Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Larger electrical connectors with many contacts are susceptible to damage during mating due to misalignment, leading to bent or broken male contacts.

Innovation Solution

A header connector system featuring a terminal stabilizer with a stabilizer plate and locking arms that moves between extended and retracted positions, securing terminals in place during mating and protecting them from damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If male contacts are extended into the cavity for mating, then electrical connection is enabled, but the contacts are susceptible to bending or breaking during mating due to misalignment

Engineering Contradiction:

Improvecontact integrityVSAvoidmechanical damage during mating

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The terminal stabilizer is positioned in advance within the cavity to provide preliminary support and alignment for the male contacts before mating occurs. This preliminary positioning prevents misalignment and subsequent damage during the mating process.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The terminal stabilizer acts as an intermediary component between the terminal holder and the mating connector. It provides a stable reference structure that guides the male contacts into proper alignment, preventing direct mechanical stress on the contacts during mating.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a terminal stabilizer is added to protect contacts, then contact damage is prevented, but device complexity increases

Engineering Contradiction:

Improvecontact protectionVSAvoidconnector structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The terminal stabilizer is integrated with the terminal holder as a single assembly, combining the functions of terminal support and stabilization into one unified structure. This merging reduces the number of separate components and simplifies the overall connector design.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The terminal stabilizer serves multiple functions: it provides structural support for the male contacts, ensures proper alignment during mating, and prevents mechanical damage. This multi-functionality reduces the need for additional specialized components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A header connector includes a terminal holder in a cavity of a housing that includes terminal channels between upper and lower surfaces that hold terminals with male mating ends extending from an upper surface of the terminal holder into the cavity for mating with a plug connector. A terminal stabilizer is received in the cavity coupled to the terminal holder including a stabilizer plate with terminal openings that receive the male mating ends. The terminal stabilizer is movable relative to the terminal holder between an extended position and a retracted position. Locking arms engage the support latches to hold the terminal stabilizer in the extended position and are released from the support latches to move to the retracted position. The stabilizer plate is located proximate to distal ends of the male mating ends in the extended position but is remote from the distal ends in the retracted position.
