[0002] In security systems, the stability and anti-interference capability of signal transmission are crucial. Traditional signal distribution harnesses are susceptible to electromagnetic interference during transmission, leading to signal distortion or loss. Common-mode inductors are often used to suppress common-mode interference to improve the stability and anti-interference capability of signal transmission.

[0003] The prior art, disclosed in patent document CN218828266U, presents the following technical solution: a wire harness, comprising a wire and terminals disposed at both ends of the wire, wherein at least one set of positioning members for connecting to a wall is detachably disposed on the wire, the positioning member comprising a positioning sleeve sleeved on the outside of the wire, a positioning suction cup detachably disposed on the outer wall of the positioning sleeve, and a spring piece disposed on the positioning sleeve for pressing the wire, wherein the positioning sleeve has a positioning hole for the power supply wire to pass through, and one end of the spring piece is disposed on the hole wall of the positioning hole and the other end abuts against the wire.

[0004] If the positioning component in the above technical solution is reversed, it becomes difficult for the stop block to be stably engaged in the stop groove, causing the wire harness to be squeezed by the spring and fall off, resulting in poor stability and limited practical effect.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] This utility model provides a technical solution: such as Figure 1 and Figure 2As shown in this embodiment, a common-mode inductor integrated signal distribution harness for a security system includes a signal distribution harness 1. The signal distribution harness 1 includes a harness body 11, with connection terminals 12 at both ends of the harness body 11 for connecting security equipment. A common-mode inductor module is disposed in the middle of the harness body 11. The common-mode inductor module is fixed inside the harness using encapsulation or injection molding processes to ensure a stable connection with the signal line 111. The common-mode inductor module consists of a magnetic core and a coil wound on the magnetic core. The signal line 111 passes through the common-mode inductor module and is connected to both ends of the coil. The harness body 11 includes the signal line 111. Multiple lines 111 are provided. A shielding layer 113 is provided on the outside of the signal lines 111. The shielding layer 113 is used to shield external electromagnetic interference.

The insulating layer 114 is used to protect the wire harness. By covering the shielding layer 113 with the insulating layer 114, the wire harness can be protected. The shielding layer 113 and the common mode inductor module are used to suppress external electromagnetic interference. The shielding layer 113 is made of metal braided mesh material, which can effectively shield high-frequency electromagnetic interference and improve the stability and anti-interference ability of signal transmission.

[0026] like Figure 3 and Figure 4As shown, at least one set of wiring harness mounting structures 2 is provided on the signal distribution wiring harness 1. The wiring harness mounting structure 2 includes a mounting plate 21. Mounting holes 212 are provided around the mounting plate 21. The mounting holes 212 are connected to a wall or bracket.
