2. Description of the Related Art For example, in a ball hall, auditorium or passenger ship, a power supply line is laid on a wall or ceiling of a room, and a power consuming device provided with a connection line, for example, an electric light can be connected to the power supply line. . This usually requires a great deal of installation effort, since the supply conductor cores must be removed at the intended connection points and each connecting conductor must be connected to the supply conductor. And the connection must be insulated.

This trouble is caused by EP08173 mentioned at the beginning.
It is mitigated by the known device according to 15A1. This device has a coupling element which consists of an upper part and a lower part, which is fixed to the supply line. A base plate is arranged at the mounting position between the upper part and the lower part, and the base plate projects on both sides,
It has a contact part with both sides as through contacts. On the one hand, the contact portion of the integral connecting element contacts the mutually juxtaposed cores of the supply lines and, on the other hand, the connecting lines leading to the electric lamp. The cores of both wires do not have to be stripped of insulation in this device. However, the insulated connecting core must first be inserted into the groove of the upper part when the coupling element is installed in the field. Only then can the upper part and the lower part be combined with the contact part, with the base plate mounted separately between the two parts. Therefore, also in the case of this device, the labor of attachment is relatively large.

[0004]

SUMMARY OF THE INVENTION The object of the invention is to configure the device mentioned at the outset in such a way that a power-consuming device can be connected to the supply line easily and without increasing the mounting effort.

[0005]

This problem is solved by the present invention as follows.

Connecting the contact part of the coupling element to the connecting core, which is stripped of insulation, in a conductive and rigid manner.

The upper part of the coupling element is a grasping part manufactured by injection molding, the grasping part wet-tightly surrounds the end of the connecting wire and the connection part between the contact part and the connecting core wire, and the contacting part projects from the grasping part. thing.

In the case of this device, the contact part is integrated in the upper part of the coupling element in a pre-manufacturing process. The end of the connecting line is standardly produced in this way. In that case, the integral grasping part of the upper part surrounds not only the terminal of the connecting wire but also the connecting part of the core wire and the contact part. The contact part protruding from the grip part is incorporated in the upper part of the coupling element. The contact moves with the upper part and is positioned. If you combine only two parts, the upper part and the lower part,
The connecting element is attached to the supply line without any further installation work. A conductive connection between the cores of both wires is thereby obtained in a simple manner.

In a preferred embodiment, the upper part of the coupling element has at its end a projection protruding from this element, the upper part being the depression of the lower part mounted on the core wire when the coupling element is assembled by means of the projection. Plugged into. Then the upper part may be adapted towards the lower part with the projection in the rotational position. In the mounting position, the upper part is fixed but separable by the element of the lower part which grips and elastically locks on the one hand by the projection and on the other hand at the opposite end region of the projection,
Combined with the lower part.

Embodiments of the object of the present invention will be described with reference to the drawings.

DETAILED DESCRIPTION OF THE INVENTION A power supply line 1 schematically shown in FIG.
Is laid on the wall or ceiling of a room, for example. The supply line is a flat cable, for example having three insulated cores 2, 3 and 4 (FIGS. 5, 6 and 7), which are installed on a common sheath 5 extending parallel to each other. . The insulated core wires 2, 3 and 4 are preferably arranged on the supply line 1 at intervals. In the embodiment shown here, the supply line 1 has two plastic coupling elements K.
One is attached. A power connection line 6 is connected to each of the coupling elements K, one connection line being connected to a power consuming device, for example a light 7. The detailed structure of the binding element K is described in Figures 2 to 8.

The connecting element K has an upper part 8 and a lower part 9, both of which are fixed in the assembled position, but which are separably connected to each other. The upper part 8 is made of polyurethane, for example, and the lower part 9 is made of polyester, for example. The lower part 9 is an elongated carrier such as a trough and has a storage space whose size matches the size of the supply line 1. The lower part is provided with two side walls 10 and 11 which delimit a housing space and two hooks 12 which can be flexibly bent at both axial ends, and the hooks are bent and overlapped when not in use. In the attached lower part 9, the hook grasps the supply line 1 and the lower part 9
To the supply line. Attached to the lower part 9 is a latch element 13, which can be bent more flexibly. For example, four latching elements 13 are provided, which are paired with each other (FIG. 4) and which are preferably mounted on the periphery of the lower part 9 at the height of the side walls 10 and 11 to the lower part. Side walls 10 and 11 of the lower part 9
Open to the outside and have a bent recess 14
Are provided (FIG. 3).

The upper part 8 of the coupling element K is a grip made by injection molding. The upper part wraps the distal end of the connecting wire 6 and the connecting portion between the connecting core wire 15 and the contact portion 16 connected to the connecting core wire 15 in a moisture-tight manner. The contact part 16 is fixed to a common, plate-shaped carrier 17 made of an insulating material having mechanical strength, for example, glass fiber reinforced polyester. The connecting wire 6 has, for example, three insulated core wires 15 like the supply wire 1. The core wire 15 is stripped of insulation at the end and is rigidly and electrically conductively coupled to the contact 16 by crimping, brazing or welding, for example. Contact part 1
6 is a piercing element having a sharp tip. The contact portion is a tip and projects from the contact surface of the upper part 8. The contact part 16 is axially offset relative to the upper part 8 of the coupling element K, preferably as shown in FIG. Positions are indicated by dotted lines 18, 19, 20.
The cores 15 of the connecting wires 6 have correspondingly different lengths in the upper part 8.

The lower part 9 of the connecting element K can be manufactured completely automatically by injection molding. In order to manufacture the upper part 8, first, the coating at the end of the connecting wire 6 is peeled off, the exposed end of the core wire 15 is cut long, and the insulation is peeled off. After that, the contact portion 16 and the core wire 15 are conductively coupled. Then, the grasping part of the upper part 8 is generated by injection molding. The grasping part
The portion of the connecting wire 6 where the end is not stripped, and the core wire 1
5 and the connection portion of the contact portion 16 are wrapped in a moisture-tight manner. At the end of the grasping portion, a protrusion 21 protruding outward is generated during injection molding.

The coupling element K is attached to the supply line 1 in the following manner, for example.

The prefabricated lower part 9 is attached to the supply line 1 at any point on the extension. Lower part is hook 1
2, the user grasps the supply line 1 by himself. Thereafter, the prefabricated upper part 8 is also inserted by means of the projection 21 into the recess 14 of the lower part 9 and the projection 21 is swiveled on the feed line 1 as a "point of rotation". At that time, the contact portion 16 penetrates the coating 5 of the supply wire 1 and is inserted into the core wire 15 of the connecting wire 6 which is preferably a stranded wire. In the final position,
The latch element 13 of the lower part 9 grasps the corresponding surface 22 of the upper part 8 and locks in this position.
Then, the upper part 8 and the lower part 9 of the coupling element K are
Are coupled to each other. A conductive connection between the cores of the supply line 1 and the connecting line 6 occurs.

In order to further seal the "contact space" of the coupling element K, as shown in FIG.
On the contact surface of the seal 23, such as O-
The ring is attached and the seal wraps around the contact 16 of the upper part 8. The seal 23 is crimped onto the supply line 1 at the mounting position of the coupling element K. Upper part 8
The seal 23 can be an integral type. A suitable material for this type of unit is thermoplastic elastomer (TPE)
Is.
