Electrical Connector Frame Segmentation for Chip Module Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors are prone to deformation and damage due to the increasing size of chip modules, leading to poor electrical connections and product defects, as the planar structure of the connectors is not adequately supported to handle the lateral deformation of the chip module.
Innovation Solution
An electrical connector design featuring a housing with a surrounding frame and positioning members on the corners of the frame, which allows the chip module to be securely located on the frame rather than the housing, reducing deformation and enabling separate molding of the housing and frame for improved precision and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the dimension of the chip module increases to accommodate higher operating speeds, then the electrical connection capability is improved, but the deformation of the chip module becomes greater
Solution Approach 1:
The connector is divided into two separate components: the housing and the frame. The frame is molded separately and then assembled to the housing, allowing each part to be optimized independently and reducing overall deformation
2Area of stationary object
If the area of the plate is increased to support larger chip modules, then the electrical connection capability is improved, but the plate becomes prone to deformation and damage
Solution Approach 1:
The planar plate structure is segmented into a housing and a separate frame. The frame provides structural support and is molded separately, preventing the housing from deforming under the weight and lateral forces of large chip modules
Solution Approach 2:
The connector combines the housing (made of insulating material) with a frame (made of reinforcing material) to create a composite structure that maintains electrical insulation while providing enhanced mechanical strength and deformation resistance
3Area of stationary object
If the planar structure of the plate is made larger, then the electrical connection capability is improved, but the manufacturing precision deteriorates due to deformation during formation
Solution Approach 1:
The connector is manufactured in two separate parts (housing and frame) with the frame providing precise positioning features. This segmentation allows each part to be molded with higher precision without the deformation issues that affect large single-piece structures
Solution Approach 2:
The frame is molded separately with pre-formed positioning members that define the exact locations for the housing and terminals. This preliminary formation of the frame ensures precise terminal arrangement before the housing is assembled
