Connection terminal

The innovation relates to a connector comprising an in an insulating housing arranged clamping body, in the at least two electrical conductors can be introduced preferably from opposite sides are, of which one preferably has a blade terminal.

Terminals with a clamping body, in which at least two electrical conductors can be introduced, are well known. Included the connection between the clamping body and the electrical conductor can be made in the form of screwless terminals by between a Spring element and an associated surface of the clamping body, the electrical conductor is introduced and pressed against it. To with To hold a single spring element that can be introduced into the clamping body from different sides, the latter is preferably S-shaped educated. Such a screwless attachment is not specific to certain electrical conductor connections aligned so that in particular when using flat plugs there is a risk of unintentional slipping or loosening from the clamping body he follows.

However, it is often necessary that one terminal two must accommodate electrical conductor ends, one of which has a flat plug. Such a connection between a normal electrical conductor end and a flat plug is given, for example, for the supply of fluorescent tubes on the ballast side Include flat connectors.

The task of the present innovation is to connect a connection clamp to the to be designed in such a way that two electrical conductors are electrically connected to one another by these, wherein it should be ensured that a firm connection and secure guidance is also given for an electrical conductor, the one

Has flat plug, so that in particular a problem-free and a

safe use in electrical devices is given, for example

\ J have a flat plug on the device side.

The object is achieved according to the invention in that the clamping body comprises a U-shaped base body, the free parallel or almost parallel legs of which guide surfaces for the electrical conductors to be introduced, of which one (first) guide surface with one facing the other (second) Guide surface movable spring element cooperates and the second

Guide surface for its part by bent, parallel edge areas of the corresponding (second) leg is limited, the bent edge regions at least partially in the direction the second guide surface extend. In other words, a connector is proposed according to the innovation, which as an integral Has components a screwless terminal and a receptacle. This ensures that a secure electrical connection between there is a stripped electrical conductor end and an electrical connection with a flat plug. So you don't run There is a risk that, in particular, the flat plug can slide out of the associated holding device in the clamping body in an uncontrolled manner, since that is taken up in the usual way by a flat receptacle.

To ensure safe electrical contact between the flat plug and to produce the associated flat receptacle, the extend free edges of the bent edge areas of the second leg in

Direction of the second guide surface and are at least sharp-edged, so they form so-called scratching edges, so that any oxidation layers or paint protection layers formed on the flat connector can be removed. The cooperating with the first guide surface spring element, that the screwless clamp forming part of the terminal is preferably of the second guide face opposite surface of the same leg of J or extends therealong. The second

Legs have a tab which is inserted into a recess in the spring element intervenes. The spring element itself is preferably designed in the manner of a leaf spring, the free legs essentially relative to one another should describe an acute angle.

As materials for the electrically conductive parts of the clamp body, so the base body and the spring element should be preferred to be mentioned with regard to the spring element spring steel and with regard to the base body brass or another copper alloy.

The base body is in a further embodiment to be emphasized χ the innovation formed in one piece, the width of the

Guide surface for the leg forming the screwless clamp and the Width of the web connecting the legs to one another are preferably selected to be the same, whereas that having the second guide surface free legs have a large extent with regard to its width in the case of edge regions that have not yet been bent over. To the To form flat receptacles, the edge areas are then crimped. It can then be seen that the widthwise extension of the leg having bent edge regions is less than that of the opposite one.

The clamp body is finally surrounded by an insulating housing, which, for example, can have overlaps in order to engage the clamping body. There can also be a connection between the Insulating housing and the clamping body are carried out by means of welding such as, for example, ultrasonic welding.

Further details, advantages and features of the innovation emerge f from the preferred embodiment shown in the drawing

example .

Show it:

1 shows a perspective view of a clamp body according to the invention and

FIG. 2 shows the clamping body according to FIG. 1 in a side view.

The clamping body 10 according to the invention comprises a U-shaped one Base body 12, which consists of two parallel free legs 14 and 16 and one perpendicular to it Connecting web 18 is made. The inner surface 30 of the leg 14 is designed as a guide surface for a stripped conductor end 34, whereas the outer surface 32 of the leg 16 in turn forms a guide surface for a flat plug 36. The leg 14 or the guide surface 30 now acts with a spring element 24 in this way together that the function of a screwless terminal is given. The spring element 24 is with its free end in the direction of the leg 16 bendable, namely when the conductor end 34 is to be introduced.

The spring element 24, which is preferably designed as a leaf spring is, goes in the embodiment of the inner surface 38 of the

opposite leg 14, one in the leaf spring 24 provided recess cooperates with a bent from the leg 16 tab 40 for fastening. Of course it can Spring element 24 also extend from connecting web 18.

To make the flat plug electrically conductive with the guide surface 32 of the The edge regions 20, 22 are to allow the leg 16 to interact of the leg 16 bent in the direction of the associated guide surface, to form a receptacle. In this case, the free edges 26 and 28 of the bent edge regions 22 preferably extend or 20 in the direction of the guide surface 32 and are sharp-edged formed to possibly formed on the flat connector To be able to scratch off oxidation layers or protective paint layers.

As the side view of FIG. 2 illustrates in particular, the according to the innovation a combination of a receptacle and a screw clamp Representative terminal with regard to the electrical connections to be introduced in such a way that the flat plug having electrical conductors 36 from the back of the U-shaped base body 12 in the area between Guide surface 32 and the edges 26 and 28 is introduced, whereas the stripped conductor end 34 between the parallel Legs 14 and 16 is pushed in the direction of the connecting web 12 between the guide surface 30 and the spring element 24.

Of course, the electrical connection 36 can optionally can also be introduced from the opposite side or the connecting web 18 has an opening in the region of the guide surface 30 have in order to introduce the electrical conductor 34 through this and move in the direction of the free ends of the legs 14 and 16

to be able to. For this purpose, the spring element 24 would have to be bent in its area adjoining the guide surface 30 in the direction of the leg 16 so that the end of the conductor can easily be positioned between the guide surface 30 and the spring element. "4 can, of course, alternatively be ~ <a .-- · -, * (· * · element 24 in the same direction as the U-shaped body M. ·" Met.

* "* Assigns the embodiment to each leg 14 or 16 one

Guide surface 30 or 32 to, so a single leg include both guide surfaces.

To the inserted in the screwless terminal part I conductor 34 again To be able to remove, the leg 14 in the area of the leaf spring 24 has an opening 42 into which a pointed object such as Example, the end of a screwdriver can be inserted in order to bend the leaf spring 24 down in the direction of the leg 16 can so that the conductor end 34 can be pulled out.

The clamping body 10 is supported by an insulating housing (not shown) , ι surrounded, which with that by locking or welding

can be connected.
