Description

Technical Field

[0001] This utility model relates to the field of radio frequency coaxial connector technology, specifically a quick-locking radio frequency coaxial connector. Background Technology

[0002] RF coaxial connectors are specialized connectors used to transmit radio frequency signals. They maintain signal integrity and minimize signal loss through coaxial cables and are widely used in wireless communication, broadcasting, radar systems, medical equipment, and test and measurement equipment. They are crucial because they can effectively manage reflections and impedance matching during signal transmission.

[0003] Quick-lock RF coaxial connectors are RF connectors designed for fast and secure connections. These connectors employ a special locking mechanism that enables quick, simple, and reliable connections while taking up little space and requiring no tools, making pairing speeds typically 10 times faster than standard screw-in connectors.

[0004] Existing snap-fit ​​connectors achieve quick fixation of male and female heads through the cooperation of springs and snap-fit ​​components. This method is simple and quick to install. However, without a corresponding quick disassembly mechanism, the practicality and ease of maintenance will be greatly reduced in later maintenance and operation due to the possible insufficient locking strength or difficulty in disassembly of snap-fit ​​connectors. Therefore, a quick-locking RF coaxial connector is proposed to address the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-locking RF coaxial connector to solve the problem that without a corresponding quick disassembly mechanism, the practicality and ease of maintenance of the snap-fit ​​connector will be greatly reduced in later maintenance and operation due to insufficient locking strength or difficulty in disassembly.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A quick-locking RF coaxial connector includes a female connector and a female housing. The female housing is fixedly connected to the right side of the female connector, and a female interface end is also fixedly connected to the right side of the female connector. The upper and lower ends of the female housing have slots, and the front and rear ends of the female housing have rail grooves. A male housing assembly is mounted on the outside of the female housing, and a torsion assembly is rotatably connected to the outside of the male housing assembly. A male connector is fixedly connected to the right side of the male housing assembly. The torsion assembly includes a rotating ring, and a limiting device is fixedly connected to the inner side of the left end of the rotating ring. The rotating ring has a magnetic block fixedly connected to both its front and rear ends, and an internal block fixedly connected to its upper end. The male connector housing assembly includes a male connector housing, a rail fixedly connected to the inner side of the male connector housing, a spring fixedly connected to the outer side of the male connector housing, a spring groove on the inner side of the male connector housing, an arc-shaped groove on the upper end of the male connector housing, a linear spring fixedly connected to one side of the spring groove on the male connector housing, a magnetic plate fixedly connected to one end of the linear spring, a ball rod fixedly connected to the inner side of one end of the magnetic plate, and a rolling ball rotatably connected to the outer side of the ball rod.

[0008] As a further optimization of this utility model, the female connector cover is a hollow cylinder, which is embedded inside the male connector housing, and the male connector plug is installed inside the female connector interface.

[0009] The slot is cylindrical and extends through the outside of the female head cover. The rail is rectangular and extends through the right end of the female head cover. The rail is rectangular and slides against the rail of the female head cover via the rail.

[0010] Both the rotating ring and the limiting ring are annular in shape. The rotating ring is sleeved on the outside of the male connector shell. The male connector shell has an annular groove near the limiting ring. The rotating ring is rotatably connected to the annular groove in the male connector shell through the limiting ring. There is a gap between the inner side of the rotating ring and the outer side of the male connector shell. One end of the spring is fixedly connected to the inner side of the rotating ring.

[0011] The arc-shaped groove is arc-shaped and penetrates the outside of the male head shell. The bottom end of the built-in block is embedded in the inside of the arc-shaped groove.

[0012] The spring groove is shaped like a three-section cylinder. The spring groove penetrates the interior of the male connector shell. There are two spring grooves. The magnetic plate is slidably connected inside the spring groove of the male connector shell. The magnetic plate has a groove on the inner side near the rolling ball. The magnetic plate protrudes from the outside of the male connector shell.

[0013] The ball has a straight hole on its inner side near the stick, and the outer side of the ball fits into the slot on the outer cover of the female head. The magnetic plate is engaged inside the slot, and the end of the magnetic block near the outer shell of the male head is magnetically attracted to the magnetic plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the device enables rapid installation and disassembly of the RF coaxial connector through the torsion assembly and the male connector housing assembly. By pushing the male connector, the male connector housing slides inside the female connector housing, and the male connector plug is inserted into the interior of the female connector interface. The locking between the male connector housing and the female connector housing is achieved through the engagement of the magnetic plate. When disassembly is required, rotating the rotating ring drives the internal block and the magnetic block to rotate. The magnetic attraction of the magnetic block causes the magnetic plate to approach and be stored inside the spring groove, thereby quickly pulling the male connector housing out of the female connector housing, completing the disassembly. This design improves the ease of connector installation and greatly simplifies the disassembly process during later maintenance, enhancing practicality and ease of maintenance.

[0028] 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.

[0029] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0030] Please see Figure 1-8 This utility model provides a technical solution:

[0031] A quick-locking RF coaxial connector includes a female connector 1 and a female housing 2. The female housing 2 is fixedly connected to the right side of the female connector 1, and a female interface end 3 is also fixedly connected to the right side of the female connector 1. The upper and lower ends of the female housing 2 have slots 4, and the front and rear ends of the female housing 2 have rail grooves 5. A male housing assembly 7 is mounted on the outside of the female housing 2. A torsion assembly 6 is rotatably connected to the outside of the male housing assembly 7. A male connector 8 is fixedly connected to the right side of the male housing assembly 7. The torsion assembly 6 includes a rotating ring 61, with a limiting ring 62 fixedly connected to the inner side of the left end of the rotating ring 61. The rotating ring 61 has a front... Both ends are fixedly connected to a magnetic block 63. The upper end of the rotating ring 61 is fixedly connected to an internal block 64. The male head housing assembly 7 includes a male head housing 71. A rail 72 is fixedly connected to the inner side of the male head housing 71. A spring 73 is fixedly connected to the outer side of the male head housing 71. A spring groove 74 is opened on the inner side of the male head housing 71. An arc-shaped groove 75 is opened at the upper end of the male head housing 71. A linear spring 76 is fixedly connected to one side of the spring groove 74 opened in the male head housing 71. A magnetic plate 77 is fixedly connected to one end of the linear spring 76. A ball stick 78 is fixedly connected to the inner side of one end of the magnetic plate 77. A ball ball 79 is rotatably connected to the outer side of the ball stick 78.

[0032] As a further implementation of this solution, the female head cover 2 is a hollow cylinder. The female head cover 2 is embedded inside the male head cover 71. The plug of the male connector 8 is installed inside the female head interface end 3. The slot 4 is cylindrical and extends through the outside of the female head cover 2. The rail groove 5 is rectangular and extends through the right end of the female head cover 2. The rail 72 is rectangular. The male head cover 71 slides and fits into the rail groove 5 of the female head cover 2 through the rail 72. After the rail 72 for fixing the male head cover 71 is aligned with the rail groove 5, the male head cover 71 and the female head cover 2 can be quickly connected. This serves to guide the installation of the male head cover 71 and ensure that the magnetic plate 77 can be engaged inside the slot 4.

[0033] As a further implementation of this solution, both the rotating ring 61 and the limiting ring 62 are annular in shape. The rotating ring 61 is sleeved on the outside of the male head shell 71. The male head shell 71 has an annular groove near the limiting ring 62. The rotating ring 61 is rotatably connected to the annular groove of the male head shell 71 through the limiting ring 62. There is a gap between the inner side of the rotating ring 61 and the outer side of the male head shell 71. One end of the spring 73 is fixedly connected to the inner side of the rotating ring 61, so that when operating the rotating ring 61, it can be limited by the limiting ring 62, so that the rotating ring 61 can drive the built-in block 64 and the magnetic block 63 to move simultaneously.

[0034] As a further implementation of this solution, the arc-shaped groove 75 is arc-shaped and penetrates the outside of the male head shell 71. The bottom end of the built-in block 64 is embedded in the inside of the arc-shaped groove 75, which facilitates the sliding of the built-in block 64 inside the arc-shaped groove 75, prevents the torque of the spring 73 from failing, and plays a role in limiting the rotation angle of the rotating ring 61.

[0035] As a further implementation of this solution, the spring groove 74 is shaped as a three-section cylinder. The spring groove 74 penetrates the interior of the male connector housing 71. There are two spring grooves 74. The magnetic plate 77 is slidably connected inside the spring groove 74 in the male connector housing 71. The magnetic plate 77 has a groove on the inner side near the ball 79. The magnetic plate 77 protrudes from the outside of the male connector housing 71. The elastic force of the linear spring 76 can push the magnetic plate 77 and the ball 79 to engage inside the female connector interface end 3, improving the ease of installation.

[0036] As a further implementation of this solution, the inner side of the ball 79 near the ball rod 78 has a straight hole, the outer side of the ball 79 is attached to one side of the slot 4 opened in the female head outer cover 2, the magnetic plate 77 is engaged in the inside of the slot 4, and the end of the magnetic block 63 near the male head outer shell 71 is magnetically attracted to the magnetic plate 77. Through the magnetic attraction of the magnetic block 63, the magnetic plate 77 and the ball 79 are stored in the inside of the spring groove 74, which improves the convenience of disassembly during maintenance.

[0037] Workflow: For easy installation and disassembly, align the groove 5 on the outer side of the female connector housing 2 with the rail 72 fixed on the inner side of the male connector housing 71, and push the male connector 8 towards the female connector 1. At this time, the male connector 8 causes the male connector housing 71 to slide inside the female connector housing 2, and the plug of the male connector 8 is inserted into the inside of the female connector interface end 3. When the ball bearing 79 contacts the outer side of the female connector housing 2, the ball bearing 79 drives the magnetic plate 77 to move, and the magnetic plate 77 compresses the linear spring 76, causing the magnetic plate 77 to slide. The ball 79 moves inside the spring groove 74, while the arc-shaped end of the magnetic plate 77 protrudes outside the spring groove 74. Simultaneously, the ball 79 rotates outside the ball rod 78, reducing friction during the movement of the male connector housing 71. When the ball 79 and magnetic plate 77 are aligned with the slot 4, under the elastic force of the linear spring 76, the ball 79 enters the slot 4, and the arc-shaped end of the magnetic plate 77 also enters the slot 4. At this point, the magnetic plate 77 engages inside the slot 4, acting as a clamp between the male connector housing 71 and the female connector outer cover 2. The locking function is then complete. For disassembly, rotating the rotating ring 61, which is rotatably connected to the male connector housing 71 via a limiting ring 62, limits the rotation of the ring 61. When the ring 61 rotates, it drives the internal block 64 and the magnetic block 63 to rotate simultaneously. The internal block 64 is located inside the arc-shaped groove 75. Under the torque of the spring 73, the front end of the internal block 64 remains tightly pressed against the inner front end of the arc-shaped groove 75. The arc-shaped groove 75 and the internal block 64 are designed to prevent the winding mechanism from shifting. When the torsion of the spring 73 fails, and the magnetic block 63 aligns with the magnetic plate 77, the magnetic plate 77 moves toward the magnetic block 63 under the magnetic attraction of the magnetic block 63. At this time, under the magnetic attraction, the ball 79 and the magnetic plate 77 are housed inside the spring groove 74, allowing the male connector 8 to be pulled out of the female connector housing 2 directly, thus completing the disassembly. The device improves the ease of installation and facilitates quick disassembly during later maintenance, enhancing practicality and convenience.
