Description

本発明は、一般住宅や集合住宅に用いられる床暖房パネルに関するものである。   The present invention relates to a floor heating panel used in a general house or a collective house.

従来から、床材の裏面側から熱源体を埋設する凹所を設けて用いられる床暖房パネルが知られている。利用者の好む表面化粧の施された床材を利用することができるため、床暖房装置の周辺部に用いられる床材の選択が、床暖房装置の表面化粧に合う床材を選択するのではなく、利用者が好む表面化粧の床材を床暖房装置とできるため、選択の巾ができ、インテリアコーディネートの面からも好ましいものである。最近では熱源体として、PTC(Positive Temperature Coefficient)ヒーターを面状にしたものを用いると、床材の厚さの中で熱源体を設け、しかもコードヒータのようなヒータ間の温度バラツキがなく、サーモスタットを用いずとも、適切な表面温度を実現する床暖房パネルを構成することが可能となっている(例えば特許文献1など)。   2. Description of the Related Art Conventionally, there is known a floor heating panel that is used by providing a recess in which a heat source body is embedded from the back side of a floor material. Since the flooring with the surface decoration that the user prefers can be used, the selection of the flooring used in the peripheral part of the floor heating device is not to select the flooring that matches the surface decoration of the floor heating device. In addition, since the floor heating material preferred by the user can be used as a floor heating device, a range of selection can be made, which is also preferable from the aspect of interior coordination. Recently, if a PTC (Positive Temperature Coefficient) heater is used as the heat source, a heat source is provided in the thickness of the flooring, and there is no temperature variation between heaters such as a cord heater. It is possible to configure a floor heating panel that realizes an appropriate surface temperature without using a thermostat (for example, Patent Document 1).

この床暖房パネルを用いた床暖房エリアは、用いられる部屋の大きさ、形状にあわせて形成することが望ましいが、一方で、形状に合わせた床暖房パネルを個別に用いることとなると、例えばPTCヒータの特性調整が難しい点、工業的に考えると品番が多くなってしまう点など問題が生じ、したがって、一定形状の床暖房パネルを適宜、横方向、縦方向につなぎ、所望の 床暖房エリアを形成する必要がある。   The floor heating area using the floor heating panel is preferably formed in accordance with the size and shape of the room to be used. On the other hand, if the floor heating panel according to the shape is used individually, for example, PTC Problems such as difficulty in adjusting the characteristics of the heater and the increase in part number due to industrial reasons arise.Therefore, floor heating panels with a fixed shape are connected in the horizontal and vertical directions as appropriate, and the desired floor heating area is set. Need to form.

この床暖房パネルは床材を加工し用いるため、その強度確保のために、床暖房パネル全体を例えばスラブ下地や捨て貼り下地などの下地を用い、面で床暖房パネルを支持する必要がある。そのためこれら床暖房パネル間の配線などは、根太上に捨て貼り下地を設ける場合は配線を下にくぐらせて行うことができるが、そうでない場合には、配線を全てこれら床暖房パネルの厚さ内で行わせる必要がある。この配線は、床暖房パネルの上側から、床暖房パネルの固定後に行えるもの、床暖房パネルの上側から配線をすることができず、床暖房パネル固定前に配線を行い、その後下地上に固定するものの二種類に大別できる。   Since this floor heating panel is processed and used, it is necessary to support the floor heating panel on the surface by using a base such as a slab base or a discarded base for the entire floor heating panel in order to secure its strength. For this reason, wiring between these floor heating panels can be done by throwing them down on the joists and placing them underneath, but if not, all the wiring is the thickness of these floor heating panels. Need to be done within. This wiring can be done from the upper side of the floor heating panel after fixing the floor heating panel, it can not be wired from the upper side of the floor heating panel, it is wired before fixing the floor heating panel and then fixed on the ground There are two types of things.

このうち後者の方法では、配線を容易に行わしめるため、床暖房パネルから配線を引き出し、接続後、再度引き出した配線をそれぞれの床暖房パネルに戻す必要がある。   Of these, in the latter method, in order to carry out wiring easily, it is necessary to draw out the wiring from the floor heating panel, and after connection, return the drawn out wiring to each floor heating panel.

一方、床暖房パネルは、特に耐荷重性を含め床材としての性能も満足する必要がある。そのため配線用のトンネルなど、使用状態で空隙が多くなると、その部分で耐荷重性が劣化するおそれがあり、一方でトンネルを狭く形成しすぎると配線部分が引き出した後に元に戻りにくくなるおそれがあるため、これら相反する特性を満足させる必要があった。   On the other hand, the floor heating panel needs to satisfy the performance as a flooring material including load resistance. Therefore, if there are many gaps in use, such as a tunnel for wiring, there is a risk that the load resistance will deteriorate in that part, while if the tunnel is formed too narrow, it may be difficult to return to the original state after the wiring part is pulled out. Therefore, it was necessary to satisfy these conflicting characteristics.

なお、トンネルの天井部分を樹脂板などの床材を構成する材料以外の補強材で補強する場合もあるが(例えば特許文献2など)、補強材の端部部分が位置する床材表面の強度はやはり高めにくく、逆にその部分で折れるおそれもありうるので、補強材は使わず、できるだけ空隙部分を抑え、床材表面での荷重分散が期待できる構成にするほうが望ましいと考えられる。

In addition, although the ceiling part of the tunnel may be reinforced with a reinforcing material other than the material constituting the floor material such as a resin plate (for example, Patent Document 2), the strength of the floor material surface on which the end portion of the reinforcing material is located Therefore, it is difficult to increase the thickness of the material, and conversely, there is a possibility that the material may break at the portion. Therefore, it is desirable to use a structure that suppresses the void portion as much as possible and can expect load distribution on the floor material surface.

本実施例では、図1などに示されるように、長板状の床材1下面に形成される略方形状のヒータ収納凹所2と、同ヒータ収納凹所2に収容される平面ヒータ3と、該ヒータ収納凹所2の床材1の長手方向一端側から該ヒータ収納凹所2を縦断し、他端側の床材1短手辺端面の側端部分に形成される縦つなぎコネクタ収納部43に至るようにヒータ収納凹所2の底面に形成される縦つなぎ配線溝4と、該縦つなぎ配線溝4を閉塞する閉塞体9と、該縦つなぎ配線溝4に収容され他の床暖房パネル8と縦つなぎ結線される、コード52と縦つなぎコネクタ51からなる配線具5と、を有する床暖房パネル8であって、前記縦つなぎ配線溝4は、床材1の幅方向中心線を挟んで縦つなぎコネクタ収納部43と反対側に、ヒータ収納凹所2の長手方向一端側から他端側に向けて形成される直線溝部41と、該直線溝部41から連続し縦つなぎコネクタ収納部43に至る連結溝部42からなり、該連結溝部42は、縦つなぎコネクタ収納部43から連なる部分を床材中心側方向に略半円状に膨出させ、該膨出部分から連続形成され該膨出部分と略同形状の反転形状に形成される縮小部分とからなり、縦つなぎコネクタ51の挿抜に伴いコード52を連結溝部42内で摺動させるようになしたことを特徴とする床暖房パネル8としている。   In this embodiment, as shown in FIG. 1 and the like, a substantially square heater housing recess 2 formed on the bottom surface of the long plate-like flooring 1 and a flat heater 3 housed in the heater housing recess 2. And a vertical connection connector formed at the side end portion of the short side end surface of the floor material 1 on the other end side of the heater storage recess 2 in the longitudinal direction from one end side in the longitudinal direction of the floor material 1 of the heater storage recess 2 A vertical connecting wiring groove 4 formed on the bottom surface of the heater storing recess 2 so as to reach the storage portion 43, a closing body 9 for closing the vertical connecting wiring groove 4, and other housings accommodated in the vertical connecting wiring groove 4. A floor heating panel 8 having a cord 52 and a wiring tool 5 composed of a vertical connection connector 51 that are connected to the floor heating panel 8 in a vertical connection, wherein the vertical connection wiring groove 4 is the center in the width direction of the flooring 1. The longitudinal direction of the heater housing recess 2 on the opposite side of the connector housing 43 from the vertical connection across the wire The linear groove portion 41 is formed from the end side toward the other end side, and the connecting groove portion 42 continues from the straight groove portion 41 to the vertical connection connector storage portion 43, and the connection groove portion 42 includes the vertical connection connector storage portion 43. The portion connected to the center of the floor is swelled in a substantially semicircular shape, and is composed of a reduced portion formed continuously from the bulged portion and formed in an inverted shape substantially the same shape as the bulged portion. The floor heating panel 8 is characterized in that the cord 52 is slid in the connecting groove portion 42 with the insertion and removal of the connector 51.

図2には、床材1下面のヒータ収納凹所2等の加工状態が示されている。   FIG. 2 shows a processed state of the heater housing recess 2 and the like on the lower surface of the flooring 1.

この床材1には、四周に本実が形成されていて、図の上側及び左側が雄実11、下側と右側が雌実12となっている。そして上側に示されている雄実11の左端部分、つまり縦つなぎコネクタ収納部43と近接する部分は、雄実11の先端部分が切除されている。これは釘打ちを雄実11の付根部分にする際に、誤って縦つなぎコネクタ51などを釘にて傷つけないようにするため、釘をあえて打ち込みにくくするためである。なお、縦つなぎコネクタ収納部43の先端(図の左側部分)は、雄実11が完全に除去され、縦つなぎコネクタ51を引き出せるようにしている。   The floor material 1 is formed with real fruits on all four sides, and the upper and left sides of the figure are male fruits 11, and the lower and right sides are female fruits 12. And the front-end | tip part of the male 11 is cut off in the left end part of the male 11 shown on the upper side, ie, the part which adjoins the vertical connection connector accommodating part 43. FIG. This is to make it difficult for the nail to be driven in order to avoid accidentally damaging the vertical connection connector 51 and the like with the nail when the nail driving is made at the root of the male 11. It should be noted that the end of the vertical connection connector housing portion 43 (left side portion in the figure) is such that the male 11 is completely removed and the vertical connection connector 51 can be pulled out.

そして床材1の縦つなぎコネクタ収納部43が形成されている部分と反対側の短辺(図の右側)付近に、床暖房パネル8の横方向配線用の横送り配線具(これには横送りのハーネス及びハーネスが接続されるコネクタがある。いずれも図示せず)を収納するための凹所が形成されていて、図の上側から、第一横送り溝61、プラグ収納凹所63、コネクタ収納凹所62、先のプラグ収納凹所と向きを反対としたプラグ収納凹所63、そして第二横送り溝64が形成されている。なお、床暖房パネル8の中にハーネスを予めコネクタに接続し収めておいて、床暖房パネル8の横送り配線時にハーネスを引き出し隣接床暖房パネル8に接続させるための余長を吸収するため、第一横送り溝61には、その一部分を広く形成している。   Then, in the vicinity of the short side (right side in the figure) of the floor material 1 on the side opposite to the portion where the vertical connecting connector housing portion 43 is formed, a lateral feed wiring tool for horizontal wiring of the floor heating panel 8 (this includes There is a feed harness and a connector to which the harness is connected (both not shown) are formed with recesses for housing the first lateral feed groove 61, plug housing recess 63, A connector housing recess 62, a plug housing recess 63 opposite to the previous plug housing recess, and a second lateral feed groove 64 are formed. In addition, in order to absorb the extra length for pulling out the harness and connecting it to the adjacent floor heating panel 8 at the time of transverse feed wiring of the floor heating panel 8 by storing the harness in the floor heating panel 8 in advance. A part of the first lateral feed groove 61 is formed wide.

そして残りの部分の所定範囲を暖房範囲として、ヒータ収納凹所2を、本実施例では平面視略長方形で形成している。なおこのヒータ収納凹所2には、長手辺部分を平面ヒータ3の電極32を収めるための電極凹所21をさらに形成している。そしてコネクタから平面ヒータ3への配線を収めるための配線溝46が、カシメなどの接続部分が太くなるため、これを収められるように深さをとっている。なおこのヒータ収納凹所2は、図1、図2で太線で示されているが、正確には平面ヒータ3などを保護する裏板7を収めるための裏板凹所71を床材1の下面に形成し、該裏板凹所71の底面に形成されている。この裏板凹所71は、図2において太線で特に示すように、前述の横送り配線具を収めるための凹所(61〜64)の近傍部分から、該凹所と反対側の、縦つなぎコネクタ収納部43が形成されている側の短辺まで、該縦つなぎコネクタ収納部43を避けるように形成されている。   The heater housing recess 2 is formed in a substantially rectangular shape in plan view in the present embodiment, with the predetermined range of the remaining portion as the heating range. In addition, an electrode recess 21 for accommodating the electrode 32 of the flat heater 3 is further formed in the heater housing recess 2 at the long side portion. The wiring groove 46 for storing the wiring from the connector to the flat heater 3 has a depth so that the connecting portion such as caulking becomes thick so that it can be accommodated. The heater housing recess 2 is indicated by a thick line in FIGS. 1 and 2. To be precise, the back plate recess 71 for housing the back plate 7 for protecting the flat heater 3 and the like is provided on the floor material 1. It is formed on the bottom surface and formed on the bottom surface of the back plate recess 71. This back plate recess 71, as particularly shown by a thick line in FIG. 2, is a vertical joint on the opposite side of the recess from the vicinity of the recesses (61 to 64) for accommodating the above-mentioned lateral feed wiring tools. It is formed so as to avoid the vertically connected connector housing portion 43 up to the short side where the connector housing portion 43 is formed.

そして前述のとおり、縦つなぎ配線溝4は、床材1の幅方向中心線を挟んで縦つなぎコネクタ収納部43と反対側に、ヒータ収納凹所2の長手方向一端側から他端側に向けて形成される直線溝部41と、該直線溝部41から連続し縦つなぎコネクタ収納部に至る連結溝部42からなり、該連結溝部42は、縦つなぎコネクタ収納部43から連なる部分を床材1中心側方向に略半円状に膨出させ、該膨出部分から連続形成され該膨出部分と略同形状の反転形状に形成される縮小部分とからなっている。そのため図2にも示されているように、電極凹所21の一部が縦つなぎ配線溝4により分断されるように形成されている。   And as above-mentioned, the vertical connecting wiring groove | channel 4 is on the opposite side to the vertical connecting connector storage part 43 across the center line of the width direction of the flooring 1, and faces from the longitudinal direction one end side to the other end side of the heater storage recess 2 And a connecting groove portion 42 that continues from the straight groove portion 41 and reaches the vertical connection connector storage portion. The connection groove portion 42 has a portion continuous from the vertical connection connector storage portion 43 at the center side of the flooring 1. It consists of a reduced portion that bulges in a substantially semicircular shape in the direction, is continuously formed from the bulged portion, and is formed in an inverted shape that is substantially the same shape as the bulged portion. Therefore, as shown in FIG. 2, part of the electrode recess 21 is formed so as to be divided by the vertical connecting wiring groove 4.

なお本実施例で用いられている床材1は、合板上にMDF(中質繊維板)、突き板を順に積層一体化したものを用い、上述のように形成されるもののうち、一番深く形成される縦つなぎコネクタ収納部43であっても、その底面は、合板の上から二層までを残して形成されるようにして、床材の構造上の強度を保つようにしている。なお、本実施例の床材以外の層構成であっても、必要とされる床材強度及びコードなどを収容するための必要高さを確保できる限り、例えばMDFだけで床材1を構成しても良く、床材1の層構成、種類は種々のものを用いることができる。   In addition, the flooring 1 used in the present embodiment is one in which MDF (medium fiber board) and a veneer are laminated and integrated in order on a plywood, and is the deepest among those formed as described above. Even in the formed vertical connecting connector housing portion 43, the bottom surface is formed so as to leave two layers from the top of the plywood so as to maintain the structural strength of the flooring. In addition, even if it is a layer structure other than the flooring material of the present embodiment, the flooring material 1 is composed of only MDF, for example, as long as the required flooring material strength and the necessary height for accommodating the cord can be secured. The layer configuration and type of the flooring 1 may be various.

なお、本床暖房パネル8では、合板の面としての強度を活用しているので、縦つなぎコネクタ収納部43のように、床材1の端面が開放した状態だと、その上側部分を支える部位が足りず、結果として表面部分に折れなどの不具合が発生するおそれがある。したがって、縦つなぎコネクタ51が縦つなぎコネクタ収納部43の上面を支えるように収めるようにしている。   In addition, in this floor heating panel 8, since the intensity | strength as a surface of a plywood is utilized, when the end surface of the flooring 1 is the open state like the vertical connection connector storage part 43, the site | part which supports the upper part As a result, there is a possibility that problems such as breaking of the surface portion may occur. Therefore, the vertical connection connector 51 is accommodated so as to support the upper surface of the vertical connection connector housing portion 43.

次に、本実施例の床暖房パネル8を説明する。上述の様に説明した床材1の下面の形状を利用して図3に床暖房パネル8を、図2に示されるa−a’部分で切断した際の端面図として示している。床材1下面に形成された裏板凹所71に裏板7が接着されているが、この裏板7により平面ヒータ3がヒータ収納凹所2の底面(図では上面)に保持されている。そして、平面ヒータ3の電極32やコード52がそれぞれ平面ヒータ3の上側に収められている。   Next, the floor heating panel 8 of the present embodiment will be described. Using the shape of the lower surface of the flooring 1 described above, FIG. 3 shows the floor heating panel 8 as an end view when cut at the a-a ′ portion shown in FIG. 2. The back plate 7 is bonded to the back plate recess 71 formed on the lower surface of the flooring 1, and the flat heater 3 is held by the back plate 7 on the bottom surface (upper surface in the drawing) of the heater housing recess 2. . The electrodes 32 and the cords 52 of the flat heater 3 are housed on the upper side of the flat heater 3, respectively.

なお配線具を構成するコード52は、連結溝部内のコード52を柔軟に形成するとともに、少なくとも縦つなぎコネクタ51の挿抜に伴い縦つなぎコネクタ収納部43から引き出されるコード52を柔軟部分に比べ硬く形成されている。そしてこのコード52は平行電線を用いると供に、柔軟部分は平行電線を分離して形成している。図5は、用いられている平行電線の断面を示している。より線53を樹脂被覆54で略長方形上に断面が形成されていて、二本のより線53間に、V字状の切り込み55が上下に形成されていて、必要に応じこの切り込み55部分を刃物などで切除することで、容易に二本に分離させることができるものである。なお本実施例では、縦つなぎコネクタ51とコード52とは、コード52の先端に設けられたプラグ56を縦つなぎコネクタ51に連結することで行っている。コード52の反対側も同様で、コネクタにプラグを差し込んでいる。これら結線部分の確実性確保のためである。勿論他の方法であっても構わない。   The cord 52 constituting the wiring tool forms the cord 52 in the connecting groove portion flexibly, and forms the cord 52 pulled out from the vertical connection connector housing portion 43 at least when the vertical connection connector 51 is inserted / removed as compared with the flexible portion. Has been. The cord 52 uses a parallel electric wire, and the flexible portion is formed by separating the parallel electric wires. FIG. 5 shows a cross section of the parallel wire used. A cross section of the stranded wire 53 is formed in a substantially rectangular shape with the resin coating 54, and V-shaped cuts 55 are formed vertically between the two stranded wires 53. By excising with a blade or the like, it can be easily separated into two. In this embodiment, the vertical connection connector 51 and the cord 52 are formed by connecting a plug 56 provided at the tip of the cord 52 to the vertical connection connector 51. The other side of the cord 52 is the same, and a plug is inserted into the connector. This is for ensuring the reliability of these connection portions. Of course, other methods may be used.

このようにすると、例えば本実施例のようにコード52を略S字状に湾曲させて用いる場合に、内側と外側のコード52で長さに差が出るため、これを解消するために分離されていない平行電線を用いた場合など特に、コード52が捻じれるが、これを湾曲部分だけ必要に応じ二本に分離しているので、容易に長さの差を解消することができ、コード52の捻じれも解消できる。また二本が合わさっているときの硬さと、分離しているときの硬さとでは、分離している時の硬さのほうが柔らかく、配線具5の出し入れの際に、コード52の変形もこの柔らかい部分で主に行われることが期待できる。本実施例では、図1に符番44で示される部分からコード52を裂いている。勿論、単に樹脂被覆54の硬さを途中で変更するなどしても良いなど、種々の方法が考えられる。なお、符番45で示される部分は、コード52の硬さや縦つなぎ配線溝の形状などにより、製造時にコード52をさらに仮止めすることがあるが、その場合に仮止めをする目安位置である。   In this case, for example, when the cord 52 is bent in a substantially S shape as in the present embodiment, the length is different between the inner cord 52 and the outer cord 52. Therefore, the cord 52 is separated to eliminate this. The cord 52 is twisted, particularly when a parallel electric wire that is not used is used. However, since only the curved portion is separated into two as necessary, the difference in length can be easily eliminated. The twist of can be eliminated. Further, the hardness when the two pieces are combined and the hardness when the two pieces are separated are softer when they are separated, and the deformation of the cord 52 is also soft when the wiring tool 5 is put in and out. It can be expected to be done mainly in the part. In this embodiment, the cord 52 is torn from the portion indicated by reference numeral 44 in FIG. Of course, various methods are conceivable, such as simply changing the hardness of the resin coating 54 halfway. The portion indicated by reference numeral 45 may be further temporarily fixed at the time of manufacture depending on the hardness of the code 52 or the shape of the vertical connecting wiring groove, but is a guide position for temporary fixing in that case. .

平面ヒータ3は、本実施例では図4に示されるようなPTCヒータを用いている。これは、発熱材であるPTC素体31を面状にし、このPTC素体31とこれに密着しPTC素体31に通電するための電極32をPETなどの絶縁体(図示せず)で被覆し形成されている。そしてコネクタと接続するための接続コード33をそれぞれの電極32に接続している。なお、その他平面ヒータ3は種々の態様のものが利用可能だが、PTCヒータは、自身、昇温に伴い抵抗が増大し通電量が抑えられることで、床暖房パネル8の温度をコントロールができるため、サーモスタットなどの補助部品が不要で、結果として床材1内に収めやすくなるという点で、他の平面ヒータに比べて優れている。   In the present embodiment, the flat heater 3 uses a PTC heater as shown in FIG. This is because the PTC element body 31 that is a heat generating material is formed into a planar shape, and the PTC element body 31 and an electrode 32 that is in close contact with the PTC element body 31 and energizes the PTC element body 31 are covered with an insulator (not shown) such as PET. Is formed. A connection cord 33 for connecting to the connector is connected to each electrode 32. In addition, although the thing of various aspects can be used for the other flat heater 3, since the PTC heater itself can control the temperature of the floor heating panel 8 because resistance increases with temperature rising and the amount of electricity supply is suppressed. This is superior to other flat heaters in that an auxiliary part such as a thermostat is unnecessary, and as a result, the thermostat can be easily accommodated in the flooring 1.

なお、床暖房パネル8の製造時に、特にコード52が湾曲する連結溝部42からコード52がはみ出ないように、コード52をテープなどで仮止めをし、連結溝部42と直線溝部41との連通部分に固定状態としている。このようにすることで、例えば縦つなぎ配線溝4からコード52がはみ出し、裏板7の接着密着性を損なうおそれを減ずることや、また裏板7を接着する際に予め、裏板凹所71の底面に、平面ヒータ3を収めた状態で接着剤を塗布するが、その際に接着剤が平面ヒータ3の下側に伝わってきても、コード52が接着剤が伝わりにくい位置になるようにすることなどを防止することができる。   In addition, when the floor heating panel 8 is manufactured, the cord 52 is temporarily fixed with a tape or the like so that the cord 52 does not protrude from the connecting groove portion 42 where the cord 52 is curved, and the connecting portion between the connecting groove portion 42 and the linear groove portion 41 is provided. It is in a fixed state. By doing so, for example, the cord 52 protrudes from the vertical connecting wiring groove 4 to reduce the possibility of impairing the adhesive adhesion of the back plate 7, or when the back plate 7 is bonded, the back plate recess 71 is previously provided. Although the adhesive is applied to the bottom surface of the flat heater 3 in a state in which the flat heater 3 is accommodated, the cord 52 is positioned so that the adhesive is difficult to be transmitted even if the adhesive reaches the lower side of the flat heater 3 at that time. Can be prevented.

なお、平面ヒータ3を閉塞体9として用いているが、平面ヒータ3は、上述の様にPTCヒータを用い、絶縁体の密着形成のため、電極32の外側に、いわゆるヘタが形成されている。このヘタ部分が、裏板凹所71の底面にかかるように載置されている。図1において、平面ヒータ3を点線で示している。   Although the flat heater 3 is used as the closing member 9, the flat heater 3 uses a PTC heater as described above, and a so-called sticker is formed on the outside of the electrode 32 in order to form a close contact with the insulator. . This flat portion is placed so as to cover the bottom surface of the back plate recess 71. In FIG. 1, the flat heater 3 is indicated by a dotted line.

ここで縦つなぎコネクタ51の出し入れに伴うコード52の動きを、図1を用いて説明する。図1は、縦つなぎコネクタ51が引き出されていて、これを矢印の向き(図の右方向)にコード52を押し込みながら戻す様を示している。縦つなぎコネクタ51が引き出された状態では、コード52は連結溝部42の膨出部分とは反対側に引き寄せられている(図中実線されるコード)。なお、図1は説明のため裏板7を除去した状態の図としている。   Here, the movement of the cord 52 associated with the insertion and removal of the vertical connection connector 51 will be described with reference to FIG. FIG. 1 shows that the vertical connection connector 51 is pulled out and returned while pushing the cord 52 in the direction of the arrow (right direction in the figure). In a state in which the vertical connection connector 51 is pulled out, the cord 52 is drawn to the opposite side of the bulging portion of the connecting groove portion 42 (a solid line in the drawing). FIG. 1 shows a state in which the back plate 7 is removed for explanation.

そして押し込む際には、コード52のうち、縦つなぎコネクタ収納部43から引き出される部分を含め、おおよそコード52を略半円状の上記膨出部分にまで押し込むことができるように、必要長だけコード52を裂かずに硬いままにしている部分を利用して、コード52を押し込んでいる(図中一点鎖線で示されるコード52)。そして押し込み途上ではこれらの間をコード52が摺動されていくが、コード52が柔らかく形成されていて、コード52が大きく湾曲しながら移動していく。なお、縦つなぎコネクタ51が収められた状態で丁度裂かれた二本線が膨らまずになるようにしているため、引き出された状態では長さの差があり、若干膨らんだ状態にコード52がなっている。   When the cord 52 is pushed in, the cord 52 including the portion pulled out from the vertical connection connector housing portion 43, including the portion pulled out, can be pushed into the bulging portion having a substantially semicircular shape. The cord 52 is pushed in by utilizing the portion that is left hard without being broken (the cord 52 indicated by a one-dot chain line in the figure). While the cord 52 is being pushed, the cord 52 is slid between them, but the cord 52 is softly formed, and the cord 52 moves while being largely curved. In addition, since the two wires that were just split in the state where the vertical connection connector 51 is accommodated do not swell, there is a difference in length in the pulled-out state, and the cord 52 becomes slightly swelled. ing.
