Abstract

A kind of anti-iron core abjection structure of pen type coil, including a hollow coil rack, the coil rack head opening and shell wall are equipped with several hooks in opening upwards, cored, iron core cushion is placed in the coil rack from top to bottom, the coil rack head cover is equipped with a core cap, the core cap is equipped with number and shape and the consistent hook hole of hook, and the hook tips upside down on across hook hole and fixes core cap on core.The utility model has the beneficial effects that: coil rack upper end opening sets lid, in order to install and secured core, because the gap size between the control iron core that can be had a margin and shell, obtains reliable product quality.

Description

A kind of anti-iron core abjection structure of pen type coil

Technical field

The utility model relates to a kind of anti-iron cores to deviate from structure.

Background technique

When earlier general pen type coil assembly iron core, directly iron core is inserted into high pressure skeleton hole and carries out magnetic conduction, iron core exists The very slight close-fitting in high pressure skeleton hole loosens plunger position fixation not.

But in fact, iron core is that slices stack, iron core diameter's precision is difficult to control, and iron core is inserted into high pressure skeleton When slightly tight some, after ignition coil work generates heat, iron core expands the matter easily burst high pressure skeleton and generate breakdown Amount problem, thus be security consideration, it is packed into pine a bit, but this loose fit, so that Chang Fashengyin iron core is deviate from production process, Position is inconsistent, so that ignition coil performance parameter is inconsistent, performance parameter is undesirable when serious and generates punch through damage.

Summary of the invention

In order to overcome the shortcomings of that the installation of prior art pen type iron-core coil is easily broken down, the utility model provides one kind The anti-iron core of pen type coil deviates from structure.

The technical scheme in the invention for solving the technical problem is: a kind of anti-iron core abjection structure of pen type coil, including One hollow coil rack, the coil rack head opening and shell wall are equipped with several hooks in opening upwards, Cored, iron core cushion is placed in the coil rack from top to bottom, the coil rack head cover is equipped with a core cap, institute Core cap is stated equipped with number and shape and the consistent hook hole of hook, the hook is tipped upside down on core cap across hook hole and fixed Core cap.

Further, toward cover rim is had on the downside of the core cap, the inner cavity on coil rack head expands in order to cover rim insertion Positioning is equipped with encapsulating gap between the cover rim and inner cavity.It is accurate to be positioned such that, encapsulating is convenient.

Further, several card muscle are equipped on the outside of the cover rim to be stuck in coil rack head side wall.

A kind of preferred, the hook and hook hole are respectively provided with two.

To prevent from shaking, the coil rack head is additionally provided with positioning card point upwards, and the core cap is equipped with location hole, institute It states positioning card point and is caught in positioning hole.

Iron core is first put into coil rack by the utility model when in use, is iron core cushion above iron core, is then covered Upper core cap compacting finally carries out encapsulating and realizes encapsulation.

The utility model has the beneficial effects that: 1, coil rack upper end opening sets lid, in order to install and secured core, Because the gap size between the control iron core that can be had a margin and shell, obtains reliable product quality.

Fig. 2 is the top view of the utility model.

Specific embodiment

The utility model seat is further described with reference to the accompanying drawings and detailed description

Embodiment 1

In conjunction with attached Fig. 1 and 2, a kind of anti-abjection of iron core 3 structure of pen type coil is described including a hollow coil rack 1 Coil rack head opening and shell wall set upwards in opening there are two hook 2, put from top to bottom in the coil rack 1 Be equipped with iron core 3, iron core cushion 4,1 head cover of coil rack is equipped with a core cap 5, the core cap 5 be equipped with number and Shape and the consistent hook hole 6 of hook 2, the hook 2 tip upside down on core cap across hook hole 6 and fix core cap 5.

Further, 5 downside of core cap expands toward cover rim 7, the inner cavity on 1 head of coil rack is had in order to cover rim 7 Insertion positioning, is equipped with encapsulating gap 8 between the cover rim 7 and inner cavity.It is accurate to be positioned such that, encapsulating is convenient.

Further, several card muscle 9 are equipped on the outside of the cover rim 7 to be stuck in 1 head side wall of coil rack.

A kind of preferred, the hook 2 and hook hole 6 are respectively provided with two.

To prevent from shaking, 1 head of coil rack is additionally provided with positioning card point 10 upwards, and the core cap 5 is equipped with positioning Hole, the positioning card point 10 are caught in positioning hole.

First iron core 3 is put into coil rack 1 when the present embodiment is in use, is iron core cushion 4 above iron core 3, then The compacting of core cap is covered, encapsulating is finally carried out and realizes encapsulation.

The beneficial effect of the present embodiment is: coil rack upper end opening sets lid, in order to install and secured core and iron Core cushion, because the gap size between the control iron core that can be had a margin and shell, obtains reliable product quality.

Claims
