Solution Overview

Problem

Current electrical connectors struggle to meet the increasing speed requirements of chip modules, leading to signal errors and assembly difficulties due to their miniaturization and dense terminal configurations, which result in poor high-frequency characteristics and interference.

Innovation Solution

The design incorporates fixing grooves to securely connect first and second terminals, increasing the volume of conductive terminals and reducing interference, with features like elastic arms and specific groove configurations to enhance assembly accuracy and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If terminals are made smaller in thickness and volume to meet miniaturization requirements, then the electrical connector can satisfy miniaturization requirements, but assembly becomes difficult and interference easily occurs due to dense terminals

Engineering Contradiction:
Improveterminal volumeVSAvoidassembly difficulty
Core Design Contradiction:
Volume of moving objectVSEase of manufacture

Solution Approach 1:

The terminal is divided into two independently provided terminals: a first terminal with a first connecting portion and an elastic arm, and a second terminal with a second connecting portion and a conducting portion. This segmentation allows each terminal to be optimized separately while maintaining overall miniaturization, and the independent structure facilitates easier assembly compared to a single integrated terminal.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first terminal and second terminal are mated and fixed along a vertical direction, with the first connecting portion and second connecting portion nested together. This nesting arrangement reduces the overall horizontal space required for each terminal, allowing denser terminal arrangements without increasing interference, while the vertical mating provides stable assembly.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Quantity of substance

If terminals are arranged densely to increase connection quantity, then more connections can be made in limited space, but interference easily occurs resulting in poor high-frequency characteristics

Engineering Contradiction:
Improveterminal quantityVSAvoidhigh-frequency characteristics
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The first terminal and second terminal are arranged along a vertical direction rather than horizontally adjacent to each other. This vertical arrangement utilizes the third dimension (height) to accommodate multiple terminals, allowing increased terminal quantity without increasing horizontal density. The vertical separation reduces electromagnetic interference between adjacent terminals, maintaining good high-frequency characteristics even with increased terminal quantity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If terminal volume is increased to improve high-frequency characteristics, then interference between terminals is reduced, but the connector size increases

Engineering Contradiction:
Improvehigh-frequency characteristicsVSAvoidconnector size
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The terminal structure utilizes vertical arrangement along the Z-axis to provide sufficient volume for each terminal without increasing the horizontal footprint (X-Y plane dimensions). By extending the terminal structure in the vertical dimension rather than expanding horizontally, the connector maintains compact overall size while each terminal has adequate volume to reduce interference and improve high-frequency characteristics.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

An electrical connector, used for electrically connecting a chip module to a circuit board, includes: an insulating body, provided with multiple accommodating grooves penetrating through the insulating body; and multiple conductive terminals, correspondingly accommodated in the accommodating grooves. Each conductive terminal includes a first terminal and a second terminal independently provided. The first terminal has a first connecting portion and an elastic arm, and the elastic arm has a contact portion to be in contact with the chip module. The second terminal has a second connecting portion and a conducting portion to be electrically connected with the circuit board. At least one fixing groove is provided on at least one of the first connecting portion and the second connecting portion, and the first terminal and the second terminal are mated and fixed along a vertical direction by the at least one fixing groove.
