Description

Process for the production of large panel units from molded insulating material with pressed-in metal rails; especially for base plates and housing walls of cable termination devices One endeavors to base plates and housing walls, in particular for cable termination devices, to be made from molded insulating material and mainly to the implementation points to use inserts made of such material. Furthermore is it is known for insulating stolf plates and housings to press in metal parts, see above that you can attach other metal parts for the attachment of the housing or the apparatus parts can attach.

To make such base plates and housing from insulating material expandable design what is particularly suitable for cable termination devices according to the invention the metal rails pressed into the edges of the plates in a manner known per se Grooves for joining together so that large plate units and whole Let housing form.

The joining of the plates with their metal edges can be done in different ways Way done by, for example, the grooves are designed so that the in the specially introduced cavity created by placing two plates together Metal filling causes the cohesion of the panels. The plates can with their Metal edges also soldered to one another or more even with dovetail-shaped edges Formation of the grooves pushed into one another or in any other way with one another get connected.

The drawing illustrates the subject matter of the invention on some Embodiments, namely Fig.i shows a cross section through two joined together, insulating panels with metal edges. 2 shows in the same representation a different design of the metal edges.

According to FIG. I, the plates made of insulating material have i on their edges pressed-in metal rails 2, which in a known manner with approaches 3 provided and either roughened or have abutments 4, so that the Insulating material adheres to them well. On their outer circumference are in the metal rails 2 recessed inclined grooves 5, which in the illustrated embodiment After the plates have been put together, a cross-sectionally cruciform cavity form, to achieve a firm cohesion for the purpose of connecting the plates with one another with a correspondingly shaped metal rod or with one to be hammered Soft metal is filled.

In Fig. 2, the metal rails 2 are with dovetail grooves 6 provided, which are expediently so leg eating that the protruding parts 7 of the Rails fit exactly into the groove of another plate, so that the in the Connection shown in the drawing.

Claims (3)

PATENT CLAIMS; i. Method of manufacturing large disk units äus molded insulating material with pressed-in metal rails, especially for base plates and housing walls of cable termination devices, characterized in that the in the edges of the plates pressed-in metal rails grooves for connecting them together own. 2. Isolierpreßstoffplatte, produced by the method according to claim i, characterized in that the grooved metal rails are designed in such a way that arises in the two plates through the grooves when the two plates are put together The metal filling that is specially introduced into the cavity ensures that the panels are held together (Fig. I). 3. Isolierpreßstoffplatte, produced by the method according to claim i, characterized in that for the purpose of uniform formation of the metal edges all plates have telescoping dovetail-shaped recesses (Fig. 2).
