INTBGRah hAXP AND BOC~ET A88~B~Y FOR A ~OTOR V~ICLE
BACKGROUND OF INVENTION
The present invention relates to lamps for motor vehicles;
more particularly, the present invention relates to an integral 5lamp and socket assembly for exterior use which absorbs shock and does not require additional assembly prior to installation in a motor vehicle.
Lamps and sockets such as those addressed in the present invention are used for turn signals, tail lights, brake lights, L0flashers and marker lights on motor vehicles. Presently, the ~ockets and lamps are supplied separately and require assembly before the lamp is installed in a motor vehicle. A prior art lamp and soc~et assembly 100 is shown in prior art Figures 1 and 2. The socket 105 is made of molded plastic and includes metallic contacts 15110 therein which are designed to make electrical contact with the elactrical leads (not shown) on the base portion 120 of the lamp 130. Prior to installation of the assembly into a motor vehicle's lighting system, the Iamp 130, fitted with a plastic sleeve 140 is inserted into the socket 105 and held in place by a biased portion 0150 of metal contacts 110 and fingers 160 (see Figura 2) formed in the interior of socket 105.
The lamp and socket assembly 100 shown in Figures 1 and 2 has several disadvantages. One obvious disadvantage is the extra step required to assemble the device at the point o~ installation into '5the vehicle. Additionally, the lamp 130, which must be supplied .~;~.........

with the plastic sleeve 140 is sometimes damaged upon insertion into the socket 105 resulting in cracked or broken glass. Also, oxide deposits can form on the contacts 110 of the socket 105 before the lamp 130 is inserted into the socket 105. The result can be intermittent electrical contact and excessive heat between the lamp 130 and the plastic portions of the socket 105. Also, the assembled lamp and socket arrangement 100 is rigid and offers no protection from breakage and excessive wear due to vibration associated with a motor vehicle.
10There is a need therefore, for a lamp and socket arrangement for exterior use on a motor vehicle wherein the assembly is - integral and need not be further assembled before i~stallation into the vehicle, thereby reducing installation time and avoiding damage to the assembly during installation.
15There is a further need for a lamp and socket arrangement which includes means for absorbing shock associated with a motor vehicle, thereby extending the life of the lamp.

and an upper portion 300. Lower portion 200 is made of molded plastic and includes an electrical port 210 which mates with a plug (not shown) which provides a source of electrical current to the lamp 500. Three conductors 700 extend from port 210 and will be discussed hereafter. Lower portion 200 also includes a smooth top surface 220 which acts as a flange as the socket 205 is mated with a fixture (not shown) in a motor vehicle.
Upper portion 300 is cylindrical in shape with a circular exterisr 310 and interior 320. Also included are locking tabs 330, the bottom surface 335 of which are stepped to allow the upper portion 300 to be fastened to a fixture ~not shown). The interior 320 og the upper portion 300 includes a formed key 340.
In the preferred embodiment, the upper 300 and lower 200 portions are molded separately to facilitate the formation of intricate shapes in the inside, bottom surface 230 o~ lower portion 200 during the forming process. At the point of manufacture, the upper portion 300 is electrosonically welded to lower portion 200.
It wi}l ~e understood by those skilled in the art the two portions 200, 300 could be joined with an adhesive or even joined though the frictional relationship between outside surface 310 of upper portion 300 and the inside surface 222 of lower portion 200.
Shock mount 400, made of an elastomeric material also has a cylindrical shape with a key way 410 formed in its outer surface 420. The interior of shock mount 400 includes a slot-shaped ~5 aperture 445 which extends from top surface 440 to the bottom surface 450. Extending from bottom surface 450 is a pair of tabs ~, . ~ 213~2~
460, 465, The ends 480 of each tab are curved to match the shape of outer surface 420. Lamp 500, in the preferred embodiment, includes a bulb-shaped upper portion 510, a collar portion 520, and a blade-shaped portion 530. Extending from the blade-shaped ~ `
portion are three lead wires 540. :-~dhile the bulb has a blade-shaped portion 530 and three lead wires 540 in the preferred embodiment, it will be understood that the invention could be practiced with a bulb having a variety of shapes so long as the aperture 445 in shock mount 400 is capable of accepting the shape. Additionally, the lamp 400 could have any number of lead wires 540 and the invention is not limited to use with any number of lead wires and contacts 700.
Figures 4 and 5 depict the assembled lamp and socket assembly , 175. As depicted, upper portion 300 has been inserted into lower portion 200 and aligned utilizing a keying arrangement between key ~ i```"
202 formed in the interior of lower portion 200 and key way 303 formed in the exterior of upper portion 300 (Figure 4). The two i `.
portions are then electrosonically welded to form the socket 205.
Shock mount 400 is inserted into the interior 320 of upper ~-;
portion 300 and aligned therein u~ilizing a keying arrangement between a key 340 formed in the interior surface of upper portion : 300 and a key way 410 formed in the exterior surface 420 of shocX ~;

As depicted in Figure 5, inside bottom surface 305 of upper portion 300 also includes three tapered orifices 360 which allow the passage of lead wires 540 through upper portion 300.
Additionally, lower poxtion 200 includes three tapered indentions 240 which house the ends of lead wires 540.

Depicted is the relationship between the blade-shaped portion of the lamp 530 and the slot-shaped aperture 445 of shock mount 400.
Additionally depicted is the relationship between the shock mount 400 and the upper portion 300 and the relation between upper portion 300 and lower portion 200. Also shown is the keying means 410, 340 between shock mount 400 and upper portion 300.
Flgure 7 is a top view, in section depicting the workings of : three electrical contacts 700. In the preferred embodiment, eachcontact 700 lncludes two fingers 705 which form a slot 710 in the center of the contact 700. The contacts 700 are designed to house lead wlre 540 within slot 710. For illustrative purposes, Figure 7 depicts contacts 700 in various positions with respect to lead wire 540. For example, in the Figure, contact 700a is completely inserted into the assembly 175 with lead wire 540 completely housed within slot 710. Contact 700b is depicted as it is being inserted into the asisembly and the fingers 705 are being pushed apart by ~ 213~2~ :
lead wire 540. As depicted, the inside, bottom surface 230 of lower portion 200 includes substantially V-shaped notches 720 which are designed to interact with fingers 705 forcing the fingers closed and securing lead wire 540 in slot 710. :
Figure 4 illustrates the location of installed contact 700 with respect to other parts of the assembly 175. As depicted, contact 700 extends through tabs 460 and 480 of shock mount 400 and fingers 705 are housed in substantially V-shaped notch 720 (not ~
shown). Each contact also includes tang 750 which, as depicted in .
Figure 4, locks the contact 700 into placa in its fully installed position within the socket 205. ` ~ `
In the preferred embodiment, the integral lamp and socXet assembly is assembled by first placing the upper portion 300 onto `
the lower portion 200 and electrosonically welding the two portions together. Thereafter, the shock mount 400 is inserted into the :., ,,.".. . .

Alternatively, a gasket may be placed on the smooth top surface 220 of lower portion 200 prior to assembly of the lamp and socket assembly 175.
As the forgoing discussion indicates the present invention for an integral lamp and socket arrangements solve the problems associated with a lamp and socket which must be assembled at the point of ~nstallation into a motor vehicle and the problems ~ ;;
associated vibrations and rigidly mounted lamp and socket assemblies.
While the lamp and socket assembly of the present invention has been de~cribed by reference to its preferred embodiment, it will be understood that other various embodiments of the device and ~0 method of the present invention may be possible by reference to the `
specificatlon and the appended claims. Such additional embodiments shall be included within the scope of the appended claims. ;
