Abstract
The utility model relates to a fusing display replaceable charger, which comprises a charging circuit board which is arranged inside an upper shell and a lower shell, wherein the charging circuit board is connected with a DC charging output wire, and is characterized in that a DC loop of the DC charging output wire is provided with a fuse which is blown out when the DC loop is in short circuit ora charging battery is in reverse connection, wherein the fuse is arranged on the edge of the charging circuit board, and a notch which is used for holding an elastic flap is arranged on the upper shell and/or the lower shell to correspond to the fuse. When the fuse is blown out, the fuse can be replaced only by opening the elastic flap. The fusing display replaceable charger can prevent the situation that the charger is burned when the DC loop is in short circuit or the charging battery is in reverse connection, and has simple structure and convenient application.
Description
Technical field
The utility model relates to a kind of fusing and shows changeable charger.
Background technology
Existing charger, electric vehicle charger for example, charging current is bigger, and the charger interface type is more, and the user often with the both positive and negative polarity mistake of DC charging end, causes charger to burn.Also there is the situation that charger is burnt in the direct short-circuit of DC charging end.How avoiding burning whole charger when above-mentioned situation occurring, is the technical barrier that those skilled in the art will solve.
The utility model content
Technical problem to be solved in the utility model provides a kind of fusing that has fuse and be convenient to change after blown fuse and shows changeable charger.
For solving the problems of the technologies described above, the utility model provides a kind of fusing to show changeable charger, comprise: be located at the charging circuit board in upper shell and the lower house, be connected with the DC charging output line on the charging circuit board, be characterized in: be provided with the fuse that is used in the DC loop short circuit or fuses during with the rechargeable battery reversal connection in the DC loop of described DC charging output line place; Fuse is arranged on the edge of charging circuit board, and being provided with the fuse corresponding section on upper shell and/or lower house is used to be provided with the breach that elasticity is renovated.
Further, the end face of described upper shell and lower house is provided with radiating groove and the through hole of the LED of luminous indication when being used to be arranged on blown fuse.
The utlity model has positive effect: (1) fusing of the present utility model shows in the changeable charger and has fuse, is used in the DC loop short circuit or fuses during with the rechargeable battery reversal connection.And fuse is arranged on the edge of charging circuit board, being provided with the fuse corresponding section on upper shell and lower house is used to be provided with the breach that elasticity is renovated, after described blown fuse, as long as open that elasticity renovates is replaceable fuse, can avoid in the situation that the DC loop short circuit occurs or burn charger during with the rechargeable battery reversal connection, simple in structure, easy to use.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 shows the decomposition texture schematic diagram of changeable charger for the fusing of embodiment 1.
Embodiment
See Fig. 1-10, the fusing of present embodiment shows that changeable charger comprises: be located at the charging circuit board 3 in upper shell 1 and the lower house 2, be connected with the DC charging output line on the charging circuit board 3, it is characterized in that: be provided with the fuse 3-1 that is used in the DC loop short circuit or fuses during with the rechargeable battery reversal connection in the DC loop of described DC charging output line place; Fuse 3-1 is arranged on the edge of charging circuit board 3, and being provided with fuse 3-1 corresponding section on upper shell 1 and/or lower house 2 is used to be provided with elasticity and renovates 4 breach 1-1.After described fuse 3-1 fusing, as long as opening elasticity, to renovate 4 be replaceable fuse 3-1, can avoid in the situation that the DC loop short circuit occurs or burn charger during with the rechargeable battery reversal connection so the fusing of present embodiment shows changeable charger, and it is simple in structure, easy to use.
The through hole of the LED of luminous indication when the end face of described upper shell 1 and lower house 2 is provided with radiating groove and is used to be arranged on fuse 3-1 fusing.
Obviously, the foregoing description only is for the utility model example clearly is described, and is not to be qualification to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all execution modes.And these belong to conspicuous variation or the change that spirit of the present utility model extended out and still are among the protection range of the present utility model.
Claims (2)
1, a kind of fusing shows changeable charger, comprise: be located at the charging circuit board (3) in upper shell (1) and the lower house (2), charging circuit board is connected with the DC charging output line on (3), it is characterized in that: be provided with the fuse (3-1) that is used in the DC loop short circuit or fuses during with the rechargeable battery reversal connection in the DC loop of described DC charging output line place; Fuse (3-1) is arranged on the edge of charging circuit board (3), and being provided with fuse (3-1) corresponding section on upper shell (1) and/or lower house (2) is used to be provided with elasticity and renovates the breach of (4) (1-1).
2, fusing according to claim 1 shows changeable charger, it is characterized in that: the through hole of the LED of luminous indication when the end face of described upper shell (1) and lower house (2) is provided with radiating groove and is used to be arranged on fuse (3-1) fusing.
