Solution Overview

Problem

Existing electrical connection devices require specialized assembly jigs for the elastic element, making the assembly process inconvenient and time-consuming.

Innovation Solution

An electrical connection device with a first connector and a second connector, featuring a first plastic core, terminals, an inner casing member, an elastic element, and an outer casing member, allowing for assembly without specialized jigs, with the elastic element placed in an accommodating groove and engaging bodies on the outer casing member for automatic reset functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an elastic element is disposed in the first connector or the second connector to provide kinetic energy for resetting, then the automatic reset function is achieved, but special jigs are required for the assembly of the housing of the connectors, causing inconvenience in the assembly

Engineering Contradiction:
Improveautomatic reset functionVSAvoidassembly convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The elastic element is nested within the accommodating groove that is formed in the housing structure itself. The accommodating groove is disposed in the first housing or second housing, allowing the elastic element to be integrated into the housing rather than requiring separate assembly fixtures. This nesting approach enables the elastic element to be properly positioned and secured during normal assembly operations without requiring special jigs.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The housing structure itself provides the accommodating groove that serves the dual purpose of both housing the elastic element and guiding its proper placement during assembly. The groove's geometry is designed to automatically guide the elastic element into the correct position and orientation, allowing the structure to serve its own assembly needs without external assistance from specialized fixtures.

Inventive Principle:
Principle #25Self-service

2Reliability

If a locking structure is provided between the first connector and the second connector to provide secure bonding, then the connection reliability is improved, but the device complexity increases

Engineering Contradiction:
Improveconnection securityVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking structure is merged with the housing components of the connectors. The first housing and second housing incorporate locking features directly into their structures, allowing the locking function to be integrated with the housing rather than being a separate additional mechanism. This merging reduces the number of discrete parts and simplifies the overall device complexity while maintaining secure bonding between connectors.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The housing structure serves multiple functions simultaneously: it provides mechanical protection for the terminals, guides the insertion and alignment of connectors, and incorporates the locking mechanism. By making the housing multi-functional, the patent avoids adding separate dedicated components for each function, thereby reducing overall device complexity while ensuring reliable connection security.

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

AI summary

An electrical connection device having an automatic reset function for plugging and unplugging includes a first connector and a second connector. The first connector includes a first plastic core, first terminals, an inner casing member, an elastic element, and an outer casing member. The first terminals are disposed on the first plastic core, and each of the first terminals has a first contact end and a first connection end. The inner casing member is disposed outside the first plastic core, an outer side of the inner casing member has an accommodating seat disposed thereon, and the accommodating seat has an accommodating groove. The elastic element is able to be placed in the accommodating groove along the axial direction of the inner casing member through the opening. The second connector includes a second plastic core, second terminals, and an outer housing.
