Description

1 2585876

  The present invention relates to an interrup-

  thermostatic fan with output connection terminals

  aligned. In standard thermostatic switch types

  maliciously in use, intended more specifically (although not exclusively) for the control of temperature in household appliances such as washing machines, dishwashers and the like, the connection terminals coming out of the

  the body of the thermostatic switch are, for reasons

  sounds of construction, protruding from the body of the inter-

  thermostatic switch and arranged at the periphery on its base.

  stand in staggered positions of 90 relative to each other

  to others. This makes it very difficult to connect with the

  electrical control unit of the machine.

  The purpose of this invention is to provide an

  thermostatic switch of effective connection terminals c -

  venably isolated, arranged in such a way as to enable

  to have an easy and simple connection to the communication units

  machines of any type by means of a

  single node with a standard step.

  The thermostatic switch according to the invention is characterized in that the bottom wall of its body is provided with profiled housings, two of which are arranged one opposite the other and receive the base plates bent to the bracket that are respectively connected to

  two corresponding terminals of the thermostatic switch.

  Both ends of the plates, being perpendicular

  at the base, constitute output connection terminals aligned with other connection terminals that are

  in one piece with the remaining terminals of the interrup-

thermostatic fan.

  The four connection terminals, which are thus aligned, are housed in a housing which can be fixed to the connection terminals themselves and in which housing can be inserted the connector which is itself connected to the circuit

  electrical control of the machine.

  Other features and advantages of the invention

  will appear in the following description.

  In the accompanying drawings, given solely by way of example,

  FIG. 1 is a top view, partially in section

  pe, a thermostatic switch equipped with connection terminals arranged according to the invention, and supplemented with a protective housing for protecting the terminals; FIG. 2 is a top view, in section along the line II-II of the thermostatic switch shown on

FIG. 1.

  FIG. 3 is a top view of the wall of

  the thermostatic switch on which the terminal box is removed; FIG. 4 is a top view of the thermostatic switch of FIG. 1, represented on a smaller scale

than in the previous figures.

  In FIG. 1, the thermostatic switch A, of conventional type, is composed of a cylindrical body 2 made of an insulating material on which is attached to a tight seal, a metal cap 4 provided with a flange 5 which allows to fix the thermostatic switch, for example, to the wall of a container (not shown) in which it is

to adjust the temperature.

  Two terminals 12 opposite to each other are pre-

  views of the bottom wall of the insulating body; the ends of these terminals are connected inside the body of the thermostatic switch to corresponding electrical contacts which are pressed by the blade or blades

  bimetallic (s) of the thermostatic switch.

  In a position perpendicular to said terminals 12 (see Figures 2 and 3) project two opposite rods 15

  connected directly to the internal contacts of the

  thermostatic fan and which in themselves constitute two connection terminals. Both terminals 12 and rods

3 2585876

  are provided with a pair of tongues 13 and 13 '

  which are folded outward to fix these

  elements in the body of the thermostatic switch. The former

  terminals 12 are provided with another pair of lanterns

  14 for the purpose of establishing the electrical connection with

  the base of the other connection terminals, as

will cry lower.

  As can be seen by referring in particular to

  link to FIG. 3, the terminals 12 protrude into

  shaped sections 16 formed in the bottom wall of the body of

the thermostatic switch.

  The housings contain platelets 20

  square brackets whose profiled bases 21 present a

  slot 22 to cooperate with the tabs 14.

  At the end which is opposite the slot 22, each of said plates 20 bent to the square has a rod 24, integral with it, which is perpendicular to the base 21, to form this way the

  two central connection terminals of the thermal switch

  which are adjacent in the inner position and in parallel with the connection terminals 15 which protrude towards

  the outside in opposite housing 26 of the bottom 10.

  The connection terminals 15 and 24 are aligned with

  on each other, with a constant step P which is pre-

  5 mm; they are protected by an addi-

  B of molded plastic material, whose body 30, of generally parallelepipedal shape, is in one piece with the base 32 of this housing, which is provided with slots 34 by means of which said housing can be fitted on the terminals, by thus fixing exactly above the bottom

  of the thermostatic switch body, also thanks

  the housing of appropriate shape provided under the base 32 of the housing, opposite the housing 16, 26 to avoid

  any interference with the wafers 20 in particular.

  On the other hand, the connection terminals 15 and are provided with teeth 36 for fixing the housing B to

  terminals by an irreversible connection operating by snapping.

  The inner face of the bottom of the housing is provided with ribs 38 which act as limit stops for the connector (not shown) which can be moved to

  sliding in the housing and is guided in the latter.

  The insertion of the connector is guided in one position

  possible by offset grooves 40 and 42.

  The description given above and the illustration

  given in the drawings clearly show the purpose of the in-

  vention. The alignment of the connection terminals creates a system

  a quick and convenient connection method that uses a

  between the electronic circuit and the control of the

  machine and the thermostatic switch. The invention is

  mainly involves thermostatic switches

  small dimensions, of the type used in household appliances.

  and who must necessarily be housed in

  restricted spaces or their connection to the

  would require otherwise more time and hand fees

higher workloads.

  The details of the embodiment may

  to be modified, in particular as regards the dimensions

  without departing from the scope of the invention.
