Abstract

A female connector terminal includes a connector terminal body, which has a positioning portion on the middle for positioning in an electrically insulative member, a bonding portion at the rear side for bonding to a circuit board, and a tubular contact portion at the front side that has a receiving contact hole for receiving a rod-like metal contact of a male connector terminal, an annular groove extending around the periphery, and a longitudinal split, and a clamping shell clamped on the periphery of the tubular contact portion within the annular groove to enhance contact connection between the tubular contact portion and the inserted male connector terminal and having a locating portion fastened to the longitudinal slit to prohibit rotation of the clamping shell relative to the tubular contact portion.

Claims

1. A female connector terminal comprising a connector terminal body for receiving a rod-like metal contact of a male connector terminal and a clamping shell clamping on said connector terminal body to enhance connection between said connector terminal body and said rod-like metal contact of said male connector terminal that is inserted in said connector terminal body, wherein said connector terminal body comprises a positioning portion for positioning in an electrically insulative member, a bonding portion axially extending from one end of said positioning portion for bonding to a circuit board, and a tubular contact portion axially extending from an opposite end of said positioning portion, said tubular contact portion comprising a receiving contact hole for receiving said rod-like metal contact of said male connector terminal, an annular groove extending around the periphery thereof, and at least one longitudinal split extending along the length thereof in communication between said receiving contact hole and said annular groove;

said clamping shell defines a receiving space, which receives said tubular contact portion, a longitudinal crevice extending through the length thereof, and a locating portion protruded from one end thereof for fastening to said at least one longitudinal slit to prohibit rotation of said clamping shell relative to said tubular contact portion.

2. The female connector terminal as claimed in claim 1, wherein said tubular contact portion has an outer diameter gradually reducing in direction away from said positioning portion.

3. The female connector terminal as claimed in claim 1, wherein said tubular contact portion of said connector terminal body has a beveled guide edge at a front end of said receiving contact hole.

4. The female connector terminal as claimed in claim 1, wherein said tubular contact portion of said connector terminal body has a tapered face extending around one end of said annular groove and abutted against said positioning portion, and stop flange extending around an opposite end of said annular groove for stopping said clamping shell in said annular groove.

5. The female connector terminal as claimed in claim 1, said clamping shell has an annular shape.

6. The female connector terminal as claimed in claim 1, wherein said locating portion of said clamping shell comprises at least one hook block suspending from one end thereof for hooking in one of said at least one longitudinal split of said tubular contact portion, and two end notches at two opposite sides of each of said at least one hook block.
