Joint Terminal Abutting Structure for Accurate Wire Crimp Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing joint terminals face difficulties in adjusting the protruding margin of electric wires during crimping, especially when both wires are crimped in the same direction, leading to variations and potential fraying or cutting of braided wires during conduction inspections.
Innovation Solution
A plate-shaped joint terminal with a first and second mounting portion, crimping pieces, and an abutting portion that is bent towards the thickness direction to abut against the tip end surface of the second electric wire, preventing variations in the protruding margin and allowing for accurate conduction inspections without direct contact with the braided wire.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If one electric wire is attached in a state where the other electric wire is already attached, then both wires can be crimped in the same direction, but it becomes difficult to adjust the protruding margin of the electric wire
Solution Approach 1:
The abutting portion is formed in advance by bending the end portion of the joint terminal body toward the thickness direction of the mounting portion. This preliminary structural preparation provides a reference surface that enables accurate positioning of the electric wire before crimping, allowing the protruding margin to be adjusted precisely even when both wires are crimped in the same direction.
2Productivity
If the protruding margin of the electric wire varies, then crimping can be performed, but fraying or cutting of the braided wire may occur during conduction inspections
Solution Approach 1:
The abutting portion acts as an intermediary reference surface between the mounting portion and the tip end surface of the electric wire. By providing this intermediate abutting surface, the invention ensures consistent positioning and protruding margin without variation, preventing fraying or cutting during conduction inspections while maintaining crimping process continuity.
