Description

Technical Field

[0001] The invention relates to a dynamic intermodulation stable ultra-flexible radio frequency cable connector and a use method thereof. Background Art

[0002] RF cable connectors, also known as RF coaxial connectors, are connectors used in radio frequency bands and are connected to coaxial cables, microstrip lines or other RF transmission lines to achieve electrical connection, separation or transfer of different types of transmission lines. They are mechatronics products that play a bridging role.

[0003] The conventional hard connection products currently available on the market that are suitable for upper and lower plate-shaped cavities rely on the elastic clamping of the inner conductor slots to generate inner conductor contact signals, and rely on the elastic strength of the slotted parts injection molding, which has insufficient constraint strength and is not resistant to shaking, resulting in poor intermodulation dynamic test results. The ultra-flexible RF radio frequency outer conductor is a spiral pattern, and there is a gap and poor contact due to side wall extrusion, resulting in poor intermodulation dynamic test results. The sealing ring material is a rubber part with insufficient hardness, and the constraint effect is still slight shaking and rotation, resulting in poor intermodulation dynamic test results. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a dynamically intermodulation stable ultra-flexible RF cable connector and a method of using the same. The connector generates an inner conductor contact signal by relying on the elastic clamping of the inner conductor slot itself, and increases the outer layer of the medium to wrap around the outer wall of the connector to play an additional constraint role. The high ductility of the copper outer conductor material is utilized, and the U-shaped wrinkled end face of the cable outer conductor is compressed into a W shape to form a block. A contoured sealing metal extrusion bushing is used, and the contoured sealing extrusion bushing and the connector shell are extruded to fold the outer conductor into a W shape. Rigid extrusion is used to replace conventional soft sealing extrusion to obtain a stable support position. Two rigid support positions are established in the product structure to form a stable lever point. The microwave fluctuations of the cable will not be transmitted to the front inner conductor position. The inner conductor in the product structure is wrapped with an external non-metallic method to ensure the stability of the inner conductor after contact.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a dynamically intermodulation stable ultra-flexible radio frequency cable connector, comprising a connector body and a stable clamping assembly, wherein a connector front shell and a connector rear shell are sleeved on the connector body, and a connector inner conductor is inserted into the connector body, and the connector inner conductor is clamped by the stable clamping assembly to generate a connector inner conductor contact signal.

[0006] As a preferred technical solution of the present invention, the stable clamping assembly includes a slot opened in the connector body, and the slot clamps the conductor in the connector by relying on its own elasticity.

[0007] As a preferred technical solution of the present invention, a cable core is inserted into the inner conductor of the connector.

[0008] As a preferred technical solution of the present invention, the outer side of the connector body is wrapped with an outer layer of medium.

[0009] As a preferred technical solution of the present invention, the connector rear shell is installed on the connector body through a connector rear locking nut, and a gap is preset between the connector rear locking nut and the connector front shell.

[0010] As a preferred technical solution of the present invention, an outer conductor of a cable is clamped in the gap.

[0011] As a preferred technical solution of the present invention, the end surface of the cable outer conductor located in the gap is compressed and folded into a block shape in a W shape.

[0012] As a preferred technical solution of the present invention, a sealed metal extrusion bushing is provided between the outer conductor of the cable and the front housing of the connector.

[0013] A method for using a dynamic intermodulation stable ultra-flexible radio frequency cable connector, the specific steps are as follows: S1. First, a slot is opened in the connector body, and the inner conductor of the connector is inserted into the slot. The inner conductor of the connector is clamped by the elasticity of the slot itself. As the inner conductor of the connector abuts against the inner wall of the slot, the inner conductor of the connector generates a contact signal; S2, inserting the inner core of the cable into the inner conductor of the connector, and wrapping an outer layer of dielectric around the outside of the connector body to constrain the inner conductor of the connector in the connector body; S3, insert the outer conductor of the cable into the connector body, and install the connector front shell and the connector rear shell on the connector body, so that a gap is formed between the connector front shell and the connector rear shell; S4. After the rear housing of the connector is fixed by rotating the locking nut at the rear of the connector, the outer conductor of the cable located in the gap compresses the U-shaped wrinkled end face into a W-shape and folds it into a block through the gap; S5. A sealed metal extrusion bushing is provided between the front housing of the connector and the outer conductor of the cable for stable support.

[0014] Compared with the prior art, the beneficial effects that the present invention can achieve are: relying on the elastic clamping of the inner conductor slot itself to generate an inner conductor contact signal, increasing the outer layer of the medium to wrap around the outer wall of the connector to play an additional restraining role, utilizing the high ductility of the copper outer conductor material, the cable outer conductor compresses the U-shaped wrinkled end face into a W shape to form a block, and adopts a contoured sealing metal extrusion bushing.

Two rigid support positions are established in the product structure to form a stable lever point. The microwave fluctuations of the cable will not be transmitted to the front inner conductor position. The inner conductor in the product structure adopts an external non-metallic wrapping method to ensure the stability of the inner conductor after contact. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention. The experimental methods in the following embodiments, unless otherwise specified, are conventional methods, and the materials, reagents, etc. used in the following embodiments, unless otherwise specified, can be obtained from commercial channels.

[0018] Example: like Figure 1 - Figure 8 As shown, this embodiment proposes a dynamic intermodulation stable ultra-flexible radio frequency cable connector, including a connector body 1 and a stable clamping assembly, the connector body 1 is sleeved with a connector front shell 2 and a connector rear shell 3, a connector inner conductor 4 is inserted into the connector body 1, and the connector inner conductor 4 is clamped by the stable clamping assembly to generate a connector inner conductor 4 contact signal; Relying on the elastic clamping of the inner conductor slot 5 itself, the inner conductor contact signal is generated, and the outer layer medium 7 is added to wrap the outer wall of the connector to play an additional restraining role. Utilizing the high ductility of the copper outer conductor material, the cable outer conductor 10 compresses the U-shaped wrinkled end face into a W shape and folds it into a block. A contoured sealing metal extrusion bushing 11 is adopted. The contoured sealing extrusion bushing and the connector shell are extruded to fold the outer conductor into a W shape. Rigid extrusion is used to replace conventional soft sealing extrusion to obtain a stable supporting position. Two rigid supporting positions are established in the product structure to form a stable lever point. The microwave fluctuations of the cable will not be transmitted to the front inner conductor position. The inner conductor in the product structure adopts an external non-metallic wrapping method.

[0019] Among them, the stable clamping assembly includes a slot 5 opened in the connector body 1, and the slot 5 clamps the connector inner conductor 4 by its own elasticity. The connector inner conductor 4 is plugged with a cable inner core 6. In the prior art, the slot 5 is relied on for injection molding elastic strength, which is insufficient in constraint strength and is not resistant to shaking, resulting in poor intermodulation dynamic test results. The present application relies on the inner conductor slot 5 to clamp itself elastically, generates an inner conductor contact signal, and increases the outer layer medium 7 to wrap the outer wall of the connector, which plays an additional constraint role. The prior art ultra-flexible RF radio frequency outer conductor is a spiral pattern, and the side wall is squeezed to have a gap 9 with poor contact, resulting in poor intermodulation dynamic test results. The outer side of the connector body 1 in the present application is wrapped with an outer layer medium 7. In the present application, the high ductility of the copper outer conductor material is utilized, and the cable outer conductor 10 compresses the U-shaped wrinkled end face into a W shape and folds it into a block. The connector rear shell 3 is installed on the connector body 1 through the connector rear locking nut 8, and a gap 9 is preset between the connector rear locking nut 8 and the connector front shell 2. The gap 9 clamps the outer conductor 10 of the cable, and the end face of the outer conductor 10 of the cable located in the gap 9 is compressed and folded into a block in a W shape. In the prior art, the sealing ring material is a rubber part with insufficient hardness, and the restraining effect is still slight shaking and rotation, resulting in poor intermodulation dynamic test effect. A sealing metal extrusion bushing 11 is arranged between the outer conductor 10 of the cable and the front shell 2 of the connector. A contoured sealing metal extrusion bushing 11 is adopted. The contoured sealing extrusion bushing and the connector shell are extruded to fold the outer conductor in a W shape, and rigid extrusion is used instead of conventional soft sealing extrusion to obtain a stable support position. The dynamic stability fluctuation of conventional products is + / -3dbm; the dynamic stability fluctuation of the structure of the present invention is + / -0.2dbm. To meet the increase in dynamic test conditions, the conventional dynamic intermodulation requirement is to make a circular shaking along 3 times the outer diameter of the cable. The structure of the present invention can achieve more than 20 times the circumferential shaking along the outer diameter of the cable.

[0020] A method for using a dynamic intermodulation stable ultra-flexible radio frequency cable connector, the specific steps are as follows: S1. First, a slot 5 is opened in the connector body 1, and the connector inner conductor 4 is inserted into the slot 5. The connector inner conductor 4 is clamped by the elasticity of the slot 5. As the connector inner conductor 4 abuts against the inner wall of the slot 5, the connector inner conductor 4 generates a contact signal; S2, inserting the cable inner core 6 into the connector inner conductor 4, and wrapping an outer layer of the connector body 1 with an outer dielectric 7 to constrain the connector inner conductor 4 in the connector body 1; S3, insert the cable outer conductor 10 into the connector body 1, and install the connector front shell 2 and the connector rear shell 3 on the connector body 1, so that a gap 9 is formed between the connector front shell 2 and the connector rear shell 3; S4, after the connector rear housing 3 is fixed by rotating the connector rear locking nut 8, the cable outer conductor 10 located in the gap 9 passes through the gap 9 to compress the U-shaped wrinkled end surface into a W shape and fold into a block; S5. A sealing metal extrusion bushing 11 is provided between the front housing of the connector and the outer conductor 10 of the cable for stable support.
