Abstract
Abstract A terminal crimping tool including a pair of elongate members movable toward and away from each other and having longitudinal facing regions provided with a recessed configuration so as to be spaced apart when moved toward each other, and a pair of facing regions at one end of the longitudinal regions having a complementary receiver and indentor for crimping a terminal barrel with its connector between the first mentioned pair of facing regions.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
178 words
A tool for crimping a terminal having a connector and a transverse barrel at one end of the connector, said tool comprising a pair of pivotally connected levers movable toward and away from each other, a first pair of facing regions longitudinally on said levers and provided with an overall recessed configuration so as to be spaced apart to receive the connector when said levers are moved toward each other, a second pair of facing regions on said levers at one end of said first pair of facing regions, initial complementary receiver and indentor means on said second pair of facing regions for crimping a terminal barrel of one size range with its connector protectively received between said first pair of facing regions, a third pair of facing regions on said levers at the other end of said first pair of facing regions, and additional complementary receiver and indentor means on said third pair of facing regions for crimping a terminal barrel of another size range with its connector protectively received between said first pair of facing regions.
Claim 2
Dependent Claim
178 words
A tool for crimping a terminal having a connector and a transverse barrel at one end of the connector, said tool comprising a pair of pivotally connected levers movable toward and away from each other, a first pair of facing regions longitudinally on said levers and provided with an overall recessed configuration so as to be spaced apart to receive the connector when said levers are moved toward each other, a second pair of facing regions on said levers at one end of said first pair of facing regions, initial complementary receiver and indentor means on said second pair of facing regions for crimping a terminal barrel of one size range with its connector protectively received between said first pair of facing regions, a third pair of facing regions on said levers at the other end of said first pair of facing regions, and additional complementary receiver and indentor means on said third pair of facing regions for crimping a terminal barrel of another size range with its connector protectively received between said first pair of facing regions.
Claim 3
Dependent Claim
22 words
A tool according to claim 1, said first pair of facing regions having concave surfaces for crimping engagement with longitudinal terminal barrels.
Claim 4
Dependent Claim
18 words
A tool according to claim 1, said recessed configuration being located in at least one of said levers.
Claim 5
Dependent Claim
40 words
A tool according to claim 1, said initial and additional receiver and indentor means each being defined by an arcuate cutout in the respective lever, and a protuberance on the respective lever in facing spaced relation with the associated cutout.
Claim 6
Dependent Claim
22 words
A tool according to claim 4, said cutouts being located in one lever, and said protuberances being located in the other lever.
Claim 7
Dependent Claim
18 words
A tool according to claim 5, said recessed configuration being located in said other lever between said protuberances.
Claim 8
Dependent Claim
16 words
A tool according to claim 4, said cutouts being arcuate and opening transversely through respective levers.
Claim 9
Dependent Claim
25 words
A tool according to claim 7, said first pair of facing regions having concave surfaces of reduced area for crimping engagement with longitudinal barrel terminals.
Claim 10
Dependent Claim
243 words
A tool for crimping a terminal having a connector and a transverse barrel at one end of the connector, said tool comprising a pair of pivotally connected levers movable toward and away from each other, a first pair of facing regions longitudinally on said levers and provided with a recessed configuration so as to be spaced apart when said levers are moved toward each other, a second pair of facing regions on said levers at one end of said first pair of facing regions, initial complementary receiver and indentor means on said second pair of facing regions for crimping a terminal barrel of one size range with its connector protectively received between said first pair of facing regions, a third pair of facing regions on said levers at the other end of said first pair of facing regions, and additional complementary receiver and indentor means on said third pair of facing regions for crimping a terminal barrel of another size range with its connector protectively received between said first pair of facing regions, said first pair of facing regions having concave surfaces for crimping engagement with longitudinal terminal barrels, said first pair of facing regions diverging from each other in the direction toward the pivotal connection of said levers when the latter are moved to their limiting position toward each other, for equalized crimping of a longitudinal terminal barrel across its width without the barrel tending to shift away from the pivotal connection.
Claim 11
Dependent Claim
243 words
A tool for crimping a terminal having a connector and a transverse barrel at one end of the connector, said tool comprising a pair of pivotally connected levers movable toward and away from each other, a first pair of facing regions longitudinally on said levers and provided with a recessed configuration so as to be spaced apart when said levers are moved toward each other, a second pair of facing regions on said levers at one end of said first pair of facing regions, initial complementary receiver and indentor means on said second pair of facing regions for crimping a terminal barrel of one size range with its connector protectively received between said first pair of facing regions, a third pair of facing regions on said levers at the other end of said first pair of facing regions, and additional complementary receiver and indentor means on said third pair of facing regions for crimping a terminal barrel of another size range with its connector protectively received between said first pair of facing regions, said first pair of facing regions having concave surfaces for crimping engagement with longitudinal terminal barrels, said first pair of facing regions diverging from each other in the direction toward the pivotal connection of said levers when the latter are moved to their limiting position toward each other, for equalized crimping of a longitudinal terminal barrel across its width without the barrel tending to shift away from the pivotal connection.
Claim 12
Dependent Claim
74 words
A tool according to claim 9, said second pair of facing regions being located proximate to the pivotal connection of said levers and said third pair of proximate regions being located remote from the pivotal connection of said levers, said second pair of facing regions being larger than said third pair of facing regions to accomodate larger terminal barrels in said second pair of facing regions and apply greater force by the greater leverage.
