The lower part of the housing 12 has a high housing end wall 14 and one opposite low housing end wall 16. The lower housing part 12 has a trough-like shape, but with the side walls starting from the low end wall 16 rise to the high end wall 14. Either the end walls 14, 16 and the side walls of the lower housing part stand vertically on a rear wall of the housing, which is shown in FIG. 1 is not recognizable.
A mounting plate 18 is parallel within the lower housing part 12 arranged and fastened to the rear wall of the housing, for example by Screws connected to the rear wall of the housing. On the mounting plate 18 are two RJ45 sockets at an angle of 45 ° to the mounting plate 20 arranged side by side. On the mounting plate 18 are also self-tapping terminal strips 22, wherein one terminal block 22 is assigned to one of the sockets 20. In the illustration in FIG. 1, only one terminal strip 22 can be seen. The terminal strips 22 and the contacts of the sockets 20 are connected to each other via conductor tracks on the as a printed circuit board trained mounting plate 18 are arranged. Still located on the mounting plate 18 train protection clamps 24 for train protection inserted connection cable.
As can be seen in Fig. 1, connection cables can be standardized Seal fittings 26 are inserted into the interior of the housing. The Seals 26 are on an outside of the low housing end wall 16 arranged so that a connecting cable 28 through the sealing screw connections 26, through an aligned opening in the lower housing end wall 16, to the train protection clamps 24 and extends to a terminal 22. Sealing fittings or bores that are not used and are closed with blind plugs thereby in all end walls, side walls and in the bottom of the housing be arranged. The sealing fittings can also be used as train protection be suitable for inserted connection cables. The train protection clamps 24 can for example also for the electrical connection a cable shield with a shielding device of the sockets 20 be provided.
In each of the sockets 20 in the illustration of FIG. 1 is a RJ45 plug 28 with connected connection cable 30 inserted. As can be seen in FIG. 1, the connecting cables 30 are connected the high housing end wall 14 into the interior of the lower housing part 12 guided and lie on an upper edge of the high housing end wall 14 on. Are in the area of the support on the high housing end wall 14 the connection cable 30 with a train protection clamp 32 on the lower housing part attached. 1 clearly shows that the introduction of the connection cable 30 over the high housing front wall 14 and the inclined arrangement of the sockets 20 a The connection cable 30 can be guided with large bending radii.
A division level between the lower housing part 12 and that in the Fig. 1 housing cover, not shown, is replaced by the one in FIG upper edge of the high housing end wall 14, the two side walls and the low housing end wall 16 are formed. It can be seen that such a division level in sections in is inclined at a first angle to the rear wall of the housing. The Sockets 20 on the mounting plate 18 inside the lower housing part 12 are inclined by a first angle which is rectified is to the first angle through which the parting plane to the rear wall is inclined. This special and advantageous training of As already mentioned, lower housing part 12 allows guidance the connection cable 30 with large bending radii and also ensures for easy access to the interior of the lower housing part 12. Special are the terminal strips 22 that are adjacent to the low housing end wall 16 lying, easily accessible, which is especially important when inserting of the individual wires of a cable to be connected into the self-tapping Terminal strips 22 is of great importance. On the other Side, the high housing end wall 14 ensures that the mounting plate 18 with all components arranged on it within the interior defined by the division level and the lower housing part can be arranged. This means that they are all inside the lower part of the housing 12 arranged components also against lateral Pedal and impact loads protected, even when a Housing cover has not yet been installed or has already been knocked off.
On the rear wall of the housing is the lower housing part 12 with locking means 34 provided, which are snapped into a sheet metal rail 36. A more detailed one Explanation of the locking means 34 and the sheet metal rail 36 is made 4 and 5.

The housing cover 38 is attached to the by means of two fastening screws 40 Lower housing part 12 fixed. The housing cover 38 is in the Fig. 2 not recognizable, circumferential seal provided in assembled state on the end edges of the side walls and the end walls 14, 16 of the lower housing part 12 rests and thereby the interior of the lower housing part reliably seals, so that the protective housing overall a splash-proof accommodation of a Allows plug connection. The circumferential seal is also beyond on the top of the connection cable 30 so that the insertion point this connection cable is reliably sealed. The Housing cover 38 is also provided with a display field 42. 2 that is relative to the rear wall of the housing sloping parting plane between lower housing part 12 and Housing cover 38. In the area of the high housing end wall 14 is a through hole closed with a plug 39 arranged. In the through hole, a sealing screw for a Connection cables are arranged.
3, the mounting plate 18 is removed from the housing State shown. The mounting plate 18 is screwed through mounting holes arranged in the area of their corners with the Lower housing part 12 firmly connected. On the mounting plate 18 are the two sockets 20 arranged so that an insertion direction in the sockets 20 is at an angle to the mounting plate 18. This Angle is between 40 ° and 50 °, but can also for example are between 20 ° and 80 °. On opposite side edges of the Mounting plate 18 is a self-tapping connector 22 provided. On another side edge of the mounting plate 18, the connects the side edges with the terminal strips 22 and the mating face facing away from the sockets 20, the two train protection clamps 24 arranged. Further train protection clamps indicated by dashed lines can on the, the train protection clamps 24 opposite Side edge must be arranged so that connection cable can be inserted over both side edges. As in Fig. 3 too can be seen is the mounting plate 18 for attachment and contacting provided by two connection cables, each with its own Train securing clamp 24 is provided. As already mentioned, serve the train protection clamps 24 also for contacting a cable shield.
The mounting plate 18 is designed as a printed circuit board, with conductor tracks on the rear side of the mounting plate, which is not visible in FIG. 3 18 run and consequently only indicated in dashed lines in some cases are.
The conductor tracks run from each terminal strip 22 to a respective one assigned socket 20 and the strain relief clamps 24 to a respective, assigned socket 20. The socket 20 and the terminal strips 22 and possibly the train protection clamps 24 are with connection pins in plated-through holes the mounting plate 18 soldered. All electrical components the junction box 10 are thus combined on the mounting plate 18, which forms a preassembled module.

Two latching hooks are arranged opposite each other and can accommodate the metal rail 36 between them. Like in the 5 can be seen, the sheet metal rail 36 has a U-shaped Cross section on, with the end regions of the opposite legs are each bent at right angles to the outside and thereby each form a mounting flange that extends over the entire length of the Sheet metal rail 36 extends. The sheet metal rail 36 is also called a top-hat rail referred to and is a standardized fastener in numerous Find junction boxes. On these two opposite mounting flanges are the locking hook 44 and thereby secure it Lower housing part 12 on the sheet metal rail 36. The sheet metal rail 36 has an elongated hole at each of its two opposite ends, through which a hole in the lower part 12 of the protective housing is accessible is. This allows special, possibly standardized further locking elements be attached to the DIN rail and the protective housing.
It can be seen in the side view of FIG. 5 that the latching hooks 44 from the rear wall 42 and arranged perpendicular to this Have arms on the side facing away from the rear wall 42 of the housing End locking lugs are arranged. The latches of opposing locking hooks 44 face each other, so that the mounting flanges of the sheet metal rail 36 behind the locking lugs of Can engage latch hook 44. On their, facing away from the rear wall 42 The fastening flanges of the sheet metal rail 36 lie on the side thus on the side of the locking lugs facing the housing rear wall 42 the locking hook 44. On their, the rear wall 42 facing Side are the mounting flanges of the sheet metal rail 36 each on a stop 46 formed on the protective housing. The Stops 46 are through the shoulders of one of the rear walls of the housing 42 outgoing projection formed. The protrusion has a cross-sectional shape which is attached to the rear wall of the housing Rectangle and a trapezoid that can be described with its longer Base side on the side facing away from the rear wall 42 of the housing of the rectangle is placed symmetrically. The section of the tab with a trapezoidal cross section forms a stop for the Base of the sheet metal rail 36, which connects the two legs. By the special chosen shape of the projection with the stops 46, the locking hook 44 and the sheet metal rail 36 can hold the Sheet metal rail 36 on the protective housing with easy insertion or snap fit can be achieved. The protrusions 48 are each only formed adjacent to the side walls of the lower housing part 12 and undercut so that within the protrusions one in FIG only indicated nut 50 can be arranged.
