Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing plug connector technology faces inefficiencies in attaching substrates due to time-consuming soldering processes, potential bridging issues, and malfunctions caused by flux interference, leading to reduced yield and increased discarding of connectors.
Innovation Solution
A plug connector design featuring a slider mechanism that allows for the substrates to be inserted without initial contact with the lead contact parts, using a slider to position the contactors correctly and apply a controlled pressing force, eliminating the need for soldering and reducing the risk of bridging and flux interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If soldering is used to fix the lead contact part and electrode pad, then connection strength is improved, but manufacturing time increases significantly
Solution Approach 1:
The patent replaces the soldering process (thermal/chemical joining) with a mechanical pressing system. The pressing device applies controlled force to press the lead contact part against the electrode pad, creating an electrical connection without soldering. This substitution eliminates the time-consuming soldering steps while maintaining connection reliability through precise mechanical force control.
2Adaptability or versatility
If multi-poled type plug connector with narrow pitch is used, then device integration is improved, but bridging between adjacent contactors occurs
Solution Approach 1:
The patent implements local quality control by applying pressing force individually to each lead contact part through separate pressing elements. This localized pressing approach ensures that each contactor is pressed independently without affecting adjacent contactors, preventing bridging even when pitch is narrow. The pressing device can control the force distribution locally at each contact point.
3Manufacturing precision
If soldering work is performed manually, then connection precision is improved, but productivity decreases
Solution Approach 1:
The patent employs a self-service pressing mechanism where the pressing device automatically positions and applies force to each lead contact part without requiring manual intervention for each connection. The device can process multiple contactors systematically, providing consistent pressing force and alignment automatically. This automation maintains connection precision while dramatically improving productivity compared to manual soldering.
4Ease of manufacture
If flux liquid is used for soldering, then soldering process is facilitated, but malfunctions occur due to flux interference
Solution Approach 1:
The patent extracts and eliminates the flux liquid step from the manufacturing process by using mechanical pressing instead of soldering. Since no soldering is performed, flux liquid is not required, and the risk of flux interference with electrical connections is completely removed. The pressing process achieves reliable electrical connections through direct mechanical contact and force application.

AI summary
Problem to be Solved: The present invention provides a plug connector that can improve the efficiency of attaching work of a substrate, and improve the yield. Means for Solving the Problem: A plug connector 10 includes a substrate 40, an insulator 50, a slider 60, and a contactor 80. The slider 60 is slidable between positions 90 and 91 inside the insulator 50. The contactor 80 is housed between an inner surface of a housing space part 65 of the slider 60 and a substrate receiver part 62. The substrate receiver part 62 fixes the lead contact part 87 of the contactor 80 to a position apart from an electrode pad 41 of the substrate 40 in a state where the slider 60 is located at the position 90 or fixes to a position where a pressing force of the lead contact part 87 against the electrode pad 41 is limited to not greater than a predetermined value, and releases fixation of the position when the slider 60 is moved from the position 90 to the position 91. The slider 60 presses the lead contact part 87 against the electrode pad 41 by pressing the contactor 80 when sliding.
