Description

A coaxial power supply cable for cameras Technical Field

[0001] This utility model relates to the field of camera accessories, and in particular to a coaxial power supply cable for cameras. Background Technology

[0002] The development of coaxial power supply cables for cameras stems from the inherent flaws of separate power and signal transmission cabling in traditional surveillance systems. In existing solutions, cameras typically require separate power cables (such as RVV 2×1.0mm²) and video transmission cables (such as coaxial or twisted-pair cables). This separate cabling architecture significantly reduces construction efficiency. Specifically, installation requires dual path planning for both types of cables, especially in concealed spaces like conduits, cable trays, or ceilings, where parallel laying increases conduit diameter requirements and exacerbates the risk of cable tangling. To simplify the cabling process, some improvements attempt to physically integrate the power conductor with the coaxial cable, but existing integration technologies have significant limitations. While co-constructing the 12V / 24V power line with the outer conductor layer of the coaxial cable allows for single-wire power supply and video transmission, it causes expansion of the cable's outer diameter, making cabling difficult at corners. Summary of the Invention

[0003] The purpose of this invention is to provide a dedicated coaxial power supply cable for cameras to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A coaxial power supply cable for cameras includes a fixed base, a fixed post, a connecting rod, a rotating base, a gas spring, a piston rod, a fixed cap, a lifting handle, a shock-absorbing pad, and a connecting stud. The fixed base has a fixed post welded to its top center. A universal rotating ball is installed inside the fixed post, and the connecting rod is mounted through the universal rotating ball. The rotating base is welded to the top of the connecting rod. A gas spring is installed on the top of the rotating base. A piston rod is installed inside the top center of the gas spring. A fixed cap is installed on the top of the piston rod. A lifting handle is installed on the side of the fixed cap. A shock-absorbing pad is installed on the top of the fixed cap, and a connecting stud is welded to the top center of the fixed cap. The connecting stud is connected to the bottom of the camera device.

[0006] Preferably, the coaxial power supply camera cable also includes a reserved slot and a multi-diamond shielding layer. The rectangular protective sleeve has a vertical reserved slot in the center, and the upper and lower ends of the reserved slot are equipped with a multi-diamond shielding layer composed of multiple diamond shapes.

[0007] Preferably, the coaxial power supply camera cable also includes adhesive tape, and the top of the rectangular protective sleeve is covered with adhesive tape for wiring.

[0008] The beneficial effects of this utility model are: the utility model is reasonably designed, and the power cord and video transmission line are combined by the external rectangular protective sleeve, which facilitates wiring and organization, and has good video signal transmission and anti-interference capabilities.

[0011] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0012] As shown in Figure 1, a coaxial power supply camera cable includes a rectangular protective sleeve 1, a filler layer 2, an insulation layer 3, a wire core 4, a sheath 5, a shielding mesh 6, copper-plated tin foil 7, a PE transparent conductor 8, and an oxygen-free copper conductor 9. A filler layer 2 is installed around the right side of the rectangular protective sleeve 1. An insulation layer 3 is installed inside the filler layer 2, and the wire core 4 is installed at the center of the insulation layer 3. A sheath 5 is installed around the left side of the rectangular protective sleeve 1. A shielding mesh 6 is installed around the inside of the sheath 5. Copper-plated tin foil 7 is installed around the inside of the shielding mesh 6. A PE transparent conductor 8 is installed around the inside of the copper-plated tin foil 7, and an oxygen-free copper conductor 9 is installed at the center of the PE transparent conductor 8. The coaxial power supply camera cable also includes a pre-drilled slot 10 and a multi-diamond shielding layer 11. A vertical pre-drilled slot 10 is formed in the center of the rectangular protective sleeve 1, and a multi-diamond shielding layer 11 composed of multiple diamond shapes is installed at both the top and bottom ends of the pre-drilled slot 10. The coaxial power supply camera cable also includes adhesive tape 12, and the top of the rectangular protective sleeve 1 is covered with adhesive tape 12 for wiring.

[0013] The working principle of this utility model is as follows: the power cable and data cable are integrated by a rectangular protective sleeve 1, and a reserved slot 10 is set in the center. The built-in multi-diamond shielding layer 11 can further isolate signal interference and can generate a certain deformation when the cable is turned to adapt to the bending of the rectangular protective sleeve 1.
