Electrical Connector Passageways for Stable Cable and PCB Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors, such as the wire-to-board connector described in CN 216120831 U, have increased constructive complexity due to the addition of an interposer, which complicates the connection of cables and terminals.
Innovation Solution
An electrical connector design featuring insulating housings with passageways that include retaining slots and receiving holes, allowing terminals to connect with soldering balls or cables, with hemicycle parts and cable-contacting faces to position conductive ends securely when connected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an interposer is added to connect cables and terminals, then the connection capability is improved, but the constructive complexity increases
Solution Approach 1:
The patent removes the interposer component from the connector structure. The insulating housing now directly provides passageways that allow terminals to connect with cables or soldering balls without requiring an additional interposer layer, thereby reducing constructive complexity while maintaining connection capability
Solution Approach 2:
The insulating housing is designed to perform multiple functions: it provides structural support, guides terminal insertion through passageways, and enables both cable connections and PCB mounting through the same basic structure. The passageways themselves serve universal purposes for different connection types without requiring separate components
2Device complexity
If the connector structure is simplified by removing the interposer, then the constructive complexity is reduced, but the stability of terminal attachment may be compromised
Solution Approach 1:
The passageways in the insulating housing are designed with specific local features including retaining slots and receiving holes that provide targeted stabilization. The hemicycle parts within the receiving holes specifically position cable-contacting faces to ensure stable cable attachments, while other portions of the passageways facilitate terminal insertion and PCB mounting
Solution Approach 2:
The insulating housing acts as an intermediary structure that directly provides the stabilization function previously performed by the interposer. The hemicycle parts and cable-contacting faces within the housing's passageways serve as the mediating elements that ensure stable cable attachments without requiring a separate interposer component

AI summary
An electrical connector includes: an insulating housing defining opposite mating face and mounting face and having plural passageways arranged in an array and running through the mating face and the mounting face, each passageway having a retaining slot and a receiving hole communicating with each other; plural terminals each comprising a retaining portion retained in the retaining slot, a mating portion, and a cable-contacting face which orients the receiving hole, wherein viewed in a mating direction of the electrical connector each of the receiving hole has a hemicycle part, the terminals are adapted to connect with soldering balls or cables, and conductive ends of the cables are inserted in the receiving holes and positioned between the hemicycle parts and corresponding contacting faces when the terminals are connected with the cables.
