Circuit board connecting device

摘要

A circuit board connecting device comprising a first connector which having a first fixing metallic member attached to a first housing, a second connector having a second fixing metallic member attached to a second housing, and holding means operative to prevent the second housing from being undesirably separated from the first housing under a condition in which the first and second housings are coupled with each other, wherein end portions of a resilient movable holding member provided on the first connector to be movable in a predetermined direction are supported respectively by the first fixing metallic member to engage respectively with portions of the second fixing metallic member for holding the second housing when the second housing is coupled with the first housing, so that the end portions of the resilient movable holding member and the portions of the second fixing metallic member constitute the holding means.

1. A circuit board connecting device comprising;
a first connector which has a first insulating housing, a plurality of first contacts arranged on the first insulating housing, each of which is provided with a board connecting portion to be connected with a circuit terminal provided on a first circuit board, and a first fixing metallic member attached to the first insulating housing for fixing the first insulating housing to the first circuit board; a second connector which has a second insulating housing operative to be coupled with the first insulating housing, a plurality of second contacts arranged on the second insulating housing, each of which is provided with a board connecting portion to be connected with a circuit terminal provided on a second circuit board and is operative to come into contact with a corresponding one of the first contacts, and a second fixing metallic member attached to the second insulating housing for fixing the second insulating housing to the second circuit board; and holding means operative to hold the second insulating housing for preventing the same from being undesirably separated from the first insulating housing under a condition wherein the first and second insulating housings are coupled with each other, wherein a resilient movable holding member is provided on the first connector to elongate along a longitudinal direction of the first insulating housing with a pair of end portions thereof supported respectively by a couple of portions of the first fixing metallic member positioned respectively at a pair of end portions of the first insulating housing in its longitudinal direction and to be movable in a direction perpendicular to the longitudinal direction of the first insulating housing; wherein a pair of engaging portions are formed respectively on a couple of portions of the second fixing metallic member positioned respectively at a pair of end portions of the second insulating housing in its longitudinal direction; wherein the end portions of the resilient movable holding member supported by the first fixing metallic member are caused to engage respectively with the engaging portions formed on the second fixing metallic member for holding the second insulating housing when the second insulating housing is coupled with the first insulating housing, so that the end portions of the resilient movable holding member supported by the first fixing metallic member and the engaging portions formed on the second fixing metallic member constitute the holding means; and wherein the end portions of the resilient movable holding member supported by the first fixing metallic member are caused to disengage respectively from the engaging portions formed on the second fixing metallic member for releasing the second insulating housing from holding by the holding means when the resilient movable holding member is moved in the direction perpendicular to the longitudinal direction of the first insulating housing under a condition wherein the second insulating housing is held by the holding means.
