Dec. 24, 1963 Y. M. HOAG CONNECTING DEVICE Filed Dec. 30, 1960 INVENTOR YATES M. HOAG,
BY M (1 52!",
HIS ATTORNEY.
United States Patent 3,115,381 CUIWEC'HNG DEVICE Yates M. Hoag, Utica, NY, assignor to General Electric Company, a corporation of New York Filed Dec. 3t), ism, filer. No. 79,917 8 Claims. (ill. 3353-217) This invention relates to connecting devices, and more particularly to connector terminal devices for connecting electnical wiring.
There are various known types of connector terminals, such as screw types and spring or clip types. There has been a need for a new and improved connector terminal for use in electronic constructional kits, where the main requirements for such a connector terminal are low cost, simplicity, manipulability, and reliability.
An object of the invention is to provide a connecting device which is simple, reliable, easily manipulated, and low in cost.
Another object is to provide a connecting device which can easily and quickly be manipulated by youngsters.
A further object is to provide an improved connecting device for use in electronic constructional kits.
A still further object is to provide a connecting device which can be attached to a mounting board without the use of tools.
Still other objects will be apparent from the following description and claims, and from the accompanying drawing in which:
FIG. :1 is a front view of a preferred embodiment of the connecting device in accordance with the invention, showing the two parts thereof in partly assembled condition on a mounting board,
FIG. 2 is a front view of the connecting device in assembled condition,
FIG. 3 is a side view of the device of FIG. 2,
FIG. 4 is a top view of the device of FIG. 3,
FIGS. 5 and 6 illustrate how electrical connecting wires are inserted in and attached to the connecting device,
FIG. 7 is a side view of an alternative embodiment of the invention,
FIG. 8 is a front view of a further embodiment of the invention,
FIG. 9 is a top view of the embodiment shown in FIG. 8, and
HG. 10 is a front view of another embodiment of the invention.
The connecting device of the invention comprises, basically, a compressible helical spring adapted to be mounted onto a mounting board or chassis, and a loopshaped post member arranged inside the helical spring and adapted to receive an electrical connector wire when the helical spring is compressed.
Now referring to the preferred embodiment of the invention illustrated in FIGS. 1 through 6 of the drawing, a compressible helical spiing 11, wound from resilient spring wire, is provided with a neck 12 of reduced diameter at the lower end thereof, the turns of the spring at the neck 12 being closely spaced, Whereas the turns of the remaining portion of the spring 11 are spaced apart so that the spring 11 may be compressed when pressure is applied thereto in an axial direction. The neck portion 12 of the spring 11 is adapted to fit snugly into an opening 13 through a mounting board 14, The mounting board '14 may be a board or chassis made of insulative material, such as fiber board or plastic, which serves as the mounting board or chassis of an electronic constructional kit or other suitable device.
A loop-shaped post member 16, made from resilient spring wire or other suitable material, has an apex portion 17, and outwardly extending shoulders 18 and 19 on the sides 21 and 22 thereof. The end regions of the sides 21 and 22 remote from the apex 17 are respectively provided with legs 23 and 24 extending transversely with respect to the sides 21 and 22, these legs 23 and 24- being generally parallel with respect to each other.
To assemble the connecting device of FIGS. 1 through 6, the neck portion of the helical coil 11 is inserted into the opening 13 of a mounting board 14, this mounting board 14 being illustrated in cross-section to better reveal the opening 13 therein. Preferably, the neck 12 fits snugly within the opening 13. This snug fit is easily pro vided due to the resilient nature of the turns of the spring comprising the neck portion 12. If desired, the opening 13 may be provided with threads, so that the neck portion 12 of the spring may be threaded therein. The length of the neck portion 12 is preferably, though not necessarily, the same as the thickness of the mounting board 14.
The loop-shaped post member 16 is then inserted, as indicated by the arrow 26, into the spring 11 through the neck 12 thereof, to the position shown in FIGS. 2, 3 and 4. In this assembled position, the shoulders 18 and 19 of the loop-shaped member to engage and lock within the helical spring ill at a position just above the neck pontion 12, the resiliency of the loop member 16 maintaining the shoulders lo and 19 in this locking position. in this assembled position, the legs 23 and 24 of the loop-shaped post member 16 engage against the underside of the mounting board 14 and are so oriented, as shown, to stabilize the osition of the post member 16.
The lower-most portions of the member 1a are curved away from the mounting board 14, as indicated at 27 and 28, so that only the outer extremities 3i and 32 of the legs 23 and 24 will engage against the underside of the mounting board 14-, thereby insuring maximum vertical stability of the loop-shaped post member 16.
The connecting device functions as follows. To connect an electrical wire to the device, the top of the helical spring 11 is manually pressed downwardly to the position shown in FIG. 5, thereby exposing the apex 17 of the post 16 so that the bared end 36 of an electrical connector wire may be inserted into and through the loop formed by the apex 17, whereupon the spring 1'1 is released and urges upwardly against the wire 36, as shown in FlG. 6, thereby holding the wire 36 securely and making a good electrical connection to the wire and to other wires 3'? which also are inserted through the loop of the apex 1? of the post member 16.
In many applications, the desideratum will be to electrically connect together a plurality of hookup wires as, 37 by means of the connecting device, in which event it is not necessary that the connecting device itself be electrically conductive. For such applications, either or both of the helical spring 11 and the loop-shaped post to may be made of non-conductive material, such as resilient plastic The spring 11 is readily depressed manually, by pressing downwardly thereon with one or two fingers or with a thumb and finger, or with a screwdriver blade or other suitable object.
In the embodiment of FIG. 7, the helical spring 1i and loop-shaped member 16 are formed from a single piece of wire, as shown, the intermediate portion of the wire be tween the spring H and loop member in being curved as indicated at ill in a manner to fit snugly into an opening 13 in a mounting board 14. In this embodiment, the opening 13 may be in the shape of a narrow slot, thus insuring that the bottom of the helical spring Ill will seat against the board 14 and remain securley in position when the spring 11 is pressed downwardly from the top in order to insert wires under the apex 1'7 of the loop member "16.
In many situations, the plug-in portion 41 can be made to fit in the opening 13 sufiiciently tightly so that the connector terminal will remain in place during normal use. The securing of the coupling device to the mounting board 14 may be enhanced by providing outwardly protruding shoulders 42 on the curved portion 41, whereby these shoulders 42 can pass through the opening 13 and will expand slightly outwardly just below the opening 13 when the connecting device is in place. A further or alternative means of more tightly securing the coupling device to the mounting board 14, is to provide a pin or wire 43 extending through the portion 41 just below the mounting board 14.
In the embodiment shown in FIGS. 8 and 9, the helical spring 11 and loop member 16 are the same as in the embodiment of FIG. 7. The connector loop 41, however, extends laterally of the axis of the spring 1.1, and is attached to the mounting board 14 by means of a screw 44 or rivet attached to the mounting board 14 and extending through the laterally positioned loop 41.
FIG. illustrates a modification of the connection device, in which the device is attached to a mounting board 14 by means of a plug-in loop 41 extending into an opening 13, similar to the embodiment of FIG. 7. In FIG. 10, the wire-receiving loop 16 is inverted from the other embodiments shown and the helical spring 11 is provided with a lower region 45 in which the turns are widely spaced apart. In operation, when the spring 11 is pressed downwardly, the apex 17 of the loop becomes exposed in the region 46, whereupon connector wires may be inserted through the apex 17 of the loop. Upon release of the spring 11, the connector wire will be tightly held against a turn 4''? at the upper part of the region as.
