【発明の属する技術分野】
本発明は火災報知設備や防犯設備等の受信機と端末機器との間に設けられる中継器に関し、より詳細には中継器盤に複数個まとめて収納され相互に連結される中継器に関する。
【0002】
【従来の技術】
例えば特許文献1に示すような火災報知設備や、その他防犯設備等では通常、端末機器と受信機との間に、相互間の信号のやりとりを中継する中継器が設置される。このような中継器は通常、中継器盤に複数個まとめて収納される。ここで、隣接する中継器同士は信号線Sとコモン線SCが連結され、信号を相互に授受している。従来、信号線S、コモン線SCを連結するには、リード線の両端をそれぞれ隣接する中継器の端子台の端子穴に挿入して渡り配線を行っている。
しかし、中継器盤に収納される中継器の数は数十個にも及ぶ場合があり、それぞれの中継器を、リード線の両端部を逐次中継器の端子穴に挿入して連結していたのでは、作業が繁雑であり、現場における取付工数、取付時間の増加を招く。
【0003】
【特許文献1】
特開平10−143776(図1)
【0004】
そこで本発明者は、中継器内の基板に信号線S、コモン線SCとそれぞれ導通する結線部を設け、この結線部にリード線の一端を半田付け等で直結した中継器を発明した。このような構成とすることによって、中継器同士を連結する際に、リード線の一端を端子台の端子穴に挿入する作業が不要となり、中継器の取付けに必要な作業を大幅に減少させることができる。
【0005】
【発明が解決しようとする課題】
ところで、基板を上述したような構成とした場合には、リード線をケース本体の外部に引出す必要がある。しかし従来のケース本体は、下方開口状で底深に形成され端子台を上面に露出させると共に、その下部に中継器盤に固定される底浅の取付台を取付ける構成となっている。このような構成のケース本体は下方開口状で底深に形成されているため、基板に接続されたリード線を上方へ引出すことが難しく、中継器の組立作業性が悪くなってしまう恐れがある。
【0006】
本発明は以上の問題点を鑑みてなされたものであり、組立作業及び隣接する中継器との連結作業が容易な中継器を提供することを目的とする。
【0007】
【課題を解決するための手段】
上記課題を解決するため本発明は、中継器盤内に複数収められるケース本体と、該ケース本体に収納した基板からなると共に、該基板はリード線接続用の端子台を備えてなる中継器において、上記ケース本体は上方開口状で底深に形成されてなると共に、その上部に上記基板の端子台を露出させる蓋体を着脱自在に取付けてなり、上記基板にはリード線の一端が直結され、上記蓋体は上記端子台を露出させる端子開口部と、該端子開口部と連続状に形成される線開口部を有し、該線開口部から上記リード線を引出してなることを特徴として構成されている。
【0010】
【発明の実施の形態】
以下、本発明の実施の形態について、図面を参照しつつ詳細に説明する。図1は本発明の実施形態における中継器の分解図、図2は本発明の実施形態における中継器の側方斜視図、図3は本発明の実施形態における蓋体の底面斜視図、図4は本発明の実施形態における中継器をリード線によって連結した状態の上面模式図である。なお、本実施形態において、上下左右は図1に示す向きとする。
本実施形態における中継器1は、中継器盤(図示せず)に複数個並べて収納されるものであり、図1に示すように、中継器盤に収納されるケース本体20、及びこのケース本体20に収納され、端末機器と受信機との間の信号を処理するための回路が実装された基板10からなる。ケース本体20には基板10を収納した状態で上部に蓋体30が取付けられる。
【0011】
ケース本体20に内装される基板10は略長方形状であり、その上端近傍に端子台11が備え付けられている。この端子台11は、基板10の回路内の信号線Sと導通し、受信機からの信号線や隣の中継器1のリード線12aを挿入するS端子穴11a、基板10の回路内のコモン線SCと導通し、受信機からのコモン線やとなりの中継器1のリード線12bを挿入するSC端子穴11b、及びその他受信機、端末機器等の外部からのリード線を挿入する外部端子穴11c、11cを有する。
【0012】
また同じく基板10の上端近傍には、基板10の回路内の信号線S、コモン線SCとそれぞれ導通する結線部13a、13b、及びこの結線部13a、13bにそれぞれの一端が直結される2本のリード線12a、12bを有している。即ち、従来、S端子穴11aあるいはSC端子穴11bに挿入していたリード線12a、12bの一端を、半田付け等により直接基板10に接続する。この結線部13a、13bは、端子台11のS端子穴11a、SC端子穴11b近傍に設けられる。即ち、本実施形態においてはS端子穴11a、SC端子穴11bが右側に配置されていることから、結線部13a、13bは端子台11の右側に設けられる。また、リード線12a、12bの他端の接続部14a、14bには、S端子穴11a、SC端子穴11bの直径と略同径の棒状の差込端子15a、15bが設けられている。
ここで、基板10の形状については特に略長方形に限定されるものではなく、どのような形状でもよい。また、基板10上の端子台11や結線部13a、13bの位置も、特にこれに限定されるものではなく、基板10の回路の配置や配線等の事情により、自由に変更可能である。
【0013】
中継器1の基板10をこのような構成とすることによって、隣接する中継器1、1の信号線S、コモン線SCを連結するにあたって、リード線12a、12bの一端をS端子穴11a、SC端子穴11bに挿入する作業が不要となり、作業現場においては、図4に示すように、結線部13aに直結したリード線12aを他の中継器1のS端子穴11aに、結線部13bに直結したリード線12bを他の中継器1のSC端子穴11bにそれぞれ挿入するだけでよいので、中継器1の取付け作業が容易になると共に、必要な取付工数を大幅に減少させることができる。また、リード線12a、12bがすでに基板10に備え付けられているので、作業現場に中継器1とは別にリード線を持込む必要もなくなる。さらに、従来リード線12a、12bの一端を挿入していたS端子穴11a、SC端子穴11bが必要なくなるので、端子台11を小型にすることができ、従って中継器1を小型化することが可能となる。さらにまた、リード線12a、12bの接続部14a、14bに棒状の差込端子15a、15bを設けることにより、リード線12a、12bのS端子穴11a、SC端子穴11bへの挿入・抜出が一層容易になる。
【0014】
このような基板10を収納するケース本体20は、図1に示すように上方開口状で、上述の基板10を収納可能な幅、深さに形成され、上述の基板10が端子台11を上方にして収納される。ケース本体20がこのような構成であれば、蓋体30は底浅でよいので、基板10に直結したリード線12a、12bを、蓋体30を介して外部に引出すことが容易となり、組立作業性が向上する。
ケース本体20内部の基板10の各端部と対向する部分には、基板10の厚さと略同じ幅の溝を有するガイド部21が設けられている。このガイド部21を設けたことにより、基板10をケース本体20内に収納し易くなり中継器1の組立作業が容易となると共に、ケース本体20内における基板10の位置決めが可能となる。また、ケース本体20の上端部には、後述する蓋体30の係合部34と係合する被係合部22が形成されている。さらに、ケース本体20の下部には、中継器盤の底に設けられたレール(図示せず)が収まるレール収容部23、及び中継器盤にねじ止め固定するためのねじ孔24が設けられている。これによって、中継器1が中継器盤に収納された際の位置決め、固定がなされる。
【0015】
またケース本体20の幅狭側の側面部20aには、図2に示すように、ケース本体20の外部に引出したリード線12a、12bを保持するリード線保持部25が設けられている。このリード線保持部25は、基板10の結線部13a、13bに近い側の側面部20a、即ち本実施形態においては右側の側面部20aに設けられる。
このリード線保持部25により、中継器1を作業現場に運ぶ際に、リード線12a、12bをリード線保持部25に保持させておくことができるので、リード線12a、12bが垂れ下がって他の機器等に絡まる心配もない。また、複数の中継器1、1をリード線12a、12bによって連結する際に、最後の中継器1のリード線12a、12bは接続先がなく余ってしまうが、図4に示すように、この余ったリード線12a、12bをリード線保持部25で保持しておくことにより、短絡を防ぐことができる。このリード線保持部25は、図2に示すように、フック形状をしており、差込端子15a、15bを引っかけて保持させる。あるいはリード線保持部25を、差込端子15a、15bの直径と略同径の差込穴で構成してもよい。このような構成にすれば、差込端子15a、15bが鞘に収められたような状態になり、運送時などに差込端子15a、15bが傷つく恐れがなくなる。
【0016】
ケース本体20の上部には図1、図2に示すように、蓋体30が脱着自在に取付けられる。蓋体30のケース本体20への取付けは、係合部34をケース本体20の被係合部22に係合させることにより行う。この蓋体30はなるべく底浅であるほうが、よりリード線12a、12bを引出しやすく望ましい。
この蓋体30には、ケース本体20に基板10を納めた際に、端子台11を外部に露出させるための端子開口部31が形成されている。なお、この蓋体30の製造段階においては、端子開口部31の部分にはカバー片32が形成されている。基板10の端子台11は外部端子穴11cの数によってその大きさが異なるので、端子台11の大きさに合わせてこのカバー片32を折って取除き、必要な大きさの端子開口部31を形成する。蓋体30をこのような構成とすることにより、端子台11の外部端子穴11cの数が異なる様々な基板10に対応させることができ、端子台11の大きさに合わせた新たな蓋体30を製造する必要がなくなる。
【0017】
また蓋体30には、基板10の結線部13a、13bに対応する位置に端子開口部31と連続状に、基板10のリード線12a、12bをケース本体20の外部に引出すための線開口部33が形成されている。本実施形態においては、結線部13a、13bが端子台11の右側に設けられていることから、線開口部33も端子開口部31の右側に形成する。この線開口部33はリード線12a、12bの直径と略同幅で、かつリード線12a、12bが2本並べて収まる大きさの横断面略U字状に形成されている。なお、線開口部33については特に上記の位置、形状に限定されることなく、自由に変更可能である。
さらに図3に示すように、蓋体30底面の基板10上端角部と対向する位置には、保持部35が設けられている。この保持部35は基板10の厚さと略同幅の溝を有するように形成されており、基板10をこの保持部35にはめ込んで蓋体30側で一時的に保持することが可能となっている。
【0018】
リード線12a、12bを引出す際には、まずリード線12a、12bを線開口部33よりも開口面積の広い端子開口部31に通し、その後線開口部33側にスライドさせることによって、容易に線開口部33内にリード線12a、12bを収納することができる。さらに、そのまま基板10と蓋体30を近づけると、端子開口部31が端子台11によって塞がれ、これによって線開口部33と端子開口部31が連続している部分も端子台11に塞がれるので、リード線12a、12bを線開口部33内に閉じこめることができ、リード線12a、12bを線開口部33内に固定することができる。
また、基板10をこのまま保持部35にはめ込んで蓋体30側で保持することにより、リード線12a、12bを線開口部33内に固定しつつ、蓋体30を基板10と共にケース本体20に取付けることが可能となり、リード線12a、12bをケース本体20外部に引出した状態での中継器1の組立作業が非常に容易となる。
【0019】
なお、本実施形態においては、リード線12a、12bを基板10に半田で直接付けているが、コネクタ等を介してリード線12a、12bが基板10に付けられていても良く、予め中継器1にリード線12a、12bが取り付けられた構成であれば本発明を適用できる。また、リード線12a、12bを引出す線開口部33は、本実施形態のように端子開口部31と連通していなくても良く、蓋体30に独立した線開口部を設けても良い。
【0020】
【発明の効果】
以上本発明によれば、ケース本体は上方開口状で底深に形成されてなると共に、その上部に基板の端子台を露出させる蓋体を着脱自在に取付けてなり、基板にはリード線の一端が直結され、蓋体は線開口部を有し、該線開口部からリード線を引出してなるので、基板に直結したリード線を外部に引出すことが容易となり、また中継器同士の連結はこの引出されたリード線を隣接する中継器の端子台に接続すればよいだけなので、中継器の組立作業性、連結作業性が向上する。
【0021】
また本発明によれば、蓋体は溝状の保持部を備え、該保持部で基板を保持してリード線を線開口部内に固定してなるので、基板をケース本体に収納する際に、リード線を線開口部に固定した状態で、基板と共に蓋体をケース本体に取付けることが可能となり、リード線をケース本体外部に引出した状態での中継器の組立作業が非常に容易となる。
【0022】
また本発明によれば、ケース本体は基板のケース本体内における位置決めをする溝状のガイド部を備えるので、基板をケース本体に収納し易くなり中継器の組立作業が容易となる。また、基板のケース本体内での位置決めを行うことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a repeater provided between a receiver such as a fire alarm facility or a crime prevention facility and a terminal device, and more particularly to a repeater that is housed in a repeater panel and connected to each other.
[0002]
[Prior art]
For example, in a fire alarm facility such as that disclosed in Patent Document 1 and other crime prevention facilities, a repeater that relays the exchange of signals between the terminal device and the receiver is usually installed. Usually, a plurality of such repeaters are stored together in a repeater panel. Here, the signal line S and the common line SC are connected between adjacent repeaters, and signals are exchanged between them. Conventionally, in order to connect the signal line S and the common line SC, both ends of the lead wires are respectively inserted into the terminal holes of the terminal blocks of the adjacent repeaters to perform the crossover wiring.
However, the number of repeaters stored in the repeater panel may reach several tens, and each repeater was connected by inserting both ends of the lead wire into the terminal holes of the repeater sequentially. In this case, the work is complicated, and the installation man-hour and the installation time at the site are increased.

[0005]
[Problems to be solved by the invention]
By the way, when the substrate is configured as described above, it is necessary to draw out the lead wires to the outside of the case body. However, the conventional case main body is configured to have a bottom opening and a bottom depth so that the terminal block is exposed on the upper surface, and a shallow bottom mounting base fixed to the repeater panel is attached to the lower portion. Since the case main body having such a configuration is formed in a lower opening and deep in the bottom, it is difficult to pull out the lead wire connected to the board upward, and the assembling workability of the repeater may be deteriorated. .
[0006]
The present invention has been made in view of the above problems, and an object thereof is to provide a repeater that can be easily assembled and connected to an adjacent repeater.
[0007]

[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 is an exploded view of a repeater according to an embodiment of the present invention, FIG. 2 is a side perspective view of the repeater according to an embodiment of the present invention, and FIG. 3 is a bottom perspective view of a lid body according to the embodiment of the present invention. These are the upper surface schematic diagrams of the state which connected the repeater in embodiment of this invention with the lead wire. In the present embodiment, the top, bottom, left and right are oriented as shown in FIG.
A plurality of repeaters 1 in this embodiment are stored side by side on a repeater panel (not shown). As shown in FIG. 1, a case main body 20 accommodated in the repeater panel, and the case main body. 20, and includes a substrate 10 on which a circuit for processing a signal between the terminal device and the receiver is mounted. A lid body 30 is attached to the upper portion of the case body 20 in a state where the substrate 10 is accommodated.
[0011]
The substrate 10 housed in the case body 20 has a substantially rectangular shape, and a terminal block 11 is provided in the vicinity of the upper end thereof. The terminal block 11 is electrically connected to the signal line S in the circuit of the substrate 10, the S terminal hole 11 a for inserting the signal line from the receiver and the lead wire 12 a of the adjacent repeater 1, and the common in the circuit of the substrate 10. SC terminal hole 11b for inserting the lead wire 12b of the repeater 1 and the common line from the receiver, which is electrically connected to the line SC, and other external terminal holes for inserting other lead wires from the receiver, terminal equipment, etc. 11c, 11c.
[0012]
Similarly, in the vicinity of the upper end of the substrate 10, there are two connection portions 13a and 13b that are electrically connected to the signal line S and the common line SC in the circuit of the substrate 10, respectively, and two ends that are directly connected to the connection portions 13a and 13b. Lead wires 12a and 12b. That is, one end of the lead wires 12a and 12b, which has been conventionally inserted into the S terminal hole 11a or the SC terminal hole 11b, is directly connected to the substrate 10 by soldering or the like. The connection portions 13a and 13b are provided in the vicinity of the S terminal hole 11a and the SC terminal hole 11b of the terminal block 11. That is, in this embodiment, since the S terminal hole 11a and the SC terminal hole 11b are arranged on the right side, the connection parts 13a and 13b are provided on the right side of the terminal block 11. Further, the connecting portions 14a and 14b at the other ends of the lead wires 12a and 12b are provided with rod-like insertion terminals 15a and 15b having substantially the same diameter as the diameters of the S terminal hole 11a and the SC terminal hole 11b.
Here, the shape of the substrate 10 is not particularly limited to a substantially rectangular shape, and may be any shape. Further, the positions of the terminal block 11 and the connection portions 13a and 13b on the substrate 10 are not particularly limited to this, and can be freely changed depending on the circuit arrangement of the substrate 10 and the wiring.

By configuring the substrate 10 of the repeater 1 in such a configuration, when connecting the signal line S and the common line SC of the adjacent repeaters 1 and 1, one end of the lead wires 12 a and 12 b is connected to the S terminal hole 11 a and SC. As shown in FIG. 4, the lead wire 12a directly connected to the connection portion 13a is directly connected to the S terminal hole 11a of the other repeater 1 and to the connection portion 13b, as shown in FIG. Since it is only necessary to insert the lead wires 12b into the SC terminal holes 11b of the other repeaters 1, the attachment work of the repeaters 1 is facilitated, and the required number of attachment steps can be greatly reduced. Further, since the lead wires 12a and 12b are already provided on the substrate 10, it is not necessary to bring the lead wires separately from the repeater 1 at the work site. Further, since the S terminal hole 11a and the SC terminal hole 11b into which one end of the lead wires 12a and 12b is conventionally inserted are not necessary, the terminal block 11 can be reduced in size, and thus the repeater 1 can be reduced in size. It becomes possible. Furthermore, by providing rod-like insertion terminals 15a and 15b on the connecting portions 14a and 14b of the lead wires 12a and 12b, the lead wires 12a and 12b can be inserted into and extracted from the S terminal hole 11a and the SC terminal hole 11b. It becomes easier.

As shown in FIG. 1, the case main body 20 for storing such a substrate 10 has an upper opening shape and is formed to have a width and a depth that allow the above-described substrate 10 to be stored. And stored. If the case main body 20 has such a structure, the lid 30 may be shallow, so that the lead wires 12a and 12b directly connected to the substrate 10 can be easily pulled out to the outside through the lid 30, and assembly work can be performed. Improves.
A guide portion 21 having a groove having a width substantially the same as the thickness of the substrate 10 is provided at a portion facing each end portion of the substrate 10 inside the case body 20. By providing the guide portion 21, the board 10 can be easily accommodated in the case body 20, the assembling work of the repeater 1 is facilitated, and the board 10 can be positioned in the case body 20. Further, an engaged portion 22 that engages with an engaging portion 34 of a lid 30 to be described later is formed at the upper end portion of the case body 20. Furthermore, a rail housing portion 23 for receiving a rail (not shown) provided on the bottom of the relay panel and a screw hole 24 for screwing and fixing to the relay panel are provided at the lower part of the case body 20. Yes. Thereby, positioning and fixing when the repeater 1 is stored in the repeater panel are performed.
[0015]
Further, as shown in FIG. 2, a lead wire holding portion 25 that holds the lead wires 12 a and 12 b drawn to the outside of the case main body 20 is provided on the narrow side surface portion 20 a of the case main body 20. The lead wire holding portion 25 is provided on the side surface portion 20a on the side close to the connection portions 13a and 13b of the substrate 10, that is, the right side surface portion 20a in this embodiment.
The lead wire holding portion 25 can hold the lead wires 12a and 12b in the lead wire holding portion 25 when the repeater 1 is carried to the work site, so that the lead wires 12a and 12b hang down and other There is no worry about getting involved in equipment. In addition, when connecting a plurality of repeaters 1, 1 by lead wires 12a, 12b, the lead wires 12a, 12b of the last repeater 1 have no connection destination, but as shown in FIG. By holding the remaining lead wires 12a and 12b with the lead wire holding portion 25, a short circuit can be prevented. As shown in FIG. 2, the lead wire holding portion 25 has a hook shape and hooks and holds the plug-in terminals 15a and 15b. Or you may comprise the lead wire holding | maintenance part 25 by the insertion hole of substantially the same diameter as the diameter of the insertion terminals 15a and 15b. With such a configuration, the insertion terminals 15a and 15b are in a state of being accommodated in the sheath, and there is no possibility that the insertion terminals 15a and 15b are damaged during transportation.
[0016]
As shown in FIGS. 1 and 2, a lid 30 is detachably attached to the upper portion of the case body 20. The lid 30 is attached to the case main body 20 by engaging the engaging portion 34 with the engaged portion 22 of the case main body 20. It is desirable that the lid 30 be as shallow as possible because the lead wires 12a and 12b can be more easily pulled out.
The lid 30 is formed with a terminal opening 31 for exposing the terminal block 11 to the outside when the substrate 10 is placed in the case body 20. Note that a cover piece 32 is formed in the terminal opening 31 at the stage of manufacturing the lid 30. Since the size of the terminal block 11 of the substrate 10 varies depending on the number of external terminal holes 11c, the cover piece 32 is folded and removed in accordance with the size of the terminal block 11, and the terminal opening 31 having a required size is removed. Form. By adopting such a configuration of the lid body 30, it is possible to correspond to various substrates 10 having different numbers of external terminal holes 11 c of the terminal block 11, and a new lid body 30 adapted to the size of the terminal block 11. No need to manufacture.
[0017]
Further, the lid 30 has a line opening for drawing the lead wires 12a and 12b of the substrate 10 to the outside of the case body 20 in a continuous manner with the terminal opening 31 at a position corresponding to the connection portions 13a and 13b of the substrate 10. 33 is formed. In the present embodiment, since the connection portions 13 a and 13 b are provided on the right side of the terminal block 11, the line opening portion 33 is also formed on the right side of the terminal opening portion 31. The line opening 33 is formed in a substantially U-shaped cross section having a width approximately the same as the diameter of the lead wires 12a and 12b and a size in which the two lead wires 12a and 12b are accommodated side by side. The line opening 33 is not particularly limited to the above position and shape, and can be freely changed.
Further, as shown in FIG. 3, a holding portion 35 is provided at a position facing the upper corner portion of the substrate 10 on the bottom surface of the lid 30. The holding portion 35 is formed to have a groove having a width substantially the same as the thickness of the substrate 10, and the substrate 10 can be fitted into the holding portion 35 and temporarily held on the lid 30 side. Yes.
[0018]
When drawing out the lead wires 12a and 12b, the lead wires 12a and 12b are first passed through the terminal opening 31 having a larger opening area than the line opening 33, and then slid toward the line opening 33 to facilitate the wire drawing. The lead wires 12 a and 12 b can be accommodated in the opening 33. Further, when the substrate 10 and the lid 30 are brought close to each other as they are, the terminal opening 31 is blocked by the terminal block 11, so that the portion where the line opening 33 and the terminal opening 31 are continuous is also blocked by the terminal block 11. Therefore, the lead wires 12a and 12b can be confined in the line opening 33, and the lead wires 12a and 12b can be fixed in the line opening 33.
Further, the substrate 10 is fitted in the holding portion 35 as it is and held on the lid body 30 side, so that the lid body 30 is attached to the case body 20 together with the substrate 10 while fixing the lead wires 12a and 12b in the line opening 33. As a result, the assembling work of the repeater 1 in the state where the lead wires 12a and 12b are pulled out of the case body 20 becomes very easy.
[0019]
In the present embodiment, the lead wires 12a and 12b are directly attached to the substrate 10 with solder. However, the lead wires 12a and 12b may be attached to the substrate 10 via connectors or the like. The present invention can be applied to any configuration in which the lead wires 12a and 12b are attached. Further, the line opening 33 through which the lead wires 12a and 12b are drawn out may not be in communication with the terminal opening 31 as in the present embodiment, and an independent line opening may be provided in the lid 30.
[0020]
【The invention's effect】
As described above, according to the present invention, the case main body is formed in the upper opening and deep in the bottom, and the lid for exposing the terminal block of the board is detachably attached to the upper part, and one end of the lead wire is attached to the board. The lid has a wire opening, and the lead wire is drawn out from the wire opening. Therefore, it is easy to draw out the lead wire directly connected to the board. Since it is only necessary to connect the drawn lead wire to the terminal block of the adjacent repeater, the assembly workability and connection workability of the repeater are improved.
[0021]
Further, according to the present invention, the lid body is provided with a groove-shaped holding portion, and the lead wire is fixed in the wire opening portion by holding the substrate with the holding portion, so when storing the substrate in the case body, With the lead wire fixed to the wire opening, the lid can be attached to the case main body together with the substrate, and the assembly work of the repeater with the lead wire pulled out of the case main body becomes very easy.
[0022]
Further, according to the present invention, the case main body includes the groove-shaped guide portion for positioning the board in the case main body, so that the board can be easily stored in the case main body, and the assembling work of the repeater is facilitated. In addition, the substrate can be positioned within the case body.
