Description

Jan. 7, 1958 M. J. MATTHEYsEs RECTIFIER STACK Filed July 1. 1954 INVENTOR MACL MA/EYSES BY 030% ATTORNEY United States Patent O RECTIFIER STACK Marcel Jack Mattheyses, Ridgewood, N. J., assignor to International Telephone and Telegraph Corporation, New York, N. Y., a corporation of Maryland Application July 1, 1954, Serial No. 440,763
Claims. (Cl. 317-234) This invention relates generally to dry disc rectifier assemblies and particularly to an assembly which is adapted to be plugged into a standard type of receptacle to simultaneously provide electrical connections and physical support.
In prior art rectier stack assemblies external connections are made by soldering to the electrical connectors provided thereon and a special stud is provided for mounting the rectifier assembly.
An object of the present invention is the provision of a simplified rectifier stack structure which makes its electrical connections by being plugged into a standard socket and is supported thereby, thus requiring no special mounting stud and also eliminating soldering.
The above-mentioned and other features and objects of this invention and the manner of attaining them will become more apparent and the invention itself will be best understood, by reference to the following description of an embodiment of the invention taken in conjunction with the accompanying drawing in which Fig. 1 is a view in elevation and section of a rectifier stack and Fig. 2 is a schematic showing of the receptacle and one form of circuit connections therefor.
Referring now to the drawing, the rectifier stack 1 is comprised of a plurality of centrally perforated rectifier discs 2, mounted on an insulating tubing 3 through the center of which is inserted a threaded metallic rod 4. Metallic spacing washers 5 are interposed between adjacent discs and serve as the electrical connection between adjacent discs. On the outside of the end discs there are provided metallic washers 6 and 7. On the outside of metallic washer 7 is an annular metal ring 8 from which there extends, at right angles thereto, a terminal lug or contact prong 9, the contact prong 9 being thus electrically connected to one side of the stack. An insulating washer 10 insulates a metal terminal cap 11 which is provided at the end of rod 4 and from which there extends at right angles thereto a second terminal prong 12 parallel to prong 9. The prong 12 is electrically connected to the other side of the stack through the rod 4 and a threaded metallic nut 13 which presses against metallic washer 6. The nut 13 tightens on the rod 4 and holds the entire assembly together.
It is thus seen that a very simple assembly is thereby provided. The assembly may be plugged into a standard wall socket, preferably a polarized socket to prevent reversal of the connections, such as indicated at 14 and the electrical connections made to said socket. A typical circuit for providing a half wave rectified output from a source 1S is indicated with one side of the source being connected to one of the contacts 16 of socket 14, the other contact 17 being connected to the rectied output terminal 18. The opposite side of source 4 is connected 2,819,434 Patented Jan. 7, 1958 ICC to an output terminal 19. The usual by-pass condenser 20 can be connected from contact 17 across to the other side of the A. C. power source or to terminal 19. In the example of the polarized socket shown, the width of the contact 16 is at right angles to the width of the Contact 17 and correspondingly prong 9 is twisted so that its width extends at right angles to the direction of the width of prong 12.
While I have described above the principles of my invention in connection with specific apparatus, it is to be clearly understood that this description is made only by way of example and not as a limitation to the scope of my invention as set forth in the objects thereof and in the accompanying claims.
I claim:
l. A dry disc rectifier assembly comprising a stack of rectifier discs and metal washers each having a central opening therein, a metallic rod making electrical contact with one end of said stack and extending through the central openings towards the other end of said stack characterized by two contact prongs adjacent said other end of said stack forming a connector plug for insertion in a contact-making receptacle, one of said prongs being electrically connected to said stack at said other end thereof and the other of said prongs being connected to said rod at the end thereof adjacent said other end of the stack.
2. A dry disc rectier assembly comprising a central metallic rod having a head at one end, a nut threaded on the other end of said rod, an insulating sleeve on said rod between the head and nut, a plurality of dry rectifier discs having central openings and metal washers, strung on said sleeve to form a rectifier stack, said nut bearing against one end of the stack and making electrical contact therewith, said head bearing against the other end of the stack, an insulator electrically separating said head from said other end of the stack, a contact plate mounted on said sleeve making contact with said other end of said stack and two contact members arranged in the form of a plug-in connector for insertion in a contact-making receptacle, one of said contact members extending from said contact plate and the other contact member extending from said head.
3. A dry disc rectifier according to claim 2 wherein the contact member extending from said contact plate is integral therewith.
4. A dry disc rectifier according to claim 2 wherein the contact member extending from said head is integral therewith, said head being integral with the central rod.
5. A dry `disc rectifier assembly comprising a stack of rectifier discs and metal washers each having a central opening therein, a conductive rod making electrical contact with one end of said stack and extending through the central openings towards the other end of said stack characterized by two contact members arranged in the form of a plug-in connector for insertion in a contactmaking receptacle, one of said contact members connected with said other end of said stack, and the other of said contact members being connected to the end of said rod adjacent said other end of the stack.
