Abstract
The utility model relates to a novel structural formula resistance, including zinc oxide ceramics linear resistance core, high pressure resistant, the small and stable performance lamp characteristics of oxide ceramic linear resistance prevent that the electric current is too big, burn out the circuit and cause the accident, the outside of zinc oxide ceramics linear resistance core is equipped with the shell, along the resistance hole has been seted up to zinc oxide ceramics linear resistance dabber core wire direction, the downthehole screw thread erection column of installing of resistance a plurality of screw post is installed to the outer circumference of shell. The utility model discloses novel structure is unique, and installation convenient to use through being provided with screw thread erection column and screw thread post, installs electronic circuit through the screw thread with resistance, be convenient for installation and dismantlement, repeatedly usable.
Description
Technical field
The utility model relates to technical field of electronic components, specifically refers to a kind of resistance, particularly relates to a kind of new structure formula resistance.
Background technology
The English name of resistance is resistance, is usually abbreviated as R, and it is a kind of fundamental property of conductor, relevant with the size of conductor, material, temperature.Ohm's law points out voltage, pass between electric current and resistance three is I=U/R, that is R=U/I.The base unit of resistance is ohm, represents with Greek alphabet " Ω ".Resistance is on the market divided into simple monodrome resistance and resistance-changing resistor, cannot meet modern society's diversified demand.Resistance of the prior art mainly comprises columned resistor main body, the resistance rod member be arranged in resistor main body, described resistance rod member is arranged in electronic circuit by the mode of welding, this welding manner structure is simple, but can not dismantle, if have to dismantle, whole electronic component around can be caused to damage.
Utility model content
The utility model, in order to overcome deficiency of the prior art, provides a kind of new structure formula resistance, is threaded connection and is convenient to installation and removal.
The utility model is achieved through the following technical solutions:
A kind of new structure formula resistance, comprise Zinc oxide ceramic linear resistor core, oxide ceramic linear resistance is high pressure resistant, volume is little and stable performance lamp feature, prevent electric current excessive, burn out circuit to cause the accident, the outside of described Zinc oxide ceramic linear resistor core is provided with shell, offers resistance hole along described Zinc oxide ceramic linear resistor core direction of axis line, in described resistance hole, screw thread erection column is installed, at the excircle of described shell, several threaded post is installed.
As optimal technical scheme of the present utility model, the quantity of described threaded post is four, is symmetrically distributed on shell.
As optimal technical scheme of the present utility model, described shell adopts carbon film material to make, and its thickness is 5mm-10mm.
As optimal technical scheme of the present utility model, described screw thread erection column and resistance hole interference fit are installed.
As optimal technical scheme of the present utility model, described threaded post is fixedly connected with shell.
Compared with prior art, the beneficial effects of the utility model are: the utility model novel structure is unique, easy to install, by being provided with screw thread erection column and threaded post, by screw thread resistance is installed in electronic circuit and goes, be convenient to installation and removal, reusable.
