A terminal fitting (10) has a main body (11) and stabilizer (17) for preventing upside-down insertion stands up from a surface of the main body (11). Elongated projections (50) extend from a surface of the main body (11) opposite the stabilizer (17). If the male terminal fitting (10) is inserted upside down, the elongated projections (50) contact a bottom wall (24B) at the entrance of a cavity (24) during the insertion to shift the male terminal fitting (10) transversely. Thus, the stabilizer (17) is caught deeply by a ceiling wall (24C) at the entrance. As a result, the male terminal fitting (10) is prevented from any further insertion.

1. Field of the Invention
The invention relates to a terminal fitting and to a connector having a function of preventing the upside-down insertion of a terminal fitting.
2. Description of the Related Art
FIG. 1 is a longitudinal sectional view of a connector according to the invention, and showing a state before a male terminal fitting is inserted.
FIG. 2 is a side view of the male terminal fitting.
FIG. 3 is a plan view of the male terminal fitting.
A male connector according to the invention includes male terminal fittings 10, as shown in FIGS. 1 to 5. Each male terminal fitting 10 has a rectangular tubular main body 11 and a tab 12 that projects forward from the main body 11. Crimping barrels 13 are at the rear of the main body 11 and are configured for connection with an end of a wire W.
First and second engaging portions 14 and 15 project from the upper surface of the main body 11 as shown in FIGS. 2 and 5. The first engaging portion 14 is distanced slightly from the leading end of the upper surface and the second engaging portion 15 is at the rear end thereof. A recess 16 is formed behind the first engaging portion 14 and between the first and second engaging portions 14, 15 (FIG. 3). Further, a stabilizer 17 stands up at one edge of the rear end of the upper surface of the main body 11.
The connector also includes a housing 20 formed e.g. of a synthetic resin. The housing 20 has a main body 21 with a receptacle 22 into which a mating female connector housing (not shown) is fittable. Cavities 24 are arranged in upper and lower stages in the main body 21 and extend forward and backward. Each cavity 24 has a front wall 24A and a terminal insertion opening 25 extends through each front wall 24A. Each cavity 24 is configured to accommodate one of the male terminal fittings 10 so that the tab 12 of the male terminal fitting 10 passes through the terminal insertion opening 25. A lock 26 is provided at a front end of a bottom wall 24B of each cavity 24 for partly locking the male terminal fitting 10 that has been properly inserted. The bottom walls 24B of the cavities 24 at the upper stage also are ceiling walls 24C of the cavities 24 at the lower stage.
