Definitions

  • This invention relates to the establishment of weather-proof electrical circuits between lamp sockets and wiring harnesses. It particularly relates to connectors which form couplings between lamp sockets and wiring harnesses to provide weather-proof electrical connections, and which, once fastened, are hard to remove.
  • the invention has further reference to the assembly of lighting fixtures on a production line, enabling a special lamp socket, complete with a lamp, to be placed in a housing and subsequently permitting a connector and associated wiring harness to be coupled to the lamp socket to complete electrical connections between the lamp and the harness.
  • the prior art includes lamp sockets which have been complicated and relatively expensive. Many of these prior art lamp sockets have been preconnected to the wiring harness thus avoiding the problems associated with making connections during assembly in automobile assembly plants and the like, but requiring that lamps be installed as a final assembly step in order to avoid lamp breakage. With other prior art lamp sockets it has been necessary to shrink tubing in order to provide a weather-proof seal between the lamp sockets and wiring harness. It has also been necessary in some cases to swedge the lamp socket after assembly to provide a seal between the socket and the lamp housing. This last procedure has meant that the socket is not removable and that the lens will have to be removed to enable replacement of burnt out lamps. With one known device, a pig-tail harness has been employed which required a number of individual connections to the wiring harness in an inefficient and costly manner.
  • Yet another object is to provide an economical seal between a connector and a socket to prevent moisture from penetrating into a lamp housing.
  • FIG. 1 is a sectional view of an embodiment of the assembled lamp socket structure illustrating a completed connection between a wire harness connector and a lamp socket,
  • FIG. 2 is a bottom view of the assembly of FIG. 1,

  • FIG. 17 shows the connector and cable harness after coupling to the socket in FIG. 16, and
  • FIG. 18 is a view of an assembled socket and connector after removal from the reflector housing.
  • This invention relates to a lamp socket and connector structure having relatively few parts, making it easy to fabricate and assemble.
  • the external configuration of the lamp socket structure insures straight-line and fool-proof orientation of the lamp socket with the housing panel opening during installation.
  • the connector provides a good connection between the lamp socket structure and a cable harness.
  • the lamp socket structure assembly is provided with a unique resilient compression ring and detent arrangement which insures a positive pressure interlock with the housing wall and which provides against accidental dislodgment of the lamp socket structure from its operative use position on the panel housing.
  • the compression ring cooperates with the annular shoulder of the lamp socket so as to accommodate housings constructed of various materials and having various wall thicknesses.
  • the overall design of the lamp socket and connector struc ture provides equipment which can be quickly, easily and economically assembled into the lamp socket housing. No complicated fabrication steps are required to manufacture and assemble this structure.
  • the lamp socket structure of the instant invention is adapted to quickly, easily and lockably receive the connector which, in turn, is coupled to the individual wire leads of the wire harnesses utilized in the external electrical system of the vehicle.
  • the wire leads of the wire harness are coupled to the individual contact elements contained within the lamp socket structure.
  • the wire leads are not otherwise connected to the individual contact elements, and the individual contacts are automatically kept free of pressure from external wire harness strains. In this way, bulb contact pressure is independent of external wire harness strains, thus eliminating one of the main problems encountered in the devices of the prior art.
  • the unique construction embodied in the lamp socket structure permits its adaptability to provide a variety of focal ranges while maintaining the same basic internal structural features and the same internal interrelationship of its components.
  • a completely internal ground circuit capability is provided which enables the lamp socket structure to be used with either metal or plastic housings.
  • the lamp socket structure also incorporates therein a built in structure which is useful in assembly and which provides for the use of fiber optic channels, if desired.
  • the lamp socket structure is operated in such a manner and is so configured that only a single reflector (housing) opening is required. No irregular surface is required on the housing for detenting.
  • the lamp socket structure is constructed so that there are no exposed electrical contacts, thus providing a lamp socket which is not only safe in operation but which is not susceptible to failure due to dirt or other foreign particles finding their way into the internal portion of the structure.
  • boot seals are utilized which provide individual wire lead sealing and which cooperate with the lamp socket structure to provide a protected boot seal-lamp socket body juncture.
  • the lamp socket structure includes a flange collar element 22 and a main body 23.
  • the main body housing 23 is provided with a bulb receiving cavity 24 at one end which is adapted to receive a twist lock bulb 25 therein.
  • a contact receiving and retaining cavity 26 is provided within the central part of the body housing 23.
  • the contact receiving cavity 26 is in open communication with the bulb receiving cavity 24.
  • Contact elements 27 are inserted through the bulb receiving cavity 24 into their operative use position in the contact cavity 26.
  • Each of the contact elements 27 is provided with a resilient curved bulb contacting portion 28 at one end thereof.
  • each of the contacts 27 is provided with a reverse leaf spring extension 29 which is adapted to slidingly, wipingly and springingly make contact with terminal plugs 31 inserted into the lamp socket structure.
  • a lip extension 30 is provided within the contact cavity 26 so as to lockably retain the contacts 27 therein. Upon insertion of the contacts 27 into the contact receiving cavity 26, the leaf spring extension 29 springs outwardly behind the lip extension 30 so as to prevent accidental removal or dislodgment of the contacts 27 from the contact cavity 26.
  • the terminal plugs 31 are held in terminal plug socket cavities 6 of a connector C.
  • the connector C incorporates extension towers 4 located within a protective skirt 8 sealed in this view to the socket 21 by a seal at 15.
  • the terminal plug socket cavities 6 are positioned in the connector C so that terminal plugs 31 placed therein come into positive slip-proof wiping contact with the leaf spring extensions 29 of the contact elements 27.
  • FIG. 2 illustrates, in a simplified way, the arrangement of the base of the lamp socket structure of FIG. 1 with the connector removed from view.
  • the flange 37 is shown to have ridges at 41 and 43 as well as an optic tower at 4. Components to receive a connector C are indicated at C.
  • a standard ground contact element 36 is provided on the lamp socket structure 21 to engage the base of a bulb element mounted therein.
  • the upper ring collar element 22 is provided with an annular flange portion 37 having a circumferential seating lip extension 37a which is configured to seatably and retainably engage a resilient compression ring member 38 (FIG. 1).
  • the compression ring 38 cooperates with the base of annular shoulders 39, 40 and 41 of the ring element 22 to retainably engage a reflector housing wall therebetween.
  • the ring collar element 22 is provided with positive orienting or aligning shoulders 39, 40 and 41 as shown in FIG. 3, which are configured to matingly engage corresponding recesses in the opening provided through the reflector housing panel into which the lamp socket structure is mounted.
  • a waterproof rubber boot seal 10 is selectively provided for mating engagement with the external walls of the extension towers 4 which define terminal plug socket cavities 6.
  • the boot seal 10 is provided with an opening 12 through which the terminal plug 31 passes to be locked into the connector C within the socket cavity 6.
  • the boot seal opening 12 is normally covered by a thin wall membrane which is punctured when the terminal plug 31 is inserted therethrough. Further, the opening 12 actually stretches to accommodate the temiinal plug 31, thus providing a weatherproof fit around the terminal plug 31 which prevents moisture and/or foreign particles from entering the interior of the lamp socket structure.
  • the ring element 22 can be placed in a variety of positions along the longitudinal axis of the main body housing 23 so that the lamp socket structure can be adapted to various focal lengths. After ring element 22 has been properly positioned on the body housing 23 so as to achieve the desired focal range, it is then ultra-sonically joined or heat staked thereto at selected points along juncture lines 43 and/or 44.
  • FIG. 5 shows in detail the various components of an embodiment of the lamp socket and connector structure.
  • Weatherproof boot seal units are shown at 10 with terminal plug openings 12 therethrough.
  • Each of the individual boot seal units 10 is cylindrically configured to matingly engage the external walls of the individual temiinal plug cavity socket extension towers 4.
  • the protective skirt 8 of the connector C is shown with slots at 74 and 74 to engage elements on the opposite side (see 41, FIG. 2) of an annular pressure ring retaining flange 37.
  • a lower body housing 55 which contains contact spring cavities 26 and a ground strap cavity or channel 50 therein which are in open communication with the terminal plug cavities 57 as will be hereinafter described.
  • the body housing 55 is provided with three guide retaining arms 58, 59 and 60, respectively, that are adapted to matingly engage the upper body housing 61.
  • the lower body housing 55 is provided with an annular compression ring retaining flange 37 and circumferential lip extension 37A upon which the compression ring member 38 is seated.
  • Contact elements 63 and 64 are provided having curved bulb contact portions 65 and 66 at one end thereof, respectively, and leaf spring terminal plug contact portions 67 and 68 at the opposite end thereof. It should be noted that the contact elements are configured so that the tip ends 69 and 70 of the contact elements bear against the mid-portion of the contact elements. This tends to impart a more positive contact pressure against the base of the bulb inserted thereagainst.
  • a ground strap element 71 is provided having a curved end portion 72 which is adapted to engage the upper body housing 61.
  • the ground strap 71 is also provided with a leaf spring extension 73 which is adapted to engage a terminal plug element 31 inserted into the terminal plug receiving cavity.
  • the upper body housing 61 is provided with a bulb engaging cavity 74 therethrough. Suitable grooves 75 are provided within the bulb engaging cavity 74 which are adapted to lockably engage the ears on the base of a standard twist lock bulb.
  • Orienting alignment shoulders 77, 78 and 79 are provided on the upper body housing 61.
  • the alignment shoulders 77, 78 and 79 have different thicknesses and are configured to matingly engage corresponding recesses provided in the opening in the lamp socket reflector housing into which the lamp socket structure is mounted. This alignment or orienting feature insures that the lamp socket structure can only be inserted into the reflector housing in its proper use position. Thus, the result is fool-proof installation of the lamp socket structure into the lamp socket reflector housing.
  • a tower 80 is provided on the lower body housing 55 which may be adapted to receive an optical fiber therethrough for aiming at the filament of the bulb. This tower serves also as an aid in positioning the lamp socket relative to the reflector housing.
  • the connector C is provided with a plurality of extension towers 4. Each of the towers 4 defines a terminal plug socket cavity 6 therethrough.
  • the connector C is also provided with a protective skirt 8 which is coextensive with the extension towers 4.
  • the skirt 8 acts as a protective guard for the towers 4 and the boot seal units 10 mounted thereover.
  • the presence of the protective skirt 8 on the connector C permits its installation on the lamp socket structure without any manual handling of the boot seals 10 or of the terminal wire ends leading into the socket cavities 6. The worker merely grasps the external protective skirt 8. Thus, there is very little likelihood that damage will occur to the boot seal connection or individual wire leads during the installation process.
  • Each of the individual boot seal units 10 has a cylindrical configuration for mating engagement with the cylindrical outer wall of the extension tower 4.
  • the boot seals 10 represent a distinct improvement over the boot seal structures of the prior art.
  • the boot seal structures of the prior art have been mounted over the entire base of the lamp socket structure.
  • the peripheral sealing edge of the prior art boot seal structure has been located on the exposed outer wall surface of the lamp sockets, thus exposing them to damage and to failure of the sealing action. Failure of the boot seals of the prior art have exposed all of the circuits leading into the lamp socket structure.
  • the boot seals 10 of the instant invention provide independent sealing for each circuit. The result is a more readily controllable seal joint because the sealing action is around each individual wire element and not around the entire lamp socket body housing.
  • the unique seal design requires substantially less rubber material than the relatively massive boot seals of the prior art. This brings about a significant cost reduction in the overall cost of the lamp socket stnicture.
  • the design of the boot seals 10 can be varied as desired as long as they provide a water and dirt proof seal for the connections between the terminal plug elements and the connector.
  • FIG. 7 three different models of the lamp socket structure are shown to illustrate how the lamp socket structures can be readily adapted to provide for three different focal ranges. While the external configuration of the upper body housing 61 (including C from FIG. 2) vary in the different models, the connectors C and the internal interrelationships of the various components, channels, socket cavities and the like, remain constant. The relative positioning of the external flange 62 and of the shoulders 77, 78 and 79 on the lamp socket structure is changed on each model so that the position of the lamp socket structure is axially adjusted in relation to the housing panel upon which it is mounted. This enables the production of different focal ranges as desired, without changing connector tooling. In essence, only the plastic tooling needs to be changed for each model; the metal tooling remains the same.
  • the upper body housing 61 of an exemplary embodiment of the lamp socket may be provided with three longitudinally extending orienting or alignment shoulders 77, 78 and 79, respectively.
  • Shoulder 78 is provided with a detent extension 83 at the base thereof which engages a slot provided in the housing panel to lockably retain the lamp socket structure thereon.
  • Shoulder 77 is provided with a stop shoulder 84 at the base thereof which also cooperates with the housing panel to effect a positive seating of the lamp socket structure into its operative use position.
  • Shoulder 79 may be provided with an optical fiber channel 49 therethrough and may support an optical director tower 80 thereon.
  • the adaptability of the lamp socket structure to operatively engage housing panels of varying thicknesses is shown in the composite view of FIG. 9.
  • the upper portion of the composite view of FIG. 9 illustrates engagement of the lamp socket structure with a thin housing panel 86.
  • the compression ring 38 compresses sufficiently to permit engagement of the housing 86 between the compression ring 38 and bases of the alignment shoulders 77, 78 and 79, respectively, which are positioned on the upper body housing 61. As previously described, the compression ring 38 is seated upon the annular flange 37 of the lower body housing 55.
  • the lower portion of the composite view of FIG. 9 illustrates engagement of the lamp socket structure with a relatively thick housing panel 87.
  • the compression ring 38 is merely compressed to a greater degree to accommodate the thicker housing panel 87.
  • This capability to automatically adjust to a variety of panel housing thicknesses clearly imparts great versatility to the lamp socket structure.
  • lamp socket structures can be mass produced for use in equipment where wide variations in the thickness of different types of housing are encountered.
  • the use of the compression ring 38 provides a positive and relatively vibration-free engagement of the lamp socket structure with the housing. Inasmuch as the compression ring 38 is actually compressed when the lamp socket structure lockably engages the housing, the compression ring 38 exerts a constant retentive pressure against the back of the housing during the entire period in which the lamp socket structure is mounted in the housing.
  • FIG. 9A Further use of a connector C similar to the connector C with a socket is illustrated in FIG. 9A.
  • a lamp socket is molded as a part of a lamp housing at H.
  • the connector C" is attached to the harness and may be sealed at the point of wire entry by a boot 10.
  • an upper socket 63 is attached to the housing by heat staking or ultrasonic means after the socket terminals have been located inside the assembly.
  • the fingers 89 protruding from the connector have leading angles 91 which enter the appropriate slots 92 of the socket until the locking edge 93 passes the shoulder 94 on the socket structure.
  • the skirt 8" of the connector C" surrounds the socket body limiting the amount of dirt and moisture which gets to the flat part of the connector 97 where a compression seal 98 is in contact with a sealing lip 99 of the socket. This seal prevents any moisture, dust, etc. from entering the lamp housing.
  • the location of the slot 95 mentioned above precludes any inter ference with the removal tool of the rubber seal during the forceable removal of the connector from the socket.

  • FIG. 16 shows a portion of a reflector housing 87 with which the invention has utility. This figure shows also the lower portion of a lamp socket C positioned in the housing 87 in position to receive the connector C and the associated cable harness 90. It should be noted at this point that C and C may be separated after they have been placed together, as in FIG. 17. Generally, the mating elements on the lamp socket side (17 in FIG. 9) and the corresponding elements in the connector are formed to be mated more easily than they can be separated, but they are designed to be separable if necessary.
