The interface may include a universal serial bus interface and may be coupled to a data isolation chip and a power isolation chip. A power controlling processor may determine how the supplied power, e.g., voltage, is supplied to other components within the infusion device. Additional circuitry within the system may provide a secure power transfer within the device to ensure user safety and ensure that a high frequency noise is properly attenuated. ## Claims ### Claim 1 An ambulatory infusion pump, comprising: a housing having a front surface and a back surface that are spaced apart and enclosed by side surfaces to define an internal cavity; an electrical connector port fitted to the housing and extending into the internal cavity, the electrical connector port operably connected to a power isolation connector and a data isolation connector disposed within the housing, the electrical connector port adapted to receive electrical power and data via a direct electrical connection, and to direct the electrical power to the power isolation connector and the data to the data isolation connector, an overmold mechanically coupled to the housing and having an upper portion and a lower portion, wherein the electrical connector port is disposed between the upper portion and the lower portion such that the overmold physically separates the electrical connector from the housing, and wherein the overmold, the housing, and the electrical connector port are configured to provide a seal preventing passage of moisture into the internal cavity; a transformer disposed within the overmold and configured to control electrical input from the electrical connector port; and a battery charger disposed within the overmold and configured to receive substantially constant output from the transformer. ### Claim 2 (depends on 1) The ambulatory infusion pump of claim 1, further comprising an electrical connector port door configured to be attached to the housing over the electrical connector port. ### Claim 3 (depends on 2) The ambulatory infusion pump of claim 2, wherein a seal is formed between the electrical connector port and the electrical connector port door. ### Claim 4 (depends on 3) The ambulatory infusion pump of claim 3, wherein the overmold comprises an insulator material having a shape determined by the power isolation connector and associated circuitry in order to meet regulatory emissions requirements for a medical device. ### Claim 5 (depends on 4) The ambulatory infusion pump of claim 4, wherein the overmold comprises a membrane. ### Claim 6 (depends on 1) The ambulatory infusion pump of claim 1, wherein the power isolation connector is electrically isolated from the data isolation connector. ### Claim 7 (depends on 1) The ambulatory infusion pump of claim 1, further comprising: a processor disposed in the housing; and a touch sensitive display screen, wherein the processor is capable of receiving inputs from the touch sensitive display screen. ### Claim 8 An ambulatory infusion pump, comprising: a housing having a front surface and a back surface that are spaced apart and enclosed by side surfaces to define an internal cavity; an electrical connector port fitted to the housing and extending into the internal cavity, the electrical connector port operably connected to a power isolation connector and a data isolation connector disposed within the housing, the electrical connector port adapted to receive electrical power and data via a direct electrical connection, and direct the electrical power to the power isolation connector and the data to the data isolation connector; an overmold mechanically coupled to the housing and having an upper portion and a lower portion, wherein the electrical connector port is disposed between the upper portion and the lower portion such that the overmold physically separates the electrical connector from the housing, and wherein the overmold, the housing, and the electrical connector port are configured to provide a seal preventing passage of moisture into the internal cavity, and wherein the power isolation connector is coupled to a power isolation circuit; a transformer disposed within the overmold and configured to control electrical input from the electrical connector port; and a battery charger disposed within the overmold and configured to receive substantially constant output from the transformer. ### Claim 9 (depends on 8) The ambulatory infusion pump of claim 8, further comprising an electrical connector port door configured to be attached to the housing over the electrical connector port. ### Claim 10 (depends on 9) The ambulatory infusion pump of claim 9, wherein a seal is formed between the electrical connector port and the electrical connector port door. ### Claim 11 (depends on 10) The ambulatory infusion pump of claim 10, wherein the overmold comprises an insulator material having a shape determined by the power isolation connector and associated circuitry in order to meet regulatory emissions requirements for a medical device. ### Claim 12 (depends on 8) The ambulatory infusion pump of claim 8, wherein the overmold is comprised of a non-conductive material. ### Claim 13 (depends on 8) The ambulatory infusion pump of claim 8, wherein the power isolation connector is electrically isolated from the data isolation connector. ### Claim 14 (depends on 8) The ambulatory infusion pump of claim 8, further comprising: a processor disposed in the housing; and a touch sensitive display screen, wherein the processor is capable of receiving inputs from the touch sensitive display screen.
