Longitudinally split sleeve for electrical cables with connecting elements

The invention relates to a split sleeve for electrical cables, in particular connecting or branching muJ consisting of two at their flange-like edges over extension connection elements permanently connectable housing half-shells made of plastic whose connecting elements each consist of a groove and an i] these plug-in clamps exist, each of which is an integral part of the housing half-shells.

In the case of such a sleeve, fertilize the rear of the housing half-shells to open or close the sleeve by means of a lifting device tool provided.

If you now have a single Want to use a tool that is suitable for both closing and opening the sleeve described, this must be used with the Engaging in the undercuts of the housing half-shells of the sleeve designed jaws provide tools so be that the closing and opening jaws can be moved in different directions for their effective actuation. Such a combination tool has a complicated design and is accordingly expensive to manufacture.

The invention is based on the object of improving the longitudinally divided Kebelmuße in that they are both closed in a simple manner by means of a single auxiliary device having jaws that can be moved relative to one another as well as can be opened and also specify a suitable auxiliary device. This task can be accomplished with a Solve longitudinally split sleeve for electrical cables of the type outlined above, in which between the connecting elements for closing and opening the sleeve by means of a single auxiliary device having jaws that can move relative to one another on the flange-like edges of each housing half-shell protruding beyond its parting plane or webs assigned to these and receiving them Recesses are formed in an alternating sequence and mutual arrangement, and at the of the parting plane the side facing away from the housing half-shells of the flange-like edges of the same in the area of each web each have a recess is excluded.

According to the invention at the flange-like edges of each housing half-shell provided, the webs receiving recesses and the grooves associated with the webs enable the insertion an auxiliary device with three mutually movable jaws in different three-point support positions, with the same closing movement of the jaws in one

7344926 06/03/76

Position the housing half-shells together, in the other position, however, are separated from each other.

According to a further feature of the invention, it is advantageous if the height of the webs corresponds to that for separating the connecting elements required opening path and the distance of the bottom of the wells from the parting plane of the housing half-shells is dimensioned in accordance with the closing path required for the connection of the connecting elements, in each case two webs or depressions of the one housing half-shell with the web or the one between them Deepening of the other housing half-shell a three-point support for the auxiliary device to open and close the Form a sleeve. This arrangement results in a favorable ratio of forces between the elastic deformation of the connecting elements required closing or separating forces and those to be applied manually to operate the auxiliary device Force, with the smallest possible opening or closing path of the jaws of the auxiliary device.

Furthermore, in a further embodiment of the invention, it is advantageous if the end faces of the webs and the bottom surfaces of the recesses have undercuts, which are a good approach for form the jaws of the auxiliary device and prevent the jaws from slipping when they are operated.

A preferred embodiment of the designed to close and open the longitudinally divided sleeve, - movable against each other Jaws having auxiliary device is articulated as a pliers-like toggle tool with each other and on projections of interconnected handles hinged jaws formed. Of these jaws of the auxiliary device, one jaw has one at its free end centrally protruding approach and the other

7344926 06/03/76

At its free end, bake open two protruding approaches that protrude from one another. Where is the distance between the two Approaches of one jaw that are equidistant from the central approach of the other jaw are equal to the distance between two adjacent ones Web or adjacent recesses dimensioned one of the housing half-shells.

The invention is illustrated below with reference to one in the drawing Embodiment explained in more detail:

In the drawing shows

Fig. 1 in a schematic representation of a cable sleeve the invention;

2 shows a section of the flange-like edges of two housing half-shells of the same closed together to form the cable sleeve according to FIG. 1;

3 shows the detail of the flange-like edges of the socket housing half-shells in the open state of the sleeve and

Fig. 4 is a front view of the auxiliary device.

According to the main application, the cable sleeve with 1 are the housing half-shells with 2 and 3 and the flange-like edges the same numbered 4 and 5. These are each with one Nut7und one in this pluggable terminal 8 comprehensive connecting elements ^ integrally formed and point in alternating order between each pair of connecting elements each have recesses 20 or webs 21 projecting beyond the parting plane, each recess 20 being assigned a web 21 is. The cross-sections and spacings of the webs 21 and the recesses 20 are dimensioned so that the webs in the intended Relative position of the two socket housing half-shells in the recess

intervene and are guided in these. In addition, in the area of each web on the ropes facing away from it flange-like edge 4 or 5 of each housing half-shell 2 or a recess 22 is provided.

The end faces of the webs 21 and the bottom surfaces of the depressions 22 can have undercuts 31 and 32, respectively to enable the jaws of the auxiliary device 23 to be properly positioned or to prevent a comparison of the same when they are operated. The embodiment of the auxiliary device shown in FIG is designed as a toggle tool 23, which is articulated with handles 24 hinged to one another and with these connected jaws 26,27 is provided, which are also hinged to one another. One jaw 26 points in the vicinity of her at the free end one of this protruding substantially perpendicularly, preferably rounded extension 28, whereas the other jaw 27 of the pliers-like toggle lever tool is in the vicinity its free end has two similarly again approach 28 designed approaches 29, 30. The distance between the two, from central approach 28 of the jaw 26 equally distant approaches 29, 30 is dimensioned so that it is the distance between two adjacent Web 21 or adjacent depressions 22 corresponds to one of the housing half-shells. It goes without saying that the distances between the individual webs 21 and the recesses 20 receiving them or the depressions 22 of the flange-like edges 4 or 5 of the two socket half-shells 2,3 are of the same size everywhere are to be selected if the sleeve 1 is to be opened and closed by means of a single auxiliary device.

To - as can be seen from Figures 1 and 2 - joined together Housing half-shells 2.3 of the sleeve 1 to open, is

three the auxiliary device 23 at the same time so with "webs in engagement brought that the two lugs 29, 30 of one jaw 27 to

When the jaws move towards one another with the required force, for example by means of the handles of the pliers-like toggle lever tool, the two housing half-shells 2.5 of the cable sleeve 1 is caused by overcoming the deformation forces of the connecting elements 6 are pressed apart and thus separated from each other.

To merge the two housing half-shells 2,3 the auxiliary device 23 only needs to be turned around at the same point or offset from this so far that now the central projection 28 of the jaw 26 engages in one of the recesses 22 of the one housing half-shell, while at the same time the two Approaches 29, 30 of the other jaw 27 of the auxiliary device in the opposite recesses 22 of the other housing half-shell

intervention. With the same mutually directed movement of the two jaws 26, 27 of the auxiliary device as before now a merger of the two sleeve half-shells is achieved.

It goes without saying that this process depends on the size of the sleeve and the number of connecting elements provided on it can be repeated a few times in order to achieve a complete separation of the two housing half-shells or their complete merging to effect.
