Y-shaped electrical connector used between tractor and trailer and power taking method thereof

Abstract

The invention provides a trailer Y-shaped branch power taking connector and relates to the field of continuous branch power taking connectors between tractors and trailers. A Y-shaped continuous powertaking connection device is arranged at the end of the trailer Y-shaped branch power taking connector. The trailer Y-shaped branch power taking connector comprises a seven-core-wire or five-core-wirepower plug socket which meets an ISO 7638 standard; a positive power wire connected with a second pin defined in the ISO 7638 standard is led out of the branch power taking connector; the tail end ofa connection wire of a branch power wire is equipped with a standard rapid connection socket; a negative wire is led out of a two-hole rapid connection socket and is bonded with a trailer to form anindependent current circuit so as to cause no influence on other circuit appliances. Compared with the prior art, the trailer Y-shaped branch power taking connector has the beneficial effects that theexisting trailer electrical connector is improved under the condition that the standards at home and abroad are met, a group of additional parallel circuits are added and are used for supplying powerto newly added intelligent devices; the problem that the existing electrical connector is not provided with sufficient ports and is incapable of supplying power to new devices is solved in the premise of ensuring that the new electrical connector is safe and effective.

Description

technical field [0001] The invention relates to the field of electrical connectors for trucks, in particular to a power connector used between a tractor and a trailer. Background technique [0002] A trailer is an unpowered vehicle that needs to be towed behind a truck, tractor, or other vehicle. The trailer itself includes lighting, alarms and other electrical equipment. These devices require an electrical connector between the trailer and the tractor for signal and power transmission, and then the tractor can effectively control the equipment in the trailer. Due to different standards in different countries, the existing electrical connectors are mainly divided into 12V power supply and 24V power supply. The United States uses 12V, and Europe and China both use 24V. In 24V power supply, the main international standards are 15-pin connection standard ISO 12098 mainly used for lighting and ISO 7638-1 for ABS / EBS 7-pin connection standard. The corresponding Chinese national ...

AI Technical Summary

Problems solved by technology

[0003] The existing electrical connector standards between tractors and trailers can no longer fully meet the existing working environment. The main ISO 12098 and ISO 7638 standards have been around for more than ten years. After the promulgation of GB7258-2017, the need To improve the driver's perception of the whole car and the trend of high-level Internet and Internet of Things in cars, more and more equipment is needed on the trailer, such as GPS, temperature control, camera monitoring, reversing radar, hydraulic lift, data acquisition and interaction system, etc.

However, the power supply scheme for these additional devices is not perfect, and the existing power supply standards and equipment cannot scientifically and reasonably provide power for the new devices. Therefore, when these devices need to be used, they can only bring their own power supply or use 15-core, 7-core Retrofit of electrical connectors to provide power

But now the blind modification of 15-pin and 7-pin electrical connectors will not only affect the power supply of existing equipment and cause new hazards, but also cannot meet the power demand of new equipment and industry regulations, which greatly restricts the intelligence of trailers. development
