Metallic cover for a surge arrester.

Me invention relates to a setallisebes Abschlussstüek for a surge arrester * & as from a äes on äem a Sn € e a AEIE electrodes -Ableiters containing glass body attached Eappe xmä from a Sontaktfahne best at * AEIE with OCE one electrode siittels a vitreous eingescßlossenen pin VETH \ Mueen is * Such surge arresters, which are also called Sasentladusgsabler »are required for! telecommunication systems to divert overvoltages» the aurcii lightning failure »induction, static charge and the like, verisrsaeat.

This is the case with the known surge arresters End piece made of two different ropes, of course.

a cap and a contact tab. As this, two parts have a completely different porm, they are divided into two drawn in various operations and then put together, e.g. welded together The invention is now based on one task - a blouse to create that can be produced much more easily «

Another disadvantage of the known end pieces is in that the connection pin between the electrode and the contact tab is soldered or welded into the contact tab If the glass body is made of HarigLas, a molybdenum pin is required as a connecting pin This molybdenum pin cannot go directly into the contact tab be soldered in or welded in · From .this Basically, an intermediate metal is created between the Holybdan pin and the contact flag, which is made of brass in the Hegel. E.g. «nickel., Needed that with both the molybdenum and with the brass of the contact lug by welding or iiötung is connectable «The invention is therefore based on the - another task based on creating a final piece, desBen contact lug as easily as possible with the connection pin is connectable.

Both of these objects are thereby achieved according to the invention
solved that the cap and the one with a recess for
The flag provided with the connecting pin forms a homogeneous end piece. Bas new, forming a homogeneous piece
The end piece can be used in a manner known per se, for example

Extrusion process, produced ere. Through this
simplified production of the end piece can
this can be produced with a lesser amount of material
In the transition from the cap to the contact flag
no corrosion or the like occur, as is the case with welding
or soldering points are not excluded without any special effort
can be. Since the material also of the PliessDress- Ί procedure articles made of plastic is provided as a% of the material soaked objects may occur when / j Abschlusstüok according to the invention the connection between the -Λ Eontaktfahne UNAE the connecting pin by simple J | Pressing together the contact flag can be achieved by 4 of these simpler options for creating the closing piece according to the invention, this is much more economical - 1 lighter than the known closing pieces * In addition, the new closing piece is much more durable because, as 1 already mentioned, in the transition between the cap and the n | No corrosion can occur on the flag and by pressing the connecting piece into the flag, a perfect connection of the flag with your pin is guaranteed.

To facilitate the insertion of the connecting pin into the To simplify the contact flag as possible, karm in the In the flag, a recess can be provided, the recess of which extends approximately perpendicular to the contact surfaces of the flag The side walls in the part facing the cap diverge like a funnel in the direction of the cap. This funnel-like diverging side walls of the gap ensure safe and trouble-free insertion the pin into the recess in the flag.

Other features of the invention emerge from FIG following description of an embodiment shown in the drawing.

Show it;

Pig. 1 a section running perpendicular to the contact surfaces of the contact tab by a broken surge arrester according to the Ir-. finding,

FIG. 2 shows a section parallel to the contact surfaces of the contact lugs according to FIG line II - II in Fig. 1

and FIG. 3 shows a frontal view of the surge arrester behind Pig. 1.

The surge arrester shown in the drawing consists of an approximately cylindrical glass body 1, in which a connecting pin 2 for an electrode at both ends melted down, is. This pin 2 protrudes from the end of the glass body 1 sit a part 2 *.

Each end of the glass body 1 is in a kappenfönaigen for 4 a metal designated as a whole with 5 End piece cemented. The end of the flap 4 sent the end piece 5 is designed as a flat contact tab β, in which a recess 7 is provided, which is approximately perpendicular to the contact surfaces 6 'of the flag 6 extending side walls 8 in the cap 4 turned Feil the recess in the direction of aur cap 4 funnel. good-, parting "

When inserting the glass body 1 into the cap 4, the part 2 of the connecting pin 2 engages in the funnel-like extension of the recess 1 and is securely inserted into the part of the recess 7 that forms a bore 7 * through the funnel-like susaaiaenlaufenden Ylänä-e Q. XJm to establish a firm contact between the pin part 2 'and the contact lug β, the contact surfaces 6 ^{1 are} firmly pressed together after the insertion of the pin part 2', so that between the

Flag 6 and the

Pin part 2 ^f creates an intimate contact.

The end piece consisting of the cap 4 and the flag 6 is produced in a manner known per se using the extrusion molding process
Appropriate methods are used. Is desirable
that the material of the end piece has a certain plasticity, so that when the contact lug is pressed together, perfect contact is created between the contact lug and the connecting pin part 2 * *
