Compressible contacts for interfacing charger
View Patent ↗A rechargeable device is disclosed. The rechargeable device may include an enclosure, a rechargeable battery cell, a constellation assembly, and charging circuitry. The enclosure may include a receptacle defining a longitudinal opening into the enclosure. The constellation assembly may include a diaphragm, a puck, and a contact point affixed to the puck and configured to engage an electrode of a charging pad surface. The charging circuitry may be configured to charge the battery cell based on electrical power received from the charging pad surface via the contact point. The receptacle may further permit movement of the puck and the affixed contact point along the longitudinal opening.
1. A rechargeable device, comprising:
an enclosure comprising a receptacle defining a longitudinal opening into the enclosure;
at least one rechargeable battery cell in the enclosure;
a constellation assembly comprising a diaphragm, a puck, and a contact point affixed to the puck and configured to engage an electrode of a charging pad surface; and
recharging circuitry configured to charge the at least one battery cell based on electrical power received from the charging pad surface via the contact point;
wherein the receptacle permits movement of the puck and the affixed contact point along the longitudinal opening.
2. The rechargeable device of claim 1 , wherein the receptacle is filled with a resilient potting material that exerts a spring force upon the puck during longitudinal movement.
3. The rechargeable device of claim 2 , wherein one or more holes are formed in an interior portion of the potting material.
4. The rechargeable device of claim 1 , further including a spring that exerts a spring force upon the puck during longitudinal movement.
5. The rechargeable device of claim 1 , wherein the diaphragm exerts a spring force upon the puck during longitudinal movement.
6. The rechargeable device of claim 1 , further comprising a first wall that extends from the puck and mates with a second wall of the receptacle.
7. The rechargeable device of claim 6 , further comprising a stop that extends radially from a distal end of the first wall and beyond the second wall, wherein the stop prevents over extension of the puck from the receptacle.
8. The rechargeable device of claim 6 , wherein the enclosure comprises an internal surface that extends over the longitudinal opening of the receptacle and obstructs a distal end of the first wall to prevent over compression of the puck into the receptacle.
9. The rechargeable device of claim 1 , further comprising a stop that radially extends from the puck beyond the receptacle and prevents over compression of the puck into the receptacle.
10. The rechargeable device of claim 1 , further comprising:
a first wall that extends from the puck and mates with a second wall of the receptacle;
a resilient arm that extends from the first wall and beyond the second wall of the receptacle; and
a catch at a distal end of the resilient arm, wherein the catch is configured to engage a surface of the second wall and prevent over extension of the puck from the receptacle.
11. A rechargeable device, comprising:
an enclosure comprising a receptacle defining a longitudinal opening into the enclosure;
at least one rechargeable battery cell in the enclosure;
a puck;
a first wall extending from the puck and into the longitudinal opening of the receptacle;
a contact point affixed to the puck and configured to engage an electrode of a charging pad surface; and
charging circuitry configured to charge the at least one battery cell based on electrical power received from the charging pad surface via the contact point;
wherein the receptacle permits longitudinal of the first wall, puck, and the affixed contact point.
12. The rechargeable device of claim 11 , wherein the receptacle is filled with a resilient potting material that exerts a spring force upon the puck during longitudinal movement.
13. The rechargeable device of claim 12 , wherein one or more holes are formed in an interior portion of the potting material.
14. The rechargeable device of claim 11 , further including a spring that exerts a spring force upon the puck during longitudinal movement.
15. The rechargeable device of claim 11 , wherein the first wall mates with a second wall of the receptacle.
16. The rechargeable device of claim 15 , further comprising a seal between the first wall and the second wall.
17. The rechargeable device of claim 11 , further comprising a stop that extends radially from a distal end of the first wall and beyond a second wall of the receptacle, wherein the stop prevents over extension of the puck from the receptacle.
18. The rechargeable device of claim 11 , wherein the enclosure comprises an internal surface that extends over the longitudinal opening of the receptacle and obstructs a distal end of the first wall to prevent over compression of the puck into the receptacle.
19. The rechargeable device of claim 11 , further comprising a stop that radially extends from the puck beyond the receptacle and prevents over compression of the puck into the receptacle.
20. The rechargeable device of claim 11 , further comprising:
a resilient arm that extends from the first wall and beyond a distal end of the receptacle; and
a catch at a distal end of the resilient arm, wherein the catch is configured to engage the distal end of the receptacle and prevent over extension of the puck from the receptacle.
