Fig. 5 is a plan view of a slide tongue as a clamping member the second embodiment and

Fig. 6 is a broken longitudinal section through. a tail light with the second embodiment .. The first embodiment according to FIGS. 1 and 2 has an insulating material Material such as a hard plastic material, molded support 10, to which a conductor element 12 is connected, The carrier 10 forms, for example, a socket which is intended to receive the base of an incandescent lamp (not shown). That Conductor element 12 is then intended to be in contact with one pole, be it the positive one, of the incandescent lamp during the other pole comes into contact with another conductor element 14, which is attached to the carrier 10 in a suitable manner. A movable clamping member (16) is mounted on the carrier 10, which, as will be understood further below, is intended to be the bare end 18 of an electrical glue which can be seen in FIG 20 to keep in contact with a conductor tongue 22, which is formed in one piece with the LeiteisLemant 12: ldet or electrically conductive with this is connected.

In the exemplary embodiment, the clamping member has the shape of a slide 16, which slides on a guide in one formed in the carrier 10 Cavity 24 is arranged. The end 26 of the slide 16 passes through an opening 28 in the corresponding cross section Bottom of the cavity 24 and has a projection such as the tooth 30, which strikes the carrier 1O, thus releasing the slide 16 is prevented by the carrier 10.

It is noteworthy that the opening 28 as well as the shape of the cavity 24 are designed so that one of the sides of the slide 16, namely the side 32, - practically during the entire shift of the slide 16 remains in contact with the conductor tongue 22. Of the Slide 16 has a transverse opening 34, which in the starting position shown in Fig, 1 of the slide 16 opens outside the cavity 24 on both sides into the open, so that

from there the easy insertion of the bare end 18 of the line 2O in the breakthrough 34 is possible.

So that the slide 16 is held with a certain force in its end position shown in Fig. 2, is on the on the other side 36 of the slide 16 a slight hump 38 is provided which cooperates with the opening 28. When you get the slider 16 presses into the cavity 24 ·, namely the hump is forced through the opening 28, which is thanks to the elasticity of the support 10 and / or the slide 16 is possible, and he then exercises one when the slide 16 has once reached its end position some resistance to pulling the slide out of the cavity 24.

The slight widening of the edge of the opening is noteworthy 28 against the interior of the cavity 24, which on the one hand bring the passage of the tooth 30 with regard to the positioning of the slide 16 and on the other hand the passage of the hump 38 with a view to holding the slide 16 in its' end position relieved.

The slide 16 is completed by at least one projection, namely a transverse tooth 40, which in cooperation with the wall 4 4 of the cavity 24 opposite the conductor tongue 22, a retaining means for clamping the flexible ones Sheath 42 of the line 20 forms.

As in the exemplary embodiment, the slide 16 can also have one Have foot 46 or some other Lascha that facilitates its handling.

In a variant of the first embodiment, not shown the small organ is mounted on the carrier so that it can pivot around one end, wherein the cavity can be designed as a simple recess that receives the clamping member in its end position. The restraint is modified so that there is a shift of the small organ in its starting position by turning Evacuation of the cavity, i.e. the recess, is prevented. The attachment of the quick connection according to FIGS. 1 and 2 is easy understandable:

First, the bare end 18 of the electrical line 20 is so inserted far into the opening 34 in the slide 16 that it 1-sees protrudes beyond the slide side 32, whereupon the slide 16 is moved from its starting position into its end position. The bare end 18 is bent over against the foot 46 (a bend created by a suitable bent section the conductor tongue 20 can be supported) and then between the slide side 32 and the conductor tongue 22 constrained. At the same time, the tooth 40 on the side 36 easily penetrates the jacket 42 of the line 20, the latter to the wall 44 of the cavity 24 is created. At the end of the displacement, the hump 38 crosses the opening 28 and thereby holds the slide 16 and the line 20 in the final state shown in FIG.

The squeezing off of the bare end 18 between the slide 16 and the conductor tongue 22 simultaneously ensures one good electrical contact and effective mechanical retention of the line 2O. The interaction of the tooth 40 and the Wall 44 also improves the mechanical properties due to the resulting clamping effect on the jacket 42 of the line 20 Hold the bare end 18 of the line 2O on the carrier 10. In addition, a strain relief of the bare end 18 is connected.

In Fig. 3, a tail lamp 50 for vehicles is shown in which the first embodiment is used. The tail lamp 50 comprises a member made of molded plastic carrier body 52, fastened in a suitable manner on the carrier housing 52, in turn, for example, a back ¹ · radiator 56 bearing cap 54 and a light bulb 58, with which a mirror is connected 60th The support housing 52 forms a socket for the base 62 of the light bulb 58. The central negative pole of the light bulb 58 is connected via the conductor element 14 to a ground connection 64 which passes through the support housing 52 and is advantageously used to attach the tail light 50 to the vehicle. The ring-shaped positive pole of the incandescent lamp 58 is in contact with the other conductor element 12. The slide 16 now allows the bare end of the electrical line, not shown, to supply the

7539918 08/04/77

To attach tail light 50 to the conductor tongue 22, which is in one piece is formed with the conductor element 12, which in reality represents an extension of the conductor tongue 22.

In the context of the invention, numerous changes are. first embodiment possible, which relates in particular to the Form of the small organ and the manner of its displacement on which Formation of the retaining means, which holds the clamping member in its • Enstellung, on the shape of the cavity and that of the conductor tongue as well as relates to the number and arrangement of the teeth.

In the second embodiment according to FIGS. 4 and 5, the parts the same or similar parts to the first embodiment denoted by reference numbers 100 higher.

The second embodiment also has one made of insulating material cast carrier made of hard plastic on, to which a conductor element 112 is connected. The carrier forms, for example, a socket that is used to accommodate the in Figure 4 with dashed lines indicated base 162 of an incandescent lamp, otherwise not shown, is used. The conductor element 112 is so here formed by the surface of the ring-shaped contact area, softer the poles of the incandescent lamp, namely the positive, represents, while the other pole comes into contact with another LeiteiELement not shown in Fig. 4, the is attached to the carrier 110 in a suitable manner. A clamping member (116) is in turn mounted on the carrier 110, which is intended to have the bare end 118 of an electrical line 120 in electrical connection with the conductor element to keep.

In the exemplary embodiment, the clamping member has the shape of a slide tongue 116 slidable on a guide in a cavity which is delimited on one side by a guide track 124 in the carrier 110. The protruding end (126) of the slide tongue 116 has the shape of a curved, elastic finger 126, which in the end position of the slide tongue 116 shown in FIG. 4 with solid lines in a recess 128 engages in the "socket part" of the carrier 110 so that it

7539918 08/04/77

on the one hand comes into contact with the conductor element 112 and on the other hand at the same time the slide tongue 116 in its illustrated end position holds by the finger 126 wi rkt with the edge of the recess 128.

The slide tongue 116 also has two pairs of teeth or projections or lugs 130 and 138 (which can be obtained, for example, by stamping) which cooperate with two / closed straight grooves 131 in the guideway 124 in order to move the slide tongue 116 towards it lead and to the detachment of the sliding tongue before assembly of the line 120 (by interaction of the tabs 130 with the bottom of the grooves 131 in the guide track 124) and the displacement of the sliding tongue in Auszugsrich- \ processing (by interaction of the tabs 138 again with the Reason to oppose the grooves 131 in the guideway 124) when the sliding he zxinge has been pushed into its end position once.

It is noteworthy that the shape of the guide track 124 in the cavity is chosen so that one side of the slide tongue 116, namely the side 132, during the entire possible displacement of the slide tongue remains closely adjacent to the wall 133 of the cavity, which is located between the grooves 131, with a view to pinching the bare end 118 of the lead 120, as further becomes understandable below.

The slide tongue 116 has a transverse opening 134, which is shown in FIG. 4 with dashed lines Starting position of the slide tongue outside the cavity of the carrier "! 0 opens out into the open on both sides, so that from there easily the bare end 118 of the line 120 into the Breakthrough 134 can be introduced. The free end 146 of the slide tongue 116 is bent over to make it easier to operate is. It also has a breakthrough 147 for the line 120 to pass through.

The wall 144 of the cavity in the carrier 110 opposite the wall 133 has an angular projection 141 which, in cooperation with the slide tongue 116 a means for clamping of the insulating, flexible jacket 142 of the line 120 forms.

In a variant of the second embodiment, the slide tongue has between their two openings a projection or a tooth, which is in the opposite direction to the direction of the noses 130 and 138 extends. This tooth interacts with the wall of the cavity in the carrier, which wall has the recess, to form the jacket clamp the cable and thereby fix the cable mechanically on the carrier.

The attachment of the second embodiment according to FIGS. 4 and 5 is easy to understand: First, the bare end becomes 118th the electrical text 120 inserted so far into the opening 134 of the slide tongue 116 that it protrudes slightly over the side 132, whereupon the slide tongue 116 from its starting position in their end position is pushed. During this shift, the bare end 118 is bent over onto the side 132 (which passes through. a suitable slope 148 can be supported on the wall 133 of the cavity) and it is then placed between the side 132 of the Slider tongue 116 and the wall 133 wedged. At the same time, the projection 141 on the wall 144 easily penetrates the jacket of the line 120 and places it on that of the slide tongue 116 opposite side. At the end of the displacement, the lugs 138 penetrate the grooves 131 so that they the slide tongue 116 and hold the line 120 firmly in the final state shown in FIG.

The squeezing off of the bare end 118 between the slide tongue 116 and the wall 133 ensures a good electrical connection at the same time Contact and an effective mechanical holding of the line 120. The interaction of the projection 141 and the The slide tongue 116 also improves the resultant clamping effect on the jacket 142 of the line 12o the mechanical fastening of the bare end 118 of the line 120 to the carrier 110, with which a strain relief of the line 120 is connected is.
