Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors face challenges in effectively dissipating heat generated by power source terminals, which can lead to accumulation and reduced performance in electronic devices.
Innovation Solution
The connector design includes a socket and header with specific terminal configurations and holder brackets made of metal, featuring oblong rectangular shapes and tapered parts, which enhance heat dissipation by increasing the surface area for thermal management and mechanical strength, allowing for efficient electrical connections and reliable terminal engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional connector designs are used, then the structure is simple, but heat dissipation capability is insufficient
Solution Approach 1:
The patent extends the holder bracket in the longitudinal direction to create tapered parts that protrude beyond terminal ends. This dimensional extension adds heat dissipation surface area without significantly increasing overall connector complexity, as the extension is integrated into the existing holder bracket structure rather than adding separate components.
Solution Approach 2:
The holder bracket is segmented into multiple functional zones: a body portion for structural support, extended portions for heat dissipation, and locking portions for terminal engagement. This segmentation allows each zone to perform its specific function optimally while maintaining overall structural integrity.
2Reliability
If terminal engagement force is increased, then connection reliability is improved, but friction and heat generation increase
Solution Approach 1:
The locking portion is designed to dynamically adapt during engagement: initially flexible to guide terminal insertion with minimal friction, then transforming into a rigid locked state that provides strong mechanical interlocking. This dynamic behavior reduces initial friction during insertion while maintaining high reliability in the engaged state.
Solution Approach 2:
The tapered parts feature curved surfaces that guide terminal engagement smoothly, reducing friction compared to sharp angular contacts. The curvature distributes contact forces more evenly, lowering peak friction and heat generation while maintaining reliable connection.
3Temperature
If metal holder brackets with extended portions are used, then heat dissipation surface area is increased, but manufacturing complexity increases
Solution Approach 1:
The heat dissipation extended portions are merged with the holder bracket body as an integrated structure rather than separate components. This allows the holder bracket to simultaneously perform structural support, terminal retention, and heat dissipation functions, reducing manufacturing steps and assembly complexity while maximizing heat dissipation surface area.

AI summary
A connector is configured such that, while a socket housing (31) is engaged with a header housing (21), a socket-side signal terminal (32) contacts a header-side signal terminal (22), and a socket-side power source terminal (33) contacts a header-side power source terminal (23). A socket-side holder bracket (34) is disposed in the socket housing (31). The socket-side holder bracket (34) includes a mounting terminal (34d) configured to be soldered to a circuit pattern formed on a circuit board (60). The socket-side power source terminal (33) includes a base part (33a) configured to be soldered to the circuit pattern formed on the circuit board (60). The mounting terminal (34d) and the base part (33a) are soldered to a common circuit pattern.
