A pin header includes a connection pins and a pin holder. The connection pins includes one end to be connected to a first circuit board and the other end to be connected to a second circuit board which is positioned to form a given gap between the first circuit board and the second circuit board. The pin holder includes a holder body which holds centers of side faces of the plurality of connection pins, and a projection holder which includes a first projecting portion projecting from the holder body toward a side of the one end of the connection pins, and a second projecting portion projecting from the holder body toward a side of the other end of the connection pins. A projection length of the first projecting portion is equal to a projection length of the second projecting portion.
1. A pin header including:
a plurality of connection pins that includes one end to be connected to a first circuit board and the other end to be connected to a second circuit board which is positioned to form a given gap between the first circuit board and the second circuit board; and
a pin holder that includes:
a holder body which holds centers of side faces of the plurality of connection pins; and
a projection holder which includes a first projecting portion projecting from the holder body toward a side of the one end of the connection pins, and a second projecting portion projecting from the holder body toward a side of the other end of the connection pins
wherein a projection length of the first projecting portion is equal to a projection length of the second projecting portion,
wherein the first projecting portion and the second projection portion project from a portion of the holder body which is provided outwardly from the plurality of connection pins,
wherein the first projecting portion and the second projection portion have a smaller width respectively than a width of the holder body, and
wherein at least one of the connection pins has a projection length which is longer than a projection length of the first projecting portion and the second projection portion respectively.
2. The pin header according to claim 1 , wherein
the pin holder includes a plurality of the projection holders,
the holder body includes insertion holes into which the connection pins are inserted, and
the projection holders are placed symmetrically about a center of a surface of the holder body where the insertion holes are formed.
3. The pin header according to claim 1 , wherein
end portions of the first projecting portion and the second projecting portion are formed into a spherical shape.
4. The pin header according to claim 2 , wherein
end portions of the first projecting portion and the second projecting portion are formed into a spherical shape.
5. The pin header according to claim 1 , wherein the end portions of the first projecting portion are fixed to the first circuit board in point contact.
6. The pin header according to claim 2 , wherein the end portions of the first projecting portion are fixed to the first circuit board in point contact.
7. The pin header according to claim 3 , wherein the end portions of the first projecting portion are fixed to the first circuit board in point contact.
8. The pin header according to claim 4 , wherein the end portions of the first projecting portions are fixed to the first circuit board in point contact.
