Compact Terminal With Slit Stabilizer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional male terminals have a large body size due to the need for a long hole to accommodate a stabilizer, leading to increased electrical resistance and compromised performance.
Innovation Solution
The terminal design incorporates a first slit on the top wall and a second slit on the auxiliary wall, with separated portions forming a stabilizer reinforcing section, engagement section, and tab-entry-prevention part, eliminating the need for a hole and allowing for a more compact design while maintaining guiding and prevention functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hole is provided on the top wall to accommodate the stabilizer and engagement section, then the stabilizer can be inserted and engaged properly, but the body part dimension becomes long and cannot be downsized
Solution Approach 1:
The invention changes the dimensional approach by forming the stabilizer and engagement section through slits and separated portions on the top wall and auxiliary wall, rather than using a through-hole. This allows the stabilizer to be accommodated in a planar configuration rather than requiring longitudinal depth, thereby reducing the body part dimension while maintaining engagement functionality.
Solution Approach 2:
The top wall and auxiliary wall are divided into separated portions by the slits, creating distinct functional regions for the stabilizer and engagement section. This segmentation allows each component to be formed independently in a compact arrangement, eliminating the need for a long continuous hole and enabling downsizing of the body part.
2Reliability
If the body part dimension is large, then the stabilizer can be accommodated, but the distance from terminal contact part to electric wire becomes large, increasing electrical resistance
Solution Approach 1:
By transitioning from a longitudinal hole configuration to a planar slit-based configuration on the top and auxiliary walls, the invention shortens the conductor path length while maintaining stabilizer accommodation. The conductor section maintains constant width and thickness without material deficiencies, reducing electrical resistance.
3Reliability
If a long hole is used to form the stabilizer entry space, then the stabilizer can be engaged, but the conductor section has material deficiencies increasing electrical resistance
Solution Approach 1:
The slit-based design segments the top wall and auxiliary wall to form the stabilizer and engagement section, eliminating the need for a long continuous hole that would create material deficiencies. The conductor section maintains constant cross-sectional dimensions throughout its length, ensuring uniform electrical conductivity and reducing resistance.

AI summary
A terminal is formed by bending a plate of electrically conductive metal and is received in a connector housing. The terminal includes a box-shaped body part, a terminal contact part provided on a front side of the body part, and an electrical wire connecting part provided on a rear side of the body part. When the plate before bending is viewed from the thickness direction, a conductor section having a cross-section having constant width and thickness extends from the terminal contact part to the electrical wire connecting part.
