Rotary Cable Coupler for Insulation Piercing Connector Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional insulation piercing connectors require individual signal lines to be inserted and pierced manually, leading to laborious assembly processes and higher defective rates due to human error.
Innovation Solution
A rotary cable coupler is integrated with the insulation piercing connector, allowing simultaneous insertion and piercing of multiple signal lines, reducing human error and assembly time through a rotary mechanism with piercing members and plug holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If individual signal lines are inserted and pierced manually one by one, then the insulation piercing connector can be assembled, but the assembly process becomes laborious and time-consuming with higher defective rates
Solution Approach 1:
The patent combines multiple piercing members and plug holes into a single integrated rotary cable coupler assembly, allowing multiple signal lines to be inserted and pierced simultaneously through one rotational operation, thereby merging multiple manual operations into a single automated action
Solution Approach 2:
The rotary cable coupler introduces rotational motion to dynamically position the plug holes and piercing members, enabling the assembly mechanism to progress through different angular positions to accommodate multiple signal lines sequentially in a single continuous operation
2Ease of operation
If individual signal lines are inserted and pierced manually one by one, then the insulation piercing connector can be assembled, but human error increases and defective rate rises
Solution Approach 1:
The rotary cable coupler design allows the signal lines to be automatically positioned and pierced through the rotational mechanism, reducing reliance on manual dexterity and human judgment, thereby minimizing human error and improving assembly consistency
Solution Approach 2:
The patent replaces manual mechanical insertion and piercing operations with an automated rotary mechanism that mechanically guides and positions the signal lines, substituting human manual operations with a controlled mechanical system
3Productivity
If a rotary cable coupler is used to insert and pierce multiple signal lines simultaneously, then assembly efficiency improves and working hours reduce, but the device complexity increases
Solution Approach 1:
The rotary cable coupler serves multiple functions simultaneously: it holds multiple plug holes for signal line insertion, provides rotational positioning, and houses multiple piercing members, thereby consolidating multiple components into a single multi-functional element that reduces overall device complexity despite increased capability

AI summary
A wiring structure improvement of an insulation piercing connector for electrical connection after plural signal lines (40) being inserted includes a connector body (1), plural terminals (2) disposed in the connector body (1), and a rotary cable coupler (3). The connector body (1) has a wiring end (11). Each of the terminals (2) has a terminal body (20) and a piercing member (21) formed at one end of the terminal body (20) and disposed at the wiring end (11). The rotary cable coupler (3) is sleeved around the wiring end (11) and has plural plug holes (30) corresponding to the piercing members (21). Thus, when the rotary cable coupler (3) is rotated, the signal lines (40) are pushed by the plug holes (30) towards the piercing members (21) correspondingly such that the piercing members (21) pierce the signal lines (40) for the electrical connection.
