Electric Circuit Arrangement
for Mains Connection
The present invention relates to an electric circuit
arrangement for mains connection.
In many industrial and domestic fields, the need for a
versatile mains connection technique increases in order that
not only many consumers may be connected to an existing
mains socket, but also that low-voltage apparatus may be
connected and switching means interconnected.
Existing connection strips provided with a plug cord cannot
fulfil these demands, even if these connection means are
provided with an on-off switch and in most cases comprise
several sockets.

~her0fore, a primary object of the present invention is to
create an electric circuit arrangement for mains connection
which meets practically all requirements in regard to
possible connection, transformation and switching
techniques.
This is achieved according to the invention in the first
place by modules, detachable circuit construction units that
are current-conductive and connectable to one another.
In this connection, it is of advantage that at least one
circuit construction unit is constructed for a mains socket
connection having a plug cord or as a plug.
Further, in order to make the circuit arrangement childproof
or safe against mechanical stress, it is of advantage that
the current-conducting connecting means of the circuit
construction units simultaneously fo~m interlocking means;
and/or that the circuit construction units comprise in
addition interlocking means.
For an optimum handiness, it is further of advantage that
the circuit construction units are constructed cubical or
quarter-shaped and have connecting means on at least two
sides.

For a current-contact protection, the circuit construction
units can, moreover, be closeable on the connecting-means
side by means of small contact-protecting plates.
In order to attain a wide range of applications, it is
essential to the invention that the circuit construction
units are constructed as, among other things, an on-off
switch or a power circuit-breaker, as a transit block or
preferably a switchable transformer, as an individual
socket, as a plug switch, as a multiple-socket strip or
board, as a dimming switch, as a switching-on lag switch
or potentiometer or connecting piece or branching or the
like.
Further, according to the invention, the current-conducting
connecting means can ~e flat or round plug pins and plug
sockets or turning-lock contact means or slot contact means;
and, furthermore, the additional locking means can be screw
connections or swivel means or locking slide means.
Exemplary embodiments of the invention will now be more
particularly described with reference to the accompanying
drawings in which:

modular circuit construction unit shown in two
elevations;

modular circuit construction unit shown in two

circuit construction units with different
contact connecting means; and
IG. 8 a - d is a diagrammatic representation of modular
circuit construction units with different
interlocking means.
As the representations of the drawings show, the electric
circuit arrangement for mains connection distinguishes
itself according to the invention by modules, detachable
circuit construction units that are current-conductive and
connectable to one another 1 - 20.
As FIGS. 1,2 and 4a show, at least one circuit construction
unit 1,2,7 is constructed for a mains socket connection
having a plug cord 1'j2 or as a plug 7.
As FIGS. 1 to 6 show in particular, the circuit construction
units can be constructed as, among other things, an on-off
switch or a power circuit-breaker 1, as a transit block or
preferably a switchable transformer 2, as an individual
socket 3, as a plug switch 7, as a multiple-socket strip or
board 8, as a dimming switch 19, as a switching-on lag
switch or potentiometer or connecting piece or branching or
the like (not shown).

Of course, other circuit elements in addition to those here
are, moreover, capable of being developed and adapted as
modular circuit construction units.
In order to make a circuit arrangement consisting of a
plurality of such circuit construction units as previously
described safe against mechanical stress or childproof, the
current-conducting connecting means of the circuit
construction units can simultaneously form interlocking
means 4' - 6' or 10' - 13' according to FIG. 7 a-g.
Further, the circuit construction units can, of course, also
comprise additional locking means 14' - 17', as Figures 8
a - d illustrate. In which case, these interlocking means
can be screw connections 14', 15' or hinge means 16' or
locking slide means 17'.
For an optimum handiness, it is further of advantage that
the circuit construction units are constructed cubical or
quarter-shaped and have connecting means on at least two
sides (all Figures).
For a current-contact protection, the circuit construction
units 20 are, moreover, closeable on the connecting-means
side by means of small contact-protecting plates 20', as
2~6~ 6~
FIG. 5 illustrates in particular.
As FIGS 3 and 7 show in particular, the current-conducting
connecting means can be flat or round plug pins and plug
sockets 3',4',6' and 5' or turning-lock contact means 10',
11',12' or slot contact means 13'.
Thus from the aforementioned there results a modular
electric circuit arrangement for mains connection for a
practically unlimited applicability.
Naturally, in this connection, there are no limits to a
further development, so far as the other specific embodi-
ments are based on the modular circuit construction units
according to the invention.
