Description

Technical Field

[0001] This utility model relates to the field of radio frequency connector technology, specifically a novel high-reliability radio frequency connector. Background Technology

[0002] With the rapid development of China's electronic technology and the continuous expansion of industries such as computer, communications, military, aerospace, and shipbuilding, the demand for radio frequency cable assemblies will also grow rapidly, and the requirements for connectors will become increasingly stringent. The use of high-reliability connectors enhances the reliability of radio frequency assemblies. High-reliability connectors are only suitable for double-shielded radio frequency cables.

[0003] A search revealed a radio frequency connector in Chinese utility model patent CN202023165090.X, comprising an external structure for electrical connection with an external coaxial cable and an end face structure mounted on the front end of the external structure. The end face structure includes a columnar outer conductor electrically connected to the outer conductor of the coaxial cable, and an inner conductor electrically connected to the inner conductor of the coaxial cable and positioned along the central axis of the outer conductor. The outer conductor of the end face structure provides an end face with an annular groove dividing it into an inner step and an outer step. A flexible conductive element is disposed within the annular groove. This radio frequency connector has a small size and strong versatility. The test grounding shielding effect is good, the test error is small, and it is suitable for mass testing. Although this RF connector is highly versatile and has a good test grounding shielding effect, after being assembled with the RF cable, after multiple insertions and removals, bending, or when the tail end is subjected to large forces, the connection between the RF cable shielding layer and the cable may break. The conventional connector shell length is 6mm, and it is only crimped once. It cannot be extended and crimped twice to reinforce the shielding layer connection. Therefore, a new type of high-reliability RF connector is proposed that can reinforce and extend the connection between the connector and the cable, crimp twice to avoid shielding layer breakage, and increase the reliability of the cable and connector. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel high-reliability radio frequency connector that can reinforce the connection between the connector and the cable, prevent the shielding layer from breaking, and facilitate long-term use. It solves the problem that the connection between the radio frequency cable shielding layer and the cable breaks after multiple insertions and removals, bending, or when the tail end is subjected to large forces after the radio frequency cable is assembled.

[0005] To achieve the above-mentioned purpose of reinforcing the connection between the connector and the cable, preventing the shielding layer from breaking, and facilitating long-term use, this utility model provides the following technical solution: a novel high-reliability radio frequency connector, including a protective shell, a plug ring welded to the left side of the protective shell, and a reinforcement mechanism provided on the outside of the protective shell;

[0006] The reinforcement mechanism includes an insulating block, a pin, a crimping block, a connecting tube, an extension tube one, an extension tube two, a crimping cylinder one, and a crimping cylinder two. An insulating block is provided inside the protective shell. A pin is fixedly connected to the left side of the insulating block. A crimping block is fixedly installed on the right side of the protective shell. A connecting tube is fixedly installed on the right side of the insulating block. An extension tube one is provided on the right side of the protective shell. An extension tube two is fixedly installed on the right side of the extension tube one. A crimping cylinder one is provided outside the extension tube one. A crimping cylinder two is provided outside the extension tube two.

[0007] Furthermore, an internally threaded retaining ring is fixedly installed inside the protective shell, and an external thread is provided on the outside of the insulating block.

[0008] Furthermore, the connecting pipe has an installation hole inside, which is adapted to the connecting pipe.

[0009] Furthermore, a connecting ring is welded to the left side of the second crimping cylinder, and the second crimping cylinder is welded to the first crimping cylinder through the connecting ring.

[0010] Furthermore, an open ring is fixedly connected to the right side of the second crimping cylinder, and the inside of the open ring has an arc surface.

[0011] Furthermore, a locking block is welded to the right side of the protective shell, and the extension tube is welded to the protective shell through the locking block.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This new high-reliability RF connector features a reinforcement mechanism. When connecting the connector to a double-shielded RF cable, both the inner shielding layer at the front and the outer shielding layer at the rear are peeled off using a tool. The inner shielding layer is then inserted into extension tube one and passes through the connecting tube, while the outer shielding layer is positioned approximately inside extension tube two. Crimping cylinder one and crimping cylinder two are then performed separately, providing double reinforcement to prevent breakage of the double shielding layers and unstable cable connections. This ensures a stable connection at the tail end, allowing it to withstand repeated insertions, removals, and bending. This reinforcement mechanism strengthens the connection between the connector and the cable, preventing shielding layer breakage and facilitating long-term continuous use.

[0019] 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.

[0020] Please see Figure 1-4 A novel high-reliability radio frequency connector in this embodiment includes a protective shell 1, a plug ring 2 welded to the left side of the protective shell 1, and a reinforcement mechanism 3 provided on the outside of the protective shell 1.

[0021] The reinforcement mechanism 3 includes an insulating block 301, a pin 302, a crimping block 303, a connecting tube 304, an extension tube 1 305, an extension tube 2 306, a crimping cylinder 1 307, and a crimping cylinder 2 308. The insulating block 301 is installed inside the protective shell 1. The pin 302 is fixedly connected to the left side of the insulating block 301. The crimping block 303 is fixedly installed on the right side of the protective shell 1. The connecting tube 304 is fixedly installed on the right side of the insulating block 301. An extension tube 1 305 is installed on the right side of the protective shell 1. An extension tube 2 306 is fixedly installed on the right side of the extension tube 1 305. A crimping cylinder 1 307 is installed outside the extension tube 1 305. A crimping cylinder 2 308 is installed outside the extension tube 2 306.

[0022] In the implementation of the case, an internally threaded retaining ring 4 is fixedly installed inside the protective shell 1, and an external thread 401 is provided on the outside of the insulating block 301. By setting the internally threaded retaining ring 4 and the external thread 401, the insulating block 301 can be threadedly connected to the inside of the protective shell 1, which is convenient for disassembly and replacement.

[0023] In the case implementation, a connecting ring 6 is welded to the left side of the second crimping cylinder 308. The second crimping cylinder 308 is welded to the first crimping cylinder 307 through the connecting ring 6. By setting the connecting ring 6, the first crimping cylinder 307 and the second crimping cylinder 308 can be integrated as a whole, which helps to enhance stability.

[0024] In the implementation of the case, an open ring 7 is fixedly connected to the right side of the crimping cylinder 2 308. The inside of the open ring 7 is provided with an arc surface 701. By setting the open ring 7 and the arc surface 701, it is convenient to extend the peeled inner shielding layer and the rear outer shielding layer into the inside of the crimping cylinder 1 307 and the crimping cylinder 2 308.

[0025] When implementing this procedure, please follow these steps:

[0026] 1) When it is necessary to connect the connector to the double-shielded RF cable, use a tool to peel off both the inner shielding layer at the front and the outer shielding layer at the back of the cable.

[0027] 2) Then the inner shielding layer is inserted into the extension tube 305 and passes through the connecting tube 304, and the outer shielding layer is located approximately inside the extension tube 306.

[0028] 3) Then crimp the crimping cylinder 307 and the crimping cylinder 308 separately;

[0029] 4) Finally, double fixing prevents the double shielding layer from breaking and the cable connection from becoming unstable, making the tail end connection stable and able to withstand multiple insertions, removals and bends.

[0030] In summary, this novel high-reliability RF connector, through the reinforcement mechanism 3, allows for the removal of both the inner shielding layer and the outer shielding layer of the cable when connecting the connector to a double-shielded RF cable. The inner shielding layer is then inserted into extension tube 305 and passes through connecting tube 304, while the outer shielding layer is positioned approximately inside extension tube 306. Crimping is then performed on crimping cylinders 307 and 308 respectively, providing double fixation to prevent breakage of the double shielding layer and unstable cable connection. This ensures a stable connection at the tail end, allowing it to withstand repeated insertions, removals, and bending. The reinforcement mechanism 3 strengthens the connection between the connector and the cable, preventing shielding layer breakage and facilitating long-term continuous use.
