Description

Technical Field

[0001] The utility model relates to the technical field of radio frequency lines, in particular to a radio frequency connecting line. Background Art

[0002] RF cables are electronic components used to transmit RF signals. Typically, RF cables are used to connect RF signals within a device to an antenna, test equipment, or other equipment. There are many types of these connectors, including SMA, BNC, TNC, N-type, F-type, etc. They play an important role in applications such as wireless communications, broadcast television, radar, and test and measurement.

[0003] When current RF cables are connected to different devices, different types of RF cables need to be used according to different device models, so their applicability is relatively small. In addition, the wiring position generally needs to be hidden during installation, so they will often come into contact with the gaps between devices or the corners of walls. During long-term use and connection, their surface is easily worn, causing the internal lines to be exposed, affecting signal transmission. Utility Model Content

[0022] Example

[0023] Please refer to Figure 1-Figure 3 The utility model provides a radio frequency connecting line, including a radio frequency cable 1, a cable network management 2, a radio frequency connector 3, a quick-release structure 4, and a radio frequency mounting head 5.

[0024] Furthermore, a cable network tube 2 is connected to the outer jacket of the radio frequency cable 1 , and the cable network tube 2 includes a metal network tube 21 and a retaining ring 22 .

[0025] Specifically, the metal mesh tube 21 is a cylindrical metal mesh structure with a mesh shape of diamond or circle. Because metal material is easy to conduct heat, the overall stability of the metal mesh tube 21 is maintained while reducing the shielding area of ​​the RF cable 1 therein, thereby increasing heat dissipation and ventilation.

[0026] Both ends of the metal mesh tube 21 are fixedly connected to the retaining ring 22, which is fixedly installed on the outside of the RF cable 1. The wall thickness of the metal mesh tube 21 is less than 2 mm, and there is a spacing space between it and the RF cable 1, so that the surfaces of the two do not touch each other.

[0027] Preferably, the flexibility of the metal mesh tube 21 is increased by a thinner thickness, so that the metal mesh tube 21 can bend along with the RF cable 1 when it is bent while protecting the internal RF cable 1 , without affecting the normal use of the RF cable 1 .

[0028] Because the RF cable 1 is generally installed at the corner of the equipment or the wall, its surface will contact and rub against the corners of various equipment, or be squeezed between equipment, causing surface wear. Therefore, through the support of the mesh structure of the metal mesh tube 21 itself, the RF cable 1 is separated from various easily worn positions by the external metal mesh tube 21 and does not contact them, thereby ensuring a longer service life of the cable.

[0029] The spacing space between the metal mesh tube 21 and the radio frequency cable 1 is an elastic space for the metal mesh tube 21 to be elastically deformed. When the metal mesh tube 21 is squeezed by external equipment, it will undergo corresponding elastic deformation to protect the radio frequency cable 1 from being squeezed.

[0030] Furthermore, an RF connector 3 is fixedly installed at one end of the RF cable 1, and the two are an integrated structure. A quick-release structure 4 is connected to the outer sleeve of the RF connector 3, and the quick-release structure 4 is divided into a fixed end and a disassembly end. The fixed end is fixedly connected to the RF connector 3 and does not detach, while the disassembly end can be rotated relative to the fixed end for quick disassembly, and an RF mounting head 5 is fixedly provided on the disassembly end.

[0031] The RF connector 3 is matched and connected with the signal receiving hole of the external device, and the RF mounting head 5 outside the RF connector 3 can lock the RF connector 3 with the external device. The RF connector 3 is generally of a fixed size, but in order to lock and match with different models of equipment, the external RF mounting head 5 needs to change different mounting hole diameters to adapt.

[0032] Preferably, by setting a quick-release structure 4 on the outside of the RF connector 3 and installing the RF mounting head 5 on the quick-release structure 4, when connecting and matching with different models of equipment, the RF mounting head 5 with different mounting apertures can be quickly replaced for quick matching without replacing the entire RF connecting line, thereby increasing its applicability.

[0033] In some feasible embodiments, the quick-release structure 4 includes a fixed housing 41 , a threaded tube 42 , and a threaded sleeve 43 .

[0034] Specifically, the fixed shell 41 is fixedly sleeved at the connection between the RF connector 3 and the RF cable 1 to protect the connection. One end of the fixed shell 41 close to the RF connector is fixedly connected to a threaded tube 42, and a threaded sleeve 43 is sleeved on the threaded tube 42. The two are sleeved by threaded matching, and the threaded sleeve 43 is connected to the RF mounting head 5. When a different RF mounting head 5 needs to be replaced, the threaded sleeve 43 can be quickly removed for replacement by rotating it.

[0035] In this embodiment, the RF connector 3 is coaxially arranged in the RF mounting head 5. The RF connector 3 is used to be plugged into a terminal of an external device, and the RF mounting head 5 is sleeved with a terminal housing.

[0036] The threaded tube 42 is a fixed end of the quick-release structure 4 and cannot be moved, while the threaded sleeve 43 is a disassembly end of the quick-release structure 4 and can be disassembled by threading.

[0037] In some feasible embodiments, the installation part in the RF installation head 5 can rotate automatically to improve the installation efficiency of the staff. The RF installation head 5 includes a connecting pipe 51, a mounting pipe head 52, an annular stopper 53, and a nut 54.

[0038] Specifically, one end of the connecting tube 51 is fixedly connected to the threaded sleeve 43, and the two are coaxially arranged. The outer diameter of the connecting tube 51 is smaller than the outer diameter of the threaded sleeve 43, so that a step is formed on the outside of the two. An annular stopper 53 is fixed on the outer diameter of the other end of the connecting tube 51 away from the threaded sleeve 43. The annular stopper 53 protrudes from the outer wall of the connecting tube 51, so that a step is also formed between it and the connecting tube 51, and the steps formed at both ends of the connecting tube 51 will form a cylindrical notch on the outer diameter of the connecting tube 51.

[0039] A mounting tube head 52 is rotatably connected to the cylindrical notch, and the inner wall of the mounting tube head 52 fits with the groove surface of the cylindrical notch. An annular groove is provided at a position corresponding to the inner wall of the mounting tube head 52 and the annular stopper 53 at one end of the cylindrical notch, which is matched and snap-fitted with the annular stopper 53; so that the mounting tube head 52 can be rotated freely on the outer diameter of the connecting tube 51, and the annular stopper 53 can prevent the mounting tube head 52 and the connecting tube 51 from being separated.

[0040] The outer wall of the mounting tube head 52 is provided with a thread, which is coaxially threadedly connected in the terminal housing and connected and locked with the terminal housing of the external device. The outer wall of the mounting tube head 52 is threadedly matched with a nut 54 .

[0041] When the mounting tube head 52 is threadedly locked with the terminal housing, the nut 54 can be rotated through the thread outside the mounting tube head 52, move along the mounting tube head 52 to be located outside the terminal housing, and clamp the terminal housing by friction. Its movement can adjust the tightness of the locking part.

[0042] Preferably, the mounting tube head 52 in the RF mounting head 5 can rotate by itself. When the staff connects the cable connecting line to the external device, they can only rotate the mounting tube head 52 without rotating the RF cable 1, ensuring that the RF cable 1 will not be tangled due to being driven to rotate.

[0043] Moreover, the freely rotatable mounting tube head 52 can prevent interference in the threaded connection between the RF mounting head 5 and the quick-release structure 4, and the rotation of the mounting portion of the RF mounting head 5 will not cause the disassembly end of the quick-release structure 4 to rotate and separate.
