Assignee:

Leviton Manufacturing Co., Inc. - Little Neck NY

International Classification:

H01R 424

US Classification:

439404, 439595

Abstract:

An electrical connector having a body with a plurality of contact cavities therein, and a plurality of insulation penetrating beam contacts received within the cavities. Each contact has a first end portion to engage a wire located at a first cavity end and a second end portion with a protrusion at a second cavity end. The connector also includes a plurality of resilient spring arms positioned adjacent to the contact cavities. Each arm has a hinge portion attached to the body and a resiliently movable free end portion with a receiving aperture receiving therein the contact protrusion when the contact is in the contact cavity at which the spring arm is positioned. The second cavity end is open and the spring arm is resiliently movable to permit insertion and removal of the contact through the open end.

Assignee:

Leviton Manufacturing Co., Inc. - Little Neck NY

International Classification:

H04M 9/00
H01R 9/24

US Classification:

37941304, 439709

Abstract:

A termination block having spaced apart rear and front faces with rear and front apertures, respectively, and a plurality of mounting surfaces on the rear face. A screw receiving portion receiving a screw is positioned at each mounting surface. An interior recess is between the rear and front faces, accessible from the rear and front faces through the rear and front apertures. A terminal connection pad is positioned at the rear face at each mounting surface, and a plurality of tines extend through the rear aperture and are positioned within the interior recess for access through the front aperture. Each tine has a flat contact end portion. A plurality of trace members positioned at the rear face, each electrically coupling together one of the terminal connection pads and one of the tines. The terminal connection pads, tines and trace members are formed as part of a stamped, thin, flat lead frame.

H01R 13/60
H01R 13/66

US Classification:

4395401

Abstract:

A connector isolation station system includes ports to receive connectors and includes shield members. The shield members have material properties to substantially shield, attenuate, absorb, diminish, or otherwise hinder or at least partially block wireless signals and noise from impinging upon or otherwise interfering with signal transmissions occurring through the connectors located in the connector isolation station. For instance, transmissions through adjacent connectors are substantially prevented from interfering with one another.

Assignee:

Leviton Manufacturing Co., Inc. - Little Neck NY

International Classification:

C25D 17/00

US Classification:

204206

Abstract:

Embodiments of the invention relate to plating systems configured to strip plate a selected portion of a workpiece (e. g. , a lead frame) and methods of plating. In one embodiment, a plating system is configured to plate a selected portion of a workpiece and at least partially compensate for wheel run out. As an alternative, or in addition, to the plating system being configured to at least partially compensate for wheel run out, in another embodiment, a plating system is configured to plate the selected portion of the workpiece and provide for controllably adjusting plating dimensions on the selected portion to be plated.
