Protected Connector Housing With Buffer Sleeve for Dust and Impact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing external electronic components lack protection for their connectors, making them susceptible to damage from improper angling or impact, and they often fail to provide waterproof and dustproof mechanisms, leading to reduced lifespan due to moisture and dust invasion.
Innovation Solution
The solution involves an external electronic component design that includes a body with a first connector, a housing with a notch and surrounding wall, and a buffer sleeve that envelops the surrounding wall. This design protects the connector from damage, provides a waterproof and dustproof seal, and absorbs shock to prevent instantaneous signal interruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connector plug is exposed and protrudes on the outside for easy connection, then the ease of operation is improved, but the reliability deteriorates due to susceptibility to damage from improper angling or impact
Solution Approach 1:
The connector plug is nested within a protective housing structure that includes a buffer sleeve. The buffer sleeve envelops the surrounding wall of the housing, creating a nested configuration where the connector is protected inside layers of structural elements. This allows the connector to remain accessible for connection while being shielded from damage by the housing and buffer sleeve.
Solution Approach 2:
The buffer sleeve acts as an intermediary element between the connector plug and the external environment. It envelops the surrounding wall and provides a cushioning layer that absorbs impact forces before they reach the connector, preventing direct transmission of harmful forces while maintaining operational accessibility.
2Device complexity
If no waterproof or dustproof mechanism is provided to simplify the structure, then the device complexity is reduced, but the reliability deteriorates due to moisture and dust invasion
Solution Approach 1:
The buffer sleeve functions as a flexible protective shell that envelops the surrounding wall of the housing. This flexible shell structure creates a barrier against moisture and dust penetration while maintaining structural integrity. The buffer sleeve's material properties allow it to provide waterproof and dustproof protection without requiring complex sealing mechanisms.
3Reliability
If a protective structure is added around the connector to prevent damage, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The protective housing structure combines multiple functions into a single integrated component. The housing includes both the structural body and the surrounding wall with the buffer sleeve integrated into it. This merging of protective elements into one unified structure provides connector protection without requiring separate, additional components, thereby limiting the increase in device complexity.
4Ease of operation
If the connector is exposed for direct connection, then the ease of operation is improved, but the object-affected harmful factors increase due to impact and improper angling
Solution Approach 1:
The buffer sleeve provides beforehand cushioning by being pre-installed around the surrounding wall of the housing. This cushioning layer is in place before any impact occurs, ready to absorb and dissipate impact forces from improper angling or collisions. The buffer sleeve's material properties enable it to deform elastically during impact, protecting the connector while maintaining connection accessibility.

AI summary
The invention relates to an external assembly component including a body, a housing and a buffer sleeve. The body is provided with a connector. The housing is provided with a notch, and a surrounding wall encircling the notch is erected on an outer side of the housing. The body is accommodated in the housing. The connector passes through the notch toward the outside, the surrounding wall encircles the connector, and the buffer sleeve covers the surrounding wall. Thus, a plug of the connector can be effectively protected from impact and damage, and waterproof and dustproof effects are provided.
