Sliding Wire Terminal Structure to Prevent Crimp Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing techniques for connecting a terminal to a wire require large facilities for crimping, leading to increased manufacturing costs and a risk of unintended bending of the terminal due to contact between the sandwiching and slide portions.
Innovation Solution
A terminal design featuring a sandwiching portion and a tubular slide portion with a pressurizing portion that slides to press the sandwiching portion toward the wire, while a restricting portion prevents bending by controlling the sliding direction and contact points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a tubular slide portion with pressurizing portion is used to press the sandwiching portion toward the wire, then the need for large crimping facilities is eliminated and manufacturing cost is reduced, but the sandwiching portion may be bent by contact with the slide portion before pressing occurs
Solution Approach 1:
The restricting portion is designed to prevent bending of the sandwiching portion before the pressurizing portion applies pressure. By providing this preventive structure in advance, the patent eliminates the harmful bending effect that would otherwise occur during the crimping process, thus resolving the contradiction between reduced manufacturing cost and maintained manufacturing precision.
Solution Approach 2:
The slide portion is segmented into functional regions: a restricting portion that prevents bending and a pressurizing portion that applies crushing force. This segmentation allows each portion to perform its specific function independently, enabling cost-effective manufacturing without compromising terminal precision.
2Reliability
If dies or a jig for crimping the crimping portion are used, then reliable connection is achieved, but facility investment is necessary and manufacturing cost increases
Solution Approach 1:
The patent extracts the essential crimping function from complex dies or jigs and implements it through a simplified terminal structure with an integrated slide portion. The slide portion with its restricting and pressurizing portions provides the necessary crimping action without requiring external heavy equipment, thus maintaining connection reliability while reducing manufacturing cost.
Solution Approach 2:
The terminal structure performs its own crimping operation through the slide portion mechanism, eliminating the need for separate crimping facilities. The terminal is self-sufficient in achieving reliable connection, which reduces both facility investment and manufacturing cost while maintaining connection reliability.

AI summary
A terminal to be connected to a wire is provided with a terminal body including a sandwiching portion for sandwiching the wire, and a tubular slide portion for accommodating the terminal body inside, the slide portion being slidable with respect to the terminal body. The slide portion includes a wide portion located on a front side in a sliding direction of the slide portion and a narrow portion located behind the wide portion in the sliding direction, an inner shape of the slide portion being narrower in the narrow portion than in the wide portion. The narrow portion is provided with a pressurizing portion projecting inwardly of the slide portion. The pressurizing portion presses the sandwiching portion toward the wire with the slide portion 16 slid in the sliding direction with respect to the terminal body and the narrow portion located outside the sandwiching portion.
