Plug-in module for plugging in and/or pulling out of a module rack
US 6916190 B2
A plug-in module to be plugged in and/or pulled out of a module rack provided with at least one front stop edge, comprising a lever pull with handle arm and lever arm which is positioned pivoting in the frontal region of the plug-in module. A locking lever is attached articulated and such that it can rotate to the handle arm of lever pull. The locking lever turns an elastic locking tab. A corresponding locking profile is arranged in the frontal region of the plug-in module, wherein the locking tab engages behind the locking profile if the lever pull is pivoted out completely and thus prevents the lever pull from pivoting.
a locking lever is attached such that it can rotate on the handle arm of the lever pull;
the locking lever is provided with an elastic locking tab;
a corresponding locking profile is provided in the frontal region of the plug-in module and
the locking tab engages behind the locking profile if the lever pull is completely pivoted out, thus preventing the lever pull from pivoting.
2. The plug-in module according to claim 1, wherein a face plate comprises an angled, essentially level side part with a comer region that is designed as locking profile.
the locking lever comprises a detent for locking in place the completely pivoted-in lever pull and the locking tab is attached to the detent.
5. The plug-in module according to claim 4, wherein the detent activates a switch for the active/passive switching of the plug-in module once the plug-in module is completely inserted.
a face plate with recess which forms the detent edge and through which the detent projects.
8. The plug-in module according to claim 1, further comprising:
an activation element that operates jointly with the front stop edge of the module rack acts upon the locking tab, such that the lever pull is automatically unlocked during the insertion of the plug-in module.
9. The plug-in module according to claim 8, wherein the activation element is embodied as extension of the locking tab and rests with pre-tensioning against the lever arm of the lever pull.
a lever pull, including
a handle arm; and
a lever arm attached to the plug-in module for rotation from an inward position when the plug-in module is inserted in the module rack to an outward position when the plug-in module is removed from the module rack, said lever arm having a pressing shoulder and a tail skid, said tail skid engaging the front stop edge when the plug-in module is inserted in the module rack; and
a locking lever including
an activation arm rotatably attached to the handle arm of said lever pull;
a detent extending approximately perpendicular to said activation arm, said detent projecting through a recess in the face plate when the plug-in module is inserted in the module rack;
a locking tab extending from said detent approximately parallel to said lever pull, said locking tab engaging the locking profile when the plug-in module is removed from the module rack thereby preventing said lever pull from pivoting beyond said outward position; and
14. The plug-in module according to claim 13, wherein the locking tab is an elastic locking tab.
a lever pull including
a lever arm attached to the plug-in module for rotation from an inward position when the plug-in module is inserted in the module rack to an outward position when the plug-in module is removed from the module rack; and
an activation arm rotatably attached to the handle arm of said lever pull; and
a locking tab engaging the locking profile when the plug-in module is removed from the module rack thereby preventing said lever pull from pivoting beyond said outward position.
16. The plug-in module according to claim 15, wherein the locking tab is an elastic locking tab.
a detent extending approximately perpendicular to said activation arm, said detent projecting through a recess in the face plate when the plug-in module is inserted in the module rack.
18. The plug-in module according to claim 15, wherein said locking tab extends approximately parallel to said lever pull.
a pressing shoulder; and
a tail skid for engaging the front stop edge when the plug-in module is inserted in the module rack.
20. The plug-in module according to claim 19, further comprising:
This application claims the priority of European Patent Application No. 03 016 291.1, filed on Jul. 18, 2003, the subject matter of which is incorporated herein by reference.
The invention relates to a plug-in module for plugging in and/or pulling out of a rack having at least one front stop edge. The plug-in module comprises a lever pull that is positioned pivoting in the front region of the plug-in module and is provided with a handle arm and a lever arm.
Thus, it is the object of the present invention to create a plug-in module for which the lever pull in the completely pivoted-out position can be locked in place reliably with simple mechanical means, wherein it should be possible to release the locking easily and without problems during the insertion of the plug-in module into the rack.
In the following, an exemplary embodiment of the invention is explained with the aid of the enclosed Figures, which show in:
FIG. 3 A perspective representation of the locking lever shown in FIG. 1 a.
FIG. 4 A perspective representation of the lever pull shown in FIG. 1 a.
FIGS. 5 a and 5 b A perspective representation of the front corner region of the plug-in module shown in FIG. 1 a.
FIG. 6 a The lower end of the front panel for the plug-in module shown in FIG. 5 a, in a perspective representation from the inside.
FIGS. 1 a to 1 d clearly illustrate the operation of pulling a plug-in module 1 out of a module rack, wherein only the lower front stop edge 2 of the rack can be seen, which may take the form of a module rail and/or module bar.
FIG. 6 b shows the front panel 4 from the front, wherein the locking profile 21 is formed onto the lower end of side part 5 a. This locking profile projects over the front panel 4 toward the front. The end stop 30 that faces toward the inside can be seen at the rear edge of side part 5 a. The front panel 4 with side parts 5 a, 5 b and the locking profile 21, designed in this way, can be produced as one piece by stamping it out and bending the side parts 5 a, 5 b.
FIG. 7 a shows an alternative embodiment of the front panel 4. A corner piece 33 is attached with screw 34 to the front panel 4 in the lower region of front panel 4, wherein the corner piece 33 forms an extension of the side part 5 a.
The inside of front panel 4 according to FIG. 7 a is shown in FIG. 7 b. The front panel 4 is provided with a sheet metal holder 35 that is bent at a 90° angle toward the inside. The sheet metal holder 35 contains a bore 36 with collar 37 formed around it. The bore 36 is provided with an internal thread (not shown herein), into which the screw that holds the corner piece 33 is screwed. The corner piece 33 encircles the lever arm 8 of lever pull 6. The bearing bore 28 in the lever arm 8 is aligned with the bore 36 in the sheet metal holder 35. The corner piece 33 and the lever arm 8 are positioned at a distance to the sheet metal holder 35, such that the circuit board for the plug-in module can be inserted into the space between them. The circuit board is then also held in place by the screw that holds the corner piece 33.
The front panel 4 according to FIG. 7 a is shown by itself in FIG. 8 a, wherein the side part 5 a is shortened by the height of the sheet metal holder 35, thus offering space for holding the corner piece. The inside view is shown in FIG. 8 b, which shows that the sheet metal holder 35 projects perpendicular toward the inside and is aligned parallel to the side parts 5 a, 5 b.
FIGS. 9 a and 9 b show a perspective representation of the corner piece 33. A bore 38 is arranged on the longitudinal side of the corner piece 33. The bore 38 projects through a bushing 39 on the inside of corner piece 33. The bushing 39 serves to accommodate the lever pull that is guided inside a groove 40. A stopper 41 that limits the maximum angle of rotation of the lever pull is formed onto the front, upper edge of the corner piece 33.
