Abstract
The utility model discloses a high temperature protection wound -rotor type resistance overflows, including the plug, resistance wire, contact pin, its characterized in that cylindrical plug is chooseed for use to the plug, the plug both ends are provided with the contact pin respectively, be provided with the fuse on the plug, it forms the resistance type body evenly to twine the resistance wire on the periphery of plug, fuse one end is welded in the contact pin, the other end weld in the one end of the resistance type body, the other end of the resistance type body welds in another contact pin, the skin of the resistance type body scribbles epoxy resin coating, compared with the prior art, the utility model, reduced the volume of resistance greatly, the improvement of this structure, control fusing temperature that not only can be accurate, but also have that manufacturing process is simple, reasonable in design, small.
Description
Technical field
This utility model is related to electronic technology field, specifically a kind of excessively stream high temperature protection Wound-rotor type resistance.
Background technology
Wound-rotor type resistance in use, if the Wound-rotor type resistance continuous firing under low current working condition always,
Resistance temperature is rising always, finally results in resistance position other electronic components of periphery or device housings scald at high temperature
Deformation even scaling loss is bad, wherein described low current working condition refers to that electronic component operationally exceedes rated current and does not surpass
Cross a kind of state of blowout current.
Utility model content
The purpose of this utility model be in order to solve prior art in defect, there is provided a kind of excessively stream high temperature protection Wound-rotor type electricity
Hinder to solve the above problems.
To achieve these goals, the technical solution of the utility model is as follows：A kind of excessively stream high temperature protection Wound-rotor type resistance,
Including plug, resistance wire, contact pin, it is characterised in that the plug selects cylindrical mandrel, the plug two ends to be respectively arranged with
Contact pin, is provided with fuse on the plug, the outer uniform winding resistance wire of placing of the plug forms resistor-type body, the fuse
One end is welded in contact pin, and the other end is welded in one end of the resistor-type body, and the other end of the resistor-type body is welded in another
Contact pin, the outer layer of the resistor-type body scribbles epoxy coating.
Further improve, digging on the plug has the groove for placing fuse.
Further improve, the fuse uniform winding is in plug side.
This utility model compared with prior art, when resistance works long hours in low current working condition, resistive surface
Temperature be slowly increased, so as to the electronic component and its shell that avoid resistance periphery occur casing deformation or to cause the phenomenons such as fire
；And using directly on resistor-type body epoxy coating is coated replacing shell, the volume of resistance is substantially reduced, the knot
The improvement of structure, can not only accurately control fusing-off temperature, but also with manufacturing process is simple, reasonable in design, small volume.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Wherein, 01- plugs, 02- contact pins, 03- resistance wires, 04- fuses.
Specific embodiment
To make to have a better understanding and awareness architectural feature of the present utility model and the effect reached, to compared with
Good embodiment and accompanying drawing coordinates detailed description, is described as follows：
As shown in figure 1, a kind of excessively stream high temperature protection Wound-rotor type resistance that the present embodiment is provided, including plug 01, resistance wire
03, contact pin 02, it is characterised in that the plug 01 selects cylindrical mandrel, the two ends of the plug 01 to be respectively arranged with contact pin 02,
Fuse 04 is provided with the plug 03, the outer uniform winding resistance wire 03 of placing of the plug 01 forms resistor-type body, described
The one end of fuse 04 is welded in contact pin 02, and the other end is welded in one end of the resistor-type body, the other end weldering of the resistor-type body
Another contact pin is connected to, the outer layer of the resistor-type body scribbles epoxy coating.
In embodiment, for arranging for fuse can select the groove that placement fuse is reserved with plug, can select
By fuse uniform winding on plug, when resistance works long hours in low current working condition, the temperature of resistive surface is slow
Increase, when the temperature of resistance wire reaches fuse failure point, the contact pin that resistance wire is connected with the external world disconnects, and is prevented effectively from temperature rapid
Increase causes exception, so as to the electronic component scaling loss and its shell that avoid resistance periphery occur fusion crust, burn shell, casing deformation
Or cause the phenomenons such as fire；And using directly on resistor-type body coating epoxy coating replacing shell, it is also possible to rise
To cooling effect, while also significantly reducing the volume of resistance.
Ultimate principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Simply principle of the present utility model, this utility model also has respectively on the premise of without departing from this utility model spirit and scope
Changes and improvements are planted, these changes and improvements are both fallen within the range of claimed this utility model.This utility model is required
Protection domain defined by appending claims and its equivalent.
