Abstract
Abstract A connector tool for removing electrical connector housings from a mounting member wherein little or no clearance space exists between adjacent housing members. The housing contains a slotted opening for insertion of a printed circuit board and has a surface adjacent the opening which limits movement of one end of the contacts contained in the housing. The tool comprises locating fingers for correctly positioning the tool in the housing. The locating fingers normally rest upon the mounting member upon insertion of the tool in the housing. A shaft member having a spring member therein is formed integral with the locating fingers. Pawl members which are inserted in the slotted opening in the housing are movable by means of handles pivotably positioned in the shaft member wherein they grasp a portion of the housing surface. Dowel means are used to interconnect the handles, the dowel means being movable in a slot formed in the shaft.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
144 words
A connector tool for removing electrical connector housings from a mounting member wherein said housing contains a slotted opening for insertion of a printed circuit board, said housing having a surface adjacent said opening which limits movement of one end of the connector contacts, said tool comprising: a shaft; locating fingers on one end of said shaft for correctly positioning the tool in the housing; a pair of handles pivotally mounted about an axis extending laterally through said shaft above said fingers; pawl members formed on said handles for insertion in said slotted opening in said housing; said pawl members once inserted in said opening being spread apart to grasp a portion of said surface by pivotal movement of said handles; and movement of said tool in a direction away from said mounting member causing said housing to be removed from said mounting member.
Claim 2
Dependent Claim
144 words
A connector tool for removing electrical connector housings from a mounting member wherein said housing contains a slotted opening for insertion of a printed circuit board, said housing having a surface adjacent said opening which limits movement of one end of the connector contacts, said tool comprising: a shaft; locating fingers on one end of said shaft for correctly positioning the tool in the housing; a pair of handles pivotally mounted about an axis extending laterally through said shaft above said fingers; pawl members formed on said handles for insertion in said slotted opening in said housing; said pawl members once inserted in said opening being spread apart to grasp a portion of said surface by pivotal movement of said handles; and movement of said tool in a direction away from said mounting member causing said housing to be removed from said mounting member.
Claim 3
Dependent Claim
25 words
A connector tool in accordance with claim 1 wherein said locating fingers rest upon the mounting member upon insertion of said tool in the housing.
Claim 4
Dependent Claim
33 words
A connector tool in accordance with claim 1 wherein dowel means are used to pivotally mount said handles on said shaft, said dowel means being movable in a slot formed in said shaft.
Claim 5
Dependent Claim
19 words
A connector tool as set forth in claim 1 including spring means biasing said pawl members toward one another.
Claim 6
Dependent Claim
54 words
A connector tool as set forth in claim 1 wherein said locating fingers are positioned on opposite sides of said pawl members, and said fingers and pawl members are spaced from each other equal distances to allow said fingers and pawl members to be inserted into spaced apart contact compartments in the connector housing.
Claim 7
Dependent Claim
89 words
A connector tool for removing electrical connector housings from a mounting member comprising: a shaft; a pair of handles pivotally mounted about an axis extending laterally through said shaft, each handle having a lower portion extending below said axis and an upper portion extending laterally from said shaft; oppositely extending pawls formed on said lower portions of said handles; and lifting of said handles initially causing said pawls to spread apart for engagement with a surface of the connector housing, and thereafter removing said housing from said mounting member.
Claim 8
Dependent Claim
89 words
A connector tool for removing electrical connector housings from a mounting member comprising: a shaft; a pair of handles pivotally mounted about an axis extending laterally through said shaft, each handle having a lower portion extending below said axis and an upper portion extending laterally from said shaft; oppositely extending pawls formed on said lower portions of said handles; and lifting of said handles initially causing said pawls to spread apart for engagement with a surface of the connector housing, and thereafter removing said housing from said mounting member.
Claim 9
Dependent Claim
25 words
A connector tool as set forth in claim 6 including: a slot extending lengthwise in said shaft, said handles being pivotally mounted in said slot.
Claim 10
Dependent Claim
24 words
A connector as set forth in claim 7 including: a spring in said shaft engaging said handles to bias said pawls toward one another.
Claim 11
Dependent Claim
42 words
A connector as set forth in claim 7 including: a second slot extending lengthwise in said handle in a plane perpendicular to said first-mentioned slot; and a dowel movable lengthwise in said second slot, said handles being pivotally mounted on said dOwel.
Claim 12
Dependent Claim
48 words
A connector as set forth in claim 9 wherein: a bore is formed in said shaft on the side of said handles opposite to said pawls; and a spring is provided in said bore engaging the upper portions of said handles to bias said pawls toward each other.
Claim 13
Dependent Claim
23 words
A connector as set forth in claim 6 including: locating fingers on said shaft for correctly positioning the tool in the connector housing.
