Movable IDC Connector Assembly for Strip-Free Cable Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional method of connecting LED lighting units requires stripping off parts of the sheath and insulators from cables, which decreases working efficiency.
Innovation Solution
A connector combined body comprising a cable side connector with movable parts and insulation displacement contacts that allow direct contact with conductors without stripping, and a board side connector for easy electrical connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the conventional cable connection method is used, then the electrical connection between LED lighting units can be established, but the worker needs to strip off parts of the sheath and insulators which decreases working efficiency
Solution Approach 1:
The patent introduces a connector as an intermediary device between the cable and the LED lighting unit terminal block. The connector includes a body with contact pieces that directly contact the conductors, and a movable part that can be pressed to establish electrical connection without stripping the cable insulation. This intermediary device solves the contradiction by providing both automated contact establishment (improving productivity) and simplified operation (improving ease of operation).
Solution Approach 2:
The patent replaces the manual mechanical stripping operation with a mechanical pressing action on the movable part of the connector. Instead of requiring workers to manually strip insulation and insert conductors, the movable part is pressed to automatically establish electrical contact through the contact pieces, substituting complex manual mechanical operations with a simple pressing motion that improves both efficiency and ease of operation.
2Productivity
If the manual stripping method is used, then the conductors can be exposed and connected to the terminal block, but the process is time-consuming and reduces productivity
Solution Approach 1:
The connector is segmented into distinct functional parts: a body containing the contact pieces, and a movable part that actuates the connection. This segmentation allows each part to perform its specific function efficiently - the contact pieces make electrical contact while the movable part provides the actuation mechanism - thereby achieving fast connection speed without requiring overly complex integrated structures.
Solution Approach 2:
The connector incorporates a movable part that transitions from a non-contacting state to a contacting state when pressed. This dynamic element allows the connector to adapt its configuration during operation, enabling fast connection establishment through simple pressing while maintaining a compact and relatively simple overall structure when not in use.

AI summary
A connector combined body includes a cable side connector and a board side connector electrically connected and mated with the cable side connector. The cable side connector includes a main body part, a movable part connected to the main body part, and a first compound contact disposed in the main body part. The movable part is movable in one direction into the main body part and has a retaining portion in which a cable is inserted and retained. The cable includes a plurality of conductors, a plurality of insulators each separately surrounding one of the conductors, and a sheath surrounding the insulators. A first end side of the first compound contact is an insulation displacement contact. A movement of the movable part in the one direction pushes the insulation displacement contact into contact with the conductors of the cable.
