Description

The conducting terminal of the dual-purpose cradle of thickness battery and this cradle of application

Technical field

This is novel to relate to a kind of cradle, particularly relates to the charge cradle of operation of a kind of battery for PDA(Personal Digital Assistant).

Background technology

Known PDA(Personal Digital Assistant) or portable computer portable electronic devices such as (PC), because its volume is little, in light weight, become one of carry-on articles of many people, but want to continue for a long time to use personal digital assistant, whether its battery provides enough electric power then is main key to the issue, because the general electric weight of the incidental standard cell of personal digital assistant is limited can not satisfy user demand, therefore the user is except original standard cell, usually to buy a high-capacity battery again, to offer personal digital assistant than long service time.

As Fig. 1 and Fig. 2, because being the bodies 4 with personal digital assistant 100, the shape and size of standard cell 3 form one, therefore when standard cell 3 is assembled in the body 4 of personal digital assistant 100, the back side 41 of whole personal digital assistant 100 still can keep its flatness, so horizontal on the table the time, there is no the problem in any placement.

But as shown in Figure 3 and Figure 4, only just storing the different viewpoint of electric weight considers, the actual between the two difference of high-capacity battery 2 and standard cell 3 only is different on the thickness usually, because of the problem on considering actual assembled and using, high-capacity battery 2 not only has bigger thickness than standard cell 3, and the size on its plane also must increase.Main consideration main points are, when the body 4 of personal digital assistant 100 is assembled with high-capacity battery 2, high-capacity battery 2 will form a massif on the back side 41 of the body 4 of personal digital assistant 100, when the personal digital assistant 100 usefulness back sides 41 are flat on the desktop, the body 4 of personal digital assistant 100 promptly can because of high-capacity battery 2 formed massifs by jack-up, little and when not being positioned in shape center of whole personal digital assistant 100 as the massif area, the phenomenon that has the promptly easy oriented inclination of external force to turn over slightly takes place, very infirm on placing, for this reason, high-capacity battery 2 not only increases its thickness when design, and must strengthen the size on outward appearance plane simultaneously, make it except having a main part 22, also form the outward extending extension 23 of autonomous body 22 sides, after making that the high-capacity battery 2 and the body 4 of personal digital assistant 100 are assembled, main part 22 can have enough Area of bearing with the massif that extension 23 forms on the back side 41 of body 4, when its back side 41 of personal digital assistant 100 usefulness places on the desktop, thereby be unlikely to turn over the storing state that keeps stable to an inclination.So, to compare with standard cell 3, high-capacity battery 2 not only increases on thickness, and its face shaping is therefore also inequality.

Because above-mentioned standard cell 3 forms difform design with high-capacity battery 2 on function and actual assembled, feasible cradle in order to the operation of charging also must be adapted to standard cell 3 and high-capacity battery 2, but require the restriction of simplifying and cost of manufacture based on charging socket structure, can not on cradle, be provided with simultaneously respectively for the slot of standard cell 3 and high-capacity battery 2 chargings and the electric connector of correspondence, therefore make cradle must be designed to single slot, and can adapt to thickness and variform standard cell 3 and high-capacity battery 2.
