Card edge connector

摘要

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).

主权项

1. A card edge connector assembly comprising: a board-side connector with a board-side housing and a circuit board attached to the board-side housing, a plurality of contact portions juxtaposed on the circuit board; and
a harness-side connector that includes a terminal accommodating portion accommodating a plurality of terminal fittings in a state positioned in a juxtaposition direction for resiliently contacting the contact portions on the circuit board and a housing main body accommodating the terminal holding member therein and formed with resiliently deflectable locking lances for retaining the terminal fittings in the terminal holding member,wherein
a linear expansion coefficient of the terminal holding member is substantially equal to that of the circuit board and smaller than that of the housing main body.
