Description
Technical field
The utility model is related to technical field of automobile engine, and in particular to a kind of high pressure inserted sheet and provided with there is the high pressure
The pen-type ignition coil of inserted sheet.
Background technology
In automotive engine ignition system, ignition coil is a kind of for ignition engine cylinder air and fuel oil mixing
Thing provides the execution unit of ignition energy, and it is a kind of special burst transformer of electromagnetic induction principle, can turn low-voltage
Change the voltage of 25000V even more highs into.And high pressure inserted sheet is the high-pressure section and igniting cylinder body for connecting coil, so high pressure
The stability of inserted sheet is very important to ignition coil.
Such as the patent that notification number is CN205621594U, a kind of high-head circle of pen-type ignition coil which disclose
Inserted sheet bindiny mechanism, including circular inserted sheet and high pressure skeleton, circular inserted sheet connection corresponding with high pressure skeleton, circular inserted sheet are provided with
Inserted sheet stitch, high pressure skeleton is provided with groove, and inserted sheet stitch is correspondingly arranged with groove, and circular inserted sheet is provided with cross-hole, institute
The shaping of cross-hole surrounding is stated provided with four inserted sheet salient points, the distance of the two neighboring inserted sheet salient point is equal.The utility model
Using such structure setting, by being provided with inserted sheet stitch on circular inserted sheet, groove is provided with high pressure skeleton, then by inserting
Piece stitch is inserted in groove, is realized that circular inserted sheet is directly connected in high pressure skeleton purpose, is eliminated plug, save cost,
Effectively increase operating efficiency.
The shortcoming of the patent is:When mounted, the igniting cylinder body with HV Terminal need to be connected with high pressure skeleton,
In the cross-hole of the circular inserted sheet of now HV Terminal insertion, and with four inserted sheet bump contacts, and drive four inserted sheet salient points
Direction distortion is plugged to HV Terminal, so that inserted sheet salient point there are enough contacts area between HV Terminal, makes contact
Well.Can be seen that inserted sheet salient point is set in parallel circular inserted sheet from accompanying drawing, then HV Terminal when driving insertion sheet convex point deformation,
Inserted sheet salient point receives the upward power of vertical inserted sheet salient point, the concentrated stress for being easily subject to inserted sheet salient point and circular inserted sheet junction
It is excessive.Because concentrated stress is larger, therefore inserted sheet salient point can be rotated up along the junction of inserted sheet salient point and circular inserted sheet, cause to insert
Piece salient point reduces the contact area of HV Terminal and inserted sheet salient point, causes loose contact away from HV Terminal.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of high pressure inserted sheet, by that will insert
Set vertically in depression in the middle part of piece body, so as to form the first compensating tank, spark is compensated by the deformation of the first compensating tank
Plug and high pressure skeleton mismachining tolerance, it is ensured that when spark plug is tightened on high pressure skeleton, inserted sheet body just with spark plug
Abut.
To achieve the above object, the utility model provides following technical scheme：
