AI Technical Summary

⚠Technical Problem

Traditional PDU modules have a single connection terminal lead-out method, which reduces installation flexibility and causes inconvenience for later maintenance and disassembly.

⚗Method used

Design a PDU module structure in which the second end of the connection terminal is staggered from the PCB board and the relay, so that it can be connected to the external cable from the front or the back. Combined with the PCB board, it is divided into two boards that integrate the power supply and control circuits respectively. Multiple relays and busbars are used to achieve flexible control.

🎯Benefits of technology

It improves the installation flexibility of PDU modules in the whole machine, simplifies the maintenance and disassembly process, reduces the processing complexity of PCB boards and electromagnetic interference, and reduces the number of wire harnesses and manufacturing costs.

Abstract

This utility model discloses a PDU module structure, relating to the field of PDU structure design technology. The PDU module structure includes a PCB board, a relay, and connection terminals. The connection terminals have a first end for connecting to high-voltage lines on the PCB board and a second end for connecting to external cables. The second end is offset from the PCB board and the relay, thus eliminating installation position limitations when connecting the second end to the external cable. Compared to the traditional onboard layout of the connection terminals for high-voltage lines, this allows for connection to external cables from either the front or back of the PDU module structure (no longer obstructed by relays or other components), improving the flexibility of PDU module installation on the entire device and facilitating subsequent maintenance and disassembly of the PDU module.
