ABSTRACT:
A thru-hole insertable terminal (10, 50, 60) includes an upper shank portion (12, 52, 66) preferably adapted for soldered securement to an end electrode (24) of a component (20), such as a capacitor. A lower shank portion (14, 54, 68) is dimensioned and adapted for minimal initial contact insertion into, and the temporary securement thereafter within, an oversized thru-hole (26, 58, 62) of a supporting substrate, such as a circuit board (28, 59, 64). At least one upwardly extending free-ended tab (32, 56, 72, 74) is formed in the lower terminal shank portion (14, 54, 68), and is oriented in the major plane thereof until after the insertion thereof within an associated substrate-formed thru-hole (26, 58, 62). Stop means (14b, 14c, 54b, 54c, 68b, 68c) also formed in the lower terminal shank portion is adapted to position the upper free end of the tab at an elevation preferably below the upper open end of a confining thru-hole. The tab (32, 56, 72, 74) is also dimensioned such that, when thusly positioned, the lower integral end thereof extends at least to the lower open end of the thru-hole. This results in the upper free end of the tab being pivoted against the sidewall of the confining thru-hole in response to a then downwardly protruding end region (14d, 54d, 68d) of the lower terminal shank portion being clinched against the underside of the supporting substrate (28, 59, 64). The thusly pivoted tab advantageously not only facilitates the temporary securement of the terminal within the associated thru-hole, but the establishment thereafter of a reliable, permanent soldered connection therebetween.
