Electrical Connector With Stopping And Position Limiting Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors lack stability during soldering to circuit boards due to the absence of structures to limit terminal and conductor movement, leading to inaccurate positioning and potential detachment, resulting in empty or missing soldering issues.
Innovation Solution
The electrical connector design incorporates accommodating holes with stopping and position limiting portions, where terminals and conductors are connected to strips and mounted upward from the bottom, ensuring accurate positioning and stable soldering by preventing excessive movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If terminals and electrical conductors are mounted into accommodating holes from top without upward limiting structures, then the mounting process is simple, but the terminals and electrical conductors move upward during soldering causing inaccurate positioning and unstable soldering
Solution Approach 1:
The accommodating hole is segmented into multiple functional regions: a mounting section for receiving the terminal and conductor, and limiting sections with stopping portions and position limiting portions that restrict upward movement. This segmentation allows the same hole to serve both easy mounting and precise positioning functions.
Solution Approach 2:
The stopping portions and position limiting portions are pre-formed in the accommodating hole before mounting. These preliminary structures prevent upward movement during subsequent soldering operations, eliminating the need for complex mounting procedures while ensuring positioning accuracy.
2Device complexity
If no structures are provided in accommodating holes to limit upward movement, then the device structure is simple, but the terminals and electrical conductors detach during soldering causing empty or missing soldering
Solution Approach 1:
The stopping portions and position limiting portions provide preliminary anti-action by preventing upward movement before the harmful effect of detachment can occur. These structures counteract the upward force generated during soldering, ensuring reliable soldering without requiring complex additional components.
3Device complexity
If terminals and electrical conductors are mounted from top without upward limiting structures, then the accommodating hole design is simple, but the molten solder cannot sufficiently flow back to soldered sections resulting in unstable soldering
Solution Approach 1:
The accommodating hole is divided into functional sections with stopping portions and position limiting portions that create a controlled environment for soldering. This segmentation ensures proper positioning that allows molten solder to flow back adequately to the soldered sections, improving soldering quality without complicating the overall design.

AI summary
An electrical connector includes an insulating body. At least one accommodating hole runs through the insulating body vertically, and each accommodating hole has a stopping portion and a position limiting portion. Each accommodating hole accommodates a terminal and an electrical conductor. The terminal is in contact with the electrical conductor. The terminal upward abuts the stopping portion. The terminal is connected to a first strip downward, and is mounted into the accommodating hole upward from bottom. The electrical conductor upward abuts the position limiting portion. The electrical conductor is connected to a second strip downward, and is mounted into the accommodating hole upward from bottom. The terminal upward abuts the stopping portion and thus does not excessively move upward, and the electrical conductor upward abuts the position limiting portion and thus does not excessively move upward.
