本発明は、屋内の壁面等に設けられ、テレビ受像機にアンテナ受信信号を供給するテレビコンセントに関するものである。 The present invention relates to a television outlet provided on an indoor wall surface and the like for supplying an antenna reception signal to a television receiver.
屋内の壁面等に設けられるテレビコンセントには、テレビアンテナから入力側同軸ケーブルを介してアンテナ受信信号が供給され、そのアンテナ受信信号がテレビコンセントから出力側同軸ケーブルを介してテレビ受像機に供給される。 An antenna reception signal is supplied from a TV antenna via an input side coaxial cable to a TV outlet provided on an indoor wall surface or the like, and the antenna reception signal is supplied from the TV outlet to an television receiver via an output side coaxial cable. The
近年、テレビ放送の超高精細化に伴い、テレビコンセントに供給される受信信号のＩＦ周波数帯域は、３．２２４ＧＨｚまで広帯域化されている。しかし、この帯域は無線ＬＡＮ等の他の通信サービスの帯域と重なるため、干渉によるノイズが発生しやすい。 In recent years, with the ultra-high definition of television broadcasting, the IF frequency band of the received signal supplied to the television outlet has been widened to 3.224 GHz. However, since this band overlaps with the band of other communication services such as a wireless LAN, noise due to interference is likely to occur.
特許文献１には、テレビアンテナから受信信号が供給される入力側同軸ケーブルを、Ｆ型接栓を使用することなく接続する構成としたテレビコンセントが開示されている。このテレビコンセントでは、入力側同軸ケーブルと出力側同軸ケーブルを電気的に接続する接続金具を収容する筐体が、金属板を折り曲げて箱状に形成されている。 Patent Document 1 discloses a television outlet configured to connect an input-side coaxial cable to which a reception signal is supplied from a television antenna without using an F-type plug. In this television outlet, a housing that houses a connection fitting that electrically connects an input side coaxial cable and an output side coaxial cable is formed in a box shape by bending a metal plate.
特許文献１に開示されたテレビコンセントでは、入力側同軸ケーブルの芯線と、その芯線と電気的に接続される端子金具が電磁的にシールドされていないため、他の通信サービスの電磁波との干渉により発生するノイズの影響を受けやすくなっている。 In the television outlet disclosed in Patent Document 1, the core wire of the input side coaxial cable and the terminal fitting electrically connected to the core wire are not electromagnetically shielded, and therefore, due to interference with electromagnetic waves of other communication services. It is easy to be affected by generated noise.
Ｆ型接栓を使用して入力側同軸ケーブルをテレビコンセントに接続すると、シールド性は向上するが、筐体とＦ型接栓部がダイカストで一体に形成されるため、加工に労力を要するという問題がある。また、施工時にＦ型接栓をテレビコンセントにネジ着する作業が煩雑となる。 When the input side coaxial cable is connected to a TV outlet using an F-type plug, the shielding performance is improved, but the housing and the F-type plug part are integrally formed by die-casting, which requires labor for processing. There's a problem. Also, the work of screwing the F-type plug onto the TV outlet at the time of construction becomes complicated.
この発明はこのような事情に鑑みてなされたものであり、その目的は施工性がよく、外来ノイズに対するシールド性も確保し得るテレビコンセントを提供することにある。 The present invention has been made in view of such circumstances, and an object of the present invention is to provide a television outlet that has good workability and can secure shielding against external noise.
上記課題を解決するテレビコンセントは、Ｆ型接栓の芯線が接続される端子金具を収納する収納部、および、前記収納部を開口する開口部を有する筐体と、前記筐体の開口部を覆う金属製の蓋部材とを備え、前記蓋部材の周縁部は前記筐体の開口部の周縁部に接触する。 A television outlet that solves the above problems includes a storage unit that stores a terminal fitting to which a core wire of an F-type plug is connected, a housing that has an opening that opens the storage, and an opening of the housing. A cover member made of a metal to cover, and a peripheral portion of the cover member contacts a peripheral portion of the opening of the housing.
本発明のテレビコンセントによれば、施工性と外来ノイズに対するシールド性が高くなる。 According to the television outlet of the present invention, workability and shielding performance against external noise are enhanced.
以下、テレビコンセントの一実施形態を図面に従って説明する。図１〜図３に示すテレビコンセントは、入力側同軸ケーブルと出力側同軸ケーブルとを電気的に接続する端子金具を収容する筐体１と、筐体１の開口部を覆う蓋部材２が備えられる。 Hereinafter, an embodiment of a television outlet will be described with reference to the drawings. The TV outlet shown in FIGS. 1 to 3 includes a housing 1 that houses a terminal fitting that electrically connects an input-side coaxial cable and an output-side coaxial cable, and a lid member 2 that covers an opening of the housing 1. It is done.
図４に示すように、筐体１は亜鉛ダイキャストで長四角箱状に一体形成され、一方に向かって開口されている。なお、このテレビコンセントは、壁面に取り付けられるとき、筐体１が室外側に向かって開口するように取り付けられる。筐体１の上辺３及びその上辺３の両側に連なる側辺４の上部は、室外側に向かって延設されている。 As shown in FIG. 4, the housing 1 is integrally formed in a rectangular box shape by zinc die casting and is opened toward one side. In addition, when this television outlet is attached to a wall surface, it attaches so that the housing | casing 1 may open toward the outdoor side. The upper side 3 of the housing 1 and the upper part of the side 4 connected to both sides of the upper side 3 are extended toward the outdoor side.
筐体１の他方側の側面、すなわち室内側に向かう側面には円筒状の取付軸６が突出され、その取付軸６の外周面にはネジ７が刻設されて、Ｆ型接栓を螺合可能となっている。取付軸６の中央部に形成された透孔８は、筐体１内に連通している。 A cylindrical mounting shaft 6 protrudes from the other side surface of the housing 1, that is, the side surface facing the indoor side, and a screw 7 is formed on the outer peripheral surface of the mounting shaft 6 to screw the F-type plug. Is possible. A through hole 8 formed in the central portion of the mounting shaft 6 communicates with the inside of the housing 1.
筐体１の側辺４には、それぞれ側方へ突出する取付片９が形成され、その取付片９を介して壁面に固定される。
筐体１内には、合成樹脂でほぼ板状に形成されたセパレータ１０が取着されている。セパレータ１０には取付軸６内に向かって室内側に突出する筒状部１１が形成され、図２に示すように、その筒状部１１の先端が取付軸６の透孔８内に露出されている。筒状部１１の中心部には、出力側同軸ケーブルＣｏの芯線を挿通可能とした挿通孔１２が形成されている。
Attachment pieces 9 projecting sideways are formed on the side edges 4 of the housing 1, and are fixed to the wall surface via the attachment pieces 9.
A separator 10 made of a synthetic resin and having a substantially plate shape is attached in the housing 1. The separator 10 is formed with a cylindrical portion 11 that protrudes indoors toward the inside of the mounting shaft 6, and the tip of the cylindrical portion 11 is exposed in the through hole 8 of the mounting shaft 6 as shown in FIG. 2. ing. An insertion hole 12 through which the core wire of the output side coaxial cable Co can be inserted is formed at the center of the cylindrical portion 11.
セパレータ１０の下縁一側には、複数の係止凸部１３が室外側に向かって突出され、その係止凸部１３には端子金具１４が支持されている。端子金具１４には、下方から挿入される入力側同軸ケーブルＣｉの芯線を挟着可能とした第一のばね片１５と、室内側から挿入される出力側同軸ケーブルＣｏの芯線を挟着可能とした第二のばね片１６が形成されている。 On one side of the lower edge of the separator 10, a plurality of locking projections 13 protrude toward the outdoor side, and a terminal fitting 14 is supported by the locking projections 13. A first spring piece 15 capable of sandwiching a core wire of an input side coaxial cable Ci inserted from below and a core wire of an output side coaxial cable Co inserted from the indoor side can be sandwiched between the terminal fittings 14. The second spring piece 16 is formed.
そして、第二のばね片１６はその先端部がセパレータ１０の筒状部１１内に挿入されて、挿通孔１２に挿入される芯線を挟着可能となっている。
セパレータ１０の係止凸部１３には、合成樹脂で成形された端子ケース１７の基台部が嵌着されている。端子ケース１７の一側には直方体状の端子収容部１８が形成され、その端子収容部１８に端子金具１４の第一のばね片１５が収容されている。また、端子収容部１８の上面には、入力側同軸ケーブルＣｏの芯線を挿通可能とした挿通孔１９が形成されている。入力側同軸ケーブルＣｉを接続する端子金具１４を端子ケース１７で覆っているため、入力側同軸ケーブルＣｉの芯線と編組線の短絡を防止することができる。
The tip of the second spring piece 16 is inserted into the cylindrical portion 11 of the separator 10 so that the core wire inserted into the insertion hole 12 can be clamped.
A base portion of a terminal case 17 formed of a synthetic resin is fitted to the locking convex portion 13 of the separator 10. A rectangular parallelepiped terminal accommodating portion 18 is formed on one side of the terminal case 17, and the first spring piece 15 of the terminal fitting 14 is accommodated in the terminal accommodating portion 18. Further, an insertion hole 19 through which the core wire of the input side coaxial cable Co can be inserted is formed on the upper surface of the terminal accommodating portion 18. Since the terminal fitting 14 for connecting the input side coaxial cable Ci is covered with the terminal case 17, it is possible to prevent a short circuit between the core wire and the braided wire of the input side coaxial cable Ci.
筐体１には、筐体１内に収容されたセパレータ１０及び端子ケース１７の基台部を覆うように端子板２０が取着される。端子板２０は鉄板で形成され、四隅に形成された透孔２１で筐体１の開口部の角部に固定される。なお、端子ケース１７には端子収容部１８を端子板２０より室外側に突出させるように、端子収容部１８を挿通可能とした溝部２２が形成されている。 A terminal plate 20 is attached to the housing 1 so as to cover the separator 10 housed in the housing 1 and the base portion of the terminal case 17. The terminal board 20 is formed of an iron plate, and is fixed to the corner of the opening of the housing 1 through through holes 21 formed at the four corners. The terminal case 17 is formed with a groove portion 22 through which the terminal accommodating portion 18 can be inserted so that the terminal accommodating portion 18 protrudes outward from the terminal plate 20.
端子板２０の中央部には、端子収容部１８への芯線の挿通方向と直交する方向に延びる突条２３が形成されている。
蓋部材２は、筐体１の開口部を覆う形状に亜鉛ダイキャストで一体に形成されている。蓋部材２の周縁部は筐体１の開口部の周縁部に密接するように形成されている。蓋部材２の上縁部両側には、それぞれ側方に突出する支軸２４が形成されている。
A protrusion 23 extending in a direction orthogonal to the insertion direction of the core wire into the terminal accommodating portion 18 is formed at the center portion of the terminal plate 20.
The lid member 2 is integrally formed by zinc die casting so as to cover the opening of the housing 1. The periphery of the lid member 2 is formed so as to be in close contact with the periphery of the opening of the housing 1. On both sides of the upper edge portion of the lid member 2, support shafts 24 that protrude laterally are formed.
筐体１の側辺４には、上辺３の両端部近傍に支軸２４を保持可能とした支持溝２５が形成されている。そして、蓋部材２は支軸２４が支持溝２５に保持された状態では、支軸２４を回動支点として筐体１に回動可能に支持されている。 On the side 4 of the housing 1, support grooves 25 that can hold the support shaft 24 are formed in the vicinity of both ends of the upper side 3. The lid member 2 is rotatably supported by the housing 1 with the support shaft 24 as a rotation fulcrum in a state where the support shaft 24 is held in the support groove 25.
図１に示すように、支持溝２５は、支軸２４を回動可能に支持する溝部と、その溝部と連通し、溝部の幅及び支軸２４の直径より小さい幅の開口部を有する。開口部の幅が溝部及び支軸２４の直径より小さいため、支軸２４の支持溝２５の溝部からの脱落を防止することができる。また、支持溝２５の溝部と開口部の空間が、支軸２４の挿入により埋められるため、テレビコンセントの電磁シールド性を向上させることができる。なお、支持溝２５の形状は上記形状に限定されるものではない。 As shown in FIG. 1, the support groove 25 includes a groove portion that rotatably supports the support shaft 24, and an opening portion that communicates with the groove portion and has a width smaller than the width of the groove portion and the diameter of the support shaft 24. Since the width of the opening is smaller than the diameter of the groove and the support shaft 24, the support shaft 25 can be prevented from falling off from the groove. Further, since the space between the groove portion and the opening portion of the support groove 25 is filled by the insertion of the support shaft 24, the electromagnetic shielding property of the television outlet can be improved. The shape of the support groove 25 is not limited to the above shape.
蓋部材２の下縁には、端子収容部１８の挿通孔１９に連通する位置に保持凹部２６が開口されている。保持凹部２６は、蓋部材２に湾曲部２６ａを形成することにより断面蒲鉾状（略半円状）に形成されている。 A holding recess 26 is opened at a lower edge of the lid member 2 at a position communicating with the insertion hole 19 of the terminal accommodating portion 18. The holding recess 26 is formed in a bowl shape (substantially semicircular shape) by forming a curved portion 26 a in the lid member 2.
図２及び図５に示すように、保持凹部２６の開口部近傍において保持凹部２６に対向する湾曲部２６ａの裏面には、抜け止め突起３４が形成されている。保持凹部２６の開口部近傍に抜け止め突起３４を設けることで、入力側同軸ケーブルＣｉがたとえば引っ張られたときに、保持凹部２６の開口部からの抜けを抑制することができる。 As shown in FIGS. 2 and 5, a retaining protrusion 34 is formed on the back surface of the curved portion 26 a facing the holding recess 26 in the vicinity of the opening of the holding recess 26. By providing the retaining protrusion 34 in the vicinity of the opening of the holding recess 26, when the input-side coaxial cable Ci is pulled, for example, it is possible to prevent the retaining recess 26 from coming off from the opening.
そして、蓋部材２を開放した状態で入力側同軸ケーブルＣｉの芯線を端子収容部１８の挿通孔１９に挿通し、この状態で蓋部材２を回動して閉じると、入力側同軸ケーブルＣｉが保持凹部２６内で蓋部材２と端子板２０及び筐体１の開口縁との間で挟着保持されるようになっている。 Then, when the core wire of the input side coaxial cable Ci is inserted into the insertion hole 19 of the terminal accommodating portion 18 with the lid member 2 opened, and the lid member 2 is rotated and closed in this state, the input side coaxial cable Ci is In the holding recess 26, the lid member 2 is sandwiched and held between the terminal plate 20 and the opening edge of the housing 1.
蓋部材２の中央部には、ネジ２７を挿通可能とした透孔２８が形成されている。また、端子板２０には透孔２８に連通する位置にネジ孔２９が設けられている。そして、蓋部材２を閉じた状態でネジ２７を透孔２８からネジ孔２９に螺入すると、蓋部材２が端子板２０に固定されるとともに、常には丸軸状の入力側同軸ケーブルＣｉが保持凹部２６内で押し潰されて、保持凹部２６がほぼ封止されるようになっている。 A through hole 28 through which a screw 27 can be inserted is formed at the center of the lid member 2. The terminal plate 20 is provided with a screw hole 29 at a position communicating with the through hole 28. When the screw 27 is screwed into the screw hole 29 from the through hole 28 with the lid member 2 closed, the lid member 2 is fixed to the terminal plate 20 and the input shaft coaxial cable Ci having a round shaft shape is always connected. The holding recess 26 is almost sealed by being crushed in the holding recess 26.
図５に示すように、蓋部材２の上縁には、等間隔に複数の突起３０が形成されている。そして、図７に示すように、蓋部材２を閉じた状態では蓋部材２の上縁と筐体１の上辺３との間の間隙が突起３０で等間隔に塞がれるようになっている。 As shown in FIG. 5, a plurality of protrusions 30 are formed at equal intervals on the upper edge of the lid member 2. As shown in FIG. 7, when the lid member 2 is closed, the gap between the upper edge of the lid member 2 and the upper side 3 of the housing 1 is closed at equal intervals by the protrusions 30. .
このようにして、突起３０で間隙を塞ぐと、突起３０の間隔が波長の１／１０〜１／２０となる周波数またはそれより低い周波数の電波、すなわち入力側同軸ケーブルＣｉを介して伝送されるテレビ受信信号に対してノイズを発生させ得る電磁波に対するシールド効果が得られる。また、突起３０を設けることで蓋部材２の上縁を筐体１の上辺に接触させて、蓋部材２を安定して保持することができる。 In this way, when the gap is closed by the protrusion 30, the distance between the protrusions 30 is transmitted through a radio wave having a frequency that is 1/10 to 1/20 of the wavelength or lower, that is, via the input side coaxial cable Ci. A shielding effect against electromagnetic waves that can generate noise with respect to a television reception signal is obtained. Further, by providing the protrusions 30, the upper edge of the lid member 2 can be brought into contact with the upper side of the housing 1, so that the lid member 2 can be stably held.
筐体１の室内側の側面には、合成樹脂で四角箱状に成形された端子カバー３１が取着される。端子カバー３１の中央部には、取付軸６を挿通して室内側に露出させるための透孔３２が設けられ、室内側に向かう正面において透孔３２の周囲には取付軸６に室内側から出力側同軸ケーブルＣｏのＦ型接栓Ｆを接続するための凹部３３が形成されている。 A terminal cover 31 formed of a synthetic resin in a square box shape is attached to the side surface on the indoor side of the housing 1. A through hole 32 is provided in the center of the terminal cover 31 so as to be inserted through the mounting shaft 6 and exposed to the indoor side. Around the through hole 32 on the front side facing the indoor side, the mounting shaft 6 extends from the indoor side. A recess 33 for connecting the F-type plug F of the output side coaxial cable Co is formed.
端子カバー３１の左右方向両側面には、先端部が楔状に形成された係止片３５が形成され、その係止片３５を筐体１の取付片９に形成された取付溝３６に係合させることにより、端子カバー３１が筐体１に取着されている。 Locking pieces 35 whose tip portions are formed in a wedge shape are formed on both side surfaces of the terminal cover 31 in the left-right direction, and the locking pieces 35 are engaged with mounting grooves 36 formed in the mounting pieces 9 of the housing 1. By doing so, the terminal cover 31 is attached to the housing 1.
そして、このように構成されたテレビコンセントがブラケットを介して壁面に固定され、コンセントカバーにより端子カバー３１の正面及び取付軸６のみが壁面に露出される。
次に、上記のように構成されたテレビコンセントの作用を説明する。
The television outlet configured as described above is fixed to the wall surface via the bracket, and only the front surface of the terminal cover 31 and the mounting shaft 6 are exposed to the wall surface by the outlet cover.
Next, the operation of the television outlet configured as described above will be described.
上記のテレビコンセントを壁面に設置する際には、図６に示すように、まず蓋部材２を開けた状態で、アンテナから受信信号が供給される入力側同軸ケーブルＣｉの芯線を端子収容部１８の挿通孔１９に挿通して端子金具１４の第一のばね片１５に挟着させる。 When the TV outlet is installed on the wall surface, as shown in FIG. 6, the core wire of the input-side coaxial cable Ci to which the reception signal is supplied from the antenna is first connected with the terminal member 18 with the lid member 2 opened. Is inserted into the insertion hole 19 and is clamped to the first spring piece 15 of the terminal fitting 14.
そして、蓋部材２を閉じてネジ２７を締め込むと、蓋部材２が筐体１に固定されるとともに、入力側同軸ケーブルＣｉが保持凹部２６内で径方向に押圧されて変形する。この結果、保持凹部２６が入力側同軸ケーブルＣｉで封止される。 When the lid member 2 is closed and the screw 27 is tightened, the lid member 2 is fixed to the housing 1 and the input side coaxial cable Ci is pressed and deformed in the holding recess 26 in the radial direction. As a result, the holding recess 26 is sealed with the input side coaxial cable Ci.
この状態で、テレビコンセントを壁面に設置し、室内に露出される取付軸６に入力側同軸ケーブルＣｏのＦ型接栓Ｆを接続するとともに芯線を挿通孔１２に挿通して端子金具１４の第二のばね片１６に挟着させる。すると、入力側同軸ケーブルＣｉの芯線と出力側同軸ケーブルＣｏの芯線が端子金具１４を介して接続され、アンテナからテレビ受像機にアンテナ受信信号が供給される状態となる。 In this state, the TV outlet is installed on the wall surface, the F-type plug F of the input side coaxial cable Co is connected to the mounting shaft 6 exposed indoors, and the core wire is inserted into the insertion hole 12 and the terminal fitting 14 is The second spring piece 16 is clamped. Then, the core wire of the input side coaxial cable Ci and the core wire of the output side coaxial cable Co are connected via the terminal fitting 14, and the antenna reception signal is supplied from the antenna to the television receiver.
上記のようなテレビコンセントでは、次に示す効果を得ることができる。
（１）亜鉛ダイキャストで一体に成形した蓋部材２で筐体１の開口部を覆うようにしたので、筐体１内で接続される入力側同軸ケーブルＣｉを筐体１と蓋部材２で覆うことができる。従って、電磁シールド性を向上させて、テレビ受信出力へのノイズの混入を抑制することができる。
With the television outlet as described above, the following effects can be obtained.
(1) Since the opening of the housing 1 is covered with the lid member 2 formed integrally by zinc die casting, the input side coaxial cable Ci connected in the housing 1 is connected by the housing 1 and the lid member 2.

（３）入力側同軸ケーブルＣｉの芯線を端子ケース１７の挿通孔１９に挿通し、蓋部材２を閉じてネジ２７で筐体１に固定すれば、入力側同軸ケーブルＣｉのテレビコンセントへの接続作業が終了するため、入力側同軸ケーブルＣｉの接続作業に要する工数を削減することができる。すなわち、施工性がよく、外来ノイズに対するシールド性も確保することができる。 (3) When the core wire of the input side coaxial cable Ci is inserted into the insertion hole 19 of the terminal case 17 and the lid member 2 is closed and fixed to the housing 1 with the screw 27, the input side coaxial cable Ci is connected to the TV outlet. Since the work is completed, the man-hour required for the connection work of the input side coaxial cable Ci can be reduced. That is, the workability is good and the shielding property against external noise can be secured.
（４）筐体１を亜鉛ダイキャストで一体成型したので、透孔を設けることなく箱状の筐体を形成することができる。従って、筐体１のシールド性を向上させることができる。
（５）蓋部材２を筐体１の開口部に開閉可能に支持したので、蓋部材２を開けば入力側同軸ケーブルＣｉの芯線を端子ケース１７の挿通孔１９に容易に挿通することができる。
(4) Since the housing 1 is integrally formed by zinc die casting, a box-shaped housing can be formed without providing a through hole. Therefore, the shielding property of the housing 1 can be improved.
(5) Since the lid member 2 is supported by the opening of the housing 1 so as to be opened and closed, the core wire of the input side coaxial cable Ci can be easily inserted into the insertion hole 19 of the terminal case 17 by opening the lid member 2. .
（６）入力側同軸ケーブルＣｉの芯線を挿通孔１９に挿通した後、蓋部材２を閉じると、蓋部材２の上縁と筐体１の開口縁との間の隙間が複数の突起３０で等間隔に塞がれる。従って、蓋部材２の上縁と筐体１の開口縁との間の隙間による電磁シールド性の低下を抑制することができる。 (6) When the core member of the input side coaxial cable Ci is inserted into the insertion hole 19 and then the lid member 2 is closed, the gaps between the upper edge of the lid member 2 and the opening edge of the housing 1 are formed by the plurality of protrusions 30. Closed at equal intervals. Accordingly, it is possible to suppress a decrease in electromagnetic shielding properties due to a gap between the upper edge of the lid member 2 and the opening edge of the housing 1.
（７）蓋部材２の湾曲部２６ａに設けた抜け止め突起３４を入力側同軸ケーブルＣｉに係合させることにより、保持凹部２６からの入力側同軸ケーブルＣｉの抜けを抑制することができる。 (7) By engaging the retaining protrusion 34 provided on the curved portion 26 a of the lid member 2 with the input-side coaxial cable Ci, the input-side coaxial cable Ci can be prevented from coming off from the holding recess 26.
（８）筐体１に出力側同軸ケーブルＣｏのＦ型接栓Ｆを接続可能とした取付軸６を一体に形成したので、シールド性を向上させることができる。
上記実施形態は、以下のように変更してもよい。
