Description

A kind of Combined resistance box structure
Technical field
The utility model belongs to electric appliance original part manufacturing field, is related to high-power resistance manufacture, especially a kind of Combined resistance Box structure.
Background technique
In Electric Appliance Cabinet, the large scale electrical power units such as transformer, resistance used is mostly powerful resistance box.
Existing resistance box is mostly nonstandard product, need to be made according to the requirement such as resistance value and model etc. of large scale electrical power unit It makes.For the production and manufacture of above-mentioned resistance box, there are great deficiencies.Since the resistance value of each resistance box requires may Be different, therefore, can only single production assembly, flexibility is low, can not produce in batches, and such manufacture looks forward to production Cost is high for industry, beyond affordability.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of structurally reasonable, resistance value is adjustable, is easy to A kind of Combined resistance box structure of assembly.
The technical scheme adopted by the utility model 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 utility model are as follows:
In the utility model, pedestal is cooperated to form a new resistance box structure by resistance unit, and then realize for not With the assembly for the resistance box that resistance value requires, first, the circle of resistance wire winding can be passed through using the structure of ceramic rod winding resistance wire Number adjusts the resistance value of single resistance unit, second, the resistance unit of respective numbers and resistance box are embedded in cooperation, can be realized Resistance value requirement to resistance box, simple installation is low in cost, easy to disassemble, adaptable;
In the utility model, the terminal plate of each resistance unit is symmetrically installed per adjacent two resistance unit backwards to being arranged, is For the ease of the series connection and installation of resistance unit;The ceramic rod for the convex block cooperation resistance unit produced in pedestal is fixed, and tears open Dress is easy, can quickly assemble;The structure of pedestal and shell activity installation, then be to operate for the ease of staff, going here and there Shell can be removed when joining resistance unit, then by outer cover suit in chassis outer side after the completion of connecting, improve the safety of resistance box Property.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of resistance unit;
Fig. 2 is the structural schematic diagram of pedestal;
Fig. 3 is the structural schematic diagram of resistance box.
Specific embodiment
Below with reference to embodiment, the present invention will be further described, and it is not limited that following embodiments, which are illustrative, , the protection scope of the utility model cannot be limited with following embodiments.
A kind of Combined resistance box structure, including multiple resistance units, each resistance unit include a hollow ceramic rod 2, the both ends of ceramic rod are respectively installed with a terminal plate 1, and the ceramic rod outer rim uniform intervals between two terminal plates are wound with resistance Silk 4, the innovation of the utility model is, multiple resistance units are vertically installed at respectively in a pedestal 6, adjacent two resistance unit it Between it is in sequential series, a terminal plate of two resistance unit on the outermost side is connect with external circuit respectively.
In the present embodiment, the terminals of each terminal plate are formed with through-hole 3.
In the present embodiment, two terminal plate arranged in dislocation of the resistance unit, backwards to setting.
In the present embodiment, it is symmetrically mounted in pedestal per two adjacent resistance units, is used between two ipsilateral terminal plates The connection sheet that one conductive material is produced mutually is installed.
In the present embodiment, uniform intervals produce multiple circular convex blocks 7 in the upper surface of the pedestal, each convex block it is outer Diameter is adapted with the internal diameter of the ceramic rod inner edge of resistance unit, and ceramic rod is sleeved on the outside of convex block in the mounted state.
In the present embodiment, a circle boss 8, the pedestal outer rim above the boss are produced in the outer rim lower end of the pedestal outward Outer sheath is equipped with a shell 9.
In the present embodiment, in the adaptable position in the surface of shell and the terminal plate of outermost two resistance unit, respectively A mounting hole is produced, connector is protruded into the mounting hole and is attached with two terminal plates.
The course of work of the utility model is:
When the utility model produces, operator can require to produce according to required resistance value, and basis is accordingly wanted first Division resistance value is sought, corresponding resistance value unit is produced, multiple resistance value units is set on the outside of corresponding convex block carries out later Fixed, adjacent resistance unit is attached by installation connecting element later, carries out shell and pedestal after the completion of to be installed Assembling can be completed in fixation.
In the utility model, pedestal is cooperated to form a new resistance box structure by resistance unit, and then realize for not With the assembly for the resistance box that resistance value requires, first, the circle of resistance wire winding can be passed through using the structure of ceramic rod winding resistance wire Number adjusts the resistance value of single resistance unit, second, the resistance unit of respective numbers and resistance box are embedded in cooperation, can be realized Resistance value requirement to resistance box, simple installation is low in cost, easy to disassemble, adaptable;
In the utility model, the terminal plate of each resistance unit is symmetrically installed per adjacent two resistance unit backwards to being arranged, is For the ease of the series connection and installation of resistance unit;The ceramic rod for the convex block cooperation resistance unit produced in pedestal is fixed, and tears open Dress is easy, can quickly assemble;The structure of pedestal and shell activity installation, then be to operate for the ease of staff, going here and there Shell can be removed when joining resistance unit, then by outer cover suit in chassis outer side after the completion of connecting, improve the safety of resistance box Property.
