Card edge connector

摘要

A card edge connector includes supporting walls (31) provided along a plurality of juxtaposed terminal fittings (50) and configured to receive reaction forces from the side of a circuit board (62) due to a resilient pressing action of resilient contact pieces (54) and a front wall (33) connected to front end edges of the supporting walls (31). The front wall (33) is formed with a board insertion port (41) in the form of a slit-like opening substantially parallel to a juxtaposition direction of the terminal fittings (50) and communicating with a board accommodation space (40) and a coupling portion (44) configured to couple two long-side opening edges (43) substantially parallel to the supporting walls (31). The circuit board (62) is formed with a cut (65) configured to avoid interference with the coupling portion (44) in a state inserted in the board accommodation space (40).

主权项

1. A card edge connector assembly comprising:
a board-side connector that has a board-side housing and a circuit board attached to the board-side housing, the circuit board having a front edge region projecting from the board-side housing and having a plurality of contact portions and a cut portion in proximity to the front edge region; and a harness-side connector comprising: a housing main body formed with a receptacle configured to accommodate the board-side connector; and a terminal holding member inserted in the receptacle of the housing main body, the terminal holding member including:
a front wall;opposed supporting walls extending rearward from the front wall;a board accommodation space open into the front wall at a position between the supporting walls and configured to receive the front edge region of the circuit board;terminal accommodating chambers formed between the support walls and adjacent the board accommodation space, the terminal accommodating chambers being configured for accommodating a plurality of juxtaposed terminal fittings and configured so that the supporting walls receive reaction forces given to the terminal fittings from the circuit board due to a resilient pressing action of resilient contact pieces of the terminal fittings; anda coupling portion formed at the front wall portion and extending between the supporting walls; wherein the coupling portion is disposed to fit in the cut portion formed on the circuit board and is configured to resist the reaction forces given to the supporting walls by the terminal fittings when the circuit board is inserted in the board accommodation space.
