Abstract

A battery connector system for use with a powered ride-on vehicle for children, where the vehicle includes an electric motor adapted to drive one or more wheels of the vehicle and a wiring harness adapted to convey power to the motor. The battery connector system includes a plug attached to the wiring harness and has a case substantially enclosing positive and negative plug contacts. The plug further includes a normally-open switch interposed between a switched one of the plug contacts and the wiring harness with the switch having an actuator by which the switch may be closed, whereby the switched plug contact is not electrically connected to the wiring harness until the switch is closed. The system further includes a battery including positive and negative terminals and a socket including housing structure adapted to fit together with the plug case and substantially enclosing positive and negative socket contacts which are respectively connected to positive and negative terminals of the battery. The housing structure is adapted to position the positive and negative socket contacts to respectively engage the positive and negative contacts on the plug when the housing structure and case are fit together. The battery connector also includes a key adapted to engage the actuator and close the switch when the housing structure and case are fit together. A portion of the socket may serve as a charging jack for the battery.

Claims

1. A battery connector system for use with a powered ride-on vehicle for children, the vehicle including an electric motor adapted to drive one or more wheels of the vehicle and a wiring harness adapted to convey power to the motor, the battery connector system comprising:

a plug attached to the wiring harness and including a case substantially enclosing positive and negative contacts, the plug further including a normally-open switch interposed between a switched one of the contacts and the wiring harness, the switch having an actuator by which the switch may be closed, whereby the switched contact is not electrically connected to the wiring harness until the switch is closed;

a battery including positive and negative terminals; and

a socket including housing structure adapted to fit together with the case and substantially enclosing positive and negative contacts connected to positive and negative terminals of the battery, respectively, the housing structure being adapted to position the contacts to engage the positive and negative contacts on the plug when the housing structure and case are fit together, the socket further including a key adapted to engage the actuator and close the switch when the housing structure and case are fit together.

2. The system of claim 1, wherein the socket housing structure further includes a partition disposed between the positive and negative contacts to prevent accidental shorting therebetween.

3. The system of claim 2, wherein the socket includes a plug-receiving pocket, and the partition divides the pocket into separate portions.

4. The system of claim 3, wherein the key structure is formed on the partition.

5. The system of claim 1, wherein the socket further includes a charging jack adapted to receive a charging probe.

6. The system of claim 5, wherein the charging jack further includes positive and negative contact arms connected to the positive and negative terminals of the battery, respectively, and adapted to engage corresponding contact plates formed on the charging probe to convey power from the probe to the battery.

7. The system of claim 1, wherein the battery has a plurality of cells, the system fuirther including a circuit breaker disposed between two of the plurality of cells.

8. The system of claim 1, wherein the battery includes a cover and the socket is mounted to the battery under the cover.

9. The system of claim 1, wherein the key prevents the plug from being inserted into the socket with incorrect polarization.

10. The system of claim 1, wherein the key is positioned to actuate the switch only when the plug is substantially fully engaged in the socket.

11. The system of claim 1, wherein the socket housing structure is a single piece which positions both contacts and the key to receive the plug.

12. A battery system for use in a powered ride-on vehicle for children, the vehicle having a wiring system with a plug including a case enclosing spaced-apart positive and negative blade receptacles and a normally open switch disposed between one of the receptacles and the wiring system to connect the receptacle with the wiring system upon actuation of the switch, the switch having an actuator located between the blade receptacles with the case having a keyway allowing access to the actuator, the battery system comprising:

a battery with positive and negative terminals;

positive and negative electrical leads connected to the positive and negative terminals of the battery, respectively, to deliver power therefrom, each lead including a blade lug at an end of the lead opposite the battery, the lugs being adapted to fit into corresponding ones of the positive and negative receptacles;

a key adapted to be positioned between the blade lugs to project into the keyway in the plug case and adapted to actuate the switch when projecting into the keyway; and

housing structure surrounding the blade contacts sufficiently to prevent the blade contacts both from inadvertently contacting each other and from simultaneously being contacted by a straight surface, the housing structure further including at least one opening configured to receive a portion of the plug case whereby the blade lugs can engage the blade receptacles.

13. The system of claim 12, wherein the housing structure includes a partition disposed between the blade contacts.

14. The system of claim 13, wherein the key is mounted to the housing structure.

15. The system of claim 14, wherein the key is mounted to the partition.

16. The system of claim 12, wherein the battery system further includes a charging jack disposed within the housing structure, the charging jack including positive and negative contact arms connected to the positive and negative blade contacts, respectively, and adapted to engage contact plates formed on a charging probe.

17. The system of claim 12, wherein the housing structure is disposed within a cover attached to the top of the battery.

18. The system of claim 17, wherein the cover includes an alignment notch adapted to receive an alignment member formed on the plug case to thereby provide a user with a visual indication of proper plug orientation.

19. A battery connector system for a powered ride-on vehicle for children with the vehicle having an electrical system, the battery connector system comprising:

a plug on the vehicle, wherein the plug includes a case holding a pair of laterally spaced receivers and a normally-open switch having an actuator, the case further having a keyway located between the receivers and permitting access to the actuator, the receivers being electrically connected to the vehicle electrical system with one of the receivers being connected through the switch, whereby the switch establishes communication between the other receiver and the vehicle electrical system when the switch is closed;

a battery with positive and negative terminals;

a pair of contacts, wherein each contact is coupled to a respective one of the terminals and is configured to engage a respective one of the receivers to establish communication between the battery and the vehicle electrical system; and

a housing structure at least partially enclosing the contacts so that the contacts can be positioned in a laterally spaced relationship to engage the receivers, wherein the housing structure includes a partition positioned between the contacts and a key shaped to be received within the keyway to close the switch when the receivers and contacts engage each other, thereby establishing communication between the battery and the vehicle electrical system.

20. The system of claim 19, wherein the housing structure includes a pair of laterally spaced partitions extending between the contacts to define a pocket extending generally parallel to the contacts, with the key extending within the pocket.

21. The system of claim 20, further including a charging jack disposed within the pocket.

22. The system of claim 19, wherein the housing structure includes a pocket adapted to receive a portion of the plug, and the pocket includes a plurality of laterally spaced and longitudinally extending ribs that guide and reduce the friction between the plug and the pocket as the plug is received in the pocket.

23. The system of claim 19, wherein the key prevents the receivers from being engaged with the contacts with incorrect polarization.
