Abstract
The utility model discloses an anti-surge and anti-explosion winding resistor which comprises a core rod and two caps. Two ends of the core rod are respectively connected with the two caps. The anti-surge and anti-explosion winding resistor is characterized in that a resistance wire is wound on the core rod, one end of the resistance wire is connected with a cap through a current fuse, and the other end of the resistance wire is connected with the other cap; one end of a lead at one side is connected with one cap, one end of a lead at the other side is connected with the other cap, and the density of the resistance wire wound on the middle part of the core rod is higher than that of the resistance wire wound close to two ends of the core rod. The anti-surge and anti-explosion winding resistor has reasonable structure and anti-surge performance, is safe to use, and can be fused in short time so as to protect the circuit. A protective sleeve can prevent safety problem caused by combustion or explosion. In addition, one end of the resistance wire is connected with one cap through the current fuse, the safety problems caused by combustion or explosion due to an overheat situation caused by over-double overlarge current generated by surging or line fault can be effectively prevented.
Description
Technical field:
The utility model belongs to the electronic devices and components field, especially belongs to the explosion-proof wire wound resistor of a kind of antisurge.
Background technology:
The structure of existing a kind of anti-lightning surge wire wound resistor is: be wound with resistance wire on the plug, and the winding density of resistance wire on plug is even, the two ends of resistance wire join with a section lead respectively, at the flame retardant paint that is externally coated with of inner core and resistance wire.The main deficiency that the resistor of this structure exists is: when the electric current by resistor greater than the multiple of its rated current hour, for example, when the electric current by resistor is 2.5～3 times of its rated current, resistor can't in time fuse, the persistent fever phenomenon can appear in resistor, its surface temperature can surpass 600 ℃, brings potential safety hazard thus.
Summary of the invention:
The purpose of this utility model is to provide a kind of low cost of manufacture, technology is simple, easy to operate, high temperature resistant and the explosion-proof wire wound resistor of antisurge good anti-vibration.
The purpose of this utility model is to realize like this, the explosion-proof wire wound resistor of described antisurge, comprise plug and two caps, the two ends of this plug are connected with this cap respectively, its design feature is to be wound with resistance wire on the plug, one end of resistance wire is connected with a cap through the electric current fuse, and the other end of resistance wire is connected with another cap; One end of one side lead is connected with a cap, and an end of opposite side lead is connected with another cap, and the density that resistance wire twines at the plug middle part is higher than the winding density near the place, two ends.
The purpose of this utility model also can be achieved through the following technical solutions, the explosion-proof wire wound resistor of described antisurge, its characteristics for cap, plug and on the external packets of resistance wire be covered with flame-retardant layer.The explosion-proof wire wound resistor of described antisurge, its characteristics be the external packets cap that is covered with flame-retardant layer, plug and on resistance wire be sealed in the protection tube.
Advantage of the present utility model: compared with prior art, the utility model is rational in infrastructure, safe in utilization, and it promptly has the antisurge performance, and the effect of protective circuit is played in short time fusing.Protection tube can prevent burning or blast and cause safety problem.And an end of resistance wire is connected with a cap through the electric current fuse; can prevent that surge from producing effectively or line fault produces surpass that super-high-current more than 2 times causes overheated and burning or blast take place and cause safety problem; thereby an excess current protective function is arranged; characteristics such as it is good to have security performance, and the scope of application is wider.
