Abstract

A dummy battery device for testing an electronic device having a battery cavity, which includes a connector, comprises: a main structure shaped and dimensioned so as to fit in the battery cavity of the electronic device; and a head structure configured to be detachably and moveably connected to the main structure, the head structure having contacts for electrically connecting the connector of the battery cavity once the main structure is received in the battery cavity of the of the electronic device, and cables extending therefrom, the cables being electrically connected to the contacts of the head structure.

First claim

What is claimed is:

1. A dummy battery device for testing an electronic device having a battery cavity, the battery cavity comprising a connector therein, the dummy battery device comprising:
a main structure shaped and dimensioned so as to fit in the battery cavity of the electronic device,
wherein the main structure further comprises a main portion and an adjustable portion, the adjustable portion extending from one sidewall of the main portion, and
wherein the adjustable portion comprises a bracket and springs attached thereto; and

a head structure configured to be detachably and moveably connected to the main structure, the head structure having contacts for electrically contacting the connector of the battery cavity once the main structure is received in the battery cavity of the electronic device, and cables extending therefrom, the cables being electrically connected to the contacts of the head structure.

2. The dummy battery device of claim 1 , wherein the adjustable portion is slidingly received into a chamber extending inwardly from the one sidewall of the main portion and the dummy battery device further comprises at least one spring located in the chamber.

3. The dummy battery device of claim 1 , wherein the bracket and the springs are attached in a permanent manner.

4. The dummy battery device of claim 1 , wherein the bracket and the springs are detachably attached to each other.

5. The dummy battery device of claim 1 , wherein the bracket is u-shaped.

6. The dummy battery device of claim 2 , wherein the springs are configured to push the adjustable portion outwardly to adjust a length of the dummy battery device so that the dummy battery device is held firmly in the battery cavity, once the dummy battery device is placed in the cavity.

7. The dummy battery device of claim 1 , wherein the main structure is made of material selected from one of plastic, metal and composite material with a strong stiffness.

8. The dummy battery device of claim 1 , wherein ends of the cables have connectors for connecting to measurement devices and a power supply device.

9. The dummy battery device of claim 1 , wherein the main structure and the head structure have a complementary joint mechanism.

10. The dummy battery device of claim 9 , wherein the main portion comprises a socket located on a first sidewall and the head structure comprises a projection extending from a bottom surface of the head structure, the projection entering the socket to provide for a dovetail joint mechanism.

11. The dummy battery device of claim 9 , wherein the main portion comprises a projection located on a first sidewall and the head structure comprises a socket along a bottom surface of the head structure, the projection entering the socket to provide for a dovetail joint mechanism.

12. The dummy battery device of claim 10 , wherein the projection slides along a length of the first sidewall on which the socket is located in order to adjust to different battery contact positions.

13. The dummy battery device of claim 10 , wherein the projection comprises a magnet and wherein the socket is made of iron so that when the projection enters the socket, the head structure can be stopped at variable positions on the socket.

14. The dummy battery device of claim 10 , wherein the projection comprises a probe which can be extended so as to create a friction force between the projection and the socket in order to stop the head structure at variable positions on the socket.

15. The dummy battery device of claim 1 , wherein the head structure has the same number of contacts as the number of contacts defined on the connector of the cavity of the portable electronic device.

16. A method for testing an electronic device having a removable battery cavity which includes a connector therein, the method comprising:
connecting a dummy battery device to the connector in the cavity, the dummy battery device comprising:
a main structure shaped and dimensioned so as to fit in the battery cavity of the electronic device,
wherein the main structure further comprises a main portion and an adjustable portion, the adjustable portion extending from one sidewall of the main portion, and

wherein the adjustable portion comprises a bracket and springs attached thereto; and
a head structure configured to be detachably and moveably connected to the main structure, the head structure having contacts for electrically connecting the connector of the battery cavity once the main structure is received in the battery cavity of the portable electronic device, and cables extending therefrom, the cables being electrically connected to the contacts of the head structure; and connecting the cables extending from the head structure to at least one of a measurement device and power supply.
