Description

Technical Field

[0001] This invention specifically relates to a high-frequency connector with an integrated core and its method of use. Background Technology

[0002] Currently, high-frequency connectors, due to their high operating frequency and small product size, have specific requirements for their internal core structure. They need to be small in size, high in strength, and have high dimensional and geometric tolerances. The dielectric and inner conductor are independent entities, and their respective tolerances are superimposed and accumulated on the internal core assembly. For example, if the dielectric tolerance is ±A, the inner conductor tolerance is ±B, and the internal core assembly tolerance is A±B, then merging two half-piece dielectrics and embedding them into the inner conductor, the dielectric is two separate parts spliced ​​together. The presence of a joint seam in the middle will lead to a reduction in strength. Summary of the Invention

[0003] The purpose of this invention is to provide a high-frequency connector with an integrated core and a method of using the same, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a high-frequency connector with an integrated inner core, comprising an inner conductor, a joint assembly for reducing the processing tolerance between the inner conductor and the dielectric is centrally disposed on the outer side of the inner conductor, the joint assembly comprising an injection-molded insert centrally disposed on the outer side of the inner conductor and viewed as circular from the front, protrusions being equidistantly disposed around the outer wall of the injection-molded insert, an annular outer wall insert being disposed on the outer side of the injection-molded insert, an inner ring portion being disposed within the outer wall insert, and insertion holes adapted to the protrusions being equidistantly disposed around the inner wall of the inner ring portion.

[0005] Preferably, the insertion hole is provided with a friction-reducing unit to reduce friction when the protruding post is inserted. The friction-reducing unit includes a strip groove that is vertically downward along the side of the insertion hole near the inner ring. Connecting rods are provided on both sides of the strip groove, and a roller is provided between the two connecting rods to contact the outer wall of the insertion post when it is inserted.

[0006] Preferably, there are multiple strip grooves, and four are evenly spaced around each of the insertion holes.

[0007] Preferably, an inner core is inserted into the inner conductor, and a disassembly and assembly assembly for disassembling the inner core is provided on the outer side of the inner conductor. The disassembly and assembly assembly includes a sleeve installed on the outer side of the inner conductor, and a groove is formed in the sleeve, with the upper surface of the groove communicating with the outer side of the sleeve.

[0008] Preferably, the inner conductor has a cavity, and the disassembly assembly further includes a connecting plate disposed in the cavity, the connecting plate being inclined.

[0009] Preferably, a spring is connected to the side of the connecting plate near the inner conductor, the end of the spring away from the connecting plate is mounted on the inner conductor, and a locking block is provided on the side of the connecting plate away from the spring.

[0010] Preferably, a top block is provided in the groove, and a notch is opened on the upper surface of the inner conductor for the top block to pass through. The top block passes through the notch and abuts against the locking block. A limiting block is provided on the outside of the top block to prevent the top block from falling off. The limiting block is larger than the inner wall diameter of the notch.

[0011] Preferably, a limiting clamp is installed on the rotating rod, the limiting clamp is located between the two support plates, and three limiting clamps are provided. Preferably, a rubber flexible plate is provided on the side of the cavity near the inner conductor, and the connecting plate is disposed on the rubber flexible plate.

[0012] A method of using a high-frequency connector with an integrated core includes the following steps:

[0013] Step A: First, place the inner conductor and the outer wall insert into the injection mold cavity, melt and inject plastic granules between them, and then insert the protrusion into the socket.

[0014] Step B: As the protrusion is inserted into the socket, the outer wall of the protrusion rubs against the roller. As the roller rotates, the protrusion can be inserted into the socket more smoothly. After the protrusion is inserted into the socket, the inner conductor, the outer wall insert, and the injection-molded insert form an integrated inner core.

[0015] Step C: Fit the sleeve onto the outside of the inner conductor and insert the top block into the cavity through the notch. Fix the sleeve, then pinch the inner core and insert it into the inner conductor. As the inner core is inserted, it squeezes the rubber plate, causing the connecting plate to move away from the inner conductor and squeeze the locking block, so that the locking block is inserted into the groove through the notch and the top block is pushed out.

[0016] Step D: When it is finally necessary to disassemble the inner core, press the top block. The notch on the top block will push the locking block out of the groove into the cavity, and the spring will deform. Further pull the locking block out of the notch. At this time, pull the inner core again to pull the inner core out of the inner conductor.

[0017] The technical effects and advantages of this invention are as follows: This invention provides a high-frequency connector with an integrated inner core and its method of use. The inner conductor and outer wall insert are placed in an injection mold cavity, and plastic granules are melted and injected between them to form an injection-molded insert. The inner conductor, outer wall insert, and injection-molded insert together form an integrated inner core. Due to limitations in machining equipment and capabilities, the cumulative dimensions of individual parts cannot be infinitely improved. However, by using injection molding, only the total length and outer diameter of the part need to be controlled; other precision control is achieved solely through mold machining precision. This greatly improves the machining precision and capability for complex inner core shapes. The optimized use of two or more cylindrical protrusions evenly distributed circumferentially effectively provides holding force. The dimensional accuracy of the component is not accumulated from the machining precision of the parts, but is ensured by the mold precision to guarantee consistency. The protrusions of the injection-molded insert, while ensuring the connection between the inner conductor and the outer wall insert, effectively guarantee the axial strength and circumferential torque resistance of the integrated inner core.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0027] To effectively ensure the axial strength and circumferential torque resistance of the integrated inner core, reference Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the device includes an inner conductor 1. A combined assembly for reducing the processing tolerances between the inner conductor 1 and the dielectric is centrally located on the outer side of the inner conductor 1. The combined assembly includes a centrally located, circularly oriented injection-molded insert 6. Protrusions 7 are equidistantly spaced around the outer wall of the injection-molded insert 6. An annular outer wall insert 2 is located on the outer side of the injection-molded insert 6. An inner ring portion 10 is located within the outer wall insert 2. Insertion holes 9, which are adapted to the protrusions 7, are equidistantly spaced around the inner wall of the inner ring portion 10. When the inner core 4 is inserted into the inner conductor 1, it compresses the rubber flexible plate 3, causing the connecting plate 17 to move away from the inner conductor 1, compressing the locking block 16. The locking block 16 is then inserted into the groove 14 through the notch 19, pushing out the top block 8. Finally, when the inner core 4 needs to be disassembled... Press the top block 8, and push the locking block 16 out of the groove 14 into the cavity 15 through the notch 19. The spring 18 deforms and further pulls the locking block 16 out of the notch 19. At this time, pull the inner core 4 again to pull the inner core 4 out of the inner conductor 1. Control the total length and outer diameter of the part. The remaining precision control can be implemented by the mold processing precision. This can greatly improve the processing precision and capability of the complex inner core 4. The optimized use of two or more cylindrical protrusions 7 evenly distributed in the circumferential direction can effectively provide the implementation of holding force. The dimensional accuracy of the component is not accumulated by the part processing precision, but is guaranteed by the mold precision. The protrusions 7 of the injection molded insert 6, while ensuring the connection between the inner conductor 1 and the outer wall insert 2, very effectively ensure the axial strength and circumferential torque resistance of the integrated inner core 4.

[0028] To improve the dimensional accuracy of components, refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7The insertion hole 9 is provided with a friction-reducing unit to reduce friction when the protrusion 7 is inserted. The friction-reducing unit includes a strip groove 12 vertically downwardly opened along the side of the insertion hole 9 near the inner ring 10. Connecting rods 11 are provided on both sides of the strip groove 12. A roller 13 is provided between two connecting rods 11 to contact the outer wall of the insertion post when it is inserted. Multiple strip grooves 12 are provided, and four are equally spaced around each insertion hole 9. An inner core 4 is inserted into the inner conductor 1, and a disassembly and assembly assembly for disassembling the inner core 4 is provided on the outside of the inner conductor 1. The disassembly and assembly assembly includes a sleeve 5 installed on the outside of the inner conductor 1. A groove 14 is opened in the sleeve 5, and the upper surface of the groove 14 is connected to the outside of the sleeve 5. A cavity 15 is opened in the inner conductor 1. The disassembly and assembly assembly also includes a connecting plate 17 disposed in the cavity 15. The connecting plate 17 is inclined. A spring 18 is connected to the side of the connecting plate 17 near the inner conductor 1. The end of the spring 18 away from the connecting plate 17 is installed on the inner conductor 1. A locking block 16 is provided on the side of the connecting plate 17 away from the spring 18. A top block 8 is provided in the groove 14. A notch 19 is opened on the upper surface of the inner conductor 1 for the top block 8 to pass through. The top block 8 passes through the notch 19 and abuts against the locking block 16. A limiting block is provided on the outside of the top block 8 to prevent it from falling off. The limiting block is larger than the inner wall diameter of the notch 19. A limiting clamp is installed on the rotating rod. The limiting clamp is located between the two support plates. There are three limiting clamps. A rubber flexible plate 3 is provided on the side of the cavity 15 near the inner conductor 1. The connecting plate 17 is set on the rubber flexible plate 3. The dimensional tolerance accuracy of the inner conductor 1 and the outer wall insert 2 after forming an assembly is guaranteed. A heating pipe is used inside the mold to reduce the temperature difference between the injection temperature and the cold mold state, and the injection insert 6 is effectively and fully injected. Injection molding uses embedded injection ports on the sidewalls, with TPX, PEI, and PEEK being the preferred materials. To ensure the fit of the injection-molded insert 6, two or more cylindrical protrusions 7 are preferred. The original half-fitting process, from a microscopic perspective, resulted in inconsistencies between each half; minor inconsistencies were manageable, but severe inconsistencies led to eccentricity after half-fitting. Furthermore, this half-fitting installation process had high requirements, resulting in insufficient product consistency. The optimized use of two or more cylindrical protrusions 7, evenly distributed circumferentially, effectively provides holding force. The position of the inner conductor 1 and the dielectric is ensured by the injection mold, eliminating the accumulation of machining tolerances of the inner conductor 1 and dielectric onto the component. Moreover, since the mold is used for manufacturing under the same injection parameters, individual product differences are minimized.

[0029] A method of using a high-frequency connector with an integrated core includes the following steps:

[0030] Step A: First, place the inner conductor 1 and the outer wall insert 2 into the injection mold cavity, melt and inject plastic particles between them, and then insert the protrusion 7 into the socket 9.

[0031] Step B: As the protrusion 7 is inserted into the socket 9, the outer wall of the protrusion 7 rubs against the roller 13. As the roller 13 rotates, the protrusion 7 can be inserted into the socket 9 more smoothly. After the protrusion 7 is inserted into the socket 9, the inner conductor 1, the outer wall insert 2, and the injection molded insert 6 form an integrated inner core 4.

[0032] Step C: Sleeve 5 is fitted onto the outside of inner conductor 1, and top block 8 is inserted into cavity 15 through notch 19 to fix sleeve 5. Then, inner core 4 is squeezed and inserted into inner conductor 1. As inner core 4 is inserted, it squeezes rubber soft plate 3, causing connecting plate 17 to move away from inner conductor 1 and squeeze block 16, so that block 16 is inserted into groove 14 through notch 19 and top block 8 is pushed out.

[0033] Step D, when the inner core 4 needs to be disassembled, press the top block 8, and push the locking block 16 out of the groove 14 into the cavity 15 through the notch 19 and the top block 8. The spring 18 will deform and further pull the locking block 16 out of the notch 19. At this time, pull the inner core 4 again to pull the inner core 4 out of the inner conductor 1.
