Header and connector using header
View Patent ↗A header-side holding metal fitting is provided with lock piece portions, which are movable in a width direction X of a connector (a header housing) relative to a connection piece (a base portion) of the header-side holding metal fitting. The lock piece portions are lockable to lock holes (lock portions) which are formed in regions of a socket housing (a socket body) opposed to the lock piece portions when the socket housing and a header housing (a header body) are in an engaged state.
1. A header comprising a header body, on which header-side terminals and a header-side holding metal fitting are disposed, and being configured to engage the header body with a socket body, on which at least socket-side terminals are disposed, and thereby to bring the socket-side terminals and the header-side terminals into contact, wherein
the header-side holding metal fitting includes a base portion and a lock piece portion projects from the base portion in a length direction of the header body, the lock piece portion being movable in a width direction of the header body relative to the base portion of the header-side holding metal fitting,
the lock piece portion having a tip end portion, the tip end portion is lockable to a lock portion formed in a region of the socket body opposed to the tip end portion when the socket body and the header body are in an engaged state, and
the tip end portion of the lock piece portion is bent outward in the width direction of the header body.
2. The header according to claim 1 , wherein the lock piece portion of the header-side holding metal fitting is provided on two sides or one side of a peripheral wall portion in the width direction of the header body so as to be situated in a line with the header-side terminals.
3. The header according to claim 1 , wherein the header-side holding metal fitting includes a first lock piece portion and a second lock piece portion, which project substantially into an inverted V shape from the base portion.
4. The header according to claim 1 , wherein
the lock piece portion includes a first lock piece portion which projects from one end portion of the base portion and a second lock piece portion which projects from another end portion of the base portion, and
the header-side holding metal fitting is formed substantially into an inverted U shape by using the base portion, the first lock piece portion, and the second lock piece portion.
5. The header according to claim 1 , wherein
the lock piece portion projects from any of one end portion and a substantially central portion of the base portion,
the header-side holding metal fitting is formed substantially into any of an L shape and a T shape by using the base portion and the lock piece portion, and
the header uses one or a plurality of the header-side holding metal fittings each including the single lock piece portion.
6. The header according to claim 1 , wherein the lock piece portion is bent substantially into an S shape.
7. The header according to claim 1 , wherein the tip end portion of the lock piece portion is formed by being bent parallel to the width direction of the header body.
8. The header according to claim 1 , wherein
the lock piece portion and each lock portion are respectively provided with lock surfaces which come into contact when the socket body and the header body that are in the engaged state move in pullout directions, and
a restraint portion to restrain disengagement between the socket and the header is formed on at least any one of the lock surface of the lock portion and the lock surface of the lock piece portion.
9. The header according to claim 8 , wherein
the lock surface of the lock piece portion is formed into an inclined surface which rises toward the lock surface of the lock portion, and
the inclined surface serves as the restraint portion.
10. The header according to claim 8 , wherein
the lock surface of the lock piece portion and the lock surface of the lock portion are disposed parallel to each other, and
the pair of the lock surfaces disposed opposite and parallel to each other serve as the restraint portion.
11. The header according to claim 1 , wherein
a strut member is provided between the lock piece portion and a circuit board on which the header is to be mounted.
12. A connector comprising the header according to claim 1 .
