[0002] In the development of modern communication and network technology, the integrated wiring system plays a vital role. With the accelerated advancement of informatization and intelligence, the integration, efficiency and convenience of the wiring system have become an inevitable trend in the development of the industry. At present, the field of technical construction of the integrated wiring system usually adopts the method of on-site wiring. This solution is time-consuming and requires high technical capabilities of workers. It is highly dependent on the technical level of workers, which increases the uncertainty and risk in the installation process to a certain extent. At the same time, in scenarios with strict requirements on installation time and disconnection time, traditional methods are obviously difficult to meet the needs.

[0003] At present, the existing pre-terminated components are to install several independent network modules pre-installed on the twisted pair cable in the module box, and then install the module box on the patch panel. This installation method solves the problem of on-site wiring to a certain extent, but its volume is too large, and the existing module box and patch panel are connected by threads, and this installation method is cumbersome. Summary of the invention

[0012] Preferably, the wiring rack includes a panel, a fixing plate is fixedly provided at each of the upper and lower ends of the panel, the fixing plates are bent, and the fixing plates are located within the positive projection range of the panel. When the module box is installed on the wiring rack, the parts with the smallest distance between the two fixing plates are respectively attached to the upper and lower ends of the module box.

[0014] Preferably, a guide block is provided on each side of the push buckle.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. In the traditional pre-terminated module box, each module is independent of each other, each module has an independent PCB connection shielded signal socket and IDC terminal block, each module has an independent shell, and the module is integrated in the module box, which makes the module box larger; the utility model integrates the shielded signal socket and IDC terminal block into one PCB board, and removes the shell of each module, so that the integrated design makes the module box smaller;

[0017] 2. The utility model adopts a 90° module with a PCB board as a carrier, that is, the wiring direction of the IDC terminal is at an angle of 90° to the cable entry direction, and the shielded signal socket is horizontally mounted on the PCB board, and the PCB board is horizontally fixed in the module box. This method reduces the overall thickness of the module box by changing the PCB board originally perpendicular to the wiring direction to a horizontal direction. With the improved structure of the wiring rack, after it is installed in the cabinet, there is a gap between the module boxes of the upper and lower layers of the wiring rack to ensure air circulation, which can enhance the heat dissipation efficiency between the upper and lower adjacent module boxes;

[0018] 3. The utility model sets metal isolation plates between modules to reduce the mutual crosstalk between modules;

[0019] 4. The utility model changes the connection mode between the module box and the patch panel from threaded connection to press buckle fixing, and sets guide blocks on both sides of the press buckle. The guide blocks play a guiding role during installation, making it easy to install the module box in place, and the disassembly and assembly are convenient and quick, which greatly improves the installation efficiency; BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: Example

[0027] like Figure 1 , Figure 2As shown, a highly integrated small-volume pre-terminated component for quick installation includes a module box 1, a PCB board 7 is fixedly provided in the module box 1, a plurality of 90° modules are welded on the PCB board 7, and the 90° module includes a shielded signal socket 4, an IDC fixing member 9, and an IDC terminal 10 arranged on the IDC fixing member 9. An isolation plate mounting frame 8 is detachably mounted on the IDC fixing member 9, a first buckle 13 is fixedly provided on the IDC fixing member 9, and the isolation plate mounting frame 8 is snapped with the first buckle 13. A metal isolation plate 11 is provided on the isolation plate mounting frame 8, a second buckle 12 is fixedly provided on the isolation plate mounting frame 8, and the metal isolation plate 11 is snapped with the second buckle 12. The 90° modules and the metal isolation plates 11 are staggered in sequence. The IDC terminal 10 and the shielded signal socket 4 are electrically connected through the PCB board 7; all the shielded signal sockets 4 are located at the front end of the module box 1, and a cable inlet and outlet 5 is provided at the rear end of the module box 1. In order to prevent the cables from moving randomly in the module box 1 , a cable trough 6 located inside the cable inlet and outlet 5 is fixedly provided in the module box 1 .

[0028] Traditional independent modules are provided with shell protection, and the independent modules are installed in a module box 1, and the thickness of the module box 1 is relatively large. In this embodiment, multiple 90° modules are integrated on a PCB board 7, and the PCB board 7 is horizontally fixed in the module box 1, which reduces the thickness of the module box 1; because there is no need to set a shell for a single module, the interior of the module box 1 is more compact, thereby reducing the volume of the module box 1. The metal isolation plate 11 is clamped to the isolation plate mounting frame 8 through the second clamp 12, and then the isolation plate mounting frame 8 is clamped to the IDC fixing member 9 through the first clamp 13, so that the metal isolation plate 11 is installed in the module to reduce the mutual crosstalk between modules.

[0029] like Figure 3 , Figure 4 As shown, the pre-termination assembly also includes a wiring frame 14 for simultaneously fixing multiple module boxes 1. The wiring frame 14 is provided with a mounting groove 15, a card slot 16 and a guide slot 17. The module box 1 is embedded in the mounting groove 15. The module box 1 is fixed with a press buckle 3 that can be embedded in the card slot 16 and a guide block 2 that cooperates with the guide slot 17. The guide block 2 is provided on each side of the press buckle 3. The guide block 2 on the module box 1 and the guide slot 17 on the wiring frame 14 provide a guiding effect for the module box 1 to be installed on the wiring frame 14, and at the same time limit the lateral displacement of the module box 1 after being inserted into the wiring frame 14. The design of the press buckle 3 on the module box 1 facilitates installation and disassembly.

[0030] The patch panel 14 includes a panel 18, and a fixing plate 19 is fixedly provided at each of the upper and lower ends of the panel 18. The fixing plate 19 is bent and located within the orthographic projection range of the panel 18. When the module box 1 is installed on the patch panel 14, the parts with the smallest distance between the two fixing plates 19 are respectively attached to the upper and lower ends of the module box 1. The bent structure of the fixing plate 19 makes the upper and lower ends of the module box 1 form a height difference relative to the upper and lower ends of the panel 18. Figure 5 As shown, after the module box 1 is installed in the cabinet along with the patch panel 14, a gap is left between the module boxes 1 on the upper and lower layers of the patch panel 14 for air circulation, which can enhance the heat dissipation efficiency between the upper and lower adjacent module boxes. An inclined surface 20 is provided on one of the fixing plates 19 facing away from the patch panel 14, and an inclined guide surface 21 cooperating with the inclined surface 20 is provided on the pressing buckle 3, which further facilitates the insertion of the module box 1 into the patch panel 14.
