Integrated DIN rail attachment feature for superior attachment

Abstract

An electronics module includes a base and a cover connected to the base. The base includes a recess adapted to receive an associated mounting rail. At least one fixed rail constraining tab is located adjacent a first edge of the recess and is adapted to engage a first flange of the associated mounting rail. First and / or second latch arms are located adjacent a second edge of the recess that is opposite the first edge of the recess. The first and second latch arms are connected to a fixed portion of the second edge and project outwardly relative to opposite lateral sides of the fixed portion. Each of the first and second latch arms includes a rail capture tab. The first and second latch arms are selectively movable resiliently to and from latched and unlatched positions, wherein the rail capture tabs of the first and second latch arms project beyond the fixed portion of the second edge and into the recess when the first and second latch arms are located in their respective latched positions, and wherein the rail capture tabs of the first and second latch arms are withdrawn relative to the fixed portion of the second edge when the first and second latch arms are located in their respective unlatched positions. The cover or other portion of the module defines first and second receiving locations that receive and retain portions of the first and second latch arms when the first and second latch arms are located in their respective latched positions.

Description

Technical field [0001] The present invention relates to an electronic module with attachment parts, and in particular to an integrated DIN rail attachment part for good attachment. Background technique [0002] It is known to provide an electronic module with attachment parts for releasably fixing the module on a DIN rail, which is an industry standard mounting structure. Known DIN rail attachment parts include one or more latches, which are manufactured to be separated from the electronic module and movably connected to the module. After being assembled to the module, this latch can be used in the unlocking position for connecting / disconnecting the module to the DIN rail and the latch for fixing the module to the DIN rail immovably The positions are manually slid or moved. This type of attachment part is usually effective, but one or more latches need to be separately constructed (for example, injection molded) and then assembled on the module, which increases product cost.
