Description
Technical field
The utility model relates to a kind of safety-type circuit plate.
Background technology
Circuit board is comparatively common a kind of electric elements, by soldering of electronic components on circuit board, can reduce the use of electric wire, being convenient to the later stage is that electronic equipment keeps in repair, but existing circuit board scarcely has safety means, when causing the short circuit of circuit board internal components, whole circuit board burns out thereupon, and the electronic component being welded on circuit board also damages thereupon, cause higher maintenance cost, in existing electronic equipment, its safety means that possess are arranged on position of source place mostly, cut off the electricity supply in the timing of electronic equipment internal voltage instability, but these safety means cannot protective circuit plate, therefore need a kind of circuit board that possesses safety means, to avoid circuit board damage.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of safety-type circuit plate, and this device is provided with fuse, in the time that the electric current that enters circuit board inside is greater than the load electric current of circuit board; automatically fusing; protective circuit plate, avoids circuit board overload to damage, and reduces user's loss.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of safety-type circuit plate, comprise circuit substrate, and be arranged on the wiring layer of circuit substrate upper surface, and cover the soldering-resistance layer of described wiring layer, also comprise the bus that connects described wiring layer, the side of described circuit substrate is provided with fuse, described fuse is connected with described bus, described fuse comprises box body, and be arranged on the cavity at box body middle part, one end of described cavity is provided with cathode-chip wiring, the other end arranges cathode wiring plate, described box body outer setting has a power supply terminal that connects described cathode-chip wiring, described cathode wiring plate is connected with described bus, between described cathode-chip wiring and cathode wiring plate, be connected with resistance wire.
As preferred technical scheme, described wiring layer comprises some wire silks, and connects the welding hole of this wire filaments, and described wire filaments connects bus.
As preferred technical scheme, described box body deviates from the side of described power supply terminal and has card division, is connected with the first screw between described card division and circuit substrate
As preferred technical scheme, on described power supply terminal, be provided with one and compress the screw that electric wire is used, described screw extends on that end face in power supply terminal and is provided with sheet rubber.
The beneficial effects of the utility model are: this device is provided with fuse, in the time that the electric current that enters circuit board inside is greater than the load electric current of circuit board, and fusing automatically, protective circuit plate, avoids circuit board overload to damage, and reduces user's loss.
