Its structure of pen-type ignition coil mainly comprises coil block, is connected to the output electrode assembly of coil block high-voltage output end, iron clad, is sleeved on rubber sheath and the radome of output electrode component external successively.Coil block is that ignition coil is introduced low pressure, exported the core component of high pressure, comprise iron core, be sleeved on the high-tension coil of its outside successively, low-voltage coil, connect the high-field electrode of high-tension coil output, be sleeved on the housing of low-voltage coil skeleton outside and be positioned at the low pressure input of housing upper end.The packaging technology of pen-type ignition coil is after above-mentioned coil block, the assembling of low pressure input, finally encapsulates from housing upper port encapsulated epoxy resin.For ensureing sealing, preventing epoxy leaks, require that each parts connecting portion is connected and sealed.For this reason, existing low-voltage framework with need by smearing epoxy resin or glue is fixedly connected with housing seal between housing, the mode but this kind is tightly connected, complex operation, manually, material etc. consume large, production efficiency is lower, and affects the interior quality of product appearance and ignition coil, is especially unfavorable for the automation realizing pen-type ignition coil packaging technology.The Hermetical connecting structure how improving above-mentioned employing epoxy resin or glue becomes industry concerned issue.
In addition, low-voltage framework is equipped with ground strip, iron clad is connected by the earth terminal of ground strip with low pressure input.But existing ground strip to continue after assembling in operation by the via hole that inserts on low-voltage framework and carry out adhesive sealing to fix, adopt separately that another dress operation is more complicated, efficiency is low, especially in hole, retains gap, embedding hourglass material, directly affects sealing effectiveness.
Utility model content
Main purpose of the present utility model is for the problems referred to above, provides a kind of pen-type ignition coil adopting sealing ring seal casinghousing, and then, also on housing, be wholely set ground strip, thus realize Simplified flowsheet, time saving and energy saving province material, improve sealing effectiveness, improve the quality of products and production efficiency.
The utility model solves the technical scheme that its technical problem adopts:
Adopt a pen-type ignition coil for sealing ring seal casinghousing, mainly comprise coil block, be connected to the output electrode assembly of coil block high-voltage output end, iron clad, be sleeved on rubber sheath and the radome of output electrode component external successively; Coil block comprise iron core, the high-tension coil being sleeved on its outside successively, low-voltage coil, connection high-tension coil output high-field electrode, be sleeved on the housing of low-voltage coil skeleton outside and be positioned at the low pressure input of housing upper end, it is characterized in that arranging ring week groove in described low-voltage coil skeleton bottom outside, described low-voltage coil skeleton is connected with described housing seal by the sealing ring be inlaid in described ring week groove.
Described housing is sandwich shell, and at case top integrated injection molding one ground strip, the earth terminal of ground strip upper end and low pressure input is welded to connect, and ground strip lower end compresses to contact with the iron clad upper end of inserting in sandwich shell and connects.
The beneficial effects of the utility model are: low-voltage coil skeleton is connected with housing seal by sealing ring.The sealing means adopting in prior art and smear epoxy resin or glue is instead of with sealing ring, simple to operation, Simplified flowsheet, time saving and energy saving province material, and improve reliability and sealing effectiveness, improve outward appearance, enhance productivity.In addition, by ground strip integrated injection molding on housing, avoid the drawback connecting separately the ground strip position leakage material that ground strip causes, same Simplified flowsheet, reduces costs, and enhances productivity, and improves sealing effectiveness.The utility model may be used on the product of similar structures.
