Abstract
The utility model relates to a low temperature rise ignition coil of high energy belongs to combustion engine ignition source technical field. The ignition coil is mainly characterized in that the existing ignition coil is improved, an open type iron core is changed into a semi-open type iron core, the length of the iron core is increased, a low-voltage and high-voltage electric connecting post is remotely arranged, other corresponding measures are taken, the ignition energy is increased by more than 2 times compared with the existing ignition coil through trial, the maximum flashover voltage is increased by 0.5 time, the temperature rise in continuous operation is reduced by more than 10 ℃, and the effect is obvious.
Description
The utility model belongs to combustion engine incendiary source technical field, is the low temperature rise spark coil of a kind of high-energy.
Its iron core of existing spark coil is open iron core, and iron core is shorter, and conventional lengths is 95mm, and its high-tension electricity wiring terminal and low tension wiring terminal are at same end, and it is less to exist firing energy, and temperature rise is higher, the shortcoming that the incompatibility high-energy ignition needs.
The purpose of this utility model is to design a kind of high-energy ignition and the lower spark coil of temperature rise.
The technical measures that the utility model is taked are improved existing spark coil: the length that 1, increases iron core; 2, change open iron core into the semi open model iron core; 3, high-tension electricity wiring terminal and low tension wiring terminal are moved remote layout, and other corresponding measure, guaranteeing firing energy, maximum sparking voltage significantly surpasses former spark coil, and temperature rise is lower than former spark coil.
Reach the structure characteristic that example further specifies the low temperature rise spark coil of the utility model high-energy in conjunction with the accompanying drawings.
Accompanying drawing is represented the structural representation of the low temperature rise spark coil of the utility model high-energy.
Referring to accompanying drawing, the low temperature rise spark coil of the utility model high-energy comprises high-tension electricity wiring terminal 1, Bakelite Cover 2, iron core 4, concentrating flux sleeve 5, secondary windings 6, elementary winding 7, insulation porcelain cup 8, additional resistance 10, low tension wiring terminal 11, shell 12; Install magnetic guiding loop 3 additional in iron core 4 upper ends, magnetic guiding loop is to be changed by the above silicon steel ring plate of one deck, installs magnetic conducting plate 9 additional in iron core 4 lower ends, and magnetic conducting plate is changed by the above silicon steel disk of one deck, constitutes the semi open model iron core.Length on the iron core 4 is risen to 120-220mm by traditional length 95mm; Low tension wiring terminal 11 is moved on to bottom (on the bottom or side of shell 17) by the top (on the Bakelite Cover 2) of spark coil.When said structure changes, take to increase iron core 4 cross sections and corresponding increase concentrating flux sleeve 5, measures such as the number of plies of minimizing primary air or the number of turn.
Behind the iron core lengthening,, under the constant situation of air gap length, can reduce magnetic resistance because the air gap width increases, thereby can reduce the number of turn of primary and secondary coil, also can increase coil height and every layer of number of turn, so both can reduce the D.C. resistance of primary and secondary coil, can reduce the copper cash amount of using again.After changing iron core into the semi open model iron core, the air gap total length is reduced greatly, magnetic resistance reduces, thereby reduce the number of turn of primary and secondary coil, and the major part magnetic flux constitutes the loop between magnetic guiding loop, magnetic conducting plate, concentrating flux sleeve, the Magnetic leakage flux of iron core central authorities is less relatively, stray flux distribution improves and helps to improve inductance, the secondary wire number of plies can significantly reduce like this, and copper consumption can reduce 1/2-1/3, and secondary D.C. resistance can reduce.High-tension electricity wiring terminal and low tension wiring terminal are moved layout far away, and the energy consumption that the discharge that not only can avoid causing owing to strong electrical field between the high low pressure electric wiring terminal causes weakens spark energy and sparking voltage, and avoids bakelite breakdown.
The low temperature rise spark coil of the utility model high-energy that adopts such scheme to make, through on probation, use condition is good, firing energy increases more than 2 times than existing spark coil, maximum sparking voltage can reach more than 30,000 volts, improves 0.5 times, and the continuous operation temperature rise reduces more than 10 °.
