WIRING PANEL. FOR ELECTRICAL APPARATUS.
\ Application filed September 9, 1927. Serial No. 218,384.
This invention relates to wiring panels for electrical apparatus and has particular reference to means for Wiring a radio set, although adaptable for use in connection with other forms of electrical apparatus.
One object of the invention is to provide means whereby. such electrical apparatus as above mentioned may be easily and quickly wired by an unskilled person, and Without the use of numerous or expensive tools. An-
other object is to provide such wiring means 'which will practically insure proper con-' nection of the various elements constituting the apparatus. r
A further object-of the invention is to provide wiring means of the class described which can be economically manufactured in a shop and sold as a unit to the builders of the apparatus for which the unit is intended.
is adaptable to practicall any desired form of electrical circuit, sue as,'for instance, .any of the present day radio circuits; to provide a wiringpanel which will be effective, as an incident to its wiring function, to support the devices which it connects; and to provide a structure of the class described which will be neat and compact and will enhance the appearance of a connected group of electrical devices by eliminating the usually numerous exposed wires extending in various directions and also by grouping silich devices according to a predetermined an. 1 It is also an object of the invention to provide an improved method'of making the wiring panel and in general to provide an improved device of the class described. Other objects and advantages of the invention will beunderstood by reference to the following specification and the accompanying drawings in which I have illustrated one form of the invention embodied in a radio receiving set, and in which drawings Figs. 1, 2 and 3 are plans, .respectively, of three layers of panel and wiring which are adapted to be assembled, by. being super three layers when assembled. 4 Figs. 5 and 6 are cross sect onsof a radio receiving set illustrating the method of 5 using the panel to connect a plurality of Stillfurther objects of the invention are to provide a wiring panel construction which Fig. 4 is a plan illustrating the unitary radio electrical devices into a radio receivlng circuit, these figures Including sections of the panel taken on the lines 5 5 and (ib',
respectively, of Fig. 4.
Referring to the draWings,.1 have indicated in Fig. 1' a panel-layer or sheet 10, preferably of a phenol condensation insulating material such as bakelite or other suitable insulating material. The material used is preferably such that it may be formed into pliable and semi-cured sheets which may subsequently be completely cured and hardened. The pliable or semi-cured sheet 10'is provided with one or more apertures or notches 11 for a purpose which will presently appear. One or more, conductor members 12 are disposed onf'the face of the layer 10 and arranged thereon. according to a predetermined plan. The conductors are cated at 13 and 14. The terminal portions 13 project into the apertures 11, and the terminalportions 14 project outwardly from the panel, preferably projecting from an edge thereof.
In Fig. 2, I have illustrated a panel orsheet 15' similar in size and form to the sheet 10. The sheet 15 is also referably apertured as at 16 in accordance with the arrangement of the apertures or notches 11in the sheet 10. One or more conductor members 17, similar in construction to the conductors 12, are disposed in the desired arrangement on the sheet 15 and are provided with terminal portions 18 projecting into the variousapertures and terminal portions 19 projecting outwardly from the edge of the sheet.
In Fig. 3, I have illustrated a third panelextending into the apertures 21 and terminal portions 24 extending outwardly from the edge of the sheet.
The wiring panel, accordmg to the presentinvention, is formed by superposing the sheet 1-5 and conductor members disposed thereon over the sheet 10 and its conductors, and then superposing the sheet 20 with its conductors over the sheet 15. It will be apparent that' the construction so far described consists of three separate, superposed layers of pliable or semi-cured insulating material, between thev adjacentfaces of which there are arranged sets of conductors disposed according to a predetermined plan. A fourth layer or sheet of insulating material 53 (Fig. 5) having apertures and notches similar to those in the other layers is superposed over the third sheet so as to cover the conductors thereon, and the four superposed sheets are then pressed together so as to firmly rip the conductors therebetween and to em ed the same in the adjacent sheets, after which the superposed sheets are completely cured so as to form a one-piece panel having a plurality of conductors embedded therein. This one-piece panel structure with conductors embedded therein is illustrated in 'sectionin Figs. 5 and 6, the planes in which the various sheets or layers are united being indicated by light lines 54 extending across the width of the panel. As
shown in Fig. 4, the pressed and cured panel structure results in a wiring unit having the desired terminals projecting outwardly from the edge thereof for receiving connections from batteries or other sources of electrical energy or other electrical devices. The panel of great importance'in connection with radio apparatus.
The arrangement of conductors and terminals disclosed in the present embodiment of the invention is for the radio circuit commercially known as thePfanstiehl circuit. The notch 25 indicated at the upper left hand corner of the panel is provided for the pur pose of permitting'connection and mounting of a suitable switch member 26, as shown in Fig. 5. As shown in this figure, the wiring panel designated 27 is fixedly mounted rela-' tive to a suitable front panel 28 by means of a plurality of mounting brackets 29. The
. switch 26 is of a type which is secured to the frontpanel 28 and is controlled by means of a knob 30. The terminals 31v and .32 of the switch member 26 are connected respectively to the source of electrical energy and'to the '.terminal 14 which is. a part of the conductor 12 of the first set or layer of conductors. Radio frequency coils, such as indicated at 33 -in Fig. 5, are connected by means of conductors 34, 34 to the proper terminals projecting into the apertures 35 of the panel 27.
, Suitable variable condensers, one of which,
is indicated at 36 in Fig. 5, may be mounted on the panel 27 by means of screws 37 or other suitable means, apertures 38 being provided in the panel for permitting the passage of the screw 37 theret-hrough, without contacting with any of the various conductors embedded in thepanel. Apertures 39 are also provided in the panel 27 for permitting the passage therethrough of the condenser operating shaft, one of which is indicated at 40 and which is connected to a dial 41 disposed in front of the panel 28.
Radio tube holders or sockets such as indicated at 42 may be connected, as-.clearly shown in Fig. 6, to the proper terminals projecting into the apertures 43 in the panel, and audio transformers such as indicated at 44 may be connected to the proper terminals projecting into the apertures 45. Apertures indicated at 46 and 47 serve to expose terminal portions for receiving condensers required by the radio circuit for which the present panel is arranged, and the notch indicated at 48 is provided for facilitating mounting of a jack 49 which is connected to terminals projecting into the said notch from the edge of the panel.
The construction of the panel is such that the terminal portions which project into the apertures and receive terminal portions of the various devices will be sufiiciently rigid to support the devices connected thereto in substantially fixed position relative to each other. If desired, suitable fixed resistances indicated at 50, 51 and 52 may be embedded in the panel between two of the layers and connecting certain of the conductors as required by the circuit for which thepanel is designed.
For other circuits requiring a lesser or greater number of conductors and terminals of the conductors as well as the number of layers of panel materialand number of layers or sets of conductors. For a simple cir- T cuit involving relatively few conductors, it
may be found practical to include all of the conductors between two sheets of insulating material, provisionbeing made for insulating conductors' which of necessity must cross one another. Such a provision might include, for example, a relatively thin flat piece of insulatiiig material positioned between the overlapping or crossing" parts of the conductors. For; more complicated circuits requiring a greaternumber of conductors, it is preferable to separate the conductors so that where one crosses another it is separated therefrom by a layer or sheet of the insulating panel material, and it. is obvious that as many layers as required may be eombinedto form a umtarv'wiring panel of the class described.
