Abstract

An 'N' type plug that is normally used to connect a lighting board on a trailer or the lights on a caravan to the towing vehicle, has been modified so as to test the wiring of the vehicles 'N' type socket. The wiring tester is inserted into the 'N' type socket and the vehicles lights are switched on and off in turn. Three light emitting diodes in the rear of the tester, a panel lamp on top of the tester and a buzzer inside the tester, light up and sound to show the correct operation or malfunction of the wiring upto the 'N' type socket. This tester is easily used and can save considerable time spent in locating faults or in confirming the correct installation of a newly fitted towbar electrics. Also, instead of the person of the towing vehicle having to remember pin allocation's and test each pin individually, they only have to refer to the wiring testers lighting and sounding sequence.

Description

WIRING ALLOCATION TESTER THIS INVENTION RELATES TO A WIRING ALLOCATION TESTER FOR VEHICLE TOWBAR ELECTRICS AND IS MADE UP USING READILY AVAILABLE 'N' TYPE PLUG AND OTHER ELECTRONIC COMPONENTS.
VEHICLES THAT ARE USED TO TOW TRAILERS, BOATS AND CARAVANS ARE ALL FITTED WITH THE APPROPRIATE TOWING BRACKET AND THE ELECTRICAL CONNECTIONS FOR SIDE LIGHTS, STOP LIGHTS, INDICATORS AND FOG LIGHT ARE VIA AN 'N' TYPE SOCKET MOUNTED ON THE REAR OF THE VEHICLES TOWING BRACKET.
THIS WIRING ALLOCATION TESTER IS A MODIFIED 'N' TYPE PLUG THAT IS FITTED INTO THE 'N' TYPE SOCKET AND WHEN THE VEHICLES LIGHTS ARE SWITCHED ON AND OFF IN TURN THE CORRECT OPERATION OR MALFUNCTION OF THE CIRCUIT IS INDICATED BY THE LIGHT EMITTING DIODES, BUZZER AND PANEL LAMP FITTED INTO THE WIRING TESTER.
WHEN A TRAILER, BOAT OR CARAVAN IS HOOKED-UP TO A VEHICLE THE LIGHTS ARE SWITCHED ON AND OFF IN TURN TO CONFIRM THAT THE LIGHTS ARE OPERATING CORRECTLY. IF THERE IS A MALFUNCTION IN THE LIGHTING SYSTEM MOST PEOPLE THINK 'IS IT THE VEHICLES WIRING AT FAULT OR WHAT'! THE WIRING ALLOCATION TESTER ALLOWS THE VEHICLES 'N' TYPE SOCKET TO BE CHECKED TO CONFIRM IT'S CORRECT OPERATION. THIS ALLOWS THE VEHICLE'S DRIVER TO CONCENTRATE THEIR EFFORTS TO LOCATE THE FAULT ON THE LIGHTING BOARD OR REAR LIGHT'S.
THE WIRING ALLOCATION TESTER ALSO ALLOWS ANYONE INVOLVED IN THE FITTING OF TOWING BRACKETS TO CONFIRM THE CORRECT ALLOCATION AND OPERATION OF THE WIRING THAT THEY HAVE CARRIED OUT.
THE WIRING ALLOCATION TESTER HAS SEVEN PINS AS SHOWN IN FIGURE 2. FOUR OF THESE PINS ARE ISOLATED FROM EACH OTHER WITH DIODES.
TWO OF THESE PINS GO TO TWO RED L.E.D'S AND FOUR PINS TO THE GREEN L.E.D., BUZZER AND PANEL LAMP VIA THE DIODES. THE L.E.D'S ARE EARTHED THROUGH TWO RESISTORS TO THE SEVENTH PIN. IT IS THE WAY THAT THE L.E.D'S , DIODES AND RESISTORS ARE CONNECTED AS IN FIGURE 4, THAT ALLOWS EACH CIRCUIT TO BE CHECKED WITHOUT INTERFEARING WITH THE OTHER. THE BUZZER SOUNDS WITH THE FOG LIGHT, INDICATORS AND STOP LIGHTS. THE PANEL LAMP LIGHTS UP WITH THE GREEN L.E.D. BUT IS ONLY USED TO DRAW ENOUGH CURRENT FOR THE TOWING VEHICLES AUDIBLE INDICATIOR RELAY TO SOUND.
WIRING ALLOCATION TESTER DETAIL'S OF PIN ALLOCATION'S, WIRE COLOUR'S, CIRCUIT DIAGRAM AND COMPONENT'S USED, AS WELL AS DETAIL'S OF THE CORRECT STATE OF THE L.E.D'S FOR EACH LIGHTING CIRCUIT--ARE-AS LISTED BELOW.
FIGURE 1 IS A DRAWING OF THE SIDE ELEVATION OF AN 'N' TYPE PLUG AS USED ON TRAILER/BOAT LIGHTING BOARDS AND CARAVANS IN THE U.K.
FIGURE 2 SHOWS A DRAWING OF THE FRONT ELEVATION OF AN 'N' TYPE PLUG WITH THE PIN NUMBERS AND THE USUAL WIRING CODE.
FIGURE 3 IS A DRAWING OF THE REAR ELEVATION OF AN 'N' TYPE PLUG WITH 3 LIGHT EMITTING DIODES FITTED TO.SHOW THE CORRECT OPERATION OR MALFUNCTION OF THE LIGHTING BOARD OR CARAVAN.
FIGURE 4 IS A CIRCUIT DIAGRAM OF THE WIRING ALLOCATION TESTER ALONG WITH PIN NUMBERS AND ALLOCATIONS.
FIGURE 5 IS A COMPONENT LIST FOR EACH INDIVIDUAL WIRING ALLOCATION TESTER FIGURE 6 IS A TABLE SHOWING THE STATE OF THE LIGHT EMITTING DIODES FOR THE CORRECT OPERATION OF EACH LIGHTING CIRCUIT.

Claims (4)

  1. WIRING ALLOCATION TESTER
    CLAIM'S 1 AN 'N' TYPE PLUG THAT HAS BEEN MODIFIED WITH ELECTRONIC COMPONENTS AS IN FIGURE'S 3,4, & 5, IN ORDER TO TEST THE CORRECT ALLOCATION AND OPERATION OF WIRING TO AN 'N' TYPE SOCKET FITTED TO A VEHICLE'S TOWING BRACKET.
    2 AN 'N' TYPE PLUG THAT HAS BEEN MODIFIED WITH ELECTRONIC COMPONENTS AS IN FIGURE'S 3,4, & 5, IN ORDER TO HELP LOCATE FAULT'S WHEN LIGHTING BOARDS AND CARAVAN REAR LIGHT'S DO NOT FUNCTION PROPERLY WHEN HOOKED-UP TO A VEHICLE.
    3 AN 'N' TYPE PLUG THAT HAS BEEN MODIFIED WITH ELECTRONIC COMPONENTS AS IN FIGURE'S 3,4, & 5, IN ORDER TÒ HELP IN THE CORRECT ALLOCATION AND OPERATION OF WIRING TO AN 'N' TYPE SOCKET DURING INSTALLATION.
    Amendments to the claims have been filed as follows WIRING ALLOCATION TESTER CLAIMS 1 AN 'N' TYPE PLUG THAT HAS BEEN MODIFIED WITH ELECTRONIC COMPONENTS AS IN FIGURES 3,4, & 5 IN ORDER TO TEST THE CORRECT OPERATION OF WIRING TO AN 'N' TYPE SOCKET FITTED TO A VEHICLES TOWING BRACKET WITHOUT THE VEHICLE HAVING TO BE CONNECTED TO THE TRAILER OR CARAVAN IN ORDER FOR THE TESTER TO GIVE AN INDICATION.
  2. 2 AN 'N' TYPE PLUG THAT HAS BEEN MODIFIED WITH ELECTRONIC COMPONENTS AS IN FIGURES 3,4, & 5 IN ORDER TO HELP LOCATE FAULTS WHEN LIGHTING BOARDS AND CARAVAN REAR LIGHTS DO NOT FUNCTION PROPERLY WHEN HOOKED UP TO-A VEHICLE. THE TESTER ALLOWSFOR THE TESTING OF CIRCUITS WITHOUT REQUIRING AN ASSISTANT OR EXTENSION LEAD AS AN IN BUILT BUZZER SOUNDS TO INDICATE THAT POWER IS REACHING THE PINS IN THE 12'N' SOCKET FOR INDICATORS, FOG LIGHTS, AND BRAKE LIGHTS. ONLY THE TWO LIGHT EMITTING DIODES FOR THE SIDE LIGHTS HAVE TO BE CHECKED MANUALLY BY THE PERSON TESTING THE CIRCUITS.
  3. 3 AN 'N' TYPE PLUG THAT HAS BEEN MODIFIED WITH ELECTRONIC COMPONENTS AS IN FIGURES 3,4, & 5 IN ORDER TO HELP IN THE CORRECT ALLOCATION AND OPERATION OF WIRING TO AN 'N' TYPE SOCKETDURING INSTALLATION. THE TESTER ALLOWS THE PERSON INSTALLING THE WIRING TO CHECK THE CORRECT OPERATION OF AN AUDIBLE INDICATOR RELAY AND THIS IS ACHIEVED BY THE PANEL LAMP THAT IS MOUNTED ON THE TESTER. PREVIOUSLY A LIGHTING BOARD WOULD HAVE HAD TO BE CONNECTED TO TEST THE CORRECT OPERATION OF AN AUDIBLE INDICATOR RELAY.
  4. 4 THIS TESTER IS DESIGNED TO USE ONLY THREE LIGHT EMITTING DIODES TO INDICATE THE OPERATION OF SIX LIGHTING CIRCUITS.
    PREVIOUS DESIGNS HAVE USED ONE LIGHT EMITTING DIODE FOR EACH CIRCUIT TO BE MONITORED.
