Abstract

A heatable electric connector for preventing frosting of an electrical connector of the heatable electric connector is provided. A heating element provides indirect heating or optionally direct heating of the electrical connector. A temperature controller senses an approximate temperature of the electrical connector and compares the connector temperature to a set-point temperature and either turns on or off the heating element thereby ensuring that the electrical connector is of a suitable temperature so that frost does not form and/or accumulate on the connector.

Claims

1. A heatable connector for connection with a device, the connector comprising:

an electrical connector;

a heating element for heating the electrical connector;

a temperature sensing element for determining a connector temperature; and

a control device in communication with the heating element for activating the heating element for heating the electrical connector.

2. The connector of claim 1, wherein the control device is in communication with the temperature sensing element, the control device for comparing the connector temperature to a set temperature and cycling the heating element on when the connector temperature is below the set temperature and off when the connector temperature is at or above the set temperature.

3. The connector of claim 1, wherein the heating element comprises one or more resistors.

4. The connector of claim 3, wherein the heating element is one or more 1 K 5% 250 mW resistors driven by 15V (net 4.5 W).

5. The connector of claim 1, wherein the temperature control device comprises a thermistor for sensing the connector temperature selected from the group consisting of an NTC thermistor and a PTC thermistor.

6. The connector of claim 1, wherein the temperature control device comprises a temperature controller for comparing the connector temperature and the set temperature.

7. The connector of claim 6, wherein the temperature controller is selected from the group consisting of a hysteric temperature controller and a non-hysteric temperature controller.

8. The connector of claim 1, further comprising an ambient temperature sensor for measuring an ambient temperature.

9. The connector of claim 1, wherein the heating element is a copper trace embedded in a circuit board around at least a portion of the electrical connector.

10. The connector of claim 1, wherein the electrical connector is selected from the group consisting of:

a compliant connector and a non-compliant connector.

11. The connector of claim 1, wherein the electrical connector is a pogo connector.

12. The connector of claim 1, wherein the temperature control device is connected to the heating element by a switch operated by the temperature control device.

13. The connector of claim 1, wherein the temperature control device comprises a power supply for operating the heating element and a switch for enabling power to be sent to the heating element.

14. The connector of claim 1, wherein the electrical connector and the temperature control device are implemented into a printed circuit board.

15. The connector of claim 1, wherein the heating element is mounted directly to the electrical connector and is electrically connected to the controller.

16. The connector of claim 1, wherein the heating element is placed at least substantially around the electrical connector.

17. The connector of claim 1, wherein the temperature sensor is in proximity to the electrical connector for sensing the connector temperature.

18. The connector of claim 1, wherein the temperature sensor is mounted directly to the contacts of the electrical connector.

19. An electronic device comprising a heatable electric connector, the heatable electric connector comprising:

an electrical connector;

a heating element for heating the electrical connector;

a temperature sensing element for determining a connector temperature; and

a control device in communication with the heating element for activating the heating element for heating the electrical connector.

20. The device of claim 19, wherein the control device is in communication with the temperature sensing element, the control device for comparing the connector temperature to a set temperature and cycling the heating element on when the connector temperature is below the set temperature and off when the connector temperature is at or above the set temperature.

21. The device of claim 19, wherein the heating element comprises one or more resistors.

22. The device of claim 19, wherein the heatable electric connector is connected to a printed circuit board, and the heating element comprises a copper trace embedded in the circuit board around at least a portion of the electrical connector.
