Description
- The present invention generally relates to electronic accessories for vehicles and, more particularly, to devices for adding aftermarket electrical accessories to vehicles.
- Adding electrically operated devices to a vehicle is a well-established custom for users of many vehicle types. Electrically operated devices such as spotlights, light bars, interior lights, and the like, in addition to electromechanical devices such as pumps, horns, winches, and the like, can add functionality and convenience to a vehicle. Unfortunately, installing aftermarket devices using a vehicle's electrical system often requires specialized skills. Many individuals desiring these devices have no idea how to install them properly. These devices are often wired directly to a vehicle's electrical system through the vehicle's fuse box. Other methods can be even more confusing and difficult for less technical individuals. Therefore, installing these devices requires one learn how to add discrete components to the existing electrical system available in the vehicle. Various lighting and other additions can also each take a separate circuit in the vehicle's fuse box, limiting the number of additions. To some, this may be a relatively simple process to learn. It is not easy for others and will likely be avoided by not adding additional devices or using professional technicians for the installation, increasing the cost substantially. Either way, there is a learning curve to overcome through study or previous knowledge. Furthermore, errors in installing devices can damage the vehicle or the devices. Accordingly, continued improvement in the art is evident.
- Briefly, to achieve the desired objects and advantages of the instant invention, provided is a modular power distribution system. The modular power distribution system includes a power distribution block with a switch socket having a first format and a device socket having a second format different from the first format. The switch socket and the device socket form a designated socket pair. A relay electrically couples the switch socket to the device socket. The relay, when powered, closes a circuit between the switch socket and the device socket. Input power terminals electrically coupled to the socket pair and the relay are configured to be electrically coupled to an electric power source. A switch wire harness includes wiring having a plug end and a switch end. A switch plug is electrically coupled to the plug end. The switch plug has a first complemental format configured to be removably received by the first format of the switch socket. A device wire harness includes wiring having a plug end and a device end and a device plug electrically coupled to the plug end. The device plug has a second complemental format configured to be removably received by the second format of the device socket.
- The power distribution block can further include a second switch socket having the first format and a second device socket having the second format. The second switch socket and the second device socket form a second designated socket pair distinguishable from the designated socket pair. A second relay electrically couples the second switch socket to the second device socket. The input power terminals are electrically coupled to the second designated socket pair and the second relay.
- The designated socket pair is distinguished from the second designated socket pair by positioning the switch socket and the device socket of the designated socket pair in opposition to one another and positioning the second switch socket and the second device socket of the second designated socket pair in opposition to one another.
- The modular power distribution system can include a signal receiver coupled to the switch socket and the switch wire harness replaced with a control unit. The control unit includes a signal generator which is selectively operable. The signal generator selectively generates a signal associated with the signal receiver to close a circuit between the switch socket and the device socket.
- Also provided is a method of installing electrically operated devices on a vehicle. The method includes providing a vehicle with an electric power source. Providing a power distribution block including a switch socket having a first format and a device socket having a second format different from the first format. The switch socket and the device socket form a designated socket pair. A relay electrically couples the switch socket to the device socket. Input power terminals are electrically coupled to the socket pair and the relay. Additional steps include mounting the power distribution block to the vehicle and connecting the electric power source to the input power terminals of the power distribution block. The relay is automatically closed upon being powered by the electric power source, closing a circuit between the switch socket and the device socket. A further step includes providing a switch wire harness including wiring having a plug end and a switch end, a switch plug electrically coupled to the plug end, the switch plug having a first complemental format configured to be removably received by the first format of the switch socket. Inserting the switch plug into the switch socket. A method according to the invention further includes providing a device harness including wiring having a plug end and a device end, a device plug electrically coupled to the plug end, and the device plug having a second complemental format configured to be removably received by the second format of the device socket. Further steps then include inserting the device plug into the device socket, coupling a switch to the switch end, coupling a device to the device end, and operating the device using the switch.

FIGS. 1-3 illustrate a vehicle generally designated 10. Referring in relevant part toFIGS. 1-3 ,vehicle 10 in this specific embodiment is an off-road vehicle having abody 12 defining avehicle cockpit 14 rearward of an engine compartment 15 housing an engine and other standard components. Adashboard 16 with acenter console 18 separates engine compartment 15 fromvehicle cockpit 14. A modular power distribution system, generally designated 20 inFIG. 1 , is installed invehicle 10. Whilevehicle 10 is an off-road vehicle in this embodiment, the person having ordinary skill in the art will readily appreciate that modularpower distribution system 20 is useful with other ground transportation vehicles such as cars, trucks, busses and the like. Furthermore, the term “vehicle” as used herein, is not limited to ground transportation vehicles. Modularpower distribution system 20 is useful for installing electrical accessories to the electrical power source of other vehicles, including boats, aircraft, or any other vehicle having an electrical power source. - With additional reference to
FIG. 4 , illustrated is a preferred embodiment of modularpower distribution system 20. Modularpower distribution system 20 includes apower distribution block 22 coupled between a power system ofvehicle 10, described below, and at least onedevice 23.Device 23 is chosen from various electronically operated accessories such as pumps, horns, lights, etc. While modularpower distribution system 20 can include asingle device 23, it incorporates sixdevices 23 inFIGS. 1, 2 , and 4, although it can incorporate less ormore devices 23. In this example,device 23A is a bar light mounted on top ofbody 12 abovevehicle cockpit 14,device 23B is an electric winch mounted on the front ofbody 12 forward of engine compartment 15, and device 23C is a bar light 23C mounted on the front ofbody 12 above theelectric winch 23B.Device 23D is a spotlight mounted on one side ofbody 12 proximate to the front ofvehicle cockpit 14,device 23E is a spotlight on the opposing side ofbody 12, anddevice 23F is aninterior light 23F mounted withinvehicle cockpit 14 inFIG. 2 .Devices 23 are presented by way of example to show the diversity of the different devices capable of being used with modularpower distribution system 20. Eachdevice 23 is coupled to the power system of the vehicle throughpower distribution block 22. - In
FIG. 4 ,system 20 includes device wire harnesses 24coupling devices 23 topower distribution block 22 and switch wire harnesses 25 coupling switches 27 topower distribution block 22. InFIGS. 2 and 3 , switches 27 are mounted oncenter console 18 ofdashboard 16 for convenient access, and other accessible locations are useful in alternative embodiments. Modularpower distribution system 20 is an exemplary plug-and-play system including modular or self-contained components, namely switch wire harnesses 25, switches 27, device wire harnesses 24, anddevices 23, configured to be easily connected without confusion, the use of specialized tools, or the need for specialized skill. Device wire harnesses 24 and switch wire harnesses 25 have different formats for coupling topower distribution module 22. The different formats between device wire harnesses 24 and switch wire harnesses 25 prevent the unknowing interchanging of these parts. - In
FIGS. 5-7 ,power distribution block 22 is entirely self-contained. It includes a base 30 with afront side 32, aback side 35, and aperipheral edge 37 with threadedapertures 38 formed through the corners thereof, extending from thefront side 32 to theback side 35. With additional reference toFIG. 4 ,power distribution block 22 further includesswitch sockets 40,device sockets 42, relays 44, fuses 46, andterminals 48. InFIGS. 5-7 ,switch sockets 40 extend fromfront side 32 ofbase 30 in an array or bank ofswitch sockets 40, anddevice sockets 42 extend fromfront side 32 ofbase 30 in an array or bank ofdevice sockets 42. Relays 44 extend fromfront side 32 ofbase 30 in an array or bank ofrelays 44, and fuses 46 extend fromfront side 32 ofbase 30 in an array or bank offuses 46. Eachswitch socket 40 from the array ofswitch sockets 40 associates with adifferent device socket 42 of the array ofdevice sockets 42. In this manner, oneswitch socket 40 and onedevice socket 42 form a socket pair electrically coupled by an associatedrelay 44 from the array of relays 44. Thus, eachrelay 44 of the array ofrelays 44 associates with one socket pair. In addition, each fuse 46 of the array offuses 46 associates with one socket pair. Theswitch socket 40 anddevice socket 42 of each socket pair directly oppose one another clearly and un-mistakenly designating each pair ofsockets switch sockets 40 anddevice sockets 42 are each formed in their respective array, each array is linear, and the arrays are parallel to one another. In this embodiment, relays 44 are each between their associated socket pair. However, the positioning ofrelays 44 is not critical because the user does not interact withrelays 44 during installation. Accordingly, relays 44 can be positioned in any convenient location. The described relationship of each socket pair visually and positionally designates the socket pairs from one another to the ordinary observer. - In
FIGS. 4, 5, and 6 ,switch sockets 40 anddevice sockets 42 have different formats. For example, eachswitch socket 40 is a triangular shape with a three-prong connector. Eachdevice socket 42 is a rectangular shape with a two-prong connector. The formats ofswitch sockets 40 are identical, the formats ofdevice sockets 42 are identical, and the formats ofswitch sockets 40 are different from the formats ofdevice sockets 42. The different formats of theswitch sockets 40 from thedevice sockets 42 disable unintentional connection of the wrong components and enable the fitting of only the correct components. Other different formats are useful.Power input terminals 48 are configured to be coupled to a vehicle's electrical power source for poweringpower distribution block 22 and each switch and device component coupled topower distribution block 22. - In
FIGS. 8 and 10 ,power distribution block 22 is fixed to a mountingplate 50. Referring also toFIGS. 11 and 12 , mountingplate 50 includes asupport portion 52 and ahanger portion 54 that extends at an angle fromsupport portion 52.Support portion 52 has atop surface 56 configured to receive thereon backside 35 ofpower distribution block 22. Threadedapertures 58 extending throughsupport portion 52 of mountingplate 50 proximate to the corners thereof align with threadedapertures 38 extending throughpower distribution block 22 whenpower distribution block 22 is properly positioned ontop surface 56.Fastener openings 60 throughhanger portion 54 accommodate fasteners to secure mountingplate 50 tovehicle 10 releasably.FIG. 9 is an enlarged sectional view of an attachment point betweenpower distribution block 22 and mountingplate 50. Ascrew 59 threaded concurrently through threadedaperture 38 ofpower distribution block 22 and threadedaperture 58 ofsupport portion 52 securespower distribution block 22 to mountingplate 50.Screw 59 is countersunk to provide a flush interface withperipheral edge 37. - With additional reference to
FIG. 13 , mountingplate 50 serves to attachedpower distribution block 22 tovehicle 10. Mountingplate 50 can attachpower distribution block 22 to any convenient location. In this embodiment, mountingplate 50 securespower distribution block 22 within engine compartment 15 to a firewall or other structure, in this case a frame member 62 receivinghanger portion 54 there against. Fasteners, such as nuts and bolts, clips, ties, and the like, extend throughfastener openings 60 and engage frame member 62, fixedly attaching mounting plate tovehicle 10.Power cables 65 extend from anelectrical power source 66 ofvehicle 10 and attach conventionally topower input terminals 48. Typically,cables 65 are a power, ground, and ignition lines. - Switch wire harnesses 25 are configured to couple
switches 27 topower distribution block 22 inFIG. 4 . As shown inFIGS. 14 and 15 , eachswitch wire harness 25 includeswires 70 having plug ends 72 coupled to aswitch plug 73 and opposing switch ends 75 coupled to aswitch connector 76.Switch plug 73 has a complemental format matching the format ofswitch socket 40 ofpower distribution block 22.Switch plug 73 is fixedly fastened to ends 72 in this embodiment.Switch connector 76 receivescomplemental connector 78 fromswitch 27, electrically couplingswitch 27 to switchharness 25. In this embodiment,switch connector 76 includes five prong receiving members, andcomplemental connector 78 includes five prongs received by the five prong receiving members. This provides a secure physical and electrical connection betweenswitch 27 andswitch wire harness 25. Other formats are useful forswitch connector 76 andcomplemental connector 78 in alternate embodiments according to the skill attributed to the skilled artisan. In this manner,various switches 27, havingcomplemental connectors 78 with the same format asswitch connector 76, can be used, easily replacingswitches 27 if desired.FIG. 16 illustratescomplemental connector 78 ofswitch 27 prepared to be inserted intoswitch connector 76 shown as it would appear configured with a protective shroud.FIG. 17 corresponds toFIG. 16 and illustratescomplemental connector 78 ofswitch 27 inserted intoswitch connector 76, electrically couplingswitch 27 to switchharness 25 with theswitch 27 in an off position (opened switch) for deactivating its corresponding device.FIG. 18 illustratesswitch connector 76electrically coupling switch 27 to switchharness 25 with theswitch 27 toggled to an on position (closed switch) for activating its corresponding device. Ends 75 can be hardwired to switchconnector 76 allowing for quick and easy replacement ofswitch 27 inFIG. 18 , or include ends 75 inFIG. 20 free to be wired to switch 27 as desired and shown inFIG. 20 . Switch wire harnesses 25 havinghardwired switch connector 76 requireswitches 27 have the same complemental connector format, while switch wire harnesses 25 having ends 75 free allow more flexibility with the selection of switches 27. - Device wire harnesses 24 are configured to couple
devices 23 topower distribution block 22 inFIG. 4 . When switch wire harnesses 25 couple switches 27 topower distribution block 22 and device wire harnesses 24couple devices 23 topower distribution block 22 inFIG. 4 , switches 27 are operatively coupled to therespective devices 23, wherein eachdevice 23 is deactivated when itscorresponding switch 27 is off and activated when itscorresponding switch 27 is on. - In
FIG. 19 , eachdevice wire harness 24 includeswires 80 with plug ends 82 coupled to adevice plug 83 and the opposing device ends 85 coupled todevice 23.Device plug 83 has a complemental format that matches the format ofdevice socket 42 ofpower distribution block 22 and specifically does not have the same format asswitch plug 73.Device plug 83 is fastened fixedly to ends 82 in this embodiment. Ends 85 can be hardwired todevice 23 as shown inFIG. 19 , or include ends 85 free to be wired todevices 23 as desired and shown inFIG. 21 . Device wire harnesses 24 havinghardwired devices 23 would be provided with therespective device 23, while device wire harnesses 24 having ends 85 allowdevices 23 to be provided separately and wired when needed, increasing flexibility and types of devices available. - Device wire harnesses 24 and switch wire harnesses 25 each
electrically couple devices 23 and switches 27 topower distribution block 22 as can be seen with reference toFIGS. 4, 22, and 23 .FIG. 22 illustratessystem 20 with switch plug 73 ofswitch wiring harness 25 positioned to be inserted into a selected one ofswitch sockets 40 of the array ofswitch sockets 40 to electrically couple switch 27 topower distribution block 22.Device plug 83 ofdevice wiring harness 24 is positioned to be inserted into one ofdevice sockets 42 of the array ofdevice sockets 42 associated with the selectedswitch socket 40 as a socket pair toelectrically couple device 23 topower distribution block 22 and thereby electrically and operatively couple switch 27 todevice 23 through the socket pair ofpower distribution block 22.FIG. 23 illustratesswitch plug 73 and device plug 83 inserted inswitch socket 40 anddevice socket 42 of a socket pair operatively coupling theswitch 27 to itscorresponding device 23, which activates when itscorresponding switch 27 is on and deactivates when itscorresponding switch 27 is off. As described previously, aspecific device 23 to be controlled by aspecific switch 27 are inserted intodevice socket 42 andswitch socket 40 associated as a socket pair and electrically coupled by one of arelay 44 from the array ofrelays 44 to form a circuit coupled to the vehicle electric power source. In this embodiment, an additional five socket pairs with associatedrelays 44 and fuses 46 are provided. Each socket pair with associatedswitch wire harness 25 and associated device wire harness complete a circuit withinpower distribution block 22. One of ordinary skill in the art will understand thatpower distribution block 22 can incorporate more or less socket pairs as desired. - In
FIG. 4 , aswitch wire harness 25 and adevice wire harness 24 is coupled to eachswitch socket 40 anddevice socket 42 electrically coupling the opposingswitch 27 anddevice 23 of each socket pair. When power is applied to inputterminals 48 from the electrical power source ofvehicle 10, eachrelay 44 of the array ofrelays 44 is automatically energized and closed to complete an electrical connection betweendevice socket 42 andswitch socket 40 of each socket pair. Relays 44 are in separate circuits from the device/switch circuits of each socket pair. Thus, one lead of the switch socket is connected to one lead of the device socket. Also, one lead or contact of each of the fuses is connected to the power and the other lead is connected to the second lead of the device socket. The other lead of the switch socket is connected to a power return (e.g. ground or a negative lead of the power source) to complete each device/switch circuit in a socket pair. Thus, when the device is plugged into the device socket and the switch is plugged into the switch socket of a socket pair, closing or turning the switch to the on position completes a circuit throughpower distribution block 22 for that socket pair and causes the device to operate. Fuses are on the hot side of the line of the socket pair so when a fuse blows the entire circuit is open. -
FIG. 24 illustrates modularpower distribution system 20 with switch wire harnesses 25 and device wire harnesses 24 attached to socket pairs ofpower distribution block 22 withends switches 27 ordevices 23. In this exemplary embodiment, any selected switch or device can be attached tosystem 20. -
FIGS. 25 and 26 illustrate another embodiment of apower distribution block 122 for use as a part of modularpower distribution system 20.Power distribution block 122 is entirely self-contained and includes a base 130 having a front side 132, aback side 135, and aperipheral edge 137 with threadedapertures 138 formed through the corners thereof and extending from the front side 132 toback side 135.Power distribution block 122 includes aswitch socket 140, adevice socket 142, arelay 144, and afuse 146.Switch socket 140,device socket 142,relay 144, and fuse extend from front side 132 ofbase 130.Switch socket 140 associates withdevice socket 142 forming a socket pair. The socket pair includesswitch socket 140 anddevice socket 142 electrically coupled byrelay 144. Fuse 146 operatively associates with the socket pair. In this embodiment ofpower distribution block 122, specific positioning ofswitch socket 140 anddevice socket 142 is not necessary to designate the socket pair since its designation is clear, with only two sockets being present.Relay 144 and fuse 146 are positioned adjacent to the socket pair. Power input terminals 148 are configured to receive electrical power from an electric power source and are in electric communication with the socket pair. -
Power distribution block 122 inFIGS. 25 and 26 is configured to be mounted in a manner similar topower distribution block 22, including using a mounting plate 50 (not shown) fixed topower distribution block 122 with screws threaded concurrently throughapertures 138 into apertures formed in mountingplate 50. Aswitch wire harness 25 and adevice wire harness 24, as previously described, can be coupled to switchsocket 140 anddevice socket 142, respectively, as designated by the format of the sockets to electricallycouple switch 27 anddevice 23 topower distribution block 122. When power is applied to input terminals 148 from the electrical power source,relay 144 automatically energizes and closes to complete an electrical connection betweendevice socket 142 andswitch socket 140 of the socket pair. Whenswitch 27 is closed (moved to the on position), the circuit is closed, providing electric power todevice 23. - As illustrated in
FIG. 27 , in a particular embodiment, modularpower distribution system 20 is enabled with a short-range wireless technology configured to wirelessly couple switches 27 (oneswitch 27 is shown inFIG. 27 for illustrative purposes) to the respective relays 44 enabling eachdevice 23 to activate via its correspondingrelay 44 when the correspondingswitch 27 is on and generates an ON signal and deactivate via its correspondingrelay 44 when the correspondingswitch 27 is off and generates an OFF signal. Any suitable and readily available short-range wireless technology can be used. In this embodiment, eachsocket 40 receives a switch radio receiver unit 150. Switch radio receiver unit 150, when an ON signal is received from its correspondingswitch 27, closes the circuit for thecorresponding device 23 allowing electrical power to reachdevice 23 and “turn it on”. Switch radio receiver unit 150, when an OFF signal is received from its correspondingswitch 27, opens the circuit for thecorresponding device 23 disabling electrical power from reachingdevice 23 and “turn it off”. Switch radio receiver unit 150 will not be described in detail, as they are well known, and used in many applications such as wireless lights, socket adaptors and the like. Switch radio receiver unit 150 may be configured with a transceiver configured to receive signals from its corresponding switch and to send corresponding signals to a wireless receiver of a device for turning it on and off. - With additional reference to
FIGS. 28-30 , a wireless switch assembly, generally designated 170, is illustrated and acts as a control unit for the associated devices. Referring in relevant part toFIGS. 28-30 ,wireless switch assembly 170 includes aswitch enclosure 172 carrying acircuit board 173 havingswitch sockets 174.Switch sockets 174 have a format, such as illustrated with multiple contacts. As discussed previously, any format can be employed.Switches 175, each having aswitch plug 176, are received byswitch enclosure 172 and each is attachable to a separate one ofswitch sockets 174. Switch plugs 176 have a complemental format matching the format ofswitch sockets 174 ofcircuit board 173. As withswitch sockets 174, substantially any format can be employed, provided it is compatible with the format ofswitch sockets 174.Circuit board 173 carries a signal generator such as awireless chip 178 for each ofswitch sockets 174. Thus, each ofswitches 175 is associated with one ofwireless chips 178.Switch sockets 174 receive switch plugs 176 fromswitch 175,electrically coupling switch 175 tocircuit board 173. When activated, each wireless chip sends a signal, such as a radio frequency signal, to an associated one of switch radio receiver unit 150. - A
bracket 180 is attached to switchenclosure 172 byfasteners 182, such as screws and the like. Abattery housing 185, having aplug 189, is attached to switchenclosure 172.Battery housing 185 carriesbatteries 187 which are electrically coupled to plug 189. Areceptacle 190 is carried byswitch enclosure 172 and is electrically coupled tocircuit board 173. Whenbattery housing 185 is fitted to switchenclosure 172, plug 189 is received byreceptacle 190, poweringcircuit board 173. When one ofswitches 175 is moved from an off position to an on position, it activates the associated wireless chip, powered bybatteries 187, to emit a signal. The signal is received by the associated switch radio receiver unit 150 and turns associateddevice 23 on or off as desired. One of ordinary skill in the art will understand that whilewireless switch assembly 170 is used in this embodiment, other options can be used for a control unit such as smart phones and the like that have signal generators which can match a signal receiver. - Referring in relevant part to
FIG. 31 , in another embodiment, modularpower distribution system 20 is again enabled with a short-range wireless technology configured to wirelessly coupleswitches 175 fromwireless switch assembly 170 to the respective relays 44 enabling eachdevice 23 to activate via its correspondingrelay 44 when thecorresponding switch 175 is on and generates an ON signal and deactivate via its correspondingrelay 44 when thecorresponding switch 175 is off and generates an OFF signal. Any suitable and readily available short-range wireless technology can be used. In this embodiment,switch sockets 40 receiving switch radio receiver units 150 have been excluded frompower distribution block 22 and replaced with a wireless receiver chip 200 electrically coupled to relays 44.Transponders 202 mounted onpower distribution block 22 are coupled to wireless receiver chip 200 for signal transmission purposes. Wireless receiver chip 200 functions in a manner similar to switch radio receiver units 150 and can correspond to one or more relays 44. In the preferred embodiment, wireless receiver chip 200 includes multiple signal receivers each corresponding to a different one ofrelays 44 to actuate the associateddevice 23. Each signal receiver of wireless receiver chip 200, when an ON signal is received from acorresponding switch 175 ofwireless switch assembly 170, closes the circuit for thecorresponding device 23 allowing electrical power to reachdevice 23 and “turn it on”. Each signal receiver of wireless receiver chip 200, when an OFF signal is received from acorresponding switch 175 ofwireless switch assembly 170, opens the circuit for thecorresponding device 23 disabling electrical power from reachingdevice 23 and “turn it off”. - Protection of unused sockets of modular
power distribution system 20 is desirable in many circumstances. Referring toFIG. 32 ,power distribution block 22 is illustrated withswitch socket blanks 220 anddevice socket blanks 222 inserted inunused switch sockets 40 anddevice sockets 42, respectively.FIG. 31 illustratespower distribution block 22 withdevice socket blanks 222 inserted inunused device sockets 42. With additional reference toFIG. 33 ,switch socket blanks 220 are configured to be received withinswitch sockets 40. To this end,socket blanks 220 have an appropriate triangular shape andreceptacles 224 for receiving the three-prong connector fromswitch sockets 40.Switch socket blanks 220 can be friction fit or latched in position, and are intended to prevent dirt and moisture from entering anun-used switch socket 40 and prevents damage and degradation thereof. One of ordinary skill in the art will understand thatswitch socket 40 can have a different format and thatswitch socket blanks 220 are configured with the appropriate format. - Still referring to
FIG. 32 , with additional reference toFIG. 34 ,device socket blanks 222 are configured to be received withindevice sockets 42. To this end,device socket blanks 222 have an appropriate rectangular shape andreceptacles 226 for receiving the two-prong connector fromdevice sockets 42.Device socket blanks 222 can be friction fit or latched in position, and are intended to prevent dirt and moisture from entering anun-used device socket 42 and prevents damage and degradation thereof. One of ordinary skill in the art will understand thatdevice socket 42 can have a different format and thatdevice socket blanks 222 are configured with the appropriate format. - Still referring to
