Bent Terminal Wire Holding Structure to Prevent Outward Movement

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for crimping and fixing conducting wires in electronic components often result in outward movement of the wire, leading to unstable electrical and physical connections between the wire and the conductive member.

Innovation Solution

The electronic component features a bent terminal with a base portion, a folding portion, and a bending portion. The conducting wire is sandwiched between these portions, and the bending portion is bent towards the base portion, ensuring a gap smaller than the wire's width after crimping, thereby securely holding the wire.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a flat plate shaped folding portion is bent to hold the conducting wire, then the conducting wire can be fixed, but the conducting wire moves outward causing unstable connections

Engineering Contradiction:

Improveconnection stabilityVSAvoidwire positioning

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The bent terminal is divided into three functional segments: a base portion for support, a folding portion for crimping, and a bending portion for guiding. This segmentation allows each part to perform its specific function optimally, preventing wire outward movement while maintaining connection stability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bending portion acts as an intermediary element between the base portion and the folding portion. It guides the conducting wire during the crimping process and prevents the wire from moving outward, thereby ensuring stable connections without compromising ease of operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Strength

If the folding portion is bent to crush the conducting wire, then the wire is held securely, but the wire may move outward during crimping

Engineering Contradiction:

Improveholding forceVSAvoidwire position accuracy

Core Design Contradiction:

StrengthVSManufacturing precision

Solution Approach 1:

The bending portion is formed in advance before the crimping process. This preliminary action creates a guiding structure that prevents wire outward movement during crimping, ensuring both strong holding force and high manufacturing precision without requiring additional steps.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The bending portion provides preliminary anti-action by opposing the outward movement of the wire before the crimping force is applied. This prevents the wire from shifting during the crimping process, maintaining both holding strength and position accuracy.

Inventive Principle:

Principle #9Preliminary anti-action

3Reliability

If the gap between the bending portion and base portion is small, then the wire is held tightly, but the wire cannot be easily inserted

Engineering Contradiction:

Improveconnection stabilityVSAvoidwire insertion ease

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The bending portion creates a three-dimensional pathway for wire insertion. By forming the bending portion at an angle, the wire can be inserted from the distal end along a curved path to the base portion, allowing tight holding while maintaining ease of insertion through spatial arrangement.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

An electronic component includes: a conducting wire having conductivity; and a conductive member having a bent terminal that holds an end of the conducting wire. The bent terminal includes: a base portion that supports the conducting wire; a folding portion that is continuous from one end side of the base portion and that is bent and folded back; and a bending portion that is continuous from the folding portion and that is provided to a distal end side opposite to the base portion. The conducting wire is sandwiched between the base portion and the folding portion or the bending portion. The bending portion is bent toward a side closer to the base portion than a tangential direction of the folding portion, so that a gap between the bending portion and the base portion is smaller than a width of the conducting wire.
