Board-to-board connector having a sidewall portion with a sloped guide surface with cut out
A board-to-board connector comprising a first connector and a second connector is disclosed. The first connector has a first housing. Each first fitting guide portion of the first housing is provided with a protrusive sidewall portion configured to define both sides of each concave guide portion of the first housing to be connected to each side wall portion of the first housing and protrude out from a fitting face of each side wall portion of the first housing. The protrusive sidewall portion is provided with a sloped guide surface formed at an entrance end of each concave guide portion of the first housing to be inclined with respect to a longitudinal direction of the first housing.
1. A board-to-board connector, the board-to-board connector comprising:
a first connector, the first connector including a first housing mounting therein first terminals, the first housing including:
an island portion;
concave insertion portions formed on both sides of the island portion;
side wall portions formed on both sides of each concave insertion portion;
first fitting guide portions connected to both ends in a longitudinal direction of each side wall portion; and
concave guide portions formed in each first fitting guide portion, and
a second connector configured to engage the first connector, the second connector including a second housing mounting therein second terminals configured to make contact with the first terminals, the second housing including:
a recessed cavity portion in which the island portion is inserted;
protrusive convex portions formed on both sides of the recessed cavity portion to be inserted in the concave insertion portions; and
second fitting guide portions connected to both ends in the longitudinal direction of each protrusive convex portion to be inserted in the concave guide portions;
wherein:
each first fitting guide portion is provided with a protrusive sidewall portion configured to define both sides of each concave guide portion to be connected to each side wall portion and protrude out from a fitting face of each side wall portion; and
the protrusive sidewall portion is provided with a sloped guide surface formed at an entrance end of each concave guide portion, the sloped guide surface forming a cut out of the protrusive sidewall portion, the plane of the cut out being oblique to a longitudinal direction of the first housing.
2. The board-to-board connector of claim 1 , wherein the sloped guide surface is formed in a boundary portion of the protrusive sidewall portion and the side wall portions so as to protrude out from the fitting face of each side wall portion.
3. The board-to-board connector of claim 2 , wherein the entrance end of each concave guide portion having formed therein the sloped guide surface has a shape that is obliquely opened as viewed from an upper side thereof.
4. The board-to-board connector of claim 3 , wherein each second fitting guide portion is provided with a sloped guided surface configured to be formed on each of both sides thereof and inclined with respect to a longitudinal direction of the second housing.
5. The board-to-board connector of claim 1 , wherein none of the portions of the first terminals protrude out from the fitting faces of the side wall portions and the island portion.
6. The board-to-board connector of claim 3 , wherein none of the portions of the second terminals protrude out from fitting faces of the protrusive convex portions.
7. The board-to-board connector of claim 6 , wherein each second fitting guide portion is provided with a sloped guided surface configured to be formed on each of both sides thereof and inclined with respect to a longitudinal direction of the second housing.
8. The board-to-board connector of claim 1 , wherein each second fitting guide portion is provided with a sloped guided surface configured to be formed on each of both sides thereof and inclined with respect to a longitudinal direction of the second housing.
