Connector Heat Dissipation via Insulation Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors experience significant temperature rises due to heat generation from current flow, leading to increased costs and complexity with additional heat transfer components.
Innovation Solution
A connector design incorporating a male terminal with an insulating insulation member and a heat dissipating portion that protrudes from the terminal connection portion, allowing for efficient heat dissipation without increasing the number of components, utilizing an insulating housing and a shield member with high thermal conductivity for enhanced heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat transfer component (nut) is added to release heat from the male terminal, then heat dissipation is improved, but the number of components increases
Solution Approach 1:
The patent combines the heat dissipation function with the existing insulation member by adding a heat dissipating portion to it. This integration allows the insulation member to serve dual purposes: electrical insulation and heat dissipation, thereby eliminating the need for separate heat transfer components and reducing overall component count.
Solution Approach 2:
The insulation member is designed to perform multiple functions simultaneously. By incorporating the heat dissipating portion, the insulation member becomes a multi-functional component that provides both electrical insulation and thermal management, reducing the need for additional specialized components.
2Temperature
If additional heat transfer components are used, then temperature control is improved, but manufacturing cost increases
Solution Approach 1:
The patent merges the heat dissipation function into the existing insulation member structure. This consolidation reduces the total number of parts that need to be manufactured, assembled, and managed, thereby lowering manufacturing costs while maintaining effective temperature control.
Solution Approach 2:
By making the insulation member multi-functional (providing both insulation and heat dissipation), the patent eliminates the need for separate heat transfer components, reducing bill of materials costs, assembly costs, and overall manufacturing complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The connector effectively suppresses temperature rises by dissipating heat through the insulation member and shield member, reducing the need for additional components and improving thermal management while maintaining electrical insulation.
Implementation Method 1
at least one heat dissipating portion which is a portion protruding from the shaft portion toward an outside of the terminal connection portion in a direction intersecting a cylinder axis of the terminal connection portion, and is capable of dissipating heat at the outside of the terminal connection portion
Implementation Method 2
the heat dissipating portion is brought into contact with a portion of the connector installation target having a higher thermal conductivity than that of the insulation member

AI summary
Provided are: a male terminal which has an outer peripheral wall side of a tubular terminal connection portion as a contact point with a mating terminal; an insulating insulation member which is configured to achieve electrical insulation of a distal end of the terminal connection portion on a side of a mating connector; and an insulating housing which accommodates the male terminal and the insulation member.
