Rotating Handle Wire Connector With Stable Gap Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire connectors require continuous force application to insert or remove wires, increasing operational complexity due to the need to maintain a gap for wire insertion and removal.
Innovation Solution
An operable wire connector design featuring an insulating housing with a rotating handle, a transmitting piece, an elastic clamping piece, and a rotation limiting portion, allowing the handle to apply a pressing force to the clamping piece to create an adjustable gap for wire insertion and automatic clamping, eliminating the need for continuous force application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user continuously applies force to the operation button to maintain the gap for wire insertion, then the wire can be inserted or removed, but the operational complexity increases
Solution Approach 1:
The elastic clamping piece automatically maintains the gap between the wire and electric conductor through its elastic restoring force, eliminating the need for continuous user force application. The system serves itself by using the elastic deformation and recovery of the clamping piece to keep the wire access hole open during insertion and clamping operations.
Solution Approach 2:
The operating handle is designed to rotate between two positions: a first position where the transmitting piece presses the elastic clamping piece to open the gap, and a second position where the clamping piece returns to its original state to clamp the wire. This dynamic switching mechanism allows the user to operate the connector by simply rotating the handle rather than continuously applying force.
2Ease of operation
If the operating handle rotates freely, then the clamping piece can be pressed to open the gap, but the handle cannot maintain the opened state
Solution Approach 1:
The rotation limiting portion is pre-configured on the insulating housing to guide and limit the rotation of the operating handle. When the user rotates the handle to the first position, the rotation limiting portion prevents further rotation, automatically maintaining the gap-opened state without requiring continuous user input. This preliminary structural arrangement ensures the handle stays in the correct position.
Solution Approach 2:
The rotation limiting portion provides mechanical feedback to the operating handle by physically limiting its rotation range. When the handle reaches the first position, the rotation limiting portion creates a stopping point that gives the user tactile feedback that the gap is fully opened, and prevents the handle from rotating back, thereby maintaining the opened state stably.

Function Achieved in This Case
Facilitates easy wire insertion and removal without continuous force application, maintaining the gap through rotational limiting, thus simplifying the operation of connecting and disconnecting wires.
Implementation Method 1
an elastic clamping piece mounted inside the chamber, with an elastic free portion and a fixed portion... the force applying portion of the transmitting piece resists against the elastic free portion... an adjustable gap is formed between the elastic free portion and the electric conductor

AI summary
An operable wire connector comprises an insulating housing (1), an operating handle (2) rotatably mounted inside the insulating housing (1), a transmitting piece (3), an electric conductor (4), an elastic clamping piece (5) with a fixed portion (51) connected to the electric conductor (4) and an elastic free portion (52) resisted by the transmitting piece (3), and a cover (6) assembled with the insulating housing (1); an adjustable gap is formed between the elastic free portion (52) and the electric conductor (4) for receiving a wire, and the gap will continuously be present due to the action of a rotation limiting portion (12). The operating handle (2) is pulled reversely, so that the wire comes into contact with the electric conductor (4); when the user pulls and turns up the operating handle (2) again, there is no need to continuously use force, and the wire will be take out easily.
