Claims. 1 Cl. 339-217 invention relates to electrical connectors of the mating pin andsockfet type and, moreparticularly, to av socket coritact' having means to 'transformthe end to' "a closed entry. l One common form of electrical connector includes ,a
,iniale or pin element 'coupled'to one conductor of the circuit and a mating socket contact' coupled'to the other contacts, the electiicalci-rcuit is completed. In the past it has been found desirable to include means in the socket fcontact whichwould apply a pressure to the contained 'pin' ciopntz'lct to ensure 'proper'electrical connection and jto jincrease theipfessure necessary to withdraw thepin act froin the socket. One common formof' socket *co act including such spring pressure'iineans comprised a oeket having a plurality of spring-likejfingers's'urrounding the pin element. For easef'of manufacture the tubular slit to, form the 'springbarrel of the socket contact likefingers. M H g In use, such a, socket contact had many disadvantages.
The foremostamong these disadvantages was the fact that this type of contactwas not'a-closed entry? In accordance with my invention; A 'Fig. 3 is an end view in conductor to. be joined. By engaging the pin and socket oth'er-iwords'," because. the spring fingers extended .along Ethetotal length. of the.contactsend;-the:barrel of the? socket could be overexpanded to accept an oversized pin, and
.thus the socket contact would bedamaged through the a use of 'an improper mating portion.
In order to overcome this disadvantage of opened contacts, unitary contacts have beendesigned in which the end first accepting the pin was closed and various other methods of providing the necessary spring pressures were utilized. Soine of these methods included the use of ads 7 2,981,924 Patented 25, 1961 removed from the panel. A closed entry adapter is .utllized to restrict the entrance of oversized pin contacts and has openings therein through which the-lock r v cross section taken along the lines 3- 3 of Fig. 2; I s p p Fig. 4 is a side view partly in crossse'ction of themoperating pin and socket contacts of myinvention mount- .ed in a supporting insulating housing; and
Fig. 5 is a perspective view of an alternate embodiment' of the closed entry adapter of my invention,
"Referring to Fig. l of the' drawing; an'exploded "view of the socket'contact assembly in accordance withthe principles of my invention is therein seen to cornpri'se a socket contact 10 and closed entry adapter 12. The socket contact 10 includes a wire receiving barrel 14 in "which the bared wire to be joined isjinsertedand an insulation grip 15.

' Another object 'of my inventiongis to provide a novel .closedentrycontact having springfinger elements along substantially the entire lengthof the tubular barrel.

Still another object of my{ invention is to -provide a closed entry socket contact structure which may be easily" 1 removed from its" associated insulatingpanel. x j a f One of the features of my invention isthe provision of-a socket contact having substantially its en'tire'barr'el slitto formspring'finger contactelements toapply pres- 7 [:sure to arnatingpin contact; Up'standin'g from;the tubu arbodyi-portion]ofgtheilsocket contact-is a plurality of locking {elements which cooperate. withshouldjers in the fingers along a length of barrel, not includingthe entrancez' vWhile these sockets have performed satisfacadapters. The locking-elements 22 of the adapter ex tend through the opening 26 as hereinafter vexplained.
In use, as shown in Fig. 4, an electrical conductor 13 has its insulation 19 stripped back and inserted in the barrel 14 which iscrimped thereto. The insulation grip 15 of thesocket contact '10is crimped about the insulation 19 in the usual manner. The socket contact 10 'and closed entry adapter 12'are inserted in the barrel of the housing 44, and during the insertion, the spring locking members 22 are depressedto pass through the r'estricted portion.

Fi i j whi-ch may be easily depr sedglsoig thatjjthe socke may v engage the pin contact making electrical and mechanical connection thereto positive.
V The closed entry adapter 12 prevents-the insertion of an over-sized pin member. 7 i r Referring to' Fig. 5 of the drawing, an alternate em bodimenfof the closed :entry adapter of my invention'is 46 in the mounting -memtherein shown to utilize a slit beta Thus the slit 4 6imay be opened,'fand,the closed entry adapter. may be; '1nounted overthe. spring-like fingersmy'invention need not have four fingers, but may; be
made with two or any other number of fingers. Preferably, the round sides of the socket contact should be flattened on opposite sides to permit the closed entry adapter to be disposed over the socket contact. To re move the contact from the panel, a tubular tool is positioned over the locking elements 22, depressing thesame and permitting withdrawal of the connector from the panel; t
I have thus described my invention, but I desire it understood that it is not confined to the particular forms or uses shown and described, the same being merely i1- lustrative, and that the invention may be carried out in other ways without departing-from the spirit'of my invention, and therefore, I claim broadly the right to employ all equivalent instrumentalities coming within the scope of the appended claims, and by means ofwhich, objects ofmy invention are attained and new results accomplished, as it is obvious that the particular embodiments herein shown and described are only some of the many that can be employed to attain these objects and accomplish these results.
