Description

The inductor improved structure

Technical field:

The utility model is relevant a kind of inductor improved structure, refers to a kind of solder joint area and terminal area of making especially, far beyond the inductor improved structure of dust head's increase.

Background technology:

Press, the failure cause of traditional inductor assembly, may start because of in: one, the resistance of solder joint is too high, and especially when being used in the product of big electric current, higher solder joint resistance more easily generates heat; Two, the terminal area is too little, and the resistance of terminal is big, then when big electric current passes through, easily produces superheating phenomenon; Three, the coil heat radiation is difficult for, and the heat of coil also can't effectively be directed to outside heat radiation, so the easy deterioration of coil; Four, the solder joint area is little, and mechanical structure is not firm, and scolding tin may run off and form the space, comes in contact bad easily and fault; When five, solder joint resistance and terminal resistance are big, also cause the extra power loss of battery, reduce the useful life of battery relatively; Be desirable part to the greatest extent to be arranged so that, traditional inductor structure is real.

Edge this, this creator is because of because the many practical shortcoming of taking off on the product commonly used, actively design and actual tests develop then and the utility model inductor improved structure that can significantly promote its practical effect.

Summary of the invention:

So main creation purpose of the present utility model promptly is to provide a kind of inductor improved structure; Utilize the window and the platform of terminal unit, make that the solder joint area between coiling unit and terminal unit is significantly increased.

Of the present utility model time one creation purpose is to be to provide a kind of inductor improved structure; Wherein, when the solder joint area between coiling unit and terminal unit increases, it is lower then to weld formed solder joint resistance, the heating phenomenon of coiling unit, can give the outer heat radiation of drawing by the big area of dissipation that terminal unit had, and effectively reduce temperature rise, prevent the coiling unit deterioration, to be applicable to occasions such as big electric current.

Another creation purpose of the present utility model is to be to provide a kind of inductor improved structure; Wherein, when the solder joint area between coiling unit and terminal unit increased, then the mechanical structure of inductor was more firm, and contact is good, and scolding tin is difficult for running off.

A creation purpose more of the present utility model is to be to provide a kind of inductor improved structure; This terminal unit is not increasing under the inductor integral thickness, can reach bigger terminal area, and therefore, terminal unit has less resistance value and less in caloric value when the electric current, simultaneously, and has bigger area of dissipation.

The utility model is further created purpose, is to be to provide a kind of inductor improved structure; Wherein, because solder joint resistance significantly reduces, and terminal unit has less resistance value, and then the electric power that inductor consumed also can significantly reduce, thus can further save the consumption of battery, and between the operating period of prolongation battery.

The utility model is in order to reach above-mentioned purpose and effect, and in the inductor of open-flux path formula, the technological means that it adopted comprises an outer cover unit, a coiling unit, reaches pair of terminal unit etc.; Wherein:

This outer cover unit is made of integrated shell body, and has a hollow slotted eye;

This coiling unit is made of an axis magnetic winding one flatwise coil, and flatwise coil also has two coil terminals, can insert from the hollow slotted eye of shell body, and be fixedly arranged on the inside of outer cover unit;

This terminal unit, constituted by a sheet metal, appropriate position on the side end face has a window that can supply two coil terminals to pass, and the lower end of window has a platform, and be provided with a upper end bending segment and a lower end bending segment, and the inboard spacing of platform and lower end bending segment is the lower frame thickness more than or equal to shell body;

By this, platform and lower end bending segment can be clamped on the lower frame jointly, and the upper end bending segment can support and terminate in upper side frame, make terminal unit to set firmly mutually with outer cover unit, and two coil terminals are after paint removal, can be welded on window around, the bottom of two coil terminals and can being welded on the platform, and then reach a bigger solder joint area and a terminal area.

After adopting such scheme, the utlity model has following beneficial effect against existing technologies: the topmost intention spirit of the utility model is to provide a kind of inductor improved structure, be window 310 and the platform 32 that utilizes this terminal unit 30, make the solder joint area of 30 of coiling unit 20 and terminal units be increased, and this terminal unit 30, do not increasing the following of inductor integral thickness, can reach bigger terminal area, therefore, but the mechanical structure of inductor is firm, radiating effect is promoted and can save consume, and the life-saving of battery power.

For further understanding feature of the present utility model, technological means and the concrete function of being reached, purpose, enumerate now of the present utility model than specific embodiment, continue describe in detail with graphic, figure number as after:
