Ribbon Cable Connector Structure for PCB Without Soldering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ribbon cable connectors require a soldering process for connection to a printed circuit board (PCB), leading to increased labor costs and inefficiencies in manufacturing and repair, as they can only be disconnected and reconnected through soldering.
Innovation Solution
A simple connector structure featuring a connecting body with accommodating spaces for the PCB and ribbon cable, equipped with conductive terminals and protruding parts for secure electrical contact and fastening, along with a fixture element for easy attachment and detachment, allowing for quick connection and disconnection without soldering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a soldering process is used to connect the connector to the PCB, then reliable electrical connection is achieved, but labor costs and manufacturing complexity increase
Solution Approach 1:
The patent replaces the soldering process (thermal/chemical system) with a mechanical pressing system. The connecting body is pressed onto the PCB, causing the conductive terminal to deform elastically and form an interference fit with the through-hole, achieving reliable electrical connection without soldering
Solution Approach 2:
The patent utilizes elastic deformation of the conductive terminal as a parameter change mechanism. The terminal is designed to deform elastically during pressing, expanding to engage with the through-hole wall, and maintaining constant contact pressure to ensure reliable electrical connection
2Reliability
If a soldering process is used to connect the connector to the PCB, then stable electrical connection is achieved, but disconnection and repair become difficult
Solution Approach 1:
The patent creates a dynamic, reversible mechanical connection instead of a static soldered joint. The connecting body can be easily pressed off the PCB by applying force in the opposite direction, allowing for simple disconnection and repair operations while maintaining stable electrical connection during normal use
3Ease of operation
If a clamshell connector with flip cover is used, then the ribbon cable can be fixed and released, but the structure becomes complex and requires multiple components
Solution Approach 1:
The patent merges the functions of the clamshell connector body, conductive terminal, and fastening mechanism into a single integrated connecting body. The pressing operation simultaneously achieves electrical connection and mechanical fastening, eliminating the need for separate flip covers and multiple components

AI summary
A simple connector structure includes a connecting body. The connecting body has a first accommodating space and a second accommodating space. The first accommodating space is matched with a PCB, and the second accommodating space is matched with a ribbon cable body. In addition, the first accommodating space is provided with at least one first conductive part, and the second accommodating space is provided with at least one second conductive part. Therefore, quick connection and labor cost reduction can be effectively achieved through connecting the first accommodating space with the PCB and connecting the second accommodating space with the ribbon cable body.
