Various external devices such as cameras, LED lights, communication devices or billboards are often installed on the pole body according to needs. The cables of external devices are conventionally installed on the pole body. The cables include power cords, signal cords, and communication lines for exchanging with other devices or peripheral devices. There are at least three wires. These three wires are used as round-trip lines to transmit current or signals. Electromagnetic fields are easily generated in the space where the cables are installed, forming electromagnetic radiation interference, which affects the transmission function of weak current signals.

[0003] In summary, there is an urgent need for a technical solution to solve the technical problem that the centralized installation cables on the pole body are prone to generate electromagnetic radiation interference, which affects the weak current signal transmission function in the cable.

DETAILED DESCRIPTION

[0078] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0079] Example 1

[0080] like Figure 1 to Figure 5 The present embodiment shown is a cable compartment pole column that is resistant to weak current interference, including a pole column body 1, a guide rail 2 is provided on the side wall of the pole column body 1, and two or more slide grooves 2a are provided on the guide rail 2, and the slide groove 2a is used to separate and arrange the cables of external devices. When installing external devices on the pole column body 1, different cables of the external devices are arranged in different slide grooves 2a on the guide rail 2 respectively. Through the separation of different slide grooves 2a, the cables are arranged in separate compartments to avoid contact between cables of different devices, thereby reducing the electromagnetic radiation interference caused by the centralized installation of cables and the influence on the weak current transmission signal. The guide rail 2 fits snugly with the side wall of the pole column body 1, which helps to improve the guide rail 2 on the pole column body 1. To ensure the stability of the installation, a plurality of connecting holes are provided at the relative positions of the guide rail 2 and the side walls of the pole body 1. The guide rail 2 and the pole body 1 are fixed by riveting or bolting through the connecting holes, so that the guide rail 2 and the pole body 1 are connected and fixed. The slide groove 2a includes a cable groove 2a1 and an installation groove 2a2. The installation grooves 2a2 are respectively arranged on both sides of the cable groove 2a1. The installation groove 2a2 is used for arranging cables and installing equipment connecting devices 4. The equipment connecting device 4 includes a special-shaped bolt fastener 4a and an external equipment connecting member 4b; the external equipment connecting member 4a is detachably connected to the installation groove 2a2 by the special-shaped bolt fastener 4a, which facilitates the installation and disassembly of the external equipment connecting member 4b.

[0081] The special-shaped bolt fastener 4a includes a special-shaped screw 4a1 and a nut 4a2, wherein the nut 4a2 is adapted to the rod column of the special-shaped screw 4a1, a hook wedge portion 4a3 is provided at one end of the special-shaped screw 4a1, and the hook wedge portion 4a3 matches the inner side wall of the mounting groove 2a2, which is beneficial to improving the stability of the installation of the special-shaped screw 4a1 and the mounting groove 2a2, and a limiting portion 4a4 is also provided on the special-shaped screw 4a1, wherein the limiting portion 4a4 and the hook wedge portion 4a3 are located at one end of the special-shaped screw 4a1 and are arranged at an angle of 90°, and the limiting portion 4a4 includes a limiting block, and a screw hole 4a41 is provided on the limiting block. A stud 4a42 is provided in the screw hole 4a41, and the stud 4a42 is threadedly connected to the screw hole 4a41. By rotating the stud 4a42 along the screw hole 4a41, one end of the stud 4a42 abuts against the bottom of the installation groove 2a2. The reaction force of the bottom of the installation groove 2a2 on the stud 4a42 can generate a pre-tightening force through the limit block to make the hook wedge part 4a3 abut against the inner wall of the installation groove 2a2, thereby achieving the purpose of positioning the special-shaped screw 4a1 in the installation groove 2a2, preventing the special-shaped screw 4a1 from moving and falling along the installation groove 2a2 under the action of gravity, and facilitating the operator to install the external device connector 4b on the special-shaped screw 4a1.

[0082] The hook wedge portion 4a3 is respectively provided with a first contact portion 4a31 and a second contact portion 4a32, the first contact portion 4a31 is in arc surface contact with the mounting groove 2a2, the second contact portion 4a32 is in line contact or point contact with the mounting groove 2a2, the first contact portion 4a31 and the second contact portion 4a32 can simultaneously contact with the inner wall of the mounting groove 2a2, the first contact portion 4a31 contacts with the inner wall of the mounting groove 2a2 to form a first pressing force, the second contact portion 4a32 contacts with the inner wall of the mounting groove 2a2 to form a second pressing force; the first pressing force along the normal line of the contact surface and the second pressing force along the normal line of the contact surface can intersect to form a wedge-shaped angle, so that the hook wedge portion 4a3 generates a clamping force on the mounting groove 2a2, has good stability, and can effectively reduce the force shaking of the external device connected to the special-shaped screw 4a1, and the hook wedge portion 4a3 is also provided with a profile 4a33, the profile 4 a33 is located between the first contact portion 4a31 and the second contact portion 4a32. When the first contact portion 4a31 and the second contact portion 4a32 contact with the inner wall of the mounting groove 2a2 at the same time, a gap is formed between the profile 4a33 and the inner wall of the mounting groove 2a2. Under the action of lateral external force, the hook wedge portion 4a3 of the special-shaped screw 4a1 serves as the main force-bearing portion. The contact portion between the first contact portion 4a31 and the mounting groove 2a2 and the contact portion between the second contact portion 4a32 and the mounting groove 2a2 are both prone to deformation. A buffer space for elastic deformation of the hook wedge portion 4a3 is formed through the gap between the profile 4a33 and the inner wall of the mounting groove 2a2, thereby forming a pre-tensioning force on the hook wedge portion 4a3 relative to the mounting groove 2a2. Under the action of the pre-tensioning force, the connection rigidity between the hook wedge portion 4a3 and the mounting groove 2a2 is reduced, and the special-shaped screw 4a1 is prevented from loosening.
