Abstract
Abstract To provide a beam welding terminal structure which holds a connection member to be connected, such as a wire, from opposite sides thereof, and firmly welds the connection member by irradiation of a beam such as a laser beam, a beam welding terminal structure includes holding walls at opposite sides, and a connection member to be connected is welded to the holding walls by irradiation of a beam. A projection extends from at least one of the holding walls and beyond the connection member in a direction of the height. A rectangular wave-shaped base wall has longitudinal side portions, extending in a direction intersecting the connection member, and transverse side portions extending parallel to the connection member. The holding walls each having the projection are formed respectively on the plurality of transverse side portions, and a pair of opposed holding walls are disposed respectively on opposite sides of the connection member, and are formed on one of the longitudinal side portions or each of more than one of the longitudinal side portions. In another form of structure, central portions of the pair of holding walls are bent inwardly to provide a reduced-width portion, and the reduced-width portion has projections extending beyond the connection member in a direction of the height, and the projection and the holding wall are interconnected by a mountain-like curved guide portion.

Claim 1
Independent Claim
143 words
In a beam welding terminal structure, having holding walls for a connection member to be connected, in which said holding walls are formed respectively at opposite sides, wherein one of said holding walls and said connection member are welded, the improvement in which a projection for fusion purposes is formed on at least one of said holding walls, and extends beyond said connection member in a direction of height, in which a rectangular wave-shaped bent base wall has longitudinal side portions, extending in a direction intersecting said connection member, and transverse side portions extending parallel to said connection member; said holding walls each having said projection are formed respectively on said plurality of transverse side portions; and at least one holding wall is disposed on one side of said connection member and is formed on at least one of said longitudinal side portions.
Claim 2
Dependent Claim
143 words
In a beam welding terminal structure, having holding walls for a connection member to be connected, in which said holding walls are formed respectively at opposite sides, wherein one of said holding walls and said connection member are welded, the improvement in which a projection for fusion purposes is formed on at least one of said holding walls, and extends beyond said connection member in a direction of height, in which a rectangular wave-shaped bent base wall has longitudinal side portions, extending in a direction intersecting said connection member, and transverse side portions extending parallel to said connection member; said holding walls each having said projection are formed respectively on said plurality of transverse side portions; and at least one holding wall is disposed on one side of said connection member and is formed on at least one of said longitudinal side portions.
Claim 3
Dependent Claim
85 words
In a beam welding terminal structure, having holding walls for a connection member to be connected, in which said holding walls are formed respectively at opposite sides, wherein one of said holding walls and said connection member are welded together, the improvement in which a projection for fusion purposes is formed on at least one of said holding walls, and extends beyond said connection member in a direction of height, wherein a plurality of projections are arranged in a staggered manner on the holding walls.
Claim 4
Dependent Claim
85 words
In a beam welding terminal structure, having holding walls for a connection member to be connected, in which said holding walls are formed respectively at opposite sides, wherein one of said holding walls and said connection member are welded together, the improvement in which a projection for fusion purposes is formed on at least one of said holding walls, and extends beyond said connection member in a direction of height, wherein a plurality of projections are arranged in a staggered manner on the holding walls.
Claim 5
Dependent Claim
87 words
A beam welding structure, comprising: a terminal body including a bottom wall and a pair of opposing side walls defining a space therebetween in which a connection member is received, said connection member extending in a longitudinal direction, wherein at least one of said side walls includes a projection extending therefrom, the width of said projection in said longitudinal direction being less than a corresponding width of said at least one side wall, wherein said connection member is welded to the terminal body by melting said projection.
Claim 6
Dependent Claim
87 words
A beam welding structure, comprising: a terminal body including a bottom wall and a pair of opposing side walls defining a space therebetween in which a connection member is received, said connection member extending in a longitudinal direction, wherein at least one of said side walls includes a projection extending therefrom, the width of said projection in said longitudinal direction being less than a corresponding width of said at least one side wall, wherein said connection member is welded to the terminal body by melting said projection.
Claim 7
Dependent Claim
43 words
The beam welding structure of claim 3, wherein said at least one side wall and said projection are deformed inwardly toward the other of said side walls so as to define a bend extending in a transverse direction, perpendicular to said longitudinal direction.
Claim 8
Dependent Claim
16 words
The beam welding structure of claim 3, wherein both of said side walls include said projection.
Claim 9
Dependent Claim
13 words
