Solution Overview

Problem

Conventional connectors require bending of contact terminals to connect with a PCB, leading to increased space occupation and limited miniaturization potential due to the need for multiple terminals to transmit a large number of signals.

Innovation Solution

A connector design featuring an insulating body assembly with terminal assemblies that include a connecting terminal and a contact terminal, where the connecting terminal is in elastic contact with the inner wall of an accommodating hole, allowing for vertical exposure without bending, thus reducing space occupation and enabling more terminals in a limited space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the contact terminal is bent into a semi-circular arc shape to connect with PCB, then the connection between cable and PCB is achieved, but the contact terminal occupies large space and reduces terminal density

Engineering Contradiction:

Improveconnection reliabilityVSAvoidconnector volume

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

Instead of bending the contact terminal outward to achieve connection, the patent inverts the approach by having the connecting terminal insert into the contact terminal from the inside. The connecting terminal's front end is inserted into the accommodating hole of the contact terminal, and the contact protrusion abuts against the inner wall of the accommodating hole, achieving connection without external bending.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent applies nesting by placing the connecting terminal inside the contact terminal structure. The connecting terminal is disposed within the insulating body assembly, and its front end is inserted into the accommodating hole of the contact terminal, creating a nested configuration that saves space while maintaining connection functionality.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Quantity of substance

If more contact terminals are arranged to transmit more signals, then signal transmission capacity increases, but the connector volume increases

Engineering Contradiction:

Improvenumber of contact terminalsVSAvoidconnector volume

Core Design Contradiction:

Quantity of substanceVSVolume of moving object

Solution Approach 1:

The patent changes the spatial arrangement from external bending in one dimension to internal nesting in multiple dimensions. By having the connecting terminal insert into the contact terminal from the inside, the design utilizes the internal space of the contact terminal, effectively adding a dimensional aspect to the arrangement and enabling higher terminal density without increasing overall connector volume.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Reliability

If the contact terminal is bent to achieve connection, then the connection is established, but the PCB may be damaged

Engineering Contradiction:

Improveconnection reliabilityVSAvoidPCB damage risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

Instead of the contact terminal bending outward and potentially damaging the PCB, the patent inverts the mechanism so that the connecting terminal inserts into the contact terminal from the inside. The elastic contact occurs internally within the accommodating hole, eliminating the risk of external damage to the PCB while maintaining reliable connection.

Inventive Principle:

Principle #13The other way round (Inversion)
