Plug connection for an electromechanical time relay

The innovation relates to a plug connection for an electromechanical timers, in which all the components such as motor, magnetic coupling, Zeitablaufrad, adjusting knob and the like in cascading order centered about an axis, are arranged at the same time the adjustment and drive shaft.

Such a timing relay is already known (DT-PS 1 239 761).

especially advantageous in production »if all necessary structural parts are taken up by a common central axis, which is also the actuation axis represents. The number of individual parts and the production time can be reduced to a possible minimum. The individual components also include, for example, the mechanics of the time setting such as gears and timing elements any necessary gear and the like. The common arrangement of all components around the supporting axis facilitates but not only the assembly of the relay, but also the subsequent addition and completion of the same through any additional components that may be required, such as additional gears or switching cam disks. Also is through this type of construction has a particularly low level in the plane of the forehead j

surface of the relay is given because the j

i One behind the other on the common central axis in the generally available installation depth can be fully utilized.

Timing relays of the type of interest here are designed so that the required electrical connections are either via Terminal strips are made by screw connection or soldering or finally by a plug connection. The known plug connections used in this context consist of knife-like flat plug contacts, in accordance with the known terminal strips in rows and / or rows next to each other

Lie, Such Steekverb.U ^ ungen in the form of contact pins are located on the rear faceplate of the timing relay, they can be plugged into a plug-in console designed analogously to this, on which the relay is subsequently locked so that due to its own weight, it cannot unintentionally detach itself from the connector.

The known plug connections designed in this way need

due to the large number of connections required for a timing relay

This means that a large amount of space is required on its rear face and they can be inserted into the plug-in console tilt and, due to their flat design, also bend them if necessary.

This is where the present innovation comes in, which is based on the task of a plug connection for electromagnetic time relays of the type mentioned above to the effect that the inadequacies that have occurred so far are avoided can.

According to the innovation, the solution to this problem is given by that the rear faceplate of the timing relay is aligned with the imaginary axial extension of the supporting all components common axis lying per se known tube base carries, in which around a central guide pin at the same distance a plurality of contact pins is arranged.

The socket, which has been known in the tube industry for many decades, enables robust handling with the least possible Danger. The central guide pin, which is advantageously made of insulating material, around which the individual contact pins are arranged centrally, the timing relay leads neatly into the plug-in console when the plug-in connection is made and aligns the individual contact pins exactly in line with their socket parts in the plug-in bracket. The round shape of the Contact pins are the most mechanically stable option, so that the mechanical stress is minimal Pin diameters are sufficient, especially since it is known that the current values transmitted for a timing relay are not very large.

The aligned and thus central arrangement of the tubular base in its circular structure also avoids in optimal Wise constraining forces such as those caused by careless, for example, oblique insertion of the timing relay into the plug-in console can.

The accompanying drawing shows an exemplary embodiment of the plug connection arranged according to the innovation, which is a longitudinal section through an electromechanical Timing relay of the type mentioned and a top view of the plug-in console with which the rear end wall of the timing relay is brought into contact with the establishment of the plug connection, acts.

As can be seen in the sectional view, the timing relay is housed in a housing 13. The axis 8, designed as a supporting shaft, is sleek in the direction of the longitudinal axis of the housing 13 arranged in this and through the front Face of the relay passed through, where they are there how can be seen from the drawing, is stored. At the front end of the axis 8 there is a rotary knob 9, via which the area preselection can be made for different time ranges. Located below the transparent lens 12 a scale over which the return pointer 11 runs when the timing relay al: runs and is fixed to the timing element connected is. Below the rotary knob 9 there is a further rotary knob 10 that allows the time to be set within of the selected time range. The pointer 11 is fixed with the hollow shaft seated on the axis 8 a shift lever 6 verbunc? / in, the one not shown

actuated
KontaktyOind returns to the starting position via a return spring when the relay is de-energized.

The drive of the axis 8 takes place via the drive motor 1, the is advantageously a synchronous motor to which a gear is flanged, the side output pinion in the Teeth of a gear 2 meshes, which rotatably. with the one: Half 3 of the magnetic coupling 3,4,5 is connected. The second half 5 of the magnetic coupling is firmly fitted onto the hollow shaft, with which the shift lever 6 is rigidly connected. uit The magnetic coupling is actuated via the excitation coil :: -

The magnetic coupling can, again drive motor 1, which is at the bottom The end of the axis 8 is attached to the center of the axis 8 only because the two coupling halves 3.5 as Bushings are formed, which on the axis 8 in the illustrated Way are attached. The preselection of the time range via the rotary knob 9 and the time setting within a time range The rotary knob 10 takes place when the magnetic coupling 3, 4, 5 is de-energized, while when the coil 4 is energized, and thus When the coupling connection is closed, the movement of the drive motor 1 is transmitted to the gearshift lever 6 via the gearwheel 2 will. The coupling half 5 thus represents the actual timing element represent, so that with the most space-saving arrangement with a minimum of individual parts.

; The lower or rear face 14 of the timing relay is fixed connected to the housing 13 and carries a connector in the middle, which is designed as a tube socket 16, 17. The Röh » rensockel is composed of the contact pins 16, which are at the same distance on an imaginary circle, the The center of the center of the guide pin 17 is. which lies in the aligned extension of the axis 8. The number of Contact pins 16, which are round in cross section, correspond to the maximum

j required number of line connections to the time j

j lais. The guide, which is preferably made of insulating material

In the exemplary embodiment, the locking pin 17 carries a fixing lug 18 running in the axial direction along a circumferential surface, '

so that incorrect insertion of the timing relay into the plug-in console, which is shown in the drawing in plan view, is excluded. The contact pins 16 are through the rear Front plate 14 passed through and thus give the solder connections within the housing 13 of the timing relay at the same time 15 for the wiring of the timing relay.

The plug-in bracket shown in the accompanying drawing above the sectional view of the timing relay in a plan view corresponds to in their embodiment of the arrangement and dimensioning of the guide pin 17 and the contact pins 16 of the Tubular socket. The guide pin 17 with the fixing lug 18 fits into the bore 17 'with the recess 18 * of the plug-in bracket 19 and the contact pins 16 slide into the under spring pressure

Instead of the fixing lug 18 on the guide pin 17, it is also possible to use one of the contact pins 16 with an associated plug socket 16 * thicker in diameter than the remainder, so that this also prevents the wrong insertion of the Time relay in the plug-in console 19 is excluded.
