Application January 11, 1939, Serial No. 250,350
3Claims.
This invention relates to a plug connector, and particularly to a plug connector for connecting the actuator disclosed in my prior application Serial Number 754,812 filed November 26, 1934, for Dry shaving device and the actuator shown in my copending application Serial Number 250,349 led of even date herewith for Actuator with an alternating electric current supply.
This application is a continuation in part of said prior application Serial Number '154,812 noted, which issued February 7, 1939 as Patent No. 2,146,643.
It is an object of the invention to provide an improved plug connector which will contain therein the rectifying elements used with this type of actuator, and will properly connect the coils Vof the actuator with the A. C. supply by merely plugging the connector into the standard outlet receptacle or similar outlet or connector -in the usual house wiring system.
With the foregoing and other objects in view I have devised a construction as illustrated in the accompanying drawing forming a. part of this specification. It is, however, to be understood that I am not limited to the specic details shown but various changes and modications may be employed within the scope of the invention. u

CTI
of plates of magnetic material such as soft iron placed side by side to form a core or poles of the desired thickness and prevent heating. This core has three magnetic poles or legs, the two outer poles 2 and 3 and the center leg or pole 4. 'I'he windings for magnetizing the poles are preferably mounted on the outer legs 2 and 3 although they may be on the center leg if desired. Various arrangements of these windings may be usedseveral examples being shown in the copending applications mentioned. Only one example is shown in this application to illustrate the use of the improved plug connector involved. At the free ends of these poles is an oscillating armature 5 of magnetic material which bridges the spaces between the poles and is spaced a short distance from the ends thereof so as to be free to oscillate back and forth. It will, of course, be understood that this armature is mounted on a suitable support to permit this movement and is also connected to the element to be operated, such for example as the movable cutter of a dry shaving device, which are not shown in this case as they form no part of this invention.
It will of course be understood that the poles 2, 3 and 4 are so magnetized as to reciprocate l the armature 5 back andforth as indicated by the arrow 6. In the arrangementshown there- `is af pair of-alternating current working coils '1 andl 8 on each. legland 3 and connected in series by a lead 9. Coil'l is connected by a lead I0 with one side of a source of alternating current II. Mounted onthe legs 2 and 3 are also y' two sets of direct current exciter coils I2 andv I3 and I4 and I5, the coils I2 and I3 being connected in series by lead I6 and the coils I4 and I5 being connected inseries by lead I'I. The opposite ends of the coils I3 and I5 are connected by lead I8 to the alternating current coil 8 while the other end of the coil I2 is connected by a lead I3 with the outlet of the rectiiier 20. The
other end of coil I4 is connected by lead 2I tol The inlet of the inlet of a second rectier 22. the rectiiier 20`and the outlet from the rectier 22 are connected to the other side 23 of the source of alternating current II. It will be seen that the coils 'I and 8 are wound in the same sense while coils I2 and I3 are wound in the opposite sense and coils I4 and I5 are wound in the opposite sense. If now we assume that dur- Referring first to Fig. 10 the actuator shown ing one half the alternating current cycle current .enters through the lead Il) it will pass through the coils 'l and 8, lead I8, coils I5 and I4 and through rectifier 22 to the other side of the alternating current supply. Thus if the pole 2 is south, pole 3 is also south and center pole 4 is north. However, as the coil I5 is wound in the opposite sense to coil 8 it will tend to suppress the effect of coil 8 or cancel it out, while as coil I4 is wound in the same sense as coil 1 its eifect will'be added to that of coil 1 and the magnetization of the leg 2 will be increased, while the magnetization of the leg or pole 3 will be decreased or cancelled, and there will be a strong force tending to pull the armature to the left or toward the pole 2. During the other half of the cycle current enters through the lead 23, passes through the rectilier 20 to the coils I2 and I3 by lead I8 to coils I and 1 and then by lead III to the other side of the A. C. supply Il. At this time as the coils I3 and l are wound in the same sense they will assist each other and their eifect will be added up on the pole 3. while on the other hand the coil I2 is wound in the opposite sense to coil 'I and therefore they will oppose each other thus reducing the magnetization of the pole 2 to practically zero. 'I'his will cause heavy pull on the amature 5 to the right or toward the pole 3. Thus the two poles 2 and 3 will be alternately magnetized to the same extent by the combination of an A. C. and D. C. coil wound in the same sense while the magnetization of the other pole is reduced to a minimum by operation of an A. C. and D. C.' coil acting in opposition to each other. Thus the maximum pull is imparted to the armature 5 alternately in opposite directions reciprocating this armature back and forth in synchronism with the A. C. supply.
I have devised an improved, simple and effective means for mounting the rectiiiers 2II and 22 and properly connecting them with the respective coils and also connecting them with the source of A. C. supply by merely plugging into an outlet or similar connection in a house wiring system In this arrangement the retifiers are mounted in an attachment plug cap or plug connector comprising a casing 24 of insulating material made in two sections 25 and 26 connected when assembled by any suitable means, such as transverse rivets or screws 21. 'I'he two rectiiiers 20 and 22 are preferably formed by a rectox assembly comprising a suitable number of copper plates side by side in contact and having on one surface a coating of copper oxide which, as is well known in the rectox elements, permits electric current to flow in one direction but prevents it flowing in the opposite direction, thus cutting out one half of the cycle of alternating current. However, in the present case I divide this rectifier assembly thus making in eiect two rectiflers and therefore utilize the full alternating current.
The rectier assembly comprises a series of copper plates 28 having on one side the cupric oxide coating 29. Intermediate this series of plates is placed a conductor plate 30 having extending frorn one edge thereof a blade contact 3l which is offset at 32 and projects from the casing. On the opposite sides of the plates 23 from the plate 30 is a plate 33 connected to a lead corresponding to the lead I3 and carried through a cable 34 to proper coil of the actuator. On the other side of the other half of the rectox plates is a plate 35 connected to the: lead 2I corresponding to lead 2| in Fig, 10. There is also provided projecting from the casing a second contact blade 36 forming a part of the plate 31 which is separated from the plate 33 by an insulating plate 38. This plate 31 has an extending lug 33 to which the lead III of Fig. 10 is connected, these leads In, I3 and 2l being connected to their respective plates by solder or other suitable means. Plate 31 is preferably somewhat dished as shown in Figs. 1 and 7 so that when the elements are assembled on the cross bolt 40 this plate will yield or flatten as the elements of the rectier heat up under their rectifying action and thus expand. This spring action of the plate 31 maintains the parts in proper contact but also permits the necessary expansion under heating of the elements. The various plates are insulated from the bolt I0 by an insulating sleeve 4I. Plate 35 is also insulated from the head o! the bolt by an insulating plate 42, and the plate 31 is insulated from the other head or nut of the bolt by an insulating plate 43.
By this arrangement the rectiflers are mounted as a unit assembly in the plug-in connection for plugging into the usual outlet of the house wiring system and the leads I 0, I3 and 2l are connected to the proper coils in the actuator. These leads may be connected directly to the coils or through a simple detachable plug involving contact sleeves to which the leads are connected adapted to slide over thin contacts connected with the coils of the actuator as shown in the application mentioned as being led of even date: herewith. Therefore in using the actuator all th'e operator has to do is to plug this connector into any standard outlet or connector.
Having thus set forth the nature of my invention, what I claim is:
1. A plug connector comprising a casing, a pair of contact blades projecting from the casing for insertion in an outlet receptacle, a pair of rectiers in the casing and arranged with one of said blades connected with the outlet side of one rectifier and the inlet side of the other rectifier, and three leads extending from said casing, one of said leads being connected to the inlet side of the rst rectifier, another of said leads being connected to the outlet side of the second rectifier and the third lead being connected to the other blade contact.
2. A plug connector comprising a casing, a pair of contact'blades projecting from the casing for insertion in an outlet receptacle, two sets 0f rectier plates in said casing, one of said blades being located between the two sets of said rectier plates and connected with the outlet side of one set and the inlet side of the other set, and leads from the outer sides of said rectier sets and from the other contact blade respectively extending from the casing for connection to a device to be Operated.
3. A plug connector comprising a casing, a
central plate, two sets of rectifier plates on opposite sides of the central plate and in contact therewith, a second plate of resilient metal at the other side of one set and being laterally dished, a bolt passing through the plates and clamping them together, said dished plate being adapted to yield to permit expansion of the plates, a pair of contacts projecting from the casing for insertion in an outlet receptacle and connected respectively with the central and second plate, and leads from the casing connected respectively with the second plate and the outer sides of the two sets of plates.
