External vehicle-mounted power supply wall box

Abstract

The invention discloses an external vehicle-mounted power supply wall box, and relates to the technical field of vehicle-mounted power supplies. According to the technical scheme, the external vehicle-mounted power supply wall box comprises a power supply wall box, a negative grounding assembly is fixedly mounted in the power supply wall box, a positive wiring assembly is fixedly mounted on the inner wall of the power supply wall box, a wire arrangement assembly is detachably connected to the outer wall of the positive wiring assembly, the power supply wall box comprises a box body, a null line box and an insulating layer, the negative grounding assembly comprises a grounding wire, a negative binding post, a wire holder and a negative terminal, and the positive wiring assembly comprises a positive conductor, a positive lead, a main wire holder, a wire harness deconcentrator, a branch wire and a wiring lug. When other electric equipment needing to be connected with a vehicle-mounted battery in the power supply wall box is wired, the negative electrode of the vehicle-mounted electric equipment is directly connected with the negative terminal to form a negative electrode loop, a negative electrode wire in the power supply wall box system is replaced by the null line box, the space utilization rate in the power supply wall box is increased, and meanwhile, the wiring efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle power supplies, in particular to an external vehicle power supply wall box. Background technique [0002] The power wall box is suitable for the mains power supply of the vehicle information system and the vehicle command and control system. It monitors the power supply and the power safety of the system, provides safety protection and sends out an alarm signal when a fault is found. The external power supply is connected to the load input terminal through the wall box panel, and the electrical device with protection, detection, and alarm functions is added between the vehicle power supply and the vehicle-related electronic equipment. The power wall box and the electrical protection device on the inner wall of the power wall box It effectively improves the safety of automobile electrical use, and can detect power supply equipment in time to prevent the failure of circuit faults to be found in time...

AI Technical Summary

Problems solved by technology

[0003] The existing technology has the following disadvantages: the external vehicle power supply wall box has many internal wiring harnesses, when connecting the vehicle power supply and multiple groups of vehicle electrical equipment, in order to ensure the safety of electricity use, it needs multiple circuits according to the power equipment of different electrical equipment, resulting in many The wiring harnesses are accumulated together. At present, there are more and more intelligent equipment in automobiles, and more and more wiring harnesses are required. The wiring harnesses in the existing power supply wall boxes usually need positive and negative wires to form a loop. There are relatively many wiring harnesses. Usually, multiple groups of wires are wrapped into one group with cable ties, which is not easy to distinguish one by one when connecting, and it is not conducive to the heat dissipation of the wire harness in the power wall box
