Description

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 or the like and 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 a wall surface in the room, and the antenna reception signal is supplied from the TV outlet to a television receiver via an output side coaxial cable. It

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, along with the ultra-high definition of television broadcasting, the IF frequency band of a reception signal supplied to a 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 having a configuration in which an input side coaxial cable to which a reception signal is supplied from a television antenna is connected without using an F-type plug. In this television outlet, a housing for accommodating a connecting fitting for electrically connecting the input side coaxial cable and the output side coaxial cable is formed into 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, since the core wire of the input side coaxial cable and the terminal metal fittings electrically connected to the core wire are not electromagnetically shielded, interference with electromagnetic waves of other communication services may occur. It is easily 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 by using the F-type plug, the shielding property is improved, but the case and the F-type plug are integrally formed by die casting, which requires labor for processing. There's a problem. In addition, the work of screwing the F-type plug into 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 thereof is to provide a television outlet which has good workability and can also secure a shield property against external noise.

上記課題を解決するテレビコンセントは、出力側同軸ケーブルのＦ型接栓が接続される取付軸と、前記取付軸が設けられた第１面の両側に形成され、それぞれ側方へ突出する取付片と、を有する金属製の筐体と、前記筐体に回動可能に支持される金属製の蓋部材と、を備え、前記筐体は、前記取付片にて屋内の壁面に固定され、前記取付軸および取付片は、金属で一体に形成される。 A television outlet that solves the above-mentioned problems is a mounting shaft to which an F-type connector of an output side coaxial cable is connected and a mounting piece that is formed on both sides of a first surface on which the mounting shaft is provided and that projects laterally. And a metal lid member rotatably supported by the housing, the housing being fixed to an indoor wall surface by the mounting piece, The mounting shaft and the mounting piece are integrally formed of metal.

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, the workability and the shielding property 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。 An embodiment of a television outlet will be described below with reference to the drawings. The television 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. To be

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. When the television outlet is attached to the wall surface, the casing 1 is attached so as to open toward the outside of the room. The upper side 3 of the housing 1 and the upper portions of the side edges 4 connected to both sides of the upper side 3 extend 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 is projected on the other side surface of the housing 1, that is, a side surface facing the indoor side, and a screw 7 is engraved on the outer peripheral surface of the mounting shaft 6 to screw the F-type plug. Is possible. The 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。 Mounting pieces 9 projecting laterally are formed on the side edges 4 of the housing 1, and are fixed to the wall surface via the mounting pieces 9.
Inside the housing 1, a separator 10 made of synthetic resin and formed in a substantially plate shape is attached. The separator 10 is formed with a tubular portion 11 that protrudes toward the inside of the mounting shaft 6 toward the inside. As shown in FIG. 2, the tip of the tubular portion 11 is exposed in the through hole 8 of the mounting shaft 6. ing. An insertion hole 12 is formed in the center of the tubular portion 11 so that the core wire of the output side coaxial cable Co can be inserted therein.

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 are projected toward the outside of the room, and the locking projections 13 support terminal fittings 14. In the terminal fitting 14, the first spring piece 15 capable of sandwiching the core wire of the input side coaxial cable Ci inserted from below and the core wire of the output side coaxial cable Co inserted from the indoor side can be sandwiched. 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 tubular portion 11 of the separator 10 so that the core wire inserted into the insertion hole 12 can be sandwiched.
The base portion of the terminal case 17, which is molded of synthetic resin, is fitted to the locking protrusion 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 is formed on the upper surface of the terminal accommodating portion 18 so that the core wire of the input side coaxial cable Co can be inserted therethrough. 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。 The terminal plate 20 is attached to the housing 1 so as to cover the separator 10 housed in the housing 1 and the base of the terminal case 17. The terminal plate 20 is formed of an iron plate, and is fixed to the corners of the opening of the housing 1 by the through holes 21 formed at the four corners. In addition, 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 projects 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 ridge 23 extending in a direction orthogonal to the insertion direction of the core wire into the terminal accommodating portion 18 is formed in the center of the terminal plate 20.
The lid member 2 is integrally formed by zinc die casting in a shape that covers the opening of the housing 1. The peripheral edge of the lid member 2 is formed so as to be in close contact with the peripheral edge of the opening of the housing 1. Support shafts 24 are formed on both sides of the upper edge of the lid member 2 so as to project laterally.

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。 A support groove 25 capable of holding a support shaft 24 is formed on the side edge 4 of the housing 1 near both ends of the upper edge 3. Further, the lid member 2 is rotatably supported by the housing 1 with the support shaft 24 as a rotation fulcrum when 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 has a groove portion rotatably supporting the support shaft 24, and an opening communicating with the groove portion and having a width smaller than the width of the groove 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, it is possible to prevent the support shaft 24 from coming off from the groove of the support groove 25. Further, the space between the groove and the opening of the support groove 25 is filled by inserting the support shaft 24, so that the electromagnetic shielding property of the TV 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。 At the lower edge of the lid member 2, a holding recess 26 is opened at a position communicating with the insertion hole 19 of the terminal accommodating portion 18. The holding recess 26 is formed into a semi-cylindrical shape (substantially semicircular) by forming a curved portion 26a on 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 near the opening of the holding recess 26. By providing the retaining projection 34 near the opening of the holding recess 26, it is possible to prevent the retaining recess 26 from coming off the opening when the input-side coaxial cable Ci is pulled, for example.

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 lid member 2 is opened, the core wire of the input side coaxial cable Ci is inserted into the insertion hole 19 of the terminal accommodating portion 18, and when 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 and the terminal plate 20 and the opening edge of the housing 1 are sandwiched and held.

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 into which a screw 27 can be inserted is formed in the central portion of the lid member 2. Further, the terminal plate 20 is provided with a screw hole 29 at a position communicating with the through hole 28. Then, 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 round shaft-shaped input side coaxial cable Ci is always provided. The holding recess 26 is crushed so that the holding recess 26 is substantially sealed.

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 on the upper edge of the lid member 2 at equal intervals. Then, as shown in FIG. 7, when the lid member 2 is closed, the gaps between the upper edge of the lid member 2 and the upper side 3 of the housing 1 are closed by the protrusions 30 at equal intervals. ..

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。 When the gap is closed by the protrusions 30 in this manner, radio waves having a frequency at which the intervals between the protrusions 30 are 1/10 to 1/20 of the wavelength or lower frequencies, that is, transmitted through the input side coaxial cable Ci. It is possible to obtain a shielding effect against electromagnetic waves that may generate noise with respect to television reception signals. Further, by providing the projection 30, the upper edge of the lid member 2 can be brought into contact with the upper side of the housing 1, and 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 rectangular box shape is attached to the side surface of the housing 1 on the indoor side. A through hole 32 is provided in the center of the terminal cover 31 for inserting the mounting shaft 6 and exposing the mounting shaft 6 to 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。 Wedge-shaped locking pieces 35 are formed on the left and right side surfaces of the terminal cover 31, and the locking pieces 35 are engaged with the mounting grooves 36 formed in the mounting piece 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 thus configured is fixed to the wall surface via the bracket, and the outlet cover exposes only the front surface of the terminal cover 31 and the mounting shaft 6 to the wall surface. 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 above TV outlet is installed on the wall surface, as shown in FIG. 6, first, with the lid member 2 open, the core wire of the input side coaxial cable Ci to which the reception signal is supplied from the antenna is connected to the terminal accommodating portion 18. The first spring piece 15 of the terminal fitting 14 is inserted through the insertion hole 19 of FIG.

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 in the holding recess 26 in the radial direction to be deformed. 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, a TV outlet is installed on the wall surface, the F-type connector F of the input side coaxial cable Co is connected to the mounting shaft 6 exposed in the room, and the core wire is inserted into the insertion hole 12 to connect the terminal metal fitting 14 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 metal 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 above TV outlet, the following effects can be obtained.
(1) Since the opening portion of the housing 1 is covered with the lid member 2 integrally formed by zinc die casting, the input side coaxial cable Ci connected in the housing 1 is connected between the housing 1 and the lid member 2. Can be covered. Therefore, it is possible to improve the electromagnetic shielding property and suppress the mixing of noise into the television reception output.

（２）入力側同軸ケーブルＣｉを蓋部材２の湾曲部２６ａと筐体１の開口縁及び端子板２０との間で押圧して保持凹部２６をほぼ封止する状態とすることができる。従って、Ｆ型接栓Ｆを使用することなく、筐体１内で接続される入力側同軸ケーブルＣｉに対する電磁シールド性を向上させることができる。 (2) The input side coaxial cable Ci can be pressed between the curved portion 26a of the lid member 2 and the opening edge of the housing 1 and the terminal plate 20 to bring the holding recess 26 into a substantially sealed state. Therefore, it is possible to improve the electromagnetic shielding property for the input side coaxial cable Ci connected in the housing 1 without using the F-type plug F.

（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) If the core wire of the input side coaxial cable Ci is inserted into the insertion hole 19 of the terminal case 17, 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, it is possible to reduce the man-hour required for the work of connecting the input side coaxial cable Ci. 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 molded by zinc die casting, a box-shaped housing can be formed without providing through holes. Therefore, the shield property of the housing 1 can be improved.
(5) Since the lid member 2 is openably and closably supported in the opening of the housing 1, 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 lid member 2 is closed after the core wire of the input side coaxial cable Ci is inserted into the insertion hole 19, the gap between the upper edge of the lid member 2 and the opening edge of the housing 1 is formed by the plurality of protrusions 30. Closed at equal intervals. Therefore, it is possible to suppress the deterioration of the electromagnetic shielding property due to the gap between the upper edge of the lid member 2 and the opening edge of the housing 1.
