Connector Ground Plate Insert Molding Crosstalk Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The reduction of the thickness of the plate-like portion in connectors compromises the electrical characteristics, such as crosstalk, and mechanical strength, making it difficult to achieve miniaturization and thinning while maintaining performance.
Innovation Solution
A connector design featuring a housing with a plate-like portion and a ground plate embedded by insert molding, where the ground plate has openings that connect with the housing's surfaces, reducing crosstalk and enhancing mechanical strength by positioning the ground plate between contact portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the thickness of the plate-like portion is reduced to achieve miniaturization and thinning, then the size of the connector is reduced, but the electrical characteristics such as crosstalk and mechanical strength deteriorate
Solution Approach 1:
The ground plate is segmented into a main portion and multiple protruding portions that extend into the openings of the housing. This segmentation allows the ground plate to maintain effective grounding function while adapting to the reduced thickness of the plate-like portion, thereby preventing crosstalk without requiring increased overall thickness.
Solution Approach 2:
The ground plate extends in the thickness direction of the plate-like portion through its protruding portions that fit into openings of the housing. This dimensional extension compensates for the reduced thickness of the plate-like portion, maintaining the grounding effectiveness and mechanical support needed to prevent crosstalk.
2Volume of moving object
If the thickness of the plate-like portion is reduced to achieve miniaturization and thinning, then the size of the connector is reduced, but the mechanical strength deteriorates
Solution Approach 1:
The ground plate is divided into a main portion and multiple protruding portions that extend into the openings of the housing. This segmentation provides distributed mechanical support at multiple locations along the plate-like portion, enhancing overall mechanical strength without increasing the thickness of the plate-like portion itself.
Solution Approach 2:
The connector employs a composite structure combining the housing, the plate-like portion, and the ground plate with protruding portions. This composite design creates a reinforced structure where the ground plate acts as both an electrical ground and a mechanical reinforcement element, compensating for the reduced thickness of the plate-like portion.

AI summary
A connector is mateable with a mating connector along a mating direction. The connector comprises a housing, a plurality of first contacts, a plurality of second contacts and a ground plate. The housing has a plate-like portion extending in a predetermined plane which is defined by the mating direction and a pitch direction perpendicular to the mating direction. The plate-like portion has a first principal surface and a second principal surface which is opposite to the first principal surface in a predetermined direction perpendicular to both the mating direction and the pitch direction. The first contacts are held by the housing. The first contacts have first contact portions, respectively. The second contacts are held by the housing. The second contacts have second contact portions, respectively. The ground plate includes a main portion. The main portion is formed with a plurality of openings. Each of the openings pierces the main portion in the predetermined direction and has a closed periphery in the predetermined plane. The main portion is embedded in the plate-like portion by insert molding. The main portion is positioned between the first contact portions and the second contact portions in the predetermine direction.
