Abstract
Connector receptacles that can provide a robust and reliable connection to a board and have a small form factor. An example can provide connector receptacles that provide a robust and reliable connection to a board by providing contacts having highly planarized solder tails. The solder tails can be supported by extensions of housing portions to provide consistent placement and alignment, as well an amount of shock absorption. The solder tails can include chamfered surfaces to improve soldered connections to pads of a board. The chamfered surfaces can also enable a reduced pitch between solder tails thereby helping to provide a reduced form factor.

DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS
[0027]
[0028]
[0029] Electronic device 100 can include a battery (not shown) that can be charged through connector receptacle 200. Electronic device 100 can include other electronics, such as memories, processors, battery controllers, and other circuits (not shown.) These circuits can be located on one or more boards 300 (shown in
[0030] Electronic devices, such as electronic device 100, can on occasion be inadvertently dropped or thrown. Remotes, such as electronic device 100 shown here, can be used as a controller for gaming and for selecting programming on a streaming device. As a result of the dynamic nature of their use, electronic device 100 can be subject to shock that can damage internal components and connections. Accordingly, it can be desirable to provide a connector receptacle 200 that can form a robust and reliable connection to board 300 in electronic device 100. Electronic device 100 can also have a limited size, and it can be desirable to maximize internal volume inside electronic device 100 for the battery. Accordingly, it can be desirable to provide a connector receptacle 200 having a small form factor. An example of such a connector receptacle is shown in the following figure.
[0031]
[0032] Connector receptacle 200 can form a robust and reliable connection to board 300. To facilitate this, connector receptacle 200 can be securely attached to enclosure 130 of electronic device 100. Accordingly, top shield 220 can include flanges 222. Flanges 222 can include openings 223 for accepting fasteners (not shown) to attach flanges 222 to enclosure 130 of electronic device 100. This arrangement can prevent movement of connector receptacle 200 away from enclosure 130 during a drop or other impact event. Housing 210 of connector receptacle 200 can include lip or raised portion 214. Raised portion 214 can align with an opening or other feature (not shown) in enclosure 130, thereby reducing any lateral shift during a drop. Housing 210 can also include raised portion 218. Raised portion 218 can fit between top shield 220 and enclosure 130, and between bottom shield 230 and enclosure 130. This can help to reduce movement of tongue 280, top housing portion 250, and bottom housing portion 270 (both shown in
[0033] Contacting portions 242 of contacts 240 can be located on a top surface of tongue 280, as shown. Contacting portions 262 of contacts 260 (both shown in
[0034]
[0035] Top housing portion 250 can support contacts 240 (shown in
[0036]
[0037] Housing 210 can support tongue 280, top housing portion 250, and bottom housing portion 270. A top side of tongue 280 and top housing portion 250 can support contacts 240, while a bottom side of tongue 280 and bottom housing portion 270 can support contacts 260 (shown in
[0038] Top housing portion 250 can be formed by insert molding and can include extensions 252. Extensions 252 can be formed around and along portions of solder tails 244 of contacts 240. Bottom housing portion 270 can be formed by insert molding and can include extensions 272. Top housing portion 250 can further include slots 253. Slots 253 can provide an amount of compliance to top housing portion 250. This can help to relieve stress that can result when extensions 252 and extensions 272 are fit together during assembly. Extensions 272 can be formed around and along portions of solder tails 264 of contacts 260. Extensions 252 and extensions 272 can be interleaved to form interlocking features. Extensions 252 and extensions 272 are shown in further detail in the following figure.
[0039]
[0040] In the same or similar manner, extensions 272 of bottom housing portion 270 (shown in
[0041] Solder tails 244 and solder tails 264 can include front edges 2491. Front edges 2491 are typically where contacts 240 and contacts 260 (both shown in
[0042] Again, electronic device 100 can be inadvertently dropped or thrown. To prevent damage during such an event, embodiments of the present invention can provide connector receptacles 200 that form a robust and reliable connection to board 300. For example, contacts 240 and contacts 260 of connector receptacle 200 can include bottom surface 241 to be soldered to pads 320 of board 300, where each bottom surface 241 has one or more chamfered or partially chamfered edges, specifically front edge 249 and side edges 247. By way of comparison, traditional flat surfaced solder tails can have regions of stress accumulation when misaligned with pads. These stress regions can break when an electronic device housing the connector receptacle is dropped or inadvertently thrown. The additional area of the chamfered bottom surface 241 can help to reduce or eliminate these stress regions.
[0043] Additionally, contacts 240 and contacts 260 can be supported by top housing portion 250 and bottom housing portion 270. Top housing portion 250 can include extensions 252 and bottom housing portion 270 can include extensions 272 that extend at least partially around and along a portion of solder tails 244 and 264, respectively. Extensions 252 and extensions 272 can be at least partially around and along each solder tail 244 and solder tail 264 (respectively) and can extend to top surface 248 of lateral portion 245 for mechanical support. This mechanical support can help to laterally align, or improve the lateral positions, and help to vertically align, or improve the coplanarity, of solder tails 244 and solder tails 264. Extensions 252 and extensions 272 can be interleaved to form interlocking features. In these ways, extensions 252 and extensions 272 can help to ensure a robust and reliable connection between connector receptacle 200 and pads 320 on board 300.
[0044] Top shield 220 (shown in
[0045] Also, these and other embodiments of the present invention can include features for connector receptacle 200 to have a small form factor. This can be enabled by providing features for connector receptacle 200 that enable a narrow pitch between contact solder tails 244 and solder tails 264. For example, contacts of a connector receptacle can include bottom surface 241 to be soldered to pads 320 of board 300, where bottom surface 241 has a chamfered front edge 249 and side edges 247, which can be all or partially chamfered. The additional area provided by this chamfering to bottom surface 241 can help to ensure a good solder connection between the narrow pitch solder tails 244 and solder tails 264 and pads 320 on board 300 even in the event of a specific amount of misalignment between the two. By way of comparison, traditional flat surfaced contacts would form a poor solder connection in the event of the same specific amount of misalignment. This improved tolerance to misalignment can help to enable the use of the narrow pitch solder tails 244 and solder tails 264, thus enabling connector receptacle 200 to have a small form factor.
[0046] Contacts 240 and contacts 260 of connector receptacle 200 can be supported by top housing portion 250 and bottom housing portion 270, respectively. Top housing portion 250 can include extensions 252 that extend at least partially around and along a portion of solder tails 244. Bottom housing portion 270 can include extensions 272 that extend around and along a portion of solder tails 264. Extensions 252 and extensions 272 can be at least partially around each solder tail 244 and solder tail 264 (respectively) and can extend to top surface 248 of lateral portion 245 of solder tails 244 and solder tails 264 (respectively) for mechanical support. This mechanical support can help to laterally align, or improve the lateral positions, and help to vertically align, or improve the coplanarity, of solder tails 244 and solder tails 264. This improved positioning can help to reduce the variance in lateral and vertical positions of solder tails 244 and solder tails 264, thereby enabling the use of the narrow pitch solder tails 244 and solder tails 264 and enabling connector receptacle 200 to have a small form factor.
[0047] In these and other embodiments of the present invention, each extension 252 and each extension 272 can help to support one or more than one solder tail 244 or solder tail 264, respectively.
[0048]
[0049]
[0050] Top shield 220 can include flanges 222 having openings 223 for accepting a fastener (not shown) to secure connector receptacle 200 to enclosure 130 of electronic device 100. Bottom shield 230 can include side tabs 232 which can be spot or laser welded to side tabs 227 of top shield 220. Top shield 220 can further include recess 226, tabs 224, and tabs 228.
[0051] Tongue 280 can support ground contact 294, ground contact 297 (shown in
[0052] Contacts 240 can include contacting portions 242 and solder tails 244. Contacts 240 can be supported by top housing portion 250. Contacts 260 can include contacting portions 262, which can be located in slots (not shown) on a bottom side of tongue 280, and solder tails 264. Contacts 260 can be supported by bottom housing portion 270. Contacting portions 242 and contacting portions 262 can physically and electrically connect to corresponding contacts on a corresponding connector insert when the corresponding connector insert is inserted into front opening 212 of connector receptacle 200.
