[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] The weak signal enhancement and isolation device has a partition 1;

[0024] like Figures 1 to 5 As shown, a junction box 2 is rotatably connected to both sides of the partition 1. The opposite side of the junction box 2 is open. The junction box 2 has grooves 21 equidistantly arranged inside. The junction box 2 has wiring ports 22 equidistantly arranged on both sides. The two ends of the grooves 21 are connected to the corresponding wiring ports 22. An extrusion plate 3 is slidably connected inside the junction box 2. An extrusion strip 31 is equidistantly arranged on one side of the extrusion plate 3. The extrusion strip 31 is aligned with the grooves 21 of the corresponding junction box 2. A screw 4 is fixedly connected to the center inside the junction box 2. One end of the screw 4 passes through the corresponding extrusion plate 3 and is threadedly connected to a nut 5 on the outside.

[0025] The two junction boxes 2 on both sides of the partition 1 are used to separate strong and weak electrical cables to prevent electromagnetic interference. The rotatable design of the junction box 2 allows the orientation of the wiring port 22 to be adjusted by rotation to adapt to different wiring needs. The cross-section of the partition 1 and the junction box 2 is square, and the center of both sides of the partition 1 and the center of the corresponding side of the junction box 2 are rotatably connected by a rotatable connector. This design allows the junction box 2 to completely overlap with the partition 1 again after rotating 90 degrees.

[0026] The cable can be inserted into the groove 21 inside the junction box 2 from the terminal 22. In order to ensure a secure connection of the cable and prevent it from falling off, the pressing plate 3 can be pushed to slide inside the junction box 2 by rotating the nut 5, thereby pressing the pressing strip 31 to press the cable, ensuring good contact and secure connection between the cable and the junction box 2.

[0027] In addition, for weak electrical signals that need to be transmitted over long distances, a signal amplifier can be integrated inside the junction box 2. The signal amplifier can enhance the transmission distance and stability of the signal, ensuring that the weak electrical signal is not lost or interfered with during transmission. Secondly, in practical applications, in order to further improve electromagnetic compatibility, a dedicated grounding terminal can be set inside the junction box 2 to conduct interference signals to the ground, thereby further protecting the transmission quality of the weak electrical signal.

[0028] likeFigures 1 to 5 As shown, the nut 5 is a butterfly nut 5, which is convenient for manual operation, and the pressing plate 3 can adjust the compression degree of the cable by manual operation, so as to ensure the stable connection between the cable and the electricity connection box 2.

[0029] As shown in the drawings, Figures 1 to 5 As shown, the partition plate 1 is fixedly connected with the magnet 11 at four corners, and the electricity connection box 2 is provided with the metal sheet 23 at four corners on the opposite side, and the two sides of the magnet 11 are respectively magnetically attracted to the corresponding metal sheet 23, so that when the electricity connection box 2 needs to be rotated, the magnetic attraction force between the magnet 11 and the metal sheet 23 can keep the stability of the electricity connection box 2 at a specific position, preventing accidental rotation.

[0030] As shown in the drawings, Figures 1 to 5 As shown, the electricity connection box 2 is fixedly connected with the wire sleeve 24 on the outside of the wire port 22 on both sides, and the flared wire sleeve 24 makes the cable more smooth when inserted into the wire port 22, reducing the friction and damage between the cable and the wire port 22.

[0031] As shown in the drawings, Figures 1 to 5 As shown, the corrugated groove 32 is arranged on the corresponding surface of the pressing strip 31 and the groove 21, so that when the pressing plate 3 is pressed against the cable by rotating the nut 5, the corrugated groove 32 can more effectively grab the surface of the cable to prevent it from sliding or falling off.

[0032] As shown in the drawings, Figures 1 to 5 As shown, one of the electricity connection boxes 2 is provided with the mounting sheet 6 on the top, and the mounting sheet 6 is provided with the gourd-shaped hole 61 on the surface, so that the electricity connection box 2 can be fixed on the wall, cabinet or other supporting structure by the fastener such as bolt.

[0033] As shown in the drawings, Figures 1 to 5 As shown, the electricity connection box 2 and the pressing plate 3 are provided with the anti-interference layer such as copper foil or tin foil on the surface, which can shield the interference of external electromagnetic field and improve the transmission stability and anti-interference ability of the signal.

[0034] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
