     DETAILED DESCRIPTION 
     Representative applications of methods and apparatus according to the present application are described in this section. These examples are being provided solely to add context and aid in the understanding of the described embodiments. It will thus be apparent to one skilled in the art that the described embodiments may be practiced without some or all of these specific details. In other instances, well known process steps have not been described in detail in order to avoid unnecessarily obscuring the described embodiments. Other applications are possible, such that the following examples should not be taken as limiting. 
     In the following detailed description, references are made to the accompanying drawings, which form a part of the description and in which are shown, by way of illustration, specific embodiments in accordance with the described embodiments. Although these embodiments are described in sufficient detail to enable one skilled in the art to practice the described embodiments, it is understood that these examples are not limiting; such that other embodiments may be used, and changes may be made without departing from the spirit and scope of the described embodiments. 
     Electronic devices typically generate heat when performing computations or carrying out actions requested by a user. In demanding circumstances, the electronic device may have to enter a lower power mode in order to avoid an overheating condition. In some embodiments, the lower power mode can involve a lower display brightness and/or a lower operating frequency for a processor of the electronic device. For small form-factor computing devices, a heat dissipation system responsible for dissipating the heat often relies upon spreading the heat over an exterior surface of the electronic device. Unfortunately, placing the electronic device in a protective case can compromise the efficiency of a heat dissipation system configured to operate in this manner. For example, a protective case formed from insulating materials can trap heat that would normally be dissipated by convection. This can result in the electronic device having to shift into a lower power mode earlier to avoid an overheating condition. 
     One solution to this problem is to incorporate a heat-spreading device into the protective case. When the protective case is configured to electrically couple with the electronic device using a protruding connector, the protruding connector on the protective case can be thermally coupled with a connector receptacle of the electronic device. By thermally coupling a portion of the protruding connector with a heat-spreading device, heat from the connector receptacle can be received and spread across the protective case in order to dissipate heat more efficiently. 
     In some embodiments, the electronic device can be designed specifically to dissipate heat to the protruding connector. For example, the electronic device can have an internal thermally conductive pathway for transferring heat from heat emitting components within the electronic device to the connector receptacle. 
     In some embodiments, other accessory types can be utilized that are configured to draw heat out of an electronic device by way of the connector receptacle of the electronic device. Some examples include electronic device docks and game controllers configured to dock with the electronic device. 
     These and other embodiments are discussed below with reference to  FIGS. 1-4 ; however, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes only and should not be construed as limiting. 
       FIG. 1A  shows a perspective view of an electronic device case  100  that includes sidewalls  102  that cooperate to define a recess  104  sized to receive an electronic device. Electronic device case  100  also includes connector plug  106  having a hollow body that protrudes into recess  104 . Connector plug  106  can be configured to enable communication and/or power transfer between the electronic device and electronic device case  100 . Connector plug can take many different forms. For example, connector plug  106  can take the form of a USB® plug, a Lightning® plug or another small form-factor data plug. In some embodiments, the electronic device can be configured to power electronic components within electronic device case  100 . In some embodiments, electronic device case  100  includes protrusion  108 , which can be configured to accommodate electrical components supporting the operation of electronic device case  100 . For example, a battery could be positioned within rear protrusion  108 . The battery can be configured to provide power to the electronic device. Alternatively, memory modules can be positioned within protrusion  108 . Protrusion  108  could also include an auxiliary camera module. The camera module could be configured to transfer any images or video taken to the electronic device using the electronic connection established by connector plug  106 . 
       FIG. 1A  also shows an external power receptacle  110 . External power receptacle  110  can be configured to power electronic device case  100  and/or an electronic device disposed within electronic device case  100 . Electronic device case  100  can also include audio ports  112  configured to allow audio waves to exit and leave from one end of the electronic device. In some embodiments, electronic device case  100  includes thermally conductive strips  114  embedded within sidewalls  102 . When the electronic device is positioned within recess  104 , thermally conductive strips  114  can be configured to press against an exterior surface of the electronic device. Thermally conductive strips  114  can be thermally coupled to a heat-spreading component disposed within sidewalls  102  so that the heat received can be spread evenly across sidewalls  102  and/or transferred to a rear surface of electronic device case  100 . 
       FIG. 1B  shows a perspective view of electronic device case  100  with an electronic device  200  inserted therein. Electronic device  200  can include a display  202  for presenting content to a user. Electronic device  200  can also include a speaker situated proximate one or both of audio ports  112 . Electronic device case  100  can be formed from polymeric materials. In some embodiments, polymeric portions of electronic device case  100  proximate regions of electronic device  200  known to be more prone to heating are doped with thermally conductive material to increase the thermally conductivity of those portions of electronic device case  100 . 
       FIG. 2  shows a cross-sectional view of electronic device case  100  with electronic device  200  inserted therein. Electronic device  200  includes a number of heat emitting components. Two of the components likely to emit large amounts of heat are processor  204  and camera module  206 . Electronic device  200  can include thermally conductive pathway  208 , which can spread heat from processor  204  and camera module  206  to connector receptacle  210 . In some embodiments, thermally conductive pathway  208  can take the form of a sheet of thermally conductive material shaped to avoid obstructions within electronic device  200 . In some embodiments, the sheet of thermally conductive material can take the form of a pyrolytic graphite sheet, which has excellent in-plane heat transfer properties. 
       FIG. 2  also features close up view  212  of one end of electronic device case  100 . Close up view  212  shows connector plug  106  engaged within connector receptacle  210 . Connector plug  106  includes a thermally conductive core  116 . Thermally conductive core  116  can take the form of a data connector assembly that is configured to transfer power and/or data signals to electrical component  122  as well as draw the heat received by connector plug  106  along a thermally conductive pathway  118  of the data connector assembly to a thermally conductive plate  120 . Thermally conductive pathway  118  can be a thermally conductive substrate configured to channel heat to a heat spreader such as thermally conductive plate  120 . Thermally conductive plate  120  can take the form of a copper plate or stack of graphite sheets in some embodiments. Thermally conductive plate  120  can help improve the efficiency of electronic device case  100  and electronic device  200  by radiating heat away from electronic device case  100 . In some embodiments, thermally conductive plate  120  can help dissipate heat from an electrical component  122  positioned adjacent to thermally conductive plate  120 . 
       FIG. 2  also shows a secondary thermally conductive pathway  124 , which can be configured to couple with a lateral surface of camera module  206 . This can be particularly effective when a windowed opening  207  for camera module  206  is in direct contact with the lateral surface of camera module  206 . In some embodiments, the second thermally conductive pathway  124  can extend all the way around windowed opening  207 . This configuration could also help distribute heat received from electronic device  200  more evenly across thermally conductive plate  120 , since heat received at connector plug  106  is received at the opposite side of thermally conductive plate  120 . Thermally conductive pathway  124  can take the form of a thermally conductive material, such as copper, embedded within electronic device case  100  and extending between camera module  206  and thermally conductive plate  120  as depicted. 
       FIG. 3A  shows a perspective view of connector plug  106  engaged with components of connector receptacle  210 . Retaining clip  302  of connector receptacle  210  is configured to engage detents  304  defined by opposing surfaces of connector plug  106 . In some embodiments, thermally conductive core  116  can extend near the exterior surface material within detents  304  or in some embodiments extend to the surfaces defining detents  304  in order to improve the thermal coupling between retaining clip  302  and connector plug  106 . Thermally conductive pathway  208  can be coupled directly to retaining clip  302  so that heat from within electronic device  200  can be efficiently coupled to thermally conductive core  116  of connector plug  106 . An electrical component of connector receptacle  210  can be configured to contact and transmit signals to surface contacts  306  of connector plug  106  using spring pins  308 . In generally, heat is transferred through retaining clip  302  while electrical component  304  functions primarily to exchange data and/or power with connector plug  106 . Spring pins  308  can be held in position by connector body  309 , a portion of which has been removed to more clearly depict a size and shape of spring pins  308 . 
     In some embodiments, connector receptacle can include an additional component configured to contact region  310  of connector plug  106 . In some embodiments, region  310  of connector plug  106  can rise to contact a portion of connector receptacle  210 . In some embodiments, an arm of connector receptacle  210  can be lowered to engage region  310  of connector plug  106 . This contact can enhance the thermal coupling between connector receptacle  210  and connector plug  106 . It should be noted that additional points of contact between connector receptacle  210  and connector plug  106  can be established to further improve the thermal coupling between connector plug  106  and connector receptacle  210 . 
       FIG. 3B  shows a cross-sectional side view of connector plug  106  engaged within a connector receptacle  210  of electronic device  200  in accordance with section line B-B.  FIG. 3B  also depicts an embodiment of thermally conductive core  116  in detail. A rigid PCB  312  of thermally conductive core  116  is disposed within an interior volume defined by receptacle  210 , as depicted, and formed around a first end of flexible circuit portion  313 , which extends toward other components within electronic device case  100 . In some embodiments, the material making up rigid PCB  312  can be molded around flexible circuit portion  313 . Rigid PCB  312  can be formed from a glass resin such as FR4, while flexible circuit portion  313  can include electrically and thermally conductive pathways arranged within one or more polyimide layers. Grounding springs  314  thermally couple rigid PCB  312  to grounding ring  316  of connector plug  106 . In this way, heat from receptacle  210  can be propagated through grounding ring  316  and grounding springs  314  prior to propagating along thermally conductive core  116 . In some embodiments, receptacle  210  can be elongated and grounding springs  314  made more robust to provide a more thermally conductive pathway for heat to cross an interface between receptacle  210  and connector plug  106 . For example, receptacle  210  can be elongated so as to extend across a larger area of connector plug  106 . Heat generated by electronic device  200  can also be transferred to thermally conductive core  116  through spring pins  308 , surface contacts  306  and internal contacts  318 . Spring pins  308  are also responsible for transferring information and/or power between electronic device  200  and electronic device case  100 . 
       FIG. 3C  shows a second end of flexible circuit portion  313  being coupled to thermal pad  320  and to electrical component  122 . Thermal pad  320  puts flexible circuit portion  313  in direct thermally conductive contact with thermally conductive plate  120  by conducting heat directly from flexible circuit portion  313  to thermally conductive plate  120 . As discussed above, thermally conductive plate is then able to spread and dissipate the heat received from flexible circuit portion  313 . Flexible circuit  313  also carries power and/or data to electrical component  122 . In some embodiments, heat from electrical component  122  is able to flow through flexible circuit portion  313  and through thermal pad  320  into thermally conductive plate  120 . In embodiments where electrical component  122  generates substantial amounts of heat, electrical component  122  can have one or more discrete thermally conduct pathways  322  moving directly from electrical component  122  to thermally conductive plate  120 , as depicted. In some embodiments, electrical component  122  could be in direct contact with thermally conductive plate  120 . 
       FIG. 3D  shows a top view of electrical component  122 , thermally conductive plate  120  and thermally conductive pathways configured to transfer heat to thermally conductive plate  120 . In particular, flexible circuit portion  313  is shown broadening as it approaches thermal pad  320 . By broadening flexible circuit portion  313  the resistance to heat transfer to thermal pad  320  can be substantially reduced, thereby increasing the amount of heat that can be transferred to thermally conductive plate through thermal pad  320 . As depicted, thermal pad  320  can extend entirely across a width of thermally conductive plate  120 . The width of flexible circuit portion  313  can then taper as it approaches electrical component  122  to discourage the flow of heat directly into electrical component  122 . In some embodiments, flexible circuit portion  313  can include one or more thermally conductive layers that include pyrolytic graphite sheets to improve the thermal conductivity of flexible circuit  313 . The thermally conductive layers can terminate at thermal pad  320  to discourage heat from electrical plug bypassing thermal pad  320  and continuing to electrical component  122 .  FIG. 3D  also shows thermally conductive pathway  124  terminating at thermally conductive plate  120 . Thermally conductive pathway  124  can be configured to deliver heat generated by camera module  206  to thermally conductive plate  120 . 
       FIG. 4  shows a back view of electronic device case  100 . In some embodiments, electronic device case  100  can have different heat dissipation zones. For example, heat dissipation zone  402  can take the form of a heat spreader or thermally conductive plate configured to receive heat from an electronic device disposed within electronic device case  100 . As depicted heat dissipation zone  402  surrounds protrusion  108  and can spread heat evenly across the rear surface of electronic device case  100 . Heat dissipation zone  402  can also be configured to spread heat to heat dissipation zone  404  using thermally conductive pathway  406 , which can also include a heat spreader or thermally conductive plate formed from thermally conductive material such as copper or pyrolytic graphite sheets. While only a single thermally conductive pathway is shown joining the heat dissipation zones it should be appreciated that any number of thermally conductive pathways can extend between the heat dissipation zones. In some embodiments, one or more of the thermally conductive pathways can be closed by an electromechanical relay  408 . The electromechanical relay can be configured to shift a portion of thermally conductive pathway  406  to create an air gap, or slide thermally insulating material into the portion of thermally conductive pathway  406 . In this way, heat transfer between the heat dissipation zones can be substantially curtailed. A processor of electronic device case  100  can be configured to adjust the flow of heat between heat dissipation zones  402  and  404  for any number of reasons. For example, when protrusion  108  contains a battery cell, heat transfer between the heat dissipation zones can be severed when it is undesirable to transfer heat from the electronic device to the battery positioned within protrusion  108 . This could be the case where the battery within protrusion  108  is operating above safe operating temperatures.
