The present embodiment provides an ignition coil assembly, which is applied to an engine of a vehicle.
As shown in fig. 1 to 3, the ignition coil assembly provided in this embodiment includes a high-voltage connector 1 and a connector 5, wherein a receiving cavity is formed in the high-voltage connector 1 and the connector 5; the high-voltage connector comprises a high-voltage connector 1, and is characterized by further comprising a suppression resistor 3 and a conductive elastic piece, wherein the suppression resistor 3 and the conductive elastic piece are both positioned in the accommodating cavity, and at least one end of the suppression resistor 3 is provided with the conductive elastic piece so as to electrically connect the high-voltage connector 1, the suppression resistor 3 and the connecting piece 5; at least part of the conductive elastic element is sleeved to the periphery of the suppression resistor 3 and is in contact with and fixed with the suppression resistor 3.
As can be seen from the above, in the ignition coil assembly provided in this embodiment, at least one end of the suppression resistor 3 is provided with the conductive elastic element, and since at least a part of the conductive elastic element is sleeved on the periphery of the suppression resistor 3 and is in contact with and fixed to the suppression resistor 3, the sleeved portion of the conductive elastic element increases the contact area with the suppression resistor 3, thereby effectively improving the signal transmission effect between the conductive elastic element and the suppression resistor 3; in addition, the conductive elastic element is sleeved on the suppression resistor 3, and the overlapped part of the conductive elastic element can enhance the overall structural strength of the suppression resistor 3, so that the suppression resistor 3 is prevented from being deformed by the vibration of an engine or the impact of external force.
It should be noted that, the end of the connecting piece 5 far away from the high-voltage connector 1 is used for connecting with a spark plug, and the connecting piece 5 can adopt the existing mature connecting structure form; the suppression resistor 3 in the present embodiment may be formed of a material that is conventionally used for interfering with an electromagnetic field, for example, a spirally wound filament made of an electromagnetic material, and a semiconductor material may be applied to the suppression resistor 3 as needed.
As shown in fig. 3, in some embodiments, the conductive elastic member is an existing mature high-voltage spring having a contact section 21 for contacting the resistance 3, and the contact section 21 is disposed to envelope the outer circumferential surface of the resistance 3. Here, the inner diameter of the contact section 21 of the spring should be substantially the same as the outer diameter of the suppressing resistor 3, or slightly larger than the outer diameter of the suppressing resistor 3, and when the contact section 21 envelopes the suppressing resistor 3, the outer circumferential surface of the suppressed resistor 3 is stretched and deformed, so that the contact section 21 of the conductive elastic member can be closely attached to the outer diameter of the suppressing resistor 3, and this arrangement can further ensure the signal transmission effect of the conductive elastic member and the suppressing resistor 3.
Further, the aforementioned contact section 21 is screw-fittingly connected with the suppression resistor 3. Here, since the conductive elastic member itself is a spring made of a conductive material spirally wound, the conductive elastic member may be directly pulled toward one end of the suppression resistor 3 to a pitch of the spring to match the thread groove.
In some embodiments, the number of the threaded connection turns of the contact section 21 and the suppression resistor 3 is 2-5, where the number of the threaded connection turns of the contact section 21 and the suppression resistor 3 may be 2, 3, 4, 5, etc., as long as the stable connection of the contact section 21 and the suppression resistor 3 can be ensured; it should be noted that in some embodiments, when the number of turns of the screw connection is small, the pitch may be increased to ensure the length of the overlapping portion of the contact section 21 and the suppression resistor 3; when the number of the threaded connections is large, the thread pitch can be reduced appropriately to avoid that the overlapping portion of the contact section 21 and the suppression resistor 3 is too long to affect the working performance of the suppression resistor 3.
Here, through the mode that adopts screw-thread fit to connect, the dismouting work that carries on that can be convenient between electrically conductive elastic component and the suppression resistance 3, because whole car electrical environment is different, the portable dismouting setting between electrically conductive elastic component and the suppression resistance 3 can change the suppression resistance 3 of corresponding different resistances according to the electrical environment of difference to be favorable to high efficiency's adaptation electrical environment. As an alternative embodiment, the conductive elastic element and the suppression resistor 3 may be connected by snapping or welding.
In some embodiments, the conductive elastic member is in a thread shape and comprises an elastic section capable of elastic expansion and contraction and a rigid inelastic section, wherein the inelastic section is sleeved on the periphery of the suppression resistor 3; the inelastic segment is here the segment in surrounding contact with the suppression resistor 3. Further, the elastic end and the non-elastic section are integrally formed, for example, by casting.
In some embodiments, the length of the overlapping portion of the contact segment 21 and the suppression resistor 3 is 1/5-1/3 of the total length of the suppression resistor 3, and specifically, the overlapping portion is the portion of the contact segment 21 sleeved in the suppression resistor 3, and the length of the overlapping portion may be 1/5, 1/4 or 1/3 of the total length of the suppression resistor 3, which enables the overlapping portion to function as a protection for the suppression resistor 3, and prevents the suppression resistor 3 from being offset and deformed by external impact or vibration, thereby preventing the normal use effect of the suppression resistor 3 from being affected.
In some embodiments, the high-voltage connector 1 is electrically connected with the suppression resistor 3 through the first conductive elastic member 2, the end of the connecting member 5 is electrically connected with the suppression resistor 3 through the second conductive elastic member 4, the first conductive elastic member 2 and the second conductive elastic member 4 can adopt the same spring structure and are connected to the suppression resistor 3 through the same connection mode, here, the conductive elastic members are arranged between the high-voltage connector 1 and the suppression resistor 3 and between the end of the connecting member 5 and the suppression resistor 3, so that the use stability of the ignition coil can be further improved, the abrasion caused by the vibration of the engine is reduced, and the service life of the ignition coil assembly is prolonged.
It should be noted that, in order to connect the first conductive elastic element 2 and the second conductive elastic element 4 to the suppressing resistor 3, two ends of the suppressing resistor 3 should be subjected to adaptive processing, for example, two ends of the suppressing resistor 3 are subjected to rough increase of inner diameter, so that the first conductive elastic element 2 and the second conductive elastic element 4 are connected to the suppressing resistor 3, the first conductive elastic element 2 and the second conductive elastic element 4 are sleeved on the rough part of the suppressing resistor 3, the structural strength of the suppressing resistor 3 can be further improved, and the connecting function of the first conductive elastic element 2 and the second conductive elastic element 4 is increased.
In some embodiments, the conductive elastic element may be disposed only at one end of the suppression resistor 3, or disposed at both ends of the suppression resistor 3, as long as the conductive elastic element and the suppression resistor 3 are connected in a socket connection manner.
In some embodiments, the first conductive elastic element 2, the suppressing resistor 3, and the second conductive elastic element 4 are electrically connected to form a total resistor, the resistance value of the total resistor is in a range of 0.5k Ω to 5k Ω, and specifically, the resistance value may be 0.5k Ω, 1k Ω, 2k Ω, 3k Ω, 4k Ω, 5k Ω, and the like.
In some embodiments, an inner diameter of an end of the first conductive elastic element 2 or the second conductive elastic element 4 away from the suppression resistor is tapered, specifically, other auxiliary components for connecting to the spark plug are further provided in the cavity of the connecting element 4, for example, the connecting rod 6, the second conductive elastic element 4 is connected in abutment with the connecting rod 6, here, in order to facilitate connection with the second conductive elastic element 4, a trapezoidal groove is correspondingly provided on the connecting rod 6, and the second conductive elastic element 4 with the tapered inner diameter can facilitate insertion into the trapezoidal groove of the connecting rod 6, thereby forming abutment fixation of the second conductive elastic element 4 in the connecting element 5.
