Electric Connector Housing With Guide Holes for Thin-Wire Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric connectors face difficulties in reliably inserting and fixing multiple electric wires into through holes as the number of wires increases and wire diameters decrease, leading to insertion challenges.
Innovation Solution
The electric connector design incorporates a housing with guide portions that support and direct electric wires into holding holes, ensuring reliable insertion, with features like grooves and tapers for easier alignment and visibility enhancements, and a staircase-like configuration to manage multiple guide portions efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of electric wires is increased and wire diameter is reduced, then the connector can handle more signals with smaller size, but the difficulty of inserting wires into through holes increases
Solution Approach 1:
The guide portions are formed in advance within the housing to create a predetermined path for wire insertion. This preliminary structural preparation guides the wires before they reach the holding holes, making the insertion process easier even when dealing with many thin wires.
Solution Approach 2:
The guide portions act as an intermediary structure between the wire insertion point and the holding holes. These guide portions provide a transitional path that facilitates the movement of wires from the external environment into the confined holding holes, reducing the direct difficulty of insertion.
2Quantity of substance
If the number of electric wires is increased and wire diameter is reduced, then the connector capacity increases, but the reliability of fixing wires deteriorates
Solution Approach 1:
The guide portions are formed in advance within the housing to create a predetermined path for wire insertion. This preliminary structural preparation guides the wires before they reach the holding holes, making the insertion process easier even when dealing with many thin wires.
Solution Approach 2:
The guide portions provide localized structural features at specific locations within the housing that are optimized for wire guidance. Each guide portion is positioned and shaped to match the specific requirements of its corresponding holding hole, ensuring reliable fixing for each individual wire path.
3Reliability
If guide portions are added to support and direct wires, then insertion reliability improves, but the connector size and structural complexity increase
Solution Approach 1:
The guide portions are merged with the housing structure itself, forming an integrated component rather than separate add-on elements. This combining of functions reduces the number of discrete parts and simplifies the overall structure while still providing the necessary wire guidance functionality.
Solution Approach 2:
The housing structure serves multiple functions: it provides mechanical support, contains the holding holes, and incorporates the guide portions for wire direction. This multi-functionality reduces the need for separate dedicated guide components, thereby reducing overall structural complexity.

AI summary
An electric connector includes a plurality of first electric wires each extending along a first direction and arranged side by side, and a housing including a plurality of first holding holes each extending and penetrating along the first direction and arranged side by side. A conductor of a tip portion of each of the plurality of first electric wires is housed in each of the plurality of first holding holes. The plurality of first holding holes hold the plurality of first electric wires such that the tips of the plurality of first electric wires are exposed on the front surface of the housing. The housing is provided with a first guide portion configured to, while supporting the plurality of first electric wires, introduce each of the plurality of first electric wires into each of the plurality of first holding holes toward the front surface of the housing.
