A kind of Combined resistance box structure.
The technical solution adopted by the present invention is that:
A kind of Combined resistance box structure, including multiple resistance units, each resistance unit include a hollow ceramic rod,
The both ends of ceramic rod are respectively installed with a terminal plate, and the ceramic rod outer rim uniform intervals between two terminal plates are wound with resistance wire,
It is characterized by: multiple resistance units are vertically installed at respectively in a pedestal, and it is in sequential series between adjacent two resistance unit, it is located at
One terminal plate of outermost two resistance unit is connect with external circuit respectively.
Moreover, two terminal plate arranged in dislocation of the resistance unit, backwards to setting.
Moreover, be symmetrically mounted in pedestal per two adjacent resistance units, it is conductive using one between two ipsilateral terminal plates
The connection sheet that material is produced mutually is installed.
Moreover, uniform intervals produce multiple circular convex blocks in the upper surface of the pedestal, the outer diameter of each convex block with
The internal diameter of the ceramic rod inner edge of resistance unit is adapted, and ceramic rod is sleeved on the outside of convex block in the mounted state.
Moreover, a circle boss, the pedestal outer rim outer sheath above the boss are produced in the outer rim lower end of the pedestal outward
Equipped with a shell.
The advantages and positive effects of the present invention are:
In the present invention, pedestal is cooperated to form a new resistance box structure by resistance unit, and then realize and be directed to different resistances
It is worth the assembly of desired resistance box, first, the circle number tune of resistance wire winding can be passed through using the structure of ceramic rod winding resistance wire
The resistance value of whole single resistance unit can be realized second, the resistance unit of respective numbers and resistance box are embedded in cooperation to electricity
The resistance value requirement of case is hindered, simple installation is low in cost, and it is easy to disassemble, it is adaptable；
In the present invention, the terminal plate of each resistance unit is symmetrically installed backwards to being arranged per adjacent two resistance unit, be in order to
Convenient for the series connection and installation of resistance unit；The ceramic rod for the convex block cooperation resistance unit produced in pedestal is fixed, dismounting letter
Just, it can quickly assemble；The structure of pedestal and shell activity installation, then be to operate for the ease of staff, in series electrical
Shell can be removed when hindering unit, then by outer cover suit in chassis outer side after the completion of connecting, improve the safety of resistance box.
