Description

Technical Field

[0001] This application relates to the field of electronic components, and in particular to a high-voltage radio frequency connector. Background Technology

[0002] High-voltage RF connectors, as key components for transmitting radio frequency signals, are widely used in high-precision fields such as communications and semiconductor manufacturing. Among them, high-voltage RF connectors play a crucial role in equipment such as semiconductor manufacturing, as they need to withstand extremely high operating voltages.

[0003] In existing technologies, to improve the high-voltage withstand performance of high-voltage RF connectors and prevent breakdown or arcing under high voltage, the common design approach is to increase the physical distance between the internal conductor and the shell, i.e., to increase the creepage distance. This increases the voltage withstand rating by extending the path of potential current leakage along the insulator surface. However, this design approach has an inherent technical contradiction: to achieve higher voltage withstand capability, a longer creepage distance must be designed, which inevitably leads to a significant increase in the overall size of the connector (especially its axial and radial dimensions).

[0004] As high-end manufacturing equipment, such as semiconductors, evolves towards integration, precision, and miniaturization, the dimensional requirements for internal components are becoming increasingly stringent. Existing large-size high-voltage RF connectors struggle to meet the compact spatial layout requirements of equipment, occupying valuable internal space and increasing overall weight and cost. Therefore, how to achieve miniaturization of high-voltage RF connectors without sacrificing high-voltage withstand capability, and resolving the contradiction between high voltage withstand capability and small size, has become a pressing technical problem in this field. Utility Model Content

[0005] To address the problems in the prior art, this application provides a high-voltage radio frequency connector.

[0006] This application provides a high-voltage radio frequency connector, including a connector body, a seal, a cable, an insulator, a center pin, and insulating adhesive. The connector body has an internal potting space and a potting port that communicates with the potting space, which is used to contain insulating adhesive. The seal is detachably disposed at the potting port to seal it. The cable is connected to the connector body and extends into it, with at least a portion of the cable surrounded by the potting space. The insulator is disposed inside the connector body and, together with the connector body, the seal, and the cable, surrounds the potting space. The center pin extends into the insulator and is connected to the cable, with the center pin spaced apart from the potting space along the axial direction of the high-voltage radio frequency connector. Insulating adhesive fills the potting space and surrounds the cable, with the adhesive located at the connection point between the cable and the center pin on the side away from the center pin along the axial direction of the high-voltage radio frequency connector.

[0007] Understandably, this application utilizes a potting space within the connector body and injects insulating adhesive through a potting port, allowing the high-dielectric-strength insulating adhesive to fully fill the gaps around the cable. After curing, this insulating adhesive forms a dense insulating layer, significantly improving the insulation performance of the cable entry area, effectively isolating potential discharge paths and suppressing arcing. This avoids the design approach of relying on increasing physical creepage distance to improve withstand voltage levels, and solves the technical problem in existing technologies where achieving high withstand voltage necessitates increasing connector size, resulting in bulky products that cannot meet the space requirements of miniaturized devices. It achieves ultra-high withstand voltage requirements (e.g., 45KV) while significantly reducing the overall connector size (e.g., the length can be shortened to half of a conventional design), giving the product both excellent miniaturization and ultra-high withstand voltage performance.

[0008] In one embodiment, the connector body includes a connecting portion, an opening portion, and a lead portion. The opening portion is located between the connecting portion and the lead portion. The opening portion is connected to the connecting portion and the lead portion on both sides along the axial direction of the high-voltage radio frequency connector, respectively. The potting port is opened in the opening portion, and the potting space is opened at least in the connecting portion. The insulator and the center pin are both located in the connecting portion. The cable extends from the lead portion to the connecting portion, and the center pin is connected to the side of the cable away from the lead portion.

[0009] Understandably, the glue-filling port is located in a dedicated opening, separating the glue-filling operation from the core electrical connection area (connection section). This facilitates processes such as glue filling, venting, and sealing, improving the convenience and reliability of production and assembly. Simultaneously, this partitioned design makes the functions of each part more independent, which is beneficial for optimizing design and manufacturing, ensuring the stability and consistency of product performance.

[0010] In one embodiment, the potting space extends from the potting port toward the interior of the connection portion, and the potting space is formed by at least a portion of the insulator and the connector body protruding along the radial direction of the high-voltage radio frequency connector.

[0011] Understandably, designing the potting space as a radially convex structure increases the filling volume of the insulating adhesive in that specific area, effectively increasing the radial thickness of the insulating layer. This specifically enhances the radial insulation capability between the connector body and the internal conductor, more effectively preventing arcing along the radial path, thereby further improving the overall high-voltage resistance and structural reliability of the connector.

[0012] In one embodiment, the insulating adhesive includes an axial portion and a radial portion. The axial portion is disposed around the outside of the cable along the axial direction of the high-voltage radio frequency connector, and the radial portion is connected to the axial portion and extends outward of the connector body along the radial direction of the high-voltage radio frequency connector.

[0013] Understandably, designing the insulating adhesive with both axial and radial portions creates a three-dimensional, all-around insulating protective layer. The axial portion provides longitudinal insulation along the cable, while the radial portion provides lateral insulation. Together, they form a more robust insulating barrier, effectively blocking any potential discharge paths along the axial and radial directions, resulting in more thorough and reliable insulation.

[0014] In one embodiment, the radial portion is located between the insulator and the connector body.

[0015] Understandably, placing the radial portion of the insulating adhesive between the insulator and the connector body directly fills the gap between the internal live components (isolated by the insulator) and the outer shell (connector body). This blocks the shortest and most likely path to electrical breakdown, improves the insulation strength between the insulator and the connector body, and enhances the overall voltage withstand level of the connector.

[0016] In one embodiment, the opening portion has two glue inlets, which are located on opposite sides of the opening portion.

[0017] Understandably, having two opposing dispensing ports allows for the injection of insulating adhesive through one port and the use of the other as an vent during the dispensing process. This ensures that air within the dispensing space is fully expelled, preventing defects in the insulation layer caused by residual air bubbles (the insulation strength at air bubbles is much lower than that of the adhesive itself). This guarantees the density and uniformity of the insulating adhesive filling, significantly improving dispensing quality and the insulation reliability of the product.

[0018] In one embodiment, the high-voltage radio frequency connector further includes a sealing ring, which is sleeved on the outside of the opening and cooperates with the opening to clamp the seal.

[0019] Understandably, using a sealing ring to clamp and fix the seal from the outside allows the sealing ring to apply uniform pressure to the seal, ensuring a long-lasting and stable sealing effect at the glue inlet. This effectively prevents leakage of the insulating adhesive before curing or intrusion of external moisture and contaminants after curing, thus enhancing the long-term stability and environmental tolerance of the product.

[0020] In one embodiment, the seal is fixed in the injection port by an interference fit.

[0021] Understandably, using an interference fit to fix the seal is a simple, low-cost, and extremely reliable mechanical fixing method. It eliminates the need for additional fasteners (such as threads, clips, etc.), simplifies the connector structure and assembly process, reduces manufacturing costs, and provides sufficient holding force and sealing performance to ensure effective sealing of the potting port.

[0022] In one embodiment, the end of the center pin away from the cable is located outside the insulator, and a contour groove is provided on the side of the insulator away from the potting space, the contour groove surrounding the center pin; the high-voltage radio frequency connector also includes an insulating ring, the insulating ring being located in the contour groove and surrounding the center pin.

[0023] Understandably, a contoured groove and an insulating ring are added to the other side of the insulator (the side away from the potting area) to create a second layer of insulation reinforcement. The insulating ring filled in the groove provides material insulation, effectively improving the high voltage resistance of the center pin protrusion without significantly increasing the overall size of the connector.

[0024] In one embodiment, the insulating ring and the insulating adhesive are spaced apart along the axial direction of the high-voltage radio frequency connector and are located on both sides of the insulator, respectively.

[0025] Understandably, during connector installation, the threaded tightening compresses the insulating ring, which in turn isolates the arc between the center pin and the connector body. The insulating adhesive isolates the arc at the tail of the high-voltage RF connector, while the insulating ring isolates the arc on the mounting surface. The combined effect of the insulating ring and insulating adhesive ensures that the high-voltage RF connector has good voltage withstand capability along its entire axial length, improving its overall reliability and safety.

[0032] The following is in conjunction with the appendix Figures 1 to 5 This application will be described in further detail below.

[0033] The technical solutions in the embodiments of this application will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of this application, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of this application without creative effort are also within the protection scope of this application.

[0034] This application provides a high-voltage radio frequency connector, including a connector body 11, a seal 12, a cable 13, an insulator 14, a center pin 15, and insulating adhesive 16. The connector body 11 has an internal potting space 1110 and a potting port 1120 on its surface, communicating with the potting space 1110. The potting space 1110 is used to contain the insulating adhesive 16. The seal 12 is detachably disposed at the potting port 1120 to seal it. The cable 13 is connected to the connector body 11 and extends into the connector body 11, with at least a portion of the cable 13 surrounded by the potting space 1110. The insulator 14 is partially disposed on the connector body. The body 11 is inside the connector body 11, and together with the connector body 11, the seal 12 and the cable 13, it forms a potting space 1110; the center pin 15 extends into the insulator 14 and is connected to the cable 13. The center pin 15 is spaced apart from the potting space 1110 along the axial direction of the high voltage radio frequency connector; the insulating glue 16 is filled in the potting space 1110 and surrounds the cable 13. The insulating glue 16 is located at the connection between the cable 13 and the center pin 15 on the side away from the center pin 15 along the axial direction of the high voltage radio frequency connector.

[0035] In this embodiment, the connector body 11 serves as the outer shell of the entire high-voltage RF connector, and an insulator 14 is assembled inside it. The center pin 15 serves as a signal conductor, with one end reliably connected to the inner conductor of the cable 13 introduced from the tail of the connector body 11, and the other end extending out as the signal interface of the high-voltage RF connector. The insulator 14 electrically isolates the center pin 15 from the connector body 11. A potting space 1110 of a specific shape is pre-designed between the connector body 11, the insulator 14, and the cable 13. Liquid insulating adhesive 16 (specifically, vacuum adhesive, model Dow Corning DC-184) is injected into the potting space 1110 through the potting port 1120 on the connector body 11, forming an insulating protective layer around the lead-in end of the cable 13. The potting port 1120 is sealed with a sealant 12 to protect the internal insulation structure. The insulating adhesive 16 is located after the connection between the cable 13 and the center pin 15 (i.e., on the side away from the protruding end of the center pin 15 along the axial direction) to enhance the high voltage resistance of the cable 13 entry area. The signal transmission part of the center pin 15 is spaced apart from the adhesive area in the axial direction, ensuring that the transmission quality of the radio frequency signal is not affected.

[0036] Understandably, this application provides a potting space 1110 inside the connector body 11 and injects insulating adhesive 16 through the potting port 1120, allowing the high dielectric strength insulating adhesive 16 to fully fill the gaps around the cable 13. After curing, the insulating adhesive 16 forms a dense insulating layer, significantly improving the insulation performance of the cable 13 entry area, effectively isolating potential discharge paths and suppressing arc generation. This avoids the design approach of relying on increasing the physical creepage distance to improve the withstand voltage level, solving the technical problem in the prior art where increasing the connector size to achieve high withstand voltage results in a bulky product that cannot meet the space requirements of miniaturized devices. It can achieve ultra-high withstand voltage requirements (e.g., 45KV) while significantly reducing the overall size of the connector (e.g., the length can be shortened to half of the conventional design, more specifically from 235mm to 108mm), giving the product both excellent performance in miniaturization and ultra-high withstand voltage. Embodiments of this application provide a high-voltage radio frequency connector, particularly a high-voltage radio frequency connector.

[0037] In one embodiment, the connector body 11 includes a connecting portion 111, an opening portion 112, and a lead portion 113. The opening portion 112 is located between the connecting portion 111 and the lead portion 113. The opening portion 112 is connected to the connecting portion 111 and the lead portion 113 on both sides along the axial direction of the high-voltage radio frequency connector, respectively. A potting port 1120 is opened in the opening portion 112, and a potting space 1110 is opened at least in the connecting portion 111. An insulator 14 and a center pin 15 are both provided in the connecting portion 111. A cable 13 extends from the lead portion 113 to the connecting portion 111, and the center pin 15 is connected to the side of the cable 13 away from the lead portion 113.

[0038] In this embodiment, the lead portion 113 is located at the tail end of the high-voltage RF connector, serving as a channel and fixing area for the cable 13. The connecting portion 111 is located at the front end of the high-voltage RF connector, and is the area for achieving electrical and mechanical connection with external devices or another connector. The connecting portion 111 internally accommodates the insulator 14 and the center pin 15. The opening portion 112 serves as a transition area connecting the connecting portion 111 and the lead portion 113, and is used to open the potting port 1120. Its radial dimension can be designed to be slightly smaller than that of the connecting portion 111 and the lead portion 113, forming a groove to facilitate subsequent sealing operations.

[0039] Understandably, the glue-filling port 1120 is located in a dedicated opening 112, separating the glue-filling operation from the core electrical connection area (connection part 111). This facilitates processes such as glue filling, venting, and sealing, improving the convenience and reliability of production and assembly. Simultaneously, this partitioned design makes the functions of each part more independent, which is beneficial for optimizing design and manufacturing, ensuring the stability and consistency of product performance.

[0040] In one embodiment, the potting space 1110 extends from the potting port 1120 toward the interior of the connector 111, and the potting space 1110 is provided with at least a portion of the insulator 14 and the connector body 11 protruding along the radial direction of the high voltage radio frequency connector.

[0041] In this embodiment, the overall shape of the potting space 1110 is roughly "+" shaped. The protruding part can form a thicker insulating layer in the radial direction, that is, between the inner cable 13 / insulator 14 and the outer connector body 11, thereby specifically improving the voltage withstand capability of the high voltage RF connector.

[0042] Understandably, designing the potting space 1110 as a radially convex structure increases the filling volume of the insulating adhesive 16 in that specific area, thus increasing the radial insulation layer thickness of the insulating adhesive 16. This specifically strengthens the radial insulation capability between the connector body 11 and the internal conductor, more effectively preventing arcing along the radial path, thereby further enhancing the overall high-voltage resistance and structural reliability of the connector.

[0043] In one embodiment, the insulating adhesive 16 includes an axial portion 161 and a radial portion 162. The axial portion 161 is disposed around the outside of the cable 13 along the axial direction of the high-voltage radio frequency connector, and the radial portion 162 is connected to the axial portion 161 and extends outward of the connector body 11 along the radial direction of the high-voltage radio frequency connector.

[0044] In this embodiment, the shape of the cured insulating adhesive 16 corresponds to the shape of the potting space 1110, naturally forming an interconnected axial portion 161 and radial portion 162, presenting an overall shape resembling a cross-section with a near-T-shape on one side. The axial portion 161 tightly wraps around the outer sheath of the cable 13, filling the gap between the cable 13 and the rear end of the insulator 14, preventing surface discharge along the surface of the cable 13. The radial portion 162 fills the radially protruding space, forming the main radial insulation barrier.

[0045] Understandably, configuring the insulating adhesive 16 with an axial portion 161 and a radial portion 162 creates a three-dimensional, all-around insulating protective layer. The axial portion 161 provides longitudinal insulation along the cable 13, while the radial portion 162 provides lateral insulation. Together, they form a more robust insulating barrier, completely blocking any discharge channels that may occur along the axial and radial directions, resulting in a more thorough and reliable insulation effect.

[0046] In one embodiment, the radial portion 162 is located between the insulator 14 and the connector body 11.

[0047] In this embodiment, the radial portion 162 of the insulating adhesive 16 fills the gap between the outer surface of the rear section of the insulator 14 and the inner wall of the connection portion 111 of the connector body 11. Filling this gap with high dielectric strength insulating adhesive 16 directly increases the breakdown voltage of this critical path.

[0048] Understandably, by placing the radial portion 162 of the insulating adhesive 16 between the insulator 14 and the connector body 11, the gap between the internal live parts (isolated by the insulator 14) and the outer shell (connector body 11) is directly filled. This blocks the shortest and most easily electrical breakdown path, improves the insulation strength between the insulator 14 and the connector body 11, and enhances the overall voltage withstand level of the connector.

[0049] In one embodiment, the opening portion 112 has two glue inlets 1120, which are located on opposite sides of the opening portion 112.

[0050] In this embodiment, to ensure the quality of the adhesive dispensing, two dispensing ports 1120 can be opened on the opening portion 112 at circumferentially opposite positions (e.g., 180° apart). In actual production operations, one dispensing port 1120 can be used as an injection port to connect to the dispensing equipment; the other can be used as an vent. When the liquid insulating adhesive 16 is injected from the injection port, the air in the dispensing space 1110 is pushed by the adhesive and discharged from the vent. When the operator can observe a continuous flow of adhesive from the vent, it can be determined that the internal air has been completely expelled, thereby ensuring that the cured insulating adhesive 16 is free of bubbles and defects.

[0051] Understandably, setting two opposing dispensing ports 1120 allows for the injection of insulating adhesive 16 through one port during the dispensing operation, while the other serves as an vent. This ensures that air within the dispensing space 1110 is fully expelled, preventing defects in the insulation layer caused by residual air bubbles (the insulation strength at air bubbles is much lower than that of the adhesive). This guarantees the density and uniformity of the insulating adhesive 16 filling, significantly improving dispensing quality and the insulation reliability of the product.

[0052] In one embodiment, the high-voltage radio frequency connector further includes a sealing ring 17, which is sleeved on the outside of the opening portion 112, and the sealing ring 17 cooperates with the opening portion 112 to clamp the sealing member 12.

[0053] In this embodiment, the sealing element 12 can be two semi-circular plugs used to block the glue-filling port 1120. The sealing ring 17 is a complete O-ring, metal retainer, or plastic ring, which is installed in the groove on the outer periphery of the opening 112. After the sealing element 12 is inserted into the glue-filling port 1120, the sealing ring 17 is then put on. The elastic or rigid constraint force of the sealing ring 17 will press the sealing element 12 inward, thereby achieving a firm clamping and sealing of the glue-filling port 1120.

[0054] Understandably, the sealing ring 17 is used to clamp and fix the seal 12 from the outside. The sealing ring 17 can apply uniform pressure to the seal 12, ensuring that the sealing effect of the glue filling port 1120 is long-lasting and stable, effectively preventing the insulation glue 16 from leaking before curing or the intrusion of external moisture and pollutants after curing, thus enhancing the long-term stability and environmental tolerance of the product.

[0055] In one embodiment, the seal 12 is fixed in the glue inlet 1120 by an interference fit.

[0056] In this embodiment, the seal 12 can be designed as a plug slightly larger than the diameter of the glue inlet 1120, and its material has a certain degree of elasticity and insulation. During assembly, the seal 12 is forcibly pressed into the glue inlet 1120 by external force. The seal 12 and the hole wall generate huge radial pressure, forming a tight interference fit, which has a good sealing effect.

[0057] Understandably, using an interference fit to fix the seal 12 is a simple, low-cost, and extremely reliable mechanical fixing method. It eliminates the need for additional fasteners (such as threads, clips, etc.), simplifies the connector's structure and assembly process, reduces manufacturing costs, and provides sufficient holding force and sealing performance to ensure effective sealing of the potting port 1120.

[0058] In one embodiment, the end of the center pin 15 away from the cable 13 is located outside the insulator 14, and the side of the insulator 14 away from the potting space 1110 is provided with a contour groove 141, which surrounds the center pin 15; the high-voltage radio frequency connector also includes an insulating ring 18, which is located in the contour groove 141 and surrounds the center pin 15.

[0059] In this embodiment, an annular groove, or contour groove 141, is machined around the protruding center pin 15 on the front end face of the insulator 14 for connection with external devices, improving the connection effect. An insulating ring 18 is provided at the bottom of the contour groove 141 to isolate electric arcs from the mounting surface. The insulating ring 18 can also be an O-ring.

[0060] Understandably, a contoured groove 141 and an insulating ring 18 are added to the other side of the insulator 14 (the side away from the potting area) to create a second layer of insulation reinforcement. The insulating ring 18, filled in the groove, provides material insulation and effectively improves the high voltage resistance of the protruding end of the center pin 15 without significantly increasing the overall size of the connector.

[0061] In one embodiment, the insulating ring 18 and the insulating adhesive 16 are spaced apart along the axial direction of the high-voltage radio frequency connector and are located on both sides of the insulator 14, respectively.

[0062] In this embodiment, the insulating adhesive 16 is located on the rear side of the insulator 14, which can solve the withstand voltage problem at the cable 13 entry end. The insulating ring 18 is located on the front side of the insulator 14, which can solve the withstand voltage problem at the connector mating surface.

[0063] Understandably, during installation, the threaded locking mechanism of the high-voltage RF connector compresses the insulating ring 18, which in turn isolates the arc between the center pin 15 and the connector body 11. The insulating adhesive 16 isolates the arc at the tail of the high-voltage RF connector, and the insulating ring 18 isolates the arc on the mounting surface. The combined effect of the insulating ring 18 and the insulating adhesive 16 ensures that the high-voltage RF connector has good voltage withstand capability along its entire axial length, improving the overall reliability and safety of the high-voltage RF connector.

[0064] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
