Jan. 24, 1956 G. J. GIEL ELECTRICAL CONNECTOR Filed Jan. 15, 1954 Geo/ye J 6/9] INV ENTOR.
A'ltorney Uaied S em n ELECTRICAL CONNECTOR GeorgeJ. Giel, .venic caun, rassignorl to Audio Products Corporation, ILos .Angel'es, Calif.,.a corporation .ot. Cah- 'fornia Application January- 15, 1954', Serial N 404,244 6. Claims. 01. 339-176) Thepi'es'ent invention relates generally-to electrical connectors, and is more specificallyyconcernedjwith a connector of the plug' and -sockefi type-by means of which one or apl'urality of'circuit componentdevices-maybe inserted into or removed froman 'e'lectri'c'circui't.
The-connector of the present invention has been found to be especially advantageous in 'connectionwith conductors or commonly designated patchcords"*by which electroniccircuits-may be interconnected for testing and oth'erpurpose's, where it is very-often desirablefto be able to insert coupling impedances -such'as capacitors, resistors, crystal diodes, andthe lik'e' intoalinebr'patch- 'c'ord 'connecting the'circu'its. V
"It is one object of the herein described invention to provide a connector of simple construction, which is so arranged that two patchcords, or'conductorsections may be mechanically interconnected, and "atthe same time make electrical connection with electric 'termin'ahstructuiesin the connector, these terminal structures being so arrangedthat circuit componentdevicesrnay b fbr'idging'ly connected between--the terminal 'structure s to' vary the-circuit-characteristics. I g
A further object is to "provide such "connector "in wliich the terminal structure is'so arrange'clthat it'willau'tomatically grip 'the terminal leads" of th'e' circuitco mponent when-inserted through openings of? the connector body.
,For accomplishing the above, the connector of the present invention in its broad concept provides a tubular body of insulating material which supports terminal structures at its ends, these terminal structures eachbeing provided with a contact portion ,for electrically 'connecting:with.an associated conductor-orgpatchcord: The terminal structure also incorporatesa -contacttwhichuwill automatically grip a. terminal of thetcircuit component 'tobe connected into the circuit, Whenithe contacti lead is :inserted through an opening in the body endwise'into itsrinterior. V
Further objects of the invention will be brought out in the following part ofthe specification, wherein detailed description is for the purpose of'fully disclosing the invention without placing. limitations thereon.
Referring to the accompanying drawings, which are for illustrative purposes only:
Fig. l is an exploded perspective view showing a connector embodying the features of the present invention, and the manner in which it is connected into a circuit and utilized for the connection of one or a plurality of circuit components into the circuit; I
Fig. 2 is an enlarged longitudinal section through the connector; and
Fig. 3 is a transverse section through the same, taken substantially on line 3-3 of Fig. 2.
Referring more specifically to the drawings, the connector is shown as comprising an elongate tubular wall 10 of suitable material, shown in this instance as insulation. This tubular wall forms the body of the connector and at its ends is internally threaded, as indicated 2,732,534 "Patented Jan. 24, 1956 at. 1 1, to receive in threaded relation thereto an end closure 12; in each'case;
Since 'the 'end closures are similarlyconstructed', it is 'be'lieved' 'that it. will'sutfice for descriptive purposes to describe the detailconstruction of one of these closures only. The closure is in the form of a plugwliiclris arranged to be screwed into an-end of-the connector body until==restrained-by an end abutment flange 13. Various materials-may be utilizedfor the construction or th'eend closure, nylon' havi'ng been'found'to be admirably suited 'for such 'purpose. As shown, the plug or closure is axially recessed to form a socket *14 which opens in'the outer end ofitli'eclbsure- V Mounted in each .cl'osure is a terminalstructure' which embodies a conducting barf lawman is supportedf'infan 'axia'lly 'extending passage T6 in the inner end ofthe closure; 'The -p assage"16 is expanded, as shown in- 1 7., tofbrm-asat for a seating fiang'e 18 which "restrains the conducting bar against inward movement. A
Theco'nductin'g bar 15 has'an end portionfl9"wliich pr0jects" b'eyondthe innermost end of the closure'in'ember into' 'tlr'efii'iteiior ofthe bodYnWhiIe the-opposite end portion-' projects into tiiesokefl"! and constitutes a mal'e contact' 2 01 The conducting bar is locked in mounted position bynrieans of a lokingring 21 having snapen- 'gagement with thefend portion 1 9 of the conducting bar.
The "end portion forms" a; support and anchor for a contactmemberzz whichis showmas consisting of an elongate coiled "spring of suitable-"conducting inaterial, one-end of this spring being inserted over the endportion I9 and secured as by 's'oldering "or other suitable means. As thus mounted, the contact member 22" extends axially of the connector body, "the freeend "of-the spring being resiliently 'defi'e'ctable;
W-ith the'construction described 'abOve a'nd as shown in Fig. 2, it will'be observed that the contact members 22' are respectively'in 'el'ectrical'contact'with the male contact pins at the ends of the connectonfbut'thatgthe contact members 22 are insulatedjwith respelctto each ;other,their' free ends beingspaced apart and out of elec- "t'ricalcontact withea'chother. p
The wall "10 0f the connectorbody'is circumferentially provided with a plurality of {wall 'open'in'gs"23,. shown as being arranged in degree spaced. r elation circumferentiall y around eac'h of thecontactrnentbersll, 'Theb p eningsassociated "Wiih"bl16f0f the contact members 22 are "spacedfrom "the openings of" the other *COntactQmember 22- longitudinally of the tubular body of the connector.
The connector as described above therefore embodies a "construction inwhich the connector ends are adapted to receive companion plugs, as "generally indicatedby'the numeral 24,- which are connected to conductor sections or-patchcords "2'5i These jpatchcords may be mechani- 'c'all'y' interconnected by the connector of'the present invention by plugging reduced end projecting portions '26 v the connector. The proje'c'ting portions 26 have end'openings or passages 27 which are adapted to receive the adjacent end portion or male contact 20 of the connector and make electrical connection with the associated conductor section.
It will be noted, however, that with the conductor sections 25 mechanically interconnected by the connector of the present invention, the respective sections will be in electrical conducting relation with respect to the contact members 22-22, but the circuit will not be completed between these contact members. It is a simple operation to place circuit components, as exemplified by the resistor 28, into the circuit formed by the conductor sections 25 and the connector of the present invention. As shown, the resistor has pigtails or connection leads 29-29. In order to place the resistor into the circuit, it is only necessary to insert the ends of the respective leads 29 through the proper openings 23 so that they will enter the interior of the tubular body of the connector. The leads are automatically gripped by the coils of the spring which forms each of the contact members 22. The circuit component is thus bridgingly connected between the contact members 22 of the connector. Although only one component is shown, it is believed that it will be evident that a plurality of components may be bridgingly connected between the contact members 22.
Various modifications may suggest themselves to those skilled in the art without departing from the spirit of my invention, and, hence, I do not wish to be restricted to the specific form shown or uses mentioned, except to the extent indicated in the appended claims.
