Description

Technical Field

[0001] The utility model relates to the technical field of cable connection, in particular to a 2.4mm connector. Background Art

[0002] 2.4mm connectors are widely used in high-frequency signal transmission systems, such as wireless communications, radar, microwave measurement, and instrumentation. These connectors are known for their precise impedance matching and excellent signal integrity, ensuring low-loss and high-reliability signal transmission in high-frequency applications. With the continuous development of wireless communication technology, the performance requirements for connectors are getting higher and higher, especially in higher frequency bands and more complex electromagnetic environments. The performance of connectors in terms of impedance matching, signal integrity, and installation convenience is particularly important.

[0003] However, in actual use, the traditional 2.4mm connector has some defects. For example, the existing 2.4mm connector may not be ideal in impedance matching, resulting in increased reflection and loss during signal transmission. In addition, the traditional connector is prone to the problem of the outer conductor getting stuck during cable welding, affecting the efficiency of installation and maintenance. At the same time, the complex structure and high cost are also a major obstacle to the practical application of traditional connectors. These problems limit the wide application and practical effect of 2.4mm connectors in high-frequency signal transmission. Therefore, we provide a 2.4mm connector. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and provide a 2.4mm connector.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a 2.4mm connector, comprising: a screw sleeve mechanism, the screw sleeve mechanism comprises a hexagonal sleeve, an embedded circular tube is arranged in the hexagonal sleeve, a snap groove is dug in the embedded circular tube, an external guide mechanism is arranged in the snap groove, the external guide mechanism comprises an embedded tube, a snap sleeve is arranged on the outer surface of the embedded tube, a threading tube is arranged in the embedded tube, a cable mechanism is arranged in the threading tube, the cable mechanism comprises an outer conductor, an insulating layer is arranged in the outer conductor, and an inner conductor is arranged in the insulating layer.

[0006] As a preferred implementation, the outer surface of the embedded circular tube is nested in the hexagonal sleeve.

[0007] As a preferred implementation, the outer surfaces of the embedded tube and the buckle sleeve in the outer guide mechanism are both nested and buckled in the buckle groove.

[0008] As a preferred implementation, the inner surface of the buckle sleeve is nested in the outer surface of the embedded tube.

[0009] As a preferred implementation, the inner surface of the insulating layer is attached to the outer surface of the inner conductor.

[0010] As a preferred implementation, the inner surface of the outer conductor is nested in the outer surface of the insulating layer, and the outer surface of the outer conductor is nested in the wire threading tube.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] The utility model increases the impedance in the trapezoidal gap of the outer conductor to make the overall impedance matching better. When connecting, the two ends of the connector are docked with the equipment, and the screw sleeve mechanism is rotated to fix the hexagonal sleeve to ensure that there is no looseness after locking. Then, a power-on test and a detailed electrical performance test are performed to ensure that the signal transmission is normal and meets the standards. During use, the connector is regularly checked and cleaned to ensure its stability and signal transmission quality. Three gaps are provided at the tail to prevent the cable from getting stuck with the outer conductor during welding. No clamping ring is used between the entire connector and the cable mechanism, so the structure is simpler and the cost is low. The cable insulation layer leaves a long (2.3mm) cable outer body to make the cable impedance transition smoother, which improves its practicality in actual use as a whole.

[0026] Example 1

[0027] like Figure 1-4As shown, the utility model provides a technical solution: a 2.4mm connector, including: a screw sleeve mechanism 1, the screw sleeve mechanism 1 includes a hexagonal sleeve 11, an embedded round tube 12 is provided in the hexagonal sleeve 11, a buckle groove 13 is dug in the embedded round tube 12, an outer guide mechanism 2 is provided in the buckle groove 13, the outer guide mechanism 2 includes an embedded tube 21, a buckle sleeve 22 is provided on the outer surface of the embedded tube 21, a threading tube 23 is provided in the embedded tube 21, a cable mechanism 3 is provided in the threading tube 23, and the cable mechanism 3 includes an outer conductor 31 An insulating layer 32 is provided in the outer conductor 31, an inner conductor 33 is provided in the insulating layer 32, the outer surface of the embedded circular tube 12 is nested in the hexagonal sleeve 11, the outer surfaces of the embedded tube 21 and the snap sleeve 22 in the outer guide mechanism 2 are both nested and snapped in the snap groove 13, the inner surface of the snap sleeve 22 is nested in the outer surface of the embedded tube 21, the inner surface of the insulating layer 32 is applied to the outer surface of the inner conductor 33, the inner surface of the outer conductor 31 is nested in the outer surface of the insulating layer 32, and the outer surface of the outer conductor 31 is nested in the threading tube 23.

[0028] In this embodiment, in the actual use of the 2.4mm connector, first confirm that all parts are complete and free of defects. The embedded circular tube 12 is nested in the hexagonal sleeve 11 to ensure its stability. Then the embedded tube 21 is inserted into the embedded circular tube 12, the buckle sleeve 22 is embedded in the outer surface of the embedded tube 21, and locked in the buckle groove 13. Next, the inner conductor 33 is inserted into the insulating layer 32, and then the insulating layer 32 is embedded in the outer conductor 31, and finally the outer conductor 31 is inserted into the threading tube 23 to ensure that all parts fit tightly. When connecting, dock the two ends of the connector with the equipment, rotate the screw sleeve mechanism 1 to fix the hexagonal sleeve 11, and ensure that there is no looseness after locking. Subsequently, a power-on test and a detailed electrical performance test are performed to ensure that the signal transmission is normal and meets the standards. Check and clean the connector regularly during use to ensure its stability and signal transmission quality. Through these steps, it is ensured that the 2.4mm connector achieves the expected effect during use.

[0029] Working principle:

[0030] like Figure 1-4 As shown, in the actual application of the 2.4mm connector, it is first necessary to confirm that all parts are complete and free of defects. Ensuring the integrity of the parts is a key step, as any defects or missing parts may affect the performance of the connector. First, the embedded round tube 12 is nested in the hexagonal sleeve 11 to ensure its stability. This step requires careful inspection of the fit between the embedded round tube 12 and the hexagonal sleeve 11 to ensure that there is no looseness or misalignment.

[0031] Next, insert the embedded tube 21 into the embedded circular tube 12, ensuring that the embedded tube 21 is fully inserted and does not shake. Then, embed the buckle sleeve 22 on the outer surface of the embedded tube 21 and lock it in the buckle groove 13. In this step, special attention should be paid to the close fit between the buckle sleeve 22 and the buckle groove 13 to ensure that the buckle sleeve 22 is firmly fixed and will not fall off due to external force.

[0032] After completing the above steps, the inner conductor 33 is inserted into the insulating layer 32, and it is ensured that the inner conductor 33 is completely embedded in the insulating layer 32. Next, the insulating layer 32 is embedded in the outer conductor 31. In this step, it is necessary to ensure that there is no gap between the insulating layer 32 and the outer conductor 31 to ensure a tight fit. Finally, the outer conductor 31 is inserted into the threading tube 23 to ensure that all parts are tightly combined. The purpose of this series of steps is to ensure the structural integrity of the connector, thereby ensuring the stability of signal transmission.

[0033] When connecting, dock the two ends of the connector with the device. Rotate the screw sleeve mechanism 1 to fix the hexagonal sleeve 11 to ensure that it is not loose after being locked. In this step, it is necessary to apply appropriate force when rotating the screw sleeve to ensure that the hexagonal sleeve 11 is completely locked, thereby preventing the connector from loosening due to vibration or external force during use.

[0034] After the connector is installed, a power-on test and a detailed electrical performance test are performed. These tests are designed to ensure that the signal transmission is normal and meets relevant standards. The power-on test can check the conductivity of the connector, while the electrical performance test can detect its signal transmission quality, including signal attenuation, impedance matching and other indicators.

[0035] In actual use, regular inspection and cleaning of the connector is the key to maintaining its performance. Regular inspection can find and solve potential problems, and cleaning can prevent dust and impurities from affecting the connector. Through these maintenance steps, the stability and signal transmission quality of the 2.4mm connector can be ensured.

[0036] In summary, through the above detailed steps, we can ensure that the 2.4mm connector can achieve the expected effect in actual use. Whether in installation, testing or daily maintenance, we need to strictly follow the specifications to ensure the best performance and longest life of the connector. Through these meticulous steps, users can use the 2.4mm connector with confidence, ensuring its reliability and efficiency in various applications.
