Abstract
The utility model relates to a charger, which comprises a charging circuit of which the input is connected to a power supply, wherein, the output of the charging circuit is connected with a ready-to-charge battery. The utility model is characterized in that a coupled switch which is composed of contacts (2) and a metal conductor is arranged between the charging circuit and a power input; the contacts (2) are positioned on an upper cover (1), connection triggering metallic conductors which are matched with the contact (2) is positioned on a body (8), and the connection triggering metallic conductors are respectively connected with the power input and the charging circuit. The utility model has the advantages of simple structure, convenient operation and high safety.
Description
Technical field:
The utility model is relevant with the household small-size charger.
Background technology:
The charging circuit of existing household small-size charger directly links to each other with the power supply input, plugs in, and charging circuit is just connected, and has very big potential safety hazard during use.
The content of utility model:
The purpose of this utility model provides charger a kind of simple in structure, easy to use, safe.
The utility model is achieved in that
This reality and use the New-type charge device, the input of charging circuit connects power supply, the output reception rechargable battery of charging circuit, it is characterized in that having between the input of charging circuit and power supply the linked switch of contact (2) and metallic conductor composition, contact (2) is positioned at loam cake (1), be connected metallic conductor with the triggering of contact (2) cooperation and be positioned at main body (8), be connected with charging circuit with the power supply input respectively.
Triggering connection metallic conductor is divided into corresponding two groups (9,10) and is connected with charging circuit with the power supply input respectively with (11,12), metallic conductor (9,11) is positioned on the insulation board (4), insulation board (4) porose be connected on the main body (8) lead (6) movingly, back-moving spring (5) is arranged on the lead (6).
Metallic conductor (10,12) is positioned on the mobile post (13,14), mobile post be positioned on the main body (8) the hole movingly, mobile post has back-moving spring (15) on (13,14).
Through hole (3) and contact (2) are arranged movingly on the main body (8), insulation board (4) is positioned at below the through hole (3).
The utility model charger housing loam cake and main body are provided with the interlock mains switch, and getting in touch of charging circuit and power input can be blocked and connect to the opening and closing of loam cake, can effectively solve charger safety problem in use.Simple in structure, with low cost, easy to use.
Description of drawings:
Fig. 1 is a structure chart of the present utility model.
Fig. 2 removes to cover vertical view for Fig. 1's.
Fig. 3 is that the A of Fig. 1 is to view.
Fig. 4 is the A-A partial sectional view of Fig. 2.
Embodiment:
Loam cake 1 one ends and main body 8 are hinged.Loam cake 1 other end has two contacts 2 corresponding with two through holes 3 on the main body 8.Support plate 16 usefulness screws 7 are fixed on the main body 8.Fix on the support plate 16 on two parallel leads 6 and the insulation board 4 through hole movingly, insulation board 4 is positioned at below the through hole 3, is fixed with sheet metal 9,11 below it to be connected with power supply input, with sheet metal 10,12 correspondences.Back-moving spring 5 is arranged on the lead.Sheet metal 10,12 is fixed on an end of mobile post 13,14.Through hole on mobile post 13,14 and the support plate 16 movingly, its another termination has back-moving spring 15 greater than through hole on the mobile post 13,14.Sheet metal 10,12 is connected with charging circuit.
When loam cake 1 was closed, two plastics contacts 2 were depressed the insulation board 4 of linked switch by hole 3, and sheet metal 9 and 10,11 and 12 is connected, and the input power supply arrives charging circuit smoothly.Upper plastic cover 1 all covers all charged positions in the charger get up simultaneously, and the user can not touch charged position.
When opening loam cake 1, insulation board 4 moves on spring 5 effect lower edge leads 6 and is returned to original position, separates sheet metal 9,10 and 11,12 simultaneously, disconnects the input power supply, makes charging circuit not charged.Back-moving spring 15 closely contacts sheet metal 9,10,11,12.
