DE3433464A1 - Push-on collar for medium-voltage cables - Google Patents

Abstract

The invention relates to a push-on collar for medium-voltage cables. This collar includes a collar tube (11) which has a smoothing sleeve (12) which is incorporated into the tube wall and surrounds the actual conductor connecting point at a distance. The object now exists of creating a suitable connector which not only connects the two conductors but also produces the contact between the conductors and the smoothing sleeve. This object is achieved in that two solid half shells (8, 9) connect the two conductors (7), the half shells being designed such that they fill the entire space between the conductors (7) and the smoothing sleeve (12) and hence ensure that a good contact is made between these two parts. <IMAGE>

Description

Slide-on sleeve for medium voltage cables

The invention relates to a slide-on sleeve for medium-voltage cables according to the preamble of claim 1.

Such a sleeve is already known (DE-OS 31 42 191).

In this case, the conductor ends are connected by a compression connector. The conductor connection area that extends from the conductor insulation of one end of the cable extends to the conductor insulation of the other end of the cable is of two contact support half-shells surround. These two half-shells, made either from one metal or from one Made of conductive plastic, have end faces that the respective conductors to contact. The outer surfaces of the ileal shells are cylindrical and stand in this way with a Clättungshülse integrated in the socket body in contact. For the connection of the conductors and the contact with the smoothing sleeve are therefore three parts are required, namely the compression connector and the two contact support half-shells.

There are also screw connectors already known that have an eccentric Have a seat to the ladder level and therefore have no support and contact function like the Above mentioned contact support half-shells can take over.

The invention is therefore based on the object of a slide-open To develop sleeve of the type described above, in which the functions of the Connecting and contacting, including setting, are combined.

This object is achieved according to the invention by the features in the characterizing part of the claim 1 specified constructive measures solved.

The advantages achieved by the invention are that the number the parts in the connection area of a sliding sleeve is reduced.

Training and further developments of the object according to claim 1 are the Refer to subclaims.

So it proves to be useful to have the valley shells with the same wall thickness to be provided, with which the prerequisites for a centric seat to the ladder level are created (claim 2).

To improve the clamping technique, it can be advantageous to use the clamping beds to be provided with the same and / or different profiles (claim 3). Particularly It is useful here, the clamping beds with a groove and / or cam profile equip (claim 4).

In the end, the contact can still be made through a special contact layer be improved on the clamping beds, including, for example, a contact paste from Advantage is (claim 6).

An embodiment of the invention is shown in the drawing and is described in more detail below. They show: FIG. 1 a medium-voltage cable mitaufschiebbaren sleeve, in section Fig. 2 one consisting of two half-shells Connector, viewed from the side and partially in section Fig. 3 in Front view and partially in section FIG. 4, this connector in the inserted state, in front view and partially in section As Fig. 1 shows, there are two cable ends 1 and 2 are provided, which are to be connected to one another. this is what the two Cable initially except for conductor insulation 6 and in the immediate connection area Deposed except for their ladder 7. Field control bodies are attached to the cable ends prepared in this way 3 and 4 pushed on, each containing a field control funnel 5.

The conductor connection area that extends from the conductor insulation 6 one end of the cable extends to the conductor insulation 6 of the other end of the cable, is surrounded by a cylindrical hollow body, which consists of two massive metal shells 8 and 9 consists.

The metal shells have the same wall thickness everywhere and are designed so that they take up the entire space between the conductors 7 and a smoothing sleeve 12 which is inserted in a socket pipe covering the merging point 11 is integrated. Imine good contact between the conductors and the tialbschalen is achieved in that the hollow cross-section inside the half-shells is smaller than the conductor cross-section.

Both half-shells are connected by screws 10 (not shown), for which the half-shells are equipped with corresponding holes 17 and 1o. To the One of the clamping beds 13 with a groove profile is used to improve contact and the other Klemitett 14 is provided with a cam profile 16.

According to Fig. 2 and 3, the two ilaibschalen are shown as it would correspond to its original undivided state. By taking it out of material in the longitudinal section is the reduction of the cross-section in the hollow area achieved. The two ileal shells contain holes that correspond to one another, one of the Malb shells each having a threaded hole 17 and the other half-shell a two-stage bore 18 contains.

The step 19 is sunk so far that the screw head is completely Tightened screw is arranged completely within the half-shell profile. The contact between the conductors and the half-shells can be optionally with a contact layer 20, for example by means of a contact paste to enhance.

Fig. 4 differs from Fig. 3 by the inserted conductor 7 with tightened screws 10. In the present case, only the socket pipe is left 11 (not shown) to postpone. - blank page -

Claims (6)
