Connector With Alternating Contacts And Insulation Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors face challenges in minimizing the arrangement pitch between female and male contacts due to insulator walls, making it difficult to achieve a narrower pitch.
Innovation Solution
The connector design features alternately arranged female and male contacts with insulation portions between them, along with aligning recesses and protrusions for precise alignment, allowing for a smaller arrangement pitch by eliminating the need for insulator walls between contacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If insulator walls are used to enclose female contacts in conventional connectors, then electrical insulation is ensured, but the arrangement pitch between contacts increases
Solution Approach 1:
The patent extracts the insulator wall from the housing structure and repositions it as a separate insulation portion between contacts. This allows the insulator to be placed only where needed for insulation rather than enclosing all contacts, thereby reducing the arrangement pitch while maintaining electrical insulation between adjacent male and female contacts.
Solution Approach 2:
The patent changes the dimensional arrangement by placing insulation portions selectively between specific contacts in the arrangement direction rather than using continuous insulator walls. This selective placement in one dimension allows for reduced pitch while maintaining insulation where required.
2Stability of the object's composition
If female contacts are fully enclosed by housing, then contact protection is achieved, but alignment precision between connectors decreases
Solution Approach 1:
The patent introduces asymmetric features (aligning protrusions and recesses) at specific locations of the connectors. These asymmetric alignment features guide precise positioning between male and female contacts during assembly, compensating for the reduced enclosure protection while improving alignment precision.
Solution Approach 2:
The patent segments the housing structure to provide localized protection rather than full enclosure. The housing protects contacts from lateral directions while leaving the arrangement direction open for alignment features, achieving both protection and precision alignment through segmented design.

AI summary
A connector includes a first connector having first female contacts, first male contacts and a first insulation portion disposed between each first female contact and an adjacent first male contact, and a second connector having second female contacts, second male contacts and a second insulation portion disposed between each second female contact and an adjacent second male contact, provided that a width of each first female contact and second female contact on fitting is denoted by W1, a width of the first insulation portion and the second insulation potion by W2, and a width of each first male contact and second male contact by W3, a distance between centers of one first female contact and an adjacent first male contact and a distance between centers of one second female contact and an adjacent second male contact are each smaller than a sum of W1/2, W2 and W3/2.
