Description

  The present invention relates to an electronic component and an electronic device including the electronic component, and more particularly to an electronic component including a coil therein and an electronic device including the electronic component.

  Conventionally, as an effective means for increasing the impedance of a circuit, there is a method of inserting an LC parallel resonant circuit and electrically separating a low impedance portion of the circuit. Hereinafter, with reference to FIG. 6, a description will be given of increasing the impedance of the circuit by the LC parallel resonance circuit. FIG. 6 is an explanatory diagram for explaining a circuit for realizing high impedance by an LC parallel resonant circuit.

  As shown in FIG. 6, the circuit 60 includes a low impedance circuit 61, a low impedance circuit 62, and an LC parallel resonance circuit 63. The low impedance circuit 61 and the high impedance circuit 62 configure the LC parallel resonance circuit 63. It is the structure connected via. The high impedance circuit 62 includes a signal detection circuit (not shown). The LC parallel resonant circuit 63 has a configuration in which a coil L and a capacitor C are connected in parallel.

  In the circuit 60, the resonance frequency of the LC parallel resonance circuit 63 is matched with the frequency of a signal pulse or the like whose impedance is to be increased. When the pulse signal is input to the circuit 60, resonance occurs in the LC parallel resonance circuit 63, and as a result, the impedance is high with respect to the signal frequency. At this time, in the circuit 60, the circuit viewed from the input (IN) is only the high impedance circuit 62, and the impedance becomes high.

  In such a circuit 60, when the power consumption is large (for example, 500 mA or more), the direct current flowing through the coil L of the LC parallel resonance circuit 63 becomes large. As the direct current increases, the size of the coil L increases. A large coil is vulnerable to shocks such as dropping. Therefore, when a strong impact is applied to the circuit 60, the position of the coil L may be shifted, or the core of the coil L may be broken. Such a problem is not limited to an electronic component having an LC parallel circuit, but is a problem that occurs in all electronic components having a coil.

  In order to avoid such a problem, in an electronic component having a conventional coil, the coil and the upper lid for closing the circuit including the coil are made of cushioning strong double-sided tape or the like so that the coil does not move. They are pasted together.

Patent Document 1 states that “an outer conductor whose cross section perpendicular to the signal propagation direction has a predetermined shape, and a plurality of low impedance portions and a plurality of high impedance portions provided in the outer conductor alternately. In a low-pass filter including a repeated inner conductor and an input / output unit connected to an end of the inner conductor, the dimension of the cross section perpendicular to the signal propagation direction of the outer conductor is varied depending on the position in the signal propagation direction. A low pass filter is disclosed. Thereby, reduction of the influence of the spurious resonance peak, vibration resistance, and impact resistance are achieved.

  However, when the coil and the upper lid that closes the circuit including the coil are bonded together using a strong cushioning double-sided tape or the like, once the upper lid is closed, the upper lid cannot be opened. Therefore, it is inconvenient when a circuit in the electronic component fails and it is desired to repair the circuit.

  Even if the upper lid can be opened, the cushioning double-sided tape tears, making it difficult to return the electronic component to its original state.

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide an electronic component having a coil that can be easily opened when a circuit is repaired. The object is to provide an electronic device equipped.

  The electronic component of the present invention includes a housing having a coil therein. And it has an opening part in the housing | casing, and a cover member covers the opening part.

  In the conventional electronic component, since the lid member is bonded to the coil and covers the opening, it is difficult to open the lid member when repairing the inside of the casing. However, according to the above configuration, the lid member is provided with the holding portion that holds the coil only when the opening portion is covered, so that the electronic component is assembled. Later, for example, when repairing the inside of the housing, the lid member can be easily opened.

  The electronic component according to the present invention preferably includes a plurality of coils, and the plurality of coils are held by only one holding portion.

  According to the above configuration, since only one holding part is held by the plurality of coils, it is compared with a case where each holding part is held for each of the plurality of coils. Thus, the number of parts is small, and the configuration is simpler, and the trouble of preventing the shift movement of the plurality of coils is reduced.

  In the electronic component of the present invention, it is preferable that the holding portion includes a fitting portion that fits the coil.

  According to said structure, after assembling an electronic component, when repairing the inside of an electronic component, for example, it becomes possible to open a cover member easily by peeling off a surface fastener.

  Moreover, according to said structure, since it is not necessary to form the fitting part which fits a coil, compared with the case where the said holding part is equipped with the fitting part which fits the said coil, it is an electronic component. The coil and the lid member can be separated from each other while maintaining the appearance.

  Moreover, in the electronic component of the present invention, it is preferable that a roughening process is performed on the opposing surfaces of the holding portion and the coil.

  “Rough surface processing” refers to a process in which irregular irregularities are formed on the surface.

  According to said structure, since the rough surface processing is performed, it becomes possible to prevent that a coil shifts | deviates by the friction of the surfaces where the said holding part and the said coil mutually oppose.

  Further, the number of parts can be reduced as compared with a configuration in which the holding portion includes an attachment / detachment member for attaching / detaching the coil. Therefore, it is possible to realize an electronic component that can increase the impact resistance and can easily open the lid member at a lower cost.

  The electronic component of the present invention preferably further includes an impact absorbing member that absorbs an external impact.

  According to said structure, an impact-absorbing member absorbs the impact from the outside. For this reason, when an electronic component falls or vibrates, the impact of the coil is absorbed.

  When roughening the surface of the holding portion and the coil facing each other, the surface of the shock absorbing member is roughened so that the shock absorption of the coil It is possible to have both functions of preventing slippage movement, and the number of parts is small and the configuration is simpler.

  In particular, when the roughening process is performed on the surfaces where the holding portion and the plurality of coils face each other, and the same holding portion holds the plurality of coils, According to the configuration, the adjacent coils of the plurality of coils can interact with each other to further prevent the plurality of coils from shifting.

  In the electronic component of the present invention, it is preferable that the shock absorbing member is an elastic body.

  When the size of the coil is large and the weight is heavy, the shock absorbing member may be extremely deformed and the shock absorbing action may be weakened. According to said structure, since the said shock absorption part contains the elastic body, even if it is a case where the size of a coil is large and weight is heavy, a shock absorption effect | action can be maintained.

  Further, the plastic plate 4 is attached to the coil 2 via the impact absorbing portion 3, but is not attached to the upper lid 5. That is, the plastic plate 4 can be attached to and detached from the upper lid 5 by fitting with the plastic plate 4.

The following will describe another embodiment of the present invention with reference to FIG. Configurations other than those described in the present embodiment are the same as those in the first embodiment. For convenience of explanation, members having the same functions as those shown in the drawings of the first embodiment are given the same reference numerals, and explanation thereof is omitted. FIG. 2 is a cross-sectional view showing a schematic configuration of the electronic component of the present embodiment.

  The electronic component of the first embodiment has a configuration in which a fitting portion for fitting a coil is provided, whereas the electronic component in the embodiment is provided with an attaching / detaching portion for attaching / detaching the coil to / from the lid member. It is a configuration.

  As shown in FIG. 2, in the electronic component 20, the shock absorber 3 is provided on the surface facing the upper lid 25 of the coil 2. A hook-and-loop fastener 24 is provided between the shock absorber 3 and the upper lid 25. The surface fastener 24 includes a male member 24 a provided on the upper surface of the impact absorbing portion 3 and a female member 24 b provided on the lower surface of the upper lid 25. The male member 24a and the female member 24b are detachable from each other on the opposing surfaces. The “surface fastener” refers to a male member and a female member that are configured to be detachable in a surface unit. For example, as a hook-and-loop fastener, there is a tape that can be attached and detached freely on a surface-by-surface basis using a pile. More specifically, a magic tape (trademark registration) is mentioned.

  As described above, in the electronic component 20, the female member 24 b is provided on the coil 2, and the hook-and-loop fastener 24 is formed together with the male member 24 a provided on the upper lid 5. Therefore, after assembling the electronic component 20, for example, when repairing a circuit inside the electronic component 20, the upper lid 25 can be easily opened by peeling the hook-and-loop fastener 24.

  Moreover, in the electronic component of the first embodiment, since the concave portion formed in the shape of a plastic plate is formed on the upper lid, the appearance of the electronic component may change. On the other hand, the electronic component of this embodiment is provided with a hook-and-loop fastener without the need to bother to form a recess in the upper lid. Therefore, in the electronic component of the present embodiment, the coil and the upper lid can be separated while maintaining the appearance.

In addition, the dimension of the board | substrate 1, the impact-absorbing part 23, the hook_and_loop | surface fastener 24, and the upper cover 25 in the electronic component 20 can be suitably set according to the size of the coil 2, or the use application of an electronic component.
[Embodiment 3]
The following will describe still another embodiment of the present invention with reference to FIGS. Configurations other than those described in the present embodiment are the same as those in the first and second embodiments. For convenience of explanation, members having the same functions as those shown in the drawings of Embodiments 1 and 2 are given the same reference numerals, and explanation thereof is omitted. FIG. 3 is a cross-sectional view showing a schematic configuration of the electronic component of the present embodiment. FIG. 4 is a cross-sectional view schematically showing another configuration of the electronic component of the present embodiment.

  As shown in FIG. 3, the electronic component 30 of the present embodiment has an impact absorbing portion (lid supporting portion) 34 a and an impact absorbing portion (coil supporting portion) on the surfaces where the coil 2 and the upper lid (lid member) 35 face each other. Part) 34b.

  The shock absorbers 34a and 34b absorb external shocks. For this reason, when the electronic component 30 falls or vibrates, the impact of the coil 2 is absorbed. For this reason, it can prevent that the core of the coil 2 cracks.

  Further, the surfaces I and II where the shock absorbing portion 34a and the shock absorbing portion 34b face each other are finished to be uneven so that the friction between the surfaces increases. That is, rough surface processing is performed. For this reason, since the coil 2 and the upper lid 35 are supported to such an extent that they can be separated, the upper lid 35 can be easily opened after the electronic component 30 is assembled, for example, when the circuit inside the electronic component 30 is repaired. Is possible. Further, it is possible to prevent the coil 2 from moving due to the friction between the surface I and the surface II. Moreover, since it is not necessary to provide a hook-and-loop fastener as compared with the electronic component of the second embodiment, the number of components can be reduced. Therefore, it is possible to realize an electronic component that can improve impact resistance and easily open the lid member at a lower cost.

  Further, as the impact absorbing portions 34a and 34b, the configuration of the “impact absorbing portion 3” mentioned in the first embodiment can be mentioned, and among them, cushioning sponge and rubber are preferably used. In the case of using a cushioning sponge, the sponge needs to have an appropriate hardness in order to withstand vibration caused by dropping of an electronic component.

  Further, when the size of the coil is large and the weight is heavy, if a cushioning sponge is used, the sponge may be extremely deformed and the impact absorbing function may be weakened. On the other hand, the cushioning rubber has higher hardness than the sponge, so that even when the coil size is large and the weight is heavy, the shock absorbing action can be maintained. Therefore, depending on the weight of the coil core, it may be better to use a rubber having a higher hardness than a cushioning sponge.

  Note that the dimensions of the substrate 1, the shock absorbing portion 34a and the shock absorbing portion 34b, and the upper lid 35 in the electronic component 30 can be appropriately set according to the size of the coil 2 or the use application of the electronic component. .

  In FIG. 3, the shock absorbing portions 34 a and 34 b are the same size, but in the electronic component of the present embodiment, there is a portion where the shock absorbing portions are in contact at least between the coil and the lid member. If it is such a structure, it will not specifically limit. For example, the structure from which the size of the upper surface of the impact-absorbing part provided in the cover member and the coil differs is mentioned. In this case, since any one of the shock absorbing portions provided on the lid member and the coil is recessed into the other, the friction between the shock absorbing portions is further increased.

  In the electronic component 30, the shock absorbing part 34 a is larger than the size of the upper surface of the coil 2. However, the electronic component of the present embodiment is not limited to this, and the impact absorbing portion 34a may be smaller than or the same size as the upper surface of the coil 2.

  Further, for example, the shock absorbing portion 34a has a donut shape so that the upper surface of the coil 2 is exposed even if the shock absorbing portion 34a is provided so as to cover the upper surface of the coil 2 when viewed from the lid member side. It may be provided as follows.

  In addition, the electronic component of the present embodiment may have a configuration in which an impact absorbing member is provided on one of the surfaces where the coil and the lid member face each other. In this case, the surface of the shock absorbing portion is finished to be uneven, and the other surface is finished to be uneven, so that the friction between the surface of the shock absorbing portion and the other surface is increased. Hereinafter, a configuration in the case where an impact absorbing portion is provided on the surface of the coil facing the lid member will be described with reference to FIG.

  As shown in FIG. 4, in the electronic component 40, an impact absorbing portion 44 is provided on the surface facing the upper lid 45 of the coil 2. Further, the surface III facing the upper cover 45 of the impact absorbing portion 44 is subjected to a rough surface processing. On the other hand, the lower surface of the upper lid 45, that is, the surface IV facing the coil 2 of the upper lid 45 is subjected to a rough surface processing. For this reason, the upper lid 45 can be easily opened when the circuit inside the electronic component 40 is repaired. Further, it is possible to prevent the coil 2 from shifting due to the friction between the surface III and the surface IV.

  In the electronic component 30, the shock absorbing portion is provided on the lower surface of the upper lid 35, but in the electronic component 40, the lower surface of the lid member is finished to be uneven instead of providing the shock absorbing portion on the lower surface of the lid member. . Therefore, the electronic component 40 can reduce the number of components compared to the electronic component 30. In addition, it is possible to realize an electronic component that can increase the impact resistance and can easily open the lid member at a lower cost.

  FIG. 4 shows a configuration in which the shock absorbing portion 44 is provided on the upper surface of the coil 2. However, the present invention is not limited to this, and the surface of the coil facing the lid member is subjected to a rough surface processing treatment. The structure which provided the impact-absorbing part in the surface facing a coil, and gave the roughening process to the surface facing a coil of an impact-absorbing part may be sufficient.

Further, the “rough surface processing” refers to a process in which irregular irregularities are formed on the surface. Examples of such a “rough surface processing” method include a method of finishing the surface roughly (texture).

In the electronic component 50, the plastic plate 54 is fitted in the recess 55a. For this reason, even when the electronic component 50 is dropped or vibrated, the plastic plate 54 does not fit into the recess 55a, and the plurality of coils 2a, 2b, and 2c do not move.

  Further, the plastic plate 54 is attached to the plurality of coils 2 a, 2 b, 2 c via the shock absorbing portion 53, but is not attached to the upper lid 55. That is, the plastic plate 54 can be separated from the upper lid 55. For this reason, after assembling the electronic component 50, for example, when repairing a circuit inside the electronic component 50, the upper lid 55 can be easily opened.

  Further, the electronic component 50 is configured such that one plastic plate 54 fits into the recess 55a with respect to the plurality of coils 2a, 2b, and 2c. For this reason, the electronic component 50 has a simpler configuration with a smaller number of parts compared to a case where the electronic component 50 is individually fitted to each of the plurality of coils, and has the trouble of preventing the displacement movement of the plurality of coils. Reduced.

  In addition, in FIG. 6, the cover member has been described as having a configuration in which a single fitting convex member is provided on a plurality of coils, but the electronic component of the present embodiment is not limited to this, and the plurality of coils is not limited thereto. On the other hand, the structure provided with the same attachment / detachment part may be sufficient.

  Moreover, the structure by which the roughening process was given to the surface where a some coil and cover member mutually oppose may be sufficient.
