Abstract: It is aimed to prevent a reduction of contact reliability. A card edge connector (A) includes a first housing (10) formed with a board accommodation space (16) open forward, terminal fittings (17) provided in the first housing (10) and formed with resilient contact portions (18) projecting toward the board accommodation space (16), a second housing (20) including a circuit board (23) to be inserted into the board accommodation space (16) from front of the first housing (10), and guide slopes (36) made of synthetic resin, provided to cover a leading edge of the circuit board (23) in an inserting direction into the board accommodation space (16) and inclined with respect to the inserting direction into the board accommodation space (16).

Abstract: 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).

Abstract: A card edge connector includes a harness-side connector (H) in which a plurality of terminal fittings (50) are juxtaposed in a harness-side housing (10) and a board-side connector (P) in which a circuit board (62) is attached to a board-side housing (60). When the two housings (10, 60) are connected, the plurality of terminal fittings (50) are resiliently brought into contact with a plurality of contact portions (64) juxtaposed on the circuit board (62). The harness-side housing (10) includes a terminal accommodating portion (39) for accommodating the plurality of terminal fittings (50) in a state positioned in a juxtaposition direction, and at least a part of the terminal accommodating portion (39) is made of a material having a linear expansion coefficient substantially equal to that of a material of the circuit board (62).

Abstract: A card edge connector includes a harness-side connector (H) in which a plurality of terminal fittings (50) are arranged side by side in a harness-side housing (10) and a board-side connector (P) in which a connecting edge portion (63) of a circuit board (62) projects from a front surface (60F) of a board-side housing (60). The harness-side housing (10) includes a terminal accommodating portion (39) configured to accommodate the plurality of terminal fittings (50), and a housing accommodating portion (48) arranged to face a front surface (39F) of the terminal accommodating portion (39) and configured to accommodate the board-side housing (60) connected to the harness-side housing (10). A resilient member (49) configured to bias the terminal accommodating portion (39) and the board-side housing (60) in a direction toward or away from each other in parallel to a connecting direction is provided in the housing accommodating portion (48).
