Abstract

In an aspect, a kit of parts for an electrical connector, which includes a plurality of housing portions, a first male terminal and a second male terminal, and an output device. The plurality of housing portions are mateable together to form a housing. The printed circuit board positionable in the housing. The male terminals are connected to the printed circuit board and are positioned to connect to an electrical power source. The output device is connected to the printed circuit board. The printed circuit board is connectable to an electrical conduit and is configured to electrically connect the electrical conduit to the male terminals, and contains a microprocessor that is programmed to indicate via the output device at least one property of a circuit formed with the electrical connector and the electrical power source.

Claims

1. A kit of parts for an electrical connector, comprising:

a plurality of housing portions that are matable together to form a housing having a shape that is connectable to a D-tap connector from an electrical power source;

a first male terminal and a second male terminal that are positionable in the housing to connect the electrical power source to the electrical conduit when the housing is connected to the D-tap connector from an electrical power source;

a current flow preventer located between the first and second male terminals and electrical conduit and inside the housing, and positioned to prevent current flow through the electrical conduit when the polarity at the male terminals is other than a selected polarity;

an output device configured to indicate whether the polarity at the male terminals is other than the selected polarity; and

a printed circuit board positionable in the housing,

wherein the male terminals are connected to the printed circuit board,

and wherein the output device is connected to the printed circuit board, wherein the printed circuit board is connectable to the electrical conduit and is configured to electrically connect the electrical conduit to the male terminals, and contains a microprocessor that is programmed to control the output device to indicate whether the polarity at the male terminals is other than the selected polarity.

2. A kit of parts as claimed in claim 1, wherein the output device is a light-emitting diode (LED).

3. A kit of parts as claimed in claim 1, wherein the output device is a multicolour light-emitting diode (LED).

4. A kit of parts as claimed in claim 1, wherein the microprocessor is programmed to indicate via the output device at least one condition selected from a group of conditions consisting of:

whether the voltage at the first and second male terminals is above a selected maximum permitted voltage, whether the voltage at the first and second male terminals is below a selected minimum permitted voltage, whether the voltage at the first and second male terminals is within a selected range of permitted voltages, whether the current is above a selected permitted current, and whether the temperature in the circuit is above a selected maximum permitted temperature.

5. A kit of parts as claimed in claim 4, wherein the microprocessor is programmed to prevent current flow between the male terminals and the electrical power source based on a determination by the microprocessor of at least one condition selected from the group of conditions consisting of:

whether the voltage at the first and second male terminals is above a selected maximum permitted voltage, whether the voltage at the first and second male terminals is below a selected minimum permitted voltage, whether the current is above a selected maximum permitted current and whether the temperature in the circuit is above a selected maximum permitted temperature.

6. A kit of parts as claimed in claim 5, wherein the selected minimum permitted voltage is a first selected minimum permitted voltage that is indicative of an undervoltage condition, and wherein the microprocessor is further programmed to indicate via the output device if the sensed voltage is below a second selected minimum permitted voltage, to notify a user that an undervoltage condition is approaching.

7. A connector assembly, comprising:

a plurality of housing portions mated together to form a housing shaped to connect to a D-tap connector from an electrical power source;

an electrical conduit that extends from the housing, wherein the electrical conduit is connectable directly to an electrical device;

a first male terminal and a second male terminal positioned in the housing to connect the electrical power source to the electrical conduit when the housing is connected to the D-tap connector from the electrical power source; and

a current flow preventer located between the first and second male terminals and electrical conduit and inside the housing, and positioned to prevent current flow through the electrical conduit if the polarity at the male terminals is other than a selected polarity;

a printed circuit board positioned in the housing,

an output device connected to the circuit board and configured to indicate whether the polarity at the male terminals is other than the selected polarity; and

wherein the male terminals are connected to the printed circuit board,

and wherein the output device is connected to the printed circuit board, wherein the printed circuit board is connectable to an electrical conduit and is configured to electrically connect the electrical conduit to the male terminals, and contains a microprocessor that is programmed to control the output device to indicate whether the polarity at the male terminals is other than the selected polarity.
