6824415, Nov 30, 2004

Filed:

Nov 1, 2001

Appl. No.:

10/004460

Inventors:

James J. Wlos - Crete IL

Assignee:

Andrew Corporation - Orland Park IL

International Classification:

H01R 424

US Classification:

439348

Abstract:

A locking mechanism for a coaxial connector assembly of the type wherein an inner cylindrical connector member of a female connector is adapted for receipt within an outer connector member of a male connector. The locking mechanism is positionable between the male and female connectors and includes one or more locking balls disposed within a sleeve portion of the male connector. The sleeve is of the push-pull variety and incorporates an internal surface for biasing the locking ball or balls into a recess formed in the female connector. When the sleeve is in a locked position, the locking ball or balls captured therein are biased radially inwardly therefrom to urge the male and female connectors into a tighter engagement.

Assignee:

Andrew Corporation - Orland Park IL

International Classification:

H01R 1704

US Classification:

439585, 439578

Abstract:

A corrugated coaxial cable connector, field installable with a hand crimp tool has a connector interface coupled to the connector end of a hollow cylindrical body; an inner surface of the body is adapted to thread onto the helical corrugations on the outer conductor of the cable. A plurality of ridges on an outer surface of the body corresponding to an internal threaded section forms a crimp surface. An inner contact located coaxially within the body has a socket contact section at the cable end dimensioned for insertion of the inner conductor of the cable and electrical connection therewith. A body barb located on the outer surface of the body provides an acute surface for heat shrink tubing to seal against.

Assignee:

Andrew Corporation - Orlando Park IL

International Classification:

H01R 1704

US Classification:

439585, 434578

Abstract:

A cable-connector system advantageously used with flexible, relatively small diameter coaxial cable and connectors, including a coaxial cable with a foam dielectric surrounding an inner conductor; and a tubular outer conductor surrounding the foam dielectric, the outer conductor being composed of aluminum or aluminum alloy and having helical corrugations; and a connector, having: a connector body having a hollow bore with internal perturbations keyed to the helical corrugations and arranged to retentively receive and secure the connector on the cable when the connector is screwed onto the cable with the corrugations engaging the perturbations; the connector body having a crimp section adapted to be compressed by a connector crimping tool; the crimp section configured such that when crimped, the crimp section deforms inwardly and distorts the cable outer conductor corrugations to prevent relative rotation between the cable and the connector body and interlock the connector and cable.

Appl. No.:

10/708859

Inventors:

John Dykstra - Tinely Park IL, US
James Wlos - Crete IL, US
Larry Buenz - Tinley Park IL, US

Assignee:

Andrew Corporation - Orland Park IL

International Classification:

H01R009/05

US Classification:

439578, 439583

Abstract:

A coaxial connector may be configured with multiple interleaved concentric threads that reduce connector assembly threading requirements. A cable sheath stripping feature may be incorporated into the connector, eliminating the need for a separate sheath stripping tool. Also, over-tightening protection assemblies may be incorporated in the coupling and or rear clamp nuts. The over-tightening protection assemblies utilize first and second interlock surfaces which co-operate to couple the connector body with a rotatable inner coupling sleeve until a predetermined level of torque is applied whereupon complementary protrusions formed on the rings deflect and slip past each other, protecting the connector and or cable from damage due to application of excessive torque and eliminating the need for torque wrenches during connector installation. The first and second interlock surfaces may be formed directly in the coupling nut and inner coupling sleeve or may be separate finger and ramp rings coupled to each.

International Classification:

H01R 9/05

US Classification:

439583

Abstract:

An electrical connector having a longitudinal axis with interface and cable ends for coaxial cable having an annular corrugated solid outer conductor. The connector having a body and an interface joined in an interference fit along the longitudinal axis of the connector. A spring finger ring within a bore of the body is rigidly connected to the body. The spring finger ring having a plurality of spring fingers extending towards an connector end; the spring fingers having an inward projecting bead at the connector end. The spring fingers positioned opposite an outer conductor groove open to the cable end, the outer conductor groove proximate the cable end of the interface.

Assignee:

Andrew Corporation - West Chester IL

International Classification:

H01R 9/05

US Classification:

439578

Abstract:

A push-on connector interface and associated spring ring adapted for use with, for example, existing standardized threaded female connectors, for example SMA or Type N connectors. A plurality of spring fingers of the male connector body engage the, typically threaded, outer diameter surface of the female connector body. A sleeve within the male connector body may be adapted to extend within a bore of the female connector body. A spring or spring ring located, for example, positioned within a groove or press-fit upon the sleeve has a plurality of deflectable protrusions which deform between the sleeve and an inner diameter surface of the bore and or are biased against the inner diameter surface. The connections formed by the bias of spring fingers and the deformation and or bias of the spring or spring ring creating a reliable mechanical and electrical interconnection between the male and female connector bodies.
