Method of establishing physical and electrical connections between a battery and a circuit
A method of establishing a physical and electrical connection between a battery and a circuit board are described. The methods include applying a texture formed from conductive material to a portion of a battery exterior surface. The texture is a region populated by a plurality of protrusions. Protrusions may be configured to partially perforate and lodge within a contact surface secured to a circuit board. The battery with a texture surface may be pressed against the circuit board resulting in perforation of the contact surface by the region of protrusions. The methods may result in a battery and circuit board in electrical communication, and suitable for use within a variety of medical devices.
1. A battery, comprising:
a textured surface including a region of raised protrusions, the raised protrusions on an electrically conductive portion of an exterior of the battery, wherein the textured surface is configured to at least partially perforate a contact surface of a circuit board and engage in a physical and electrical connection with the contact surface of the circuit board.
2. The battery of claim 1 , wherein the raised protrusions have a spike shape.
3. The battery of claim 1 , wherein the raised protrusions have a barbed or conical shape.
4. The battery of claim 1 , wherein the textured surface is disposed on a battery terminal.
5. The battery of claim 1 , wherein the textured surface is integral to a battery casing.
6. The battery of claim 1 , wherein the textured surface is directly affixed to the battery.
7. The battery of claim 1 , wherein the textured surface is secured to a portion of the exterior of the battery.
