Abstract
Description
Technical Field
[0001] This utility model relates to the field of connecting cable technology, specifically to coaxial radio frequency connecting cables. Background Technology
[0002] Radio frequency (RF) coaxial cable is a type of cable used for transmitting radio frequency (RF) signals. It consists of a center conductor made of a metal such as copper or aluminum, and an outer insulation layer made of polyurethane (PVC) or other insulating materials. RF coaxial cable is characterized by its excellent RF signal transmission performance, high transmission efficiency, low signal loss, strong anti-interference capability, and long transmission distance, meeting the needs of most cable transmission applications.
[0003] Existing radio frequency coaxial cables often require multiple cables to be used due to distance limitations. However, when these cables are connected by connectors, they are prone to detachment over time. Once detached, they require timely inspection and maintenance, so improvements are needed. Utility Model Content
[0004] The purpose of this invention is to provide a coaxial radio frequency connection cable to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a coaxial radio frequency connection cable, including an outer sheath, a connector, a limiting frame, and a clamping bracket.
[0006] A conductor is provided inside the outer sheath;
[0007] A connector is fitted onto the outer sheath;
[0008] The connector is equipped with mounting nut one and mounting nut two.
[0009] The outer sheath is provided with a limiting frame and a clamping bracket;
[0010] The limiting frame is equipped with a bearing, and the bearing is equipped with a rotating shaft.
[0011] Preferably, an inner insulation layer is installed on the conductor, a braided layer is installed on the inner insulation layer, and the braided layer is installed inside the outer sheath. The coaxial radio frequency connection cable is formed by installing the inner insulation layer and the braided layer on the conductor and then installing it inside the outer sheath.
[0012] Preferably, there are four mounting nuts (first and second), and the four mounting nuts (first and second) are arranged in a circular array relative to the center of the connecting member. By having four mounting nuts (first and second), the two sets of screws (first and second) can be installed separately.
[0013] Preferably, a screw rod is threadedly installed inside the mounting nut, and the screw rod limits the positioning frame. As the screw rod moves helically within the mounting nut, it can compress and limit the positioning frame.
[0014] Preferably, a limiting rod is welded onto the limiting frame, and the limiting rod is sleeved inside the connecting member. By sleeved the limiting rod inside the connecting member, the limiting frame can be installed inside the connecting member.
[0015] Preferably, a screw rod is threadedly installed inside the mounting nut, and the screw rod limits the position of the clamping frame. The screw rod can compress and limit the clamping frame as it rotates helically within the mounting nut.
[0016] Preferably, a second limiting rod is welded to the side end face of the clamping frame, and the second limiting rod is sleeved inside the connecting member. By sleeved inside the connecting member, the clamping frame can be installed inside the connecting member.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] 1. This utility model, by incorporating a connector, allows for the use of a coaxial radio frequency connection cable. The cable consists of an inner insulation layer and a braided layer mounted on the conductor, which are then installed within an outer sheath. During cable use, the connector is fitted onto the outer sheath. After fitting, the connector can be used to install the connection between the two cables. Next, the operator contacts the cable via a rotating shaft, which is mounted within a bearing for rotation. As the shaft rotates, it moves the connector along the cable until it reaches the connection point. Upon reaching the connection position, the operator can use a screw within a mounting nut to apply pressure and restraint to the limiting frame, clamping it at the cable connection point and achieving initial connection restraint, thus meeting the cable connection requirements.
[0019] 2. This utility model, by setting up a clamping frame, allows for cable connection after the operator completes the connection operation and applies initial compression and limitation to the connection point using the limiting frame. Next, the operator can move the cable by rotating the screw two within the mounting nut two. During this process, the screw two applies compression and limiting force to the clamping frame. The compressed clamping frame tightly holds the two cables, thus enabling the two cables to be reconnected and limited by both the clamping frame and the limiting frame. This connection method effectively avoids the loosening and detachment problems that may occur when relying solely on connectors, thereby greatly reducing the inconvenience caused by later inspection and maintenance work.

[0026] 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.
[0027] Example 1
[0028] like Figures 1-5 As shown, the coaxial radio frequency connection cable proposed in this utility model includes an outer sheath 1, a connector 5, a limiting frame 14, and a clamping frame 15.
[0029] A conductor 4 is installed inside the outer sheath 1;
[0030] The outer sheath 1 is fitted with a connector 5;
[0031] The connector 5 is equipped with mounting nut 1 6 and mounting nut 2 11;
[0032] The outer sheath 1 is provided with a limiting frame 14 and a clamping frame 15;
[0033] A bearing 12 is installed inside the limiting frame 14, and a rotating shaft 13 is installed inside the bearing 12.
[0034] An inner insulation layer 3 is installed on the conductor 4, and a braided layer 2 is installed on the inner insulation layer 3. The braided layer 2 is installed inside the outer sheath 1. The inner insulation layer 3 and the braided layer 2 are installed on the conductor 4 and then installed inside the outer sheath 1 to form a coaxial radio frequency connection cable.
[0035] There are four mounting nuts 6 and 11 in total, and the four mounting nuts 6 and 11 are arranged in a circular array relative to the center of the connector 5. By having four mounting nuts 6 and 11, the two sets of screws 7 and 10 can be installed respectively.
[0036] A screw rod 7 is threadedly installed inside the mounting nut 6, and the screw rod 7 limits the limiting frame 14. When the screw rod 7 moves spirally inside the mounting nut 6, it can squeeze and limit the limiting frame 14.
[0037] A limiting rod 8 is welded onto the limiting frame 14, and the limiting rod 8 is sleeved inside the connecting piece 5. By the limiting rod 8 being sleeved inside the connecting piece 5, the limiting frame 14 can be installed inside the connecting piece 5.
[0038] Based on Embodiment 1: A coaxial radio frequency connection cable is formed by installing an inner insulation layer 3 and a braided layer 2 on the conductor 4 and then installing it inside the outer sheath 1. When using the cable, the operator can put the connector 5 on the outer sheath 1. After the connector is put on, the operator can install the connection between the two cables using a connector. The operator contacts the cable through the rotating shaft 13 and rotates the shaft 13, which is installed in the bearing 12. When the rotating shaft 13 rotates, it can drive the connector 5 to move on the cable and move to the cable connection point. After reaching the connection point, the operator can squeeze and limit the limiting frame 14 by spiraling the screw 7 inside the mounting nut 6. This causes the limiting frame 14 to clamp the cable connection point for initial connection and limitation, thereby satisfying the connection and use of the cable.
[0039] Example 2
[0040] like Figures 1-5 As shown, the coaxial radio frequency connection cable proposed in this utility model, compared with Embodiment 1, further includes: an outer sheath 1, a connector 5, a limiting frame 14, and a clamping frame 15.
[0041] A conductor 4 is installed inside the outer sheath 1;
[0042] The outer sheath 1 is fitted with a connector 5;
[0043] The connector 5 is equipped with mounting nut 1 6 and mounting nut 2 11;
[0044] The outer sheath 1 is provided with a limiting frame 14 and a clamping frame 15;
[0045] A bearing 12 is installed inside the limiting frame 14, and a rotating shaft 13 is installed inside the bearing 12.
[0046] A screw rod 10 is threadedly installed inside the mounting nut 2 11, and the screw rod 10 limits the clamping frame 15. When the screw rod 10 moves spirally inside the mounting nut 2 11, it can squeeze and limit the clamping frame 15.
[0047] A limiting rod 2 9 is welded to the side end face of the clamping frame 15, and the limiting rod 2 9 is sleeved in the connecting piece 5. By the limiting rod 2 9 being sleeved in the connecting piece 5, the clamping frame 15 can be installed in the connecting piece 5.
[0048] Based on Embodiment 2: After the personnel connect the cables and use the limiting frame 14 to initially squeeze and limit the connection, the personnel can squeeze and limit the clamping frame 15 by rotating the screw 10 in the mounting nut 11. This squeezes the clamping frame 15 and clamps it onto the two cables, so that the two cables are reconnected and limited by the clamping frame 15 and the limiting frame 14 respectively. This avoids the loosening and falling off caused by directly using connectors, thereby reducing the inconvenience caused by later inspection and maintenance.
[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
