Description

Technical Field

[0001] This utility model relates to the field of radio frequency connector technology, and in particular to a wear-resistant connector for radio frequency components. Background Technology

[0002] Connectors for radio frequency (RF) components are devices used to connect the various parts of an RF assembly. They play a crucial role in the transmission of RF signals and the construction of the system, and can firmly connect the various RF components together to form a stable structure to adapt to different working environments and installation requirements.

[0003] There are various types of connectors, each with a different function, such as RF coaxial connectors, RF adapters, RF cable assemblies, and microwave planar connectors. Among them, RF cable assemblies are often integrated connectors consisting of RF cables and connectors at both ends. They can be customized with cables and connectors of different lengths and types according to specific application requirements, facilitating signal transmission in various RF systems. They are commonly used in base stations, radar, satellite communication, and other systems.

[0004] Considering that dust, impurities, and other contaminants accumulate on the surface of the contacts in connectors over long-term use, these contaminants increase contact resistance, leading to problems such as signal attenuation and distortion during transmission. For example, in some high-precision radio frequency communication systems, even a small change in contact resistance can affect signal quality and cause communication errors. Therefore, a wear-resistant connector for radio frequency components is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a wear-resistant connector for radio frequency components, which aims to solve the problem that in the prior art, dust, impurities and other contaminants accumulated on the surface of the connector's contact parts under long-term use will increase the contact resistance, leading to attenuation and distortion of radio frequency signal transmission. In high-precision radio frequency communication systems, even slight changes in contact resistance can reduce signal quality and cause communication errors.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wear-resistant connector for radio frequency components, comprising a connector, an insulating member fixedly connected to the inner surface of the connector, a scraper slidably connected to the front end of the inner surface of the insulating member, a contact member slidably connected through the inner surface of the scraper, the outer surface of the contact member being fixedly connected through the inner surface of the insulating member, an ejector post fixedly connected to the rear end of the outer surface of the scraper, the outer surface of the ejector post being slidably connected through the inner surface of the insulating member, a hinge post hinged to the rear end of the outer surface of the ejector post, and a locking component provided at the front end of the outer surface of the connector;

[0007] The locking assembly includes a compression shell, the inner surface of which is rotatably connected to the outer surface of the insulating component, a limit ring is fixedly connected to the rear end of the inner surface of the compression shell, the outer surface of the limit ring is rotatably connected to the outer surface of the insulating component, and the inner surface of the compression shell is provided with an internal thread.

[0010] As a further description of the above technical solution:

[0011] The rear end of the outer surface of the connector is fixedly connected to an RF wire, and the rear end of the outer surface of the contact is fixedly connected to the front end of the outer surface of the RF wire.

[0012] As a further description of the above technical solution:

[0013] The outer surface of the gasket is elastically connected to the rear end of the outer surface of the connector via a spring.

[0014] As a further description of the above technical solution:

[0016] As a further description of the above technical solution:

[0017] The inner surface of the movable ring is threaded with a bolt, and the outer surface of the bolt is slidably connected to the rear part of the inner surface of the hinge post.

[0031] 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.

[0032] Reference Figures 1-3This utility model provides an embodiment of a wear-resistant connector for radio frequency components, including a connector 1. An insulating member 8 is fixedly connected to the inner surface of the connector 1, providing fixed support for the insulating member 8. A scraper 9 is slidably connected to the front end of the inner surface of the insulating member 8, allowing the scraper 9 to move laterally along the front end of the inner surface of the insulating member 8. A contact member 3 is slidably connected through the inner surface of the scraper 9, enabling the scraper 9 to scrape and clean the surface of the contact member 3 during lateral movement. The outer surface of the contact member 3 is fixedly connected through the inner surface of the insulating member 8, allowing the insulating member 8 to isolate the contact member 3, preventing short circuits between adjacent contact members 3, and providing mechanical support and positioning for the contact member 3. An ejector post 11 is fixedly connected to the rear end of the outer surface of the scraper 9. The ejector post 11 moves laterally, causing the scraper 9 to move laterally as well. The outer surface of the ejector post 11 penetrates and slides through the inner surface of the insulating member 8, allowing the ejector post 11 to move laterally at a specified position along the inner surface of the insulating member 8. A hinge post 5 is hinged to the rear end of the outer surface of the ejector post 11, allowing the hinge post 5 to move laterally as well as the ejector post 11. The outer surface of the hinge post 5 penetrates and slides through the inner surface of the connector 1, allowing the hinge post 5 to move laterally at a specified position along the interior of the connector 1. A locking assembly 2 is provided at the front end of the outer surface of the connector 1, allowing the connector 1 to be connected to the radio frequency assembly via the locking assembly 2.

[0033] Reference Figures 1-3 The locking assembly 2 includes a tightening shell 201. The inner surface of the tightening shell 201 is rotatably connected to the outer surface of the insulating member 8, allowing the tightening shell 201 to rotate along the outer surface of the insulating member 8. A limiting ring 203 is fixedly connected to the rear end of the inner surface of the tightening shell 201, allowing the tightening shell 201 to rotate simultaneously with the limiting ring 203. The outer surface of the limiting ring 203 is rotatably connected to the outer surface of the insulating member 8, allowing the tightening shell 201 to rotate only at a specified position on the insulating member 8 under the restriction of the limiting ring 203. An internal thread 202 is provided on the inner surface of the tightening shell 201, allowing the tightening shell 201 to be threadedly connected to the external threaded connector on the radio frequency assembly, ensuring that the connector 1 is always plugged into the connector.

[0034] Reference Figures 2-4A movable ring 7 is slidably connected to the rear of the outer surface of connector 1, allowing the movable ring 7 to move laterally along the rear of the outer surface of connector 1. The rear of the outer surface of hinge post 5 is inserted into the inner surface of movable ring 7, allowing the rear of hinge post 5 to rest on movable ring 7, keeping hinge post 5 horizontal. A washer 10 is slidably connected through the rear of the outer surface of hinge post 5, allowing washer 10 to move laterally along the outer surface of hinge post 5. The outer surface of washer 10 contacts the front end of the outer surface of movable ring 7, allowing washer 10 to directly contact the notch on movable ring 7, thus providing an elastic support point for one end of spring 6. An RF wire 4 is fixedly connected to the rear end of the outer surface of connector 1, allowing connector 1 to carry... The effect of fixing the moving RF cable 4 to the RF component is that the rear end of the outer surface of the contact 3 is fixedly connected to the front end of the outer surface of the RF cable 4, so that the contact 3 can be plugged into the connector of the RF component to connect the data of the RF cable 4 to the RF component. The outer surface of the pad 10 is elastically connected to the rear end of the outer surface of the connector 1 through the spring 6, so that the pad 10 can always be in contact with the outer surface of the moving ring 7 without the influence of external force. One end of the spring 6 is in contact with the rear end of the outer surface of the connector 1, and the other end of the spring 6 is in contact with the outer surface of the pad 10, so that when the moving ring 7 is stopped, the moving ring 7 can be elastically reset to the rear side of the connector 1 under the elastic force of the spring 6 between the pad 10 and the rear end of the connector 1.

[0035] Reference Figures 2-4 The inner surface of the moving ring 7 is threaded with a bolt 12, allowing the bolt 12 to rotate and move laterally along the inner surface of the moving ring 7. The outer surface of the bolt 12 is threaded and slidably connected to the rear part of the inner surface of the hinge post 5, allowing the rear part of the hinge post 5 to be fixed to the moving ring 7 by the bolt 12. This allows the moving ring 7 to move laterally, driving the hinge post 5 to move laterally as well. The left part of both the compression shell 201 and the connecting piece 1 is hexagonal, making it easier to rotate the compression shell 201 due to its hexagonal shape. The rear part of the outer surface of the connecting piece 1 is fixedly connected with... The rubber ring 13 provides a fixed support for the outer surface of the connector 1. The outer surface of the radio frequency line 4 penetrates and is fixedly connected to the inner surface of the rubber ring 13. This prevents the connector 1 from directly contacting the surface of the radio frequency line 4 under the action of the rubber ring 13, thus preventing the connector 1 from rubbing against the surface of the radio frequency line 4 during long-term use and causing wear. The inner surface of the spring 6 is slidably connected to the outer surface of the hinge post 5, so that when the hinge post 5 is rotated to a specified angle, the spring 6 can be pulled out along the outer surface of the hinge post 5 for replacement.

[0036] Working principle: When the connector 1 is connected to the RF component, the tightening shell 201 in the locking component 2 on the connector 1 has an internal thread 202 on its inner surface, which can be threaded to the external threaded connector on the RF component, thereby driving the connector 1 to connect with the connector on the RF component and ensuring the stability of the connection.

[0037] When it is necessary to clean the surface of the contact 3, the moving ring 7 is pushed, which drives the hinge column 5 to move laterally. The hinge column 5 drives the ejector column 11 to move, and the ejector column 11 drives the scraper 9 to move laterally along the front end of the inner surface of the insulating part 8 to scrape and clean the surface of the contact 3. When the cleaning is completed and the pushing stops, the moving ring 7 will be elastically reset to the rear side of the connector 1 under the action of the spring 6 and through the pad 10 as an elastic support point.

[0038] When it is necessary to replace the spring 6, first unscrew the bolt 12, then flip the hinge post 5 to the specified angle, and then pull out the spring 6 outward along the outer surface of the hinge post 5 for replacement.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
