Electric Connector Crosstalk Reduction via Nested Grounding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors require a complex structure with exposed metal plates and extraction holes to connect to a ground conductor, leading to a complicated design.
Innovation Solution
An electrical connector design where a conductive member is inserted into a receiving hole in the housing to contact a ground contact, eliminating the need for a two-piece structure and extraction holes, while reducing crosstalk between contact groups through strategically positioned ground contacts and crosstalk reducers.

Engineering Contradiction Analysis
1Object-affected harmful factors
If a metal plate is used to reduce crosstalk between contact groups, then crosstalk is reduced, but the housing structure becomes complicated requiring extraction holes or two-piece construction
Solution Approach 1:
The conductive member is inserted into a receiving hole within the housing, nesting the grounding function inside the existing housing structure without requiring external modifications or additional pieces. This eliminates the need for extraction holes while maintaining crosstalk reduction.
Solution Approach 2:
The conductive member is extracted as a separate insertable component rather than being integrated into the housing structure. This allows the grounding function to be achieved through simple insertion into a receiving hole, avoiding complicated housing construction while still reducing crosstalk effectively.
2Reliability
If extraction holes are provided in the housing to connect the metal plate to ground, then ground connection is achieved, but the housing structure becomes complicated
Solution Approach 1:
The receiving hole is formed within the existing housing structure, nesting the ground connection pathway inside the housing rather than requiring external extraction holes. This maintains reliable ground connection while avoiding structural complications.
Solution Approach 2:
The conductive member acts as an intermediary component that bridges the ground contact and the housing interior. It is inserted through a receiving hole to establish ground connection, eliminating the need for complex extraction hole structures while ensuring reliable grounding.
3Ease of operation
If a two-piece housing structure is used to accommodate the metal plate, then the conductive member can be positioned, but the manufacturing process becomes more complex
Solution Approach 1:
The conductive member is nested within a single-piece housing through a receiving hole, achieving proper positioning without requiring two-piece construction. This maintains ease of operation for conductive member placement while simplifying manufacturing by using a monolithic housing structure.

AI summary
[Object] The invention provides an electrical connector having a cross crosstalk prevention member such as a metal plate readily connectable to ground with simple structure of the connector itself. [Configuration] The electrical connector includes: a housing 10 with an receiving hole 120; contact groups 200a and 200b, being arranged on opposite sides of the receiving hole 120 in the housing 10; and a multilayer circuit board 300 to be received in the receiving hole 120 and interposed between the contact groups 200a, 200b. The contact groups 200a, 200b includes ground contacts 220a, 220b. The multilayer circuit board 300 includes a solid conductor layer 310 provided inside the multilayer circuit board 300, ground conductors 322, 332 provided on a surface of the multilayer circuit board 300, and through-holes 340 to connect the solid conductor layer 310 with the conductors 322, 332. When the multilayer circuit board 300 is received in the receiving hole 120, the conductors 322, 332 are in contact with the contacts 220a, 220b.
