BACKGROUND
1. Technical Field
The present disclosure relates to a battery holder, particularly, to a battery holder used in a portable electronic device.
2. Description of Related Art
Portable electronic devices, such as mobile phones, include batteries installed therein to supply electric power. A conventional portable electronic device generally includes a main body and a battery cover. The main body defines a chamber for receiving the battery, and the cover is attached to the housing to lock the battery in the chamber. A number of hooks are formed on the battery and a number of latching holes is defined in the main body. The cover firmly attaches to the main body by engagement between the hooks and the latching holes.
However, it may be hard to detach the hooks from the latching holes, and the hooks may wear and tear after repeat use.
Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION
FIG. 1 shows an exemplary embodiment of a battery holder 100. The battery holder 100 is applied to a portable electronic device (not labeled), such as mobile phone, personal digital assistant (PDA) for example. The battery holder 100 includes a housing 10, a main body 20, and a latching member 40. The main body 20 may be one part of the portable electronic device
The housing 10 includes a main plate 11 and two side plates 12. A stepped engaging portion 13 is formed on each side plate 12 adjacent to the main plate 11 for engaging with the main body 20.
The main body 20 defines a chamber 27 for receiving a battery 200 (shown in FIG. 4). A first sidewall 25, an end wall 24, and a second sidewall 26 surround the battery chamber 27. The sidewalls 25 and 26 are engaged with the engaging portion 13 of the housing 10.
Also referring to FIG. 2, a locking portion 22 is formed at one end of the first sidewall 25. The locking portion 22 defines a receiving groove 224 and a cutout 225. A hook 226 is formed between the receiving groove 224 and the cutout 225.
Also referring to FIG. 3, a latching portion 23 is positioned at one end of the second sidewall 26. The latching portion 23 defines a notch 234 and a slot 235. Two protrusions 232 and 233 extend over the notch 234. A space 236 is formed between the two protrusions 232 and 233. Referring to FIG. 1, an entrance 21 is formed between the locking portion 22 and the latching portion 23 communicating with the chamber 27. The entrance 21 allows the battery 200 to be inserted into the chamber 27.
A number of metal plates 244 is fixed on the end wall 24 for electrically connecting the battery 200 to a connector (not shown) in the portable electronic device. A projecting portion 242 is formed on the end wall 24 above the chamber 27 for locking the battery 200.
Referring to FIG. 4, the latching member 40 includes a main portion 41, a first end portion 43, and a second end portion 45. A block 411 extends from one side of the main portion 41. The main portion 41 may define a longitudinal through hole 413 to increase the elasticity of the main portion 41. In this exemplary embodiment, the latching member 40 is made of elastic material, such as rubber, to increase the elasticity of the main portion 41 and protect the battery 200 from damage.
The first end portion 43 includes a first bar 431, a second bar 432 and a gap 433 between the two bars 431 and 432. A shaft 435 is positioned at one end of the second bar 432, perpendicular to the second bar 432. The first bar 431 and the shaft 435 respectively engage in the slot 235 and the notch 234 of the latching portion 23.
The second end portion 45 includes a first tab 451, a second tab 452 and an retaining groove 453 between the two tabs 451 and 452. The first tab 451 and the second tab 452 respectively engage with the receiving groove 224 and the cutout 225 of the locking portion 22. The hook 226 extends through the retaining groove 453.
FIG. 5 shows the housing 10 and the latching member 40 attached to the main body 20. To attach the latching member 40 to the main body 20, the first bar 431 is engaged in the slot 235 of the latching portion 23. The second bar 432 is partially received in the space 236 between the two protrusions 232 and 233. The shaft 435 is rotatably received in the notch 234. Thus, the latching member 40 is rotatable relative to the shaft 435.
Also referring to FIGS. 6-7, while the latching member 40 is rotated up, the battery 200 is inserted into the chamber 27 through the entrance 21. The latching member 40 is then rotated down, and the second end portion 45 is pressed down. The hook 226 locks the second end portion 45, while the two tabs 451 and 452 are respectively engaged in the receiving groove 224 and the cutout 225. The block 411 abuts the battery 200 and pushes the battery 200 to firmly contact with the metal plates 244.
It is to be understood that even though numerous characteristics and advantages of the present embodiments have been set forth in the foregoing description, together with details of structures and functions of various embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the present invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
