Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a low-cost 50G millimeter wave cable assembly. Background Technology

[0002] To meet the urgent need for low-cost and miniaturized high-frequency interconnect components in applications such as 5G communication and millimeter-wave radar, this study aims to design a low-cost cable assembly suitable for the 50G millimeter-wave band. Traditional connectors of the same type suffer from problems such as a large number of parts, complex structure, large length, and high material cost, which limit their widespread application and economy in compact spaces. Therefore, it is necessary to design a low-cost cable assembly for 50G millimeter-wave bands. Existing cable assemblies are susceptible to erosion from rain and dust in harsh environments when connected, so there is a need to design a low-cost 50G millimeter wave cable assembly. Utility Model Content

[0003] The purpose of this invention is to provide a low-cost 50G millimeter wave cable assembly to address the shortcomings of existing cable assemblies where the connecting components at both ends are susceptible to erosion by rainwater and dust in harsh environments.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a 50G millimeter wave low-cost cable assembly, including an HF330 cable; The outer wall of the HF330 cable is fixed with a protective structure. Both ends of the HF330 cable are fixed with heat shrink tubing with adhesive sealant. Both ends of the HF330 cable are fixed with pins. Insulators are fixed on the outer wall of the pins. A shell is fixed on the outside of the insulators.

[0005] A screw sleeve is fixed to the outer side of the housing, and a retaining ring is fixed to the inner wall of the screw sleeve near the end of the HF330 cable. A sealing structure is provided on the outer wall of one end of the housing. The sealing structure includes a connecting groove provided on the outer wall of the housing, a connecting gasket provided inside the connecting groove, and a sealing flat gasket fixed on the outer wall of the connecting gasket.

[0006] Furthermore, the protective structure includes an adhesive layer, a shielding layer, and an abrasion-resistant layer. The adhesive layer is fixed to the outer wall of the HF330 cable, the shielding layer is fixed to the outer wall of the adhesive layer, and the abrasion-resistant layer is fixed to the outer wall of the shielding layer.

[0007] Furthermore, the shielding layer is made of self-adhesive aluminum foil, and the wear-resistant layer is made of nylon.

[0008] Furthermore, the outer wall of the retaining ring and the inner wall of the threaded sleeve abut against each other.

[0009] Furthermore, both the outer shell and the pin are made of brass, and the central axis of the pin is collinear with the central axis of the HF330 cable.

[0010] Furthermore, the insulator is made of PTFE material.

[0011] Furthermore, the connecting pad and the housing are connected by an interference fit through a connecting groove.

[0012] The present invention provides a low-cost 50G millimeter wave cable assembly, the advantages of which are: By incorporating a sealing structure located at the end of the housing, the core function of this structure is to achieve environmental sealing at the connector interface. This effectively prevents contaminants such as dust and moisture from entering the connector, avoiding corrosion or degradation of insulation performance of precision contacts such as pins. By maintaining a clean and dry internal environment for the connector, it ensures that the millimeter-wave connection point maintains stable electrical characteristics under harsh operating conditions, greatly improving the long-term reliability and environmental adaptability of the component. This device facilitates sealing of the connectors and enhances the safety of the 50G millimeter-wave low-cost cable assembly during use. By incorporating a protective structure, the internal structure of the HF330 cable is protected from damage during installation and use, ensuring the long-term stability of 50G millimeter-wave signal transmission. The outermost abrasion-resistant layer effectively resists physical damage such as friction and scratches, extending the cable's service life. The middle shielding layer provides crucial electromagnetic shielding performance for the HF330 cable, preventing external electromagnetic interference from affecting high-frequency signals and suppressing internal signal radiation. The inner adhesive layer ensures a tight bond between the shielding layer and the cable body, preventing interlayer loosening and maintaining structural integrity and electrical performance consistency. This design enables the device to easily protect the HF330 cable, improving the durability of this low-cost 50G millimeter-wave cable assembly during use. Attached Figure Description

Detailed Implementation

[0015] 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.

[0016] Please see Figures 1-5 The present invention provides a low-cost 50G millimeter wave cable assembly, including an HF330 cable 1.

[0017] Reference Figures 1-5 A protective structure 2 is fixed to the outer wall of the HF330 cable 1. The protective structure 2 includes an adhesive layer 21, a shielding layer 22, and a wear-resistant layer 23. The adhesive layer 21 is fixed to the outer wall of the HF330 cable 1. The shielding layer 22 is fixed to the outer wall of the adhesive layer 21. The wear-resistant layer 23 is fixed to the outer wall of the shielding layer 22. The shielding layer 22 is made of self-adhesive aluminum foil. The wear-resistant layer 23 is made of nylon. Heat shrink tubing 3 with adhesive seal is fixed to the outer wall of both ends of the HF330 cable 1. Pins 7 are fixed to both ends of the HF330 cable 1. Insulators 8 are fixed to the outer wall of the pins 7. A shell 6 is fixed to the outside of the insulators 8. Both the shell 6 and the pins 7 are made of brass. The central axis of the pins 7 is collinear with the central axis of the HF330 cable 1. The insulators 8 are made of PTFE.

[0018] The adhesive layer 21 serves as the base, ensuring reliable bonding between the protective layer and the HF330 cable 1. The shielding layer 22 is a self-adhesive aluminum foil, which utilizes the properties of metal as a good conductor to form a continuous electromagnetic barrier. When external electromagnetic waves arrive, an induced current is generated on the surface of the aluminum foil. The reverse electromagnetic field generated by this current cancels out most of the interfering electromagnetic waves, thereby achieving the shielding purpose. The wear-resistant layer 23 is a nylon layer, which serves as the outermost sheath. Utilizing the high strength and wear resistance of nylon material, it bears the main mechanical wear and environmental impact.

[0019] Reference Figures 2-5A screw sleeve 5 is fixed to the outer side of the outer casing 6. A retaining ring 4 is fixed to the inner wall of the screw sleeve 5 near the end of the HF330 cable 1. The outer wall of the retaining ring 4 and the inner wall of the screw sleeve 5 abut against each other. A sealing structure 9 is provided on the outer wall of one end of the outer casing 6. The sealing structure 9 includes a connecting groove 93 provided on the outer wall of the outer casing 6. A connecting pad 92 is provided inside the connecting groove 93. A sealing flat pad 91 is fixed on the outer wall of the connecting pad 92. The connecting pad 92 and the outer casing 6 are connected by interference fit through the connecting groove 93.

[0020] The sealing gasket 91 is an elastic sealing ring. When the connector is tightened with the corresponding port, the connecting gasket 92 is pressed into the connecting groove 93, fixing the sealing gasket 91 to the outside of the housing 6. The elastic deformation of the sealing gasket 91 fills all possible micro gaps, forming a physical barrier to prevent external water and dust from entering the connector through the thread gap. Its "interference fit" ensures that the sealing gasket is always under pressure, maintaining the sealing effect.

[0021] Although the present invention 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 invention should be included within the protection scope of the present invention.
