Thin Connector With Orthogonal Displacement For Narrow Pitch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional substrate-to-substrate connectors face challenges in narrowing the arrangement pitch while maintaining reliable electrical connections, as the displacement of receptacle contacts to prevent short-circuiting requires a large pitch.
Innovation Solution
A thin connector design featuring a first connector portion with arrayed first contacts and a second connector portion with arrayed second contacts, where the first contacts have a movable portion with spring properties in the direction of the array and a second movable portion with spring properties orthogonal to the array, allowing for a smaller displacement in the array direction and improved reliability through a unique sliding mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the main arm portion of receptacle contacts is designed to largely displace to improve connection reliability, then the reliability of connection is improved, but the arrangement pitch must be large to prevent short-circuiting
Solution Approach 1:
The receptacle contact is divided into two separate movable portions: a first movable portion that displaces in the arrangement direction and a second movable portion that displaces in the orthogonal direction. This segmentation allows each portion to have optimized displacement characteristics, enabling narrow pitch while maintaining connection reliability.
Solution Approach 2:
The invention introduces displacement in a direction orthogonal to the arrangement direction (second movable portion), adding a dimensional degree of freedom to the contact mechanism. This allows the contact to achieve reliable electrical connection through orthogonal displacement while the first movable portion handles only minimal displacement in the arrangement direction, enabling narrower pitch.
2Volume of moving object
If the arrangement pitch is narrowed to improve connector compactness, then the connector size is reduced, but the connection reliability deteriorates due to insufficient displacement of receptacle contacts
Solution Approach 1:
By segmenting the contact into two movable portions with different displacement directions, the invention enables narrow pitch design while maintaining adequate displacement for reliable connection through the orthogonal component.
Solution Approach 2:
The orthogonal displacement component (second movable portion) provides the necessary displacement for reliable electrical connection without requiring increased pitch in the arrangement direction, enabling compact connector design.
3Reliability
If the main arm portion is made flexible to improve connection reliability, then the connection reliability is improved, but the risk of adjacent contacts short-circuiting increases
Solution Approach 1:
The invention applies different displacement characteristics to different portions of the contact structure. The first movable portion has limited displacement in the arrangement direction to prevent short-circuiting, while the second movable portion provides adequate displacement in the orthogonal direction for reliable connection, achieving local optimization of both safety and reliability.
Solution Approach 2:
By redirecting the primary displacement to the orthogonal direction through the second movable portion, the invention reduces the displacement in the arrangement direction that could cause short-circuiting, while maintaining connection reliability through the orthogonal component.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enables a narrower arrangement pitch while ensuring reliable electrical connections by allowing the second movable portion to displace more than the first movable portion, enhancing the connector's reliability and efficiency.
Implementation Method 1
each of the plurality of first contacts includes a first movable portion having spring properties so as to be displaceable in the direction in which the plurality of first contacts are arrayed and a second movable portion being connected to the first movable portion, having spring properties so as to be displaceable in a direction orthogonal to the direction in which the plurality of first contacts are arrayed
