Plug Connector With Insulation-Displacement Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plug connectors require complex assembly processes and increased operation costs due to the need for rapid cooling of soldered connections, and they tend to be longer due to insulation-displacement connector (IDC) designs that require additional space for piercing wires, hindering downsizing efforts.
Innovation Solution
A plug connector with an insulative body, housing, and terminals that uses insulation-displacement connection and a holding block with guiding grooves and IDC grooves to connect electrical conductors without the need for extensive space, allowing for easier assembly and potential downsizing by screwing up inner and outer threads for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If soldering method is used to connect contact terminals to signal wires, then electrical connection is achieved, but assembly process becomes complex and operation costs increase due to rapid cooling requirement
Solution Approach 1:
The patent replaces the thermal soldering process with a mechanical insulation displacement connection. The terminal directly pierces and mechanically engages with the signal wire within the insulation layer, eliminating the need for molten solder, cooling processes, and associated complex assembly steps while maintaining reliable electrical connection.
2Productivity
If insulation-displacement connector (IDC) with punching work is used, then wiring efficiency is improved, but connector length increases due to required upper space for piercing wires
Solution Approach 1:
The patent repositions the insulation displacement piercing action from a vertical upward direction (requiring upper space) to a horizontal lateral direction within the terminal's body. The terminal pierces the signal wire sideways through its insulation layer, eliminating the need for extended upper space and reducing overall connector length while maintaining wiring efficiency.

AI summary
A plug connector includes an insulative body, a housing and a plurality of terminals, and electrically connects to an electrical cable in a manner of insulation-displacement. The insulative body defines a top piece having an external thread of a first screw portion in one end, and defines a plurality of inserting grooves disposed with the terminals. The housing defines an interior space communicating with the inserting grooves, and defines an inner thread of a second screw portion in one end. The interior space accommodates a holding block remaining an electrical conductor of the electrical cable bent out. The housing connects the insulative body with the inner thread to the external thread.
