Abstract
Abstract An electrical connector (1) (see Fig. 1) which is to be surface-mounted to a printed circuit board (6) has terminals (11) with inverted "T"-shaped soldering portions (12) to be electrically connected to conductors on the printed circuit board (6) each by soldering its soldering portion (12) to a conductor. The soldering portion comprises a flat foot (17) and a leg (18) which is integrally connected to and rising from the midportion of said foot (17). The relatively large foot (17) has an effect of causing substantial reduction of load per unit soldering area upon application of an undesired force to the terminal (11) and of increasing the strength of the soldering joint against removal from the conductor of the printed circuit board (6).

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
90 words
Surface-mounted component's contact having a soldering portion, which contact is to be mounted to the surface of a printed circuit board (6) and is to be electrically connected to a conductor on said circuit board, characterized in that said soldering portion (12) comprises a flat foot (17) and a leg (18), which is integrally connected to and rising from the midportion of said foot (17), thus generally shaped in the form of an inverted "T", said soldering portion (12) being a metal piece made, e.g. by stamping a metal blank.
Claim 2
Dependent Claim
90 words
Surface-mounted component's contact having a soldering portion, which contact is to be mounted to the surface of a printed circuit board (6) and is to be electrically connected to a conductor on said circuit board, characterized in that said soldering portion (12) comprises a flat foot (17) and a leg (18), which is integrally connected to and rising from the midportion of said foot (17), thus generally shaped in the form of an inverted "T", said soldering portion (12) being a metal piece made, e.g. by stamping a metal blank.
Claim 3
Dependent Claim
52 words
Surface-mounted component's contact according to claim 1 wherein said flat foot (17) of said soldering portion (12) is rectangular, and said leg (18) is integrally connected to the midportion of said rectangular foot to rise upright thereform, said leg (18) having a width equal to the short side of said rectangular foot.
Claim 4
Dependent Claim
39 words
Surface-mounted component's contact according to claim 1 or 2 wherein said leg (18) is integrally connected to a trunk (13) which is integrally connected to a contact piece (14), thereby constituting together a terminal (11) of an electric connector.
Claim 5
Dependent Claim
47 words
Surface-mounted component's contact according to claim 3 wherein said trunk (13) has an arm (16) extending parallel to said contact piece (14) and integrally connected to said trunk (13), said arm (16) being adapted to be inserted in a selected slot (15) of an elongated body (4).
Claim 6
Dependent Claim
47 words
Surface-mounted component's contact according to claim 4 wherein said soldering portion (12) comprising said flat, rectangular foot (17) and said leg (18), said trunk (13), said contact piece (14) and said arm (16) are integrally connected together in a unitary form stamped out from a metal sheet.
Claim 7
Dependent Claim
54 words
Surface-mounted component's contact according to claim 5 wherein a pair of terminals (11) each stamped out from a metal sheet are arranged with their contact pieces (14) facing each other at a predetermined interval, and their feet positioned relative to one another to be soldered to a conductor on said printed circuit board (6).
