00 Patent Application Comolete Soecification -Liaht Emittina Diode Safety Trailer Connector Inventor: Dennis Ronald Gravolin 271 River Street Maclean NSW 2463 Ph: (02) 66452722 Fax: (02) 66452723 Email: [email protected] Patent Application Complete Specification 0 0 Light Emitting Diode Safety Trailer Connector Introduction to the Invention There are many trailer connectors on the market today to supply electrical o0 connections from a hauling vehicle to a towed trailer. These connectors 0 are simple in design, construction and operation. They consist of a plastic CN1 n molded plug housing, connector pins and terminations so the connector 0 O can be attached to either the wiring of the vehicle or the trailer, depending on which connection type is used. The single purpose of the connector is to provide a reliable electrical connection between the vehicle and trailer for each trailer circuit, whether it is lighting or auxiliary circuits. However, research has found that in all of the common trailer connectors on the market, this connection is not reliable. This is due to connector pins closing and not making contact, therefore making a trailer circuit faulty. The only way to test a faulty trailer connector is to pull the connector out of the mating connector and test each individual pin to determine if there is power getting to the pin. This can be time consuming and costly.
The invention as described here in titled, "Light Emitting Diode Safety Trailer Connector" allows instant and automated diagnosis of trailer connector circuits within a common trailer connector. An array of Light Emitting Diode's (LEDs), protrude from the body of the trailer connector so they are visible. The protruding array of LEDs have different colours which represent each different trailer circuits. The LEDs illuminate when power is present at the connector. When no power is getting to the connector due to faulty connector pins or some other fault condition, the LED for that circuit will not illuminate giving instant indication that there is no power getting to Complete Specification Light Emitting Diode Safety Trailer Connector Sthe connector. This all happens when the connector is mated to a
O
O partnering connector so there is no need to pull the plug out and test (Ni individual connections manually. The connector can be diagnosed whilst in Soperation. The design, of the Light Emitting Diode Safety Trailer Connector is able to be manufactured as any existing or purpose designed trailer connector, male or female, plug or socket or adapter. A female or socket oo Light Emitting Diode Safety Trailer Connector can be mated with a male or
O
plug Light Emitting Diode Safety Trailer Connector and both will work and
O
ct] show the condition of power through the connection. The invention is not a O 10 tester nor is aimed as being a diagnostic only device. The invention adds a novel safety feature to existing trailer connectors.
