Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
261 words
A pin header comprising: a plurality of pin contacts (12A, 12B);
an insulating housing (13) generally of a parallelepiped shape and insert-molded
with the pin contacts each penetrating the housing, the pin contacts
(12A,12B)forming an upper row and a lower row in the insulating housing
(13), each pin contact composed of a plugging rod (14) extending horizontally
from a front face of the housing, a leg (15A,15B) and a generally
straight, rearward and horizontal extension (16), all integral with each other,
the plugging rod (14) protruding from a front face of the housing and having
a rear end that is exposed on a rear face of the housing (13), with the
rear end being bent downwards generally at a right angle to provide the leg
(15A,15B); and each leg having its lower end continuing at a right angle
either directly or indirectly to the rearward horizontal extension (16) that is
to be surface-mounted on a printed circuit board (P), characterized in that only those legs (15A) of the pin contacts (12A)
forming the upper row in the housing (13) have each an intermediate step
(19) at a corner between the leg (15A) and the horizontal extension (16), the
intermediate step (19) being formed by twice-bending each leg outwardly at
first at a right angle and then downwards also at a right angle, and in that the legs (15A) of the pin contacts (12A) forming the upper
row are embedded in the housing (13), with the intermediate step (19) of
each contact being exposed outside together with the rearward horizontal
extension (16).
Claim 2
Dependent Claim
31 words
A pin header as defined in claim 1, characterized in that each leg
(15A) in the upper row has its rear surface area exposed outsides and rearwardly
of the housing (13).
Claim 3
Dependent Claim
48 words
A pin header as defined in claim 1 or 2, characterized in that
wherein a shoulder (17) is formed in a middle region of the leg (15A,15B)
so as to render each leg and each rear straight extension (16) thinner than
the body of each plugging rod (14).
Claim 4
Independent Claim
256 words
A method for manufacturing a pin header, comprising the steps of: preparing pin contacts (12A,12B) whose rearward horizontal extensions
(16) to be surface-mounted on a printed circuit board (P) are arranged
at a predetermined pitch and in parallel with each other and are integrally
connected to a common crosspiece (18); setting the pin contacts (12A,12B) in an injection mold so as to form
therein an upper row and a lower row; and finally insert-molding an insulating housing (13) so that plugging rods
(14) of the contacts continue from respective legs (15A,15B) and protrude
forwardly of the housing, with the rearward extensions (16) continuing
from the legs and protruding rearwardly of said housing, characterized in that the contacts (12A) forming the upper row in the
housing (13) have each an intermediate step (19) at a corner between the leg
(15A) and the horizontal extension (16), wherein the intermediate step (19)
is formed by twice-bending each leg (15A) outwardly at first at a right
angle and then downwards also at a right angle, and in that during the step of insert molding the housing (13) each
contact (12A) forming the upper row is kept supported at four points in and
by the mold, that is, at its plugging rod (14), at its rear surface area of the
leg (15A), at its intermediate step (19) and at the crosspiece (18), whereby
the entirety of each leg (15A) except for its rear surface area supported on a
portion of the mold is embedded in the insulating housing (13) thus molded.
Claim 5
Dependent Claim
44 words
The method as defined in claim 4, characterized in that a shoulder
(17) is formed in a middle region of the leg (15A,15B) so as to render each
leg and each rear straight extension (16) thinner than the body of each plugging
rod (14).
