Abstract

A battery holder assembly including a holder, positive and negative terminals secured to and extending out the holder, and a battery accommodated by the holder. The battery holder assembly is to be directly plugged into a printed circuit board. The battery is inserted into the holder along a direction substantially parallel to electrode surfaces thereof. The two terminals each have a respective terminal portion extending substantially parallel to the electrode surfaces of the battery so that the battery holder assembly occupies only a small space of the printed circuit board.

Claims

1. A battery holder assembly for plugging into an electronic device comprising:

a substantially rectangular holder having a first pair of walls, a second pair of walls smaller than the first pair of walls, a closed bottom and a battery-receiving portion opening at a top end thereof, a first and a second access openings being defined in the first pair of walls, respectively;

a first terminal extending through and secured to the bottom of the holder, the first terminal extending in a direction substantially parallel to the first pair of walls and being exposed to the first access opening, the first terminal being displaceable outward and inward via the first access opening; and

a second terminal extending through and secured to the bottom, the second terminal being spaced from the first terminal a predetermined distance and extending in said direction substantially parallel to the first pair of walls, the second terminal being located substantially below the second access opening.

2. The battery holder assembly as claimed in claim 1, wherein the bottom of the holder has two slits respectively proximate the first pair of walls for the first and second terminals to be anchored therein.

3. The battery holder assembly as claimed in claim 1, wherein each terminal has a terminal portion extending out of the bottom of the holder in a direction substantially parallel to the first pair of walls of the holder.

4. The battery holder assembly as claimed in claim 1, wherein the first terminal comprises a curved portion for electrically contacting the battery.

5. The battery holder assembly as claimed in claim 1, wherein the first terminal forms a convex curved portion at an end thereof facing the second terminal for urging a battery received in the battery-receiving portion against the second terminal.

6. The battery holder assembly as claimed in claim 1, wherein one of the first pair of walls adjacent to the first terminal includes a protrusion for preventing mis-orientation of the battery with respect to the holder.

7. The battery holder assembly as claimed in claim 1, wherein a stop laterally extends from the top end of the holder into the battery-receiving portion to prevent the battery from vertically sliding out of the battery-receiving portion.

8. A battery holder for receiving a battery therein and for use with an electronic device comprising:

a pair of walls opposite to each other defining a battery-receiving portion therein;

a first terminal extending along and adjacent to one of said walls;

a second terminal extending along and adjacent to the other of said walls;

wherein

said first terminal includes a curved portion for urging said battery against said second terminal, and wherein the wall adjacent to the second terminal includes a stop laterally extending from a top portion thereof so as to prevent the battery from sliding out of the battery-receiving portion after the battery has been fully installed into the holder.

9. The battery holder as claimed in claim 8, wherein the wall adjacent to the first terminal includes at least one protrusion for preventing mis-orientation of the battery with regard to the holder.

10. The battery holder as claimed in claim 8, wherein the wall adjacent the first terminal defines an access opening beside said first terminal for allowing outward and inward deflection of the first terminal.
