Stapler Fixation Structure for Electrical Wire Board Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical-wire fixation structures require complex configurations, such as cutout grooves on the wiring plate, to effectively secure electrical wires, which can be improved for easier and more reliable fixation.
Innovation Solution
A fixation structure comprising a conductive core wire covered by a cover member, with a stapler having a contact part that contacts both the exposed and covered parts of the wire, and fixation parts that penetrate through the cover member to secure the wire to a board, ensuring stable connection and insulation between adjacent core wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a binding band and electrical-wire placement plate unit with cutout grooves are used to fix the electrical wire, then the electrical wire can be bound and fixed, but the wiring plate requires complex cutout grooves to be formed
Solution Approach 1:
The invention extracts the fixation function from the wiring plate by introducing a separate stapler component. The stapler includes a contact part that contacts the electrical wire and fixation parts that penetrate through the wiring plate, separating the fixation mechanism from the plate structure itself and eliminating the need for complex cutout grooves
Solution Approach 2:
The stapler serves as an intermediary component between the electrical wire and the wiring plate. It provides a standardized fixation interface that simplifies both the wiring plate design (no grooves needed) and the wire fixation process, mediating the connection between these two elements
2Manufacturing precision
If the contact part contacts both the core-wire exposed part and core-wire covered part, then assembly accuracy is improved, but the structure becomes more complex
Solution Approach 1:
The contact part is designed with differentiated local properties: an insulative part that contacts the core-wire covered part and a conductive part that contacts the core-wire exposed part. This local quality differentiation enables precise assembly guidance through electrical contact while maintaining electrical insulation where needed, improving assembly accuracy without requiring overly complex structures

AI summary
A fixation structure (1) includes an electrical wire (10), a board (20), and a stapler (30). The electrical wire (10) includes a core wire (10a) that is conductive, and a cover member (10b) that covers the core wire (10a). The electrical wire (10) includes a core-wire covered part (12) covered by the cover member (10b), and a core-wire exposed part (11) exposed from the core-wire covered part (12). The board (20) includes a junction part (22) electrically connected with the core-wire exposed part (11). The stapler (30) includes a contact part (31a) and a fixation part. The contact part (31a) has a plate shape, and is positioned at a boundary (13) between the core-wire exposed part (11) and the core-wire covered part (12) while contacting the core-wire exposed part (11) and the core-wire covered part (12) from a side opposite to the board (20) when the core-wire exposed part (11) is connected with the junction part (22). A pair of the fixation parts are provided on both sides of the contact part (31a) and fix the contact part (31a) and the board (20).
