Description

The present invention relates to a housing arrangement according to the preamble of claim 1. The present invention also relates to an electrical series connection device, which can be lined up on a mounting rail, with such a housing arrangement. The present invention further relates to a method for locking the lower housing part to the upper housing part of the housing arrangement.

Housing components--in particular for accommodating electrical and/or electronic components--are often detachably connected to one another by latching. In this case, a latching hook arranged on a latching arm latches behind a latching edge of a recess. The locking arm is initially bent until the locking hook engages in the recess. With such a latching, there is play between the latching hook latched on the latching edge and the latching edge, which means that the housing components also have play in relation to one another.

A housing arrangement according to the preamble of claim 1 is from U.S. 2009/0075505 A1 known. Other housing assemblies with these features disclose the EP 0 913 891 A2 , the DE 10 2008 019 009 A1 and the U.S. 6,626,688 B1 .

The object of the invention is to fasten two housing components to one another in a detachable manner with virtually no play in a structurally simple manner.

The object is achieved with a housing arrangement according to claim 1, an electrical series connection device according to claim 7, and a method for clamping a housing top part on a housing bottom part of a housing arrangement without play according to claim 9. Advantageous embodiments can be found in the dependent claims.

According to the characterizing part of claim 1, the rolling surface lies in the same plane as a surface of the lower housing part, which rests against a surface of the upper housing part when the housing arrangement is assembled.

When the locking lever is pivoted, the contour thus rolls on a rolling surface of the lower housing part. The clamping means is not latched between the contour and the clamping surface but is locked in a clamping manner in the manner of claim 1 . In the locked or locked position, the clamping means is therefore arranged in the recess. The contour and the clamping surface encompass the clamping means on opposite sides and bear against it.

The upper part of the housing and the lower part of the housing are pulled toward one another when they are pivoted. Particularly preferably, the recess and the clamping means are arranged and dimensioned in such a way that the upper part of the housing and the lower part of the housing also bear against one another with as little play as possible in the locked position.

For this purpose, a clamping leg, on which the clamping surface is arranged, is preferably provided on the locking lever and has a simple structural design. The clamping leg is preferably arranged on a clamping arm, the length of which preferably corresponds to the width of the clamping means. For this purpose, the clamping means is preferably web-shaped or pin-shaped. In this embodiment, the upper part of the housing and the lower part of the housing are pulled together with a precise fit and are arranged on one another with as little play as possible in the locked position.

In a preferred embodiment, a locking means for locking the locking lever on the upper part of the housing is also arranged on the locking lever. The latching means is preferably latched in the released position in a first latching groove, and therefore in a first defined position, and in the latched position in a second latching groove, and therefore in a second defined position, in the upper part of the housing. As a result, the locking lever can be arranged in two defined positions. The first defined position of the locking lever, in which the latching means is arranged in the first latching groove and the locking lever is in the released position, allows the upper part of the housing to be pushed easily onto the lower part of the housing. The second defined position, in which the latching means is arranged in the second latching groove and the locking lever is in the locked position, ensures additional fastening security, so that the locking lever of the upper part of the housing does not unintentionally move out of the position exclusively locked on the lower part of the housing and not out as well the locked position.

It is particularly preferred that the housing arrangement has two locking levers which are arranged on opposite sides of the housing top part. In this embodiment, the upper part of the housing and the lower part of the housing are evenly pulled towards one another by pivoting the locking levers at the same time. It is also possible to press only the upper part of the housing onto the lower part of the housing, in which case the movement of the locking lever is initiated automatically. However, a housing arrangement is also preferred in which one end of the upper housing is partly attached to the lower housing part in a different way, for example latched or arranged pivotably on this, and the other end of the upper housing part has the locking lever for clamping the housing parts together according to the invention.

The object is also achieved with an electrical series connection device which can be lined up on a mounting rail and which has such a housing arrangement. The housing arrangement of this electrical series connection device is preferably provided for accommodating an electrical assembly. It is preferred that electrical connection means for electrical lines, in particular supply and/or signal lines, are provided on and/or in the upper part of the housing and/or on and/or in the lower part of the housing. The electrical assembly and/or electrical connection means arranged in the housing arrangement can be accessed very easily and quickly by detaching the upper part of the housing from the lower part of the housing.

The object is also achieved with a method for largely play-free clamping/locking of the upper housing part on the lower housing part of the housing arrangement according to the invention, the locking lever being arranged on the upper housing part in the released position, the upper housing part being pressed onto the lower housing part so that the locking lever moves in the pivoting direction is pivoted, the contour rolls on the rolling surface, and the clamping means is clamped in the recess.

The upper housing part and the lower housing part can therefore be fastened to one another simply by pressing the upper housing part onto the lower housing part. Starting from the released position, the contour is rolled along the rolling surface, so that the clamping means is clamped in the recess. The jamming can therefore be carried out very easily manually without further aids.

The object is also achieved with a method for releasing the upper housing part from the lower housing part of the housing arrangement according to the invention, wherein the locking lever is arranged in the locked position on the upper housing part, being pressed in a release direction so that it is pivoted against the pivoting direction, the contour rolls back on the rolling surface and the clamping means disengages from the recess. The loosening can therefore also be carried out very easily manually without further aids.

When assembling or retrofitting an electrical series connection device with the housing arrangement, no additional tool is therefore required to detach and clamp the housing components to one another.

The invention is explained in more detail below with reference to the drawings using exemplary embodiments, with further advantages of the invention becoming clear. Show it:

The housing arrangement 3 has a housing upper part 1 and a housing lower part 2 . 1 shows it in the locked position V, in which the upper housing part 1 is detachably attached to the lower housing part 2.

In the embodiment shown here, the housing arrangement 3 has a first end 31 and a second end 32 which are opposite to one another. A locking lever 11 is provided at both ends 31, 32, with which the housing components 1, 2 can be fastened to one another. For this purpose, the locking levers 11 can be pivoted in opposite pivoting directions 41 for clamping and releasing the housing components 1, 2 (preferably automatically when the housing component 1 is pressed open).

This makes handling very easy for an operator. One of the locking levers could also be replaced by an articulated pivot connection.

Handling is explained below using one of the locking levers 11 as an example. The locking lever 11 is arranged on the upper part 1 of the housing so that it can be pivoted reversibly about a pivot axis 4 . It is arranged in an interior space 10 of the upper part 1 of the housing. For this purpose, pins 110 are arranged in alignment with one another on opposite sides (not labeled) of the locking lever 11, which form the pivot shaft and are arranged concentrically around the pivot axis 4 in the assembled state of the locking lever 11 in the housing upper part 1. The pins 110 are each mounted in bores 42 in the upper part 1 of the housing.

By pivoting the locking lever 11 in a pivoting direction 41, the upper housing part 1 can be releasably locked on the lower housing part 2 from a released position L into a locked position V. In the released position L, the upper housing part 1 is released from the lower housing part 2 . Starting from the released position L, the upper housing part 1 can be arranged on the lower housing part 2 by sliding it on. In the locked position V, the lower housing part 2 is detachably fastened to the upper housing part 1 .

A recess 14 (see Fig. 2 (c), (d) and 3 (a), (b) ) intended. The recess 14 is secured by a clamping surface 141 (see Fig. 3 (b) ) and a contour 111 opposite the clamping surface 141. A clamping means 23 (see Fig. 1(b),(c) ) arranged.

The contour 11 is arranged eccentrically to the pivot axis 4 . It is arcuate, in particular round. This reduces its distance A from the clamping surface 141 (see Fig. 3 (a) ).

In the locked position V, in the 1(a)-(c) is shown, the clamping means 23 engages in the recess 14 of the locking lever 11 .

2 shows in (a) and (b) the detachment of the upper housing part 1 from the lower housing part 2. It shows the 2 (a) the jammed position that is assumed here. 2 B) shows the released position L.

Starting from the locked position V, the locking lever 11 is pushed in a release direction 62 . This is shown schematically by an arrow F2. In the process, the locking lever 11 is pivoted counter to the pivoting direction 41 .

The contour 111 arranged on the locking lever 11 thus rolls off on a rolling surface 21, which is arranged on the lower housing part 2 (see Fig. 3 (b) ). As a result, the clamping means 23 disengages from the recess 14 arranged in the locking lever 11. The housing arrangement 3 is then in the released position L. In the released position L, the upper housing part 1 can be removed from the lower housing part 2. This is shown here schematically by the gap S between the upper housing part 1 and the lower housing part 2 .

Starting from the released position L, the upper housing part 1 and the lower housing part 2 can be fastened to one another by pressing the upper housing part 1 onto the lower housing part 2 . It can be seen that for this purpose it is pressed in a clamping and locking direction 61 which extends transversely to the release direction 62 . This is indicated by an arrow F1 in the 2(c) shown schematically. In the process, the locking lever 11 is pivoted in the pivoting direction 4 . When the locking lever 11 is pivoted, the contour 111 rolls again on a rolling surface 21 of the lower housing part 2 .

Since the distance A between the contour 111 and the clamping surface 141 decreases, the clamping means 23 is clamped between the contour 111 and the clamping surface 141 . In contrast to latching, clamping of the housing components 1, 2 to one another is therefore used in this housing arrangement 3. This is what they show 3 (a) and 3 (b) .

In the locked position V the clamping means 23 is therefore arranged in the recess 14 of the locking lever 11 . The contour 111 and the clamping surface 141 enclose the clamping means 23 on opposite sides and bear against it.

When jamming, the upper housing part 1 and the lower housing part 2 are pulled together. So that these rest against one another largely free of play, a clamping leg 113 is provided on the locking lever 11, on which the clamping surface 141 is arranged. The clamping leg 113 is spaced from the contour 111 by being arranged on a clamping arm 112 . A length L of the clamping arm 112, which determines the distance A of the clamping surface 141 from the contour 111, corresponds to a width B of the clamping means 23. This is preferably designed in the form of a web or pin. As a result, in the locked position V, the clamping means 23 is arranged in the recess 14 largely free of play. Therefore, the upper housing part 1 and the lower housing part 2 in the locked position V are arranged without play on each other.

In order to enable the locking lever 11 to be positioned in a defined manner, at least one locking means 114 for locking the locking lever 11 in place on the housing upper part 1 is also arranged on the locking lever 11 . The locking means 114 is locked in the released position L in a first locking groove 13 of the housing upper part 1, and in the locked position V in a second locking groove 12 of the housing upper part 1. Since the latching means 114 is latched in the released position L in the first latching groove 13 and the locking lever 11 is therefore in a first defined position, the upper housing part 1 can be slid onto the lower housing part 2 very easily. The second defined position of the locking lever 11, in which the locking means 114 is arranged in the second locking groove 12 and the locking lever 11 is in the locked position V, ensures additional fastening security, so that the locking lever 11 does not unintentionally move out of the locked position V solves.

The clamping of the upper housing part 1 and the lower housing part 2 to one another is therefore possible very quickly and easily by pressing the upper housing part 1 onto the lower housing part 2 without an additional tool. In order to release the upper housing part 1 from the lower housing part 2, in the embodiment shown here with the two locking levers 11, only the two locking levers 11 have to be pressed in their release direction 62 (opposite to one another). This can also be done very quickly and easily without additional tools.

The embodiment of the housing arrangement 3 shown here is provided for an electrical series connection device. Such series connection devices can be lined up next to one another on a mounting rail 5 . For this purpose, the lower housing part 2 of each series connection device has fastening means (not designated) with which it can be fastened, in particular latched, to the mounting rail 5 . The lower housing part 2 and/or the upper housing part 1 are provided for accommodating one or more electrical assemblies (not shown). In addition, electrical connection means (not shown) for electrical lines (not shown) are provided on and/or in the housing components 1, 2. The electrical assemblies and/or connection means can be accessed very easily and quickly by detaching the upper housing part 1 from the lower housing part 2 .
