Solution Overview

Problem

Conventional plug connector systems fail to meet the requirements of complex applications, such as battery systems, in terms of installation size, operability, and flexibility, particularly in environments with mechanical stress, temperature variations, and high humidity, while also ensuring reliable and secure connections.

Innovation Solution

A plug connector system with a locking element integrated into the socket housing that can be coupled with the pin housing, featuring a transversely movable assurance for locking and secondary contact assurance, allowing for efficient assembly and disassembly without increasing installation size, and incorporating a resilient prefixing element for precise positioning and elasticity to adapt to various conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If additional securing components and locking mechanisms are added to ensure reliable connection, then connection reliability is improved, but installation size and device complexity increase

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

Solution Approach 1:

The patent integrates the locking mechanism directly into the housing structure of the plug connector system. The housing incorporates interlocking elements and locking features as integral parts of its design, eliminating the need for separate locking components. This merging of functions reduces the number of parts while maintaining secure connection reliability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The housing structure serves multiple functions simultaneously: it provides mechanical support, electrical insulation, and integrated locking/securing mechanisms. The design combines these functions into a single multi-functional component, reducing overall device complexity while ensuring reliable connections.

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

2Reliability

If additional securing components and locking mechanisms are added to ensure reliable connection, then connection reliability is improved, but installation size increases

Engineering Contradiction:
Improveconnection reliabilityVSAvoidinstallation size
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The locking and securing functions are merged into the housing structure itself, eliminating the need for additional separate components. This integration allows the connector to maintain reliable connections without increasing installation size, as the housing serves as both the structural support and the locking mechanism.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If robust locking and securing measures are implemented, then connection reliability is improved, but assembly and disassembly effort increase

Engineering Contradiction:
Improveconnection reliabilityVSAvoidassembly effort
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The locking mechanism is designed to engage automatically upon insertion of the plug connector. The housing structures self-lock through integrated interlocking elements that engage when the connectors are mated, eliminating the need for manual locking operations. For disassembly, the design includes simple release mechanisms that allow easy decoupling without complex procedures.

Inventive Principle:
Principle #25Self-service

AI summary

The present invention provides a plug connector system. According to one aspect, a locking element is provided on the socket housing of the system such that a superior degree of flexibility may be achieved upon mounting and connecting the plug connector system, in particular, in critical applications, such as usage in combination with battery modules. In a further aspect, a socket housing and/or a pin housing of the plug connector system are provided with a resilient prefixing element in order to achieve a preliminary fixation corresponding to a degree of elasticity, thereby allowing tolerances to be taken into consideration. In a further aspect, the plug connector system comprises an assurance having a double function, thereby accomplishing the secondary assurance of contacts and the locking of the housing components on the basis of one single component.
