Solution Overview
Problem
Conducting pins in compressing contact electrical connectors made from general metal materials become deformed and lose flexibility after repeated use, leading to poor contact between electronic elements and affecting the connector's functionality.
Innovation Solution
The electrical connector features a flexible body with a metal layer on the outside, including a positioning mechanism and angled contacting points to ensure firm contact and reduce deformation, along with a gold layer for improved conductivity and resistance, and optional openings in the metal layer to prevent chapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conducting pins are made from general metal material, then electrical conductivity is achieved, but the conducting pin becomes deformed and loses flexibility after repeated compression
Solution Approach 1:
The conducting pin is constructed as a composite structure with an inner core (providing structural stability) and an outer metal layer (providing conductivity and flexibility). This composite design allows the pin to maintain both electrical conductivity and flexibility after repeated compression, resolving the contradiction between reliability and compositional stability.
2Reliability
If conducting pins are made from general metal material, then electrical conductivity is achieved, but the manufacturing process becomes difficult due to complex shape requirements
Solution Approach 1:
The composite structure with inner core and outer metal layer simplifies manufacturing compared to forming complex shapes from solid metal. The layered construction allows for easier fabrication processes while achieving the required electrical connection reliability.
3Reliability
If the conducting body is compressed to ensure contact, then electrical connection is improved, but the metal layer develops chaps and deforms
Solution Approach 1:
The composite structure with inner core and outer metal layer allows the conducting body to compress and deform elastically without the metal layer developing chaps. The inner core provides structural support that prevents excessive deformation of the outer metal layer, maintaining contact firmness while preventing metal chapping.
Solution Approach 2:
The patent introduces an angled configuration (non-vertical alignment) of the conducting body, which changes the mechanical parameters of compression. This angular design allows the conducting body to oscillate and distribute compression forces, reducing stress concentration that would otherwise cause metal chapping while maintaining effective electrical contact.
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 flexible conducting body maintains contact reliability and prevents deformation, ensuring stable electrical connection between the chip module and circuit board while avoiding metal chapping, thus enhancing the connector's durability and performance.
Implementation Method 1
The conducting body includes a flexible body and a metal layer located on the outside of the flexible body. Because the conducting body of the electrical connector includes a flexible body and a metal layer located on the outside of the flexible body, the flexibility of the conducting body is assured.
Implementation Method 2
The external metal layer makes the chip module electrically connect with the circuit board. The metal layer has at least one opening and the metal layer forms a conducting path.
Implementation Method 3
When the conducting body is compressed, the conducting body can deform and oscillates to reduce the force imposed on the contacting points. Two contacting points are located on the conducting body that individually protrude to the upper surface and the lower surface of the insulating body, and a line connected between the two contacting points and the upper surface of the insulating body has an angle.
