Description

Technical Field

[0001] The utility model relates to the technical field of SMA, in particular to a tail structure of an SMA connector matched with LH240. Background Art

[0002] The SMA connector is a common radio frequency (RF) connector, usually used for signal transmission between RF devices and antennas. It is a threaded connector with a high frequency range and performance stability, so it is widely used in wireless communication and microwave applications.

[0003] The existing patent CN208970818U discloses an SMA connector and an SMA connector, wherein the SMA connector comprises: a shell, a conductive tube, a wire and a sealant; a channel with two ends passing through is formed in the shell, the conductive tube is located in the channel, the first end of the wire is inserted into the channel and connected to the conductive tube, and the second end of the wire protrudes out of the channel; a through hole is provided on the side wall of the shell, the connection between the first end of the wire and the conductive tube is opposite to the through hole, the through hole is used for injecting the sealant into the channel, and the shell, the conductive tube and the wire are all in contact with the sealant.

[0004] In order to solve the problem of water easily entering the SMA connector, this patent uses sealant to seal it, thereby achieving effective waterproofing.

[0005] However, in actual use, due to the large aperture of the tail of the outer conductor, when the SMA connector equipped with LH240 is processed into a cable assembly and tested, its frequency can only reach 3GHz, which obviously cannot meet the requirements of 6GHz high frequency use. However, when the aperture of the tail of the outer conductor is reduced, it is difficult to install the insulator from the tail, and it may even be impossible to install it at all, and it will have an adverse effect on the overall electrical performance of the connector.

[0006] Therefore, the utility model provides an SMA connector tail structure matched with LH240. Utility Model Content

[0014] The technical effect of adopting the above technical solution is: effectively preventing the medium between the outer conductor and the surrounding environment.

[0015] As a preferred implementation, the outer side of the insulating sheet is fixedly connected to the inner wall of the outer conductor.

[0016] The technical effect of adopting the above technical solution is: ensuring that the current does not directly contact the external environment through the conductor, thereby preventing potential electrical failures or short circuits.

[0017] As a preferred implementation, one end of the clamping spring away from the outer conductor is fixedly connected to the inner wall of the connecting nut.

[0018] The technical effect of adopting the above technical solution is: it ensures that the retaining spring will not loosen or fall off due to vibration or external force, thereby maintaining the durability of the connection.

[0019] As a preferred implementation, one end of the sealing ring away from the outer conductor contacts the interior of the connecting nut.

[0020] The technical effect of adopting the above technical solution is: ensuring that there are no leakage points at the connection.

[0021] As a preferred implementation, the spring piece is wavy in shape.

[0022] The technical effect of adopting the above technical solution is that the load and pressure can be distributed more evenly.

[0023] As a preferred embodiment, the internal thread of the connecting nut is connected to the outer side of the outer conductor.

[0024] The technical effect of adopting the above technical solution is that the connecting component can drive the central conductor to be connected firmly.

[0025] Compared with the prior art, the advantages and positive effects of the utility model are:

[0026] The utility model sets a boost component and a connection component structure, and the connection nut is screwed on the outside of the outer conductor to fix the retaining spring and enhance the accuracy of elastic transmission. At the same time, the nut contacts the sealing ring to ensure the sealing performance. The rotating nut is connected to the external thread ring to increase stability. Its wavy spring is deformed when tightened, providing reverse pressure to prevent loosening. The insulator is installed in the center conductor and the pressure ring is pressed in to complete the installation. The above design ensures a tight connection between the outer conductor and other components, avoiding the problem of unstable connection caused by loosening. In addition, by first installing the insulator into the outer conductor and then pressing the pressure ring into the tail, not only the problem of difficulty in installation caused by the overly large design aperture is solved, but also the overall electrical performance of the connector is not affected, so that the connector can work stably in a high-frequency environment of 6GHz.

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] like Figure 1 - Figure 2 As shown, this embodiment provides a technical solution: the tail structure of the SMA connector matched with the LH insulator 240 includes a conductor component 1, the inside of the conductor component 1 is fixedly connected with a boost component 2, the outside of the conductor component 1 is threadedly connected with a connection component 3, and the inside of the conductor component 1 is fixedly connected with the boost component 2. This structure firmly connects the boost component 2 to the conductor component 1 through a pressure ring 21, effectively enhancing the overall connection stability. The outside of the conductor component 1 is threadedly connected with the connection component 3. This threaded connection method ensures that the components can fit closely to prevent looseness, thereby improving the reliability of the connector;

[0037] The conductor assembly 1 includes an outer conductor 11, a center conductor 12 is arranged inside the outer conductor 11, and a boost assembly 2 includes a pressure ring 21, the outer side of the pressure ring 21 is fixedly connected to the inside of the conductor assembly 1, an insulating sheet 22 is fixedly connected to the outer side of the center conductor 12, and the outer side of the insulating sheet 22 is fixedly connected to the inner wall of the outer conductor 11, a retaining spring 23 is fixedly connected to the outer groove of the outer conductor 11, an insulator 24 is fixedly connected to the inside of the outer conductor 11, and a sealing ring 25 is fixedly connected to one side of the outer conductor 11. The center conductor 12 is arranged inside the outer conductor 11 in the conductor assembly 1, and the center conductor 12 ensures the effective transmission of the signal. The insulating sheet 22 is fixed on the outer side of the center conductor 12, further enhancing the electrical insulation performance. The pressure ring 21 included in the boost assembly 2 is fixed inside the conductor assembly 1. Through this fixing method, appropriate pressure can be applied inside the conductor assembly 1 to ensure the stable connection between the center conductor 12 and the insulating sheet 22. The design of the insulating sheet 22 not only ensures electrical insulation, but also improves mechanical strength. The retaining spring 23 provides additional mechanical locking to prevent the assembly from being displaced during use. A sealing ring 25 is fixedly connected to one side of the outer conductor 11. The sealing ring 25 provides an effective sealing effect when the connector is assembled to prevent the external environment from affecting the inside of the connector.

[0038] To prevent the connector from loosening during use, Figure 1 , Figure 3 and Figure 4As shown: in the present scheme, the connecting assembly 3 includes a connecting nut 31, the internal thread of the connecting nut 31 is connected to the outer side of the outer conductor 11, the end of the retaining spring 23 away from the outer conductor 11 is fixedly connected to the inner wall of the connecting nut 31, the end of the sealing ring 25 away from the outer conductor 11 is in contact with the inside of the connecting nut 31, the outer side of the connecting nut 31 is fixedly connected with an external thread ring 32, the outer side of the external thread ring 32 is threadedly connected with a rotating nut 33, and one end of the rotating nut 33 is fixedly connected with a spring piece 34, which is wavy in shape. The connecting nut 31 is connected to the outer side of the outer conductor 11 through the internal thread, ensuring a close fit between the components. The fixed connection between the retaining spring 23 and the connecting nut 31 increases the fixing points of the retaining spring 23, ensuring that the elasticity of the retaining spring 23 can be accurately transmitted, and the sealing ring 25 is in contact with the inside of the connecting nut 31, ensuring the sealing performance of the connector. The position of the connector can be easily adjusted and fixed by rotating the nut 33. The spring piece 34 is wavy in shape, and this shape design helps to provide greater reverse pressure when tightening to prevent loosening.

[0039] Working principle:

[0040] like Figure 1 - Figure 4 As shown:

[0041] During use: the connecting nut 31 is tightly screwed onto the outer side of the outer conductor 11 through its internal thread to form a preliminary connection. Then, due to the tightening of the connecting nut 31, its inner wall squeezes and fixes one end of the retaining spring 23, thereby ensuring the fixed position of the retaining spring 23 and enhancing the accuracy of its elastic transmission. At the same time, the interior of the connecting nut 31 contacts and squeezes one end of the sealing ring 25, ensuring the sealing performance of the connector and preventing the external environment from affecting the interior of the connector. Further, the rotating nut 33 is connected to the external thread ring 32 through its outer thread, allowing the user to increase the stability of the device by rotating the rotating nut 33. In this process, since the spring piece 34 at one end of the rotating nut 33 is designed to be wavy, when the rotating nut 33 is tightened, the spring piece 34 will be deformed, so that the spring piece 34 provides reverse pressure in the process of restoring the deformation, thereby preventing the connector from loosening during use. Subsequently, the insulator 24 is installed into the outer conductor 11 and the pressure ring 21 is pressed into the tail of the outer conductor 11 to complete the installation.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
