DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(4) FIG. 1 shows a conventional electrical system 10 for a boat. The system has a battery 12 that is electrically coupled to a circuit protection 15 by a pair of wires for carrying a direct-current (DC) power signal to the circuit protection 15. The circuit protection 15 is electrically coupled to various loads 18, such as lights, pumps, motors, or other electrical equipment that may be used on the boat. The circuit protection 15 passes current of the power signal through a plurality of fuses for distribution of power to the loads 18. The circuit protection 15 is also electrically coupled to a conventional fish finder 22 that is configured to find fish and display the locations of the fish, as described above.

(5) The loads 18 may draw power from the battery 12 through the circuit protection 15 in a sporadic manner causing fluctuations in the current and voltage of the power signal provided to the fish finder 22. These fluctuations at the input of the fish finder 22 are exacerbated by the fact that power delivered to the loads of the boat, including the fish finder 22, share the same electrical conduit, such as the same bus or cable connecting the circuit protection 15 to the battery 12. Further, over time, the voltage and/or current output by the battery 12 may decrease as the energy in the battery 12 is depleted. Moreover, the fluctuations in the power signal can adversely affect the performance of the fish finder 22. In some cases, the power delivered to the fish finder 22 can undesirably fall below the power specifications of the fish finder 22. As a result of the fluctuations, the image displayed by the fish finder 22 can become distorted making it more difficult for a user to identify or locate fish based on the image.

(6) In addition, the distortions and performance problems of the fish finder 22 caused by the power fluctuations may be transient, depending on the current levels drawn by other loads 18 of the boat and the level of energy remaining in the battery 12, making it difficult determine the source of the problem or making performance of the fish finder 22 unpredictable.

(7) FIG. 2 depicts an exemplary electrical system 30 that powers a fish finder 22 through an electrical connection that bypasses the circuit protection 15. Although the figure demonstrates use with a fish finder, the invention is not limited in scope to this single component.

(8) In the embodiment show by FIG. 2, the fish finder 22 is electrically coupled to the battery 12 through a separate cable system 33 that is not used for power the other loads 18. The cable system 33 of FIG. 2 comprises a switch 41, filter 42, and regulator 43 that are electrically and serially connected to each other by wires. As an example, each component of the cable system 33 may be connected to the next electrical component by a pair of wires (or other numbers of wires) that are bound within a cable. Thus, a power signal from the battery 12 passes through the cable system 33 for powering the fish finder 22 via an electrical path that bypasses the circuit protection 15. If desired, the cable system 33 may be electrically coupled to the same battery terminals as the circuit protection 15.

(9) Since the fish finder 22 is connected to the battery 12 via an electrical path that bypasses the circuit protection 15, fluctuations in the power signal received by the fish finder 22 should be less pronounced. In addition, as will be described in more detail below, the cable system 33 includes components that help to reduce or mitigate the fluctuations so that a more stable power signal is provided to the fish finder 22.

(10) In this regard, the filter 42 is configured to filter fluctuations in the power signal to provide an output that is smoother and more stable relative to the power signals distributed by the circuit protection 15 to the loads 18. Further, the regulator 43 is configured to regulate the voltage and current of the received power signal to provide an output that has substantially constant current and voltage. As an example, the regulator 43 may be implemented by a DC-to-DC converter that is configured to receive a DC signal and output a DC signal at a constant voltage and current. Notably, the DC-to-DC converter outputs a substantially constant voltage and current event when the input of the DC-to-DC converter fluctuates.

(11) The switch 41 is configured to transition between an open circuit state and a short circuit state based on manual input by a user. During operation of the fish finder 22, the switch 41 may be controlled to be in the short circuit state, thereby providing a short circuit for current to pass. When operation of the fish finder 22 is no longer desired, the user may control the switch 41 to transition it to the open circuit state so that the fish finder 22 is electrically isolated from the battery 12. In the open circuit state, the switch 41 prevents the fish finder 41 from drawing current from the battery 12, thereby conserving the energy within the battery 12 for other uses. This may be desirable since the fish finder 22 may continue to draw a small amount of current even when turned off. If desired, the cable system 33 may include in-line fuses (not shown) to help prevent unusually high voltages or currents.

(12) The filter 42 and regulator 43 help to suppress fluctuations in the power signal caused by the loads 18 and other factors so that a stable power signal having a relatively constant voltage and current is provided to the fish finder 22. In addition, the regulator 43 can be specifically designed to provide a constant output power that satisfies the power specifications of the fish finder 22. As a result, the fish finder 22 should receive a power signal that is more stable and consistent with its power requirements so that the operation and performance of the fish finder 22 is less affected by the loads 18. Specifically, since the cable system 33 eliminates or reduces fluctuations in the power signal delivered to the fish finder 22, the image displayed by the fish finder 22 should be less distorted relative to the embodiment shown by FIG. 1.

(13) If desired, existing boats having the electrical system 10 shown by FIG. 1 can be easily retrofitted to provide the system 30 shown by FIG. 2. In this regard, the fish finder 22 of FIG. 1 may be disconnected from the circuit protection 15 and connected to the battery 12 using the cable system 33, as shown by FIG. 2. Addressing the performance issues of the fish finder 22 in this manner may be considerably less expensive than other possible solutions.

(14) As an example, it is possible to alleviate the performance issues of the fish finder 22 of FIG. 1 by adding more batteries 12 to provide more power through the circuit protection 15. However, the cost of adding more batteries or upgrading the battery 12 to provide more power is likely much greater than the cost of the components of the cable system 33.

(15) As generally understood and demonstrated in FIG. 3, system 50 of the present invention has a first closed end lug 52 and a second closed and lug 54 constructed and arranged for connection to a primary electrical source. In a marine vessel, all-terrain vehicle, or conventional motor vehicle this would be the main battery. In one preferred embodiment, these lugs are provided as connected to wire in a standard for the diameter (gauge) of round drawn wire, being the American Wire Gauge (AWG) as 4 AWG. The size is commonly known as the smallest AWG size is 40 and the largest is 0000. A 4 AWG is known to be 21.2 mm diameter.

(16) First closed end lug 52 is connected to first multi conductor cable wire 56. One preferred body meant first multi conductor cable wire 56 is provided having a cable weight of 230 LBs/MFT.

(17) First closed end lug 54 also has this cable wire but is split in two as demonstrated in FIG. 3 with each individual wire connected to a first blade fuse 58 and a second blade fuse 60. Each of the first blade fuse 58 and second blade fuse 60 in a preferred embodiment are 20-amp fuses. Cable wire exits each of the first blade fuse 58 and second blade fuse 60 and is connected to first hand lock connector 62 and second hand lock connector 64.

(18) In a preferred environment, each a first hand lock connector 62 and second hand lock connector 64 are available commercially under the brand-name Posi-lock®.

(19) Exiting each of first hand lock connector 62 and second hand lock connector 64 are first cable 68 and second cable 69. Each of these cables are constructed and arranged to be identical to first multi conductor cable wire 56.

(20) As demonstrated in the FIG. 3, the four cables are encased in cover 70. Emanating outward from cover 70 are first exit cover 72 and second exit cover 78. As can be seen in FIG. 3, first outlet cover 72 has first multi conductor cable wire 56 contained therein and second exit cover 78 contains the combined are first cable 68 and second cable 69.

(21) First multi conductor cable wire 56 is ultimately split into two separate wires and terminates in first terminating hand lock connector 74 and second terminating hand lock connector 76.

(22) Extending from second exit cover 78 is first cable 68 and second cable 69 that ultimately terminate in third terminating hand lock connector 86 and fourth terminating hand lock connector 84 respectively as shown FIG. 3.

(23) The system of the invention provides novel advancements over any currently known or used system in the following areas: A) Multiple fish finders and accessories can be provided sufficient, clean power on one wiring harness; B) Multiple speakers and amplifiers can be provided sufficient, clean power on one wiring harness; C) The hand lock or Posi-Lock® connectors allow for an easy, non-crimp application that erases the potential for voltage drop and corrosion; D) Every part of the harness is made with copper tinned coated wire and connectors to eliminate possibilities for corrosion in any outdoor or marine environment including salt water; E) First and only harness made to allow for a single pull application thru a vessel, atv, or vehicle to power marine electronics, electrical accessories, amplifiers and speakers; F) The harness is made with sufficient wire strands to carry power to marine electronics and accessories over a 26-foot run; G) Harness allows one to bypass bus bars while still being able to distribute adequate, clean power to multiple marine electronics and/or amplifiers and speakers; H) Harness increases battery life of cranking battery by preventing multiple electronics from draining cranking batteries down too far and causing failure in 6-8 months.
