Problems solved by technology

[0005] Since this connecting measure is inserted into the mounting switchgear, the position of the connecting rivet cannot be freely selected; the riveted connection or connecting part can only be arranged in such a position, where the switchgear parts and structural components remain inside the housing as specified for them on the position
[0006] Since such a riveted connection cannot be provided in the region of the receiving space for the connecting clips, but because connecting measures are required there, and since the screw clips are often locked more strongly than necessary when connecting the conductor connections, possible occurrences , the two housing parts tend to bend in the area of ​​the connecting clips, whereby gaps at the splice line can form here, through which dirt can enter the housing

Embodiment Construction

[0020] The electrical installation device has two housing half-shells 10 , 11 which have a cup shape and which bear against each other with their exposed edges.

[0021] Such as figure 2 As shown, an internal view of a housing half-shell is shown, and the housing half-shell 10 includes: a wide face 12 with a T-shaped perimeter; a front face 13; two rear faces 14 and 15; two front narrow faces The faces 16 and 17 and the rear narrow faces 18 and 19 extend parallel to one another and perpendicularly to the front face 13 . Furthermore, the housing or housing half-shell 10 has a rear fastening surface 20 which has a recess 21 for snapping the mounting switching device onto a support rail, preferably a cap-shaped support rail. The front front wall 22 , the two rear front walls 23 and 24 and the rear side walls 25 and 26 are formed on the boundary edges of the wide face, which extend perpendicularly to the wide face 12 and thus form a half-shell. A corresponding expansion is also...

Abstract

The invention relates to an installation switch device with a housing of insulating material of a shell construction, with a front and a mounting side and a narrow and a broad side connecting the front and mounting sides, comprising a first and a second housing shell held together by connector means with formation of a joint line running parallel to the circumferential contour of the broad side of the housing. The connector means are exclusively clipping connectors.

Description

technical field [0001] The invention relates to an electrical installation switchgear according to the preamble of claim 1 It comprises: a housing of insulating material in the form of a shell structure, which has a front side (Frontseit) and a fixing side (Befestigungsseit) and narrow and wide sides connecting the front side and the fixing side; a first and a second housing shell, which are passed through The connecting means are fastened together forming a circumferential joining line, which runs parallel to the contour of the broad side of the housing. Background technique [0002] Such a mounting switchgear (for example a power switch) has a front face and two rear faces as well as fastening faces, wherein the front and fastening faces are connected to each other by front and rear narrow and wide faces. They consist of two housing shells, which are generally cup-shaped and accommodate the components of the circuit breaker in the cup-shaped interior. One of the two hou...
