Abstract

A movable member ( 30 ) provided in a housing ( 10 ) is formed with a cover ( 32 ) configured to cover inserting edges ( 45 ) on a tip of a circuit board ( 41 ) in an inserting direction into a board accommodation space ( 15 ) when the circuit board ( 41 ) is inserted into the board accommodation space ( 15 ) and a receiving surface ( 34 ) configured to move the movable member ( 30 ) integrally with the circuit board ( 41 ) to a back side of the board accommodation space ( 15 ) by being pushed by the circuit board ( 41 ). The movable member ( 30 ) and the circuit board ( 41 ) are formed with locks ( 38, 46 ) configured to move the movable member ( 30 ) integrally with the circuit board ( 41 ) in a withdrawing direction from the board accommodation space ( 15 ) by locking each other.

First claim

The invention claimed is:

1. A card edge connector, comprising:
a circuit board;
a housing;
a board accommodation space formed in the housing and configured such that the circuit board is inserted thereinto from front of the housing;
a terminal fitting mounted in the housing;
a resilient contact piece provided on the terminal fitting and capable of resiliently contacting the circuit board inserted into the board accommodation space;
a movable member provided in the housing;
a cover formed on the movable member and configured to cover an inserting end edge portion on a tip of the circuit board in an inserting direction into the board accommodation space when the circuit board is inserted into the board accommodation space;
a guide configured to guide the movable member movably between an initial position where the cover is located at an entrance of the board accommodation space forward of the resilient contact piece and a connection position where the cover is located backward of the resilient contact piece;
a receiving surface formed on the movable member and configured to move the movable member integrally with the circuit board to a back side of the board accommodation space by being pushed by the circuit board; and
locking portions formed on the circuit board and the movable member to be lockable to each other and configured to move the movable member integrally with the circuit board in a withdrawing direction from the board accommodation space.

2. The card edge connector of claim 1 , wherein the receiving surface is formed on the cover.

3. The card edge connector of claim 1 , wherein:
the movable member is formed with a deflectable locking piece; and
the housing is formed with a holding portion configured to hold the movable member at the initial position by locking the deflectable locking piece.

4. The card edge connector of claim 3 , wherein:
the cover is long and narrow along the board accommodation space; and
two deflectable locking pieces connected respectively to both end parts of the cover.
