Description

本考案の軌道短絡器は、鉄道の踏切の機能を働かせるために構成している軌道回路のみを短絡させる装置であり、列車検知の軌道回路とは別に設けられた踏切制御子用の周波数のみ通し、試験を可能とする軌道短絡器及び軌道短絡器の収納ケースに関するものである。 The track short circuit device of the present invention is a device that short-circuits only the track circuit configured to operate the railroad crossing function, and passes only the frequency for the crossing controller provided separately from the track circuit for train detection. The present invention relates to an orbital short circuit enabling a test and a storage case for the orbital short circuit.

踏切の踏切制御子の周波数ごとに短絡試験を行うことができる軌道短絡器がある。 There is a track short circuit that can perform a short circuit test for each frequency of the level crossing controller.

図９〜図１１は、従来の踏切制御子の短絡試験用の軌道短絡器（踏切制御子Ｈ形用）１を示す。 9 to 11 show a conventional orbital short-circuit (for a crossing controller H type) 1 for a short circuit test of a crossing controller.

２は、上記軌道短絡器１の短絡器本体を示し、該短絡器本体２は、例えば、直方体状に形成され、該短絡器本体２内には、複数の所望の周波数で、それぞれ一対の一方及び他方のレール（軌条）３ａ、３ｂを短絡する短絡試験回路（図示せず）が設けられる。 2 indicates a short circuit body of the track short circuit 1, and the short circuit body 2 is formed in a rectangular parallelepiped shape, for example, and a plurality of desired frequencies are included in the short circuit body 2 respectively. And the short circuit test circuit (not shown) which short-circuits the other rail (rail) 3a, 3b is provided.

また、上記短絡器本体２の上面には、上記短絡試験回路に設けられた、上記一方のレール３ａ側に接続される、短絡試験される所望の周波数毎に設けられた複数の端子部４と、上記他方のレール３ｂ側に接続される、一つの共通端子部５とが設けられている。 Further, on the upper surface of the short-circuit main body 2, a plurality of terminal portions 4 provided for each desired frequency to be short-circuited connected to the one rail 3a side provided in the short-circuit test circuit, and A common terminal portion 5 connected to the other rail 3b side is provided.

６は、基部が、上記複数の端子部４のうち、いずれか１つに接続される一方の短絡コード、７は、該一方の短絡コード６の先端部に設けられた、上記一方のレール３ａに接触して接続される一方の接触部を示す。 6 is one short-circuit cord whose base is connected to any one of the plurality of terminal portions 4, and 7 is the one rail 3 a provided at the tip of the one short-circuit cord 6. The one contact part connected in contact with is shown.

また、８は、基部が、上記共通端子部５に接続される他方の短絡コード、９は、該他方の短絡コード８の先端部に設けられた、他方のレール３ｂに接触して接続される他方の接触部を示す。 Reference numeral 8 denotes the other short-circuit cord whose base is connected to the common terminal portion 5, and 9 is connected to the other rail 3 b provided at the tip of the other short-circuit cord 8. The other contact part is shown.

なお、上記一方及び他方の接触部７、９は、それぞれ、例えば、円柱状の導電性のある磁石により形成し、該各接触部７、９の上端面に、上記一方又は他方の短絡コード６、８の先端部が接続され、下端面が、上記一方又は他方のレール３ａ、３ｂに磁力により接触して接続されるように構成される。 The one and other contact portions 7 and 9 are each formed of, for example, a cylindrical conductive magnet, and the one or the other short-circuit cord 6 is formed on the upper end surface of each contact portion 7 or 9. , 8 are connected, and the lower end surface is configured to contact and be connected to the one or other rail 3a, 3b by a magnetic force.

上記従来の軌道短絡器１においては、上記一方の短絡コード６の基部を、試験すべき周波数の端子部４に接続し、また、上記他方の短絡コード８の基部を、上記共通端子部５に接続し、そして、上記一方の短絡コード６の一方の接触部７を、上記一方のレール３ａに磁力により接続し、また、上記他方の短絡コード８の接触部９を、上記他方のレール３ｂに磁力により接続させて、上記試験すべき所望の周波数における短絡試験を行うようにする。 In the conventional track short circuit 1, the base portion of the one short-circuit cord 6 is connected to the terminal portion 4 of the frequency to be tested, and the base portion of the other short-circuit cord 8 is connected to the common terminal portion 5. Then, one contact portion 7 of the one short-circuit cord 6 is connected to the one rail 3a by magnetic force, and the contact portion 9 of the other short-circuit cord 8 is connected to the other rail 3b. The connection is made by magnetic force so that the short-circuit test at the desired frequency to be tested is performed.

そして、他の周波数の短絡試験を行う場合には、一旦、上記一方及び他方の接触部７、９を上記一方及び他方のレール３ａ、３ｂから取り外してから、上記一方の短絡コード６の基部を、上記端子部４から取り外し、他の周波数の端子部４に接続し、そして、上記一方の短絡コード６の一方の接触部７を、上記一方のレール３ａに接続し、また、上記他方の短絡コード８の接触部９を、上記他方のレール３ｂに接続させて、上記同様に、上記他の周波数における短絡試験を行っていた。 When performing a short-circuit test at another frequency, the one and the other contact portions 7, 9 are once removed from the one and the other rails 3a, 3b, and then the base of the one short-circuit cord 6 is removed. , Removed from the terminal part 4, connected to the terminal part 4 of another frequency, and one contact part 7 of the one short-circuit cord 6 is connected to the one rail 3a, and the other short-circuit The contact portion 9 of the cord 8 is connected to the other rail 3b, and the short-circuit test at the other frequencies is performed in the same manner as described above.

しかしながら、上記従来の軌道短絡器の短絡コード６、８の基部は、先開形圧着端子により形成され、上記端子部４、５に、それぞれネジの締付による圧着により接続して固定されるため、短絡試験実施中の運搬中などに端子弛緩が生じ、短絡試験時に短絡不良となる場合があり、その都度、端子の接続確認が必要であった。 However, the bases of the short-circuit cords 6 and 8 of the conventional track short-circuit are formed by tip-open crimp terminals, and are connected and fixed to the terminal sections 4 and 5 by crimping with screws. In some cases, loosening of the terminals occurred during transportation during the short circuit test, resulting in a short circuit failure during the short circuit test, and it was necessary to check the connection of the terminals each time.

同様に、上記短絡コード６、８の先端部も、先開形圧着端子により形成され、上記接触部７、９に、それぞれネジの締付による圧着により接続して固定されるため、短絡試験実施中の運搬中などに、端子弛緩が生じて、接触不良となる場合があった。 Similarly, the tip portions of the short-circuit cords 6 and 8 are also formed by tip-open crimp terminals, and are connected and fixed to the contact portions 7 and 9 by crimping by screw tightening. In some cases, loosening of the terminals occurred during transportation, resulting in poor contact.

また、短絡試験すべき周波数毎に、一方の短絡コード６の基部を、所望の端子部４毎に付け替える作業が必要であり、手間がかかっていた。 Moreover, the operation | work which replaces | exchanges the base part of one short circuit cord 6 for every desired terminal part 4 for every frequency which should carry out a short circuit test was required, and it took the effort.

また、上記接触部７、９は、例えば、直径４０ｍｍ、高さが６０ｍｍほどの円柱状に形成され、指でつまんで取り扱われるもので、取り扱いづらかった。 Further, the contact portions 7 and 9 are formed in a columnar shape having a diameter of 40 mm and a height of about 60 mm, for example, and are handled by being pinched with fingers, which is difficult to handle.

また、従来の上記軌道短絡器は、収納ケースから取り出さなければ、使用できず、雨天時には、使用できなかった。 Moreover, the conventional orbital short circuit device cannot be used unless it is taken out of the storage case, and cannot be used in rainy weather.

本考案は、上記の欠点を除くようにしたものである。 The present invention eliminates the above-mentioned drawbacks.
