AI Technical Summary

Technical Problem

Existing shielded push-pull connectors lack enhanced shielding properties, which can lead to electromagnetic interference and reduced signal integrity.

Method used

The introduction of a shield spring with a tab-shaped protrusion that fits into a corresponding recess on the snap ring, forming a circumferential protrusion that enhances shielding by forming a loop through the shield portion of the push-pull connector to the built-in connector, and is electrically connected to the shield portion of the cable.

Benefits of technology

This configuration significantly improves the shielding effectiveness of the push-pull connector, reducing electromagnetic interference and enhancing signal integrity by ensuring continuous electrical contact under spring action.

Abstract

A shielded push-pull connector (1) having a shield spring (11), the shield spring (11) having tab-shaped protrusions (15, 16) on the front side as viewed in the insertion direction, the snap ring (10) having a tab-shaped recess corresponding to the tab-shaped protrusions (15, 16) of the shield spring (11), the tab-shaped protrusions (15, 16) of the shield spring (11) being disposed in the tab-shaped recess, whereby the tab-shaped protrusions (15, 16) of the shield spring (11) together with the tab-shaped protrusions (15, 16) of the snap ring (10) form a completely circumferential protrusion that abuts against an undercut portion (24) of the built-in connector, and at this time, the shield spring (11) made of a metallic material forms a loop through the shield portion of the push-pull connector (1) to the built-in connector, and the shield spring (11) is electrically connected directly or indirectly to the shield portion of the cable in which the push-pull connector (1) is disposed.
