An inverted W-shaped bent portion 26g is formed with only one valley portion 26f. Further, the open end portions 26a and 26b at both ends of the rectangular spring member 26 are parallelly extended outward so as to be parallel to the side edge of the flange portion 43U when being brought into contact with the flange portion 43U of the mounting rail 40. Extension portions 26h and 26i are formed. Here, the square spring member 26 is formed of a spring bar having a diameter substantially equal to the thickness of the flange portion 43U of the mounting rail 40.

バネ支持部２７は、レール装着凹部２１の後側壁における左右方向の中央位置にレール係合部２３Ａ，２３Ｂ側に突出形成されたく字状バネ部材２６の谷部２６ｆに係合する係合突部２７ａを有するとともに、係合突部２７ａの左右位置に形成されたく字状バネ部材２６の２つの山部２６ｄ及び２６ｅを挿通する山部支持部としての挿通孔２７ｂ及び２７ｃを有する。   The spring support portion 27 is an engagement protrusion that engages with a valley portion 26f of a rectangular spring member 26 that is formed to protrude toward the rail engagement portions 23A and 23B at the center position in the left-right direction on the rear side wall of the rail mounting recess 21. 27a, and has insertion holes 27b and 27c as peak portion support portions through which the two peak portions 26d and 26e of the rectangular spring member 26 formed at the left and right positions of the engagement protrusion 27a are inserted.

また、バネ支持部２７は、挿通孔２７ｂ及び２７ｃの外側端部に対向してく字状バネ部材２６の２つの山部２６ｄ及び２６ｅの谷部２６ｆとは反対側の傾斜部を内側から支持するようにレール装着凹部２１の底面から下方に突出形成され内側支持部２７ｄ及び２７ｅを有する。
さらに、バネ支持部２７は、レール装着凹部２１の左右両端側に、く字状バネ部材２６の平行延長部２６ｈ及び２６ｉを個別に挿入支持するとともに、取付レール４０のフランジ部４３Ｒを挿通する係合溝２７ｆを上面側に形成する端部支持部としての係合板部２７ｇ及び２７ｈを有する。 Further, the spring support portion 27 is opposed to the outer end portions of the insertion holes 27b and 27c, and supports an inclined portion on the opposite side to the valley portions 26f of the two peak portions 26d and 26e of the letter-shaped spring member 26 from the inside. Thus, the rail mounting recess 21 protrudes downward from the bottom surface and has inner support portions 27d and 27e.
Further, the spring support portion 27 inserts and supports the parallel extension portions 26h and 26i of the rectangular spring member 26 on both the left and right ends of the rail mounting recess 21 and inserts the flange portion 43R of the mounting rail 40. Engaging plate portions 27g and 27h are provided as end portion supporting portions that form the joint groove 27f on the upper surface side.

そして、バネ支持部２７へのく字状バネ部材２６の組付は、先ず、く字状バネ部材２６を山部２６ｄ及び２６ｅ側を下側とするように斜めに把持して、山部２６ｄ及び２６ｅをバネ支持部２７の挿通孔２７ｂ及び２７ｃに挿通するとともに、谷部２６ｆを係合突部２７ａに係合させ、さらに山部２６ｄ及び２６ｅの外側の傾斜部を内側支持部２７ｄ及び２６ｅに係合させる。この状態から挿通孔２７ｂ及び２７ｃに挿通した山部２６ｄ及び２６ｅを支点として開放端部２６ａ及び２６ｂ側をレール装着凹部２１の底面に接触するように回動させる。このとき、開放端部２６ａ及び２６ｂの平行延長部２６ｈ及び２６ｉが係合板部２７ｇ及び２７ｈの下側の係合溝２７ｆに係合するようにく字状バネ部材２６の開放端部２６ａ及び２６ｂを内側に弾性変形させておく。そして、く字状バネ部材２６がレール装着凹部２１の底面に接触したときにく字状バネ部材２６の弾性変形を解除することにより、く字状バネ部材２６が係合板部２７ｇ及び２７ｈの下側の係合溝２７ｆに係合してバネ支持部２７に保持される。   Then, assembling of the U-shaped spring member 26 to the spring support portion 27 is performed by first gripping the U-shaped spring member 26 obliquely so that the peak portions 26d and 26e are on the lower side, and the peak portion 26d. And 26e are inserted into the insertion holes 27b and 27c of the spring support portion 27, the valley portion 26f is engaged with the engagement protrusion 27a, and the inclined portions outside the peaks 26d and 26e are connected to the inner support portions 27d and 26e. Engage with. From this state, the open end portions 26a and 26b are rotated so as to come into contact with the bottom surface of the rail mounting recess 21 with the peaks 26d and 26e inserted into the insertion holes 27b and 27c as fulcrums. At this time, the open ends 26a and 26b of the rectangular spring member 26 so that the parallel extensions 26h and 26i of the open ends 26a and 26b engage with the lower engaging grooves 27f of the engaging plates 27g and 27h. Is elastically deformed inward. Then, when the square spring member 26 comes into contact with the bottom surface of the rail mounting recess 21, the elastic deformation of the square spring member 26 is released, so that the square spring member 26 moves under the engagement plate portions 27g and 27h. It is engaged with the engagement groove 27 f on the side and is held by the spring support portion 27.

このようにく字状バネ部材２６をバネ支持部２７に保持させた状態では、く字状バネ部材２６の山部２６ｄ及び２６ｅがバネ支持部２７の挿通孔２７ｂ及び２７ｃに挿通され、開放端部２６ａ及び２６ｂに形成された平行延長部２６ｈ及び２６ｉが係合溝２７ｆに係合するので、く字状バネ部材２６が抜け出すことなく確実に保持される。   In this state where the U-shaped spring member 26 is held by the spring support 27, the peaks 26d and 26e of the U-shaped spring member 26 are inserted into the insertion holes 27b and 27c of the spring support 27, and the open end. Since the parallel extending portions 26h and 26i formed in the portions 26a and 26b engage with the engaging groove 27f, the rectangular spring member 26 is securely held without coming out.

そして、このく字状バネ部材２６の保持状態では、く字状バネ部材２６の谷部２６ｆがバネ支持部２７の係合突部２７ａに係合し、く字状バネ部材２６の山部２６ｄ及び２６ｅの谷部２６ｆとは反対側の内側が内側支持部２７ｄ及び２７ｅに支持されるので、図５に示すように、く字状バネ部材２６がその開放端部２６ａ及び２６ｂの平行延長部２６ｈ及び２６ｉがレール装着凹部２１の後壁面２１Ｒと平行な状態に位置決め保持される。したがって、取付レール４０に装着する際に、平行延長部２６ｈ及び２６ｉが取付レール４０に対して均等対峙することになる。   In the holding state of the square spring member 26, the valley portion 26 f of the square spring member 26 engages with the engagement protrusion 27 a of the spring support portion 27, and the peak portion 26 d of the square spring member 26. And 26e are supported by inner support portions 27d and 27e on the inner side opposite to the trough portion 26f. Therefore, as shown in FIG. 5, the U-shaped spring member 26 is a parallel extension portion of its open end portions 26a and 26b. 26h and 26i are positioned and held in a state parallel to the rear wall surface 21R of the rail mounting recess 21. Accordingly, when the mounting rail 40 is mounted, the parallel extensions 26 h and 26 i are evenly opposed to the mounting rail 40.

また、取付レール４０は、図６に示すように、左右方向に延長する中央板部４１とこの中央板部４１の上下端部から後方に延長する上下側板部４２Ｕ及び４２Ｌと、これら上下が板部４２Ｕ及び４２Ｌの後方端部から上方及び下方に延長するフランジ部４３Ｕ及び４３Ｌとでトップハット形レールの構成を有する。
この取付レール４０は熱動形過負荷継電器１を取り付ける配電盤等の例えば垂直な壁面に中央板部４１を５水平方向に配置する関係で固定されている。したがって、フランジ部４３Ｕ及び４３Ｌが垂直壁面に対して上下側板部４２Ｕ及び４３Ｌ分だけ離間した状態となっている。 As shown in FIG. 6, the mounting rail 40 includes a central plate portion 41 extending in the left-right direction, upper and lower side plate portions 42 </ b> U and 42 </ b> L extending rearward from the upper and lower end portions of the central plate portion 41, and the upper and lower sides are plates. The flange portions 43U and 43L extending upward and downward from the rear end portions of the portions 42U and 42L have a top hat rail configuration.
The mounting rail 40 is fixed in such a manner that the central plate portion 41 is arranged in five horizontal directions on a vertical wall surface such as a switchboard to which the thermal overload relay 1 is mounted. Therefore, the flange portions 43U and 43L are separated from the vertical wall surface by the upper and lower side plate portions 42U and 43L.

次に、取付レール４０へのカバー３の取付台部１１を装着する装着方法について説明する。
先ず、例えば、図６に示すように、可動係合部２５が上方側となるようにカバー１０を把持し、この状態で、レール装着凹部２１の可動係合部２５側の底面を取付レール４０のフランジ部４３Ｕにく字状バネ部材２６の平行延長部２６ｈ及び２６ｉと略平行となるように接触させる。 Next, a mounting method for mounting the mounting base 11 of the cover 3 to the mounting rail 40 will be described.
First, for example, as shown in FIG. 6, the cover 10 is gripped so that the movable engagement portion 25 is on the upper side, and in this state, the bottom surface of the rail mounting recess 21 on the movable engagement portion 25 side is attached to the mounting rail 40. The flange portion 43U is brought into contact with the parallel extension portions 26h and 26i of the U-shaped spring member 26 so as to be substantially parallel.

この状態で、カバー１０を下方に押し下げることにより、取付レール４０のフランジ部４３Ｕを、く字状バネ部材２６の平行延長部２６ｈ及び２６ｉをレール装着凹部２１の後壁面２１Ｒ側に撓ませながら、係合板部２７ｇ及び２７ｈの下側の係合溝２７ｆに係合させる。
このとき、前述したように、く字状バネ部材２６がバネ支持部２７に平行延長部２６ｊ及び２６ｋをレール装着凹部２１の後壁面２１Ｒと平行となるように位置決め保持されている。このため、く字状バネ部材２６の逆Ｗ状屈曲部２６ｇがずれて回動することを確実に防止できるので、く字状バネ部材２６の平行延長部２６ｊ及び２６ｋの一方が取付レール４０に片当たりして取付台部１１が取付レール４０に対して斜めに傾斜した状態となることを防止できる。 In this state, the cover 10 is pushed downward to bend the flange portion 43U of the mounting rail 40 and the parallel extensions 26h and 26i of the square spring member 26 toward the rear wall 21R side of the rail mounting recess 21. The engaging plates 27g and 27h are engaged with the lower engaging grooves 27f.
At this time, as described above, the rectangular spring member 26 is positioned and held by the spring support portion 27 so that the parallel extension portions 26j and 26k are parallel to the rear wall surface 21R of the rail mounting recess 21. For this reason, it is possible to reliably prevent the reverse W-shaped bent portion 26g of the letter-shaped spring member 26 from shifting and rotating, so that one of the parallel extensions 26j and 26k of the letter-shaped spring member 26 is attached to the mounting rail 40. It is possible to prevent the mounting base 11 from being inclined and being inclined obliquely with respect to the mounting rail 40.

このようにして係合板部２７ｇ及び２７ｈの下側の係合溝２７ｆに取付レール４０のフランジ部４３Ｕを係合させると、取付レール４０の反対側のフランジ部４３Ｌの側縁にレール装着凹部２１の下側に配置されたレール係合部２３Ａ及び２３Ｂの表面に接触しながらカバー１０が下降する。   In this way, when the flange portion 43U of the mounting rail 40 is engaged with the lower engaging groove 27f of the engaging plate portions 27g and 27h, the rail mounting recess 21 is formed on the side edge of the flange portion 43L on the opposite side of the mounting rail 40. The cover 10 is lowered while being in contact with the surfaces of the rail engaging portions 23A and 23B arranged on the lower side.

その後、取付レール４０のフランジ部４３Ｌの側縁がレール係合部２３Ａ及び２３Ｂ突出端部と接触しない状態となってからカバー１０の取付台部１１を取付レール４０側に押し付けることにより、取付レール４０のフランジ部４３Ｌの表面がレール装着凹部２１の底面に接触する。
この状態で、カバー１０の下方への押圧を解除すると、く字状バネ部材２６の弾性によって、カバー１０の取付台部１１が上方に摺動し、取付レール４０のフランジ部４３Ｌがレール係合部２３Ａ及び２３Ｂの下側の係合溝２２に係合される。 After that, after the side edge of the flange portion 43L of the mounting rail 40 is not in contact with the rail engaging portions 23A and 23B protruding end portions, the mounting base portion 11 of the cover 10 is pressed against the mounting rail 40 side, thereby The surface of the 40 flange portions 43 </ b> L contacts the bottom surface of the rail mounting recess 21.
When the downward pressing of the cover 10 is released in this state, the mounting base 11 of the cover 10 slides upward due to the elasticity of the rectangular spring member 26, and the flange 43L of the mounting rail 40 engages with the rail. It is engaged with the engaging groove 22 on the lower side of the portions 23A and 23B.

そして、係合溝２２の最深部に取付レール４０のフランジ部４３Ｌの側縁が係合すると、カバー１０の取付台部１１の上方への移動が停止されて、取付レール４０の上下のフランジ部４３Ｕ及び４３Ｌにレール装着凹部２１の上下の係合板部２７ｇ及び２７ｈの係合溝２７ｆとレール係合部２３Ａ及び２３Ｂの係合溝２２とに係合した状態でカバー１０の取付台部１１が取付レール４０に装着される。このカバー１０の取付レール４０への装着状態では、く字状バネ部材２６の弾性によって取付台部１１が上方に付勢されているので、レール装着状態が確実に保持される。   When the side edge of the flange portion 43L of the mounting rail 40 is engaged with the deepest portion of the engaging groove 22, the upward movement of the mounting base portion 11 of the cover 10 is stopped, and the upper and lower flange portions of the mounting rail 40 are stopped. The mounting base 11 of the cover 10 is engaged with the engaging grooves 27f of the upper and lower engaging plate portions 27g and 27h of the rail mounting recess 21 and the engaging grooves 22 of the rail engaging portions 23A and 23B in 43U and 43L. Mounted on the mounting rail 40. When the cover 10 is mounted on the mounting rail 40, the mounting base 11 is urged upward by the elasticity of the rectangular spring member 26, so that the rail mounting state is reliably maintained.

その後、又はカバー１０を取付レール４０に装着する前に、カバー１０とケーシング２とを一体化する。
なお、前記カバー１０の取付けは、可動係合部２５を上側として取付レール４０に取り付ける場合に限らず、可動係合部２５を下側として取付レール４０に取付けるようにしてもよい。 Thereafter, or before the cover 10 is attached to the mounting rail 40, the cover 10 and the casing 2 are integrated.
The attachment of the cover 10 is not limited to the case where the movable engagement portion 25 is attached to the attachment rail 40 with the movable engagement portion 25 on the upper side, and the cover 10 may be attached to the attachment rail 40 with the movable engagement portion 25 on the lower side.

以上のように、上記実施形態によると、可動係合部としてく字状バネ部材２６のみを設け、このく字状バネ部材をバネ支持部２７で取付レール４０の側縁に対して均等対峙して保持することかできるので、部品点数を減少させることができる。しかも、く字状バネ部材２６のバネ支持部２７への装着が山部２６ｄ及び２６ｅをバネ支持部２７の挿通孔２７ｂ及び２７ｃに挿通し、この挿通部を支点として開放端側をレール装着凹部２１の底面側に回動させるだけでよく極めて容易に行うことができる。   As described above, according to the above-described embodiment, only the U-shaped spring member 26 is provided as the movable engagement portion, and this U-shaped spring member is evenly opposed to the side edge of the mounting rail 40 by the spring support portion 27. The number of parts can be reduced. In addition, the mounting of the letter-shaped spring member 26 to the spring support part 27 is performed by inserting the peaks 26d and 26e into the insertion holes 27b and 27c of the spring support part 27, and using the insertion part as a fulcrum, the open end side is the rail mounting recess. This can be done very easily by simply rotating it to the bottom side of 21.

さらに、く字状バネ部材２６がバネ支持部２７で取付レール４０の側縁に対して均等対峙して保持することかできるので、カバー１０の取付台部１１を取付レール４０に装着する際にも、く字状バネ部材２６の逆Ｗ字状屈曲部２６ｇがずれることがない。このため、く字状バネ部材２６の平行延長部２６ｈ及び２６ｉを同時に取付レール４０のフランジ部４３Ｕの側縁に接触させることができ、カバー１０の取付台部１１が取付レール４０に対して斜めに装着されることを確実に防止することができる。   Further, since the U-shaped spring member 26 can be held evenly opposed to the side edge of the mounting rail 40 by the spring support portion 27, when the mounting base portion 11 of the cover 10 is mounted on the mounting rail 40. However, the inverted W-shaped bent portion 26g of the letter-shaped spring member 26 is not displaced. For this reason, the parallel extensions 26h and 26i of the rectangular spring member 26 can be brought into contact with the side edge of the flange 43U of the mounting rail 40 at the same time, and the mounting base 11 of the cover 10 is inclined with respect to the mounting rail 40. It can be surely prevented from being attached to.

ちなみに、く字状バネ部材２６に逆Ｗ字状屈曲部２６ｇを設けない場合には、く字状バネ部材２６の屈曲部を例えば挿通孔に挿入して保持したとしても一方の開放端部を押圧したときに、屈曲部が移動してしまい。このため、他方の開放端部がレール装着凹部２１内のレール装着部に突出して取付レール４０のフランジ部４３Ｕの下側に潜り込むことがあり、カバー１０の取付台部１１が斜めに装着されるとともに、不安定な装着状態となる。   Incidentally, when the inverted W-shaped bent portion 26g is not provided on the U-shaped spring member 26, even if the bent portion of the U-shaped spring member 26 is inserted into the insertion hole and held, for example, one open end portion is not provided. When pressed, the bent part moves. For this reason, the other open end portion may protrude into the rail mounting portion in the rail mounting recess 21 and may enter under the flange portion 43U of the mounting rail 40, and the mounting base portion 11 of the cover 10 is mounted obliquely. At the same time, it becomes unstable.

しかしながら、本実施形態では上述したようにく字状バネ部材２６が取付レール４０に対して均等対峙状態で保持されるので、取付レール４０に対して上記のような不安定な状態で装着されることを確実に防止することができる。
なお、上記実施形態においては、く字状バネ部材２６をバネ丸棒材で形成した場合について説明したが、これに限定されるものではなく、バネ角棒材で形成するようにしてもよい。また、く字状バネ部材２６の開放端部は平行延長部２６ｈ及び２６ｉで構成する場合に限らず、取付レール４０に向かって凸となる円弧状に形成するようにしてもよい。 However, in the present embodiment, as described above, the U-shaped spring member 26 is held in an evenly opposed state with respect to the mounting rail 40, so that it is mounted on the mounting rail 40 in an unstable state as described above. This can be surely prevented.
In addition, in the said embodiment, although the case where the square-shaped spring member 26 was formed with a spring round bar material was demonstrated, you may make it form with a spring square bar material, without being limited to this. Further, the open end of the letter-shaped spring member 26 is not limited to being formed by the parallel extensions 26h and 26i, but may be formed in an arc shape that is convex toward the mounting rail 40.

また、バネ支持部２７の内側支持部２７ｄ及び２７ｅの形状も三角柱状に形成する場合に限らず、方形柱状、円柱状等の任意の形状とすることができる。
さらに、上記実施形態では、レール装着装置を熱動形過負荷継電器に適用した場合について説明したが、これに限定されるものではなく、電磁接触器、電磁継電器等の電流路に介挿される任意の電気機器に適用することができる。 Further, the shapes of the inner support portions 27d and 27e of the spring support portion 27 are not limited to being formed in a triangular prism shape, and may be any shape such as a rectangular column shape or a cylindrical shape.
Furthermore, in the above-described embodiment, the case where the rail mounting device is applied to a thermal overload relay has been described. However, the present invention is not limited to this, and an arbitrary one inserted in a current path such as an electromagnetic contactor or an electromagnetic relay. It can be applied to other electrical equipment.
