Description
2167~7~--UNlV~8AL TR~TT~ LIGHT LOCATOR
FIELD OF THE INVENTION
The present invention relates to a universal eleetrieal and meehanieal interfaee eapable of adaptation to a variety of eonneetor assemblies. The deviee of the present invention is based on the principle of testing and connecting each pin separately with a versatile eonneetor. The user follows a pattern for seleeting the eorreet wire for eonneetion without the need for speeial tools.
Separately connecting eaeh pin offers unlimited versatility with various eonneetors and the resistor prevents destruetion of fuses.
BACKGROUND OF THE INVENTION
- Existing trailers must be equipped with taillights whieh operate in eoncert with the taillights of the towing vehiele. The conventional trailer interfaee, as we know it today, contains a wide assortment of conneetors including 3- pin, 4 pin, 5 pin or 6 pin, round, square or flat. The eleetrieal eonneetions ean be the ground, running lights, left blinker/brake light, right blinker/brake light, electrie trailer brakes or a eharging eireuit.
A problem assoeiated with trailer eonneetors is the lack of uniformity with the automobile connectors. Existing connector interfaces are limited to certain size and shape connectors. The mechanical eonnection between two 3 pin connectors may be impossible because of the varying pin and hole sizes. A connector 012095:HIS:dld:8781 216777~
which could adapt to all hole and pin sizes would be an important improvement. Even if the mechanical connection is adequate, the electrical connection may be inconsistent. The automobile plug consists of an entire set of male pins which must conform to an entire set of female receiving holes in the trailer plug. A
trailer interface which tests and connects each pin separately would be advantageous.
The procedure available today requires the user to spend considerable time connecting different trailer interfaces. Each time a new trailer or a new automobile is connected, the user must spend extra time determining the proper connection sequence.
Special tools may be required for different trailer connections which also can add to the expense of the project.
The current procedure for connecting the interfaces is also problematic in that it is a trial and error type approach with the consequences of destroying circuits and fuses during each connection. No system for indicating a proper connection, before destroying a fuse, exists. If the wire for the brakes is accidentally connected to the charging circuit, the brake fuses would be destroyed while testing the connection. The user must connect and disconnect the male wire to each female wire until a proper connection is achieved, so many fuses can be destroyed each time a trailer is connected. Connecting the wrong wire can also cause the malfunctioning of vital, legally- required automobile 012095:HIS:dld:8~81 2 " 216777S
functions. An organized system for testing and indicating proper connections, without destroying fuses, is needed.
Once connected, the plugs and wires on existing devices are subject to damage. Loose wires may drag on the road or get intermixed with other automobile wires, while the connected wires may be bent or pulled by the trailer movements. The connection may also be exposed to harsh outside environmental elements such as rain, snow, lightening, dirt or flying objects on the roadway.
When docking or launching a boat, the interface may also be submerged in water. An enclosed, water-resistant interface would be extremely advantageous.
U.S. Patent No. 3,970,860, issued to Purdy, discloses a set of relays which operate to connect or isolate different portions of signal light circuits. A trailer signal light adapter circuit is interposed between the automobile circuit and the trailer circuit to give full signal operation at all times. A
relay corresponds to each of the signal light conditions and prevents nonfunctioning lights from being lit.
U.S. Patent No. 4,325,052, issued to Koerner, discloses a trailer light connection system which uses electronic light sensors to detect the light emitted by the automobile. The sensors are connected to circuits equipped with taillight switching devices.
012095: EIIS: dld: 8781 3 U.S. Patent No. 4,781,393, issued to Jeter, discloses a connector box with a six wire plug to be plugged into a socket on an automobile and a six wire socket into which the trailer plug may be attached. If the connector has less than six wires, a jumper is used which has a six prong socket on one end and a three, four or five connection plug on the other end. Each of the hot wires connected from the pickup terminate in a switch wire with a pin upon the end. Each of the trailer wires terminate in a receptacle.
After a set of lights is activated on the automobile, the user must connect the pin into the different sockets until the set of lights are illuminated. Because the wires are fixed, the fuses in this patent are still susceptible to failure.
U.S. Patent No. 5,030,938, issued to Bondzeit, discloses a trailer lighting adapter to connect the lighting systems of American trailers to American or foreign automobiles. The circuitry is powered by the automobile battery but allows negligible current drain from the automobile battery when the battery is not in use. The circuitry is fused or the current is limited to protect the electrical systems from shorts. A light emitting diode indicates a malfunction to the driver.
The foregoing patents indicate that the prior art discloses some of the locator's structures such as plugs, resistors and sockets. The present universal trailer light locator contains important improvements on the prior art to justify differentiation 012095:HIS:dld:8781 4 .
including a connector which can be received into any other connector, a method for testing each connector pin separately and the connection of adjustable non-taillight electrical trailer functions, such as radios, intercoms and microphones.

012095: HIS: dld: 8781 9 ~167~7~
, The twelve (12) volt automobile DC battery 3 distributes voltage across the various electrical components of the automobile 2. Additional wires carry the voltage from the electrical components to the male automobile plug 7. Each prong of the male automobile plug 7 is reciprocally received into the versatile female connector 8 of the input wire 72. The input wire 72 carries the current from the automobile plug 7 into the present invention 16. If one prong of the automobile plug 7 is female, one of the input wires 72 has a versatile male connector 9 which can connect to the female automobile plug 7. The side of the device has a rectangular notch 24 which allows the input wires 72 to enter the plastic casing 16. The output wires 12 are reciprocally received into ninety (90) degree angled female connectors 11. The ninety (90) degree angled female connectors are reciprocally received onto the output connector tabs 74. The open side of the cover 20 allows the angled output wires 12 to exit in parallel with the top of the plastic casing 16 when the cover 20 is closed. The versatile male connectors 10, located on the distal ends of the output wires 12, are reciprocally received into the existing female trailer plug 14.

The versatile male connector 10 is composed of brass and beryllium copper components inside a nylon housing 30. The output wire 12 is reciprocally received into the open flared end 32 of the 012095: HIS: dld: 8781 10 216~'~7S
versatile male connector 10, then crimped inside the central recessed portion of the connector 34 to form an electrical contact.
The opposite end of the connector is composed of a smaller flared end 36 with a brass dowel 38 reciprocally received into the end and protruding out from the end. A symmetrical cross 40 of beryllium copper is evenly folded over the protruding brass dowel with the narrower ends of the cross reciprocally received and soldered into the thick brass ring 42 which encircles the bottom of the brass dowel. The versatile male connector can adapt to any female connector with .140-.200 inch diameter.
The versatile female connector 8 is composed of brass and beryllium copper components inside a nylon housing 50. The output wire 12 is reciprocally received into the open flared end 52 of the versatile female connector 8, then crimped inside the central recessed portion 54 of the versatile female connector 8 to form an electrical contact. The opposite end of the versatile female connector 8- is also flared 56 with four beryllium copper--lead contacts 58 inside of the nylon housing 50. The innermost ends of the lead contacts are anchored 60 around a brass dowel.
