ELECTRICAL CONNECTION.
Application filed July 25, 1925. Serial No. 46,171.
My invention relates broadly to electromagnetic sound reproducers and more particularly to a construction of terminal block for electromagnetic sound reproducers.
6 One of the objects of my invention is to provide a construction of terminal block for electromagnetic sound reproducers, where connections from the exteriorof the casing of the sound reproducer may be snapped into mechanical and electrical engagement without the necessity of adjusting individual binding screws against each of the conductors which connect with the electromagnetic sound reproducer.
Another object of my invention is to provide a terminal block construction for electromagnetic sound reproducers which is particularly adapted for making positive connections between a plurality of conductors ill 2 leading to the electromagnetic sound reproducer and the windings of the sound.
reproducerby a resilient gripping action without the requirement of individual adiustment ofbinding screws heretofore re- 2 quired in the art.
. Still another object of my invention is to provide a. resilient grip terminal block for terminals leading from flexible conductors into the interior of ,an electromagnetic sound reproducer, wherethe 'tei'minals are positivelygripped by a single movement toward the electromagnetic sounii reproducers.
I have illustrated my invention with particular reference to telephone receivers but it will be understood that my invention is applicable to various constructions of electromagnetic sound reproducers, including loud speakers, table talkers and the like. In the application of my invention to telephone receivers a pair of resilient grips are provided for completing connections be tween the magnet windings interiorly of the electromagnetic sound reproducer and the conducting cords which lead to the sound reproducer. Intermediate the terminals thus provided, I provide a resilient grip sleeve which is arranged to cooperate with a terminal member connecting to an electrostatic shield surrounding the telephone conductors. The electrostatic shield is connected through the intermediate terminal with 1=the casing of the telephone receiver.
My invention will be more clearly understood by reference to the following specification and the accompanying drawings, in which:
Figure 1 is a plan view showing theinterior arrangement of a telephone receiver employing the terminal block of my invention; Fig. 2 is a side view showing a telephone receiver equipped with the terminal block of my invention, while the terminal block is indicated by dotted lines; Fig. 3 is a plan View of the terminal block with the resllient connecting members shown therein in dotted lines; Fig. 4 is a front view showing the construction of the terminal block of my i'nvention; Fig. 5 is a detailed view showingone of the cord terminals leading into the telephone receiver casing and gripped within one of the resilient contact members therein; Fig. 6 is a plan view of the intermediate terminal used for completing electrical connections between the electrostatic shield surrounding the telephone receiver cords and the casing of the telephone receiver; Fig. -7 is, a cross-sectional view through one of the telephone receiver cord terminals and the resilient grip sleeve by which the terminal is gripped within the terminal block. and the u wardly extending lug which makes connections with the mag-* net windings interiorly of the receiver; Fig. 8 is a cross-sectional view through the re silient grip sleeve and groundin collar in which the terminal of the e ectrostatic shield is enclosed; Fig. 9- shows front and side views of the lug-which surrounds the resilient grip sleeve connecting the telephone receiver cord terminals with the bobbins within the telephone receiver; Fig. 10 is a front and side view of the grounding collar which completes connections between the electrostatic shield and the casing of the telephone receivers; and Fig. 11 illustrates more particularly the construction of one'of the terminals which are provided on the ends of the conducting cords and the electrostatic shield.
position within the casing 1, by means of the kidney pieces 4 and 5 which extend over portions 8 and 9 of the terminal block. The terminal block 7 is constructed of substantially semi-circular portions of insulated .material 10 and 11, divided alon a horizontal axis 12 and secured togetherdiy means of binding screws 14 andl5. Each of the portions 10 and 11 contain cut away portions 16, 17, 18, 19, 20 and 21 which are brought adjacent to each other and form substantiallycylindrical bores extending into the terminal block. Positioned Within these bores I provide split resilient collar members 22, 23 and 24. The construction of collar members 22 and 24 is shown more particularly in Fig. 5. Each collar member consists of a cylindrical portion which is split longitudinally with the side edges-0f the collar member parallel with each other throughout their lcngthfas represented at 22. The collar member 22 is surrounded and gripped by a lug member 25, shown more particularly in Fig. 9. The lug member 25 consists of a sheet of material which is bent upon itself with its faces pressed into contact with each other along its portion 25 and bent into a substantially circular portion 25 which encloses and grips the collar member 22. The lug member 25 is open at point 25 to enable the resilient grip sleeve 22- to readily increase or decrease in its efiective diameter. The upstanding portion 25 serves as a connecting lug for the magnet windings of the telephone receiver. The
I have illustrated my invention in one of its preferred embodiments, but I desire that it be understood that other modifications may be made and that no limitations upon the invention are intended other than are imposed by the scope of the appended claims.
What I claim and desire to secure by Letters Patent of the United States is:
1. A terminal block, a plurality of resilient-slceVe-like contacts therein, said block and said contacts havin" aligned entrances located at. one side of said block to admit a plurality of terminal tips, each of said contacts, comprising a spilt cylindrical portion with an inwardly extending annular ridge adjacent one end thereof, and a collar memb'er extending around each of sald contacts and havlng extended portions asslng through said block to provide a ug by means of which an electrical conductor may be connected to the contacts, each of said tips comprising a cylindrical portion and a spherical head separated by a neck portion, said neck portion being arranged to be gripped by said annular rid e within said sleeve-like contacts when sai terminal tips are forced into said sleeve-like contacts.
2. A terminal block of insulating material, a pair of resilient sleeve-like contacts therein, a similar contact in said block parallel to and between said pair of contacts, a collar member ripping each of said pair of contacts and aving an extension thereon extending upwardly through said block to rovide a binding lug, and a collar memer gripping said intermediate contact and having an extension thereon extending downwardly through said block.
In testimony whereof I aflix my signature.
