Installing electrode and its corresponding spring structure connection of configuration, the design of shell both ends has screw thread to be tightened with fixed lid cooperation, keeps away
Exempting from traditional graphite flake fixed form, there are limitations, after by surge impact, the graphite flake of stacking and its insulation
Gap will not loosen, and properties of product decline is caused even to fail, and meet power supply over all Integration, volume miniaturization, power
It is maximized to need, it is convenient for high-density arrangement element circuitry plate, has saved cost, improved work efficiency.
Technical solution used by the utility model has：
It is a kind of for fixing the structure of graphite flake and its clearance for insulation, including shell, fixed lid, fixing clamp, electrode, bullet
Spring, graphite flake, clearance for insulation, it is characterised in that：The several groups graphite flake and clearance for insulation stack combinations is placed in circle
In the insulation crust of shape, the fixing clamp is uniformly distributed fixation, the fixation along graphite flake and clearance for insulation surrounding
Design has trapezium structure slot on folder, and positioned at the both ends of graphite flake and clearance for insulation, there are also corresponding installation electrode, the electricity
Spring is installed, the shell both ends design has screw thread, and fixed lid is tightened with shell cooperation between pole and fixed lid.
The shell is circular cylindrical cavity structure, and fastening thread is arranged in both ends, is located at screw thread there are electrode fairlead,
The fixed lid is tightened with shell cooperation, and the graphite flake is round or polygon；The electrode is located at graphite
Between piece and spring, one end is connected with graphite flake, lower end be arranged a pin be directly welded on circuit board, be located at electrode with
Spring is configured between fixed lid.
The fixing clamp is semicircle plastic part, and centre has trapezium structure slot, for fixing between graphite flake and insulation
Gap material, if dry plate fixing clamp is uniformly wrapped in graphite flake surrounding and fixes.
The utility model has the advantages that：
The technical program is used to fix the structure of graphite gaps, changes graphite flake and its clearance for insulation and is passing through surge impact
It later can be there is a phenomenon where there is loosening, by being equipped with this problem of spring very good solution, bullet between electrode and fixed lid
Spring use applies pressure to graphite flake and its clearance for insulation at both ends, and it is firm to guarantee that it is adjacent to, meanwhile, pin can directly weld
On circuit boards, it solves graphite flake and its clearance for insulation to be easy to loosen after surge impact that properties of product is caused to reduce even
The problem of failure.
