Abstract

A communication terminal, such as a handset, has a printed circuit board (PCB) sandwiched between a front cover and a back cover of the phone, and furthermore comprises at least one battery element placed between said printed circuit board and the back cover of the communication terminal. The at least one battery element and said printed circuit board are separated by a flexible and compressible partition wall. When the communication terminal is assembled, the wall provides bias between said at least one battery element and said printed circuit board.

Claims

1. A communication terminal having a printed circuit board (PCB) sandwiched between a front cover and a back cover of the communication terminal, and furthermore comprising at least one battery element placed between the printed circuit board and the back cover of the communication terminal, the at least one battery element and the printed circuit board being separated by a flexible, separate and compressible partition wall that is substantially parallel with other members in the sandwiched structure and which, when the communication terminal is assembled provides bias between the at least one battery element and the printed circuit board, the printed circuit board overlying the battery element, wherein the printed circuit board and the battery are provided as an interconnected assembly prior to the assembling of the communication terminal.

2. A communication terminal according to claim 1 wherein the partition wall is provided as a layer of foamed plastics.

3. A communication terminal according to claim 1 wherein the partition wall is provided as a layer of foam rubber.

4. A communication terminal according to claim 1 wherein the partition wall is coated with a metallic foil on the surface facing towards the printed circuit board, and wherein groups of components on the printed circuit board are surrounded by conducting walls to provide open boxes which are closed by the metallic foil on the partition wall.

5. A communication terminal according to claim 1 wherein the battery is welded or soldered to the printed circuit board of the communication terminal via flexible metallic connectors.

6. A communication terminal according to claim 1 wherein the communication terminal is a handportable phone for cellular or cordless communication.

7. A communication terminal as in claim 1 wherein the battery element is non-removably connected to the printed circuit board.

8. A communication terminal as in claim 1 wherein the battery element is separated from the printed circuit board by the partition wall over a substantial portion of its length.

9. A communication terminal having a housing including a front cover and a rear cover, and the terminal further including:

a printed circuit board having a plurality of shielding walls for providing a number of open shielding boxes;

at least one battery element for being placed between the printed circuit board and the rear cover of the communication terminal; and

a flexible, separate and compressible partition wall separating the at least one battery element and the printed circuit board and biasing the metallic foil coated on the surface of the partition wall towards the open shielding boxes, the printed circuit board overlying the battery element, wherein the printed circuit board and the battery are provided as an interconnected assembly prior to the assembly of the communication terminal.

10. A communication terminal as in claim 9 wherein the battery element is non-removably connected to the printed circuit board.

11. A communication terminal as in claim 9 wherein the battery element is separated from the printed circuit board by the partition wall over a substantial portion of its length.

12. A communication terminal having a housing including a front cover and a rear cover, and the terminal further including:

a printed circuit board having a plurality of shielding walls for providing a number of open shielding boxes;

at least one battery element being placed between the printed circuit board and the rear cover of the communication terminal; and

a flexible, separate and compressible partition wall having a metal foil coated on a surface of the partition wall, the partition wall separating the at least one battery element and the printed circuit board and biasing the metallic foil coated on the surface of the partition wall toward the open shielding boxes, the printed circuit board overlying the battery element, wherein the printed circuit board and the battery are provided as an interconnected assembly prior to the assembly of the communication terminal.

13. A communication terminal as in claim 12 wherein the battery element is non-removably connected to the printed circuit board.

14. A communication terminal as in claim 12 wherein the battery element is separated from the printed circuit board by the partition wall over a substantial portion of its length.
