Connector Housing With Improved Latch Members

US Patent:
5382177, Jan 17, 1995
Filed:
Nov 21, 1991
Appl. No.:
7/795583
Inventors:
Richard D. Hutchinson - Greensboro NC
Daines M. Self - Oak Ridge NC
Michael P. Trull - Winston-Salem NC
Assignee:
The Whitaker Corporation - Wilmington DE
International Classification:
H01R 13627
US Classification:
439358
Abstract:
A connector housing includes a pair of latch arms along sides thereof which extend forwardly to latch with corresponding latching means of a housing of a mating connector. Each latch arm is joined integrally to the housing sides by flexible hinge joints which allow the deflection of the latch arm during mating and unmating. The hinge joints include midsections which have enlarged ends extending therefrom. Radiused sections are provided on the enlarged ends, the radiused sections are configured to properly distribute the stresses associated with the latch arms, such that as forces are applied to the latch arms concentration of stresses will be avoided on the hinge joints.

Strain Relief For An Electrical Connector

US Patent:
5653609, Aug 5, 1997
Filed:
Jul 28, 1995
Appl. No.:
8/508648
Inventors:
Richard Edward Orstad - Greensboro NC
Michael Paul Trull - Winston-Salem NC
Jeffrey Allen Dinkel - Greensboro NC
Assignee:
The Whitaker Corporation - Wilmington DE
International Classification:
H01R 1358
US Classification:
439472
Abstract:
The invention comprises a strain relief for an electrical connector wherein the connector has conductor wires extending therefrom. The strain relief comprises a pair of hermaphroditic components. The forward end of the component has a connector engaging section for engaging the connector. The rearward end has a conductor engaging section to secure the conductor wires which extend from the connector. The inner side has two fastening members for securing one of the members to the other. The first of the fastening members is disposed near the rearward end of the component. The second of the fastening members is disposed near the forward end and the connector engaging section. The fastening members are used to secure the components together. The forward end is adjustable independently of the rearward end such that the strain relief is able to fit different size connectors and to accommodate different sizes and numbers of conductor wires.

Electrical Connector Having A Pivot Lock

US Patent:
5643009, Jul 1, 1997
Filed:
Feb 26, 1996
Appl. No.:
8/606709
Inventors:
Jeffrey Allen Dinkel - Greensboro NC
Richard E. Orstad - Greensboro NC
Michael Paul Trull - Winston-Salem NC
Assignee:
The Whitaker Corporation - Wilmington DE
International Classification:
H01R 13424
US Classification:
439595
Abstract:
The invention comprises an electrical connector having a connector housing with contact receiving passages to receive contacts therein and a guide member. A lock housing has a pivot member wherein the pivot member and the guide member cooperate to secure the lock housing to the connector housing and to allow the lock housing to rotate and move longitudinally with respect to the connector housing. The lock housing having a first position with respect to the connector housing wherein the contacts can be loaded into the housing. The lock housing having a second position wherein the contacts are secured within the housing for electrical connection with a matable connector.

Sealed Electrical Connector

US Patent:
5720629, Feb 24, 1998
Filed:
Oct 16, 1996
Appl. No.:
8/733059
Inventors:
Daines Milfred Self - Oak Ridge NC
Michael Paul Trull - Winston-Salem NC
Assignee:
The Whitaker Corporation - Wilmington DE
International Classification:
H01R 1340
US Classification:
439587
Abstract:
An electrical connector comprises a housing defining a plurality of cavities which extend into the housing through a face thereof, and a seal member mountable on the face of the housing. The seal member is a unitary body which includes a flange and a plurality of plugs extending axially from one side of the flange. The plugs are arrayed in correspondence with the plurality of cavities and are dimensioned for sealing engagement in respective ones of the cavities. The seal member has a plurality of openings extending through the flange and through respective ones of the plugs. The openings are dimensioned to permit insertion of respective conductors through the openings and into the cavities when the seal member is mounted on the housing, and withdrawal of the conductors back out through the openings.

Electrical Connector Housing With Improved Contact Insertion

US Patent:
5425661, Jun 20, 1995
Filed:
Sep 29, 1992
Appl. No.:
7/953449
Inventors:
Daines M. Self - Oak Ridge NC
Richard D. Hutchinson - Greensboro NC
Michael P. Trull - Winston-Salem NC
Assignee:
The Whitaker Corporation - Wilmington DE
International Classification:
H01R 13432
US Classification:
439748
Abstract:
An electrical connector (10) having a housing (12) of resilient plastic material of a type molded in a closed mold with bores defined by core pins; the housing including at least a bore (22) extending therealong leading from an insertion segment (36) of a given diameter to receive a contact (12) to a reduced diameter defining a support segment (28) supporting the contact in the housing, and a forward segment (25), with the various segments extending along a common axis (A) and with a beveled transition defined by surfaces (34) extending between the bore of the insertion segment and the bore of the support segment as defined by a series of recesses (30) and segments (32) arranged around the support segment periphery to define a lead-in for the said contact and maintain an approximate constant thickness of material to minimize plastic sinking and distortion.
