`Other objects, advantages and novel details of construction of this invention will be made more `appa-rent as this description proceeds, especially when considered in connection with the accompanying drawings, wherein:
`FIGURE 1 is a partially broken-away side view of assembled connector structure according to the invention.
FIGURE 2 is a fragmentary longitudinal section View of the bulb socket illustrated in FIGURE 1.
FIGURE 3 is a left end View of the bulb socket illustrated in FIGURE 2.

FIGURE 5 is a partly broken away side view of the harness connector illustrated in FIGURE 1.
vFIGURE 6 is a left end view of the harness connector illustrated in FIGURE 5.
FIGURE 7 is a right end view of the harness connector illustrated in FIGURE 5.
FIGURE 8 is a perspective view of the contact members of the bulb socket shown in FIGURE 2 with the core member of the bulb socket shown in dashed lines.
FIGURE 9 is a longitudinal section of a modified bulb ysocket and harness connector similar to that illustrated in FIGURE l in which the contact members are of equal diameter.
FIGURE l0 is a perspective View of lthe contact members of the bulb socket shown in FIGURE 9 with the core member of the bulb socket shown in dashed lines.
With reference to the drawings, a particular embodiment of the invention will now be disclosed.
As shown in FIGURE l, an electric light bulbv generally indicated 10 is connected to the electric conductors 12 and 14 in accordance with the invention by means of the bulb socket 16 inserted in housing 18 and the harness connector 20 in assembly.
With the connector structure shown, the bulb socket 16 may be secured to the housing 18 separately from the harness connector 20. The harness connector 20 may then be assembled with the bulb socket 16 to provide a sealed electrical connection having a predetermined polarity between the conductors 12 and 14 and the laments 21 and 23 of light bulb 10 with the bulb socket 16 and harness connector 20 in any relative angular position. Such connection will be sealed against Water, dust and corrosion.
More speciiically, the bulb socket 16 comprises a socket tube 21, core 22, spring 24 and contact members 26 and 2S.
The socket tube 21 has axially oifset bayonet slots 30 in one end 32 thereof adapted to receive axially offset lugs 34 of an electric light bulb 10 inserted within the socket tube 21 to secure the bulb and socket tube together in a predetermined angular position.
3 Thus a connection of predetermined polarity is established between bulb filaments 21 and 23 connected to bulb terminals 52 and Si) respectively with conductors 12 and 14 respectively through bulb socket 16 and harness connector 2t) when the bulb 12 is positioned in bulb socket 16 and harness connector 28 and bulb socket 16 are assembled.
The socket tube 21 is further provided with a radially inwardly extending annular ilange 36 at the other end 38 thereof against which one end of the spring 24 is seated. Annular groove 40 is provided centrally of socket tube 21 and provides internal annular abutment 42 which is operable to prevent the core 22 under the influence of spring 24 from passing out of the end 32 of the socket tube 21.
'The core 22 is of insulating material shaped as shown and is positioned within the end 38 of the socket tube 2.1 for axial movement with respect thereto. The core 22 is held against rotation relative to the socket tube 21 by the configuration of the flange 36 and its own cross-section as shown.
.Core 22 is provid-ed with a radially outwardly extending annular flange 44 adjacent the end thereof within the socket tube 21 against which the other end of the spring 24 bears and which in turn bears against the abutment 42 when the bulb 18 is not inserted within the socket tube 21. With the bulb 10 inserted within the socket tube 21, the core 22 due to the annular flange 44 thereof having smaller outer diameter than the inner diameter of the socket ytube 21 is allowed to tilt slightly under influence of spring 24 to provide a solid electrical contact between the'bulb contacting ends 46 and 48 of the contact members 26 and 28 and the terminals 50 and 52 of the light bulb 10 which may be of different lengths.
As best shown in FIGURE 4, the end 54 of the core 22 is provided with a transverse recess 55 in which the bulb Contact ends of the Contact members 26 and 28 are positioned. Thus the terminals t) and 52 of the bulb 10 are not subject to detrimental shearing forces on being rotated into contact with the bulb contact ends 46 and 48 of the contact members 26A and 28 during insertion of the bulb in the socket tube 21.
A stepped recess S6 isprovided in the end 58 of the core 22'as shown. The contact members 26 and 28 are mounted in the stepped recess 56 and extend through vthe coreV 22 as shown and are secured in position in core 22 by the bulb contact ends 46 and 48.
As shown in FIGURES l through 8, the contact memybers 26 `and 28 comprise cylindrical harness connector contact ends 60 and 62, the previously indicator bulb Contact ends 46 and 48 and connecting strips 64 and 66 .therebetween respectively. It will be noted that in accordance with the invention the harness connector con- -tact end 62 ofthe Contact member 28 is of smaller diameter than `the harness connector contact end 60 of contact member 26. In addition the harness connector contact end 62 of the contact member 28 is positioned axially inwardly of the socket tube with respect to the harness connector contact end 60` of the contact member 26.
'Ihe harness connector 28 as shown best in FIGURES 5 through 7 comprises a body member 68 of insulating material having a cylindrical shaft portion '70 extending from end 72 thereof. Body member 68 also includes the annular axially extending ange 74 forming a Iboot for receivingthe end 38 of the socket tube 21 to seal the connection between the harness connector and bulb socket in assembly thereof las shown in FIGURE l.
The harness connector 20l also includes the contact members 76 and 78 having cylindrical concentric bulb socket contact ends 80 and 82 respectively, secured to the stepped shaft 7i) as shown -best in FIGURE 5. The contact members 76 and 78 are adapted to tit within and makeelectric-contact with the cylindrical harness connector- contact ends 62 and 60 respectively, of the contact members 2S-,and 26 of the bulb socket 16. The contact members 76 and 78 also include connecting strips 84 and 86 which extend through the body member 68 and are secured to the electric conductors 12 and 14 respectively.
A modification of the connector structure illustrated in FIGURES l through 8 is illustrated in FIGURES 9` and l0'. In the modified connector structure similar parts have been given similar numbers followed by the letter a. The cylindrical portions 64m and 62a of the contact members 26a and 28a of the bulk socket 16a of FIG- URES 9 and l0 are of the same diameter. The harness connector contact end 62a of the contact members 28a is, however, segmental to permit passage of the connecting strip 64e of the contact member 26a through the core member 22a. The connecting strip 64a is offset slightly radially outwardly at 88 to prevent shorting with the bulb socket contacting end of the contact member 76aI of the harness connector 20a to the strip 64a with the harness connector 29a in assembly with the bulb socket 16a. Likewise the contact members 76a and 78a of the harness connector 28a in the connector structure shown in FIGURES 9 and lO are of the same diameter.
It will be evident that with the connector structure of the invention the harness connector 20y is easily piloted into engagement with the bulb socket 16 either before or after the socket tube is assembled with the housing 18. Further it will he evident that with the structure disclosed it is impossible to connect the bulb socket 16 and the harness connector 20 of the invention so as to provide a circuit having the wrong polarity between iilaments 21 and 23 and conductors 12 and 14 through the contact members 28 and 76, and Sil and 78. Also connection may be made between the harness connector 2t) and the bulb socket 16 with any angular relationship therebetween. In addition the connection thus formed will be sealed against water, dust and corrosion Iby the boot structure 74 which lits snugly around the end of the bulb socket 16.
