded sleeve. When the inner conductor of the radio frequency connector is soldered, the insulator will not be affected by high temperature and will not expand or shift, thus improving the electrical performance of the radio frequency connector.

[0005] In actual use, although the above-mentioned device achieves high temperature resistance through insulators, the range of high temperature resistance of the insulators is relatively limited, which may lead to the failure of the insulators at high temperatures, resulting in poor high temperature resistance.

[0006] Therefore, we proposed a high-temperature resistant RF connector that can effectively solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a high-temperature resistant radio frequency connector to solve the problem mentioned in the background art that the current market insulators have a limited range of high-temperature resistance, which may lead to insulator failure at high temperatures and thus poor high-temperature resistance.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant radio frequency connector, comprising a radio frequency connector body, wherein a socket is fixed inside the radio frequency connector body;

[0009] Also includes:

[0010] The inner wall of the RF connector body is fitted with a ceramic body, which is located on the outside of the socket, and the ceramic body is set at the same height as the inner wall of the RF connector body.

[0016] Preferably, the slider has a protrusion slidably connected inside, and the outer end of the protrusion is semi-circular. The outer end of the protrusion extends into the interior of the groove to form a locking mechanism. The groove is opened inside the RF connector body, and the inner end of the protrusion is connected to a spring, and the inner end of the spring is connected to the interior of the slider.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1: This utility model solves the problem that existing insulators have a limited range of high-temperature resistance, which may lead to insulator failure at high temperatures and thus poor high-temperature resistance. The ceramic body 3 can improve the high-temperature resistance performance. The following is disclosed:

[0032] The RF connector body 1 has a socket 2 fixed inside; it also includes: a ceramic body 3 attached to the inner wall of the RF connector body 1, the ceramic body 3 being located outside the socket 2, and the ceramic body 3 being set at the same height as the inner wall of the RF connector body 1; the ceramic body 3 contains a metal layer 301 inside, and the metal layer 301 is coated on the ceramic body 3 by a molybdenum-manganese metallization process; a nickel layer 302 attached to the inner wall of the metal layer 301, and the nickel layer 302 is attached to the metal layer 301 by a palladium-activated nickel plating process; an insulating layer 303 is provided inside the nickel layer 302, and the insulating layer 303 is made of polytetrafluoroethylene material and is located inside the ceramic body 3; an anti-corrosion layer 304 is provided inside the insulating layer 303, and the anti-corrosion layer 304 is made of a ternary alloy material and is located inside the ceramic body 3;

[0033] refer to Figure 1 and Figure 2 When using the RF connector body 1, the socket 2 on the RF connector body 1 will generate high temperature. The ceramic body 3 can then isolate the high temperature, thereby preventing the high temperature from affecting the use of the RF connector body 1, thus giving the RF connector body 1 high temperature resistance. The metal layer 301 can improve the heat resistance, and the nickel layer 302 can improve the high temperature resistance and corrosion resistance of the ceramic body 3. The insulating layer 303 can isolate the potential difference when the RF connector body 1 is used, thereby preventing current leakage or short circuit. The insulating layer 303 can also improve the heat resistance, and the anti-corrosion layer 304 can improve the corrosion resistance of the ceramic body 3, thereby improving the service life of the ceramic body 3.

[0034] Example 2: This utility model solves the problem in Example 1 where the ceramic body 3 needs to be replaced with the RF connector body 1 after damage, thus increasing the cost of use. By moving the slider 4, the ceramic body 3 can be replaced individually, thereby reducing the cost of use. The following is disclosed:

[0035] A slider 4 is fixed to the outer end of the ceramic body 3, and the outer end of the slider 4 extends into the interior of the slide groove 5 to form a locking mechanism. The slide groove 5 is opened inside the RF connector body 1.

[0036] refer to Figure 1 , Figures 3 to 6When the ceramic body 3 needs to be replaced, the ceramic body 3 is rotated, causing the slider 4 to slide inside the slide groove 5. After the ceramic body 3 is rotated to the position, the slider 4 will disengage from the slide groove 5, and then the ceramic body 3 will be pulled to detach from the inside of the RF connector body 1. Then, a new ceramic body 3 can be taken out. By reversing the above operation, the ceramic body 3 can be installed inside the RF connector body 1, thereby avoiding damage to the ceramic body 3 and affecting its high temperature resistance performance. It also allows for quick disassembly and assembly. By replacing the ceramic body 3 separately, the cost of use is reduced.

[0037] Example 3: This utility model solves the problem of unstable installation of the ceramic body 3 in Example 2. By engaging the protrusion 6, the stability of the ceramic body 3 installed in the RF connector body 1 can be improved. The following is disclosed:

[0038] The slider 4 has a sliding connection to a protrusion 6, and the outer end of the protrusion 6 is semi-circular. The outer end of the protrusion 6 extends into the interior of the groove 7 to form a locking mechanism. The groove 7 is opened inside the RF connector body 1. The inner end of the protrusion 6 is connected to a spring 8, and the inner end of the spring 8 is connected to the interior of the slider 4.

[0039] refer to Figure 1 , Figures 3 to 6 The movement of slider 4 can drive the protrusion 6 to move, which in turn causes the protrusion 6 to be squeezed between itself and the groove 7. This squeezes the protrusion 6 into the slider 4, causing it to disengage from the groove 7. The movement of the protrusion 6 also compresses the spring 8. During installation, after slider 4 and groove 5 are engaged, the force of spring 8 pushes the protrusion 6 into the groove 7 to form a lock, thereby improving the stability of the ceramic body 3 after installation.

[0040] Working principle: When using this high-temperature resistant RF connector, firstly, refer to... Figure 1 and Figure 2 When using the RF connector body 1, the socket 2 on the RF connector body 1 will generate high temperature. The ceramic body 3 can isolate the high temperature, and the metal layer 301 can improve the heat resistance. The nickel layer 302 can improve the high temperature resistance and corrosion resistance of the ceramic body 3. The insulating layer 303 can isolate the potential difference when the RF connector body 1 is used, and the insulating layer 303 can also improve the heat resistance. The anti-corrosion layer 304 can improve the corrosion resistance of the ceramic body 3, thereby improving the service life of the ceramic body 3.

[0041] refer to Figure 1 , Figures 3 to 6When the ceramic body 3 needs to be replaced, the ceramic body 3 is rotated, causing the slider 4 to slide inside the groove 5. After the ceramic body 3 is rotated to the position, the slider 4 will disengage from the groove 5, and then the ceramic body 3 can be pulled to remove the new ceramic body 3. By reversing the above operation, the ceramic body 3 can be prevented from being damaged and thus affecting its high temperature resistance performance. It also allows for quick disassembly and assembly. By replacing the ceramic body 3 separately, the cost of use is reduced.

[0042] refer to Figure 1 , Figures 3 to 6 The movement of slider 4 can drive the protrusion 6 to move, which in turn causes the protrusion 6 to be squeezed between itself and the groove 7, and then the protrusion 6 will disengage from the groove 7. During installation, after slider 4 and groove 5 are engaged, the force of spring 8 pushes the protrusion 6 into the groove 7 to form a lock, thereby improving the stability of ceramic body 3 after installation.
