Description

Technical Field

[0001] This utility model relates to the field of near-end machine technology, and in particular to a wiring device for internal use in near-end machines. Background Technology

[0002] The near-end unit is a key device in a wireless communication system, often used in conjunction with the far-end unit. It enables long-distance signal transmission and coverage extension via optical fiber. Primarily installed near the base station, it is responsible for converting the radio frequency (RF) signals output by the base station into optical signals, which are then transmitted to the far-end unit via optical fiber. Simultaneously, it converts the optical signals returned by the far-end unit back into RF signals and sends them back to the base station. This process effectively solves the signal coverage problem in complex terrain or enclosed spaces, ensuring the continuity and stability of communication. The near-end unit has the functions of signal conversion, transmission, and interaction with the base station, making it an indispensable component of modern wireless communication networks.

[0003] In today's rapidly developing communication technology, the rationality and stability of the internal structure of the near-end unit, as an important device in the communication system, directly affects the communication quality. However, the existing wiring methods of the near-end unit are often quite messy, and the wire layout lacks standardization. This not only increases the space occupied inside the equipment, but also easily leads to problems such as wire tangling and wear, which in turn causes faults such as short circuits and signal interference, affecting the normal operation of the equipment and the reliability of communication. At the same time, the messy wiring method also brings great inconvenience to the installation, debugging and maintenance of the equipment. Utility Model Content

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example 1:

[0027] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a wiring device for the internal use of a near-end unit, including a housing 1. A power module 2 and a synchronization module 3 are respectively arranged inside the housing 1, and the power module 2 and the synchronization module 3 are arranged vertically. A high-low pass combiner 4, a frequency shift module 5 and an interface debugging module 6 are respectively arranged inside the housing 1, and the high-low pass combiner 4, the frequency shift module 5 and the interface debugging module 6 are arranged vertically.

[0028] The housing 1 serves as the external protective structure for the entire device, providing installation space for various internal modules and components. It supports and protects internal parts, preventing external interference and damage to the internal circuitry. The power module 2 provides the necessary electrical energy for the entire device, converting externally input electrical energy into voltage and current suitable for each module. The synchronization module 3 synchronizes signals between internal modules, ensuring that different modules operate according to a unified time reference, guaranteeing the overall coordination and stability of the device. The high-low pass combiner 4 separates or combines signals of different frequencies. High-frequency and low-frequency signals can be transmitted separately or combined for transmission to meet the signal processing needs of the device in different operating modes. The frequency shift module 5 changes the frequency of the signal, converting the frequency of the input signal to another frequency for the output signal. This is often used in communication equipment to implement functions such as signal modulation, demodulation, or frequency conversion to adapt to different communication standards and transmission requirements. The interface debugging module 6 provides an interface between the device and external debugging equipment or a computer, facilitating debugging, parameter setting, and fault diagnosis of the device. Through this module, the working status of each module inside the device can be monitored in real time, and relevant parameters can be adjusted to ensure the normal operation of the device.

[0029] The casing 1 is equipped with a cable assembly 7. The cable assembly 7 includes two sets of first wires 71 electrically connected to the electrical output terminal of the power module 2. The ends of the two sets of first wires 71 away from the power module 2 are electrically connected to the electrical input terminals of the synchronization module 3 and the frequency shift module 5, respectively. The electrical output terminal of the high-low pass combiner 4 is electrically connected to a second wire 72. The end of the second wire 72 away from the high-low pass combiner 4 is electrically connected to the electrical input terminal of the frequency shift module 5. The electrical output terminal of the interface debugging module 6 is electrically connected to three sets of third wires 73. The ends of the third wires 73 away from the interface debugging module 6 are electrically connected to the electrical input terminals of the synchronization module 3 and the frequency shift module 5, respectively.

[0030] Since the ends of the first wires 71, which are electrically connected to the electrical output terminals of the power module 2, are electrically connected to the electrical input terminals of the synchronization module 3 and the frequency shift module 5 respectively, the first wires 71 can transmit the power of the power module 2 to the synchronization module 3 and the frequency shift module 5 respectively, thus enabling the power module 2 to supply power to these two modules. Since one end of the second wire 72 is electrically connected to the electrical output terminal of the high-low pass combiner 4, and the end of the second wire 72, which is far from the high-low pass combiner 4, is electrically connected to the electrical input terminal of the frequency shift module 5, the second wire 72 is used to transmit the signal processed by the high-low pass combiner 4 to the frequency shift module 5, thus enabling the signal to be transmitted between the two modules. Since the end of the third wire 73, which is electrically connected to the electrical output terminal of the interface debugging module 6, is far from the interface debugging module 6, is electrically connected to the electrical input terminals of the synchronization module 3 and the frequency shift module 5 respectively, the third wire 73 can transmit the signal of the interface debugging module 6 to the synchronization module 3 and the frequency shift module 5 respectively, thus enabling the control and parameter adjustment of these two modules during the debugging process.

[0031] Example 2:

[0032] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0033] Specifically, a first connector 8 is provided on one side of the high-low pass combiner 4, and a second connector 9 is provided on one side of the frequency shift module 5. The first connector 8 and the second connector 9 are connected by a second wire 72.

[0034] The first connector 8 is located on one side of the high-low pass combiner 4, and the second connector 9 is located on one side of the frequency shift module 5. The two are connected by the second wire 72, which facilitates the quick and reliable connection of the second wire 72 with the high-low pass combiner 4 and the frequency shift module 5, and makes it convenient for the installation, maintenance and replacement of the equipment.

[0035] Specifically, the inner wall of the housing 1 is provided with a slot 10, and the slot 10 is a ring design. The inner wall of the housing 1 is provided with several sets of threaded holes 11.

[0036] The ring-shaped slot 10 can be used to install some components that need to be fixed to the inner wall of the housing 1, serving a positioning and fixing function to ensure that these components will not shake or shift during equipment operation. The threaded hole 11 provides a position for threaded connection with other components or equipment, making it convenient to fix the housing 1 to other structures, ensuring the overall stability of the equipment and the firmness of the installation.

[0037] Specifically, the inner wall of the high-low pass combiner 4 is provided with several sets of first mounting holes 12, and the inner wall of the frequency shift module 5 is provided with several sets of second mounting holes 13.

[0038] The first mounting hole 12 is opened on the inner wall of the high-low pass combiner 4 and is used to fix the high-low pass combiner 4 inside the housing 1. Fasteners such as bolts pass through the first mounting hole 12 and are connected to the housing 1 to ensure the stability of the high-low pass combiner 4 during operation. The second mounting hole 13 is opened on the inner wall of the frequency shift module 5 and has a similar function to the first mounting hole 12. It is used to fix the frequency shift module 5 inside the housing 1 and ensure that the frequency shift module 5 is firmly installed.

[0039] Example 3:

[0040] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0041] Specifically, the high-low pass combiner 4 has two sets of first interfaces 14 on one side, and the end of the first interface 14 away from the high-low pass combiner 4 passes through the inner wall of the housing 1 and extends to the outer side of the housing 1. The frequency shift module 5 has a second interface 15 on one side, and the end of the second interface 15 away from the frequency shift module 5 passes through the inner wall of the housing 1 and extends to the outer side of the housing 1.

[0042] The first interface 14 and the second interface 15 serve as interfaces for signal transmission between the high-low pass combiner 4 and the frequency shift module 5 and external devices. Signals can be input to or output to the devices through these interfaces, enabling the devices to connect and communicate with external systems and meet the signal interaction needs of the devices in different application scenarios.

[0043] Specifically, the inner wall of the housing 1 is fixed with several sets of support rods 16, and the inner wall of the interface debugging module 6 is provided with several sets of connection holes 17, and the positions of the connection holes 17 correspond to the positions of the support rods 16.

[0044] The support rod 16 can support the interface debugging module 6. By cooperating with the connection hole 17 on the inner wall of the interface debugging module 6, the interface debugging module 6 is fixed in a specific position inside the housing 1, ensuring the installation stability and reliability of the interface debugging module 6.

[0045] Specifically, an interface debugging module 6 has a debugging interface 18 on one side, and the end of the debugging interface 18 away from the interface debugging module 6 penetrates the inner wall of the housing 1 and extends to the outer side of the housing 1. Several sets of heat dissipation fins 19 are provided on the outer side of the housing 1.

[0046] The debugging interface 18 provides technicians with an interface to interact with the interface debugging module 6. Through this interface, debugging equipment can be connected to perform debugging, testing, and parameter setting operations on the equipment, which facilitates technicians to maintain the equipment and troubleshoot faults. The heat dissipation fins 19 increase the heat dissipation area of ​​the casing 1 and improve the heat dissipation efficiency of the equipment. During the operation of the equipment, the internal components will generate heat. The heat dissipation fins 19 can quickly dissipate the heat to the surrounding environment to prevent the equipment from being affected or damaged due to overheating, and ensure that the equipment operates stably at a suitable temperature.

[0047] Working Principle: When the near-end unit is in the cabling operation, the power module 2 serves as the energy source for the entire near-end unit. Through two sets of first wires 71 in the cabling assembly 7, it supplies power to the synchronization module 3 and the frequency shift module 5 respectively, ensuring stable power distribution so that each module can obtain the necessary power for normal operation. The layout of the first wires 71 considers space utilization and minimizing electromagnetic interference, ensuring reliable power supply. The high-low pass combiner 4 is responsible for frequency splitting or combining of signals. Its output is connected to the frequency shift module 5 through the second wire 72 to realize frequency band conversion or processing of signals. The frequency shift module 5 shifts or modulates the received signal to meet specific communication requirements. Simultaneously, the interface debugging module 6 is connected to the synchronization module 3 and the frequency shift module 5 through three sets of third wires 73 for parameter configuration, status monitoring, and debugging, ensuring... The stable operation of the entire system is ensured by the synchronization module 3, which is responsible for synchronizing all modules to ensure that they work in a unified timing sequence, thereby improving the overall performance of the system. The high-low pass combiner 4 and the frequency shift module 5 are directly connected through the first connector 8 and the second connector 9, which reduces signal transmission loss and improves transmission efficiency. In addition, the first interface 14 and the second interface 15 on the housing 1 provide channels for external signal input / output, facilitating system integration and expansion. The slots 10 and threaded holes 11 on the inner wall of the housing 1 are used to fix each module and ensure their stable position within the housing 1. The support rod 16 cooperates with the connection hole 17 on the interface debugging module 6 to provide additional structural support and enhance the stability of the system. At the same time, the heat dissipation fins 19 on the outer side of the housing 1 accelerate heat dissipation, prevent the modules from overheating, and ensure the long-term stable operation of the system.
