Connector Wire Insertion Force Transmission Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire connectors require complex operations, making one-handed connection difficult due to the need to pull a rod-like operation button while maintaining a wire insertion state, which complicates the connection process and increases the time required.
Innovation Solution
A connector design featuring a case with a conductive terminal, an elastic member that clamps the wire, and a state maintaining part that transitions from a non-connected to a connected state when a wire is inserted, allowing direct force transmission to move the elastic member and facilitate connection without manual operation of the button.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rod-like operation button is used to maintain the open state of the flat spring, then the wire connection can be established, but the operation becomes complex and time-consuming
Solution Approach 1:
The invention extracts the operation button from the housing, allowing it to be freely movable rather than constrained. This enables the button to be manipulated independently to release the retaining groove, simplifying the wire insertion process by eliminating the need for complex coordinated operations
Solution Approach 2:
Instead of requiring the user to actively manipulate the button to maintain the open state, the invention inverts the logic: the button automatically returns to its original position through elastic restoration, and the wire insertion itself triggers the state transition. This passive mechanism reduces operational complexity
2Ease of operation
If the operation button must be pulled out while maintaining wire insertion state, then connection is achieved, but one-handed operation becomes difficult
Solution Approach 1:
The invention merges the wire insertion action with the button operation. The wire pushing against the first contact portion simultaneously triggers the button movement and the elastic member restoration, combining multiple functions into a single intuitive motion that can be performed with one hand
Solution Approach 2:
The system performs self-service through automatic state transitions. The elastic member automatically restores when the retaining groove is released, and the button automatically returns to its original position, eliminating the need for manual coordination of multiple actions

Function Achieved in This Case
This design simplifies the connection process by allowing the wire to be inserted while the connector automatically transitions to the connected state, reducing the effort and time needed for connection and enabling one-handed operation.

AI summary
A connector (1) includes a case (2), a terminal part (3), an elastic member (4), and an operation part (5). The terminal part (3) has conductivity and is fixed to the case (2). The elastic member (4) is mounted on the case (2). The elastic member (4) presses a wire (91) against and clamps the wire to the terminal part (3) by restoring force of the elastic member. The operation part (5) comes in contact with the elastic member (4) and maintains a non-connected state of the elastic member (4) in which the elastic member is bent more than in its connected state in which the elastic member clamps the wire (91). In the connector (1), when the wire (91) is inserted between the terminal part (3) and the elastic member (4) in the non-connected state, a force is transmitted indirectly from the wire (91) to the operation part (5) to move the operation part (5) and to cause the elastic member (4) to transition from the non-connected state to the connected state. This facilitates connecting the wire (91) to the connector (1).
