Description

Technical Field

[0001] This utility model relates to the field of radio frequency coaxial connector technology, specifically to a radio frequency coaxial connector connection assembly. Background Technology

[0002] Chinese patent CN219874355U discloses a radio frequency (RF) coaxial connector assembly, comprising a connecting sleeve disposed at the tail end of the RF coaxial connector body. A restraining portion is provided on the side of the connecting sleeve away from the RF coaxial connector body. A fixing cylinder is provided on the outer edge of the connecting sleeve. The fixing cylinder moves on the outer edge of the connecting sleeve, compressing the restraining portion and causing it to converge and conform to the outside of the RF coaxial cable, thus fixing the RF coaxial connector body to the side of the RF coaxial cable. This invention enables the RF coaxial connector body to be quickly connected to the RF coaxial cable through a convergence and convergence method.

[0003] However, the male and female heads of the RF coaxial connector in this patent still require threaded connection, which requires multiple rotation operations. Especially in confined spaces or high-density equipment, repeated twisting is time-consuming and labor-intensive, resulting in low installation efficiency. In addition, the threaded connection is prone to loosening due to vibration or accidental contact, requiring frequent checks on the tightness, which increases maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide an RF coaxial connector assembly that has the advantages of stable connection and convenient installation, thus solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A radio frequency coaxial connector assembly includes a male connector and a female connector. The male connector has a limiting annular groove on its outer side wall. The female connector has multiple mounting grooves evenly distributed circumferentially inside its side wall, communicating with an inner cavity. Limiting beads are installed in the mounting grooves. The female connector also has a sliding annular groove inside its side wall, communicating with the mounting grooves. A pressure ring is slidably disposed in the sliding annular groove. Several springs are provided at the end of the sliding annular groove, and the two ends of the springs are respectively fixedly connected to the end wall of the sliding annular groove and the end face of the pressure ring. The female connector has a circumferentially extending connecting groove on its side wall. A connecting block is disposed through the connecting groove. One end of the connecting block is fixedly connected to the outer wall of the pressure ring, and the other end extends to the outside of the female connector and is fixedly connected to a push-pull ring.

[0007] Preferably, the cross-section of the limiting ring groove is an arc-shaped groove structure adapted to the surface of the limiting bead.

[0008] Preferably, a clearance fit of 0.05-0.1 mm is formed between the outer surface of the pressure ring and the inner wall of the sliding ring groove.

[0009] Preferably, the limiting bead is made of hard alloy material, and the diameter of the limiting bead is 0.1-0.3 mm larger than the inner diameter of the annular constriction at the opening end of the mounting groove.

[0010] Preferably, the number of the limiting beads is not less than four and they are evenly distributed.

[0011] Preferably, the opening end of the mounting groove is provided with an annular closing structure with an inner diameter smaller than that of the limiting bead.

[0012] Preferably, the mounting grooves are evenly distributed along the circumference of the connecting female head, and the mounting grooves communicate with the inner cavity of the connecting female head.

[0013] Preferably, the springs are equidistantly distributed along the circumference of the sliding ring groove.

[0014] Preferably, the outer surface of the pressure ring is coated with a low-friction coefficient coating.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes the locking ring groove of the male connector to engage with the locking bead inside the female connector, combined with the linkage of the sliding ring groove, pressure ring, and spring to form a mechanical interlocking mechanism. This achieves physical locking and unlocking. By leveraging the linkage between the push-pull ring and the connecting block, locking or unlocking can be completed in a single step by pulling the push-pull ring, eliminating the need for tools and simplifying the rotation steps of traditional threaded connections. The spring automatically resets to achieve tool-free locking, and the mechanical interlocking structure prevents accidental loosening. Unlocking is completed in a single step, avoiding the tedious steps of repeated rotation in traditional threaded connections, shortening installation time. The mechanical interlocking structure combined with the automatic spring reset effectively prevents accidental loosening due to vibration or accidental contact, ensuring stable signal transmission.

[0024] 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.

[0025] To address the inconvenience of connector installation in existing technologies, the following technical solution is provided. Please refer to [link / reference needed]. Figure 1-6 ;

[0026] A radio frequency coaxial connector assembly includes a male connector 1 and a female connector 2. A limiting annular groove 3 is formed on the outer side wall of the male connector 1, and the cross-section of the limiting annular groove 3 is designed as an arc-shaped groove.

[0027] The side wall of the connecting female head 2 is provided with an installation groove 5. The installation groove 5 is evenly distributed around the circumference of the connecting female head 2. The installation groove 5 is connected to the inner cavity of the connecting female head 2. The installation groove 5 is provided with a limiting bead 4 that cooperates with the annular groove 3. The number of limiting beads 4 is not less than four and they are evenly distributed.

[0028] A ring-shaped constriction structure is machined at the opening end of the mounting groove 5 so that the inner diameter of the opening is slightly smaller than the diameter of the limiting bead 4, so that the limiting bead 4 will not fall out from the opening of the mounting groove 5.

[0029] The spherical surfaces of the limiting ring groove 3 and the limiting bead 4 fit together naturally, ensuring maximum contact area and reducing contact stress. The limiting bead 4 is made of hard alloy material, such as stainless steel or tungsten carbide, and its surface is polished to reduce friction loss.

[0030] A sliding ring groove 6 is provided inside the side wall of the connecting female head 2. One end of the sliding ring groove 6 is connected to the mounting groove 5. A pressure ring 7 is provided inside the sliding ring groove 6. The pressure ring 7 is slidably connected to the sliding ring groove 6. The outer surface of the pressure ring 7 is coated with a low friction coefficient coating and is in clearance fit with the inner wall of the sliding ring groove 6. The clearance is 0.05-0.1mm to ensure smooth sliding without jamming. The low friction coating reduces the rebound resistance of the spring 8, and the clearance fit prevents the pressure ring 7 from wobbling.

[0031] Several springs 8 are provided at the end of the sliding ring groove 6 away from the mounting groove 5. The springs 8 are evenly distributed around the circumference of the sliding ring groove 6. One end of the spring 8 is fixed to the end side wall of the sliding ring groove 6, and the other end is fixed to the end of the pressure ring 7.

[0032] A connecting groove 9 is also provided around the side wall of the connecting female head 2. A connecting block 10 passes through the connecting groove 9. One end of the connecting block 10 is fixedly connected to the pressure ring 7, and the other end is fixedly connected to the push-pull ring 11 sleeved on the outside of the connecting female head 2.

[0033] Working principle: When installing the male connector 1 and the female connector 2, first pull the push-pull ring 11 away from the male connector 1. This causes the pressure ring 7 to slide in the sliding ring groove 6 via the connecting block 10, compressing the spring 8. At this time, align the female connector 2 with the position of the male connector 1 and insert it through the male connector 1. During insertion, the outer wall of the male connector 1 compresses the limiting bead 4, causing the limiting bead 4 to be completely squeezed into the mounting groove 5. When the limiting bead 4 reaches the limiting ring groove 3, release the push-pull ring 11. At this time, the spring 8 converts its elastic potential energy into kinetic energy. The axial pushing force on the pressure ring 7 causes the end of the pressure ring 7 to squeeze one side of the limiting bead 4 in the mounting groove 5, causing the other side of the limiting bead 4 to pass through the mounting groove 5 and into the limiting ring groove 3. At this time, since the end of the pressure ring 7 is located in the mounting groove 5, it occupies part of the space in the mounting groove 5, preventing the limiting bead 4 from retracting into the mounting groove 5. This creates a mechanical interlock between the female connector 2 and the male connector 1, achieving tool-free locking. When disassembling, the push-pull ring 11 is pulled away from the male connector 1 again, and the female connector 2 is pulled out to achieve quick separation.
