Description
[technical field]
The present invention relates to resistor technologies field, particularly relate to the resistor of a kind of anti-lightning and mistake short circuit type.
[background technology]
Current resistor, insulating body is wound around resistance wire, is carried out the size of controlling resistance by the length of resistance wire; But these resistance wires, what the diameter of resistance wire was less may be used for short-circuit protection, and when crossing short circuit, the resistance wire immediate current that diameter is less increases and melts and disconnect; But but can not play the effect of anti-lightning when resistance wire diameter is less, anti-lightning needs the resistance wire using diameter larger; By this, present resistor can not simultaneously for crossing short-circuit protection and anti-lightning.
[summary of the invention]
The object of the invention is to overcome current resistor can not simultaneously for crossing a kind of resistor that short circuit and the deficiency of protection against lightning strikes provide.
The present invention is achieved through the following technical solutions: the fusing resistor of a kind of anti-lightning and short circuit excessively, comprise an insulating body, the two ends of described insulating body are respectively provided with a metal cap, described insulating body is cylindrical-shaped structure, described insulating body is wound with resistance wire, the two ends of described resistance wire are connected with the metal cap at described insulating body two ends respectively, a metal cap external pin respectively at described insulating body two ends, the skin of described insulating body is also provided with one deck heat dissipating layer, and described resistance wire is wrapped in described heat dissipating layer; Described resistance wire is that ptc material is made.
Below above technical scheme is further elaborated:
Further, described insulating body is ceramic material.
Further, described metal cap is zinc-plated chapeau de fer.
Further, described pin is CP wire.
Beneficial effect of the present invention is: the resistor of one, this structure, and its resistance wire is that ptc material is made; The resistance wire that ptc material makes, when electric current increases instantaneously time, resistance wire generates heat, and its resistance also becomes large, and electric current will reduce thereupon; When electric current becomes very large instantaneously time, wire temperature will be very high, and now, the resistance wire that ptc material makes will be fused, and without explosive sound, no-spark during fusing; For the resistance wire that above-mentioned ptc material makes, when meeting thunderbolt voltage, electric current increases instantaneously, and resistance wire generates heat, and resistance also becomes large thereupon, and the electric current of haveing suffered circuit will diminish, and by this, circuit is protected when being struck by lightning; When having served as short circuit, the electric current in circuit becomes suitable large instantaneously, and now, the resistance wire that ptc material makes will fuse, and occurs open circuit, and can not produce explosive sound and spark.By this, the electronic devices and components of whole circuit also can not be burned and be protected; Two, described pin is CP wire, and uses tin-coated copper as compared with pin in prior art, has saved cost with CP wire as pin.
[accompanying drawing explanation]
Fig. 1 is overall structure schematic diagram of the present invention.
Reference numeral: 1, insulating body; 2, metal cap; 3, resistance wire; 4, pin; 5, heat dissipating layer.
[embodiment]
Below in conjunction with the drawings and the specific embodiments, the present invention is described further:
With reference to shown in Fig. 1, the fixing fusing resistor of this embodiment, it comprises an insulating body 1, and the two ends of described insulating body 1 are respectively provided with a metal cap 2, and described metal cap 2 is zinc-plated chapeau de fer; Described insulating body 1 is cylindrical-shaped structure, and insulating body 1 is ceramic material; Described insulating body 1 is wound with resistance wire 3, and the two ends of described resistance wire 3 are connected with the metal cap 2 at described insulating body 1 two ends respectively, a metal cap 2 external pin 4 respectively at described insulating body 1 two ends, and described pin 4 is CP wire; The skin of described insulating body 1 is also provided with one deck heat dissipating layer 5, and described resistance wire 3 is wrapped in described heat dissipating layer 5; Described resistance wire 3 is made for ptc material.
The resistor of this structure, its resistance wire 3 is made for ptc material; The resistance wire 3 that ptc material makes, when electric current increases instantaneously time, resistance wire 3 generates heat, and its resistance also becomes large, and electric current will reduce thereupon; When electric current becomes very large instantaneously time, resistance wire 3 temperature will be very high, and now, the resistance wire 3 that ptc material makes will be fused, and without explosive sound, no-spark during fusing; For the resistance wire 3 that above-mentioned ptc material makes, when meeting thunderbolt voltage, electric current increases instantaneously, and resistance wire 3 generates heat, and resistance also becomes large thereupon, and the electric current of haveing suffered circuit will diminish, and by this, circuit is protected when being struck by lightning; When having served as short circuit, the electric current in circuit becomes suitable large instantaneously, and now, the resistance wire 3 that ptc material makes will fuse, and occurs open circuit, and without explosive sound, no-spark during fusing; By this, the electronic devices and components of whole circuit also can not be burned and be protected; In addition, described pin 4 is CP wire, and uses tin-coated copper as compared with pin 4 in prior art, has saved cost with CP wire as pin 4.
The announcement of book and instruction according to the above description, those skilled in the art in the invention can also carry out suitable change and amendment to above-mentioned execution mode.Therefore, the present invention is not limited to embodiment disclosed and described above, also should fall in the protection range of claim of the present invention modifications and changes more of the present invention.In addition, although employ some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the present invention.
