Abstract
Abstract A tab receptacle terminal fabricated by bending a single sheet of electrically conductive material comprising a receptacle box having an end opening through which a male terminal is inserted so as to make contact with the receptacle box. The receptacle box includes a bottom, top, and sides, the top including a leaf spring which extends toward the bottom and may be formed with a terminal projection extending toward the bottom for engagement with a male terminal inserted into the receptacle box. Fixed beams formed on the bottom and extending toward the leaf spring for engagement with a male terminal with normal force applied by the leaf spring toward the bottom to complete the electrical connection.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
147 words
A tab receptacle terminal fabricated by bending a single sheet of material comprising: a rectangular receptacle box having a closed continuous wall forming an end opening through which a male terminal is inserted so as to make contact with said receptacle box, said receptacle box including a bottom, a top, and sides, single leaf spring means formed in said top so as to extend across substantially the entire width of said top between said sides, and extending toward said bottom for engagement with a male terminal inserted therebetween to achieve high retention forces, closed slots extending lengthwise along the juncture of said top with said sides to enable deflection of said leaf spring means, and fixed beams formed on said bottom and extending toward said leaf spring means for engagement with a male terminal with normal force applied by said leaf spring means toward said fixed beams.
Claim 2
Dependent Claim
147 words
A tab receptacle terminal fabricated by bending a single sheet of material comprising: a rectangular receptacle box having a closed continuous wall forming an end opening through which a male terminal is inserted so as to make contact with said receptacle box, said receptacle box including a bottom, a top, and sides, single leaf spring means formed in said top so as to extend across substantially the entire width of said top between said sides, and extending toward said bottom for engagement with a male terminal inserted therebetween to achieve high retention forces, closed slots extending lengthwise along the juncture of said top with said sides to enable deflection of said leaf spring means, and fixed beams formed on said bottom and extending toward said leaf spring means for engagement with a male terminal with normal force applied by said leaf spring means toward said fixed beams.
Claim 3
Dependent Claim
24 words
A tab receptacle terminal according to claim 1 wherein said beams are formed from portions of said bottom turned toward said single leaf spring.
Claim 4
Dependent Claim
37 words
A tab receptacle terminal according to claim 2 wherein said beams are formed with inclined end ramps adjacent the end opening of said receptacle box to facilitate the insertion of a male terminal into said receptacle box.
Claim 5
Dependent Claim
108 words
A tab receptacle terminal according to claim 1 wherein said leaf spring means comprises a portion of said top bowed forwardly and downwardly toward said bottom thence upwardly and terminating abruptly in an edge, a terminal projection on said leaf spring means extending toward said bottom, said terminal projection being located at the inner side of said leaf spring portion where said downward bowing terminates and said upward bowing commences, said edge being spaced from said end opening of said receptacle box and means on opposite sides of said edge spaced from said sides and formed integral with said top at said open end of said receptacle box.
Claim 6
Dependent Claim
44 words
A tab receptacle terminal according to claim 4 wherein said receptacle box includes slots located between said top and sides and on opposite sides of said leaf spring facilitating springing movement of said leaf spring in a direction toward and away from said bottom.
Claim 7
Dependent Claim
50 words
A tab receptacle terminal according to claim 1 further including interlocking tabs formed at opposite ends of the single sheet of material forming said receptacle box, said interlocking tabs being located at the juncture of top wall and a side wall and at opposite ends of said leaf spring means.
Claim 8
Dependent Claim
27 words
A tab receptacle terminal according to claim 6 further including stabilizing nibs on said bottom to one side of said fixed beams and opposite said interlocking tabs.
Claim 9
Dependent Claim
102 words
A tab receptacle terminal fabricated by bending a single sheet of material comprising: a rectangular receptacle box having a closed continuous wall forming an opening through which a male terminal is inserted so as to make contact with said receptacle box, a portion of said box being shaped to form a single flexible leaf spring means for engagement with a male terminal inserted into said box through said end opening and contact means on said box extending toward said leaf spring means for engagement with a male terminal engaged with normal force applied by said leaf spring means toward said contact means.
Claim 10
Dependent Claim
102 words
A tab receptacle terminal fabricated by bending a single sheet of material comprising: a rectangular receptacle box having a closed continuous wall forming an opening through which a male terminal is inserted so as to make contact with said receptacle box, a portion of said box being shaped to form a single flexible leaf spring means for engagement with a male terminal inserted into said box through said end opening and contact means on said box extending toward said leaf spring means for engagement with a male terminal engaged with normal force applied by said leaf spring means toward said contact means.
Claim 11
Dependent Claim
137 words
A tab receptacle terminal fabricated by bending a single sheet of material comprising: a rectangular receptacle box having a closed continuous wall forming an end opening through which a male terminal is inserted so as to make contact with said receptacle box, said receptacle box including a bottom, a top, and sides, said bottom and top being return bent upn themselves at said opening and terminating in edge abutments located above and below said top and bottom, respectively, single leaf spring means formed in said top and extending toward said bottom for engagement with a male terminal inserted therebetween to achieve high retention forces and fixed beams formed on said bottom and extending toward said leaf spring means for engagement with a male terminal with normal force applied by said leaf spring means toward said fixed beams.
Claim 12
Dependent Claim
137 words
A tab receptacle terminal fabricated by bending a single sheet of material comprising: a rectangular receptacle box having a closed continuous wall forming an end opening through which a male terminal is inserted so as to make contact with said receptacle box, said receptacle box including a bottom, a top, and sides, said bottom and top being return bent upn themselves at said opening and terminating in edge abutments located above and below said top and bottom, respectively, single leaf spring means formed in said top and extending toward said bottom for engagement with a male terminal inserted therebetween to achieve high retention forces and fixed beams formed on said bottom and extending toward said leaf spring means for engagement with a male terminal with normal force applied by said leaf spring means toward said fixed beams.
