Wire-Fixing Connector Assembly for Stable Contact in Tight Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The miniaturization of electronic devices leads to reduced plugging or installation space for header connectors, causing wire pulling and deflection, resulting in poor electrical contact, arcing, accidental contact, and signal interference between adjacent wires.
Innovation Solution
A connector assembly with a wire fixing unit that includes a base, side wings, and a wire unit, where the side wings have fixing portions that clamp second fixing portions of a wire fixing unit, engaging through holes to stabilize the wires and maintain distance between them, preventing deflection and interference.

Engineering Contradiction Analysis
1Volume of moving object
If the plugging space is reduced due to miniaturization, then the device size is reduced, but the wires are pulled causing poor electrical contact
Solution Approach 1:
The connector is divided into a base and a wire fixing unit that can be assembled separately. The wire fixing unit is first combined with the flat cable, then the base is rotatably connected to form the complete connector assembly, allowing wire stress to be isolated from the bonding interface
Solution Approach 2:
The wire fixing unit acts as an intermediary component between the flat cable and the base. It includes fixing portions that clamp the wires and through holes that guide wire positioning, thereby protecting the wire-base bonding interface from stress and deflection
2Volume of moving object
If the plugging space is reduced due to miniaturization, then the device size is reduced, but wire deflection occurs causing arcing and signal interference
Solution Approach 1:
The wire fixing unit is assembled with the flat cable before the base is connected. The fixing portions are pre-positioned to clamp and align the wires, and the through holes are pre-formed to guide wire placement, preventing deflection before the connector is fully assembled
Solution Approach 2:
The wire fixing unit provides localized support and constraint to the wires through specifically designed fixing portions and through holes. This local reinforcement maintains wire spacing and alignment at critical locations without requiring overall connector enlargement

AI summary
A connector assembly includes a base, a wire unit, and a wire fixing unit. The base includes a body and two side wings. The two side wings are respectively rotatably connected to two opposite sides of the body, and each of the side wings includes a first fixing portion. The wire unit is located between the two side wings. The wire unit includes a connection seat disposed in the body, and various wires disposed in the connection seat and protruding from one side of the connection seat. The wire fixing unit includes two second fixing portions and various through holes, in which the through holes are located between the two second fixing portions, the two first fixing portions respectively clamp the two second fixing portions, and the wires correspondingly pass through the through holes.
