Shear Guide for Terminal Crimping Machine Wire Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Positioning and maintaining the correct alignment of magnet wires and lead wires within an open barrel terminal during the crimping process is challenging, which can compromise the electrical connection and the functionality of the associated electrical device.
Innovation Solution
A shear guide is designed for a terminal crimping machine, featuring magnet wire channels and lead wire channels that are vertically and horizontally offset to securely hold and position the wires relative to the electrical terminal, ensuring proper alignment and stability during the crimping process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnet wires are positioned along the bottom of the open barrel terminal to engage the serrations, then electrical connection is established, but positioning the magnet wires efficiently and correctly relative to the terminal and lead wires is challenging
Solution Approach 1:
The shear guide is divided into separate channels for magnet wires and lead wires, with each channel providing dedicated positioning features. The magnet wire channel includes bottom and side walls that form distinct positioning zones, separating the positioning functions for different wire types to enable efficient and correct positioning.
Solution Approach 2:
The shear guide acts as an intermediary device between the wire loading process and the crimping operation. It provides a structured environment with channels and positioning walls that guide wires into correct positions before they enter the terminal, making the positioning process easier and more reliable.
2Reliability
If magnet wires are positioned correctly to engage serrations, then electrical connection is established, but ensuring that the positions of the wires remain unchanged during the crimping process is problematic
Solution Approach 1:
The shear guide pre-positions the magnet wires and lead wires in their correct final positions within dedicated channels before the crimping operation begins. The channels with bottom and side walls lock the wires in place, preventing position changes during the subsequent crimping process.
Solution Approach 2:
Different regions of the shear guide provide different positioning characteristics tailored to specific wire types. The magnet wire channel has bottom and side walls configured for magnet wire positioning, while the lead wire channel has separate positioning features, ensuring each wire type maintains its position appropriately during crimping.
3Productivity
If multiple wires are loaded into the terminal, then electrical connections can be established, but positioning the wires efficiently and correctly relative to each other and the terminal is challenging
Solution Approach 1:
The shear guide segments the wire loading process into distinct channels for magnet wires and lead wires. Each channel provides dedicated positioning walls that guide multiple wires simultaneously into correct positions, making it easier to load and position multiple wires efficiently and correctly relative to each other and the terminal.

AI summary
A shear guide for a terminal crimping machine includes a body having a shear edge configured to face a terminal used to splice a magnet wire and a lead wire. A magnet wire channel is formed by the body and is configured to receive and hold the magnet wire. A lead wire channel is formed by the body and is configured to receive and hold the lead wire. The lead wire channel is vertically offset with respect to the magnet wire channel. The body may include a platform and a separating wall positioned vertically above the platform with a slot defined between the separating wall and the platform. The slot may receive the magnet wire and the separating wall may support the lead wire above the separating wall.
