Description
Technical field
The utility model relates to power tool accessory technical field, refers in particular to a kind of batteries for electric tools bag.
Background technology
The equal power brick of current electric tool is generally made up of the shell and the some batteries be arranged in shell internal cavity that are provided with battery internal cavity, and battery is connected in series in internal cavity; Power brick carries out charging and discharging use at high voltage; Because general battery is lithium battery, during charging, ensure that the every part battery after connecting will at specific voltage, all need power up sub-protection circuit to prevent at present and often prop up voltage overtension when charging, when battery is more, protection circuit is more complicated, and cost is higher; When certain part battery failure problem, normal work and the discharge and recharge of whole battery pack can be affected, directly cause scrapping of power brick.
Utility model content
The utility model is the deficiency existed for current power tool battery bag, and provides a kind of batteries for electric tools bag overcome the above problems.
For achieving the above object, the utility model adopts following technical scheme:
A kind of batteries for electric tools bag, described power brick is made up of the shell and the some batteries be arranged in shell internal cavity being provided with battery internal cavity; The positive pole of described every part battery, negative pole connect cathode conductive film, cathode conductive film respectively, described cathode conductive film, cathode conductive film are connected to outside shell, and an end face of shell arranges that cathode conductive film, cathode conductive film just connect contact, negative connect contact arranging.
Preferably, describedly just connecting contact, negative to connect contact be blade contact.
Preferably, describedly just connecting contact, negative to connect contact be elastic clip blade contact.
The beneficial effects of the utility model are: batteries for electric tools bag of the present utility model, the positive pole of described every part battery, negative pole connect cathode conductive film, cathode conductive film respectively, described cathode conductive film, cathode conductive film are connected to outside shell, and an end face of shell arranges that cathode conductive film, cathode conductive film just connect contact, negative connect contact arranging; When charging, the connector of charging device and the side of power brick just connect contact, the negative contact that connects is connected, charging device arranges circuit makes the cell parallel in power brick connect, only simple transforming circuit need be set, just the consistency of the charging voltage of all batteries can be ensured, structure is simple, saves cost; In addition during certain part battery failure problem, normal work and the discharge and recharge of whole battery pack can not be affected, power brick can also continue use.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model power brick
Fig. 2 is an execution mode end face structure schematic diagram of the utility model power brick
Fig. 3 is another structural representation of the utility model power brick
Embodiment
Below in conjunction with accompanying drawing 1-3, the utility model is further elaborated:
A kind of batteries for electric tools bag, power brick is made up of the shell 1 and the some batteries 2 be arranged in shell 1 internal cavity 11 being provided with battery internal cavity 11; Shell 1 can be arranged to different shapes according to demand, as rectangular shape, ellipticity, triangle etc.; The positive pole 21 of every part battery 2, negative pole 22 connect cathode conductive film 3, cathode conductive film 4 respectively, and cathode conductive film 3, cathode conductive film 4 can be connected on the positive pole 21 of battery 2, negative pole 22 by the mode such as butt-joint, spot welding; Cathode conductive film 3, cathode conductive film 4 are connected to outside shell 1, and an end face of shell 1 arranges that cathode conductive film 3, cathode conductive film 4 just connect contact 5, negative connect contact 6 arranging; Those skilled in the art by just connecting contact 5, the negative contact 6 that connects for blade contact, can be embedded the end face (as shown in Figure 1, 2) at shell 1, arranging to strike the post carry out being connected with power brick by charger or electric tool; Just can also connect contact 5, the negative contact 6 that connects is elastic clip blade contact (as shown in Figure 3), as the contact in socket, arranging joint pin by charger or electric tool carries out being connected with power brick; In addition, the connection of shell 1 and battery 2 be those skilled in the art know the technological means known, do not do too much repeating at this.
Batteries for electric tools bag of the present utility model, the positive pole 21 of described every part battery 2, negative pole 22 connect cathode conductive film 3, cathode conductive film 4 respectively, described cathode conductive film 3, cathode conductive film 4 are connected to outside shell 1, and an end face of shell 1 arranges that cathode conductive film 3, cathode conductive film 4 just connect contact 5, negative connect contact 6 arranging; When charging, the connector of charging device and the side of power brick just connect contact 5, the negative contact 6 that connects is connected, charging device arranges circuit makes the battery 2 in power brick be connected in parallel, only simple transforming circuit need be set, just the consistency of the charging voltage of all batteries 2 can be ensured, structure is simple, saves cost; In addition certain part battery 2 break down problem time, normal work and the discharge and recharge of whole battery pack can not be affected, power brick can also continue use; When the work of electric discharge, electric tool arranges circuit makes the battery 2 in power brick be connected in series.
The above embodiment, just preferred embodiments of the present utility model, be not limit the utility model practical range, therefore all equivalences done according to structure, feature and the principle described in the utility model claim change or modify, and all should be included in the utility model patent claim.
