Jack Socket Tip Contact Transverse Spacing for Reliable Connection Breaking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional jack sockets experience malfunctions due to insufficient distancing of the contact section of the tip contact from the tip switching contact, particularly when a cable is pulled transversely, leading to unreliable electrical connection breaking between the tip contact and the tip switching contact, especially with varying shapes of contact tips from different manufacturers.
Innovation Solution
The jack socket design features a contact section with a longitudinal extension encompassing the tip contact point and tip switching contact point, spaced apart transversely, ensuring a greater deflection at the tip switching contact point, and a convex or V-shaped design that limits the sinking of the contact section into the constriction, maintaining a defined position for reliable contact opening, even with different contact tip shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the contact section of the tip contact is allowed to deflect freely when a jack plug is inserted, then the electrical connection can be established, but the distancing from the tip switching contact becomes insufficient leading to unreliable connection breaking
Solution Approach 1:
The contact section is pre-configured with a longitudinal extension that positions the tip contact point and tip switching contact point spaced apart transversely before insertion occurs. This preliminary geometric arrangement ensures that when deflection happens during insertion, the contact section will naturally achieve sufficient distancing from the tip switching contact, preventing unreliable connection breaking while maintaining smooth operation
Solution Approach 2:
The contact section is designed with a longitudinal extension that creates spatial separation in the transverse dimension between the tip contact point and tip switching contact point. By utilizing this additional dimensional spacing rather than relying solely on axial positioning, the design ensures reliable connection breaking occurs even when the contact section deflects during plug insertion
2Reliability
If the contact section sinks into the constriction of the contact tip, then contact is established, but the position becomes undefined leading to unreliable contact opening
Solution Approach 1:
The contact section incorporates a convex or V-shaped design at the specific location where it interacts with the contact tip constriction. This localized geometric feature creates a defined engagement point that prevents the contact section from sinking too deeply into the constriction, maintaining a controlled and reproducible position that ensures reliable contact opening while still establishing proper electrical connection
3Adaptability or versatility
If the jack socket is designed to accommodate varying contact tip shapes from different manufacturers, then compatibility is improved, but the contact section positioning becomes less reliable
Solution Approach 1:
The contact section is designed with a longitudinal extension that creates transverse spacing between contact points, utilizing a dimensional approach that is less sensitive to variations in contact tip shape. This geometric configuration maintains reliable positioning across different manufacturer specifications while preserving compatibility with varying contact tip geometries

AI summary
A jack socket for making an electrical connection with a jack plug comprises a plug housing (10) with a receiving space into which the plug shaft of the jack plug can be inserted, a sleeve contact (20) for contacting the contact sleeve of the jack plug, a tip contact (30) with a contact section (32) which, when the jack plug is inserted, can be contacted by the contact tip at a tip contact point, and a tip switching contact (40) with a contact section (42) which, without a jack plug inserted, rests on a tip switching contact contact point of the contact section (32) of the tip contact (30) and from which the contact section of the tip contact (30) is lifted when the jack plug is inserted.The connecting sections (21, 31, 41, 51, 61) of the contacts (20, 30, 40, 50, 60) protrude from a connection-side end (14) of the connector housing (10) and have a longitudinal extent parallel to the longitudinal center axis (12) of the receiving space of the connector housing (10). The contact section (32) of the tip contact (30) has a longitudinal extent, at least in an area encompassing the tip contact point and the tip switching contact point, that lies transversely to the longitudinal center axis (12). The tip contact point and the tip switching contact point of the contact section (32) of the tip contact (30) are spaced apart from each other in this direction perpendicular to the longitudinal center axis (12), with the tip contact point being located further away from the free end (34) of the tip contact (30) than the tip switching contact point.
