Electrical Connector Fitting Holes Force Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors face challenges in stabilizing the quality of energization due to external forces being transferred to the connection point between the terminal clasp and the conductive component, particularly when soldering is used for fixation, leading to instability in the electrical connection.
Innovation Solution
The connector design incorporates fitting holes at corner parts on the extension region's peripheral area, a lock mechanism that presses the through-hole periphery against the installation surface, and a holding structure to secure the housing and cover in place, redirecting external forces away from the electrical connection area and reducing load on the connection point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conductive component extends out of the housing with soldering fixation, then electrical connection is achieved, but external force is transferred to the connection place causing instability
Solution Approach 1:
The patent introduces an intermediary fixing structure (clips, lugs, or tabs) between the conductive component and the housing. These intermediaries absorb and distribute external forces, preventing direct transfer to the soldered electrical connection point. The fixing structure acts as a mechanical buffer that decouples the electrical connection from mechanical stress.
Solution Approach 2:
The patent segments the connection system into distinct functional zones: an electrical connection region (soldering area) and a mechanical fixing region (clips/lugs/tabs). By separating these functions spatially, the electrical connection remains undisturbed by mechanical forces applied to the extending conductive component.
2Reliability
If fixation structure is added to reduce force transfer, then connection stability improves, but device complexity increases
Solution Approach 1:
The patent merges the fixing structure with either the housing or the conductive component itself, rather than adding entirely separate elements. The clips, lugs, or tabs are integrated into existing components, achieving force distribution while minimizing additional parts and assembly steps.
Solution Approach 2:
The fixing structure serves multiple functions simultaneously: it provides mechanical retention of the conductive component, distributes external forces away from the electrical connection, and maintains positional alignment. This multi-functionality reduces the need for additional specialized components.

AI summary
A connector includes a terminal clasp (10), a flexible flat conductive component (40), a housing (20) in which an electrical connection part (12) of the terminal clasp protrudes out of an opening (20b) of a storage room (20a), and a cover (30) that covers the electrical connection part from outside together with at least part of the housing. The flexible flat conductive component includes an electrical connection region (40a1) in which the electrical connection part is connected with a conductor, a peripheral region (40a2) enclosing the electrical connection region, an extension region (40b) extending out of the housing and the cover connected with each other, and at least two fitting holes (42) provided on the extension region side in the peripheral region.
