Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire-to-board connectors, especially the vertical type, face issues with easy disconnection and additional wire length requirements, which affect the layout of portable electronics and stability during external forces.
Innovation Solution
A wire-to-board connector assembly design where the wire-end connector is assembled vertically and pulled out horizontally, utilizing a board-end connector with restricting components and elastic elements to secure the wire-end connector in place, preventing escape and eliminating the need for extra wire length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wire-end connector is plugged in horizontally (right-angle type), then the connector is easy to assemble, but additional wire length (10mm-15mm) is required which affects the layout of portable electronic products
Solution Approach 1:
The patent changes the assembly direction from horizontal to vertical by 90 degrees. The wire-end connector is inserted vertically into the board-end connector, eliminating the need for additional wire length while maintaining ease of assembly. This dimensional change resolves the contradiction between ease of operation and wire length requirement.
2Length of moving object
If the wire-end connector is plugged in vertically (vertical type), then the wire length is reduced, but the connector easily escapes during drop test or under external force
Solution Approach 1:
The patent segments the connection stability function into multiple components: the vertical insertion structure, the restricting components with suppressing portions, the blocking bumps, and the elastic elements. Each component contributes to preventing escape in different directions, collectively ensuring connection stability while maintaining vertical insertion benefits.
Solution Approach 2:
The restricting components and blocking structures are designed in advance to prevent escape before it can occur. The suppressing portions and blocking bumps create preliminary resistance against external forces and drop impacts, counteracting potential escape movements before they happen.
3Reliability
If the wire-end connector is plugged in horizontally, then the connector is stable under external force, but additional operating space is required for bending the wire during plugging and pulling
Solution Approach 1:
The patent changes the assembly direction from horizontal to vertical, eliminating the need for lateral operating space for wire bending. The vertical insertion path requires minimal operating space while maintaining connection stability through the integrated restricting and blocking structures.

Function Achieved in This Case
This design ensures easy assembly, stable connection, and resistance to disconnection, maintaining the connector's position without additional wire length, enhancing the structural integrity and usability in compact electronic devices.
Implementation Method 1
The elastic element pushes in a normal manner pushing the restricting components inwardly at a locking location away from the side walls

AI summary
The instant disclosure relates to a wire-to-board connector assembly including a board-end connector and a wire-end connector. The board-end connector has a first insulative housing, a pair of restricting components and a pair of elastic elements. The first insulative housing has a transverse portion and a pair of side walls. The pair of restricting components is movably assembled to the pair of side walls, and has a suppressing portion, respectively. The wire-end connector has a second insulative housing and a plurality of wires. Two sides of the second housing have a wing portion and a blocking bump located above the wing portion, respectively. When the wire-end connector is assembled to the board-end connector, the wing portion is located under the suppressing portion, and the blocking bump is disposed before the front end of the suppressing portion so as to limit the displacement of the wire-end connector.
