Technical Field

The utility model relates to the technical field of new energy automobile parts, in particular to a novel PDU copper bar limiting structure of a new energy electric automobile.

Background

The high-voltage Distribution box is a Distribution box for short, PDU (Power Distribution Unit) for short in English, and a high-voltage power supply Distribution unit in a new energy vehicle high-voltage system solution. The high-voltage component is electrically connected through the busbar and the wiring harness, functions of charging and discharging control, high-voltage component electrifying control, circuit overload short-circuit protection, high-voltage sampling, low-voltage control and the like are provided for a high-voltage system of the new energy automobile, the operation of the high-voltage system is protected and monitored, and the PDU can also integrate functions of a BMS main control module, a charging module, a DC module, a PTC control module and the like. It is inside mainly including parts such as relay, PCB board, fuse and copper bar, among the PDU of prior art, do not design corresponding limit structure or directly do spacingly on the shell plastic in copper bar hookup location department, lead to some hookup location's uniformity poor, in-service use, increased electric risk, the reliability is lower, and the installation is consuming time longer.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a novel PDU copper bar limiting structure of a new energy electric automobile, which can perform better limiting operation on a wire nose structure connected on a copper bar, improve the position uniformity of PDU electric connection, increase the connection reliability and save the installation time.

In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:

the utility model provides a novel new forms of energy electric automobile PDU copper bar limit structure, includes the PDU shell, the inside bottom surface of PDU shell be equipped with mounting plate, mounting plate upper surface be fixed with a plurality of relay, fuse and PCB board through the draw-in groove, a plurality of relay, fuse and PCB board top between all be equipped with the copper bar, the copper bar on have a plurality of line nose through the screw fixation, the copper bar on connecting wire nose position department both sides all be equipped with a limit stop, limit stop pass through punching press technology processing on the copper bar surface, wherein the limit stop interval of both sides is less than the diameter of line nose, line nose card go into between the limit stop of both sides and through the screw fixation on the copper bar.

Furthermore, the outer side of the PDU shell is provided with a type plug-in interface.

Further, the copper bar on be equipped with a plurality of screw holes and be used for the installation screw, the copper bar pass through the screw fixation in a plurality of relay, fuse and PCB board top.

Furthermore, the cross section of the limit stop is rectangular and the height of the limit stop is larger than the thickness of the wire nose.

Compared with the prior art, the utility model has the following beneficial effects:

according to the utility model, the limit stop structures positioned on the two sides of the wire nose are arranged, so that a better limit effect can be realized, the position uniformity of PDU (protocol data Unit) electric connection is improved, the connection reliability is increased, and the aligned installation time is saved.
