Abstract

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.

First claim

What is claimed is:

1 . A battery, comprising:
a textured surface on an electrical conductive portion of an exterior of the battery.

2 . The battery of claim 1 , wherein the textured surface is a region of protrusions.

3 . The battery of claim 1 , wherein the textured surface is a plurality of pointed protrusions.

4 . The battery of claim 3 , wherein the pointed protrusions have a barbed or conical shape.

5 . The battery of claim 1 , wherein the textured surface is disposed on a battery terminal.

6 . The battery of claim 1 , wherein the textured surface is integral to a battery casing.

7 . The battery of claim 1 , wherein the textured surface is directly affixed to the battery.

8 . The battery of claim 1 , wherein the textured surface is secured to a portion of the exterior of the battery.

9 . A method of securing a battery to a circuit board, comprising:
forming a textured surface having a plurality of surface elements on a portion of a battery exterior; and pressing the textured surface of the battery exterior onto a contact surface causing the plurality of surface elements to engage the contact surface.

10 . The method of claim 9 , wherein the textured surface comprises a region of raised protrusions.

11 . The method of claim 10 , wherein the raised protrusions have a spike shape.

12 . The method of claim 10 , wherein the raised protrusions have a barbed or arrowhead shape.

13 . The method of claim 9 , wherein the textured surface is applied to battery terminals.

14 . The method of claim 9 , wherein the textured surface is constructed from a conductive material, such that engaging the surface elements with the contact surface places the battery in electrical communication with the circuit board.

15 . The method of claim 9 , wherein the one or more contact surfaces comprise a copper layer and a gold layer.

16 . The method of claim 15 , wherein the copper layer, gold layer and protective polymer layer are disposed in a stacked configuration.

17 . The method of claim 9 , further comprising applying an adhesive to one or both of the textured surface and the contact surface prior to pressing the textured surface onto the contact surface.

18 . The method of claim 17 , wherein applying an adhesive further comprises: placing an adhesive film between the textured surface and the contact surface.

19 . A battery, comprising surface texture means for electrically connecting the battery to a contact surface of a circuit board.

20 . The battery of claim 19 , wherein the surface texture means for electrically connecting the battery to a contact surface also physically connects the battery to the contact surface.

21 . The battery of claim 19 , wherein the surface texture means of electrically connecting the battery to a contact surface wholly or partially perforates the contact surface.
