Ramped battery contact systems and methods
The present disclosure relates to ramped battery contacts for a battery pack that support multiple engagement methods to devices, such as terminals, recharging stations, and the like. The battery pack can make a connection with a terminal one way and with a recharging station with another. Advantageously, the multiple engagement methods allow for different connectors for the different applications associated with the terminal and the recharging station. In an exemplary embodiment, the ramped battery contacts enable a terminal to connect to a battery pack through pogo-pin contacts to prevent disconnections in a rugged environment. The same ramped battery contacts can connect to a recharging station with leaf spring contacts through a swiping action that makes insertion and removal of the battery pack in the recharger quicker and easier.
1. A system supporting multiple battery connection modes, comprising:
a battery comprising battery contacts, wherein the battery contacts comprise a ramped configuration of a plurality of contacts and a contact pad, wherein the plurality of contacts and the contact pad extend along a ramp plane such that the plurality of contacts are disposed on a recessed portion of the contact pad;
a first device comprising pogo pin contacts; and
a second device comprising leaf spring contacts;
wherein the ramped configuration provides different connection modes comprising a first connection mode between the battery and the first device and a second connection mode between the battery and the second device and further wherein in the first connection mode the first device engages the plurality of contacts from a substantially perpendicular direction relative to the ramped configuration, and in the second connection mode the second device engages the plurality of contacts from a substantially parallel direction relative to the ramped configuration.
2. The system of claim 1 , wherein the ramped configuration comprises a bottom plane, a top plane, and the ramp plane interconnecting the bottom plane and the top plane, wherein the ramp plane is at an angle relative to the bottom plane and the top plane, and wherein the bottom plane and the top plane are substantially parallel.
3. The system of claim 1 , wherein the plurality of contacts and the contact pad extend along each of the bottom plane, the top plane, and the ramp plane.
4. The system of claim 2 , wherein the plurality of contacts is slightly recessed relative to the contact pad.
5. The system of claim 2 , wherein the ramped configuration connects to a device with the pogo pin contacts in a first mode and connection to a device with the leaf spring contacts in a second mode.
6. The system of claim 5 , wherein the device with pogo pin contacts comprises a terminal device configured to attach and detach with the battery, and the device with leaf spring contacts comprises a charger configured to attach and detach with the battery.
7. The system of claim 5 , wherein the ramped configuration of the battery contacts is adapted to engage with the first device comprising the pogo pin contacts by sliding the pogo pin contacts into the ramped configuration substantially perpendicular to the bottom plane, the top plane, and the ramp plane such that the bottom plane, the top plane, and the ramp plane form a landing pad providing different compression actions to the pogo pin contacts; and
wherein the ramped configuration of the battery contacts is adapted to engage with the second device comprising the leaf spring contacts the second device comprising the leaf spring contacts engages with the ramped configuration of the battery contacts by swiping the leaf spring contacts into the bottom plane, the top plane, and the ramp plane substantially parallel to the bottom plane, the top plane, and the ramp plane such that the leaf spring contacts first engage from the bottom plane to the ramp plane to the top plane.
8. The system of claim 7 , wherein the plurality of contacts is slightly recessed relative to the contact pad, and wherein the leaf spring contacts engage the bottom plane, the top plane, and the ramp plane without damaging the housing.
