Description
Patented July 26, 1932 UNITED STATES WILLIAM o. nncx, or RIDGEFIELD, NEW .Tmtsiii, rd ts -1L na'romns, INCORPORATED, on NEW xongiitz; n oonrona'rrouon New. onx;
Application filed September 6, 19 29; 'Sei'iaIfNo. "a d This invention relates to electric test connecters and its object is to provide a connecter of this type which may be connected to telephone apparatus, such as relay springs, in
a convenient and positive manner and which.
will connect to a spring of a spring pile-up where a relatively small space is present without contacting with adjacent springs.
The test connecter of this invention comprises a flat blade, preferably of tempered steel slotted at one end to provide jaw members, the end opposite the jaws preferably terminating in the form of a finger key. The slot in the blade is extended backward into apertures which are engaged by pins crossing through a shaft in the groove of which the blade is mounted. One of these pins serves as a pivot for the body portion of the blade and the other for retaining one of the jaws 1Q against movement upon pressure exerted on the key, this pressure being effective to flex the body portion of the blade and thereby to. cause the. operation of the free jaw. The resiliency of the body portion is efiective to return the operated jaw toward the other jaw upon the release of the key to grip the spring to be tested. A sleeve of insulating material is mounted on the shaft or holder for electrically insulating the conductor from parts adjacent the terminal and the contact spring under test.
Referring to the drawing: Fig. 1 is an end view of the connecter; Fig. 2 is a side view of the connecter with portions cut away; 7
Fig. 3 is a view of the connecter showing a number of parts in section and the jaws of the connecter closed; and
Fig. 4 is a View of the connecter showing the housing in section and the jaws of the connecter in the open position.
Throughout the several figures, 10 represents a shaft having a longitudinally disposed oove 11. This shaft has at one end a reuced portion 12 shown in Figs. 2, 3 and 4 provided for connecting this end of the connecter with the conductor cord of the testing apparatus with which it may be used. In the groove 11 is mounted a connecter blade 13 which is retained in position therein by i..iv,...
. ins 1 eand'i15. .Theconne'cter blade' 7 provided at one-end withkapairof j awrmembers 16 and 17fwhichare. formed by thecutting of .a longitudinallydisposed slot 18 This slot extends .into an aperture 19'which ishobliquely disposed with respect to theloni gitlidinal axis of the connecter bladel13 and extends at a suitable distance from ..the-.-.outer edge of the blade 13 for: controlling the elasticity of thisblade andthe'rebfy the gripping pressure of the j aws on the" spring. :-to which the connecter is attached. Theend of blade l3 oppositeithe jawsl6 and 17 isbent at right tangles and onit. is mounted a key 20;:-
Th'e'. shaft 10. is: electrically insulated by means of a..-tubular.hoiising 21 which is held in position thereon by a pin 22' ln operation when a pressure is applied on the key 20, for movingit from normal posi-fl tion, shown in Fig. 3 to the position shown mits the movement of jaw 16 bodily with the connecter blade 13. Upon release of the button 20, the jaw 16 is returned to normal closed position through the medium of the tension of the connecter blade for gripping the springji to be tested.
It is understood that the device of this invention could also be used for other purposes than establishing electrical connections and that minor changes could be made'to suit particular requirements without departing from the scope of the appended claims.
What is claimed is 1. An electrical connecter comprising a slotted shaft, an insulating shell mounted thereon, a flat blade fitting the slot of said shaft and having a key at one end and a pair of normally closed jaw members at the other.
end, and means on said shaft whereby the movement of the key is effective to flex said blade to open said jaws.
2. An electrical connecter comprising a holder, a flat steel blade mounted in said holder and having a key at one end and a pair of jaws extending from the other end, a pivot for said steel blade mounted in said holder,
and means in said holder for holding one of said jaws in position in the holder during the flexing of saldsteel blade for operating the other jaw, the resiliency of said steel blade being .efl'ective to return the operated jaw to I closed position upon the release of said key.
3. A testing device comprising a flat steel blade having a slot in its front end extending backwardly into anaperture in the blade, a
key on the other end of said blade,'a holder in which said blade is positioned, said holder. 1 v .1 having a pair of pins projecting through said slot and aperture, one serving as a pivot for said blade when pressure is applied to the key W i and the other holding one oflthe jawsfrom movement in responseto the pressure, the resiliency of the blade returning the moved jaw to normal upon release ofpressure to cause the-jaws to grip an object.
. 4:. A-tool comprising a substantially oblong r shaped blade having a pair of normally closed jaws'formedby a slit in'one end thereof, a V
- support for said blade, a stop for one of said aws mounted on said support,'and means at the other end of said blade for causing pressure to be applied .to said blade tO'flBX it for causing the operation of the other jaw.
In witness whereof, I hereunto subscribe my name this 29th day of August, 1929.
