Abstract
Abstract A contact terminal is disclosed which comprises a terminal portion of a high voltage resistor wire and an engagement portion formed integrally with a gripper portion for engaging an electrode of a spark plug or the like. A pressure contact tab is integrally formed in an intermediate portion between the gripper portion and the engagement portion. The pressure contact tab may be bent at a right angle relative to an axis of the terminal.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
131 words
A contact terminal comprising: a gripper portion for contacting and fastening a terminal portion of a high voltage resistor wire; an engagement portion formed integrally with said gripper portion for engaging an electrode of an electrical device such as a spark plug; an intermediate portion of said terminal between said gripper portion and said engagement portion; a pressure contact tab integrally formed with said intermediate portion at a rear edge of said gripper portion, said pressure contact tab being bent at a right angle relative to the longitudinal axis of the contact terminal; and a projection for supporting said pressure contact tab and for preventing movement of said tab towards said engagement portion, said prjection being formed by cutting and raising the projection from a bottom wall of said intermediate portion.
Claim 2
Dependent Claim
131 words
A contact terminal comprising: a gripper portion for contacting and fastening a terminal portion of a high voltage resistor wire; an engagement portion formed integrally with said gripper portion for engaging an electrode of an electrical device such as a spark plug; an intermediate portion of said terminal between said gripper portion and said engagement portion; a pressure contact tab integrally formed with said intermediate portion at a rear edge of said gripper portion, said pressure contact tab being bent at a right angle relative to the longitudinal axis of the contact terminal; and a projection for supporting said pressure contact tab and for preventing movement of said tab towards said engagement portion, said prjection being formed by cutting and raising the projection from a bottom wall of said intermediate portion.
Claim 3
Dependent Claim
130 words
A contact terminal comprising: a gripper portion for contacting and fastening a terminal portion of a high voltage resistor wire; an engagement portion formed integrally with said gripper portion for engaging an electrode of an electrical device such as a spark plug; an intermediate portion of said terminal between said gripper portion and said engagement portion; a pressure contact tab integrally formed with said intermediate portion at a rear edge of said gripper portion, said pressure contact tab being bent at a right angle relative to an axis of the contact terminal; and at least one claw for supporting the pressure contact tab and for preventing movement of said tab towards said engagement portion, said claw being formed from a projection extending from a rear edge of the gripper portion.
Claim 4
Dependent Claim
130 words
A contact terminal comprising: a gripper portion for contacting and fastening a terminal portion of a high voltage resistor wire; an engagement portion formed integrally with said gripper portion for engaging an electrode of an electrical device such as a spark plug; an intermediate portion of said terminal between said gripper portion and said engagement portion; a pressure contact tab integrally formed with said intermediate portion at a rear edge of said gripper portion, said pressure contact tab being bent at a right angle relative to an axis of the contact terminal; and at least one claw for supporting the pressure contact tab and for preventing movement of said tab towards said engagement portion, said claw being formed from a projection extending from a rear edge of the gripper portion.
Claim 5
Dependent Claim
111 words
A contact terminal comprising: a gripper portion for contacting and fastening a terminal portion of a high voltage resistor wire; an engagement portion formed integrally with said gripper portion for engaging an electrode of an electrical device such as a spark plug; an intermediate portion of said terminal between said gripper portion and said engagement portion; a pressure contact tab integrally formed with said intermediate portion, said pressure contact tab being bendable at a right angle relative to an axis of the contact terminal; and a reinforcement tab integrally formed with said pressure contact tab, said reinforcement tab being bent so as to overlap a substantial portion of said intermediate portion.
Claim 6
Dependent Claim
111 words
A contact terminal comprising: a gripper portion for contacting and fastening a terminal portion of a high voltage resistor wire; an engagement portion formed integrally with said gripper portion for engaging an electrode of an electrical device such as a spark plug; an intermediate portion of said terminal between said gripper portion and said engagement portion; a pressure contact tab integrally formed with said intermediate portion, said pressure contact tab being bendable at a right angle relative to an axis of the contact terminal; and a reinforcement tab integrally formed with said pressure contact tab, said reinforcement tab being bent so as to overlap a substantial portion of said intermediate portion.
Claim 7
Dependent Claim
21 words
