Abstract
The utility model relates to a fuse resistor with M effect point. M effect points of a fuse resistor are brazed on wires through tinsel material in the prior art, center wires in the M effect points are circular, thus the fusing temperature, brazing temperature, and the speed of fusion erosion to wires of the M effect point are unable to be controlled within the required range in the use process, manufactures and users can not control the electric performances of the fuse resistor easily, and the safety of a circuit board is difficult to guarantee. The fuse resistor consists of a wire and an M effect point, wherein the wire in the range of 3mm on the center of the M effect point is a reducing flat wire, the thickness of the wire is 65%-95% of diameter, and the cross sections of the wires are kept unchangeable before and after diameter is changed, and the M effect point adopts copper tin alloy solder with 1%-10% copper content. Therefore, the fuse resistor has simple structure and reliable operation, can satisfy the requirements of users to electric performances, and effectively protects the safety of the circuit board.
Description
Technical field
The utility model relates to a kind of fusing resistor of the M of having effect point.
Background technology
At present, existing fusing resistor M effect point is to be soldered on the lead with the leypewter material, and M effect point place center conductor is a round conductor, like this, in use have the following disadvantages: the speed that lead is corroded in the melt temperature of M effect point alloy, welding temperature, the fusion of effect point can not effectively be controlled in the claimed range; Manufacturer, user are wayward to the electrical property of fuse; The safety of wiring board is difficult to be protected.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of simple in structure, reliable, and can satisfy the fusing resistor with M effect point of user to requirement on electric performance.
In order to achieve the above object, the technical solution adopted in the utility model is:
Fusing resistor with M effect point, its special character is: described fusing resistor is made of lead and M effect point; Lead in the described M effect 3mm of the dot center scope is the flat lead, and the flat conductor thickness is 65%～95% of a diameter of wire.
What described M effect point adopted is that copper content is the gun-metal solder of 1%-10%.
Reducing flat lead in the described M effect 3mm of the dot center scope, the front and back sectional area remains unchanged.
The utility model is as follows with respect to the advantage of prior art:
Adopting copper content is the material of the gun-metal solder of 1%-10% as M effect point, and the lead in the M effect 3mm of the dot center scope made reducing flat structure, make and the utlity model has: be simple in structure, reliable, and can satisfy the requirement of user to electrical property, relatively the melt temperature of fusing resistor has improved about 30 ℃ in the prior art, greatly reduces product in use to the strict demand of pin welding temperature, weld time; Aggravated the erosion of M effect point metal pair lead, made the fusing of fusing resistor quicker; The safety of simultaneously effective protection circuit plate.

Embodiment
Referring to accompanying drawing the utility model is further elaborated:
Fusing resistor with M effect point is made of lead 1 and M effect point 2; The lead that described M effect is put in the 2 center 3mm scopes is the flat lead, and the flat conductor thickness is 65%～95%. of lead 1 diameter
What described M effect point 2 adopted is that copper content is the gun-metal solder of 1%-10%.
Described M effect is put the reducing flat lead in the 2 center 3mm scopes, and the front and back sectional area remains unchanged.
The utility model can be used for not being higher than in the alternating current circuit of 80V direct current or 250V, is used for electric current restriction or isolated fault, has pin, can be welded on the circuit board, as the overload and the short circuit current protection of device and system; Wherein the short circuit current protective capability is used in the corresponding module of direct current at 3.5KA, uses as output or isolated fault protection.
When passing through fusing resistor in electric current is the rated current scope, fusing resistor is in thermal equilibrium state, and the fuse-link temperature remains unchanged substantially, and M effect point alloy material does not corrode fusing resistor human body conductor material, and circuit is in the safe operation state;
When electric current surpasses the conventional non fusing current of rated current, the caloric value of fusing resistor is a bit larger tham heat dissipation capacity, the fuse-link temperature rises, and in the certain hour scope, can reach heat balance, the fuse-link temperature remains unchanged substantially, but when surpassing outside the time range that requires of arranging not fuse, heat balance is broken, the fuse-link temperature rises, it is big that fusing resistor resistance becomes synchronously, the caloric value of fusing resistor is greater than heat dissipation capacity, and the fuse-link temperature constantly rises and reaches the initial melting temperature of M effect point alloy material, and the fusion of M effect point is also corroded the fusing resistor human body, when resistance becomes big with temperature, it is big that caloric value becomes synchronously, and M effect point alloy material melts also the disconnected fusing resistor human body lead of erosion rapidly, protective circuit safety;
When electric current surpasses the conventional fusing current of rated current, the caloric value of fusing resistor is greater than heat dissipation capacity, the fuse-link temperature constantly rises and reaches the initial melting temperature of M effect point alloy, the beginning fusion of M effect point is also corroded the fusing resistor human body, resistance becomes big with temperature, it is big that caloric value becomes synchronously, and M effect point melts and the disconnected fusing resistor of erosion, protective circuit safety;
When electric current surpassed the instantaneous blowout current of rated current, the caloric value of fusing resistor was much larger than heat dissipation capacity, and fusing resistor M effect point temperature raises rapidly and melts, the disconnected fusing resistor of erosion, protective circuit safety.
Because the utility model do not have housing, good heat dissipation, current density is big, and is in light weight so volume is little, and seldom drops during the thawing of M effect point, and more effectively the safety of protection circuit plate reaches the requirement of user to the fusing resistor electrical property.
