Parallel Peripheral Battery Pack Cable Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cable connecting structure of battery packs requires large connectors and significant space for wiring, making the battery pack less compact and inefficient in terms of space utilization.
Innovation Solution
The cable connecting structure involves arranging battery pack side connectors in parallel along the peripheral wall with inclined axes, allowing cables to extend parallel to each other and separate from the wall, reducing the size of connectors and the required wiring space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single connector is used to connect two cables to the battery pack, then the wiring work is facilitated, but the connector size becomes large and the battery pack peripheral face size increases
Solution Approach 1:
The patent divides a single connector into multiple separate connectors (first cable side connector and second cable side connector). Each connector handles one cable independently, allowing them to be arranged in parallel along the peripheral wall. This segmentation reduces the size of each individual connector and the overall peripheral face area required, while still facilitating wiring work through modular connectivity.
2Ease of manufacture
If the connector axis is perpendicular to the peripheral face, then the connection is straightforward, but a large space is required for wiring the cables around the peripheral face
Solution Approach 1:
The patent changes the arrangement from a perpendicular connection (single dimension) to a parallel arrangement along the peripheral wall (multiple dimensions). The cable side connectors are positioned at different locations along the peripheral wall, allowing cables to be routed in multiple directions rather than all extending perpendicularly. This dimensional change reduces the wiring space required around the peripheral face.
3Device complexity
If multiple cables are connected through a single connector, then the connector structure becomes simplified, but the connector and battery pack face size increase
Solution Approach 1:
The patent segments the connector system into multiple independent cable side connectors, each handling a single cable connection. While this increases the number of connector components, each individual connector remains simple in structure. The segmented connectors are arranged in parallel along the peripheral wall, distributing the connection points and reducing the concentrated area required on the battery pack face.

AI summary
A cable connecting structure of a battery pack, the battery pack (18) which is provided in a vehicle, the cable connecting structure includes: a plurality of cable side connectors (24) which are provided at ends of a plurality of cables (22), respectively, and which are connected to the battery pack; and a plurality of battery pack side connectors (20) to which the cable side connectors are detachably mounted, and which are arranged in parallel along a peripheral direction of a peripheral wall (1805) of the battery pack. In a state where the cable side connectors (24) are mounted to the battery pack side connectors (20), portions of the cables (22) which are respectively withdrawn from the cable side connectors are extended along the peripheral wall (1805).
