Abstract
The invention discloses a circuit device, and particularly provides a high-current fuse protector applied to projects. The fuse protector comprises a fuse wire and an outer shell, wherein thick connectors are arranged at the two ends of the fuse wire, the middle portion of the fuse wire is a thin fusing part, the thin fusing part is sleeved with the outer shell, and the space between the thin fusing part and the outer shell is filled with quartz sand. According to the fuse protector, since the space between the thin fusing part and the outer shell is filled with the quartz sand, under normal conditions, when a current passes through the fuse wire, the thin fusing part can emit a large amount of heat due to a small sectional area and high resistance, and the emitted heat can be dissipated through the quartz sand; when the current passing through the fuse wire is high, the quartz sand cannot dissipate the heat in time, the thin fusing part is broken through fusing, as a result, a high current fusing function is achieved, and the safety of other components and parts of a circuit is guaranteed.
Description
Technical field
The present invention relates to circuit elements device, particularly a kind of large current fuse being applied in engineering.
Background technology
Fuse is a kind of electronic device of generally using, the similar fuse of principle.At blowout current, require can directly adopt easy vertical bar type alloy to make in little, but blowout current require large in, common tactic pattern can not satisfy the demands.
Summary of the invention
Technical problem to be solved by this invention is: a kind of large current fuse being applied in engineering is provided.
The present invention solves technical scheme that its technical problem adopts: fuse, comprise fusible link and shell, and described fusible link two ends are set to thick joint, and middle part is set to the portion that carefully fuses, and described outer cover suit is in thin fusing portion; Between this thin fusing portion and shell, be filled with quartz sand.
For easily manufactured, the described thin fusing portion side's of being bar shaped.
For preventing thick joint fusing, improve radiating effect, on described thick joint, be provided with heat radiation groove.
For adapting to the fusing environment of large electric current, described fusible link adopts pure copper material to make.
For strengthening the resistance to elevated temperatures of fuse, described shell adopts ceramic material.
The invention has the beneficial effects as follows: fuse of the present invention, owing to being filled with quartz sand between thin fusing portion and shell, under normal circumstances, fusible link passes through electric current, carefully fusing portion is because sectional area is less, and resistance is larger, generates heat more, the heat distributing dispels the heat by quartz sand, when the electric current that passes through when fusible link is larger, quartz sand heat radiation is too late, carefully fusing portion fusing, thereby realize large current fusing function, guarantee the safety of other components and parts of circuit; Due to the described thin fusing portion side's of being bar shaped, manufacturing process is simple, and sectional area easily controls, thereby determines the blowout current of fuse, quite accurate; Owing to being provided with heat radiation groove on described thick joint, improved radiating effect, prevented thick joint fusing; Because described fusible link adopts pure copper material, make, can adapt to the fusing environment of large electric current; Because described shell adopts ceramic material, strengthened the resistance to elevated temperatures of fuse.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is along the generalized section of A-A in Fig. 1;
In figure, 1-thick joint, 2-shell, 3-quartz sand, 4-fusing portion carefully.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described, but protection scope of the present invention is not limited to the following stated.
As shown in Figure 1 and Figure 2, fuse of the present invention, comprises fusible link and shell 2, and described fusible link two ends are set to thick joint 1, and middle part is set to the portion that carefully fuses 4, and described shell 2 is sleeved in thin fusing portion 4; Between this thin fusing portion 4 and shell 2, be filled with quartz sand 3.Fuse of the present invention, owing to being filled with quartz sand 3 between thin fusing portion 4 and shell 2, under normal circumstances, fusible link is by electric current, and carefully fusing portion 4 is because sectional area is less, and resistance is larger, generate heat more, the heat distributing dispels the heat by quartz sand 3, when the electric current that passes through when fusible link is larger, reaches the blowout current of fuse, quartz sand heat radiation is too late, carefully fusing portion 4 fusing, thus realize large current fusing function, guarantee the safety of other components and parts of circuit.
Obvious thin fusing portion 4 can be cylindrical or other shapes, but its manufacturing process is comparatively complicated, sectional area is wayward, as preferred mode, is therefore that described thin fusing portion 4 is square bar shaped.Due to 4 sides of the being bar shaped of described thin fusing portion, manufacturing process is simple, and sectional area easily controls, thereby determines the blowout current of fuse, quite accurate.
User uses fusible link in when fusing, requires 4 fusing of thin fusing portion as far as possible, as preferred mode, is to be therefore provided with heat radiation groove on described thick joint 1, expands the contact area of thick joint 1 and air, has improved radiating effect, has prevented thick joint 1 fusing.
Described fusible link adopts pure copper material to make.Because described fusible link adopts pure copper material, make, can adapt to the fusing environment of large electric current.
Described shell 2 adopts ceramic material.Because described shell adopts ceramic material, strengthened the resistance to elevated temperatures of fuse, and ceramic seal has also stoped extraneous high energy particle to affect the fusing environment of thin fusing portion 4.
