Description
Technical field
The utility model relates to injection molding fields, and in particular to a kind of transformer device structure of anti-seepage of resin.
Background technique
Automobile ignition coil is important component indispensable in electronic engine management system, is by the low tension on vehicle
Switch to a kind of transformer of high-voltage electricity, ignition coil is made of plastic shell, high-head, skeleton etc., and shell is to pass through injection molding machine
Machine-shaping, and high-head is that a metalwork is installed in plastic part, metalwork and plastic part circular hole gluing, sealing part
Cylindrical surface is a complete plane, and the circular hole for assembling metalwork communicates completely with the cavity of installing skeleton.In order to mention
The insulation effect of high transformer, when plastic part and metalwork after the assembly is completed, the components such as skeleton must be packed into the cavities then
Pour into resin.In filling resin process, since resin passes through the pressure of capillary phenomenon and liquid level, often from plastic part and metal
Outer surface is slowly penetrated into the gap of the fitting of part and forms buildup of resin, to cause subsequent not assembling.
Summary of the invention
The utility model is to solve the above-mentioned problems, and to design a kind of transformer device structure of anti-seepage of resin, by
A block baffle is arranged in skeleton cavity and inserts assembly cavity, and metalwork and the seal section of inserts assembly cavity fitting part are arranged
Groove, so that resin crawls into plastic part when filling resin into skeleton cavity and the binding face distance of metalwork extends, to have
Effect prevents resin from penetrating into product appearance by capillary phenomenon.
The utility model is realized by following scheme: the transformer device structure of this anti-seepage of resin includes plastic, gold
Belonging to part and terminal, one end of the plastic has the cavity for putting high low pressure skeleton, and the other end of the plastic has an assembly
The inserts assembly cavity of metalwork, between the cavity and the inserts assembly cavity be equipped with a block baffle, and keep the cavity with
Be connected between the inserts assembly cavity, the terminal by the insertion of hole between baffle and inserts assembly cavity and with the metalwork
The seal section of clamping, the metalwork and inserts assembly cavity fitting part has groove, and it is close that the groove is located at metalwork
It seals among section, the depth of the groove is a quarter of diameter of sealed section, and the width of the groove is the three of seal section height
/ mono-.
Preferably, in order to more prevent seepage of resin, the groove is arranged 2 or more, and the sum of the width of the groove is
The half of seal section height.
Preferably, metalwork is blocked for the ease of terminal, the terminal is flexible Y type.
Compared with prior art, the benefit of the utility model is: resin is by penetrating into inserts assembly cavity from skeleton cavity
When, due to the obstruction by middle baffle plate and terminal, the process for penetrating into inserts assembly cavity is slack-off, when resin penetration to inserts fills
It after chamber, due to the pressure of capillary phenomenon and liquid level, is slowly permeated from the gap of plastic part and metalwork, when resin arrival is set
After the groove of meter, temporary stop can be done here, after resin fills up groove, can just be seeped again by capillary phenomenon
Thoroughly, at this moment resin has solidified substantially, will not infiltrate from the gap of the fitting of plastic part and metalwork again, this external cause increases
Baffle is added, contact of the terminal with metalwork becomes stronger.
Detailed description of the invention:
Fig. 1 is the utility model structure diagram；
Fig. 2 is terminal structure schematic diagram；
Fig. 3 is original product structural schematic diagram；
In figure: 1, plastic, 11, cavity, 12, inserts assembly cavity, 13, baffle, 2, metalwork, 21, seal section, 22, groove,
3, terminal
Specific embodiment:
The utility model is described in detail with reference to the accompanying drawings and detailed description:
A kind of transformer device structure of anti-seepage of resin according to figure 1 includes plastic 1 and metalwork 2, the plastic 1
There is the cavity for putting high low pressure skeleton 11 in one end, and the other end of the plastic 1 has the inserts assembly cavity of an assembly metalwork
12, a block baffle 13, the cavity 11 and the inserts assembly cavity are equipped between the cavity 11 and the inserts assembly cavity 12
It is connected between 12, the terminal 3 passes through the hole insertion between baffle 13 and the inserts assembly cavity 12 and blocks with the metalwork 2
It connects, the seal section 21 of the metalwork 2 and 12 fitting part of inserts assembly cavity has groove 22, and the groove 22 is located at gold
Belong among part seal section 21, the depth of the groove 22 is a quarter of 21 diameter of seal section, and the width of the groove 22 is
The one third of 21 height of seal section.
Another preferred embodiment, the difference is that the groove 22 is arranged 2 or more, the sum of the width of the groove 22
For the half of 21 height of seal section.
Another preferred embodiment, the difference is that the terminal 3 is flexible Y type.
It is emphasized that: the above is only the preferred embodiment of the present utility model, not appoints to the utility model
What formal limitation, any simple modification made by the above technical examples according to the technical essence of the present invention, etc.
With variation and modification, it is still within the scope of the technical solutions of the present invention.
