Connector Terminal Positioning With Insertion Restrictors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors lack a structure to stabilize the position of terminals within the housing, leading to unstable assembly and potential erroneous insertion, which affects assemblability and increases the risk of incorrect assembly.
Innovation Solution
Incorporating insertion restrictors and protrusions in the connector design to guide and secure the terminals at the correct position, ensuring proper alignment and preventing erroneous assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no insertion restrictor structure is provided, then the connector structure remains simple, but the terminal position becomes unstable and erroneous assembly may occur
Solution Approach 1:
The patent introduces insertion restrictors as intermediary elements between the housing and terminal. These restrictors act as mediators that guide the terminal into the correct position during assembly, preventing erroneous insertion while maintaining a relatively simple overall connector structure. The protrusions on the terminal engage with the insertion restrictors to ensure proper positioning.
2Ease of operation
If insertion restrictors and protrusions are added to guide terminal positioning, then assembly accuracy improves, but the connector structure becomes more complex
Solution Approach 1:
The insertion restrictors are pre-positioned within the housing at predetermined locations. The protrusions on the terminal are designed to engage with these pre-positioned restrictors during the assembly process. This preliminary arrangement of positioning elements ensures that the terminal automatically assumes the correct position when inserted, improving assemblability without requiring complex adjustment mechanisms.

AI summary
A connector includes: a housing; a terminal accommodated in the housing; and a fastening member configured to electrically connect the terminal by fastening. The housing includes insertion restrictors arranged in a vicinity of the terminal. The terminal includes protrusions configured to be in contact with the insertion restrictors at a normal arrangement position of the terminal with respect to the housing. The insertion restrictors are arranged at different positions with respect to an insertion direction of the terminal into the housing. The protrusions are arranged at different positions with respect to the insertion direction of the terminal into the housing.
