Description
Technical field
The utility model relates to a kind of high-performance spark coil that is applicable to motor car engine.
Background technique
Existing spark coil is poor in functional reliability, is mainly manifested in existing spark coil using process and easily has mis-ignition phenomenon, and it has strengthened the wearing and tearing of motor and the discharge of harmful gas.And, the habitual scolding tin mode of Placement of HV Terminal structure, its cost is higher, and reliability is not fully up to expectations.And whole spark coil exists static to eliminate and lacks antijamming capability.
Model utility content
The purpose of this utility model is exactly in order to address the above problem, and a kind of functional reliability, high-performance spark coil that antijamming capability is strong are provided.
To achieve these goals, the utility model adopts following technological scheme:
High-performance spark coil, it comprises:
Cage assembly (1), it has coil installs cavity and with coil, the installation passage that cavity communicates and arrange for HV Terminal is installed, and this installation passage is provided with HV Terminal (6);
Be installed on coil installation cavity and an end and be connected to the primary air assembly (4) of controller, the secondary winding assembly (3) coordinating with primary air assembly, iron core assembly (5), described cage assembly is provided with the plug assembly (2) to primary air assembly (4) power supply; Described secondary winding is connected to high-voltage diode (K), and described HV Terminal is connected in secondary winding assembly by deformed spring (8).
Further, described iron core assembly (5) is installed on motor car engine by stretching out the external part attachment screw (7) of cage assembly.
The utlity model has following beneficial effect: the functional reliability of whole high-performance spark coil is higher, and antijamming capability is strong, is in particular in:
First, by accessing high-voltage diode at secondary winding, carry out the mis-ignition of control engine, when the switch connection of controller is during moment, the magnetic field of iron core changes, secondary winding meeting Voltage-output, current direction is now just contrary, now high-voltage diode blocking-up backward current, and whole secondary winding is open-circuit condition, high-voltage output end just can not produce high pressure, and motor just can not mis-ignition.
Moreover, by HV Terminal is installed with the mode of structure of heterotypic spring, can effectively save cost, be convenient to install, improve reliability.
Accompanying drawing explanation
Fig. 1 is high-performance spark coil electrical schematic diagram.
Fig. 2 is high-performance ignition coil structure schematic diagram.
Fig. 3 is HV Terminal structure place fragmentary detail view.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As Figure 1-3, high-performance spark coil, it comprises: cage assembly 1, it has coil installs cavity and with coil, the installation passage that cavity communicates and arrange for HV Terminal is installed, and this installation passage is provided with HV Terminal 6; Being installed on coil installs cavity and an end and is connected to controller (this controller sends instruction by automobile ECu and controls, and primary air assembly 4, the secondary winding assembly 3 coordinating with primary air assembly, iron core assembly 5 curent change of the switch of this controller control primary air assembly), described cage assembly is provided with the plug assembly 2 to 4 power supplies of primary air assembly; Described secondary winding is connected to high-voltage diode K, and described HV Terminal is connected in secondary winding assembly by deformed spring 8.
Referring to Fig. 1, one end of former secondary winding assembly is connected to the circuit that vehicle power "+" is extremely gone up, increases by an anti-high-voltage diode, carry out the mis-ignition of control engine, when the switch connection of controller is during moment, the magnetic field of iron core changes, secondary winding meeting Voltage-output, and current direction is now just in time contrary, and anti-high-voltage diode K blocking-up backward current, whole secondary winding is open-circuit condition, and high-voltage output end just can not produce high pressure, and motor can be avoided mis-ignition.
Referring to Fig. 2, described iron core assembly 5 is installed on motor car engine by stretching out the external part attachment screw 7 of cage assembly.
The high-performance spark coil that this case provides is that vehicle power (low-voltage dc power supply of 6-16V) is powered to primary air assembly 4 by the connecting sheet of plug assembly 2, the another end of primary air is connected to controller, make primary air assembly form a loop, and controller is to send control command by automobile ECU, the switch of controller is being controlled the curent change of primary air assembly, when electric current changes, make the variation of the iron core assembly 5 generation magnetic flux of closed magnetic circuit, the induction electromotive force changing, corresponding secondary winding assembly 3 just produces high voltage, the HV Terminal 6 of secondary winding assembly is connected on spark plug by high voltage wire, ignition mixture in some gas cylinder, and the other end of secondary winding assembly connects "+" level of an anti-high-voltage diode and vehicle power and is connected, comparatively speaking, be equal to ground connection, secondary winding total performance is a complete loop like this.Aforementioned plug assembly, primary and secondary coil assembly are put into cage assembly, the packing that embedding is required, then the mounting hole by iron core assembly is fixed on motor by screw, the static that so just iron core can be produced is by motor ground connection, eliminate static, play jamproof effect.
Omit in full the description for known technology.
The foregoing is only preferred implementation of the present utility model, protection domain of the present utility model is not limited in above-mentioned mode of execution, and every technological scheme that belongs to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, some improvement of carrying out under the prerequisite that does not depart from principle of the present utility model, these improvement also should be considered as protection domain of the present utility model.
