Terminal Insertion Device Bundling Connector Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing terminal insertion devices require significant separation of electric wires in multi-core cables to insert connector terminals into a connector housing, which increases the separation length and can lead to unsteadiness during insertion.
Innovation Solution
A terminal insertion device with a terminal separator and chuck mechanism that bundles and clamps connector terminals in specific directions, allowing them to be inserted into terminal accommodating chambers in a one-to-one manner, reducing the need for individual wire separation and ensuring stable insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electric wires are held individually near connector terminals using conventional electric wire chuck device, then each connector terminal can be inserted into terminal accommodating chamber, but significant separation length of electric wires is required and insertion stability deteriorates
Solution Approach 1:
The invention separates the holding function into two distinct components: the terminal separator holds the connector terminals in a bundled state with tips allocated to inlets in a one-to-one manner, while the electric wire chuck device holds the electric wires. This segmentation allows the connector terminals to be held collectively rather than individually, reducing the required separation length while maintaining insertion stability.
Solution Approach 2:
The terminal separator acts as an intermediary component between the connector terminals and the holding mechanism. It is configured to hold the connector terminals so that their tips are allocated to the inlets of terminal accommodating chambers in a one-to-one manner, enabling stable insertion without requiring significant separation of the electric wires.
2Ease of operation
If significant separation of electric wires is performed to allow individual holding, then connector terminals can be inserted into terminal accommodating chambers, but high frequency characteristics of multi-core cable deteriorate
Solution Approach 1:
The invention divides the holding function into two parts: the terminal separator manages the connector terminals in a bundled state with proper alignment, while the electric wire chuck device manages the electric wires. This segmentation enables insertion operation without requiring significant wire separation, thereby preserving high frequency characteristics.
Solution Approach 2:
The terminal separator serves as an intermediary that enables proper allocation of connector terminal tips to inlet positions without requiring the electric wires to be separated significantly. This maintains the integrity of the multi-core cable structure and preserves high frequency characteristics.
3Length of moving object
If connector terminals are held in bundled state with tips allocated to inlets in one-to-one manner, then separation length is reduced, but alignment precision to terminal accommodating chambers must be maintained
Solution Approach 1:
The terminal separator acts as a precision intermediary component that ensures connector terminals are held with their tips allocated to the inlets of terminal accommodating chambers in a one-to-one manner. This intermediary structure maintains the required alignment precision while allowing the terminals to be held in a bundled state, thus reducing separation length.
Solution Approach 2:
The terminal separator pre-aligns the connector terminals before insertion by holding them in a bundled state with tips allocated to inlet positions. This preliminary alignment action ensures that when insertion occurs, the terminals are already positioned correctly, maintaining alignment precision without requiring significant separation.

AI summary
A terminal insertion device is provided which enables inserting connector terminals into terminal accommodating chambers of a connector housing, each of the connector terminals being connected to an end of each of a plurality of electric wires in a multi-core cable by crimping, while reducing the separation length for the plurality of electric wires. The terminal insertion device comprises: a terminal separator configured to be interposed between two connector terminals; a terminal chuck configured to clamp and bundle the two connector terminals in two directions, i.e., in a first direction intersecting an insertion direction and in a second direction intersecting the insertion direction and the first direction; and a moving mechanism configured to move at least one of a connector housing and the two connector terminals held by the terminal separator and the terminal chuck to insert the two connector terminals into two terminal accommodating chambers.
