Description

BACKGROUND

1. Field of the Disclosure
The present disclosure relates to batteries and holding structures, particularly to a battery and a holding structure for holding the battery.
2. Description of Related Art
Portable electronic devices such as mobile phones and personal digital assistants (PDAs) are widely used. A battery having conductive connectors formed is generally installed in a receiving cavity of the portable electronic device. The conductive connector contact corresponding metallic elastic pins exposed inside the receiving cavity. Accordingly, the battery electrically connects the integrated circuit of the electronic device and provides electric energy for the electronic device. The battery is covered and secured by a cover.
However, a space between the battery and the sidewall of the receiving cavity is required for an assembly of the battery to the portable electronic device. The battery may move within the receiving cavity due to the space. Due to the movement of the battery, the electrical connection of the elastic pins and the conductive connector may be interrupted.
Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION OF THE EMBODIMENT

FIG.s 1 and 2 show an exemplary holding structure 100 for mobile phones, and other portable electronic devices, such as personal digital assistants (PDAs), digital cameras, etc. The holding structure 100 includes a housing 10 and a battery 20 detachably received in the housing 10.
The housing 10 defines a receiving cavity 12 to receive the battery 20. The receiving cavity 12 is enclosed by two sidewalls 14, a first end wall 16, and a second end wall 18. The first end wall 16 defines a locking groove 162 communicating the receiving cavity 12. The locking groove 162 is for latching with an end portion of the battery 20. The locking groove 162 has a stopping board 164 and an elastic member 166 (show in FIG. 3) therein. The elastic member 166 is resisted and deformed between the bottom of the locking groove 162 and the stopping board 164. The stopping board 164 can be moved within the locking groove 162 under the deformation of the elastic member 166. The second end wall 18 has a protrusion 182 protruding therefrom and located inside the receiving cavity 12. The protrusion 182 is engageable with the battery 20. A plurality of metallic elastic pins 19 are parallelly arrayed on the bottom and in a corner of the receiving cavity 12. Each elastic pins 19 includes a clamping section 192 extending perpendicularly to the bottom surface of the receiving cavity 12. The clamping section 192 has smaller width than the remainder of the elastic pins 19 to be secured with the battery 20.
The battery 20 includes a bottom surface 22, an end surface 24 and a top surface 26. The corner of the bottom surface 22 has a recess 222 defined therein. The recess 222 has a plurality of electrical strips 224 parallelly arranged therein. The electronic strips 224 are used to connect the elastic pins 192. Accordingly, the battery 20 is electrically conducted with the internal circuits of the housing 10. A protruding flange 226 extends above the recess 222. The protruding flange 226 is planar with the bottom surface 22 and defines a plurality of latching slots 2262 corresponding to elastic pins 19. Each latching slot 2262 aligns with an electrical strip 224 and is in a line with the electrical strip 224. The latching slot 2262 has the same width as the clamping section 192 and latches with the clamping section 192. The end surface 24 has a latching hole 242 defined to receive the protrusion 182 of the housing 10. The top surface 26 defines a step groove 262 opposite to the end surface 24, thus, the battery 20 forms an engaging end 264 corresponding to the step groove 262. The engaging end 264 can be received in the locking groove 162.
To assemble the battery 20 into the receiving cavity 12 of the housing 10, the engaging end 264 is received into the locking groove 162 and pressing against the stopping board 164. The stopping board 164 is pushed to abut against the inside of the locking groove 162 against the force of the elastic member 166. The other end of the battery 20 is assembled in the receiving cavity 12. The electronic strips 224 of the battery 20 resist the elastic pins 19, and the latching slots 2262 align above the clamping section 192 of the elastic pins 19. The battery 20 is then driven to slide toward the second end wall 18 by the return force of the elastic member 166. The clamping sections 192 are latched into the latching slots 2262. Meanwhile, the protrusion 182 of the second end wall 18 is received in the latching hole 242 of the battery 20. Therefore, the battery 20 is latched in the receiving cavity 12.
At this latched position, due to the latching of the clamping section 192 with the latching slots 2262, the elastic pins 19 cannot depart from the electronic strips 224 of the battery 20, which maintain a continuous power supplying of the battery 20 to the internal circuit of the housing 10.
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 disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
