Description

Technical Field

[0001] The utility model belongs to the field of data line terminals, and in particular relates to a line terminal connecting mechanism for a public transportation data collection device. Background Art

[0002] Public transportation refers to transportation services provided to the public, usually including buses, subways, light rail, and other forms. Traffic data collection equipment can collect, monitor and analyze information such as traffic flow, speed, and vehicle type. They play an important role in traffic management, urban planning, and intelligent transportation systems.

[0003] The connection structure of the wire end of the existing public transportation data collection device is often to connect the vehicle computer and the data collection equipment through a single socket and plug structure. However, when the vehicle is driving, due to the ground or traffic conditions, the vehicle will usually experience bumps or sudden brakes. The vibration caused by bumps and sudden brakes and the collision of external objects can easily cause displacement or damage to the existing data line end of the single connection structure, thereby affecting the effect and efficiency of the data collection equipment in collecting vehicle driving data.

[0004] Therefore, in order to address the problem that the above-mentioned existing line segment connection structure has poor stability when used to collect public transportation data, and the vibration generated by the vehicle during driving can easily cause the line segment to fall off or be damaged, a data line end connection mechanism for a public transportation data collection device has been developed. By adding an external threaded sleeve structure, an internal sleeve structure and a multi-layer snap-on structure to the data line end, the existing data line end equipment can cope with the vibration and collision generated by public transportation during driving, thereby preventing the data line end from falling off or being damaged when collecting vehicle data.
