Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a radio frequency coaxial connector. Background Technology

[0002] RF coaxial connectors are electromechanical products used in radio frequency and microwave systems to connect coaxial cables to devices. They ensure signal stability and low loss during transmission through insulation between the center and outer conductors. RF coaxial connectors are widely used in communications, radar, aerospace, and military fields, and are indispensable key components in signal transmission systems.

[0003] In existing technologies, the housing and cable of traditional connectors are mostly fixed connection structures. During installation, the installation angle of the connector must be strictly aligned. If there is a deviation between the angle between the cable and the device interface, it is often necessary to adjust the cable routing or use an adapter. This not only increases the installation steps and time costs, but may also increase signal transmission loss due to forced bending of the cable. Therefore, we propose an RF coaxial connector to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a radio frequency coaxial connector.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A radio frequency coaxial connector includes a housing, a sheath at the bottom of the housing, and connectors fixedly connected to both the sheath and the bottom of the housing. An insulating sleeve is fixedly connected to the bottom of one of the connectors. A contact assembly is provided inside the housing. A rubber sleeve is fixedly connected to the bottom of the insulating sleeve, and a metal sleeve is fixedly connected to the bottom of the rubber sleeve. Two shafts are fixedly connected to the outer wall of the insulating sleeve. Connecting strips are fitted onto the outer walls of both shafts. One end of each connecting strip is fixedly connected to the outer wall of the metal sleeve. Locking caps are threaded onto the outer walls of both shafts.

[0007] Preferably, the contact assembly includes a contact element, and the outer walls of both connecting seats are provided with sliding holes. The inner walls of the sliding holes are slidably connected to the outer walls of the contact elements. The outer walls of the contact elements are fixedly connected to the inner walls of the housing. The bottom of the contact element is located inside the insulating sleeve.

[0008] Preferably, a sealing sleeve is fixedly connected to the top of the connecting seat, and the inner wall of the sealing sleeve is fixedly connected to the outer wall of the housing.

[0009] Preferably, the outer walls of both connecting seats are provided with mounting holes, and the outer walls of the contact members are provided with slots.

[0010] Preferably, the outer wall of the sheath has two circular holes, and the inner walls of the two circular holes are rotatably connected to the outer walls of the two shafts respectively.

[0011] Preferably, the outer wall of the housing is provided with an annular mating groove.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution allows the cable and connecting strip to flexibly adjust the angle between the cable and the housing by rotating the metal sleeve around the shaft, adapting to the angle requirements of different installation scenarios. This eliminates the need for additional cable routing adjustments or the use of adapters, reducing installation time and costs, and avoiding signal transmission loss caused by forcibly bending the cable. After adjusting to the appropriate angle, the connecting strip can be securely fixed by rotating the locking cap and squeezing the protective sleeve, ensuring reliable locking in different orientations such as L-shape and tilt, while the rubber sleeve provides elastic protection for the connection position.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Depend on Figures 1-4 As shown, an RF coaxial connector is disclosed, comprising a housing 1, a sheath 6 at the bottom of the housing 1, and a connector 2 fixedly connected to both the sheath 6 and the bottom of the housing 1. A sealing sleeve 3 is fixedly connected to the top of the connector 2, and the inner wall of the sealing sleeve 3 is fixedly connected to the outer wall of the housing 1. An insulating sleeve 4 is fixedly connected to the bottom of one of the connectors 2. The insulating sleeve 4 provides insulation protection for the connection between the contact 7 and the cable to prevent short circuits. On the other hand, its bottom is fixedly connected to a rubber sleeve 8 to provide basic support for the rotation of the metal sleeve 9.

[0022] Both connectors 2 have mounting holes 5 on their outer walls. Through the mounting holes 5, the two connectors 2 can be mated using existing bolts and nuts, ensuring the accurate positioning of the connector during installation.

[0023] A rubber sleeve 8 is fixedly connected to the bottom of the insulating sleeve 4. The rubber sleeve 8 uses its own elastic properties to protect the connection position between the two. A metal sleeve 9 is fixedly connected to the bottom of the rubber sleeve 8. Two shafts 10 are fixedly connected to the outer wall of the insulating sleeve 4. Two round holes are opened on the outer wall of the sheath 6. The inner walls of the two round holes are rotatably connected to the outer walls of the two shafts 10 respectively. A connecting strip 11 is fitted on the outer wall of each of the two shafts 10. One end of each connecting strip 11 is fixedly connected to the outer wall of the metal sleeve 9. The two connecting strips 11 are symmetrically arranged, which enhances the balance and structural stability of the metal sleeve 9 when it rotates.

[0024] Both shafts 10 have locking caps 12 threaded on their outer walls. By rotating the locking caps 12 to press the outer wall of the sheath 6, the connecting strip 11 can be firmly fixed to prevent angular displacement. The outer wall of the housing 1 has an annular mating groove 14.

[0025] The housing 1 has a contact assembly inside, which includes a contact 7. The contact 7 is the core component for signal transmission. The slot 13 on its outer wall facilitates cable insertion and fixation by crimping or soldering, ensuring a reliable connection between the cable and the contact 7, reducing contact resistance, and ensuring efficient transmission of radio frequency signals. The outer wall of the contact 7 has a slot 13. The outer walls of the two connecting seats 2 have sliding holes. The inner wall of the sliding hole is slidably connected to the outer wall of the contact 7. The outer wall of the contact 7 is fixedly connected to the inner wall of the housing 1. The bottom of the contact 7 is located inside the insulating sleeve 4.

[0026] Working principle: In use, align the two connecting seats 2 with each other, first pass the insulating sleeve 4 through the cable, then insert one end of the cable into the contact 7 through the slot 13 on the contact 7, and fix one end of the cable in the contact 7 by crimping or soldering. Then put the insulating sleeve 4 on the contact 7 and the cable, and connect the two connecting seats 2 through multiple mounting holes 5 and existing bolts. Adjust the angle between the cable and the housing 1 according to the required angle, rotate the metal sleeve 9 to drive the cable inside it to rotate. At this time, the connecting strip 11 rotates around the shaft 10. After rotating to the appropriate angle, rotate the two locking caps 12 to press against the outer wall of the sheath 6 to fix the position of the two connecting strips 11, so that the whole is in an L-shape or inclined shape. The rubber sleeve 8 protects the connection position between the sheath 6 and the metal sleeve 9, and has specific elasticity.
