The invention shown in an exploded view in FIG. 1 Connection device 10 has a trough-like lower part 12, the Attachment of the connection device 10 provided in an installed position is. The lower part 12 may, for example, in a wall box or be secured in a cable duct. The lower part 12 has a first Lower section 14 and a removable side wall section 16 on. The first lower portion 14 forms a forward and on a sidewall open trough. The side wall portion 16 is bilateral provided with sliding guides 18 and can by means of these sliding guides inserted into the first lower portion 14 of the lower part 12 become. At its in the illustration of FIG. 1 rear end the side wall portion 16 is provided with a locking lug 20, the at a tongue extending in the insertion direction is arranged. These Latch 20 engages in the fully inserted state of the side wall portion 16 in a matching recess on the first base section 14 of the lower part 12 and secures the side wall portion 16 thereby on the first lower portion 14. On both sides of the locking lugs 20, the side wall portion 16 is arcuate to the lateral Sliding guides 18 out. Between these, to the latch 20 adjacent areas and the opposite floor areas of the lower portion 14 are in the fully inserted state of the side wall portion 16 then two adjacent cable feedthrough openings created for connection cable.

The first lower section 14 can thus be independent of the position of the Connection cable to be fixed in its intended installation position, For example, in a cable channel, then the connection cables led into the interior of the first lower portion 14 are and after insertion of the side wall portion 16 run the Connecting cable then through the corresponding cable passages. The assembly of the lower part 12 is thereby considerably simplified, because the base 12 is not prior to mounting in the installed position must be threaded on connecting cable. At the first lower section 14, the connection cables can then by means of a strain relief clamp 22 are secured and a braided shield of the connection cable can be contacted by means of a Schirmkontaktierungsschelle 24 become. The lower part 12 is advantageously made of zinc die-cast or any other electrically conductive material to provide a reliable To ensure shielding. The removable sidewall section 16 is also referred to as a carrying handle insert.

The connection device 12 furthermore has a connector module 26, the total of four terminals 28, two sockets 30, one Circuit board 32 and a Lötpinabdeckung 34 has. The terminals 28 and the sockets 30 are on a front side of Printed circuit board 32 arranged in the installed state of the connector module 26 from a front of the terminal, in the illustration Fig. 1 from bottom left front, is accessible. The terminals 28 and the sockets 30 are interconnected by interconnects connected, which extend on a back side of the circuit board 32. Soldering pins between the conductors and terminals 28 and the Sockets 30 are covered by Lötpinabdeckung 34. The Lötpinabdeckung 34 is latched onto the circuit board 32. The Solder pin cover 34 is provided for this purpose with two locking lugs 36 which each other opposite and each have a side edge of the circuit board 30 can snap. The solder pin cover forms a section wise around an outer edge of the circuit board 32 encircling Frame, wherein in the region of the terminals 28 between a Side edge of the circuit board 32 and the outer circumference of Lötpinabdeckung 34 each have a cable passage opening 38 is formed. In the Representation of FIG. 1 are only three cable passage openings 38th but in total there are four cable passage openings 38 provided in accordance with the four terminals 28. By means of Cable passage openings 38, the connection cables or cable wires the connection cable around the side edge of the circuit board 32 around and led to the respective terminals 28. The cable wires be after placing in the cable passage openings 38 held in the region of the associated terminals 28, without that a fitter must hold her. To make the cable wires easier Way to introduce in the cable passage openings 38, which is slotted outer edge of the cable openings and formed resiliently in the region of the slot. This is based on the Fig. 6 explained in detail.

After attaching the connection cable to the lower part 12 are thus the Cable cores through the corresponding cable passage openings 38 threaded and then the complete connector module 26 locked on the lower part 12. For this purpose, there are two at the Lötpinabdeckung more opposite locking lugs 40 provided in the appropriate Recesses on the lower part 12 can engage. In the presentation of the Fig. 1 is only one of the locking lugs 40 can be seen. The lower part 12 and the Lötpinabdeckung 34 are formed so that the connector module 26 in four different rotational positions on the lower part 12th can be locked. This will be explained in detail below. The latched in the lower part 12 locking lugs 40 can thereby from the open front side of the lower part 12 ago solved by, for example a screwdriver blade between an inner wall of the lower part 12 and a well-recognizable in Fig. 4 run-on slope the locking lug 40 is inserted. The connector module 26 can thereby also with built-in base 12 from the front into this be installed and removed, for example, to its rotational position for Lower part to change.

After locking the connector module 26 on the lower part 12 can the cable wires are inserted into the terminals 28. It should be noted that the lower part 12 already in its installed position is attached and thus latched to the lower part 12 Connector module 26 is secured in position and not held must become. A fitter has thus both hands free to the cable wires in the appropriate terminals 28 insert.

The terminals 28 are formed as self-tapping clamps and for pressing the cable wires into the terminals 28 can a standardized tool can be used. These standardized However, tools require right and left of the terminals 28 comparatively much space. To make room for such an assembly tool To create, the first lower portion 14 is in the range of all his four corners with through holes 42 provided. These passages 42 interrupt the circumferential side wall of the first Bottom section 14 and allow the cable cores in particularly simple way with a standardized assembly tool can be pressed into the terminals 28. This Eindrückvorgang the cable wires takes place in a state in which the connector module 26 already in its installed position in the lower part 12 is attached.

The passage openings 42 are closed by means of a cover 44, the at its four corners to the through holes 42nd suitable and in the assembled state these occlusive projections 46th having. Also, the lid 44 is like the lower part 12 of electrical Conductive material, such as zinc die casting, making a reliable Shielding of the connection device 10 is ensured.

The cover 44 can by means of two fastening screws 48 on the first Lower section 14 are attached. It should be noted that too the lid 44 is fixed in four different positions on the lower part 12 can be to adapt to the different possible mounting positions the connector module 26 to be adjusted. The first base section 14 has four for screwing the mounting screws Dome 50 on, which are each provided with a threaded hole and of which only two can be seen in the illustration of FIG. Depending on the installation position of the connector module 26 are two opposite Dome 50 used to fix the fixing screws 48 screw. After placing the cover 44 is the circuit board 32 between the first lower portion 14 and the lid 44th arranged and the circuit board 32 is located specifically on an upper side of the Dome 50 on. After tightening the mounting screws 48 is the connector module 26 thereby very reliable on the lower part 12th attached.

On the cover 44 can still be placed a central plate 52, which, for example, carries a description of the available connections and, for example, color coordinated with a surrounding cable channel is.

In the illustration of FIG. 2, the lower part 12 is shown enlarged. Above the dome 50 in the first lower portion 14 is one each approximately square recess 54 in the circumferential side wall of the Bottom parts 12 arranged. In the area where the side wall of the Lower part 12 is formed by the removable side wall portion 16, is the recess 54 in this removable side wall portion 16 arranged. The recesses 54, the locking lugs 40th record the Lötpinabdeckung 34, wherein the two locking lugs 40 at opposite sides of Lötpinabdeckung 34 are arranged. The Lötpinabdeckung 34 and thus the complete connector module 26 can thus on the lower part 12 by means of the locking lugs 40 which in each case a recess 54 engage, in four different rotational positions be mounted on the lower part 12, namely in that shown in FIG Starting position and at 90 °, 180 ° and 270 ° to this starting position twisted. The connector module 26 is thereby an in 2 indicated center axis 56 of the lower part 12 is rotated.

The side wall portion 16 can also with built-in base 12th be solved by this, for example, only after the wall installation of the lower part 12 to introduce connection cable in the lower part 12. For this example, a screwdriver blade between the Dom 50 and the side wall portion 16 introduced. This will be the Tongue with the locking lug 20 of the side wall portion to the outside, from Lower part 12 away, bent and the side wall portion 16 can be pull out of the lower part 12.

The illustration of Fig. 3 shows the lower part 12 in a view of diagonally behind. It can be clearly seen from the representation of FIG. as the locking lug 20 of the removable side wall portion 16th snaps behind a bottom of the first base portion 14 when the side wall portion 16 is completely in the first lower portion 14 has reached the inserted position. As with reference to FIG. 1 to was recognized, the latch 20 is doing at the front end of a tongue and thus slightly resiliently arranged on the side wall portion 16. Of the Bottom of the first lower portion 14 has in the region of the latch 20 a slight depression 58 on. This recess 58 facilitates that Attaching a tool, such as a screwdriver, to push the locking lug 20 to the outside, so that the side wall portion 16 can be removed from the first lower section 14.

Well visible in the illustration of FIG. 3 are also the passage openings 42 on the first lower portion 14, which extends up to a extend front edge of the base portion 14 and with which, as mentioned, space for pushing on a mounting tool is created on the terminals 28.

In the illustration of FIG. 4, the connector module 26 is in a view shown enlarged obliquely from the front. In the view of FIG. 4 is specifically the formation of the detents 40 and 36 on the Lötpinabdeckung 34 to recognize. As mentioned, the locking lugs 40 in the Snap through openings 54 of the lower part 12. As in FIG. 4 to recognize the locking lugs 40 when inserting the Lötpinabdeckung 34 in the lower part 12 to the inside, towards each other, pressed, until they reach the recesses 54 and then back out, away from each other, move. For this purpose, the locking lugs 40 are resilient arranged on the Lötpinabdeckung 34, for example made of plastic consists. The locking lugs 40 hold the connector module 26 thus in the installed position on the lower part 12 and secure the connector module 26 against pulling against the insertion direction. To remove the connector module 26 again from the lower part 12, can the locking lugs 40 either from an outside of the base 12 ago pushed through the through holes 54 inwards or, as already described, from the front of the base 12, for example by means of a screwdriver, disengaged become.

By contrast, the locking lugs 36 secure the printed circuit board 32 to the solder pin cover 34. The circuit board 32 is for this purpose on the Lötpinabdeckung 34 pushed, it presses the locking lugs 36 apart until this snapping back over the PCB 32 and thereby secure.

In the illustration of Fig. 5, the connector module of oblique shown at the back. In this view are the cable passages 38 well recognized, which are intended to the individual cable wires the terminals around the side edge of the circuit board 32nd around on its front to the terminals 28 to lead. To the cable cores when threading as well as later in the installed state not to damage, is each of the cable passages 38 provided with a guide slope 60 which from a bottom of the Lötpinabdeckung 34 obliquely outward to the side edge of the circuit board 32 leads.

Furthermore, the Lötpinabdeckung 34 is on the chamfers 60 in Essentially opposite side of the cable passage openings 38 provided with Kabelleitflächen 62, from the cable passages 38 lead diagonally outside. Through these Kabelleitflächen 62nd in conjunction with the bevels 60, the cable cores are in the direction led to the terminals 28. This will be the one sharp creases, which always carries the risk of damage to the cable wires prevent, and second, the cable cores to the passage through the cable passage openings 38 already approximate held in a position in which they then into the terminals 28 can be inserted.

In Fig. 6, the connector module 26 of FIG. 1 in sections and enlarged. You can see one of the terminals 28, which is arranged on the printed circuit board 32. To recognize further are the outer locking lugs 40 for securing the connector module 26 on the lower part 12 and the inner locking lugs 36, with which the solder pin cover 34 is latched to the circuit board 32 becomes. The solder pin cover 34 defines together with a portion the side edge of the circuit board 32, directly to the terminal 28 adjacent, the cable passage opening 38. The outside and by the Lötpinabdeckung 34 formed edge of the cable passage opening 38 consists of two Berandungsabschnitten 70, 72, each integral with the Lötpinabdeckung 34, for example made of plastic injection molding. The two boundary sections 72, 70 are separated by a slot 74. The slot 74 serves to insert the cable wires into the cable passage opening 38. By providing the slot, the cable cores must thereby not be threaded into the cable passage opening 38, but can be pulled through the slot 74 in a particularly simple manner and placed in the cable passage opening 38. The boundary portions 70, 72 or at least the boundary portion 72 is resilient and / or resilient on the Lötpinabdeckung 34 arranged so that the width of the slot 74 is smaller can be as the diameter of the cable cores to be inserted or Electric wire. The width of the slot 74 may also be zero, so that the boundary portion 72 on an inwardly directed boundary surface the boundary portion 70 rests. For inserting a cable core or a cable, the boundary portion 72 then becomes a piece pressed far inward until the cable core or cable through the Slot 74 can be inserted into the cable passage opening 38. After the cable core or the cable in the cable passage opening 38 are placed, the edge portion 72 then snaps back in its rest on the boundary portion 70 position.

In Fig. 6 it can be further seen that the cable passage opening 38 facing inner surfaces of the boundary portions 70, 72 as Cable cores are formed to in the cable passage opening 38th arranged cable cores at least approximately in the region of the terminal 28 to hold. This has a fitter after insertion the cable wires or a cable in the cable passage opening 38 both hands free to the individual cable wires in the individual Slots of the terminal 28 to lay and then a standard tool for pressing the cable wires into the terminal 28 and to simultaneously cut off the cable cores.

In the illustration of FIG. 7 is a lower part 76 according to another Embodiment of the invention shown. The lower part 76 differentiates itself from the lower part 12 shown in FIG. 1 only by the configuration of a removable side wall section 78. Reliably around the sidewall portion 78 at a first base portion of the base 76 is the side wall portion 78 provided with a U-shaped attachment 80 having a through hole forms and the dome 50 of the first lower portion 79 engages around. The Dom 50 is in the installation position of the removable shown in Fig. 7 Side wall portion 78 characterized between the U-shaped Projection 80 and the rest, plate-shaped portion of the Sidewall portion 78 added. The side wall portion 78 is not only via lateral sliding guides 82 on the first lower section 79 secured, but also about the intervention of the cathedral 50. Since the side wall portion 78 in the, the U-shaped projection 80 right and left adjacent areas a boundary of a Cable passage opening forms, this is very advantageous because not too it is feared that the side wall portion 78 by handling in the lower part 76 inserted cables from the first lower part portion 79th solves.

The illustration of FIG. 8 shows the side wall section 78 in an enlarged, perspective view. Good to see are the side guides 82, each one opening outwards and sideways Define groove. A in Fig. 8 overhead boundary surface of Side guides 82 is at an angle of more than 90 ° to Grooved base arranged so that an expanding towards the outside Cross-sectional shape of the groove of the side guides 82 results. Such Cross-sectional shape facilitates the insertion of the side wall portion 78th in the first lower portion 79 in the already installed state. In addition, the groove bottom of the side guides 82 may be formed be that a distance of the groove bottoms of the opposite side guides 82 at the front end of the side wall portion 78 something is less than at the rear end of the side guides 82 of the side wall portion 78. This also allows the side wall portion 78th more easily insert into the first lower section 79.

Furthermore, in FIG. 8, the arrangement of the U-shaped projection 80th to recognize on the side wall portion 78. A boundary of the Through opening for the dome 50 on the side wall portion 78 is thereby formed on three sides by the U-shaped projection 80.
