Description

Technical Field

[0001] This utility model relates to the field of radio frequency coaxial connector technology, and in particular to a high-frequency induction welding radio frequency coaxial connector. Background Technology

[0002] High-frequency induction welding radio frequency coaxial connectors are connection devices used to realize radio frequency signal transmission. They reliably connect the connector to the cable through high-frequency induction welding technology.

[0003] The existing RF coaxial connector has a complex internal structure, which means that testing the air tightness of the RF coaxial connector requires setting up an additional air intake channel to ensure that both ends can be tested, which is cumbersome.

[0004] The existing patent (publication number: CN213520402U) describes an easy-to-test RF coaxial connector. By using a design with an external vent groove as a ventilation structure, it ensures smooth airflow between the two ends of the outer conductor and automatically adjusts the internal and external air pressure balance of the product. During testing, the air tightness test can be performed from the air inlet end of the RF coaxial connector to ensure the accuracy of the air tightness test of the entire RF coaxial connector, without the need to set up an additional air inlet channel.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, the root of some existing high-frequency induction welding RF coaxial connectors does not have an anti-bending structure. If the connector is accidentally bent during use, the connector is prone to damage, affecting the stability of signal transmission. Furthermore, the connecting nut after the male and female ends of the high-frequency induction welding RF coaxial connector are connected is not easily positioned. Especially in industrial equipment applications, the vibration generated by the industrial equipment can easily cause the nut to loosen, leading to signal interruption.

[0006] To address this, a high-frequency induction welding radio frequency coaxial connector is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a high-frequency induction welding radio frequency coaxial connector, which can solve the problems of the lack of anti-bending structure at the root of the connecting wire of some existing high-frequency induction welding radio frequency coaxial connectors. When the connecting wire is accidentally bent during use, it is easy to damage the connecting wire, affecting the stability of signal transmission. In addition, the connecting nut after the male and female ends of the high-frequency induction welding radio frequency coaxial connector are connected is not easy to limit. Especially in industrial equipment application scenarios, the vibration generated by industrial equipment can easily cause the nut to loosen, which can easily lead to the interruption of the connection signal.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a high-frequency induction welding radio frequency coaxial connector, comprising a female radio frequency coaxial connector body, a male radio frequency coaxial connector body, a connecting nut, and two connecting wire bodies. A connecting plate is provided on opposite sides of both the female and male radio frequency coaxial connector bodies, and a rubber sleeve is fixedly connected to opposite sides of both connecting plates. A reinforcing mechanism is provided on the surface of the rubber sleeve, and a limiting mechanism is provided on the top of the connecting nut.

[0009] The limiting mechanism includes a pull block, a tension spring, a slide rod, a pressure plate, and a silicone block. The bottom of the pull block is fixedly connected to the top of the slide rod. The tension spring is movably sleeved on the surface of the slide rod, and the top of the tension spring is fixedly connected to the bottom of the pull block. The bottom of the slide rod is fixedly connected to the top of the pressure plate. The top of the silicone block is fixedly connected to the bottom of the pressure plate, and the bottom of the silicone block is in close contact with the surface of the connecting nut.

[0010] Preferably, the reinforcing mechanism includes a plurality of nylon filaments, a corrosion-resistant layer, and a wear-resistant layer. The nylon filaments are embedded inside the rubber sleeve, the corrosion-resistant layer is disposed on the surface of the rubber sleeve, and the wear-resistant layer is disposed on the surface of the corrosion-resistant layer.

[0011] Preferably, the corrosion-resistant layer is uniformly coated on the surface of the rubber sleeve, and the material of the corrosion-resistant layer is a polyurea coating.

[0012] Preferably, the wear-resistant layer is uniformly coated on the surface of the corrosion-resistant layer, and the wear-resistant layer is made of polyurethane coating.

[0013] Preferably, a fixing frame is fixedly connected to the top of the rear connecting plate, the slide rod is slidably connected inside the fixing frame, and the bottom of the tension spring is fixedly connected to the top of the fixing frame.

[0014] Preferably, the connecting plate has a through hole, the rubber sleeve is connected to the through hole, and the connecting wire body passes through the through hole and the rubber sleeve in sequence on the side near the through hole and extends to the outside of the rubber sleeve.

[0015] Preferably, screws are provided at the four corners of the opposite side of the female and male RF coaxial connector bodies. The screws pass through the female and male RF coaxial connector bodies respectively and are connected to the internal threads of the connecting plate.

[0016] Preferably, the connecting plate has four mounting holes inside, which are evenly distributed inside the connecting plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application sets a limit mechanism, which pulls the block upward to move the slide bar, pressure plate and silicone block upward, and the tension spring is stretched. After the connecting nut is threadedly connected to the female body of the RF coaxial connector, the block is released to reset the tension spring. The silicone block is tightly in contact with the connecting nut, and the friction is used to prevent it from loosening due to vibration and rotation, thus ensuring stable signal connection.

[0019] 2. This application incorporates a reinforcing mechanism to prevent the connecting cable from bending by using the elasticity of the rubber sleeve. The internal nylon filaments enhance the structural strength, while the surface polyurea coating provides corrosion resistance and the polyurethane coating provides wear resistance, extending the lifespan of the rubber sleeve and ensuring that the connecting cable itself is effectively and permanently protected against bending.

[0027] 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.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A high-frequency induction welding radio frequency coaxial connector includes a female radio frequency coaxial connector body 1, a male radio frequency coaxial connector body 2, a connecting nut 5, and two connecting wire bodies 11. A connecting plate 3 is provided on opposite sides of the female radio frequency coaxial connector body 1 and the male radio frequency coaxial connector body 2. A rubber sleeve 8 is fixedly connected to opposite sides of the two connecting plates 3. A reinforcing mechanism 9 is provided on the surface of the rubber sleeve 8. A limiting mechanism 6 is provided on the top of the connecting nut 5.

[0030] The limiting mechanism 6 includes a pull block 601, a tension spring 602, a slide rod 603, a pressure plate 604, and a silicone block 605. The bottom of the pull block 601 is fixedly connected to the top of the slide rod 603. The tension spring 602 is movably sleeved on the surface of the slide rod 603. The top of the tension spring 602 is fixedly connected to the bottom of the pull block 601. The bottom of the slide rod 603 is fixedly connected to the top of the pressure plate 604. The top of the silicone block 605 is fixedly connected to the bottom of the pressure plate 604. The bottom of the silicone block 605 is in close contact with the surface of the connecting nut 5.

[0031] In this embodiment: the connecting cable body 11 is inserted into the cable hole 12 and the rubber sleeve 8. The rubber sleeve 8 prevents bending due to its elasticity. The reinforcing mechanism 9 has internal nylon filaments 901 to enhance strength, a polyurea coating on the surface for corrosion resistance, and a polyurethane coating on top for increased wear resistance, all contributing to extended lifespan. The RF coaxial connector female body 1 and the RF coaxial connector male body 2 are respectively fixed to the rear and front connecting plates 3 by four screws 4. The rear connecting plate 3 is fixed in the mounting position by the mounting hole 10 and external bolts. Pulling the pull block 601 moves the silicone block 605 upward, at which point the tension spring 602 is stretched. Then, the connecting nut 5 is threaded onto the RF coaxial connector female body 1, and the pull block 601 is released. The tension spring 602 resets, allowing the silicone block 605 to press firmly against the connecting nut 5. This friction helps prevent loosening due to vibration. The front connecting plate 3 is fixed by the mounting hole 10 and external bolts, completing a stable connection. This solves the problem that some existing high-frequency induction welding RF coaxial connectors do not have an anti-bending structure at the root of the connecting wire. If the connecting wire is accidentally bent during use, it is easy to be damaged, affecting the stability of signal transmission. Furthermore, the connecting nut of the high-frequency induction welding RF coaxial connector male and female connectors is not easy to limit, especially in industrial equipment applications where vibrations can easily cause the nut to loosen, leading to signal interruption.

[0032] Specifically, such as Figure 6As shown, the reinforcing mechanism 9 includes several nylon filaments 901, a corrosion-resistant layer 902, and a wear-resistant layer 903. The nylon filaments 901 are embedded inside the rubber sleeve 8, the corrosion-resistant layer 902 is disposed on the surface of the rubber sleeve 8, and the wear-resistant layer 903 is disposed on the surface of the corrosion-resistant layer 902.

[0033] Specifically, such as Figure 6 As shown, the corrosion-resistant layer 902 is uniformly coated on the surface of the rubber sleeve 8, and the material of the corrosion-resistant layer 902 is a polyurea coating.

[0034] Specifically, such as Figure 6 As shown, the wear-resistant layer 903 is uniformly coated on the surface of the corrosion-resistant layer 902, and the material of the wear-resistant layer 903 is a polyurethane coating.

[0035] In this embodiment: the reinforcing mechanism 9 enhances the structural strength of the rubber sleeve 8 through internal nylon filaments 901, and the surface is sequentially provided with a polyurea corrosion-resistant layer 902 and a polyurethane wear-resistant layer 903, which effectively improves the corrosion resistance, wear resistance and structural stability of the rubber sleeve 8, extends its service life, and does not affect the elasticity of the rubber sleeve 8, thus ensuring the anti-bending protection effect on the connecting wire body 11.

[0036] Specifically, such as Figure 3 As shown, a fixing frame 7 is fixedly connected to the top of the rear connecting plate 3, a slide rod 603 is slidably connected inside the fixing frame 7, and the bottom of the tension spring 602 is fixedly connected to the top of the fixing frame 7.

[0037] Specifically, such as Figure 3 and Figure 5 As shown, the connecting plate 3 has a wire hole 12 inside, the rubber sleeve 8 is connected to the wire hole 12, and the connecting wire body 11 passes through the wire hole 12 and the rubber sleeve 8 in sequence on the side near the wire hole 12 and extends to the outside of the rubber sleeve 8.

[0038] In this embodiment: the fixing frame 7 provides stable sliding support for the slide rod 603, and together with the tension spring 602, the silicone block 605 can reliably press the connecting nut 5. The wire hole 12 is connected to the rubber sleeve 8, ensuring that the connecting wire body 11 can pass through smoothly and be wrapped by the rubber sleeve 8, which not only ensures smooth connection, but also enhances the targeted protection against bending.

[0039] Specifically, such as Figure 3 and Figure 4 As shown, screws 4 are provided at the four corners of the opposite side of the female connector body 1 and the male connector body 2 of the RF coaxial connector. The screws 4 pass through the female connector body 1 and the male connector body 2 of the RF coaxial connector, respectively, and are connected to the internal threads of the connecting plate 3.

[0040] Specifically, such as Figure 3As shown, the connecting plate 3 has four mounting holes 10 inside, which are evenly distributed inside the connecting plate 3.

[0041] In this embodiment, four screws 4 can connect the female RF coaxial connector body 1 and the male RF coaxial connector body 2 to the two connecting plates 3 respectively, achieving a stable assembly. The four evenly distributed mounting holes 10 facilitate fixing the connecting plates 3 in the installation position with external bolts, thereby improving the overall connection stability and installation firmness of the female RF coaxial connector body 1 and the male RF coaxial connector body 2, and adapting to vibration environments.

[0042] Working principle: By passing the connecting wire body 11 through the wire hole 12 and the rubber sleeve 8, the rubber sleeve 8 uses its own elasticity to wrap around the connecting wire body 11, achieving anti-bending protection for the connecting wire body 11. In the reinforcing mechanism 9, several nylon threads 901 embedded inside the rubber sleeve 8 enhance the structural strength of the rubber sleeve 8. The corrosion-resistant layer 902 is a polyurea coating uniformly coated on the surface of the rubber sleeve 8, providing good corrosion resistance. The wear-resistant layer 903 is a polyurethane coating uniformly coated on the surface of the corrosion-resistant layer 902, further improving the wear resistance of the rubber sleeve 8. Through the combined action of the nylon threads 901, the corrosion-resistant polyurea coating 902, and the wear-resistant polyurethane coating 903, the rubber sleeve's lifespan is extended. To extend the service life of the set 8, the four corners of the female RF coaxial connector body 1 and the male RF coaxial connector body 2 on opposite sides are threaded to the corresponding connecting plates 3 by screws 4, thereby achieving a fixed connection between the female RF coaxial connector body 1 and the male RF coaxial connector body 2 and the connecting plates 3. Then, external bolts are used to pass through the mounting holes 10 on the rear connecting plate 3 to install the rear connecting plate 3 in the preset installation position. After that, the pull block 601 is pulled upward, and the pull block 601 drives the slide rod 603 to slide upward inside the fixing frame 7. The slide rod 603 drives the pressure plate 604 and the silicone block 605 to move upward, and at the same time, the tension spring 602 is stretched. At this time, the connecting nut 5 is threaded to the female RF coaxial connector body 1. After connecting the male connector body 2 and the female connector body 1 of the RF coaxial connector, release the pull block 601. The tension spring 602 resets, causing the pull block 601, slide rod 603, pressure plate 604, and silicone block 605 to move downwards. This allows the bottom of the silicone block 605 to make tight contact with the surface of the connecting nut 5. The friction between the silicone block 605 and the connecting nut 5 prevents the connecting nut 5 from rotating due to vibration, thus ensuring the stability of the signal connection. Finally, the front connecting plate 3 is fixed by passing an external bolt through the mounting hole 10 on the front connecting plate 3, thereby completing the connection of the high-frequency induction welding RF coaxial connector male connector body 2 and RF coaxial connector female connector body 1. This design ensures a stable connection and fixation, guaranteeing stable operation. It addresses the issue that some existing high-frequency induction welding RF coaxial connectors lack a bend-resistant structure at the base of the connector cable, making them prone to damage after accidental bending during use, thus affecting signal transmission stability. Furthermore, the connecting nut after the male and female connectors of the high-frequency induction welding RF coaxial connector are not easily positioned, especially in industrial equipment applications where vibrations can easily cause the nut to loosen, leading to signal interruption. It should be noted that both the female connector body 1 and the male connector body 2 of the RF coaxial connector are existing, published, and mature technologies, and their basic mechanisms will not be elaborated here.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
