Abstract

Abstract A female terminal includes a cylindrical portion having an opening for insertion of a male terminal. The cylindrical portion contains an elastic contact portion for pressing the male terminal inserted through the opening against an inner wall of the cylindrical portion. The elastic contact portion has a first arm, a second arm, and a first vertex for connecting the first and the second arms. An end of the first arm is connected to the cylindrical portion in the vicinity of the opening thereof. The cylindrical portion is provided with a supporting portion for restricting a degree of deflection of the elastic contact portion. The supporting portion has a third arm to be brought into contact with the first arm of the elastic contact portion for restricting deflection of the elastic contact portion. Contact surfaces of the first and the third arms are adapted in shape to each other so as to assure tight contact therebetween.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 170 words
A female terminal for electrical connection with a male terminal, comprising: a cylindrical portion having an opening for insertion of said male terminal; an elastic contact portion contained in said cylindrical portion for pressing said male terminal inserted through said opening against an inner wall of said cylindrical portion, said elastic contact portion having a first arm, a second arm, and a first vertex connecting said first and said second arms, an end of said first arm being connected to said cylindrical portion in the vicinity of said opening thereof, an end of said second arm being a free end; and a supporting portion for restricting a degree of deflection of said elastic contact portion, said supporting portion having a third arm to be brought into contact with said first arm of said elastic contact portion to restrict deflection of said elastic contact portion; wherein contact surfaces of said first and said third arms are conformable to each other so as to assure close contact therebetween along the length thereof.
Claim 2
Dependent Claim 170 words
A female terminal for electrical connection with a male terminal, comprising: a cylindrical portion having an opening for insertion of said male terminal; an elastic contact portion contained in said cylindrical portion for pressing said male terminal inserted through said opening against an inner wall of said cylindrical portion, said elastic contact portion having a first arm, a second arm, and a first vertex connecting said first and said second arms, an end of said first arm being connected to said cylindrical portion in the vicinity of said opening thereof, an end of said second arm being a free end; and a supporting portion for restricting a degree of deflection of said elastic contact portion, said supporting portion having a third arm to be brought into contact with said first arm of said elastic contact portion to restrict deflection of said elastic contact portion; wherein contact surfaces of said first and said third arms are conformable to each other so as to assure close contact therebetween along the length thereof.
Claim 3
Dependent Claim 47 words
A female terminal as claimed in claim 1, wherein said elastic contact portion has an arched shape, said first and said second arm having a plate-like shape, an end of said first arm being integrally connected to said cylindrical portion in the vicinity of said opening thereof.
Claim 4
Dependent Claim 29 words
A female terminal as claimed in claim 1, wherein said supporting portion has an arched shape, said third arm being connected to a fourth arm through a second vertex.
Claim 5
Dependent Claim 39 words
A female terminal as claimed in claim 3, wherein said third and said fourth arms are formed into a plate-like shape, an end of each of said third and said fourth arms is integrally connected to said cylindrical portion.
