with a conductor element arranged on a carrier

609826/0302

Telephone information and orders are only binding after written confirmation

The invention relates to a device for the quick connection of the end of an electrical supply line to a a carrier arranged conductor element.

With the majority of the quick connections currently on the market a kind of elastic clamp with three legs is used, with the end of the supply line between the middle leg on the one hand and the two outer legs on the other hand is clamped. With such devices remains however, the holding force acting on the line is weak.

The invention is therefore the task of zugrur.de to create a device of the type mentioned, which holds the end of the line permanently on the conductor element. According to the invention, this object is achieved by a movable one Clamping element which is provided with an opening for the passage of the bare end of the electrical line and which is on the Carrier is displaceable into an end position in which it holds the bare end in electrical contact with the conductor element. Refinements and developments of the device according to the invention are contained in the advantageous and therefore preferred embodiments of the device according to the invention 2 to 9 marked.

The invention also consists in the use of a device according to any one of claims 1 to 9 for connecting an electrical Power supply line with the positive pole of the incandescent lamp of a tail light for vehicles that have a carrier housing and one of these has final, translucent colored cap.

In the following, the invention is based on two embodiments of the invention illustrated by way of example in the drawing Device explained in detail. Show it:

Fig. 1 is an enlarged cross-section of a

first embodiment in the initial state; FIG. 2 shows an illustration corresponding to FIG. 1 of the first embodiment in the final state; FIG.

Fig, 3 is a longitudinal section through a tail light with the first embodiment;

609826/0302

4 shows an enlarged and broken away cross section by a second embodiment;

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 hard plastic material made, 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 determined, with one pole, it let the positive one be in contact with the incandescent lamp, while 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 line shown in FIG 20 to keep in contact with a conductor tongue 22, which is formed in one piece with the LeiteisLement 12 or electrically conductive with this is connected.

In the exemplary embodiment, the clamping member has the shape of a slide 16, which is arranged to slide on a guide in a cavity 24 formed in the carrier 10. The end 26 of the slide 16 passes through an opening 28 corresponding to its cross section in the base of the cavity 24 and has a projection like the tooth on, which strikes against the carrier 10 so that a detachment of the slide 16 from the carrier 10 is prevented.

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 displacement 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 of the slide shown in FIG 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 20 in the opening 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 the slide 16 is pressed into the cavity 24, the hump becomes pushed through the opening 28, thanks to the elasticity of the carrier 10 and / or the slide 16 is possible, and he then exercises, once the slide 16 has reached its end position, a 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 44 of the cavity 24 opposite the conductor tongue 22, a retaining means for clamping the flexible 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 tab that facilitates its handling.

In a variant of the first embodiment (not shown) the clamping member is mounted on the carrier so as to be pivotable about its one end, the cavity being designed as a simple recess can that receives the clamping member in its end position. The restraint is modified so that there is a shift of the clamping member in its starting position by turning when clearing the cavity, i.e. the recess, prevented. The attachment of the quick connection according to Fig. 1 and 2 is easy to understand: ·

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

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

In Fig. 3, a tail lamp 50 for vehicles is shown in which the first embodiment is used. The tail light 50 has a carrier housing 52 made of molded plastic, a cap 54 which is fastened in a suitable manner to the carrier housing 52 and in turn carries, for example, a reflector 56, and an incandescent lamp 58 to which a mirror 60 is connected. 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

609826/0302

Tail light 50 to be attached 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 to the first embodiment are possible, which relate in particular to the Shape of the clamping member and the type of its displacement to which Formation of the retaining means, which holds the small organ in its enstollung, 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 a cast carrier made of insulating material such as hard plastic, to which a conductor element 112 is connected. The carrier forms, for example, a socket which serves to accommodate the base 162, indicated by dashed lines in FIG. 4, of an incandescent lamp, otherwise not shown. The conductor element 112 is thus formed here by the surface of the ring-shaped contact area, which represents one of the poles of the incandescent lamp, namely the positive one, while the other pole comes into contact with another conductor element, not shown in FIG is expediently attached to the carrier 110. On the carrier 110 , in turn, a clamping member (116) is mounted, which is intended to hold the bare end 118 of an electrical line 120 in electrical connection with the conductor element.

In the exemplary embodiment, the clamping element has the form of a slide tongue 116 which is arranged to slide 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 slider tongue 116 in the form of a bent, resilient finger 126 which engages in the illustrated in Fig. 4 with solid lines end position of the slider tongue 116 in a recess 128 in the "socket member" of the carrier 110, so it that one-

609826/0302

on the one hand comes into contact with the conductor element 112 and on the other hand at the same time holds the slide tongue 116 in its illustrated end position by the finger 126 cooperating with the edge of the recess 128.
The slide retainer 116 also has two pairs of teeth or projections or lugs 130 and 138 (e.g.

ends are available through stamping), which with two / closed straight grooves 131 in the guide track 124 cooperate to the To guide the slide tongue 116 on it and in order to prevent the slide tongue from becoming detached before the assembly of the line 120 (by working together the lugs 130 with the bottom of the grooves 131 in the guide track 124) and the displacement of the slide tongue in the pull-out direction (by the interaction of the lugs 138 in turn with the bottom of the grooves 131 in the guideway 124) when the Slide tongue 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 Page 132, throughout the possible displacement of the slide tongue remains closely adjacent to the wall 133 of the cavity, which is arranged between the grooves 131, with a view to pinching the bare end 118 of the line 120, as further becomes understandable below.

The slide tongue 116 has a transverse opening 134, which is shown in FIG. 4 with dash-dotted lines Starting position of the slide tongue outside the cavity of the carrier 10 opens into the open on both sides, so that from there the bare end 118 of the line 120 can easily be inserted into the opening 134. The free end 146 of the Slide tongue 116 is bent over so that it is easier to operate. It also has an opening 147 for the passage of the line 120 on.

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

609828/0302

In a variant of the second embodiment, the slide tongue has between their two openings a protrusion or a tooth, which is in the opposite direction to the direction of the noses 130 and 138 extends. This tooth cooperates 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 118 becomes the electrical line 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 is pushed from its starting position into its end position. Suffering from this shift the bare end 118 a bend on the side 132 (which through a suitable bevel 148 can be supported on the viand 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 protrusion 141 on the wall 144 easily penetrates the shell 142 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 the line 120 fixed in that shown in FIG Hold final state.

The squeezing of the bare end 118 between the slide tongue 116 and the wall 133 simultaneously ensures good electrical contact and effective mechanical retention of the Line 120. The interaction of the pre-jump 141 and the slide tongue 116 also improves as a result of this resulting clamping effect on the jacket 142 of the line 120 the mechanical fastening of the bare end 118 of the line 120 on the carrier 110, with which a strain relief of the line 120 is connected is.

From Fig. 6 a tail light 150 for vehicles can be seen, in which the second embodiment according to FIGS. 4 and 5 is installed is. The tail light 150 has a molded plastic

609826/0302

Fabric-made support housing 152, a suitably attached to this, in turn as a support for a reflector 156 serving colored cap 154 and a light bulb 158 connected to a mirror 160. The carrier housing 152 forms a socket for the base 162 of the incandescent lamp 158. The central negative pole of the incandescent lamp 158 is through the conductor element 114 with a Ground connection 164 connected, which crosses the support housing 152 and advantageously for fastening the tail light 150 is used on the vehicle. The ring-shaped positive pole of the incandescent lamp 158 forms the surface of the conductor element 112, which is appropriate through the slide tongue 116 electrically to the end of an electrical supply line (not shown) for the tail light is to be connected.
