LVDS Connector Insert Molding for Terminal Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LVDS connectors face issues with conductive terminals experiencing looseness or warping due to insufficient strength and complex assembly processes, leading to low production efficiency.
Innovation Solution
The LVDS connector design features conductive terminals with elastic contact portions and an insulative housing insert molded with a first plastic body, along with a shielding housing forming a receiving space, which includes a bending portion and second housing, to enhance strength and simplify assembly by using insert molding and specific grooves and pads for secure alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the insulative housing is made thin and elongated to meet production specifications, then the connector meets design requirements, but the overall strength becomes insufficient causing conductive terminals to loosen or deform
Solution Approach 1:
The patent combines the insulative housing and shielding housing into a single integrated component through insert molding. The conductive terminals are embedded directly into the insulative housing, and the shielding housing is molded around it, creating a unified structure that provides both mechanical support and electromagnetic shielding without requiring separate assembly steps.
Solution Approach 2:
The patent uses composite construction by combining different materials (insulative plastic and conductive shielding material) into a single integrated housing structure. This allows the thin insulative housing to gain additional structural strength from the integrated shielding housing while maintaining the required thin profile for production specifications.
2Reliability
If the shielding housing is assembled onto the insulative housing via a buckling structure, then the connector is secured, but the assembly process becomes complicated and time-consuming
Solution Approach 1:
The patent merges the shielding housing and insulative housing into a single integrated component through insert molding, eliminating the need for separate buckling assembly. The conductive terminals are embedded directly into the insulative housing during molding, and the shielding housing is molded around it in one process, removing multiple assembly steps.
Solution Approach 2:
The patent replaces the mechanical buckling assembly process with an insert molding process. Instead of assembling the shielding housing onto the insulative housing using buckling structures, the shielding housing is directly molded around the insulative housing and conductive terminals, substituting mechanical assembly with a molding process.
3Ease of manufacture
If conventional assembly methods are used with separate housing components, then the connector can be assembled, but the production efficiency remains low due to multiple assembly steps
Solution Approach 1:
The patent combines multiple components (insulative housing, conductive terminals, and shielding housing) into a single integrated structure through insert molding. This eliminates the need for separate assembly steps and reduces the number of parts that need to be handled during manufacturing, significantly improving production efficiency.
Solution Approach 2:
The patent performs preliminary embedding of the conductive terminals into the insulative housing during the molding process itself, before final assembly. The shielding housing is then molded around this pre-assembled structure in one continuous process, eliminating the need for subsequent assembly operations.
