2 Claims. (Cl. 339-184) This invention pertains to novel and improved means for electrically connecting an instrument through its casing with an outside cable. More particularly, the purpose of the invention is to provide a plug that will permit such connection of instrument and cable in a simple manner without taking up too much space. A further purpose of the invention is to provide a connecting plug for an instrument and its outside cable, that will permit removal of either the cable, or the casing of the instrument without disturbing the terminal wiring of the instrument.
A still further object of the invention is to provide a novel type instrument-cable connecting plug having conducting pins projecting through opposite faces, whereby the plug may connect at one end with the wiring of the instrument and at the other end with an outside cable.
The invention further lies in the particular construction of the plug as well as in its various component parts and in their general arrangement to produce the results intended.
The foregoing and other objects and advantages of this invention will appear more fully hereinafter from a consideration of the detailed description which follows, taken together with the accompanying drawing wherein an embodiment of the invention is illustrated. It is to be expressly understood, however, that the drawing is for purposes of illustration and description and is not to be construed as defining the limits of the invention.
The drawing is a cross sectional view illustrating the invention.
In describing the invention in detail, reference is now directed to the drawing wherein there is disclosed a portion of the supporting framework 1 of an electrical instrument. The instrument is of a type having an electrical terminal 2 that must be connected, through a wall of the casing 4 in which the instrument is housed, to an outside cable 5.
It is intended that the terminal 2 be connectable through the wall of casing 4 with the outside cable 5 by a single plug, whereby the casing may be removed from the instrument without disturbing the terminal wiring of the latter. To this end, a receptacle 6 is mounted fast to the instrument framework 1 over an opening 7. The terminal 2 is wired to the inner end of a pin socket 8. This socket opens through to the outside of the receptacle. Secured, as by a flange 10 and solder, in an opening through the casing wall 3 is a plug member 11. Sealed, as by a glass insulator 12, in the body of the plug is an electrical conducting pin member 14. The latter extends transversely through the body of the plug and projects through opposite faces thereof. An end of the pin projects into the interior of the case 4; while the other end 16 projects from the outside of the case.
The pin socket 8 of the instrument receptacle is suited to receive the projecting pin end 15, when casing 4 is assembled over the instrument framework 1. It is clear, by this arrangement that the casing of the instrument may be readily removed from the latter, or assembled thereto without disturbing the terminal wiring of the instrument.

The outside cable 5 carries a receptacle end piece 17 having a pin socket 18 to the inner end of which is wired a terminal end 19 of the cable. This pin socket is suited to receive the outer projecting pin end 16 of the plug, whereby a conducting line is established from the terminal wire 2 of the instrument through the casing to the related terminal wire 19 of the cable.
While but one pin member 14 has been shown in the body of plug 11, and but one terminal in each of the receptacles 6 and ,17, it is understood, and further illustration appears unnecessary to show that the plug may contain a plurality of pins, and the receptacles complementary pin sockets, 8 and 18, each pin member serving to associate a particular terminal wire socket 8 of the instrument with a particular terminal wire socket 18 of the cable.
Polarizing elements are provided to facilitate assembly of the plug with the associated receptacle. To this end, the instrument receptacle 6 is mounted to the framework of the'instrument by a polarizing pin 20 and a polarizing guide 21, screw ends 22 of each of which are threaded into the framework of the instrument. Similar screw ends 22 of a pin 20' and a guide 21 hold the receptacle 17 fast to a thickened body support 23 of the cable. A combined polarizing pin and guide member 24 secured transversely of the body of plug member 11, as by solder, includes a projecting guide piece 25 which is suited to receive the complementary polarizing pin 20 of receptacle 6, and it includes a projecting pin piece 26 which is receivable in the complementary polarizing guide 21' of receptacle 17. A second combined polarizing pin and guide member 24' is provided in the body of the plug in a position reverse to the member 24, of which the projecting pin piece 26' is receivable in the complementary guide 21 of the instrument receptacle, and the projecting guide piece 25' receives the complementary polarizing pin 20' of the cable receptacle.
By this polarizing arrangement it is clear that each pin member 14 that may be contained in plug 11 will be received into its proper socket, both in the instrument at one end and in the cable at the other end. Moreover, as shown in the drawing, in aligning the end portions 15 and 16 of the pin member 14 with the complementary pin sockets 8 and 18,. the combined polarizing guide and pin means 25-26 and 25'26' carried by the body of the plug 11 provide a close frictional fit respectively with the pin and guide members 20-21 carried by the receptacles 6 and 17 and the pin and guide members 20'--21 carried by the receptacles 17 and 6 so as to releasably secure the instrument receptacle 6 to one face of the plug 11 and the cable receptacle 17 to the opposite face of the plug 11 and thereby permit independent engagement and disengagement of said receptacles 6 and 17 with regard to the plug 11 and removal of the casing 4 from the instrument 1 without disturbing the terminal wiring 2 of the instrument.
While an embodiment of the invention has been illustrated and described in detail, it is to be expressly understood that the invention is not limited thereto. Various changes can be made in the design and arrangement of the parts without departing from the spirit and scope of the invention, as the same will now be understood by those skilled in the art; and it is our intent, therefore, to claim the invention not only in the form shown and described, but also in all such forms and modifications as can reasonably be construed to be within the spirit of the invention and the scope of the appended claims.
What is claimed is:
1. In combination an instrument having an electrical receptacle including a first pin socket to which an electrical terminal wire of the instrument is secured, an electrical cable positoined outside of the instrument and having an electrical receptacle including a second pin socket to which an electrical terminal Wire of the cable is secured, a casing in which the instrument is housed including an end opening, an electrical plug secured in said endopening, the electrical .plug having a conducting pin fiXed't'r'ansversely-in abodyportion thereof and char- "acterized by first and second endsportions thereof project- 'ing'fr'om 'opposite'faces of the body portion, the first end portionjprfojecting from one face of the body portion .an'dbein'g receivable in'the'first pin socket of the instrument receptacle, and the second end portion projecting from the opposite'face of the body portion and being receivable in the second pin socket of the receptacle of thecable, guide andipin members carried by said recept'a'cles,.pin and guide means carried by the electrical plug and cooperating with the guide and pin members carried 're'lea'sably secure the instrument receptacle housed within thecasing to one face ofthe body of the electrical plug and the receptacle of the cable outside of said casing to "the opposite face of the electrical body portion of the 4 plug and thereby permit independent engagement and disengagement of said receptacles, with regard to said electrical plug and removalot the casing from the instrument without disturbing the terminal wiring of the instrument.
2. The combination defined by claim 1 in which said pin and guide means includes polarizing members secured transversely of the body portion of the electrical plug, each of said polarizing members having aprojecting pin piece and a projecting guide piece mounted at opposite ends thereof for cooperation respectively with the "guide and pin members carried by said receptacles.
