One can cascaded charge device
Technical field
The utility model relates to charging device field, particularly a kind of charging device that can cascade.
Background technology
In recent years, electronic product miscellaneous emerges in an endless stream, and each electronic product is equipped with respectively charging device.Taking baby antitheft label as example: hospital has baby to be born every day, but because baby's macroscopic features is similar, and its do not understand, ability to express, therefore, need to bring and identify and antitheft by high-tech means, baby antitheft label is born thus.Its working method is generally carries out gateway trigger alarm, needs the wrist strap of baby antitheft label to carry out connectivity detection simultaneously.The birth of considering baby is to factors such as the cycle of leaving hospital are shorter, and baby antitheft label is relatively applicable to adopting the solution of similar rechargeable battery.
It is that a rechargeable battery charges that traditional charger is generally a power supply adaptor, in the time that needs charge to multiple rechargeable batteries simultaneously, need the power supply adaptor of equal number, because baby antitheft label charger needs before use to arrange, registers and the operation such as charging, therefore generally all manage occasions such as being collected in nurse station concentratedly.With this understanding, because charging inlet is limited, cannot meet a large amount of charging demands, and charging device is also difficult for Collection and conservation, tends to cause nurse's workbench all in tumble, all can be more loaded down with trivial details in operation and storage.
Therefore, existing charging device cannot meet the charging demand under this type of special cases.
Utility model content
The utility model is for prior art above shortcomings, provides the one can cascaded charge device, and the utility model is achieved through the following technical solutions:
One can cascaded charge device, comprising:
Charging device main body;
Power supply adaptor interface, is arranged in charging device main body, in order to connect a power supply adaptor;
Charging inlet, is arranged on the end face of charging device main body, is electrically connected, in order to connect by charging device with power supply adaptor interface;
At least two subtending ports, are arranged in charging device main body, are electrically connected, respectively in order to connect the subtending port that another can cascaded charge device with power supply adaptor interface;
Wherein, under cascade state, some can connection successively by subtending port by cascaded charge device, wherein one can cascaded charge device power supply adaptor interface connect a power supply adaptor.
Preferably, charging inlet comprises:
Link slot, in order to place by charging device;
In link slot, be provided with charging contact, charged by charging device in order to connect.
Preferably, at least two subtending ports comprise respectively cascade contact, and under cascade state, some cascade contacts that can cascaded charge device interconnect.
Preferably, at least two subtending ports also comprise a tang and a recess, and cascade contact is separately positioned in tang and recess;
Under cascade state, between every all right one way or the other cascaded charge device, be connected by tang and recess, in order to increase the fastness of cascade.
Preferably, also comprise a charging indicator light, be arranged in charging device main body.
Preferably, charging inlet is electrically connected power supply adaptor interface by a power management chip.
The utility model, by subtending port is set, makes to need only one of them between multiple charging devices and connects a power supply adaptor, can complete the object that multiple rechargeable batteries are charged, and meanwhile, the utility model is simple in structure, with low cost, is suitable for promoting.

Embodiment
Below with reference to accompanying drawing of the present utility model; technical scheme in the utility model embodiment is carried out to clear, complete description and discussion; obviously; as described herein is only a part of example of the present utility model; it is not whole examples; based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work, belongs to protection range of the present utility model.
For the ease of the understanding to the utility model embodiment, be further explained as an example of specific embodiment example below in conjunction with accompanying drawing, and each embodiment does not form the restriction to the utility model embodiment.
Please refer to Fig. 1 to Fig. 4, the one that the present embodiment provides can cascaded charge device, comprising: charging device main body 1, power supply adaptor interface 5, charging inlet 2, at least two subtending ports 3.
Power supply adaptor interface 5 is arranged on a side of charging device main body 1, is used for connecting a power supply adaptor 8, thereby obtains electric energy.Charging inlet 2 comprises the charging contact 71 of link slot 6 and the portion that sets within it, and charging inlet 2 is positioned on the end face of charging device main body 1, and under charged state, rechargeable battery 9 is placed in link slot 6, is electrically connected with charging contact 7.
In the present embodiment, the quantity of subtending port 3 is two, is separately positioned on two corresponding sides of charging device main body 1, is provided with cascade contact 72 in subtending port 3.As shown in Figure 5, under cascade state, the subtending port 3 of multiple charging devices is connected respectively successively, and cascade contact 72 wherein also interconnects respectively, realizes multiple charging devices and uses a power supply adaptor 8 to charge.Power supply adaptor 8 can be connected on the power supply adaptor interface 5 of any charging device wherein.
Preferably, it is that 31, one subtending ports of tang are recess 32 that a subtending port can be set, and under cascade state, the tang 31 of a charging device is connected with the recess 32 of another charging device, can increase the fastness of connection.But the present embodiment not quantity to subtending port and position limits, it can be also that three above subtending ports are realized mode tree-shaped, starwise disposition that multiple charging devices can adopt the yi word pattern spread configuration of the present embodiment, and technical staff can configure arbitrarily according to actual conditions.
Similar to existing charging device, between charging inlet 2 and power supply adaptor interface 5, power management chip 4 can be set and carry out over-charge protective etc., ensure the safety of charging process.Meanwhile, charging indicator light can be set in charging device main body and show charged state.The utility model does not limit at this.
The above; it is only preferably embodiment of the utility model; but protection range of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claim.
