With particular reference to the figures a specific embodiment of the invention will now be disclosed.

As shown in FIGURE 1 the connector structure of the invention comprises a bulb socket 10 and an electric connector 12. The bulb socket 10 according to the invention includes male and female bullet type contact members 14 and '16 respectively mounted in insulating core 18, which core has recess 20 therein. The electric connector 12 includes male and female bullet type-contact members 22 and 24 respectively secured in insulating body 26 which body includes projection 28 and flange 30 According to the invention the bulb socket 10 and electric connector .12 may be engaged only when the bulb socket 10 and electric connector 12 are in predetermined relative angular positions due to the interfitting bullet type contact members 16 and 22, and 14 and 24 respectively, and the interfitting recess 20 and projection 28.

Also, according to the invention the male and female bullet type connector members 14 and 22, and 16 and 24- are constructed from single blanks of conducting material 3 whereby the bulb socket and electric connector 12 are economically constructed using a minimum number of parts.

More specifically the bulb'socket as shown in FIGURE 4 comprises socket tube 32, core 18, spring 36 and contact members 14 and 16. In assembly, the socket tube 32 is adapted to receive an electric bulb (not shown) at end 38 thereof. Contact members 14 and '16 are provided to contact the terminals of an electric bulb received in socket tube 32. The contact members 14 and 16 together with the insulating core 18 in which they are mounted are urged toward end 3 8 of socket tube 32 by spring 36.

Socket tube 32 includes a flange 40 at end 38 thereof shaped as shown for the connection of the bulb socket to convenient structure (not shown) and also includes a radially inwardly extending flange 42 at the end 44 thereof against which one end of the spring 36 acts. Socket tube 32 further includes an annular groove 45 producing a radially inwardly extending projection located centrally thereof against whichcore 118 isurged by means of spring 36. Bayonet grooves 46 are also provided in end 40 of the sockettube 32 into which projections on an electric bulb received in socket tube 32 may be positioned in the usual manner. 7

Core 18 as illustrated is a generally cylindrical member of insulating material having a flat side 48 coacting with a flat surface 50 on flange 42 of the socket tube to prevent relative rotation between the socket tube and core. Core 18 is also provided with an annular flange 52 about end 54 thereof against which the other end of spring 36 acts to urgethe core 118 against the projection formed by groove 45 in socket tube 32. Further, a transverse recess 56 extending across the end 54 of core 18 is provided to receive the heads 58 and 60 of contact members 14 and '16 respectively. 7 7

Also, in accordance with the invention a recess 20 is provided in end '64 of core 18 extending coaxially with the male contact member 14. Recess 20 is operable in conjunction with projection 28 on the electric connector 12 to prevent interfitting of the contact members with the electric connector and the bulb socket in other than predetermined relative angular positions.

Male contact member 14, as best shown in FIGURE 8, is a tubular member of conductive material having an end 66 which is tapered inwardly axially outwardly of the tubular member as shown. The male contact member 14 also includes the head 60 cooperable with the tabs 68 extending radially outwardly from the contact member 14 to secure the contact member in an insulating body such as core 18.

Also according to the invention the male contact member 14 is formed from a flat blank 76 shaped as shown in FIGURE 7 with inwardly tapering side portions 72 at 'end 74 thereof. Blank 70 is further shaped with a circular portion 76 extending from the end 78 thereof and connected thereto by a strip 80 so that head 60 of male contact =14 may be readily formed from blank 70. The particular configuration of the end 78 of the blank 70 provides support for head 60 of a finished contact member 14 as will be understood by those in the art.

. The female, contact member 16 as best shown in FIG- URE 11 is similar to male contact member 14 except that the radius of the tubular portion thereof is larger than that of the tubular portion of the male contact member 14 so that the male contact member 14 may be in sorted in the female contact member 16. In addition the end 82 of the female contact member 16 has an inner surface which tapers radially outwardly axially outwardly of the contact member.

The blank 84 from which the female contact member '16 is produced is similar to the blank 70 from which the male contact member 14 is produced. The end 86 thereof, however, instead of tapering inwardly from the longitudinal edges is bevelled to provide the tapering inner surface of the finished female contact member 16 as will be understood by those in the art. Also the circular portion 88 connected to the end 90 of the blank 84 and the configuration of the end 90 of the blank 84 is slightly different than the similar members of the blank 70, illustrating a modification wherein the blanks are of simpler shape. i

7 The electric connector 12 as best shown in FIGURE 2 includes an insulating body 92 having passages 94 therethrough in which contact members 22 and 24 are secured. The insulating body 92 further includes an annular axially extending flange 39 on end thereof which provides an insulating boot for the end 44 of the socket tube 32 with the bulb socket 10 and electric connector 12 engaged. Annular radially extending bead 102 is provided at the outer edge of flange 96 and is operable to grip the sides of the socket tube 32 is assembly.

According to the invention a projection 28 is also provided extending from end 100 of the insulating body 92 and as shown surrounds contact member 24. The pro jection 28 is operable in conjunction with the recess 20 of the core 13 to prevent engagement of the electric connector 12 and the bulb socket 10 in other than predetermined relative angular positions thereof. 7

The contact members 22 and 24 have ends 104 and 106 which are entirely to the ends 66 and 82 respectively of contact members 14 and 16 previously described. The ends 108 thereof include axially spaced transversely projecting portions 110 and 112 which, as shown in FIGURE 2, are adapted to wrap around the insulation 114 and conducting member 116 of electrical conductors 118 to firmly grip and make, electrical contact therewith as will be understood by those in the art.

In use the end 100 of the electric connector 12 is positioned over the bulb socket 10 and the bulb socket and electric connector are rotated angularly relative to each other'until the recess 20 and the projection 28 are aligned, at which time the contact members 16 and 22, and 14 and 24 may be interfitted to engage the bulk socket and electric connector. It will be noted that with the structure disclosed the contact members may not be interfitted to engage the bulk socket and electric connector with the bulb socket and electric connector in any but predetermined relative angular positions.

While 'a particular embodiment of the connector structure, and particular bullet type contact members of the invention have been disclosed it is anticipated that similar structures will readily suggest themselves to those skilled in the art with the disclosed invention before them. It is therefore the intention to include all such similar structures as may suggest themselves the scope of the present invention.
