ABSTRACT:
A female terminal metal fixture which can prevent a resilient contact tongue from being deflected over a wide range. A box-like body is provided on its right and left side walls with an inwardly bulged restrictive portion formed by a bulging process. Each restrictive portion extends longitudinally below a resilient contact tongue from the distal end of the tongue to the front end of the contact. When a tab is inserted into the insertion space slantwise, the tongue is deflected down by a distance greater than lo that in the case of a normal insertion. The first contact section of the tongue contacts the front corner of the restrictive portion, while the second contact section contacts the rear upper face of the portion. Thus, the tongue is prevented from being deflected beyond its elastic limit. Alternatively, the box-like body is provided on its side walls with an inwardly bulged restrictive portion extending longitudinally from an opening in the body to about the midpoint of the resilient tongue. The restrictive portion has an upper horizontal edge section at its rear, and an upper ascending slope edge section at its front. When the tab is inserted into the opening slanting downwardly, the distal end contacts the ascending slope and is prevented from reaching the tongue by the edge section. If the tab is further inserted into the opening, the distal end slides on the upper ascending slope and reaches the upper horizontal edge. Then, the tab slides on the horizontal edge and is directed to the correct horizontal position in the insertion space. This keeps deflection of the tongue within the elastic limit thereof and provides an elastic contact between the tab and the tongue.
