Abstract

A carrier rail housing ( 1 ) is described comprising a snap-in base ( 2 ) for setting on a carrier rail ( 3 ). The snap-in base ( 2 ) comprises a carrier rail receiving opening ( 5 ) for receiving a carrier rail ( 3 ), two snap-in latches ( 4, 12 ) movable relative to each other comprising respectively at least one snap-in lug ( 6, 13 ), which protrude in a snap-in position into the carrier rail receiving opening ( 5 ) for locking with a carrier rail ( 3 ) receivable in the carrier rail receiving opening ( 5 ), and a coupling element ( 10 ) which is in operative connection with the two snap-in latches ( 4, 12 ) and transfers a movement of one snap-in latch ( 4 ) into a movement of the other snap-in latch ( 12 ). The snap-in base ( 2 ) further comprises a locking arm ( 15 ) with a stop ( 18 ) protruding into the carrier rail receiving opening ( 5 ) in an open position, in which the snap-in lugs ( 6, 13 ) are unlocked from the carrier rail ( 3 ), for applying at a side edge of the carrier rail ( 3 ) receivable in the carrier rail receiving opening ( 5 ). The locking arm ( 15 ) is in an operative connection with the snap-in latches ( 4, 12 ) in such a way that the snap-in latches ( 4, 12 ) are held in the open position by the application of the stop ( 18 ).

First claim

The invention claimed is:

1. A carrier rail housing having a latching base for attaching to a carrier rail, wherein the latching base comprises
a carrier rail receiving opening for receiving the carrier rail,
two latching links that can move relative to one another having in each case at least one latching lug that protrudes in a latched position into the carrier rail receiving opening so as to latch with the carrier rail that can be received in the carrier rail receiving opening, and
a coupling element that is operatively connected to the two latching links and a movement of one latching link is transferred into a movement of the other latching link, characterized in that the latching base furthermore comprises a locking arm having a stop that protrudes into the carrier rail opening in an open position, in which the latching lugs are unlatched from the carrier rail, so as to make contact with a side edge of the carrier rail that can be received in the carrier rail receiving opening, wherein the locking arm is operatively connected to the latching links in such a manner that the latching links are held in the open position by means of the stop making contact.

2. The carrier rail housing as claimed in claim 1 , characterized in that the locking arm is formed with one of the latching links in an integral manner.

3. The carrier rail housing as claimed in claim 1 , characterized in that the locking arm is elastically resilient.

4. The carrier rail housing as claimed in claim 1 , characterized in that a resilient element is operatively connected between the carrier rail housing and at least one of the latching links in order to return the latching links under resilient force of the resilient element from an open position in the direction towards the latched position.

5. The carrier rail housing as claimed in claim 1 , characterized in that the carrier rail housing and the locking arm comprise guiding contours that are coordinated with one another and lie one on top of the other, wherein the guiding contours are embodied so as to displace the stop from a first region that lies between the carrier rail that is introduced into the carrier rail receiving opening, and the base of the carrier rail receiving opening into a second region that lies between a side wall of the carrier rail receiving opening and a side edge of the carrier rail if the latching lugs of the two latching links are moved away from one another from the latched position into the open position.

6. The carrier rail housing as claimed in claim 1 , characterized in that the stop of the locking arm is arranged on a support that can be positioned in the latched position between the carrier rail and the base of the carrier rail receiving opening.

7. The carrier rail housing as claimed in claim 1 ,
characterized in that the coupling element is a rotating disc that is mounted in such a manner that it can rotate about a rotary shaft that extends in the direction of extension of the carrier rail that can be received in the carrier receiving opening, wherein the latching links are connected in an articulated manner to one another lying on opposite sides of the rotating disc with the rotary shaft that lies between said latching links.

8. The carrier rail housing as claimed in claim 7 , characterized in that the latching links are connected in an articulated manner to the rotating disc and lie diametrically opposite one another.

9. The carrier housing as claimed in claim 1 , characterized in that the latching lugs in each case have an inclined surface that extends at an acute angle with respect to the opening plane of the carrier rail receiving opening.

10. The carrier rail housing as claimed in claim 1 having at least one circuit board and electronics system and having at least one plug element having conductor connecting contacts for connecting electrical conductors and said plug element can be connected in an electrically conductive manner to the circuit board.

11. The carrier rail housing as claimed in claim 10 , characterized in that the carrier rail housing is a device module of a modular control device, in particular an input module, an output module, a motor control module, an interface module, a field bus coupler or field bus controller having a computer unit for implementing a control program.
