Electrical Connector Yield Slot Wire Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connector assemblies face challenges in miniaturization due to densely arranged wires, which lead to significant space occupation and signal interference, making it difficult to achieve effective shielding.
Innovation Solution
The electrical connector assembly incorporates a middle shielding sheet with a recessed yield slot, allowing the power wire to be soldered between the upper and lower terminal groups, reducing wire density and optimizing space usage while maintaining effective shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each ground terminal and power terminal are soldered separately with individual wires, then reliable electrical connection is achieved, but wire density increases and occupies large space
Solution Approach 1:
The patent combines multiple separate wire soldering operations into a single integrated cable assembly. The cable contains multiple conductors (signal wires, power wire, ground wire) that are bundled together and soldered to corresponding terminals simultaneously, reducing the space required compared to separate wire connections.
Solution Approach 2:
The patent implements a nested structure where the power wire and ground wire are positioned within the cable assembly in a compact arrangement. The power wire is surrounded by the ground wire, creating a shielded configuration that nests multiple functional elements within a confined spatial envelope.
2Adaptability or versatility
If wires are densely arranged to connect all terminals, then complete electrical connectivity is achieved, but signal interference increases and shielding becomes difficult
Solution Approach 1:
The patent introduces a ground wire as an intermediary element that acts as a shield between the power wire and signal wires. This ground wire mediates the electromagnetic environment by providing a reference potential and absorbing or redirecting interference, thereby protecting signal integrity in the dense wire arrangement.
Solution Approach 2:
The patent applies different spatial arrangements to different wire types based on their functional requirements. Signal wires are positioned away from power wires to minimize interference, while ground wires are strategically placed adjacent to power wires and signal wires to provide localized shielding and reference potential where needed.
3Object-affected harmful factors
If the middle shielding sheet is positioned between terminal rows for shielding, then signal interference is reduced, but space for wire routing is limited
Solution Approach 1:
The patent routes wires in three-dimensional space by passing them through slots in the insulating body and positioning them at different depths and angles. The power wire and ground wire are routed through vertical slots and positioned in different horizontal planes, allowing compact wire routing that does not interfere with the lateral positioning of the middle shielding sheet.
Solution Approach 2:
The patent divides the wire routing path into multiple segments through different structural elements. Wires pass through slots in the insulating body, navigate around the middle shielding sheet, and connect to terminals through designated openings. This segmented routing allows the wire bundle to weave through the connector structure without requiring large continuous spaces.

AI summary
An electrical connector includes an insulating body, a middle shielding sheet, an upper power terminal, a lower power terminal, and a cable. The middle shielding sheet is arranged in the insulating body, and has a base and an extending portion extending backward from the base. The extending portion is recessed with at least one yield slot. The upper power terminal extends to form an upper soldering portion entering a part above the yield slot. The lower power terminal extends to form a lower soldering portion entering a part below the yield slot. The cable has at least one power wire. The power wire has a wire core. The wire core enters the yield slot, extends to a part between the upper soldering portion and the lower soldering portion, and is soldered with the upper soldering portion and the lower soldering portion.
