Parallel Side Wall Neck for Resin Molding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection terminals require precise positioning and management of a resin blocking piece during resin molding, which is time-consuming and prone to errors due to inclined side walls and potential damage from misalignment.
Innovation Solution
The connection terminal features parallel side walls in the neck portion, allowing the resin blocking piece to be easily positioned within its range, and a die configuration with a resin blocking piece that matches these parallel walls for accurate resin molding, preventing gaps and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If inclined side walls are used in the neck portion, then the width dimension can be narrowed from the terminal connection portion to the wire connection portion, but the resin blocking piece requires precise positioning and management which is time-consuming and prone to errors
Solution Approach 1:
The patent changes the geometric parameters of the neck portion by introducing parallel side walls with a specific width that is equal to or slightly larger than the resin blocking piece. This parameter change transforms the positioning requirement from high-precision (with inclined walls) to tolerance-friendly (with parallel walls), allowing the resin blocking piece to be easily positioned within the parallel walls without requiring precise alignment.
2Reliability
If the resin blocking piece is positioned shifted from the predetermined position, then gaps are formed preventing reliable resin blocking, but with parallel side walls the resin blocking piece can be easily positioned within its range
Solution Approach 1:
The patent designs the parallel side walls with a width that provides a margin of error (cushioning) around the resin blocking piece. This beforehand cushioning ensures that even if the resin blocking piece is not perfectly positioned, it will still be contained within the parallel walls and perform its resin-blocking function reliably, preventing gaps while accommodating positioning variations.
3Shape
If inclined side walls are used, then the neck portion can transition between different width dimensions, but the resin blocking piece or side walls may be damaged when attempting to set
Solution Approach 1:
The patent applies different geometric qualities to different parts of the neck portion: the upper part maintains the inclined configuration for width transition, while the lower part features parallel side walls for safe resin blocking piece insertion. This local quality differentiation allows the neck portion to perform both functions - geometric transition and protected component insertion - without compromising the integrity of the resin blocking piece.

Function Achieved in This Case
This design simplifies the positioning and management of the resin blocking piece, ensuring reliable resin molding without gaps or damage, thereby improving manufacturing efficiency and reducing the risk of errors.
Implementation Method 1
a resin is poured into a cavity 141a inside the lower die 141 and the upper die (not shown) and the resin covering portion 130 is produced by the poured resin being set

AI summary
A connection terminal includes a terminal connection portion to be connected with a partner terminal, a wire connection portion connected with a wire, a neck portion connecting the terminal connection portion and the wire connection portion, and a resin covering portion covering a connection portion of the wire connection portion and the wire. The neck portion has a bottom wall and a pair of side walls installed upright from both sides of the bottom wall and having parallel wall portions equally spaced from each other.
