Downsized Terminal Box Body Slit Stabilizer Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional male terminals have a long body shape due to the need for a hole to accommodate a stabilizer and engagement section, leading to increased electric resistance and reduced electrical performance.
Innovation Solution
The terminal features a first slit on the top wall and a second slit on the auxiliary wall, allowing for the formation of stabilizer, stabilizer reinforcing section, and engagement section without a hole, thereby downsizing the body part and reducing electric resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a hole is provided on the top wall to accommodate the stabilizer and engagement section, then the stabilizer and engagement section can be properly formed, but the body part becomes long and cannot be downsized
Solution Approach 1:
The patent transitions from a three-dimensional hole structure to a two-dimensional slit structure on the top wall. The first and second slits are arranged in different directions (first direction and second direction respectively), allowing the stabilizer and engagement section to be formed without requiring a deep hole, thus reducing the longitudinal dimension L2 of the body part while maintaining functional stability.
2Stability of the object's composition
If the body part length is increased to accommodate a hole for stabilizer, then the stabilizer and engagement section can be formed, but the electric resistance increases and electrical performance deteriorates
Solution Approach 1:
By changing from a hole structure to slit structures arranged in different directions, the patent reduces the longitudinal length L2 of the body part. This shortening of the conductive path directly reduces electric resistance and improves electrical performance while the slits still provide sufficient space for forming the engagement section and stabilizer.
3Stability of the object's composition
If a long hole is provided for stabilizer and engagement section, then these components can be formed, but the body part dimension L2 increases
Solution Approach 1:
The patent divides the single hole structure into multiple separate slits (first slit and second slit) arranged in different directions. The first slit extends in a first direction and the second slit extends in a second direction, segmenting the space requirement into smaller, directional components that fit within a compact L2 dimension while still accommodating both stabilizer and engagement section.
Solution Approach 2:
The patent uses slits extending in different directions (first direction and second direction) rather than a single long hole, effectively utilizing two-dimensional space arrangement to reduce the longitudinal dimension L2 while providing sufficient space for both stabilizer and engagement section formation.

AI summary
A terminal includes a box-shaped body part including a pair of a first side wall and second side wall which are raised from both side ends of a bottom wall, a top wall extended from the first side wall, and an auxiliary wall extended from the second side wall. The top wall includes a first slit opening on a side end face of the top wall. The auxiliary wall includes a second slit opening on a side end face of the auxiliary wall. A stabilizer is formed by a portion on a front side of a separating portion formed by the second slit. A stabilizer reinforcing section is formed by a portion on a front side of a separating portion formed by the first slit. An engagement section is formed by a portion on a rear side of the separating portion formed by the first slit of the top wall.
