Electrical Connector Shielding Housing Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional HDMI electrical connectors face installation inconvenience due to multiple components and weak assembly strength, leading to time-consuming assembly processes and potential damage from wire oscillation, which limits miniaturization and reliability.
Innovation Solution
The design integrates the upper and lower shell bodies of the shielding housing through riveted buckle holes and buckling sheets, creating a single, robust unit that securely clamps the wire and reduces oscillation, enhancing the connector's bulk intensity and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the rear shell is designed as multiple individual parts (front shell and rear shell), then the assembly can be manufactured separately, but the assembly process becomes time-consuming and requires manual pressing and reassembling
Solution Approach 1:
The patent merges the front shell and rear shell into a single integrated rear shell structure. The rear shell includes a body portion that forms the wired position and a clamping portion that extends forward to engage with the front shell, eliminating the need for separate assembly of multiple shell parts and reducing assembly time.
Solution Approach 2:
The integrated rear shell is segmented into functional portions: a body portion for housing the wired position and a clamping portion for securing the front shell. This segmentation within a unified structure allows each portion to perform its specific function while maintaining overall structural integrity and simplifying the assembly process.
2Ease of manufacture
If the rear shell uses a convex hull and concave slot engagement structure, then the upper and lower shell bodies can be mutually engaged, but the clamping force is limited and internal components loosen when wire oscillation is large
Solution Approach 1:
The wire is pre-clamped by the clamping portion of the rear shell before final assembly. The clamping portion extends forward to engage with the front shell, pre-positioning and securing the wire in place to prevent oscillation and loosening during operation.
Solution Approach 2:
The clamping portion features a curved engagement surface that complements the front shell geometry, creating a more robust engagement than flat convex-concave interfaces. This curved design distributes stress more evenly and prevents component loosening under wire oscillation.
3Adaptability or versatility
If the connector uses standardized size specifications, then compatibility is ensured, but miniaturization cannot be achieved for market diversification
Solution Approach 1:
The patent applies local quality optimization by reducing the size of specific components (tongue piece, base seat, wire clip) while maintaining the overall standardized connector dimensions. This allows miniaturization of internal components for market diversification while preserving external compatibility standards.
Solution Approach 2:
The patent optimizes component arrangement in three-dimensional space, repositioning elements vertically and horizontally to reduce the overall envelope dimensions. The wire clip and terminal set are arranged to maximize space utilization, enabling miniaturization without compromising functionality or standardization.

AI summary
An electrical connector includes an insulating body, a terminal set, a wire, and a shielding housing having an upper shell body and a lower shell body. A support part of the first buckling sheet which is penetrated through a first buckle hole of the lower shell body is rivetedly pressed on an outer peripheral edge of the first buckle hole of the lower shell body. An upper side and a lower side of the wire are pressed by a top plate of the upper shell body and the bottom plate of the lower shell body so that the upper and lower shell bodies of the shielding housing can be integrally formed, thereby promoting the bulk intensity of the produced electrical connector, preventing the internal mechanism of the electrical connector from damage due to the oscillation of the wire, and promoting the reliability of the produced electrical connector.
