Card edge connector
It is aimed to provide a card edge connector capable of improving electrical conduction between a terminal and a board. A card edge connector ( 1 ) is provided with a housing ( 12 ) and a terminal fitting ( 13 ) including a base portion ( 13 A) to be fixed to the housing ( 12 ), a contact portion ( 13 D) to be brought into electrical contact with a circuit board ( 62 ) assembled with the housing ( 12 ) and a spring portion ( 13 C) provided between the base portion ( 13 A) and the contact portion ( 13 D) for displaceably supporting the contact portion ( 13 D).
1 . A card edge connector, comprising:
a housing; and
a terminal fitting including a base portion to be fixed to the housing, a contact portion to be brought into electrical contact with a board assembled with the housing and a spring portion provided between the base portion and the contact portion for displaceably supporting the contact portion,
the spring portion is accommodated in a box portion, and the box portion is inserted into a cavity of the housing.
2 . The card edge connector of claim 1 , comprising a box portion for accommodating the spring portion.
3 . The card edge connector of claim 2 , wherein:
the box portion is coupled to the base portion via the spring portion, and
a gap is provided between the box portion and the base portion.
4 . The card edge connector of claim 3 , wherein the gap is present in a direction orthogonal to a tolerance absorbing direction by the spring portion.
5 . The card edge connector of claim 3 , wherein the gap is present in a direction parallel to the tolerance absorbing direction by the spring portion.
6 . The card edge connector of claim 2 , comprising a locking portion connected to the contact portion and the spring portion, the locking portion locking the box portion.
7 . The card edge connector of claim 1 , wherein a plate thickness direction of the base portion is orthogonal to a tolerance absorbing direction by the spring portion.
8 . The card edge connector of claim 1 , wherein the spring portion includes an S-shaped portion.
9 . The card edge connector of claim 1 , wherein:
the contact portion includes a resilient contact portion projecting in a direction orthogonal to an assembling direction of the board with the housing, the resilient contact portion resiliently contacting the board, and
the spring portion and the resilient contact portion are arranged in the same direction as the assembling direction.
