High Voltage Shield Connector Locking Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high voltage shield connectors are prone to connection failure due to frequent disconnection and reconnection, which can lead to malfunctioning electronic devices in vehicles, as they lack effective mechanisms to prevent accidental disconnection.
Innovation Solution
A locking device with a restraining member and damping member is integrated into the high voltage shield connector, featuring a locker on the male housing and a damping member with a coil spring shape between the fixing member and female housing to maintain connection stability and absorb external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hook-like connection method is used to connect male and female housings, then the connector can be easily assembled and disassembled, but the connection becomes loose due to frequent disconnection and reconnection
Solution Approach 1:
The locking device is divided into separate functional components: a locking protrusion on the male housing, a corresponding locking groove on the female housing, and a resilient locking member that engages these features. This segmentation allows the connection to be easily assembled while the locking mechanism maintains stability during frequent disconnection and reconnection cycles
Solution Approach 2:
The locking member is designed with resilient properties, allowing it to dynamically adapt during assembly and disassembly operations. The resilient nature enables the locking mechanism to maintain engagement force while accommodating the dynamic stresses of frequent connection changes, preventing the connection from becoming loose
2Device complexity
If no damping mechanism is provided, then the connector structure remains simple, but external axial forces can cause damage or disconnection
Solution Approach 1:
A damping member in the form of a coil spring is pre-installed between the fixing member and the female housing to provide cushioning against external axial forces before they can cause damage. This beforehand cushioning protects the connector while maintaining relatively simple overall structure
Solution Approach 2:
The coil spring acts as an intermediary element between the fixing member and the female housing, absorbing and attenuating external axial forces. This intermediary damping mechanism protects the connection without requiring complex structural modifications to the main connector body
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents accidental disconnection and enhances connection reliability by maintaining the connection between male and female housings even during frequent assembly and disassembly, while also improving damping force against external axial forces.
Implementation Method 1
a damping member having a coil spring shape is preferably provided between a fixing member fixing a female housing and the female housing so as to suitably improve damping force when an external force in the axial direction is suitably generated
