Integrated Low-Voltage Terminal Housing for High-Voltage Battery Boxes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-voltage power distribution devices require a large number of components, increasing complexity and cost, while exposing low-voltage terminals to risks of damage and environmental factors.
Innovation Solution
Integrate low-voltage terminals into the housing or cover body of the high-voltage box, incorporating protective shells and guide structures to reduce component count, enhance safety, and improve assembly accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If low-voltage terminal is separately disposed outside the high-voltage box, then the terminal is accessible for connection, but the number of components increases and the terminal is exposed to environmental risks
Solution Approach 1:
The patent integrates the low-voltage terminal directly into the housing of the high-voltage box, merging two previously separate components (terminal and housing) into one unified structure. This eliminates the need for separate mounting brackets, external connectors, and protective covers, thereby reducing the total component count while simultaneously protecting the terminal from environmental factors such as rainwater and foreign objects.
2Device complexity
If low-voltage terminal is integrated into the housing, then the number of components is reduced, but the terminal may be harder to access for connection
Solution Approach 1:
The patent applies local quality by creating a specific opening or access port in the housing at the location where the low-voltage terminal is integrated. This opening allows external connectors to access the terminal for electrical connections while the rest of the housing remains closed and protective. The access area is locally modified to provide functionality without compromising the overall integrated structure.
3Reliability
If protective shell is added around low-voltage terminal, then the terminal is protected from environmental factors, but the occupied space increases
Solution Approach 1:
The protective function is merged into the housing structure itself. The housing serves dual purposes: it provides the structural enclosure for the high-voltage box and simultaneously acts as the protective shell for the integrated low-voltage terminal. This eliminates the need for an additional separate protective shell, thereby protecting the terminal without increasing the overall occupied space of the device.

AI summary
A high-voltage power distribution apparatus, a battery and an electrical apparatus. The high-voltage power distribution apparatus comprises a housing, a cover body and a low-voltage terminal; the housing has an opening; the cover body seals the opening, and forms a mounting chamber with the housing; the low-voltage terminal is integrated onto a target member, the target member being the housing or the cover body; a first end of the low-voltage terminal is exposed outside the mounting chamber, and a second end of the low-voltage terminal is electrically connected to a low-voltage circuit inside the housing; at least one side wall of the target member is provided with a protective housing having an outward opening; the first end of the low-voltage terminal is located inside the protective housing.
