Abstract
An electronics module having a latch assembly including first and second reciprocating latch portions adapted to engage respective first and second opposite edges of a mounting rail. Each of the latch portions includes a locking tab, the locking tabs movable away from each other from a latched position to an unlatched position, the first and second latch portions being coupled together for reciprocating motion, at least one of said latch portions including an actuator portion extending from the housing for manual actuation of the latch assembly between the latch and unlatched positions.
Claims20
An electronics module comprising:
- a housing including a rear face having a recess adapted to receive an associated mounting rail, said recess having first and second opposite edges;
- a latch assembly connected to said housing and adapted for selectively releasably securing said housing an associated mounting rail located in said recess, said latch assembly including:
- a first latch portion movably connected to said housing and comprising a locking tab adapted to capture a first associated DIN rail flange in said recess;
- a second latch portion movably connected to said housing adjacent said first latch portion and comprising a second locking tab adapted to capture a second associated DIN rail flange in said recess;
- said first and second latch portions movable relative to each other to and between:
- (i) a latched configuration where said first and second latch portions are located in respective latched positions in which said first and second locking tabs project respectively beyond said first and second opposite edges of said recess and partially obstruct said recess;
- and (ii) an unlatched configuration where said first and second latch portions are located in respective unlatched positions in which said first and second locking tabs are spaced farther apart from each other as compared to the latched configuration;
- said first and second latch portions coupled together for opposite reciprocating movement between said latched and unlatched positions.
An electronics module comprising:
- a housing having a recess adapted to receive an associated mounting rail, said recess having first and second opposite edges;
- and
- a latch assembly adapted to selectively secure the housing to the associated mounting rail;
- said latch assembly including first and second reciprocating latch portions mounted in the housing and adapted to engage respective first and second opposite edges of the associated mounting rail, each of the latch portions including a locking tab configured to extend into the recess to engage the associated mounting rail, said locking tabs movable away from each other from a latched position to an unlatched position, said first and second latch portions being coupled together for reciprocating motion, at least one of said latch portions including an actuator portion extending from the housing for manual actuation of the latch assembly between the latch and unlatched positions, the actuator portion adapted to engage structure of the housing when the locking tabs are in the unlatched position to restrict movement of the latch assembly from the unlatched position.
