" Moisture-proof connection and junction box for multi-core electrical cables "

The subject of the present hiring is a particular advantageous one designed moisture-proof connection and junction box for outdoors reap, multi-core laid in damp rooms " electrical lines or cables, such as telecommunication cables etc.

2a of the electrical installation or. Telecommunications are branching or junction boxes for similar purposes already known, however they do not have the special door parts of the present wage, which was based on the task, a particularly useful means both for connecting and for branching multi-core lines also create that is moisture-proof, light and versatile, for wall and pole mounting as well as for cantilever suitable arrangement in connection with aerial cables and had to be particularly shock-resistant for outdoor use

Diftse requirements are met by an essentially rectangular shape Junction and junction box made of insulating material, the has the following special features reap, new and advantageous features ι

The housing is slightly curved outwards on all sides, i.e. both the side surfaces as well as the base and cover have convex curves, which give the housing a particularly high mechanical level Strength or stability against impacts or other mechanical Stresses and has received a very good shape »

The line entry openings are preferably only located in the broad sides of the housing, which best meets the wiring requirements, since connecting spaces of the same size are available for all lines entering the housing. In addition, this arrangement of the entries for the manufacture of the housing is special in terms of pressing technology of the gate part.

Between the inlets provided on both broad sides of the can, there are awei insulating bodies with the in the can center plane necessary contact clamps one above the other, the lower one of which is wider al · the upper »eo that auowÄie ^ KXemmen the lower body · about * are visible and sugänglioh when the upper body is in the doee brought in and peeled off whatever is necessary The search for disruptions has a favorable and work-supportive effect · Pureh die Arrangement of the contact terminals in swei separate insulating bodies In addition, the maintenance work is substantially borrowed. Also · The effect of facilitating maintenance is that the dividing line swi » see the lower part of the housing and the cover as far as possible below. * AeJ the upper clamp body with removed deodorant practical at * the do ·· stands. In order to keep the body in the middle of the can, the lower body has unusual roundings, the pillar-like Torsprüng · Ia reach around the interior of the housing »during the upper · The body is preferably held in the middle plane by reaching into the lower body

Xn are located in the columnar projections of the interior of the can the mounting holes for the wall or pole mounting of the box, which have thus been fully incorporated into the form of the So ·· and their appearance - especially in a self-supporting arrangement where none Fastening holes are required - do not disturb "The screws, bolts or the like that are only used to fasten the box" will change largely absorbed by the effects of the weather, as the fastening holes form closed channels

For the recording and connection of the self-supporting sole * cables existing strain relief β baw. su their grounding does the Do ·· have a contact ring resp. Contact frame »of Middle part lying on the bottom of the can soooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooofbottom Hold central position

Si · Inner parts of the Do ·· - Erdungering, lower body »upper Body - and can be removed from the house underneath and are in closed state of the Do ·· duroh «in the deekel arranged • ommidruokstuek pressed on top of each other and against the bottom of the can, see above dsJ they are immovable

Finally, the can has swiaohen lower body and can bottom

Advantageously, there is no hollow space that is subdivided several times, on which a continuous pulling of line cores from one to the other Hem body side permitted and can be kept in a variety of ways * makes a significant contribution

The drawing shows a top view (Fig. 1) and is rare (Fig. 2) with partially sectioned representations, a precautionary embodiment of the can according to the present bulge, which is described in the following

The lower housing part 1 with arched sides 2 and also arched bottom 3 is laterally provided with gate “cracks 4” protruding into the interior space, in which the fastening holes 5 are arranged ”which terminate in feet 6 at the bottom. In the broad range of the lower housing part 1 there are breakable, pre-formed insert openings 7 in the corners of threaded bushes β and on the floor of the interior ribs 9 which subdivide a cavity 10 provided there in several ways. In the sink area of the housing base * 1, a roof frame 11 with IGLemmstreift ^ I2 _; and screws 15 »a large clamp body 14 with clamps 15 and screws 16 and a small clamp body 17 with clamps 18 and screws 16 one above the other. Brdungerrahmen 11 and large clamp body Hbosltscn laterally roundings 19 »which lead to the gate projections 4 of the housing lower part 1» while the small clamp body 17 has an approach to guide »which engage in corresponding recesses 21 of the large clamp body 14. The domed cover 22 with Guami diaphragm ring 23 and screws 24 covers the lower part of the housing 1 "with an edge 25 of the latter being pressed into the die ring 23" while an Oummidruokstüek 27 adhering in a hole 26 of the deodorant 22 presses on the small terminal body 17 and thus all internal parts of the box are fixed in the lower part of the housing.

The special features of the present gauging can of course next to the example shown and described here auoh nooh You can find your Kledersohlag in completely different constructions, but the box shown could be modified in many ways. 80 would it be s.B. Possibly »more than two, or even just one body shell to be provided» on the narrow sides of the housing more Arranging flow openings »giving the can an essentially square shape, etc.
