Terminal Mounting Structure with Perpendicular Wings for Lance Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional terminal-mounting structures face challenges in space efficiency due to the inwardly bent heat-dissipating portions, which prevent the lance from locking into the locking hole from the intended side, resulting in increased inner dimensions of the tube portion.
Innovation Solution
A terminal-mounting structure featuring elongated plate-shaped connecting portions with perpendicular wings that allow the lance to be locked between them, along with lance-protecting walls and tapered portions to guide the terminal into position, ensuring smooth insertion and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the heat-dissipating portions are inwardly bent at a right angle to dissipate heat, then heat dissipation function is improved, but the lance cannot be passed between the tip portions to lock into the locking hole from the intended side, resulting in increased inner dimension of the tube portion
Solution Approach 1:
The heat-dissipating portion is divided into multiple segments (first heat-dissipating portion and second heat-dissipating portion) that are bent at different angles. The first heat-dissipating portion is bent at an acute angle while the second is bent at an obtuse angle, creating sufficient clearance for the lance to pass through and lock into place while maintaining effective heat dissipation surface area.
2Volume of moving object
If the heat-dissipating portions are inwardly bent to create compact structure, then space efficiency is improved, but the locking mechanism cannot be accessed from the intended side
Solution Approach 1:
The heat-dissipating portions are designed with dynamic bending angles - the first portion bends at an acute angle and the second at an obtuse angle. This dynamic angular configuration allows the structure to maintain compactness while creating an operational pathway for the lance to access the locking hole from the intended side, enabling proper locking operation.
3Temperature
If the distance between tip portions of heat-dissipating portions is reduced, then heat dissipation efficiency is improved, but the lance cannot be passed between them for locking
Solution Approach 1:
Different regions of the heat-dissipating portion are given different bending characteristics. The first heat-dissipating portion bends at an acute angle while the second bends at an obtuse angle, creating a local quality difference that provides sufficient clearance for lance insertion while maintaining close proximity of heat-dissipating surfaces for efficient heat dissipation.

AI summary
The invention provides a terminal-mounting structure for mounting a terminal to a terminal-receiving portion, which includes the terminal and the terminal-receiving portion. The terminal includes an elongated plate-shaped connecting portion, a pair of wings extending from both edges of the connecting portion which are disposed in a width direction of the connecting portion and being perpendicular to the connecting portion, and a locking hole formed in the connecting portion and located between the pair of wings. The terminal-receiving portion includes a tube portion for receiving the terminal therein, and a lance capable of being locked to the locking hole of the terminal and positioned between the pair of wings. A front face of the connecting portion is not covered by the pair of wings at all. The pair of wings extends in a same direction.
