Abstract

The utility model discloses the structure of a portable micro electric charger, which is suitable for a rechargeable cell, wherein, a bottom box (2) whose inner part is stored with a charging circuit is provided with a power supply inserting foot (2) which can be stored in the box; when the charger is used, a release link (8) presses a spring lamination (6) to generate the displacement to make the inserting foot (2) jump out of the box (1) to connect and insert with the power supply under the action of a spring (3); a movable box (9) is sheathed with a bottom box (1) to make the movable box furled to the bottom box (1) to superpose with the bottom box (1) when the movable box (1) is not used; when the movable box (9) is used, the movable box (9) is a hollow cavity for containing the rechargeable cell. The utility model has the characteristics of good performance of charge, convenient storage and carryover, convenient use, etc.

Description

Portable micro electric charger

The utility model relates to dry battery charger.

Along with the fast development of electronics industry, electric equipment products such as midget receiver, electric shaver, remote controller and camera, communication BB machine are that vast house and traveller use day by day.For saving with conveniently, people generally bring into use rechargeable battery, bring market for thus various chargers.At present commercially available various chargers are fixed structure, and volume can not further dwindle and be difficult to satisfy people's portable requirement.

The purpose of this utility model is, designs a kind of portable minisize charger, is suitable for dry cell and uses, and it is good and volume is little, convenience easy to carry and use, reliable characteristics to have a charging effect.

The technical solution of the utility model is, it comprises the end box of built-in charging circuit device, this end box one side has the pin as power input, its design feature is, there is the uncovered moving box of indicator light and charging electrode to be socketed on the end box and and limits the position of moving box of the relative end of box by the outwardly extending lip of stretching limit and box both sides, the end in the moving box, one end of described pin is hinged with the axle that is contained in the end box, be equipped with between described axle and the pin and make pin stretch out the outer back-moving spring of end box, pin can rotate around the axis and pin groove on end box takes in the end box, inconsistent and make the shell fragment of its location with the pin hinged end when being equipped with in the box of the described end in pin income end box, the one end can be oppressed described shell fragment generation displacement and pin is resetted under spring action by the other end of the release link that end box opposite side stretches out.

Make below in conjunction with accompanying drawing and to further specify.

Description of drawings: Fig. 1 is the practical structures (moving box is opened) of the utility model band broken section, and Fig. 2 is the plan structure (moving box draws in) of device shown in Figure 1, and Fig. 3 is the charging circuit structure.In the drawings:

Box at the bottom of the 1-, the 2-pin, the 3-back-moving spring, the 4-outwardly extending lip, the 5-axle, the 6-shell fragment is stretched the limit in the 7-, the 8-release link, 9-moves box, 10-indicator light, 11-outwardly extending lip.

By accompanying drawing as can be known, the utility model has built-in charging circuit device, and (charging circuit can adopt prior art circuit shown in Figure 3, also can adopt the circuit of other prior art) end box (1), this end box (1) one side has the pin (2) as power input, and the physical dimension of pin (2) meets relative national standards, its design feature is, there is the uncovered moving box (9) of indicator lamp (10) and charging electrode to be socketed in end box (1) upward and to limit the position of moving box (9) box of the relative end (1) by the outwardly extending lip (4) (11) of stretching limit (7) and box both sides, the end in the moving box, one end of pin (2) is hinged with the axle (5) that is contained in the end box (1), be equipped with between axle (5) and the pin (2) and make pin (2) stretch out the outer back-moving spring (3) of end box (1), pin (2) can rotate and pin groove on end box (1) takes in the end box (1) (referring to Fig. 1 around axle (5), wherein the pin of solid line position (2) is the state in the income end box (1), dotted line position is for stretching out the operating position of end box (1)), mutually insulated between the pin, inconsistent and make the pin location shell fragment (6) of (keeping receiving the position to the end box (1)) with pin (2) hinged end when being equipped with in the box of the described end (1) in pin (2) income end box (1), the other end of the release link (8) that an end is stretched out by end box (1) opposite side can be oppressed shell fragment (6) generation displacement and pin (2) be resetted stretch out one by one outside the end box (1) under spring (3) acts on.

Design principle of the present utility model and the course of work are (referring to Fig. 1): when not using, and will Pin (2) rotates and takes in the end box (1) around axle (5), shell fragment (6) makes pin (2) keep state in this income box (1), to move the relative end box (1) of box (9) closes up, make box (9) overlap (box this moment (1) is in the box (9)) with end box (1), whole charger only has the size of end box (1); During use, pressing release link (8) makes pin (2) jump out end box under back-moving spring (3) effect, and will move the relative end box (1) of box (9) and pull open, then the cavity of rechargeable battery is held in uncovered moving box (9) inner chamber formation one, pack in rechargeable battery and the jack with pin (2) insertion mains power socket, can realize battery is charged. This charger adopts the charging circuit of capacitance decompression, and making it becomes possibility than the prior art charger product reduced volume of transformer pressure-reducing.

As known from the above, the utility model is a kind of Portable mini charger, and pin when not charging (2) and moving box (9) can draw in, adopt described charging circuit, has that charging effect is good, volume is little, a convenience easy to carry and use, reliable characteristics.

Embodiment: according to the charger of accompanying drawing and said structure, end box (1) and moving box (6) adopt plastics or its insulating material to make, pin (2) is for meeting two pin of national standard, moving box (9) inner chamber is for holding the cuboid cavity of No. 5 rechargeable battery two joints of standard, and the charging current of charging circuit is 50mA.Moving box (9) inner chamber also can be designed to hold the volume of No. 7 rechargeable batteries and other model rechargeable battery (be generally two joints, also can be a joint or a more piece).Charging electrode in the moving box (9) can adopt CONTACT WITH FRICTION to be connected with the counter electrode of end box (1).
