Description

Technical Field

[0001] This utility model relates to the field of radio frequency connector technology, and specifically to a connector head for a radio frequency connector. Background Technology

[0002] Radio frequency (RF) connectors are connection devices used for high-frequency signal transmission. They can stably and efficiently conduct RF current between devices, ensuring signal integrity and low loss. They are widely used in communications, radar, satellite and other fields. The existing RF connector connection methods are mainly snap-fit ​​and threaded connection.

[0003] For example, Chinese utility model patent with publication number CN201230088Y provides a radio frequency connector. The inner surface of the outer shell cavity of the radio frequency connector is provided with several threads to mate with the threads of the mating connector, and the connection is made through the threaded mating.

[0004] However, most existing RF connectors, whether snap-fit ​​or threaded, require rotation for installation and removal. When RF connectors are used for a long time, the internal elastic metal plates deform due to prolonged exposure to stretching and torsion. Rotation-based connections cannot separate the male and female connectors, requiring the replacement of the entire RF connector, which reduces maintenance efficiency and increases maintenance costs. Therefore, a new type of RF connector head is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes a connector head for an RF connector. This solves the problem mentioned in the background that most existing RF connectors, whether snap-fit ​​or threaded, require rotation for installation and disassembly. When RF connectors are used for a long time, the internal elastic metal sheet deforms due to prolonged exposure to stretching and torsional forces. The rotational connection method cannot separate the male and female heads, requiring the replacement of the entire RF connector, which reduces maintenance efficiency and increases maintenance costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a connector head for an RF connector, comprising a male head and a female head that can be connected to each other, wherein the male head is provided with a locking post, and the female head includes: A support sleeve is provided inside the female head and can be inserted into the male head; A locking sleeve is rotatably mounted on the support sleeve along its axis. The locking sleeve has a guide groove, and the end of the guide groove is connected to a slot through a guide groove. The slot is hook-shaped, and the locking pin can be engaged into the slot. The opening component is disposed on the locking sleeve and extends beyond the female head; and An elastic element is provided on the female end and can abut against the male end.

[0007] In a preferred embodiment, the opening component includes: A through groove is formed on the periphery of the female head; and An opening post is provided on the locking sleeve and is slidably engaged in the through groove and extends out of the through groove.

[0008] In a preferred embodiment, the outer circular surface of the support sleeve is provided with a positioning groove along its axial direction, and the end of the locking pin can pass through the locking sleeve and be engaged in the positioning groove.

[0009] In a preferred embodiment, the end of the guide groove is provided with a figure-eight flared opening that communicates with the outside.

[0010] In a preferred embodiment, the elastic element is an elastic washer or a spring.

[0011] In a preferred embodiment, the outer circular surface of the support sleeve is provided with an installation ring, and the locking sleeve is provided with an annular enlargement, which is rotatably sleeved on the installation ring.

[0012] Compared with the prior art, the present invention has the following beneficial effects: When using this connector, align the male and female connectors, then insert the female connector straight into the male connector along their axes. As the female connector is inserted, the locking pin engages in the guide groove until it enters the guide inclined groove. The guide inclined groove drives the locking sleeve to rotate as a whole. Then, release the male and female connectors, and the elastic element will cause the locking pin to engage in the slot, thus completing the connection between the male and female connectors. When it is necessary to open, the locking sleeve is controlled to rotate in the opposite direction by the opening component, so that the locking pin engages in the guide groove again, allowing the male and female connectors to be separated linearly. The entire assembly and disassembly process of this RF connector does not require rotation. Even if the internal metal plate deforms, the male and female connectors can be separated, effectively improving maintenance efficiency and reducing maintenance costs. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0016] Example: like Figure 1 , 3 As shown in Figure 4, this utility model provides a connector head for an RF connector, including a male connector 1 and a female connector 3 that can be connected to each other. The male connector 1 is provided with a locking post 2, and the female connector 3 is provided with a support sleeve 4 on its inner side. The support sleeve 4 can be inserted into the male connector 1. The support sleeve 4 is rotatably provided with a locking sleeve 9. The locking sleeve 9 is provided with a guide groove 10. The end of the guide groove 10 is connected to a slot 12 through a guide inclined groove 11. The slot 12 is hook-shaped, and the locking post 2 can be inserted into the slot 12. The female connector 3 is provided with an elastic element 6, which can abut against the male connector 1.

[0017] When connecting the male connector 1 and the female connector 3, they can be pushed together in a straight line to insert the female connector 3 into the male connector 1. During this connection, the locking pin 2 slides into the guide groove 10. The locking sleeve 9 rotates along its axis through the cooperation of the guide groove 11 and the locking pin 2, compressing the elastic element 6 until the locking pin 2 is locked into the slot 12. The elastic element 6 effectively prevents the locking pin 2 from disengaging from the slot 12. It is understood that in some preferred embodiments, the elastic element 6 is an elastic washer or a spring. Furthermore, a V-shaped flare 13 communicating with the outside is provided at the end of the guide groove 10. This flare 13 makes it easier for the locking pin 2 to be locked into the guide groove 10, eliminating the need for lengthy calibration by operators.

[0018] like Figure 1 , 3As shown in Figure 4, in this embodiment, the locking sleeve 9 is provided with an opening component extending out of the female connector 3. The opening component includes a through groove 8 formed on the periphery of the female connector 3. The locking sleeve 9 is provided with an opening post 15, which is slidably locked in the through groove 8 and extends out of the through groove 8. During installation, the locking sleeve 9 can be rotated by moving the opening post 15 so that the locking post 2 can be locked into the slot 12. When it is necessary to separate the male connector 1 and the female connector 3, the male connector 1 and the female connector 3 can be closed to compress the elastic element 6 again, and the opening post 15 can be moved so that the locking post 2 slides into the guide groove 11. Then the male connector 1 and the female connector 3 can be separated. The entire connection and separation process does not require rotating the male connector 1 or the female connector 3. Even if the internal metal piece of the RF connector is deformed, disassembly can be completed quickly.

[0019] like Figure 1 , 3 As shown in Figure 4, in this embodiment, a positioning groove 7 is formed on the outer circular surface of the support sleeve 4 along its axial direction. The end of the locking pin 2 can pass through the locking sleeve 9 and be locked in the positioning groove 7. The cooperation between the positioning groove 7 and the locking pin 2 can position the movement of the male connector 1 and the female connector 3 during the connection and disconnection process, preventing relative rotation between the male connector 1 and the female connector 3, and ensuring that the male connector 1 and the female connector 3 will not rotate relative to each other after installation. This makes the RF connector more secure and stable during use.

[0020] like Figure 2 , 4 As shown, in this embodiment, the outer circumference of the support sleeve 4 is provided with an mounting ring 5, and the locking sleeve 9 is provided with an annular enlargement 14, which is rotatably fitted onto the mounting ring 5. The annular enlargement 14 is used to install the locking sleeve 9, and the annular enlargement 14 can be interference-fitted with the mounting ring 5 to prevent the locking sleeve 9 from rotating due to its own weight or external shaking when not installed, ensuring that the guide groove 10 and the positioning groove 7 coincide, facilitating the insertion of the locking pin 2.

[0021] The specific usage and beneficial effects of this utility model are as follows: When using this connector, the male connector 1 and female connector 3 can be aligned, and the female connector 3 can be inserted straight into the male connector 1 along the axis of the male connector 1 and female connector 3. When the female connector 3 is inserted into the male connector 1, the locking pin 2 is engaged in the guide groove 10 until the locking pin 2 enters the guide inclined groove 11. The guide inclined groove 11 drives the locking sleeve 9 to rotate as a whole. Then, the male connector 1 and female connector 3 are released. Under the action of the elastic element 6, the locking pin 2 is engaged in the slot 12 to complete the connection between the male connector 1 and female connector 3. When it is necessary to open, the locking sleeve 9 is controlled to rotate in the opposite direction by the opening component so that the locking pin 2 is engaged in the guide groove 10 again, and the male connector 1 and female connector 3 can be separated in a straight line. The entire disassembly and assembly process of this RF connector does not require rotation. Even if the internal metal plate is deformed, the male connector 1 and female connector 3 can be separated, which effectively improves the maintenance efficiency and reduces the maintenance cost.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
