For achieving the above object, the utility model proposes a kind of ignition coil, comprise iron core, secondary coil, primary coil, shell, upper cover and base plate, described iron core lower end is provided with projection, described base plate is provided with corresponding groove, described projection and groove fit are installed, on described iron core sidewall, cover has secondary coil, outside described secondary coil, cover has primary coil, shell is provided with outside described primary coil, described shell upper end is provided with upper cover, the end face of described upper cover is provided with protruding post, described protruding post and upper cover are formed in one, described protruding post inside is provided with high-voltage line and connects post, the two ends of described upper cover are provided with two low tension terminals be arranged symmetrically with, described low tension terminal is provided with additional resistance joint.
As preferably, described secondary coil one end is connected with primary coil, and the secondary coil other end and high-voltage line connect post and be connected, and described primary coil one end is connected with low tension terminal, and the primary coil other end is connected with external switch device.
As preferably, between described secondary coil and primary coil, be provided with epoxy resin layer.
As preferably, described low tension terminal is bolted on the upper surface of upper cover, and described high-voltage line connects the inside that post is fixed on upper cover.
The beneficial effects of the utility model: the utility model is by the setting of primary coil and secondary coil, thus produce higher induced voltage, the energy that external spark plug obtains is also higher, ignition results is good, adopt the setting of additional resistance joint, the electric current of input is changed by changing access resistance, and then change the induced voltage exported, controllability is high, safe and reliable, upper cover adopts insulating material, and internal high pressure line can be made to connect post and exterior insulation, improve safe performance, long service life.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
