Abstract
An over-current protector used with a power line is provided, which is characterized in that the over-current protector comprises a power line, a fuse and an insulating layer, wherein the fuse is connected in series with the power line; the junction of the fuse and the power line are coated with the insulating layer; the fuse has a pin at each of the two ends; the fusing body of the fuse is encapsulated in a ceramic tube; and the insulating layer has two or more layers. In the utility model, the fuse is directly connected in series with the power line, followed by injection molding for more than twice, so that the over-current protector has advantages of waterproofing property, simple structure, easy operation and low cost.
Description
Technical field
The utility model relates to a kind of injection moulding formula overcurrent protective device that is located on the power line, belongs to the improvement of overcurrent protective device.
Background technology
Present overcurrent protective device is a kind of to be that fuse is located in plug or the joint; because plug or joint kind are a lot; overcurrent protective device is set will multiple plug of specialized designs or joint; increased cost; another kind is that box of placing wiring board of design places on the power line, and cost is higher, and above-mentioned overcurrent protective device is as considering waterproof problem; structure more complicated often then, inconvenient operation.
Summary of the invention
The utility model has overcome shortcoming in the prior art; a kind of injection moulding formula overcurrent protective device that is located on the power line is provided, and fuse directly is serially connected on the power line, has passed through twice above injection mo(u)lding; both waterproof, simple in structure again, easy to operate, cost is low.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions: the utility model is made up of power line, fuse, insulating barrier, and fuse is serially connected in the power line, and the junction of fuse and power line is surrounded by insulating barrier.
Described fuse two ends have a pin respectively.
Described blown fuse body is encapsulated in the earthenware.
Described insulating barrier have two-layer more than.
The utility model overcurrent protective device compared with prior art has following beneficial effect:
1. because through twice above injection mo(u)lding, water resistance is good.
2. because fuse directly is serially connected on the power line, so simple in structure, easy to operate, cost is low.
Description of drawings
Fig. 1 is a longitudinal sectional drawing of the present utility model;
Fig. 2 is the longitudinal sectional drawing of fuse.
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As shown in Figure 1, the utility model is by power line 1, fuse 2, inner insulating layer 3, external insulation layer 4 is formed, wherein fuse 2 as shown in Figure 2, it is by pin 2.1, fuse-link 2.2, earthenware 2.3 is formed, from the centre of power line 1 its outer insulation is peelled off half with pocket knife, expose two strands, cut off a strand, and the inner insulating layer of its end peelled off respectively with the pin 2.1 at fuse 2 two ends be connected, the injection molded inner insulating layer 3 of die cavity is put in this junction, inner insulating layer 3 is put into the injection molded external insulation layer 4 of die cavity, required plug and joint in the difference injection moulding of the two ends of power line 1.
Claims (4)
