Abstract

A female terminal is described which comprises a main body with a pair of opposed elastic clamping portions and a cylindrical sleeve which is inserted onto the main body. Inclined surfaces are provided in the opposite edges of each of the free ends of the elastic clamping portions so that the opposite edges do not abut the inner wall of the sleeve, when a male terminal is inserted into the female terminal.

Claims

1. A female terminal comprising:

a main body having a pair of opposed elastic clamping portions;

a cylindrical sleeve into which said main body and pair of opposed elastic clamping portions are inserted; and

guiding portions of said elastic clamping portions being formed with an inner peripheral wall surface which is of greater extent than an outer peripheral wall surface thereof, and opposite sides of said inner and outer peripheral wall surfaces being connected by edges whose surfaces inclinedly extend between said inner and outer wall surfaces so that the opposite edges do not contact an inner wall of said sleeve when a male terminal is inserted into the female terminal.

2. The female terminal as set forth in claim 1, wherein inclined surfaces are formed at the intersection of front end portions and the opposite edges of each of the guiding portions of said elastic clamping portions.

3. The female terminal as set forth in claim 1, wherein the outer peripheral walls of the guiding portions of said pair of opposed elastic clamping portions are formed into circular arc shapes and each of the outer peripheral walls has a radius of curvature larger than the inner radius of said sleeve.

4. The female terminal as set forth in claim 2, wherein inclined surfaces are formed at the intersection of front end portions and the opposite edges of each of the guiding portions of said elastic clamping portions.

5. A female terminal comprising:

a main body having a pair of opposed elastic clamping portions;

a cylindrical sleeve into which said main body and pair of opposed elastic clamping portions are inserted; and

overall opposite edges of said elastic clamping portions being formed with an inner peripheral wall surface which is of greater extent than an outer peripheral wall surface thereof, and opposite sides of said inner and outer peripheral wall surfaces being connected by edges whose surfaces inclinedly extend between said inner and outer wall surfaces so that the opposite edges do not contact an inner wall of said sleeve, when a male terminal is inserted into the female terminal.

6. The female terminal as set forth in claim 5, wherein the outer peripheral walls of said pair of opposed elastic clamping portions are formed into circular arc shapes and each of the outer peripheral walls has a radius of curvature larger than the inner radius of said sleeve.
