This design of a so-called card relay means that a large number of Contact possibilities reached.

There is such a relay is known in which a L-shaped hinged armature actuates several nested insulating pins, each of which have two upward-facing pins that fit into corresponding ones; f engage recesses in the spring sets. Here it is

disadvantageous that several items have to be plugged into one another, which involves a complex assembly. In addition, the operational safety of this relay is impaired because the individual insulating pins can get out of engagement during operation and are then loose in the housing.

The innovation is based on the task of developing the known relay so that it is easy to assemble and great operational reliability is achieved.

To solve this problem, the innovation is characterized in that the actuating element as a backdrop is formed, which is guided in lateral slots of a cross member connecting the blocks.

This ensures perfect guidance of the actuation

element created so that a safe operation both contact spring sets are reached.

It is preferred that the relay be housed in a dustproof housing to give, which consists of a front and rear housing half, and can be plugged into one another that it holds together without additional fasteners. The relay itself is also located in these two halves of the housing held without additional fasteners.

In a further development of the subject of the innovation are the soldering lugs for connecting the contact threads and the winding according to the wiring diagram on one side of the housing. According to a different wiring scheme they are led out on both sides of the housing .

The advantages of the innovation are in particular that the nesting of the spring sets and a particularly clear arrangement of the soldering lugs is achieved. These two properties, so flat design and especially clearer

Wiring plan, justify the designation -Ii of the relay according to the innovation as a "card relay",

J The actuation of the interlocking guides against

^! standing spring sets by the anchor over

the backdrop offers the main advantage that the se backdrop is designed to be very robust and particularly safe can be stored, so that a precise contact is guaranteed.

An example of the innovation can be found in Drawing shown:

The plug 1 of the renewal according to the card relay carries the bobbin 2. The one applied to it

Coil winding 3 u ~ "."; N soft non-magnetic core 4. This is with the. Jcrh j in magnetic Koiita] " ^J The armature 6, designed as a hinged armature, is tiltable on the yoke 5 in tilting bearings 7, yoke 7 träcjr dxe both Desire . 3, which are layered from parts of insulating material and wear the contact springs with their support springs. They are held together by the traverse 9 and the screws Io.

The armature 6 actuates a link 11 which is guided in lateral slots in the cross member 9. This setting actuates the two sets of springs, which are nested inside one another . The left bracket carries the front spring set 12, the right 3ock the rear spring set 13.

The relay is surrounded by a housing which consists of a front housing half 14 and a rear housing half 15 . The rear housing half 15 contains recesses through which the soldering lugs 16 of the front set of springs and the soldering lugs 17 of the rear set of springs protrude, as well as the soldering lugs 18 to which the winding is connected. The arrangement of the soldering lugs 16, 17 and 18 is shown schematically in FIG.

It is achieved by layering the brackets 8 accordingly and can be varied. In principle , it is also possible to have the soldering lugs 16 and 17 on opposite sides

To leak sides of the housing. Of course, the soldering lugs can also be designed as connector pins will.
