Description

本発明は、電子機器の筐体などに部品を取り付ける部品取付構造に関する。   The present invention relates to a component mounting structure for mounting a component to a housing or the like of an electronic device.

従来、電子機器において、トランスなどの電気部品を筐体などに取り付ける構造として、筐体に切り絞り部が設けられ、その切り絞り部にトランスの取付部を係合させ、切り絞り部に係合していない取付部を筐体にネジ止めすることによって、トランスを筐体に取り付ける構造が下記特許文献１に開示されている。しかし、このような構造では、電気部品の取り付け位置の周囲に、取付部を切り絞り部に係合させるために電気部品を回転させるスペースが必要である。また、このような構造では、筐体の内側からネジ止めするので、ネジ止め後にネジ先端が筐体外へ突き出してしまい、外観面でも安全面でも好ましくない。そこで、電気部品の取付部の複数箇所を、補助金具を筐体外からネジ固定し、補助金具と筐体とで電気部品の取付部を挟持させることによって、電気部品を筐体に取り付ける構造がある。しかし、このような構造においては、ネジ止めの際に補助金具が共回りしてしまうので、ネジ止めの際に治具を使用しなければならず、作業性が悪い。   2. Description of the Related Art Conventionally, in electronic devices, as a structure for attaching an electrical component such as a transformer to a housing or the like, a cut-off part is provided in the case, and the attachment part of the transformer is engaged with the cut-off part and engaged with the cut-off part Patent Document 1 below discloses a structure for attaching a transformer to a housing by screwing a mounting portion that is not attached to the housing. However, in such a structure, a space for rotating the electrical component is necessary around the mounting position of the electrical component in order to cut the mounting portion and engage the throttle portion. Further, in such a structure, since the screw is fixed from the inside of the housing, the screw tip protrudes outside the housing after screwing, which is not preferable in terms of appearance and safety. Therefore, there is a structure in which the electrical component is attached to the casing by fixing the auxiliary bracket with screws from outside the casing and sandwiching the mounting portion of the electrical component between the auxiliary bracket and the casing at a plurality of locations of the electrical component mounting section. . However, in such a structure, since the auxiliary metal fittings rotate together when screwing, a jig must be used when screwing, and workability is poor.

さらに、取付具１００ａは、強度を高めるために取付具１００ａの側辺１０８（接続部１０２において鉤部１０４ａ、１０４ｂが規定される側辺１０２ａと逆側の側辺を含む取付具１００ａにおける側辺）に折返し部１０９が形成されている。この折返し部１０９によって、当接部１０１ａと当接部１０１ｂとの間の距離（接続部１０２の長さ）を長く規定した場合であっても、折返し部１０９によって補強されるので、取付具１００ａが変形することがない。   Furthermore, in order to increase the strength of the fixture 100a, the side of the fixture 100a includes the side 108 of the fixture 100a (including the side opposite to the side 102a where the flanges 104a and 104b are defined in the connecting portion 102). ) Is formed with a folded portion 109. Even when the distance (the length of the connecting portion 102) between the contact portion 101a and the contact portion 101b is specified to be long by the folded portion 109, the folded portion 109 reinforces the fitting 100a. Will not be deformed.

次に、トランス３００を、取付具１００ａによって筐体２００に仮止め後、ネジ４００ａ、４００ｂによって筐体２００に取り付ける工程を図３および４を参照して説明する。図３は、筐体２００にトランス３００を当接させたときの平面図である。図４は、取付具１００ａによってトランス３００を仮止めしたときの、図１中の矢印Ｂ方向から見たとき（ａ）と矢印Ｃからみたとき（ｂ）の部品取付構造の要部側面図である。図５は、取付具１００ａでトランス３００を仮止め後、筐体２００を裏返したときの部品取付構造である。   Next, a process of temporarily attaching the transformer 300 to the housing 200 with the fixture 100a and attaching the transformer 300 to the housing 200 with screws 400a and 400b will be described with reference to FIGS. FIG. 3 is a plan view when the transformer 300 is brought into contact with the housing 200. 4 is a side view of the main part of the component mounting structure when viewed from the direction of arrow B in FIG. 1 (a) and when viewed from arrow C (b) when the transformer 300 is temporarily fixed by the mounting tool 100a. is there. FIG. 5 shows a component mounting structure when the housing 200 is turned upside down after temporarily fixing the transformer 300 with the mounting tool 100a.

まず、トランス３００の取付部３０２を、筐体２００に規定されている凸部２０２ａ、２０２ｂに合わせて筐体２００に当接させる（図３）。そして、取付具１００ａの鉤部１０４ａ、１０４ｂを筐体２００に規定される取付孔２０１ａ、２０１ｂに挿入し、鉤部１０４ａ、１０４ｂの先端部１０７ｂが筐体２００に係止できるように取付具１００ａを、図４中に示す矢印の方向にスライドさせるとともに、筐体２００に規定されている凸部２０２ａ、２０２ｂを切欠部１０５、１０６に係入し、当接部１０１ａ、１０１ｂをトランス３００の取付部３０２に当接させる（図４）。このとき、切欠部１０５は凸部２０２ａの幅Ｌ４に対し十分な切り欠き幅Ｌ２を有しているので、凸部２０２ａを無理なく切欠部１０５に係入することができる。一方、切欠部１０６は、凸部２０２ｂの高さが低いので、凸部２０２ｂの厚みＬ６と略同一な切り欠き幅Ｌ５であっても、凸部２０２ｂを切欠部１０６に係入することができる。なお、取付具１００ａによってトランス３００が仮止めされた状態のとき、トランス３００の取付部３０２は、取付具１００ａの当接部１０１ａ、１０１ｂと筐体２００との間に介在し、取付具１００ａのネジ孔１０３ａ、トランス３００の挿通孔３０３ａおよび筐体２００の挿通孔２０２ａの中心が同軸上に位置し、取付具１００ａのネジ孔１０３ｂ、トランス３００の挿通孔３０３ｂおよび筐体２００の挿通孔２０２ｂの中心が同軸上に位置する（図示せず）。   First, the mounting portion 302 of the transformer 300 is brought into contact with the housing 200 in accordance with the convex portions 202a and 202b defined in the housing 200 (FIG. 3). Then, the flanges 104 a and 104 b of the fixture 100 a are inserted into the attachment holes 201 a and 201 b defined in the housing 200, and the fixture 100 a so that the tip portions 107 b of the flanges 104 a and 104 b can be locked to the housing 200. 4 is slid in the direction of the arrow shown in FIG. 4, the convex portions 202 a and 202 b defined in the housing 200 are engaged with the notches 105 and 106, and the contact portions 101 a and 101 b are attached to the transformer 300. It is made to contact | abut to the part 302 (FIG. 4). At this time, the notch 105 has a sufficient notch width L2 with respect to the width L4 of the protrusion 202a, so that the protrusion 202a can be easily engaged with the notch 105. On the other hand, since the height of the convex part 202b is low in the notch part 106, even if the notch width L5 is substantially the same as the thickness L6 of the convex part 202b, the convex part 202b can be engaged with the notch part 106. . When the transformer 300 is temporarily fixed by the fixture 100a, the attachment portion 302 of the transformer 300 is interposed between the contact portions 101a and 101b of the fixture 100a and the housing 200, and the fixture 100a The centers of the screw hole 103a, the insertion hole 303a of the transformer 300, and the insertion hole 202a of the housing 200 are located on the same axis, and the screw hole 103b of the fixture 100a, the insertion hole 303b of the transformer 300, and the insertion hole 202b of the housing 200. The center is located on the same axis (not shown).

本実施例では、ネジ４００ａ、４００ｂを筐体２００の外側から取り付ける構造であるので、ネジ４００ａ、４００ｂを取付具１００ａに取り付ける際に、作業者がネジ４００ａ、４００ｂを取り付けやすいように筐体２００を裏返す場合がある。このような場合、図５（ａ）に示すように、取付部３０２が筐体２００から離れ、当接部１０１ａ、１０１ｂに加重するが、鉤部１０４ａ、１０４ｂが先端部１０７ｂで筐体２００を係止することによって取付具１００ａが筐体２００に掛止されるので、トランス３００を仮止めすることができる。また、図５（ｂ）の右図に示すように、上部平面視において、取付部３０２が鉤部１０４ａ、１０４ｂの基端部１０７ａ、１０７ａを通る軸Ｋ−Ｋ’を越えて接続部１０２側まで延伸されていないとき、図５（ｂ）の左図に示すように、側面視において、取付具１００ａが鉤部１０４ａ、１０４ｂの先端部１０７ｂの端部を支点に（鉤部１０４ａ、１０４ｂの先端部１０７ｂの端部を通る軸Ｏ−Ｏ’を中心に）図中の矢印の方向に回動するが、取付具１００ａの側辺１０８が筐体２００に当たって取付具１００ａの回動を係止するので、取付具１００ａからトランス３００の取付部３０２が外れずに、トランス３００は仮止めされる。   In this embodiment, since the screws 400a and 400b are attached from the outside of the housing 200, the housing 200 is provided so that an operator can easily attach the screws 400a and 400b when attaching the screws 400a and 400b to the fixture 100a. May be turned over. In such a case, as shown in FIG. 5A, the attachment portion 302 is separated from the housing 200 and weights the contact portions 101a and 101b, but the flange portions 104a and 104b are attached to the housing portion 200 by the tip portion 107b. Since the fixture 100a is hooked on the housing 200 by being locked, the transformer 300 can be temporarily fixed. Further, as shown in the right view of FIG. 5 (b), in the top plan view, the attachment portion 302 passes through the base end portions 107a and 107a of the flange portions 104a and 104b and passes through the axis KK ′ and is on the connection portion 102 side. 5 (b), when viewed from the side, the fixture 100a uses the end of the tip 107b of the flanges 104a, 104b as a fulcrum (as shown in the left view of FIG. 5B). It rotates in the direction of the arrow in the figure (centering on the axis OO ′ passing through the end of the tip 107b), but the side 108 of the fixture 100a hits the housing 200 to lock the rotation of the fixture 100a. Therefore, the transformer 300 is temporarily fixed without the attachment portion 302 of the transformer 300 being detached from the fixture 100a.

次に、図１および６を参照してネジ４００ａ、４００ｂを取り付ける工程を説明する。図６は、図１中の矢印Ｂから見て、ネジ止め前の状態（ａ）およびネジ止め後の状態（ｂ）の部品取付構造の要部側面図である。また、図１（ａ）には、ネジ４００ａ、４００ｂを取り付ける際の回転方向（矢印ＤおよびＥ）が示されている。なお、ネジ４００ａ、４００ｂは筐体２００の外側から挿入されるので、筐体２００の内側から見た平面図である図１（ａ）において、ネジ４００ａ、４００ｂの回転方向は反時計回りである。   Next, a process of attaching the screws 400a and 400b will be described with reference to FIGS. FIG. 6 is a side view of the main part of the component mounting structure in a state before screwing (a) and a state after screwing (b) as seen from the arrow B in FIG. FIG. 1 (a) shows the rotation direction (arrows D and E) when the screws 400a and 400b are attached. Since the screws 400a and 400b are inserted from the outside of the housing 200, the rotation direction of the screws 400a and 400b is counterclockwise in FIG. 1A, which is a plan view seen from the inside of the housing 200. .

トランス３００を、取付具１００ａによって筐体２００に仮止めした後、ネジ４００ａを筐体２００の外側から筐体２００の挿通孔２０２ａ（図６には図示せず）およびトランス３００の挿通孔３０３ａ（図６には図示せず）を挿通させ、取付具１００ａのネジ孔１０３ａに螺合させる（図６）。ネジ４００ｂも同様に、筐体２００の外側から筐体２００の挿通孔２０２ｂおよびトランス３００の挿通孔３０３ｂを挿通させ、取付具１００ａのネジ孔１０３ｂに取り付ける（図示せず）。これにより、トランス３００の取付部３０２が筐体２００と取付具１００ａの当接部１０１ａ、１０１ｂとで挟持され、トランス３００が筐体２００に取り付けられる。ネジ４００ａ、４００ｂを取付具１００ａに取り付ける際、切欠部１０５が凸部２０２ａによって係止され、切欠部１０６が凸部２０２ｂによって係止されているので、ネジ４００ａ、４００ｂそれぞれを取り付ける際に取付具１００ａが共回りすることがない。また、ネジ４００ｂを取付具１００ａのネジ穴１０３ｂに取り付ける場合は、鉤部１０４ａ、１０４ｂが鉤孔２０２ａ、２０２ｂに係止されることによっても取付具１００ａの供回りを防止している。   After the transformer 300 is temporarily fixed to the housing 200 with the fixture 100a, a screw 400a is inserted into the insertion hole 202a (not shown in FIG. 6) of the housing 200 and the insertion hole 303a (not shown in FIG. 6) from the outside of the housing 200. 6 is inserted and screwed into the screw hole 103a of the fixture 100a (FIG. 6). Similarly, the screw 400b is inserted through the insertion hole 202b of the housing 200 and the insertion hole 303b of the transformer 300 from the outside of the housing 200 and attached to the screw hole 103b of the fixture 100a (not shown). Accordingly, the mounting portion 302 of the transformer 300 is sandwiched between the housing 200 and the contact portions 101a and 101b of the mounting tool 100a, and the transformer 300 is attached to the housing 200. When attaching the screws 400a and 400b to the fixture 100a, the notch 105 is locked by the convex portion 202a, and the notch 106 is locked by the convex portion 202b. Therefore, when the screws 400a and 400b are attached, the fixture 100a does not rotate together. Moreover, when attaching the screw 400b to the screw hole 103b of the fixture 100a, the rotation of the fixture 100a is also prevented by locking the flange portions 104a and 104b to the flange holes 202a and 202b.

ネジ止め後は、図６に示すように、ネジ止め前に筐体２００を係止していた鉤部１０４ａ、１０４ｂの先端部１０７ｂが、筐体２００から距離Ｈ１だけ離れる。従って、筐体２００と先端部１０７ｂとが接触して新たな振動が発生することがない。特に、本発明に係る部品取付構造をオーディオ機器に適用した場合、振動の発生に起因する音質の劣化を防止することができる。   After screwing, as shown in FIG. 6, the distal end portions 107b of the flanges 104a and 104b that have locked the housing 200 before screwing are separated from the housing 200 by a distance H1. Therefore, the housing 200 and the tip end portion 107b do not come into contact with each other to generate new vibration. In particular, when the component mounting structure according to the present invention is applied to an audio device, it is possible to prevent deterioration in sound quality due to the occurrence of vibration.

以上、本発明に係る部品取付構造は、取付具が筐体に掛止されることにより、部品の取付部が当接部と筐体との間に介在されるので、部品を筐体に仮止めすることができ、さらにはネジ止めの際に取付具が供回りすることを防止できるので、作業性に優れ、確実に部品を取り付けることができる。   As described above, in the component mounting structure according to the present invention, since the mounting portion of the component is interposed between the abutting portion and the housing when the mounting tool is hooked to the housing, the component is temporarily mounted on the housing. Since it can be stopped, and further, it is possible to prevent the attachment tool from turning around when screwing, so that it is excellent in workability and can securely attach components.

また、本発明に係る部品取付構造において、取付具の接続部に２つの鉤部を形成するようにしたが、その限りではなく、１または複数の鉤部を形成し、取付具を筐体に掛止できれば良い。   Further, in the component mounting structure according to the present invention, the two hook portions are formed at the connecting portion of the fixture, but this is not a limitation, and one or a plurality of hook portions are formed, and the fixture is attached to the casing. It only has to be hooked.

また、本発明に係る部品取付構造において、鉤部を挿入する鉤孔を、取付具の接続部に形成した鉤部の数だけ規定したが、その限りではなく、複数の鉤部を挿入することができる鉤孔を１つだけ規定しても良い。好ましくは、取付具の接続部に形成した鉤部の数と同じ数の鉤孔を筐体に規定する。複数の鉤部を挿入することができるように鉤孔を１つだけ規定した場合、筐体に大きな鉤孔を規定することになり、筐体の強度が下がるからである   Further, in the component mounting structure according to the present invention, the number of the hook holes for inserting the hook parts is defined by the number of the hook parts formed in the connection part of the fixture, but not limited thereto, and a plurality of hook parts may be inserted. Only one fistula can be defined. Preferably, the same number of holes as the number of flanges formed in the connection part of the fixture is defined in the housing. This is because when only one fistula is defined so that a plurality of collars can be inserted, a large fistula is defined in the casing, and the strength of the casing decreases.

また、本発明に係る部品取付構造において、取付具を略コ字型の平板形状にしたが、長方形の平板形状などであっても良い。好ましくは、取付具が略コ字型の平板形状である。トランスの本体が大きい場合であっても、本体が略コ字型の凹内まで配置させることができるからである。   Further, in the component mounting structure according to the present invention, the mounting tool has a substantially U-shaped flat plate shape, but may have a rectangular flat plate shape or the like. Preferably, the fixture has a substantially U-shaped flat plate shape. This is because even if the main body of the transformer is large, the main body can be disposed up to a substantially U-shaped recess.

また、本発明に係る部品取付構造において、ネジを筐体の外側から取り付けるようにしたが、筐体の外側にネジが突出しても外観上および／または安全上問題なければ、ネジを筐体の内側から取り付けるようにしても良い。その場合は、取付具の当接部に挿通孔を、筐体にネジ孔を規定する。   Further, in the component mounting structure according to the present invention, the screw is attached from the outside of the housing. However, if there is no problem in appearance and / or safety even if the screw protrudes from the outside of the housing, the screw is attached to the housing. You may make it attach from the inside. In that case, an insertion hole is defined in the contact portion of the fixture, and a screw hole is defined in the housing.
