1. Technical Field
The present disclosure relates to a battery holder.
2. Description of Related Art
In many computer systems, button batteries are commonly used to power complementary metal oxide semiconductor (CMOS) chips on motherboards. However, sometimes, a button battery may be loosened, and as a result, the CMOS chip will stop working, which is undesirable.
Many aspects of the present embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments. Moreover, in the drawings, all the views are schematic, and like reference numerals designate corresponding parts throughout the several views.
The disclosure, including the accompanying drawings, is illustrated by way of example and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to
The base 20 includes a substantially circular bottom wall 22 and a first sidewall 24 extending in a substantially perpendicular manner from the circumference of the bottom wall 22. A first receiving space 26 is bounded by the bottom wall 22 and the first sidewall 24. A rectangular slot 220 is defined in the bottom wall 22. A first conductive piece 222 is mounted to the bottom wall 22 in the receiving space 25 at a first end of the slot 220, and slants up toward the second end of the slot 220 opposite to the first end in the first receiving space 26. Two pins 224 (anode pin 224 and cathode pin 224) extend in a substantially perpendicular manner from the outer surface of the bottom wall 22 opposite to the receiving space 26. The cathode pin 224 is located at the first end of the slot 220 and is electrically connected to the first conductive piece 222 in the bottom wall 22. The other pin 224 is located adjacent to the second end of the slot 220. Two diametrically opposing recesses 240 are defined in an outer surface of the first sidewall 24. A latching hole 242 through the inner surface of the first sidewall 24 is defined in each recess 240. A second conductive piece 28 is mounted in one of the recesses 240, and extends through the bottom wall 22 to connect to the other pin 224. A through hole 280 is defined in the second conductive piece 28, aligning with the latching hole 242. An extension piece 282 extends in a substantially perpendicular manner from the second conductive piece 28 to contact the top side of the latching hole 242.
The cover 30 includes a circular top wall 32 defining an opening 33 in the center and a second sidewall 34 extending in a substantially perpendicular manner from the circumference of the top wall 32. A second receiving space 36 is bounded by the top wall 32 and by the second sidewall 34. A circular third conductive piece 320 is mounted on the inner surface of the top wall 32. Two inwardly-acting opposing latches 340 extend from the second sidewall 34, away from the top wall 32. Each latch 340 includes an elastic extension portion 342 extending from the second sidewall 34, and a hook 344 extending from the distal end of the extension portion 342 toward the other latch 34. A fourth conductive piece 38 forms the outer face of the inner surface of one of the hooks 344, and the fourth conductive piece 38 extends through the corresponding extension portion 342 and the second sidewall 34, to be connected to the third conductive piece 320.
