Abstract

Methods and apparatuses supporting an electrical connection in a manner that eliminates or reduces a danger of electrical sparking are disclosed. A sparkless electrical connector has a conductor, configured to provide flow of electricity between an electrical source and a load, and a resistive element, operatively coupled to the conductor, to resist flow of electricity during a state of partial connection with the electrical source or the load. The resistive element may be not in contact with a terminal of the source or load during a state of full connection. The resistive element may be a coating of an anodized material on a pin of the conductor. The coating provides a resistance sufficient to prevent sparking during connection of the conductor and at least one of the electrical source and the load. Techniques disclosed herein benefit users and manufacturers in the areas of safety, cost, simplicity, and reliability.

Claims (15)

1. An electrical connector comprising:

a conductor configured to provide flow of electricity between an electrical source and a load, the electrical source being a battery; and

a resistive element, operatively coupled to the conductor, to resist the flow of electricity during a state in which the connector is at least partially connected to the electrical source or the load, and wherein the resistive element is not in contact with a terminal of the electrical source or the load during a state in which the connector is fully connected to the electrical source or the load, wherein the resistive element is a coating, of an anodized material, on a pin of the conductor, the coating providing a resistance sufficient to prevent sparking during connection of the conductor and at least one of the electrical source and the load.

2. The electrical connector of claim 1 , wherein the conductor further includes:

a first pin configured to couple electrically with the electrical source; and

a second pin configured to couple electrically with the load, the second pin electrically coupled to the first pin; and

wherein the resistive element is operatively coupled to at least one of the pins.

3. The electrical connector of claim 1 , wherein the conductor includes a busbar and at least two interface components, and further wherein the resistive element is operatively coupled to at least one of the interface components.

4. The electrical connector of claim 1 , wherein the coating is at a distal half of the pin.

5. The electrical connector of claim 1 , wherein the coating covers a distal tip of the pin.

6. A method of supporting an electrical connection, the method comprising:

passing electricity from an electrical source, through a conductor of an electrical connector, to a load, the electrical source being a battery;

resisting flow of electricity at the electrical connector during a state in which the electrical connector is at least partially connected to the electrical source or the load, wherein resisting the flow of electricity includes providing an anodized coating on the connector to contact a terminal of the electrical source or the load, the coating providing a resistance sufficient to prevent sparking during connection of the conductor and at least one of the electrical source and the load; and

supporting normal flow of electricity at the electrical connector during a state in which the electrical connector is fully connected to the electrical source or the load by preventing contact of a resistive element with a terminal of the electrical source or the load.

7. The method of claim 6 , wherein the coating covers a distal tip of the connector.
