Mounting rail and module latching system

摘要

A module latching arrangement for mounting and dismounting on a generally U-shaped support rail at least two module base bodies arranged orthogonally above and extending transversely across the support rail, each of the base bodies having a pair of bottom corner portions arranged on opposite sides of the support rail. At least one foot member is connected for horizontal longitudinal sliding movement relative to one of the base body corner portions relative to the adjacent support rail horizontal flange portion. A lateral displacement arrangement on the foot member is operable, when the foot member is displaced from a locked position toward an unlocked position relative to the support rail, to displace the first base body laterally away from an adjacent second base body mounted on the support rail. The foot member is latched in either a locked or an unlocked position relative to the base member.

主权项

1. A module latching arrangement for mounting and dismounting a plurality of parallel electrical modules in a row relative to a support rail, comprising:
a generally U-shaped support rail (2) having a horizontal base portion (23), a pair of vertical parallel leg portions (24) extending upwardly from the opposed side edges of said base portion, and a pair of horizontal flange portions (22) extending outwardly from the upper edges of said leg portions; at least two base members (4) arranged in side-by-side relation orthogonally above and extending transversely across said support rail, each of said base members having a horizontal bottom edge portion seated intermediate its ends on said support rail; at least one foot member (3) connected with the bottom edge end portion of a first one of said base members for horizontal longitudinal sliding movement transversely of said rail between locked and unlocked positions relative to the adjacent support rail flange portion; and a lateral displacement arrangement including:
a resilient shifting arm (35) longitudinally arranged on a side wall of said one foot member that is adjacent to said second base member, said shifting arm having a projection (351) on an inner side of said side wall; anda ramp surface (45) on an outer side of said first base member, wherein said ramp surface is engaged by said shifting arm projection when said foot member is displaced from said locked position toward said unlocked position, said ramp surface being inclined so as to effect outward displacement of said resilient shifting arm into said adjacent second base member, to thereby separate said first base member from said second base member.
