WIRE TERMINAL.

Application filed February 1, 1926. Serial N o. 85,101. i I

The objects of this invention are to provide a terminal clip for wire ends, cord tips and the like, which will securely hold the inserted wire end, tip or other element and make good electrical contact therewith, which can be readily operated to instantly grip or release the wire end and which in addition to these practical advantageswill be'of neat appearance, small compact form to and inexpensive construction The foregoing and other desirable objects are attained b certain novel features of construction, com ination and relation of parts as hereinafter set forth in detail.

In the drawing accompanying and forming part of the specification, the invention is illustrated embodied in a number of different forms and applied to a number of different uses, but it isto be understood that the structure may be further modified and the devicemay be applied to other purposes without departure fromthe spirit and scope of the invention as hereinafter defined and broadly claimed.

Figuresl and 2 are side and end views respectively of a form of the terminal as constructed for and used with a spring cord tip socket.

Figure 3 is a view of the tip end of the clip.

together will open to receive the wire end and which when released will separate in a way to yieldingly grip between them, the inserted wire end or other element. V In the first disclosed form. of the inven- 5 tion, Figuresl to 5, the clip is made of a single continuous strip of sheet metal bent into substantially U-form to provide an intermediate base or attaching portion 12 and two more or less parallel side arms 13, 5.5 14. The end of the first of these side arms is turnedat an angle at 15 and perforated at 16 to form one'of the jaws ofthe clip, The cooperating aw is provided by angularly turned extensions 17, 18 on the other spring arm, standing at opposite sides of the first jaw and in overlapping relation therewith. The aw'element 18 is perforated atv 19 and this element is shown as formed out of the body of the spring arm 14 by severing the latter alongthe parallel lines 20 to near the end of the arm and then. bending this severed portion inwardly substantially at a right angle parallel to the angularly bent end 17. The cutting of this secondary jaw out of the main jaw leaves the latter (17) j, with an end opening at 21 substantially in register with'the opening 19.

Figure 4 shows how the secondary jaw 18 is partially severed from and bent up out ofthe main jaw 17 and this View also shows how the parts can be pinched together to bring the openings 19, 21 in the one jaw in register with the perforation 16 in the other jaw and how after the wire end cord tip, bus bar or the like has been passed endwise through the openings in the pinched-together jaws, said jaws will spring apart when released to firmly grip the inserted element therebetween.

'Wherethe terminal is to be used with a spring cord tip socketor the like, such as indicated "at 23 inFigures 1 and 2, mounted on a panel 24;, the baseof the clip may be fashioned as or attached to. a pin or plug for entry in such a socket. This pin is indicated at 25-and is shown as attached to the base of the clip by having a neck portion 26 at the outer end of the same extended through an-opening provided in the base of th'e'clip and headed over at 27 to rivet the parts securely together; The form of the pin mayyvary to suit different kinds of sockets, but in the present instance it is shown as havinga larger outer end or body portion tofit the bore of the socket and a reduced innerend extension 28 to engage the spring fingers 29 at the inner end of the socket.

For identification purposes the clips may be marked as'by impressing 'suitableidentifications 30 directly on the sides" of the spring jaws (Figure 5) or by applying marker plates 31'over the shanks of the pins 25. The latter method has the advantage ofbeing readily changeable. These markers maybe made of suitable sheet material punched to fit over theshanks of the pins I and may be split as indicated at 32 so as to hold themselves in place by spring tension.

The form of the invention illustrated in Figures 6, 7 and 8 differs from the first mainly in the shape and structure of the gripping portions of the spring jaws. In-' It will be noted in Figures 7 and 8 that these ward extensions ofthe first jaws.

transversely extending lugs are turned inward from diagonally opposite edges of the spring arms so as to bring the two ends 1I1l30 overlapping relation so that they are confined or limited in their spreading action, one by the other. y

In the panel mount form of terminal shown in .FiguresQand 10, the overlapping perforated .jaw structure of Figures 1 to 5 is employed, but in this case the spring arms 13, 14 instead of being bent up in complete U-form, are turned up from the sides of a base piece or connecting strip 37 disposed substantially at a right angle to the parallel planes of the side arms, but in a plane parallel to the length of said spring arms.

When secured by a screw or other fastening device 38 on the panel or other support, this form of base brings the spring jaws of the terminal close up against the face of the panelin substantial parallelism, instead of projecting outwardly therefrom as would be the case with the form and arrangement of base shown in the preceeding figures. V

Another special feature of the terminal shown in Figures 9 and 10 is its double ended character, there being an extra set of the spring arm jaws 13 14 shown extended from the opposite end of the supporting base 37 substantially as continuations or vrear- The two sets of jaws are rendered independently resilient in the illustration by cutting down' the two sides of the double clip, as indicated at 39. a

The form of clip last described is particularly useful for mounting on a panelor flat base and may be in either single or doubleform. The singleform of terminal is illustrated in Figure 11, which shows the structure substantially the same as in Figure 10, but having only the one pair of wire gripping arms connected at'their ends by a flatwise arranged base which can be secured by a screw or the like in fiat engagement upon a panel or other suitable support. From the disclosure it will be seen that the terminal of this invention is a particularly simple structure, compact and inexpensive, that it can be quickly opened to and is held in good conducting relation, considered from the electrical standpoint. The pin terminal and the panel type forms of bases illustrated answenmany requirements and enable theterminal to be used in many different ways. .It will be apparent that by modifying the form of-the base structure,

the terminal may bervpositioned in different angular relationsand be made applicableto various electricaldevices as for exampleQby suitable lnodificationl the terminals might be used in conjunction with an, ordinary-telephoneplug.
