Abstract
The utility model discloses a box type capacitor having magnetic beads. The box type capacitor having the magnetic beads comprises a box type capacitor, two annular magnetic beads and a casing, wherein the casing comprises a groove in matching with the box type capacitor body, the box type capacitor body is mounted in the groove of the casing, the two annular magnetic beads are respectively sleeved on two pins of the box type capacitor, a top face of the annular magnetic beads is lower than a top face of the groove, the groove is bonded with bonding glue, and the annular magnetic beads, the box type capacitor and the casing are bonded together through the bonding glue. The box type capacitor can settle a problem of labor-hour consuming in mounting the magnetic beads on the capacitor pins in a production process, subsequent assembling work is reduced, and the box type capacitor is attractive integrally, has strong practicality and is quite convenient for large-scale production.
Description
[technical field]
The utility model relates to capacity cell, relates in particular to a kind of boxlike electric capacity with magnetic bead.
[background technology]
In electronic product, usually for the noise jamming of filter out power circuit to system, often increase an inductance or magnetic bead in power supply output, the noise bringing with filter out power circuit, and improve the performance of EMC.Annular magnetic bead is often directly enclosed within on two pins of boxlike electric capacity, and as shown in Figure 1, annular magnetic bead cover 2 rear some glue on two pins 101 of boxlike electric capacity 1 is fixed, and in the process that the device of this need of work before circuits assembly prepared, fulfils ahead of schedule.Discrete magnetic bead be enclosed within on pin be operated in a large amount of production time there is time-consuming problem of taking a lot of work, the outward appearance of boxlike electric capacity is because the glue-line 3 of a glue is excessive attractive in appearance not.
[summary of the invention]
The technical problems to be solved in the utility model is to provide a kind of good looking appearance, the boxlike electric capacity with magnetic bead can save assembler time.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of boxlike electric capacity with magnetic bead comprises boxlike electric capacity, two annular magnetic beads and shell, described shell comprises the groove with boxlike electric capacity body adaptation, and the body of boxlike electric capacity is encased in the groove of shell; Two annular magnetic beads are enclosed within respectively on two pins of boxlike electric capacity, and the end face of annular magnetic bead is lower than the end face of groove; In groove, have bonded adhesives, annular magnetic bead, boxlike electric capacity and shell are bonded as one by bonded adhesives.
The above-described boxlike electric capacity with magnetic bead, fills with and has described bonded adhesives in groove, and the end face of bonded adhesives is lower than the end face of groove.
The above-described boxlike electric capacity with magnetic bead, described groove is step groove, and the height of step is greater than the height of boxlike electric capacity body, and annular magnetic bead is seated on the step of groove.
The above-described boxlike electric capacity with magnetic bead, described shell is injection casing.
The utility model can solve the working expenditure man-hour problem of magnetic bead to capacitor pin is installed aborning with the boxlike electric capacity of magnetic bead, has reduced follow-up assembly work, and electric capacity overall appearance is practical, very convenient in the time of a large amount of production.
[brief description of the drawings]
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the schematic diagram that prior art boxlike capacitor pin overlaps discrete installation magnetic bead process.
Fig. 2 is the structural representation of the utility model embodiment with the boxlike electric capacity of magnetic bead.
[embodiment]
The utility model embodiment with the structure of the boxlike electric capacity of magnetic bead as shown in Figure 2, comprises boxlike electric capacity 1, two annular magnetic beads 2 and shells 4.
Shell 4 is thin-walled injection moulding part, has a groove with step, and the groove of step below and the shape of boxlike electric capacity 1 body are suitable; The body of boxlike electric capacity 1 is encased in the groove of shell 4 step belows, and the height of step is greater than the height of boxlike electric capacity 1 body.
Two annular magnetic beads 2 are enclosed within respectively on two pins 101 of boxlike electric capacity 1, and the bottom surface of annular magnetic bead 2 is seated on the step of groove.
The end face of annular magnetic bead 2 is lower than the end face 401 of groove.In groove, be filled with bonded adhesives 3, annular magnetic bead 2, boxlike electric capacity 1 and shell 4 are bonded as one by bonded adhesives 3.The end face 301 of bonded adhesives 3 is lower than the end face 401 of groove.
Boxlike electric capacity manufacturing process with magnetic bead is as follows: after electric capacity 1 completes, electric capacity 1 is put into the groove of shell 4, two pins 101 of electric capacity 1 put respectively 2 magnetic beads 2, finally casting glue 3 are poured in box body, and electric capacity 1, magnetic bead 2 and housing 4 are firmly fixed together.
The above embodiment of the utility model utilizes housing that magnetic bead and electric capacity are combined effectively with the boxlike electric capacity of magnetic bead, can solve the working expenditure man-hour problem of magnetic bead to capacitor pin is installed aborning, reduce follow-up assembly work, electric capacity overall appearance, practical, very convenient in the time of a large amount of production, EMC performance is also better.
