Description

Technical Field

[0001] This utility model relates to the field of adapter technology, and more specifically to an radio frequency coaxial cable adapter. Background Technology

[0002] A cable adapter is an intermediate device that enables quick connection between two cables or repairs broken cable assemblies. Coaxial cables can be used for the transmission of analog and digital signals and are suitable for a wide variety of applications, most notably television broadcasting, long-distance telephone transmission, short-distance connections between computer systems, and local area networks (LANs). In practical construction, it has been found that sometimes coaxial cables of different thicknesses need to be connected, requiring the use of coaxial cable adapters. However, such connectors are currently very rare on the market, and installers typically solve the problem by using multiple adapters, which is inefficient and costly.

[0003] Therefore, developing a simple and efficient radio frequency coaxial cable adapter is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the present invention provides an RF coaxial cable adapter that is simple to operate and has high installation efficiency.

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

[0006] A radio frequency coaxial cable adapter, characterized in that it comprises:

[0007] A housing, with cables connected to both ends of the housing;

[0008] An inner insulator is disposed within the housing, and a transition cavity is formed inside the inner insulator. Both ends of the inner insulator are provided with through holes for the inner conductor of the cable to pass through.

[0009] An adapter plate is disposed within the adapter cavity, and symmetrically arranged elastic clips are provided on both sides of the adapter plate; each elastic clip includes multiple clips, which are arranged in a ring, with one end of each clip connected to the adapter plate, the middle portion converging towards the center, and the other end forming an outwardly expanding funnel shape.

[0010] The beneficial effect of adopting the above technical solution is that the flared clamp design of the elastic clamp enables rapid adaptive clamping of cables of different thicknesses, simplifies operation, and improves installation efficiency.

[0011] Preferably, the housing comprises: a first housing and a second housing, the inner insulator being disposed within the first housing, and the second housing being threadedly connected to the first housing. The split-type housing facilitates disassembly and maintenance while enhancing structural sealing and mechanical strength.

[0012] Preferably, the interior of the first housing has a step, and the end of the inner insulator abuts against the step. The inner insulator is positioned by the step to ensure precise alignment between the adapter plate and the inner conductor of the cable, avoiding signal loss due to shaking.

[0013] Preferably, an end cap is provided at one end of the inner insulator near the second housing, and the open end of the inner insulator is in sealed contact with the end cap.

[0014] Preferably, a pressure ring is provided at one end of the second housing near the end cap, and the pressure ring presses the end cap tightly. The pressure ring presses the end cap tightly, further enhancing the sealing stability of the end cap.

[0015] Preferably, the first and second housings have elastic pressure plates at one end where they press against the cable, and multiple elastic pressure plates are arranged along the circumference of the first or second housing. This circumferential distribution of the elastic pressure plates ensures uniform stress on the cable sheath, preventing localized damage, and also allows for compatibility with cables of different outer diameters.

[0016] Preferably, the elastic pressure plate is inclined outwards towards the first or second housing, and a pressure block is provided on the side of the elastic pressure plate closest to the cable. The pressure block cooperates with the elastic pressure plate to increase the contact area, improve the reliability of cable fixation, and reduce the risk of loosening due to vibration.

[0017] Preferably, nuts are connected to the outside of both the first housing and the second housing. The nuts move on the surface of the first housing or the second housing, causing multiple elastic pressure plates to gather and compress the cable.

[0018] Preferably, sealing rings are provided at the contact points between the end cap and the inner insulator, the contact points between the cable and the pressure ring, and the contact points between the cable and the step.

[0019] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a radio frequency coaxial cable adapter, the advantages of which are:

[0020] (1) In this utility model, the elastic clamp adaptively clamps the cable, which can adapt to cables of different diameters, making it easy to operate and applicable to a wider range of applications;

[0021] (2) The cable can be tightened by turning the nut, which ensures a more stable connection between the cable and the shell and makes it less prone to loosening; and the cable connection can be completed quickly, significantly shortening the construction time. Attached Figure Description

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.

[0040] This utility model discloses a radio frequency coaxial cable adapter, comprising:

[0041] Housing 1, with cables 2 connected to both ends of housing 1;

[0042] The inner insulator 3 is disposed inside the housing 1, and the interior of the inner insulator 3 forms a transition cavity 31. Both ends of the inner insulator 3 are provided with wire holes 32 for the inner conductor of the cable 2 to pass through.

[0043] An adapter plate 4 is disposed within an adapter cavity 31. Symmetrically arranged elastic clips 5 are provided on both sides of the adapter plate 4. Each elastic clip 5 includes multiple clips 51 arranged in a ring. One end of each clip 51 is connected to the adapter plate 4, the middle portion converges towards the center, and the other end forms an outwardly expanding funnel shape. The cable 2 enters the elastic clip 5 through the through-hole 32 and is clamped by the central convergence of the multiple clips 51. The elastic clip 5 allows for the transfer of cables 2 of different thicknesses, providing greater adaptability.

[0044] To further optimize the above technical solution, a support rod 41 is provided on the outer circumference of the adapter plate 4. The support rod 41 is connected to the inner wall of the inner insulator 3, which can fix the position of the adapter plate 4 and determine the accuracy of the connection between the cable 2 and the elastic clip 5.

[0045] To further optimize the above technical solution, the housing 1 includes: a first housing 11 and a second housing 12, with the inner insulator 3 placed inside the first housing 11, and the second housing 12 threadedly connected to the first housing 11. The threaded connection between the first housing 11 and the second housing 12 allows for a tighter connection between the inner insulator 3 and the end cap 33, resulting in a better sealing effect.

[0046] To further optimize the above technical solution, a step 13 is provided inside the first housing 11, and the end of the inner insulator 3 abuts against the step 13.

[0047] To further optimize the above technical solution, an end cap 33 is provided at one end of the inner insulator 3 near the second housing 12, and the open end of the inner insulator 3 is in sealed contact with the end cap 33. The separate arrangement of the end cap 33 and the inner insulator 3 facilitates the placement of the elastic clip 5 inside the inner insulator 3.

[0048] To further optimize the above technical solution, a pressure ring 14 is provided at one end of the second housing 12 near the end cover 33, and the pressure ring 14 presses the end cover 33 tightly.

[0049] To further optimize the above technical solution, the first housing 11 and the second housing 12 are provided with elastic pressure plates 6 at one end of the cable 2, and multiple elastic pressure plates 6 are arranged along the circumferential direction of the first housing 11 or the second housing 12.

[0050] To further optimize the above technical solution, the elastic pressure plate 6 is inclined outward towards the first housing 11 or the second housing 12, and a pressure block 7 is provided on the side of the elastic pressure plate 6 closest to the cable 2. For example... Figure 4 As shown, the side of the pressure block 7 connected to the elastic pressure plate 6 is inclined, and the side of the pressure block 7 in contact with the cable 2 is parallel to the axis of the cable 2. When the nut 8 tightens the elastic pressure plate 6, multiple elastic pressure plates 6 converge towards the center, and the cable is tightened by the pressure block 7. The pressure area of ​​the pressure block 7 on the cable 2 is large, which can improve the stability of the cable 2 after connection. The first housing 11, the second housing 12, the connection between the elastic pressure plate 6 and the nut are all provided with threads (not shown in the figure).

[0051] To further optimize the above technical solution, nuts 8 are connected to the outside of both the first housing 11 and the second housing 12. The nuts 8 move on the surface of the first housing 11 or the second housing 12 to drive multiple elastic pressure plates 6 to gather and compress the cable 2.

[0052] To further optimize the above technical solution, sealing rings 9 are provided at the contact points between the end cap 33 and the inner insulator 3, the contact points between the cable 2 and the pressure ring 14, and the contact points between the cable 2 and the step 13.
