Our e-rod provides the placement of the power source and the wiring in the handle. This has minimized the dimensions of the rods and the weight. The use of variable resistor enables in the time of fishing to give a "nod" different vibrational frequency from 50 to 300 in minute.
Application the relay type RES-9 (PC passport 4524202) allows to reduce the consumption of current up to 12-14 mA, the supply voltage can be from 2 to 4.5 V.
Fig. 1. The electric circuit of the rods
The electrical circuit (Fig. 1) is placed on the Board of Micarta size 55x18x1,5 mm and mounted in a plastered dural tube is the tube inner diameter of 18 mm (Fig. 2). The power supplies are located inside a special frame; contacts - one stationary, the other movable on the spring.
Relay, circuit Board with the bosses, batteries, variable resistor and rear cover represent a single unit, and the relay circuit Board and the boss are glued together. The cone and the casing is also cemented.
This design will facilitate repair fishing rods and replace or recharge the batteries.
Fig. 2. The rod design: 1 - cone (tree); 2 - housing (tube); 3 - tube 20x18 mm, length 126 mm (duralumin); 5 - spring (steel wire, d=0.5 mm); 6 - batteries D-02; 7 - bushing (plated hardened paper or the PCB): 8 - cover (tree); 9 - handle variable resistor; 10 - variable resistor STRs 51; 11 - pin M3; 12 - contact (bronze plate); 13 - tube (plated hardened paper); 14 - pin (brass); 15 - boss (plated hardened paper): 16 to the mounting plate; 17 - boss (plated hardened paper); 18 - relay RES-9; 19 - bushing (brass); 20 - whip.
