The invention relates to the field of electrical connectivity. More particularly, the invention relates to an electrical connector, with a spring, such as a watch, that establishes a power, data, and/or ground connection between a display device and a securing device.
In the art, there is an absence of an electrical connector that is able to provide power, data, and/or ground connections, while being fabricated to be unobtrusive during use.
There is consequently a need for an electrical connector resolving any or all of the foregoing issues. Further there is a need for an electrical connector that fits between a display device and a securing device, while providing power, data, and/or ground connections as necessary.
Electrical connectivity is an important component in the use of such display devices as smartwatches and other portable and wearable electronic devices. These display devices may be paired with a securing device, such as a strap, that provides additional functionalities, for example power or data. In such cases, the display device and the securing device must be electrically connected. Exemplary configurations of securing devices and display devices are disclosed in U.S. patent application Ser. No. 14/827,215, with a filing date of Aug. 14, 2015, which is incorporated herein by reference in its entirety. An electrical connection between the display and securing devices may allow power and/or data to flow between the display device and the securing device.
Accordingly, herein is provided an improved electrical connector and an improved electrical connector with a spring. The connector creates both a physical attachment connection as well as an electrical connection between two devices. An electrical connector may have a spring that can be used to provide a consistent power, data, and/or ground connection between a display device and a securing device. An electrical connector may use a spring that allows for multiple electrical (power and/or data) connections. An electrical connector may have multiple connections at a single physical location via concentric contact points that are insulated from one another. An electrical connector may use a spring that provides a consistent power, data, and/or ground connection between a display device and a securing device that further includes a side interface capable of providing an additional power or data connection.
In an exemplary configuration, the electrical connector comprises an outer casing terminating in a cap and a connection pin having an uncovered portion and a portion covered by the outer casing. A spring is operably attached to the connection pin. The uncovered portion of the connection pin establishes an electrical connection between a securing device and a display device and the outer casing establishes a ground connection between the securing device and the display device. While the electrical connector has established that connection, the securing device is able to rotate relative to the display device while maintaining the electrical connection and the ground connection between the securing device and the display device. In variations of this configuration, the electrical connector may include a substructure for attaching it to the securing device. The electrical connector may also include a separate ground connection band, in which case, the outer casing will act as the insulator. The electrical connector may additionally include a quick-release lever for the improved attachment and release of the electrical connector from the display device.
In another configuration of the electrical connector, there are two different connection pins. The first connection pin is partially covered by a first pin insulator that terminates in a first cap. A spring is operably attached to the first connection pin. The second connection pin is partially covered by a second pin insulator that also terminates in a second cap. A spacer rests between the two caps, separating the two connection pins. The uncovered portion of the first connection pin establishes an electrical or ground connection between a securing device and a display device and the uncovered portion of the second connection pin establishes an electrical or ground connection between the securing device and the display device.
In variations of this configuration, the two connection pins are removably attached to the securing device and are arranged linearly to point in substantially opposite directions. In other variation of this configuration, the first connection pin and the second connection pin are removably connected to the display device such that the securing device is able rotate relative to the display device while maintaining the power or data connection and the ground connection between the securing device and the display device. In certain other variations of this configuration, the spacer may be an insulator or a hollow molded space between the first cap and the second cap of the pin insulators.
In yet another configuration of the electrical connector, there are two connection pins and a side interface. The first connection pin is partially covered by a first pin insulator that terminates in a first cap. A spring is operably attached to the first connection pin. The second connection pin is partially covered by a second pin insulator that also terminates in a second cap. The side interface is located between the first connection pin and the second connection pin along the longitudinal axis of the electrical connector. A spacer rests between the two caps, separating the two connection pins and the side interface from each other. The uncovered portion of the first connection pin establishes an electrical or ground connection between a securing device and a display device and the uncovered portion of the second connection pin establishes an electrical or ground connection between the securing device and the display device. The side interface establishes an additional electrical or ground connection between the securing device and the display device.
In variations of this configuration, the first connection pin, the second connection pin, and the side interface are removably connected to the display device such that the securing device is able rotate relative to the display device while maintaining the power and/or data connection and the ground connection between the securing device and the display device. In other variations of this configuration, the electrical connector may include a substructure for attaching the electrical connector to the securing device. This substructure may be a flange, tab, insert, or other coupling device. In certain other variations of this configuration, the spacer may be an insulator or a hollow molded space between the first cap and the second cap of the pin insulators. In yet other variations of this configurations, the side interface may be a lobe that protrudes from the longitudinal axis of the electrical connector. In that variation, the first connection pin, the second connection pin, and the lobe are removably connected to the display device such that the securing device is able rotate relative to the display device while maintaining the electrical and the ground connections between the securing device and the display device.
In yet another configuration of the electrical connector, there are concentric connection pins. The first connection pin is partially covered by a first pin insulator. A spring is operably attached to the first connection pin. A concentric pin encircles the first pin insulator. The concentric pin is partially covered by a second insulator. A ground casing the covers the second insulator. In this configuration, the uncovered portion of the central connection pin establishes an electrical connection between a securing device and a display device, the uncovered portion of the first concentric pin establishes an electrical connection between the securing device and a display device, and the ground casing establishes a ground connection between the securing device and the display device.
In variations of this configuration, the concentric pin electrical connector is removably attached to the securing device, and the connection pin, the first concentric pin, and ground casing are removably connected to the display device such that the securing device is able rotate relative to the display device while maintaining the electrical connection and the ground connection between the securing device and the display device. In other variations of this configuration, the concentric pin electrical connector has a substructure for attaching the connector to the securing device. The substructure may be a flange, a tab, an insert, or other coupling device. In yet other configurations, the concentric pin electrical connector may include a quick-release lever for the improved attachment and release of the electrical connector from the display device.
These will become more readily apparent when reference is made to the following description, taken in conjunction with the accompanying drawings.
A more complete appreciation of the invention and many of the attendant advantages thereof will be readily obtained as the same becomes better understood by reference to the following detailed description when considered in conjunction with the accompanying drawings, wherein:
In describing aspects of the invention illustrated in the drawings, specific terminology will be resorted to for the sake of clarity. However, the invention is not intended to be limited to the specific terms so selected, and it is to be understood that each specific term includes all technical equivalents that operate in similar manner to accomplish a similar purpose. Several aspects of the invention are described for illustrative purposes, it being understood that the invention may be embodied in other forms not specifically shown in the drawings.
As is shown and described, the electrical connector 100 is configured to make both a physical connection for attachment as well as an electrical connection between a display device (e.g. a watch, a wristband, a fitness tracker, or a smart necklace) and a securing device (e.g. a strap or a neckband).
In
The uncovered portion 112 of the connection pin 110 is designed to push against a point of contact on the display device, creating an electrical connection. In that installed position, the uncovered portion 112 pushed against the point of contact, the covered portion 114 is positioned to compress the spring 120, resulting in the initiation of an electrical connection, which may involve a transfer of power or data between the display device and the securing device. In general, the electrical connection from the display device passes from the connection pin 110, through the spring 120, and through the cap 140. The cap 140 may be connected to electronic components or batteries (not shown) in the securing device. These electrical connections between the cap 140 and the components of the securing device may comprise leads, soldering metals, or other ways of connection to the securing device.
In certain configurations, the outer casing 130 of the electrical connector 100 may act as a ground connection. In those configurations, the outer casing 130 may include a ground layer molded between an inner insulator that separates the ground connection from the connection pin 110 and an outer layer that encloses the electrical connector 100. This sandwiched ground layer of the outer casing 130 is responsible for establishing the ground connection between the display device and the securing device.
In certain installations of the electrical connector 100′, the outer casing 130′ may serve as the ground connection. In other installations of the electrical connector 100′, there may exist a separate ground connection band between the outer casing 130′ and the pin insulator 160′. The ground connection band or the outer casing 130′, when used as a ground connection, may have a further substructure used to attach the electrical connector 100′ to a securing device, while also establishing a ground connection with the securing device. In
The springless electrical connector 100′ is contemplated as being a point of both physical and electrical connection between a securing device, such as a smartwatch band, and a display device, such as a smartwatch. In some cases, the electrical connector 100′ may be used in conjunction with electrical connector 100, such that the two connectors together establish separate points of connection between a securing device and a display device. In such a configuration, the connectors 100 and 100′ can each establish electrical connections. In fact, each can establish multiple electrical connections between a securing device and a display device.
In the exploded isometric view of the concentric pin electrical connector 200 in
The first concentric pin 240 is comprised of an uncovered portion 242 and a covered portion 244. The first concentric pin 240 may also include a quick release lever 246 that can be used to move the first concentric pin 240 by compressing the spring 220, thereby allowing for the concentric pin electrical connector 200 to be removed from the display device. It will be readily apparent to one of ordinary skill in the art that the quick-release lever 246, shown in
The uncovered portion 242 of the first concentric pin 240 is situated around the uncovered portion 212 of the connection pin 210 such that when the connection pin 210 establishes an electrical connection between the display device and the securing device, the first concentric pin 240 does so as well. The covered portion 244 of the first concentric pin 240 is covered with a second insulator 250. This second insulator 250 acts as a casing around the covered portion 244, such that a first concentric pin 240 is electrically isolated from the ground casing 260.
The second insulator 250 is covered by a ground casing 260. The second insulator functions to maintain electrical separation between the ground casing 260 and the first concentric pin 240. The ground casing 260 is situated around the second insulator 250 such that when the connection pin 210 and first concentric pin 240 establish an electrical connection between the display device and the securing device, the ground casing 260 establishes a ground connection between the display device and the securing device. As shown in
The external surface of the electrical connector 200 is formed by an insulator casing 270, which wraps around the ground casing 260. The insulator casing 270 may have an internal protrusion 272 that acts as a mechanical stop for the spring 220, against which it can compress. At the end distal to the point of contact for the connector pin 210, a cap 280 is operably attached to the insulator casing 270. The cap 280 is further comprised of a base 282 and one or more contacts 284, from which the one or more contacts 284 extend towards the connection pin 210. In the other direction, the one or more contacts 284 may also extend away from the connection pin 210 to allow for attachment and electrical connection to the securing device. The one or more contacts 284 may also be machined or molded to bend radially inward as they extend towards the connection pin 210.
An exemplary operation of concentric pin electrical connector 200 is shown in
When the concentric connector 200 is in the resting state position, there is no electrical connection between the connection pin 210 and the one or more contacts 284. This provides a useful feature in that it electrically isolates the connection pin 210 from the securing device and prevents any shorts, drainage of the battery, or electrical damage to the device while in the resting position. This isolation prevents static electrical charges originating from the connection pin 210 from damaging or shorting the components. When compressed, usually just prior to installation, the concentric pin electrical connector 200 is in a compressed state and the spring 220 is compressed more than it would be in either the resting state or installed state. In the installed state, the spring 220 is in between the state of rest and the state of compression.
The cap 280, located on the distal end of the electrical connector 210, is stationary, preferably molded to the insulator casing 270. From the base 282 of the cap 280, one or more contacts 284 extend along the longitudinal axis of the concentric pin electrical connector 200, towards the connection pin 210.
The one or more contacts 284 preferably extend into a hollow inner chamber 290 within the concentric pin electrical connector 200. The one or more contacts 284 may be molded or machined in such a manner that they extend into the center of the hollow inner chamber 290, allowing for the connection pin 210 to make contact with them when the spring 220 is compressed. The hollow inner chamber 290 is preferably separated from a hollow spring chamber 292 by an internal protrusion 272 of the insulator casing 270. The internal protrusion 272 may be a tab, a flange, or a cylindrical disk, or other means. The internal protrusion 272 typically operates as a mechanical stop for the spring 220. It will be readily apparent that any of the other concentric insulator layers of the concentric pin electrical connector 200 may be molded to form the internal protrusion 272, so long as the structure operates as a mechanical stop for the spring 220. As shown in
In the configuration shown in
In general, the electrical connection between the display device and the securing device comprises the connection pin 210, the spring 120, and the one or more contacts 284, which may have leads or other ways of connecting to the securing device. Each of these components are connected to the next in a manner that allows electrical signals to pass. When an electrical signal is transmitted from the display device to the securing device, the signal takes the following path: the connection pin 210 to the one or more contacts 284 to the securing device. Typically, electrical signals or power can pass through these components in either direction.
When in the fully compressed position (not shown), the covered portion 214 of the connection pin 210 the concentric pin electrical connector 200 is retracted so that its distal end moves beyond the one or more contacts 284 into the hollow inner chamber 290.
It will be readily apparent to one of ordinary skill in the art that the concentric pin configurations of
An advantage of the electrical connector 100, 100′, 200 disclosed herein is that, in all of the disclosed configurations, the securing device to which the electrical connector is attached remains capable of rotating about the display device while maintaining an electrical connection between the two devices.
In the system exemplary configuration 300 of
As shown in
It will be readily apparent to one of ordinary skill in the art that any of the configurations of electrical connectors 100, 100′, 200 may be employed as disclosed in
In
For each electrical connector 100, 100′, 200, the display device has a connection point 332 for the connection pin 110, 110′, 210 of the electrical connectors 100, 100′, 200. The connection point 332 is the point of contact for the connection pin 110, 110′, 210, resulting in the electrical connection between the securing device and the display device. The connection point 332 may connect power, data, or the ground. Surrounding the connection point 332 is an insulation band 334. The insulation band 334 keeps the plurality of electrical and/or ground connections separated, preventing shorts and damage to the display device or securing device. Surrounding the insulation band 334 is a concentric connection band 336. The concentric connection band 336 provides an additional point of contact for the concentric pin 240 of the concentric pin electrical connector 200 or for the outer casing 130, 130′ of electrical connectors 100, 100′, which is responsible for the ground connection. It will be readily apparent to one of ordinary skill in the art that additional concentric connection bands may be present, as long as they are separated by insulation bands that prevent shorts or damage to the display device 330 or the securing device 320.
The display device 330 may also have a plurality of mating interfaces 338 running along a face of the display device. These mating interfaces 338 are designed to contact or pair with the side interface 246 of electrical connector 200. Connection of the side interface 246 of electrical connector 200, as explained with respect to
The foregoing description and drawings should be considered as illustrative only of the principles of the electrical connector. The electrical connector may be configured in a variety of shapes and sizes and is not intended to be limited by the shown configurations. Numerous applications of the invention will readily occur to those skilled in the art. Therefore, it is not desired to limit the electrical connector to the specific examples disclosed or the exact construction and operation shown and described. Rather, all suitable modifications and equivalents may be resorted to, falling within the scope of this disclosure.
