It should first be mentioned that in the figures of the drawings only those parts of the electrical installation device are shown that are necessary for the explanation of the invention have meaning. For example, the leads to the installation device are simplicity omitted for the sake of clarity, "it should also be said that the missing parts can not only have a structure known per se, but also have a known structure Way can be assembled.

The terminal contact 20 shown in Fig. 1 has a iiittelsteg 21, from which four arms 22-25 are angled are, the arms 22, 23 as well as 24 and 25 are angled in the same pitch. The pair of arms 22, 23 is used to Receipt of a mating contact while the pair of arms 24 holds a connection point 26 for supply lines. The free ends are used to facilitate the introduction and retention of a mating contact in the pair of arms 22, 23 of the arms 22, 23 bent after the central web 21, so that the mating contact in the arm pair 22, 23 always with a spring force is held. to facilitate the bending of the free ends is located in the arms 22, 23, respectively a recess 27 so that the bending point is arranged in the region of this recess. Let it be further notes that the free ends of the arms 22, 23 have sideways recesses or bevels 28, so with an insertion into a housing, to be described later, does not impede the ends of the arms of the insertion oppose.

In Fig. 1 _e di junction 26 is formed as a second terminal 29. It has a central part 30 to which two legs 31, 32 are flanged. The two legs 31,

509817/0569

are slotted in the middle, so that two resilient lobes are created. The tabs on the leg 31 lie against the Arm 24, while the lobes of the leg 32 are angled so that they partially the spring action of the Tabs 31 can support if feed lines are arranged between the tabs and the arm 24. The two lobes of the leg 31 have tongues in some areas at their end. These tongues 33 protrude into an opening 34 of the arm 24 into it. The opening 34 is rectangular in plan view Shape. The part of the end that does not have the tongues 33 the flap rests against the arm 24. In the arm 24 are parallel to the two long sides of the rectangular opening 34 Grooves 35 are arranged, which are used to hold supply lines in areas.

A tab 36 is bent up from the central web 21, which, as before is described, is used to attach the terminal contact 20 in a housing.

The arm 25 of the connection contact 20 carries recesses 37, dfe can be used to fasten the foreign terminal 29, for example 37 soldered connections can be in these recesses for fastening the foreign terminal 29 on the arm 25 of the connection contact 20 be arranged. It should also be mentioned here that the foreign clamp 29 can also be fastened in that it is resilient between the arms 24, 25 of the terminal contact 20 is supported, a pull-out is avoided in that the tongues 33 of the Foreign clamp 29 protrude into opening 34 of arm 24.

In Fig. 2 a blank of the connection contact 20 according to FIG. 1 is shown. As can be seen from the figure, has the blank has a cruciform shape. Not yet described in this exemplary embodiment are four cut-outs

Β09817 / 05Θ9

stanchions 38, the bending of the arms during manufacture the connection contacts are intended to make it much easier, since this results in a bending edge when the arms 22 25 are angled is given. The connection contact is made as follows: First, the blank is like shown in Fig. 2 by punching, then the free ends of the arms 22 and 23 are bent over, the The bending edge lies in the area equal to the recesses 27. Finally, the two arms are in the area of the cutouts 38 angled approximately parallel to one another, the two arms pointing in approximately the same direction. To the Finally, the arms 24 and 25 are also angled parallel to one another, the recess 38 forming the angle relieved in this area. When the terminal contact 20 is finished, the arms 24 and 25 then point in opposite directions Direction of arms 22, 23.

In Fig. 3 you can see from the side view of the terminal According to Fig. 1, the assignment of the grooves 35 which, as already said, partially accommodate supply lines. The foreign clamp is not shown in this figure for the sake of clarity.

The embodiment shown in Figures 4-5 a connection contact has the following two differences in contrast to the first exemplary embodiment on. First of all, the connection contact has no foreign clergy, but on the arm 25 of the connection contact 2O an extension approach 39 is arranged, which at its free Has a slot 40 at the end, as well as tongues 41 resting against the slot. The second is the fastening in a housing to be described later via tabs 42 bent out of the plane of the arms 22, 23.

509817/056 9

The connection point 26, which is again designed here as a screwless connection terminal, is as follows manufactured: The extension extension 39 is angled so that after angling of the arms 24, 25 from the central web 21 the tongues 41 of the extension lug 39 in the opening 34 of the arm 24 come to rest. The production of the pair of arms 22, 23 receiving the mating contact takes place as in the first exemplary embodiment described. However, it should be noted here that the arms 22, 23 are not exactly parallel to one another from the central web are bent, but are angled slightly inclined to each other.

Bine supply line is as follows through the screwless Terminal connected according to the two exemplary embodiments of FIGS. 1-6. The leads are in the Grooves 35 inserted, removing the legs 31 or the extension attachment 39 from the arm 24. After this the leads abut the central web 21, they are through a cutting edge 43, which is located at the free end of the Extension approach 39 or on the leg 31 'is located, secured against being pulled out. To remove the leads from the screwless terminal, a Pressure is exerted on the tongues 33, as a result of which the legs 31 or the extension attachment 39 with its cutting edge 43 no longer rests on the supply line, so that the supply lines can then be removed. Through the slot 40 at the extension approach 39 or the two legs 31, two feed lines, which have different diameters in cross-section, can be used independently of one another attached by the connector. In the embodiment shown in FIGS. 7 and 8 a connection contact is the connection point 26 as

S0-9 817 / 0S69

Formed screw connection. For this reason, the connection point 26 only needs one arm for mounting, so that, as can be seen from Fig. 7, the blank of the terminal contact 20 has a T-shaped shape. The arm 24 is now not provided with a rectangular opening but with a round opening 44 through the one screw 45 is passed through. A counter plate 46 is designed as a nut for the screw 45. In the The free space 47 formed by arm 2 4 and counter plate 46, the feed lines can be inserted and fastened flocks. To prevent it from tightening or loosening the screw 45, the counter plate 46 rotates, the counter plate has a flattened portion on one of its faces, which abuts against the central web 21. This becomes a possible rotation of the counter-plate 46 avoided, while the up and down movement of the counter-plate is not hindered will. It should be mentioned here that either the arm 24 or the counter plate 46 has grooves for partial reception of supply lines may have. The rest of the formation of the terminal contact 20 is similar to that in previous embodiments.

In Fig. 9 and 10, a housing 48 of the terminal contact 20 is shown. The housing 48 has a cuboid shape and is in one piece. Inside the housing is a receptacle 49 which is used to hold the connection contact serves. The connection contact 20 is introduced into the receptacle 49 through an insertion opening 50. When inserting of the connection contact 20 into the receptacle 49, the tab 36 is pushed back through an inside of the receptacle 49. As soon as the connection contact with its arms 24,

is, against the end face 51 of the receptacle 49 springs the tab in an opening 52 so that the connector does not come off the receptacle 49 can be pulled out.

In the end face 51 of the receptacle 49 open bores 53, the

B09817 / Ö56 9

for introducing the leads into the connection point 26 to serve. The opening 34 on the arm 24 lies below a further opening 54, the opening being funnel-like enlarged towards the outside of the housing. The funnel-like enlargement 55 is used for easier operation an unlocking device 56, which was inserted into the opening and protrudes into the opening 34 in some areas. The unlocker 56 has the task of being released of the leads, the tongues 33 and thus the cutting edge 43 of to remove the supply lines so that they can then be removed from the connection point 26. To the bracket of the Sntsperrers 56 in the opening 54, a resilient projection or a locking lug 57 is provided, which is after Introducing the unlocker comes to rest in the opening on the inner wall of the receptacle 49.

If tabs 42 are provided on connection contact 20 instead of tabs 36, there is another opening in housing 48 arranged, in which the tabs snap resiliently and thus then prevent removal of the connection contact.

The insertion opening 50 is from three sides by one raised wall 58 enclosed. The importance of the fourth missing wall will be explained later, In FIG. 11 there is a housing 59 for the connection contact 20 shown, in which at the insertion opening 50 the raised walls SC elections. Otherwise the case is similar to the Cleia embodiment of FIGS. 9 and 13. In Fig. 11 two center lines a un-1 b of the end face of the housing are drawn. oie cinema opening 50 is now with the outlet contact 20 barometric to the middle - line a arranged, on the other hand asymmetrical to the center line b.

"sxo Hedeutuii'j such an order becomes" ig. 12 -: - visibly. In this figure, three housings 59 thread connection contact 20 are folded together by means of a thread to a socket module. The middle housing, however, is rotated about a longitudinal axis of the housing in such a way that the three "inlet openings 50 are no longer arranged on a line, but rather the middle" inlet opening is closer to the lower edge of the housing 59 than the other two. This arrangement gives a one-to-one assignment of the connection contacts to the mating contacts to be introduced for the socket outlet.

In Fig. 13, the middle housing is _r 59 arranged above in relation to the two lateral housings in which the introduced Gegeilkontakte are formed such that the middle contact first occurs in electrically leitfälliger connection with the mating connector. The three housings 59 are in turn held together by the frame 60. In FIG. 14, three housings according to the exemplary embodiment in FIGS. 9 and 10 are combined to form a structural unit. Ί ± β can be seen, each of these housings 43 lacks the high gasified -> 7and 58 on the lower side. The mating connector is now designed in such a way that it only carries a raised wall on the underside. This in turn makes the assignment of socket and mating connector unambiguous.

As already mentioned, the embodiments shown are only example implementations of the invention and this is not limited to it, rather are still various designs and applications possible. For example, in the embodiment according to FIG

also on the fourth side of the front of the housing be arranged a raised wall. However, this should then have a smaller wall thickness than that the remaining three walls, so that the mating connector with a wall that also has a smaller wall thickness, there is space in the missing space at the first wall, as well as a one-to-one assignment of the socket unit to the mating connector can be reached. The opening 54 could also be used to actuate the screw 45 can be used if the connection contact 20 is equipped with a screw fastening.

It should also be said that the terminal contact 20 also can be used in a housing in which several connection contacts can be built. For example a housing have three receptacles 49 into which the connection contacts 20 can then be inserted. Man would then already receive a socket with a housing.
