Description

BACKGROUND

Conventionally, a towed vehicle may be connected to a towing vehicle in order to operate the various driving lights or signals on the towed vehicle such as the brake lights, the tail and license lights, the turn signals, and various external lighting. In some known examples, a trailer connection cord may extend from the towed vehicle and connect to the towing vehicle via a pair of connectors in order to provide the driver of the towing vehicle the capabilities of operating the various driving lights/signals on the towed vehicle. In addition, when coupled to the towed vehicle, the towing vehicle may power or charge a battery located on the towed vehicle via the trailer connection cord.
However, conventional mechanisms do not allow someone to operate some of the components on the towed vehicle (e.g., the external lighting) when the trailer connection cord is not connected to the towed vehicle. In one example, the towed vehicle may be a camper trailer that is towed by an automobile. However, when the camper trailer is located at a campsite, the camper trailer is not necessarily connected to the towing vehicle and, therefore, is prevented from illuminating the external lighting on the camper trailer.
In addition, individuals such as campers may find themselves in a situation where an electrical power source is not available. For example, typically, when a camper trailer is located at a campsite, the campsite provides an electrical outlet where a power cord of the camper trailer can be connected. This electrical power source may provide electrical power to the electrical panel of the camper trailer, which activates the power outlets and other components on the camper trailer. However, if the camper trailer is not connected to an electrical power source, the electrical power on the camper trailer is limited to a small subset of components by using energy supplied from its battery. However, a camper may find themselves in a position which he/she requires a power source such as a 12-volt power source in order to power or charge an external device.

DETAILED DESCRIPTION

The embodiments provide a connector device that is configured to be coupled to a connection cord of a first vehicle (e.g., a towed vehicle), and the connector device is configured to provide access to a power source (e.g., battery) included within the first vehicle. The connection cord may extend from the outside of the first vehicle and be designed to connect to a second vehicle (e.g., towing vehicle) for purposes of operating the driving signals (e.g., brake light, tail light, etc.) on the first vehicle.
In one example, when the connector device is coupled to the connection cord, the connector device may re-route electrical power back to the first vehicle in order to activate one or more components on the first vehicle such as the exterior lighting that is originally designed to be illuminated at nighttime when the first vehicle is being towed on a roadway. The connector device may allow someone to activate (e.g., turn off and on) these external lights without the connection cord being connected to the second vehicle.
In another example, the connector device may provide access to the internal battery source on the first vehicle for charging or powering an external device such as a phone, smartphone, computer, laptop, tablet, or generally any type of computing device requiring electrical power. For example, the connector device may be coupled to the connection cord of the first vehicle, and the external device may be coupled to the connector device. In this manner, the connector device may be configured to charge or power the external device by tapping into the power source of the first vehicle. As such, even if an electrical hook up is not available to the first vehicle, the connector device may provide access to a power source (e.g., 12-volt power source) that otherwise is not available for such use.
In addition, the connector device may include a housing that is adaptable to a cord-end connector of the connection cord in a manner that ensures the connector device is properly coupled to the cord-end connector. For example, the cord-end connector may include an arrangement of various connectors (e.g., male or female electrical terminals) such as a connector for the brake light, a connector for the tail and license lights, a connector for the battery charge, and connectors for the left/right turn/stop signals, etc. As indicated above, conventionally, the cord-end connector is coupled to a vehicle-end connector of the second vehicle (e.g., the towing vehicle) for purposes of towing the first vehicle on the road.
However, instead of connecting the cord-end connector of the connection cord to the vehicle-end connector of the second vehicle, the connector device is coupled to the cord-end connector of the connection cord in a manner that ensures the connectors of the cord-end connector are properly aligned with one or more connectors of the connector device in order to provide access to the power supply on the first vehicle without a person having any kind of knowledge of the connector arrangement of either the cord-end connector or the connector device. In addition, the connector device may include a switching unit that is designed to activate the access to the power source on the first vehicle in order to re-route electrical power to the component(s) on the first vehicle itself and/or power or charge an external device connected to the connector device. These and other features are further explained with reference to the figures.
FIG. 1A illustrates a system 100A having a first vehicle 102 that is connected to a second vehicle 114 via a connection cord 120 for towing the first vehicle 102 on a roadway. The first vehicle 102 may be any type of vehicle capable of being towed that also includes a power source 112. Throughout the disclosure, the first vehicle 102 may be sometimes referred to as a towed vehicle. In some examples, the first vehicle 102 may be a camper, camper trailer, recreational vehicle, trailer, popup camper, or camper shell. In some examples, the first vehicle 102 may be a vehicle that is not capable of being independently driven on the roadway. For example, the first vehicle 102 may not be a self-powered vehicle capable of driving on the roadway unassisted.
The second vehicle 114 may be any type of vehicle capable of towing the first vehicle 102. Throughout the disclosure, the second vehicle 114 may be sometimes referred to as a towing vehicle. In some examples, the second vehicle 114 may be an automobile, jeep, truck, tractor-trailer, recreational vehicle, or generally any type of vehicle capable of independently driving on the roadway, e.g., an automobile.
As shown in FIG. 1A, in order to tow the first vehicle 102 on the roadway, the first vehicle 102 may be connected to the second vehicle 114 via the connection cord 120. The connection cord 120 may connect the first vehicle 102 and the second vehicle 114 for purposes of operating the required driving signals/lights of the first vehicle 102 on the roadway. For example, the first vehicle 102 may include brake lights 104, tail and license lights 106, turn signals 108, and/or external lighting 110. The first vehicle 102 may include other types of lighting/signals that may be required or beneficial for being towed on the roadway.
The first vehicle 102 may also include a power source 112 that is capable of being charged when connected to the second vehicle 114 via the connection cord 120. The power source 112 may be any type of power source located on the first vehicle 102. In one example, the power source 112 may be a battery for supplying power to one or more components of the first vehicle 102 when the first vehicle 102 is not connected to an external power hook-up or connected to the second vehicle 114. In one specific example, the power source 112 may provide electrical power to lights included within the first vehicle 102. In one example, the power source 112 may be a battery providing a 12-volt power source.
By coupling the connection cord 120 to the second vehicle 114, a driver of the second vehicle 114 may operate the various driving signals/lights included on the first vehicle 102 (e.g., the brake lights 104, the tail and license lights 106, the turn signals 108, the external lighting 110, etc.), as well as charge the power source 112 of the first vehicle 102. Also, the first vehicle 102 may be secured to the second vehicle 114 via any type of known towing mechanisms that permit the first vehicle 102 to be securely connected to the second vehicle 114 when driving on the roadway.
The connection cord 120 may include a cord-end connector 116 that is designed to be coupled to a vehicle-end connector 118 located on the second vehicle 114. For example, the connection cord 120 may extend from the first vehicle 102, and the cord-end connector 116 may be disposed on an end of the connection cord 120. As such, a person may couple the cord-end connector 116 to the vehicle-end connector 118 of the second vehicle 114. The cord-end connector 116 may include a plurality of connectors (e.g., connectors 362 shown in FIG. 3F) that are arranged in a manner to be coupled to corresponding connectors of the vehicle-end connector 118 in order to allow for the correct signals to be supplied to the correct driving components of the first vehicle 102 as well as the charging of the power source 112. Accordingly, the connection cord 120 may include a plurality of internal wires (e.g., internal wires 119 shown in FIG. 1B) that extend to the appropriate components on the first vehicle 102 or an intermediate component (e.g., an electrical relay, electrical panel) on the first vehicle 102, which then supplies the signals to the appropriate components. The other ends of the internal wires 119 are extended to the connectors of the cord-end connector 116.
FIG. 1B illustrates a system 100B depicting the cord-end connector 116 of the connection cord 120 being coupled to a connector device 126, according to an embodiment. For example, the connector device 126 may be configured to be coupled to the cord-end connector 116 of the connection cord 120 of the first vehicle 102, and the connector device 126 may be configured to provide access to the power source 112 included on the first vehicle 102. As indicated above, the connection cord 120 may be designed to be connected to the second vehicle 114 for purposes of towing the first vehicle 102. However, instead of coupling the connection cord 120 to the vehicle-end connector 118 of the second vehicle 114, the connector device 126 may be coupled to the cord-end connector 116 of the connection cord 120. The connector device 126 may be configured to allow access to the power source 112 on the first vehicle 102 that is otherwise not accessible in most situations.
In one embodiment, the connector device 126 may be configured to re-route electrical power from the power source 112 to the first vehicle 102 for activating one or more components 122 on the first vehicle 102. The one or more components 122 may include the external lighting 110. For example, the external lighting 110 may be one or more lights located on an outside of the first vehicle 102. Conventionally, a driver of the second vehicle 114 may activate the external lighting 110 (or may be automatically activated) when driving during the night or dusk so that other drivers may easily see the first vehicle 102 that is towed by the second vehicle 114. However, when the connection cord 120 is not connected to the second vehicle 114, a person has virtually no way of illuminating the external lighting 110. According to one embodiment, after the connector device 126 is coupled to the cord-end connector 116 of the connection cord 120, the external lighting 110 may be activated by operating the connector device 126 (e.g., flipping a switch), which then re-routes the electrical power back to the first vehicle 102 via the connection cord 120 such that the external lighting 110 is illuminated.
As indicated above, the connection cord 120 may extend from the first vehicle 102, and the cord-end connector 116 may be located on the end of the connection cord 120. The cord-end connector 116 may include connectors that are directly or indirectly connected to one or more internal wires 119 that extend along at least the length of the connection cord 120. One or more of these internal wires 119 may be associated with the power source 112. As such, the internal wire 119 associated with the power source 112 may extend further into the first vehicle 102 and may be connected to the power source 112. Alternatively, the internal wire 119 associated with the power source 112 may be connected to one or more intermediate components (e.g., an electrical panel, or other type of electrical relay) which then provides a connection to the power source 112. As such, the connection cord 120 includes at least one internal wire 119 that directly or indirectly provides a connection to the power source 112.
Typically, this power source connection is used for charging the power source 112 by the second vehicle 114 when the connection cord 120 is coupled to the second vehicle 114. For example, this power source connection is not originally designed to supply electrical power, but rather to receive it from the second vehicle 114 for purposes of charging the power source 112. As such, the power source 112 is originally designed to be a power source within the actual first vehicle 102—not supplying electrical power via the connection cord 120.
However, the connector device 126 may be coupled to the cord-end connector 116 of the connection cord 120 in a manner that connects the internal wire 119 corresponding to the power source 112 to another internal wire 119, or more generally, provides access to the internal wire 119 corresponding to the power source 112. Because this connection to the power source 112 is active (e.g., the internal wire 119 is an active line at all times or most times), when coupled, the connector device 126 may actually receive electrical power from the power source 112 via the connection cord 120. Then, the connector device 126 may be configured to re-route the electrical power received from the connector associated with the internal wire 119 corresponding to the power source 112 back to the first vehicle 102 along a different internal wire 119 of the connection cord 120 that may be at least indirectly connected to the external lights 110, for example.
In this context, the connector device 126 may provide one or more bridges (or connection points) between the connector of the cord-end connector 116 that is associated with the power source 112 and the connector(s) of the cord-end connector 116 that is associated with one or more components 122 such as the external lights 110. As further explained with reference to FIG. 2, the bridges or connections points associated with the connector device 126 may be connectors and/or switches. Therefore, the connector device 126 may be configured to receive electrical power from the power source 112 via the connection cord 120, and then re-route the electrical power back to the first vehicle 102 for activating the one or more components 122 on the first vehicle 102.
According to another embodiment, the connector device 126 may be configured to be coupled to at least one external device 128. The external device 128 may include a phone, smartphone, computer, laptop, tablet, or generally any type of device requiring electrical power. For example, the connector device 126 may be configured to be directly or indirectly coupled to the external device 128 via a standard power cord associated with the external device 128, for example. The connector device 126 may be configured to power or charge the external device 128 based on the provided access when coupled to the external device 128 and the cord-end connector 116 of the connection cord 120. For example, the connector device 126 may provide one or more bridges (or connection(s)) between the internal wire 119 or connector of the cord-end connector 116 that is associated with the power source 112 and a connector interface unit, disposed on the connector device 126, that is configured to connected to the external device 128. These features are further explained with reference to FIG. 2.
FIG. 2 illustrates the connector device 126 according to an embodiment. The connector device 126 may include a housing 131, a plurality of connectors 132, a switching unit 130, and at least one connector interface unit 133. The housing 131 may be configured to enclose the plurality of connectors 132 and may be configured to at least partially enclose the switching unit 130. The housing 131 may have a shape that is designed to correspond to a housing associated with the cord-end connector 116 to ensure that one or more connectors 132 of the connector device 126 properly align with connectors 117 of the cord-end connector 116. In one example, the housing 131 may be designed to be coupled with the housing of the cord-end connector 116 such that the fit between these two housing may occur when the housing 131 is orientated in a specific way with respect to the housing of the cord-end connector 116.
The plurality of connectors 132 may include a first connector 132-1, a second connector 132-2, a third connector 132-3, and a fourth connector 132-4. The connectors 132 are configured to be coupled to the connectors 117 of the cord-end connector 116. However, it is understood that the number of connectors 132 illustrated in FIG. 2 is merely an example for explanatory purposes, where the embodiments may encompass any number of connectors 132 such as any integer greater or equal to two. In some examples, the number of connectors 132 may match the number of connectors 117 on the cord-end connector 116 of the connection cord 120. For example, if the cord-end connector 116 of the connection cord 120 is a 7-way connector, the connectors 132 may include seven connectors 132 to match the cord-end connector 116. In this example, the cord-end connector 116 includes a first connector 117-1, a second connector 117-2, a third connector 117-3, and a fourth connector 117-4, each of which corresponds to a specific connector 132 of the connector device 126. In other examples, the number of connectors 132 does not necessarily have to match the number of connectors 117 on the cord-end connector 116. For example, the number of connectors 132 may be greater than or less than the number of connectors 117 on the cord-end connector 116.
In some examples, the connectors 132 may be male connectors having electrical terminals that are configured to be received by female connectors 117 of the cord-end connector 116. In other examples, the connectors 132 may be female connectors having recesses with electrical terminals located within the recesses in order to receive the male connectors 117 of the cord-end connector 116. In either case, the connectors 132 of the connector device 126 may be coupled to the connectors 117 of the cord-end connector 116 in manner that properly couples them together.
In one non-limiting example, the first connector 132-1 may be associated with the power source 112, the second connector 132-2 may be associated with a first component 122-1 such as the external lighting 110, the third connector 132-2 may be associated with a second component 122-2 such as the tail and license lights 106, and the fourth connector 132-4 may be associated with the external device 128. Therefore, when the connector device 126 is coupled to the connectors 117 of the cord-end connector 116 of the connection cord 120, the housing 131 of the connector device 126 is designed to ensure that the connector 117-1 of the cord-end connector 116 associated with the power source 112 connects to the first connector 132-1, the connector 117-2 of the cord-end connector 116 associated with the external lighting 110 connects to the second connector 132-1, and the connector 117-3 of the cord-end connector 116 associated with the tail and license lights 106 connects to the third connector 132-3. However, it is noted that besides the first connector 132-1 associated with the power source 112, the other connectors 132 may be associated with other types of components 122 (e.g., the brake lights 104, turn signals 108, etc.) so long as the connection cord 120 provides an internal wire 119 back to the first vehicle 102.
The connector interface unit 133 may be any type of electrical component configured to allow the external device 128 to be connected to the connector device 126. For example, the connector interface unit 133 may be adapted to connect to the external device 128 directly or via a power cord. In one example, the connector interface unit 133 may be configured to receive a power cord associated with the external device 128 via a USB or standard two-prong electrical socket. In one example, the fourth connector 132-4 may be connected to the connector interface unit 133. In another example, the fourth connector 132-4 is simply omitted. Although one connector interface unit 133 is illustrated in FIG. 2, the connector device 126 may include multiple connector interface units 133 in order to power or charge multiple external devices 128 at the same time.
The switching unit 130 may include one or more switches designed to create an open circuit and/or provide one or more connections between the first connector 132-1 associated with the power source 112 and one or more other connectors 132 (and/or the connector interface unit 133). The switching unit 130 may be connected to some or all the connectors 132. In the example of FIG. 2, the switching unit 130 may be connected to the first connector 132-1, the second connector 132-2, the third connector 132-4, and the fourth connector 132-4. Based on a user operating the switching unit 130, the switching unit 130 may be configured to connect the first connector 132-1 associated with the power source 112 to one or more other connectors 132. In addition, the switching unit 130 does not necessarily have to be connected to the fourth connector 132-4 associated with the external device 128 or include the fourth connector 132-4. Rather, the first connector 132-1 may be connected to the connector interface unit 133 without using the fourth connector 132-4 and/or the switching unit 130. In this example, a constant flow of electrical power may be provided to the connector interface unit 133.
The switching unit 130 may include any type of switching mechanism that provides a connection(s) between the first connector 132-1 associated with the power source 112 and one or more other connectors 132. Also, the switching unit 130 may provide an open circuit, e.g., no connections between the first connector 132-1 and the other connectors 132. In some examples, the switching unit 130 may be a rocker switch, a rotary switch, slide switch, and/or push button switch having 2 or more positions. In one example, the switching unit 130 may be partly exposed outside the housing 131 in order to permit a user to operate the switching unit 130. As such, if a user operates the switch from an open position to a first position, the switching unit 130 may provide a connection between the first connector 132-1 and the second connector 132-1 associated with the first component 122-1, thereby re-routing electrical power back to the first vehicle 102 in order to illuminate the external lighting 110, for example. If a user operates the switch from the first position to a second position, the switching unit 130 may provide a connection between the first connector 132-1 and the third connector 132-3 associated with the second component 122-2, thereby re-routing electrical power back to the first vehicle 102 in order to illuminate the tail and license lights 106, for example. In addition, the switching unit 130 may be moved to a third position that activates two or more components 122 associated with the first vehicle 102. However, the embodiments encompass any type of arrangement of these components to provide the desired access to the power source 112.
In some examples, the connector device 126 may include an overload circuit 111 configured to protect the electrical components of the connector device 126 from damage caused by overcurrent, overload, and/or short-circuit. The overload circuit 111 may detect a fault (e.g., overload, overcurrent, and/or short-circuit) and interrupt the current flow through the connector device 126. The overload circuit 111 may be manually or automatically reset to resume normal operations. In some examples, the overload circuit 111 is a circuit breaker. In other examples, the overload circuit 111 is a fuse.
FIGS. 3A-3E illustrate various views of a connector device 300 according to another embodiment. In some examples, the connector device 300 includes all of the features and functionalities described above with respect to the connector device 126 of FIG. 1A and 2. FIG. 3A illustrates a perspective of the connector device 300 according to an embodiment. Similar to the connector device 126 of FIG. 1B, the connector device 300 may be configured to be coupled to the cord-end connector 116 of the connection cord 120 of the first vehicle 102, and the connector device 300 may be configured to provide access to the power source 112 included on the first vehicle 102. As indicated above, the connection cord 120 may be designed to be connected to the second vehicle 114 for purposes of towing the first vehicle 102.
However, instead of connecting the connection cord 120 to the second vehicle 114, the connector device 300 may be coupled to the cord-end connector 116 of the connection cord 120. The connector device 300 is configured to allow access to the power source 112 that is otherwise not accessible. In one example, the connector device 300 is configured to receive electrical power from the power source 112 and re-route the electrical power back to the first vehicle 102 in order to activate the external lighting 110. As indicated above, the connector device 300 may receive the electrical power via one or more internal wires 119 of the connection cord 120, and route the electrical power back to the first vehicle 102 via another internal wire 119 in order to activate the external lighting 110.
Referring to FIG. 3A, the connector device 300 may include an outer casing 301 having a base portion 306, an extension portion 308, and a lid 310 connected to a portion of the extension portion 308. The base portion 306 may enclose the internal components (e.g., internal components 330 of FIG. 3D) of the connector device 300. In one example, the base portion 306 may be generally circular or tubular in shape. Also, the base portion 306 may define a lumen (e.g., inside space of a tubular structure) extending through the length of the base portion 306, where the lumen is configured to receive the internal components of the connector device 300.
The extension portion 308 may be integrally formed with the base portion 306. The extension portion 308 may be disposed on the end of the base portion 306 that receives the cord-end connector 116 of the connection cord 120. The extension portion 308 may extend outwardly from the tubular structure of the base portion 306 in a manner that the extension portion 308 appears to be substantially square. The other end of the base portion 306 (e.g., opposite of the extension portion 308) includes an opening 304. In this context, the size of the lumen of the base portion 306 may decrease at various portions along the length of the base portion 306 starting from the extension portion 308 to the opening 304. In one example, the size of the lumen of the base portion 306 may be smallest at the location where the opening 304 is formed.
The opening 304 in the base portion 306 may be size to receive a rocker switch 302. As further explained later in the disclosure, the rocker switch 302 may be configured to provide a connection that permits the electrical power to be re-routed back to the first vehicle 102 thereby activating the external lights 110. As shown in FIG. 3A, the rocker switch 302 is partly exposed outside the base portion 306 such that a user can move the rocker switch 302 from a first position to a second position, and vice versa. In one example, when the rocker switch 302 is in the first position, the rocker switch 302 provides the connection between two connectors (e.g., one is associated with the power source 112 and the other one is associated with the external lighting 110) that permits the electrical power to be re-routed back to the first vehicle 102 to activate the external lighting 110. When the rocker switch 302 is in the second position, the rocker switch 302 does not provide a connection between these connectors (e.g., creating an open circuit), thereby de-activating the external lighting 110.
FIG. 3B illustrates a front view of the connector device 300 according to an embodiment. As shown in FIG. 3B, the lid 310 may open and close in order to permit the cord-end connector 116 of the connection cord 120 to be inserted into the connector device 300. The lid 310 may be connected to the extension portion 308 via a spring hinge 312 that is biased to the closed position. The connector device 300 may define an opening 314 to the lumen that extends to the opening 304 shown in FIG. 3A. As shown in FIG. 3B, a plurality of connectors 316 be disposed within the lumen of the base portion 306. For example, the plurality of connectors 316 may be disposed in a location within the lumen that is recessed from the opening 314. The connectors 316 may be similar to the connectors 132 described with reference to FIG. 2.
Also, the base portion 306 of the connector device 300 may define a recess 311 proximate to the opening 314. The recess 311 may permit the proper orientation when the cord-end connector 116 of the connection cord 120 is coupled to the connector device 300. For example, the recess 311 has a structure that relates to a structure on the cord-end connector 116 that allows the cord-end connector 116 to be inserted into the opening 314 in only one orientation in order to ensure that the connectors 316 connect with the corresponding connectors of the cord-end connector 116.
FIG. 3C illustrates a side view of the connector device 300 according to an embodiment. For example, as described above, the connector device 300 includes the base portion 306 having a generally tubular shape. One end of the base portion 306 includes the extension portion 308 that is connected to the movable lid 310, and the other end of the base portion 306 includes the rocker switch 302 that is partly exposed outside the base portion 306.
FIG. 3D illustrates internal components 330 of the connector device 300 according to an embodiment. The internal components 330 may include a connector unit 320 and a plurality of terminal extenders 326. The connector unit 320 may include a connector housing 322, and the plurality of connectors 316. The connector housing 322 may be adapted to secure the plurality of connectors 316 in an arrangement such as a circular arrangement. Each connector 316 may have a first portion 316-1 that extends on one side of the connector housing 322 and a second portion 316-2 that extends on the other side of the connector housing 322. The first portion 316-1 of each connector 316 may be configured to be connected to a corresponding connector on the cord-end connector 116. The second portion 316-2 of one or more connectors 316 may be connected to the terminal extender 326. In one example, a fastener 324 (e.g., screw) may be inserted into the second portion 316-2 to secure the terminal extender 326 to the second portion 316-2.
In one example, the terminal extenders 326 may include a first terminal extender 326-1 and a second terminal extender 326-2. The first terminal extender 326-1 may be connected to the second portion 316-2 of a connector 316 corresponding to the power source 112. The second terminal extender 326-2 may be connected to the second portion 316-2 of a connector 316 corresponding to the external lighting 110. The first terminal extender 326-1 and the second terminal extender 326-2 may be connected to the rocker switch 302 shown in FIG. 3A. As such, when the rocker switch 302 is switched to one of the two positions, the rocker switch 302 may complete the connection from the connector 316 corresponding to the power source 112 and the connector 316 corresponding to the external lighting 110 via the first terminal extender 326-1 and the second terminal extender 326-2 via the second terminal extender 326-2. Therefore, the connector device 300 may re-route the electrical power back to the first vehicle 102 to illuminate the external lighting 110.
FIG. 3E illustrates the unassembled connector device 300 having the internal components 330, the outer casing 301, and the rocker switch 302 according to an embodiment. For example, the internal components 330 may be inserted into the opening 314 of the base portion 306 such that the internal components 330 fit within the lumen of the base portion 306. The rocker switch 302 may be inserted into the opening 304 of the base portion 306. The first terminal extender 326-1 may be connected to a first prong 303-1 of the rocker switch 302, and the second terminal extender 326-2 may be connected to a second prong 303-2 of the rocker switch 302. The internal components 330 may be secured within the lumen of the base portion 306 based on an interference fit or secured with any type of fastener(s). Also, the rocker switch 302 may be secured within the lumen of the base portion 306 based on an interference fit or secured with any type of fastener(s).
FIG. 3F illustrates an example of a cord-end connector 360 of the connection cord 120 according to an embodiment. In some examples, the cord-end connector 360 is the cord-end connector 116 as previously described. The cord-end connector 360 may include a plurality of connectors 362 that are arranged in a circular fashion and in the same arrangement as the connectors 316 of the connector device 300. In this example, the connectors 362 may be female connectors designed to receive the connectors 316 of the connector device 300. Further, the cord-end connector 360 may include a protrusion 364 having a size that can fit within the recess 311 of the connector device 300. The fitting of the protrusion 364 of the cord-end connector 360 within the recess 311 of the connector device 300 allows the connectors 362 to align with the corresponding connectors 316 of the connector device 300.
FIG. 4 illustrates example operations of the connector device 126/300 according to an embodiment. Although FIG. 4 is illustrated as a sequential, ordered listing of operations, it will be appreciated that some or all of the operations may occur in a different order, or in parallel, or iteratively, or may overlap in time.
Power from a connection cord of a first vehicle designed to be coupled to a second vehicle capable of towing the first vehicle may be received (402). For example, the connector device 126/300 may be coupled to the cord-end connector 116/360 of the connection cord 120. The connection cord 120 may be designed to be coupled to the vehicle-end connector 118 of the second vehicle 114 for purposes of towing the first vehicle 102. However, instead of coupling the cord-end connector 116/360 of the connection cord 120 to the vehicle-end connector 118 of the second vehicle 114, the connector device 126 may be coupled to the cord-end connector 116/360 of the connection cord 120.
The connection cord 120 may extend from the first vehicle 102, and the cord-end connector 116/360 may be located on the end of the connection cord 120. The cord-end connector 116/360 may include connectors (e.g. connectors 117/362) that are directly or indirectly connected to one or more internal wires 119 that extend along at least the length of the connection cord 120. One or more of these internal wires 119 may be associated with the power source 112. As such, the internal wire 119 associated with the power source 112 may extend further into the first vehicle 102 and may be connected to the power source 112. Alternatively, the internal wire 119 associated with the power source 112 may be connected to one or more intermediate components (e.g., an electrical panel, or other type of electrical relay) which then provides a connection to the power source 112. As such, the connection cord 120 includes at least one internal wire 119 that directly or indirectly provides a connection to the power source 112.
Typically, this power source connection is used for charging the power source 112 by the second vehicle 114 when the connection cord 120 is coupled to the second vehicle 114. For example, this power source connection is not originally designed to supply electrical power, but rather to receive it from the second vehicle 114 for purposes of charging the power source 112. As such, the power source 112 is originally designed to be a power source within the actual first vehicle 102—not supplying electrical power via the connection cord 120.
As discussed above, the connector device 126 may include an arrangement of connectors 132/316 and the housing 131 (outer casing 301). The housing 131/outer casing 301 may have a shape that is designed to correspond to a housing associated with the cord-end connector 116 to ensure that one or more connectors 132/316 of the connector device 126/300 properly align with the connectors 117/362 of the cord-end connector 116/360. In one example, the housing 131/outer casing 301 may be designed to be coupled with the housing of the cord-end connector 116 such that the fit between these two housing may occur when the housing 131/outer casing 301 is orientated in a specific way with respect to the housing of the cord-end connector 116.
Access to a power source included within the first vehicle may be provided (404). For example, the connector device 126/300 may be configured to provide access to the power source 112 included within the first vehicle 102. The connector device 126/300 may be coupled to the cord-end connector 116/360 of the connection cord 120 in a manner that connects the internal wire 119 corresponding to the power source 112 to another internal wire 119, or more generally, provides access to the internal wire 119 corresponding to the power source 112. Because this connection to the power source 112 is active (e.g., the internal wire 119 is an active line at all times or most times), when coupled, the connector device 126/300 may actually receive electrical power from the power source 112 via the connection cord 120.
In some embodiments, electrical power may be re-routed back to the first vehicle (404-1). For instance, the provided access may include re-routing the electrical power back to the first vehicle 102. For example, the connector device 126/300 may be configured to re-route the electrical power back to the first vehicle 102.
In particular, the connector device 126/300 may be configured to re-route the electrical power received from the connector associated with the internal wire 119 corresponding to the power source 112 back to the first vehicle 102 along a different internal wire 119 of the connection cord 120 that may be at least indirectly connected to the external lights 110, for example. In this context, the connector device 126/300 may provide one or more bridges (or connection points) between the connector 117/362 of the cord-end connector 116/360 that is associated with the power source 112 and the connector(s) 117/362 of the cord-end connector 116 that is associated with one or more components 122 such as the external lights 110. The bridges or connections points associated with the connector device 126/300 may be connectors (e.g., 132/316) and/or switches (130 or 302). Therefore, the connector device 126/300 may be configured to receive electrical power from the power source 112 via the connection cord 120, and then re-route the electrical power back to the first vehicle 102 for activating the one or more components 122 on the first vehicle 102.
Power may be provided to an external device coupled to the connector device (404-2). For example, the connector device 126 may be configured to provide electrical power to at least one external device 128 that is coupled to the connector device 126.
The external device 128 may include a phone, smartphone, computer, laptop, tablet, or generally any type of computing device requiring electrical power. For example, the connector device 126 may be configured to be directly or indirectly coupled to the external device 128 via a standard power cord associated with the external device 128, for example. The connector device 126 may be configured to power or charge the external device 128 based on the provided access when coupled to the external device 128 and the cord-end connector 116 of the connection cord 120. For example, the connector device 126 may provide one or more bridges (or connection(s)) between the internal wire 119 or connector 117/362 of the cord-end connector 116 that is associated with the power source 112 and the connector interface unit 133, disposed on the connector device 126, that is configured to connected to the external device 128.
The connector interface unit 133 may be any type of electrical component configured to allow the external device 128 to be connected to the connector device 126. For example, the connector interface unit 133 may be adapted to connect to the external device 128 directly or via a power cord. In one example, the connector interface unit 133 may be configured to receive a power cord associated with the external device 128 via a USB or standard two-prong electrical socket.
