Solution Overview

Problem

Conventional electric connectors are prone to misplugging and fail to meet the demands of modern, ultrathin, multi-functional electronic products due to their large dimensions and single functions, and they struggle with high-speed signal transmission stability and reliable grounding, especially in cable and board connectors.

Innovation Solution

A cable connector component with a reduced dimension design featuring a fixed iron shell with a convex hull for easier cable insertion, and a board connector component with enhanced insulating effects and a new grounding path through a shielding plate, ensuring reliable connections and stable high-speed signal transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional electric connectors are used, then they have large dimensions and single function, but they cannot meet the demand of ultrathin multi-functional electronic products

Engineering Contradiction:
Improvemulti-functionalityVSAvoidconnector dimension
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The connector is designed to integrate multiple functions including signal transmission, power supply, and grounding functions within a single component structure, enabling it to meet the multi-functional requirements of modern electronic products while maintaining compact dimensions

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

Multiple functional elements such as terminal pairs for signal transmission, power terminals, and grounding structures are merged into a single integrated connector assembly, reducing the overall volume while providing multiple functions simultaneously

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If high speed connectors with multiple terminal pairs are designed, then transmission capability is improved, but terminal quality requirements increase and high-speed stable signal transmission becomes difficult

Engineering Contradiction:
Improvesignal transmission capabilityVSAvoidterminal quality
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

Different terminal regions are designed with optimized local characteristics - signal terminals are positioned and structured for high-speed transmission with controlled impedance, while power terminals are designed for current carrying capacity, and grounding terminals are configured for electromagnetic shielding, thereby achieving high-speed stable signal transmission without excessive manufacturing precision requirements across all terminals

Inventive Principle:
Principle #3Local quality

3Ease of manufacture

If cable connector and board connector are connected through SMT grounding, then assembly is simplified, but grounding reliability is insufficient and connection reliability is adversely affected

Engineering Contradiction:
Improveassembly simplicityVSAvoidgrounding reliability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The grounding function is built into the connector structure itself through integrated grounding terminals and shielding plates that are pre-assembled and electrically connected during connector manufacturing, rather than relying on post-assembly SMT grounding processes. This preliminary integration of grounding ensures reliable electrical connection and electromagnetic shielding while maintaining assembly simplicity

Inventive Principle:
Principle #10Preliminary action

4Volume of moving object

If cable connector dimension is reduced, then it meets ultrathin product requirements, but it becomes difficult to connect core wires and terminals while maintaining appropriate external dimension

Engineering Contradiction:
Improveconnector dimensionVSAvoidcore wire connection
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The connector employs a layered three-dimensional structure where core wires are routed through vertical channels and connected to terminals on different levels via the printed circuit board. This dimensional arrangement allows efficient space utilization with compact external dimensions while maintaining adequate internal space for core wire connection operations

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

The invention provides a cable connector component, a board connector component, and an electric connector assembly thereof. The cable connector component includes a connector, a fixed iron shell, and a cable including a plurality of core wires. The connector includes at least one pair of terminal pair, a first insulating body, a first metal shell, a group strip, and a printed circuit board. The terminal pair, the ground strip, and the first metal shell are assembled with the first insulating body. The first metal shell is assembled with the fixed iron shell. The fixed iron shell includes a convex hull which facilitates the cable to insert into the fixed iron shell. The board connector component, includes: a second metal shell including a butting chamber, a terminal group and a second insulting body which are fixed in the second metal shell. The second insulting body includes a base and a clapper disposed at a front end of the base. The clapper includes a first surface and a second surface which are disposed oppositely. A shielding plate is disposed between the first surface and the second surface, and the shielding plate includes a protrusion which is extended out of a side of the base and abuts against the second metal shell. As a result, a new grounding path is formed, which can reduce the electromagnetic interference and strengthen the insulating effect.
