Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, specifically to a signal interface connection structure for floodlighting fixtures suitable for multimodal sensing. Background Technology

[0002] Floodlights are a type of lighting fixture that provides uniform illumination over a wide area. They are commonly used in plazas, stadiums, and building exteriors. They are characterized by strong light diffusion and no significant glare. They are typically connected in a standardized manner through a multimodal sensing signal interface, allowing simultaneous access to and processing of multiple sensor signals (such as ambient light, temperature and humidity, motion detection, etc.). Through a unified interface, they enable power supply, data exchange, and intelligent control, thereby expanding the lighting fixture's sensing and interaction capabilities and meeting the complex functional requirements of smart cities, security, and other applications.

[0003] Currently, the application of multimodal sensing signal interfaces in floodlighting fixtures is becoming increasingly widespread. However, existing connection structures generally suffer from loosening issues, affecting the stability of signal transmission. Traditional interfaces often employ simple spring pins or snap-fit ​​designs, which are prone to mechanical wear under frequent plugging and unplugging or long-term vibration environments (such as outdoor wind loads and equipment operation vibrations), leading to poor contact. Furthermore, the integration of multiple interfaces increases structural complexity. If a reliable locking mechanism is not adopted, the connectors are prone to displacement or even detachment due to external forces, affecting the continuous and stable operation of the multimodal sensor.

[0004] Therefore, there is an urgent need for a vibration-resistant and non-loosening signal interface structure to meet the reliable connection requirements of floodlighting fixtures in complex environments. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a signal interface connection structure for floodlighting fixtures suitable for multimodal sensing. It has the advantages of vibration resistance and anti-loosening, and reliable connection in complex environments, thus solving the problems mentioned in the background technology.

[0006] This utility model provides the following technical solution: a signal interface connection structure for floodlighting fixtures with multimodal sensing, including a male connector and a female connector. One end of the male connector is engaged with one end of the female connector. A threaded joint is fitted on the surface of the male connector.

A wedge block two corresponding to the wedge block one is fixedly provided on one side of the inner ring. One side of the wedge block two is slidably connected to the guide groove. A plurality of slide rods two are fixedly provided on the other side of the inner ring. A spring two is sleeved on the surface of the slide rod two. One side of the outer ring is fixedly connected to one end of the slide rod two.

[0010] As a preferred technical solution of this utility model, one end of the positioning sleeve is provided with a rod groove two that is slidably connected to the slide rod two, and a rubber ring two is engaged with one side of the rod groove two.

Then push the positioning sleeve 6 so that the buckle 703 passes through the limit ring 4. Finally, release the outer ring 805. After the outer ring 805 is released, the second spring 804 can push the outer ring 805 to reset. The outer ring 805 can drive the second wedge block 802 to reset through the inner ring 801, without interfering with the reset activity of the buckle 703. The first spring 702 can push the buckle 703 to reset and can provide support for it.
