Description

本発明は、集合端子台装置の接地構造に関する。 The present invention relates to a grounding structure for a collective terminal block device.

配電盤や配電箱等に配設されて、多数のリード線を所要の組合せで相互接続する集合端子台装置が知られている。集合端子台装置は、リード線を相互接続する板状の端子台を厚み方向に複数連結してなる連結端子台を本体とし、連結端子台の両端には、連結端子台を対象物に固定する固定具が配設される。集合端子台装置の多くは、固定具によって連結端子台を据付レール上に固定した状態で、配電盤や配電箱等に設置される（例えば、特許文献１）。また、集合端子台装置の中には、固定具を介して配電盤や配電箱等に連結端子台を直接固定するタイプも知られている（例えば、特許文献２）。 There is known a collective terminal block device which is arranged in a switchboard, a distribution box or the like and interconnects a number of lead wires in a required combination. The collective terminal block device has a connection terminal block formed by connecting a plurality of plate-shaped terminal blocks interconnecting lead wires in the thickness direction, and the connection terminal block is fixed to the object at both ends of the connection terminal block. A fixture is disposed. Many of the collective terminal block devices are installed on a switchboard, a distribution box, or the like in a state where the connection terminal block is fixed on the installation rail by a fixture (for example, Patent Document 1). In addition, among the collective terminal block devices, a type in which a connection terminal block is directly fixed to a switchboard, a distribution box or the like via a fixture is also known (for example, Patent Document 2).

また、こうした集合端子台装置にあって、特許文献２に記載の構成のように、連結端子台の両端に配設される固定具に、接地用リード線を接続するようにしたものが知られている。また、連結端子台を構成する端子台の中に、据付レールと当接して接地されるアース端子台を組み込んでおき、該アース端子台に接地用リード線を接続するようにしたものも知られている（例えば、特許文献３）。 Further, in such a collective terminal block device, as in the configuration described in Patent Document 2, a ground lead wire is connected to a fixture disposed at both ends of a connection terminal block. ing. Also known is a terminal block that constitutes a connecting terminal block, in which a ground terminal block that is in contact with the installation rail and grounded is incorporated, and a grounding lead wire is connected to the ground terminal block. (For example, Patent Document 3).

上記のように、固定具に接地用リード線を接続する構成では、固定具に接地用リード線を複数接続するのが難しいという問題がある。一方で、接地用リード線をアース端子台に接続する構成では接地用リード線を複数接続できるものの、アース端子台は、通常の端子台とは異なる複雑な構造を持つため、コスト高となってしまう。 As described above, the configuration in which the ground lead wire is connected to the fixture has a problem that it is difficult to connect a plurality of ground lead wires to the fixture. On the other hand, in the configuration in which the grounding lead wire is connected to the grounding terminal block, a plurality of grounding lead wires can be connected. However, the grounding terminal block has a complicated structure different from that of a normal terminal block, which increases the cost. End up.

本発明は、かかる現状に鑑みてなされたものであり、複数の接地用リード線を低廉な構成によって接続可能とする集合端子台装置の提供を目的とする。 The present invention has been made in view of the present situation, and an object of the present invention is to provide a collective terminal block device that can connect a plurality of grounding lead wires with an inexpensive configuration.

本発明は、固定具の一方は、該固定具と隣接する端子台の導電金具と圧接するとともに、連結端子台を据付部に固定した状態で据付部と圧接し、前記導電金具と据付部とを電気的に接続するアース金具を備えることを特徴とする集合端子台装置である。ここで「据付部」とは、連結端子台を据付レールに固定するタイプの集合端子台装置では据付レールに相当する。また、連結端子台を配電盤や配電箱等に直接固定するタイプの集合端子台装置では、配電盤や配電箱等に設けられた、集合端子台装置を設置するための台座部分が「据付部」に相当する。 According to the present invention, one of the fixtures is in pressure contact with the conductive metal fitting of the terminal block adjacent to the fixture, and in pressure contact with the installation portion in a state where the connection terminal block is fixed to the installation portion. It is a collective terminal block apparatus provided with the earth | ground metal fitting which electrically connects. Here, the “installation portion” corresponds to an installation rail in a collective terminal block device of a type in which the connection terminal block is fixed to the installation rail. In addition, in the collective terminal block device that directly fixes the connecting terminal block to the switchboard or distribution box, the pedestal part for installing the collective terminal block device provided in the switchboard or distribution box is the `` installation part '' Equivalent to.

かかる構成にあっては、固定具のアース金具が、隣接する端子台の導電金具と据付部とを短絡することにより、当該端子台の導電金具が接地されるため、かかる端子台には、既知のアース端子台同様に、接地用リード線を複数接続することができる。従来のアース端子台は、据付部（据付レール）と電気的に直接接続するため、通常の端子台と比べて構造が複雑であるが、本発明にあって、接地用リード線を接続する端子台は、導電金具にアース金具と圧接する部位が形成されているだけでよいため、既存の導電金具の形状を多少変形するだけで足り、複雑な構造は必要ない。また、固定具は本来的に据付部に固定されるものであるから、固定具を据付部に固定した状態で、アース金具を据付部に圧接させるようにするのは簡単である。このため、本発明によれば、アース端子台を組み込んだ集合端子台装置と同様の機能を、簡単な構成によって低廉に実現可能となる。 In such a configuration, since the grounding metal fitting of the fixture short-circuits the conductive metal fitting of the adjacent terminal block and the installation part, the conductive metal fitting of the terminal block is grounded. As in the case of the earth terminal block, a plurality of ground lead wires can be connected. Since the conventional ground terminal block is electrically connected directly to the installation part (installation rail), the structure is more complicated than that of a normal terminal block. However, in the present invention, the terminal for connecting the ground lead wire Since the platform only needs to be formed on the conductive metal fitting so as to be in pressure contact with the ground metal fitting, it is only necessary to slightly change the shape of the existing conductive metal fitting, and a complicated structure is not necessary. In addition, since the fixture is essentially fixed to the installation portion, it is easy to press the ground metal fitting against the installation portion in a state where the fixture is fixed to the installation portion. For this reason, according to this invention, the function similar to the collective terminal block apparatus incorporating the ground terminal block can be realized at low cost by a simple configuration.

本発明にあって、アース金具を備える固定具は、隣接する端子台と嵌合することによって連結端子台の端部に連結されるものであって、隣接する端子台の方向にアース金具を突出させており、前記固定具と隣接する端子台は、前記固定具と対向する側に導電金具を露出させるとともに、該導電金具に、アース金具と密嵌する接地用開口部を備える構成が提案される。 In the present invention, the fixture including the grounding metal is connected to the end of the connection terminal block by fitting with the adjacent terminal block, and the grounding metal protrudes in the direction of the adjacent terminal block. The terminal block adjacent to the fixture has a configuration in which the conductive metal fitting is exposed on the side facing the fixture, and the conductive metal fitting is provided with a grounding opening that is closely fitted to the ground metal fitting. The

かかる構成にあっては、固定具のアース金具と、隣接する端子台の導電金具とを簡単な構成によって圧接させることができる。また、固定具と端子台を嵌合させるだけで、導電金具とアース金具を圧接させることができるため、固定具と端子台の組付作業も容易となる。 In such a configuration, the grounding metal fitting of the fixture and the conductive metal fitting of the adjacent terminal block can be press-contacted with a simple configuration. In addition, since the conductive metal fitting and the ground metal fitting can be press-contacted only by fitting the fixture and the terminal block, the assembling work of the fixture and the terminal block is facilitated.

また、本発明にあって、連結端子台を構成する各端子台が、同一構成を有していることが提案される。かかる構成にあっては、アース金具を備える固定具と隣接する端子台と、その他の端子台とを同じ構成とすることで、集合端子台装置の部品点数の削減が可能となる。なお、上述のように、固定金具のアース金具と圧接するための構造は簡単なもので済むため、アース金具と圧接しない端子台に同様の構造を設けたとしても、部品点数削減による利点が損なわれることはない。 Moreover, in this invention, it is proposed that each terminal block which comprises a connection terminal block has the same structure. In such a configuration, it is possible to reduce the number of parts of the collective terminal block device by using the same configuration for the terminal block adjacent to the fixture including the ground metal fitting and the other terminal blocks. As described above, since the structure for press-contacting the fixing metal to the earth metal fitting is simple, even if a similar structure is provided on the terminal block that is not press-contacted to the earth metal fitting, the advantage of reducing the number of parts is lost. It will never be.

本発明の具体的な構成としては、据付部は、上端に幅方向に突出する連係板座を備える据付レールであり、アース金具を備える固定具は、アース金具を備える固定具本体と、挟圧金具とを備えてなり、固定具本体と挟圧金具とをネジで締結してアース金具と挟圧金具との間に連係板座を挟持することによって据付レールに固定されるものである構成が提案される。かかる構成によれば、据付レールに固定するタイプの集合端子台装置に、本発明を適切に採用できる。 As a specific configuration of the present invention, the installation part is an installation rail provided with a linkage plate seat protruding in the width direction at the upper end, and the fixture provided with the ground metal fitting is a fixture main body provided with the ground metal fitting, and the clamping pressure And the fixture body and the clamping metal fitting are fastened to the installation rail by fastening them with screws and sandwiching the linkage plate seat between the grounding metal fitting and the clamping metal fitting. Proposed. According to such a configuration, the present invention can be appropriately employed in a collective terminal block device of a type that is fixed to the installation rail.

また、本発明の具体的な構成としては、アース金具を備える固定具は平坦な据付部の上に螺着されるものであり、アース金具は、固定具本体の底部に露出して、固定具を据付部に螺着した状態で据付部と圧接する底辺部を備える構成も提案される。かかる構成によれば、配電盤や配電箱等に直接固定するタイプの集合端子台装置に、本発明を適切に採用できる。 Further, as a specific configuration of the present invention, a fixture provided with a grounding fixture is screwed onto a flat installation portion, and the grounding fixture is exposed at the bottom of the fixture main body, A configuration is also proposed that includes a bottom portion that press-contacts the installation portion in a state where the installation portion is screwed to the installation portion. According to such a configuration, the present invention can be appropriately employed in a collective terminal block device of a type that is directly fixed to a distribution board, a distribution box or the like.

また、本発明の別の態様は、リード線を導電金具を介して相互接続する端子台を複数列設してなる連結端子台の端部に連結され、金属製の据付部に固定されることにより連結端子台を据付部に固定する固定具であって、連結端子台の端部に連結された状態で、連結端子台側に突出して連結端子台の端部に位置する端子台の導電金具に圧接するとともに、据付部に固定された状態で据付部と圧接し、前記導電金具と据付部とを電気的に接続するよう構成されたことを特徴とする固定具である。かかる固定具を用いれば、簡単な構成によって連結端子台の端部に位置する端子台を接地できるから、既知のアース端子台と同様の機能を低廉に実現できる。 Another aspect of the present invention is that the lead wire is connected to an end portion of a connection terminal block in which a plurality of terminal blocks for interconnecting the lead wires through the conductive metal fittings are provided, and is fixed to a metal installation portion. A fixture for fixing the connecting terminal block to the installation part by the terminal, and in a state where it is connected to the end of the connecting terminal block, it protrudes toward the connecting terminal block and is located at the end of the connecting terminal block. In addition, the fixture is configured to be in pressure contact with the installation portion and in pressure contact with the installation portion to electrically connect the conductive metal fitting and the installation portion. If such a fixture is used, the terminal block located at the end of the connecting terminal block can be grounded with a simple configuration, so that the same function as a known ground terminal block can be realized at low cost.

以上に述べたように、本発明によれば、従来構成に比べて、複数の接地用リード線を低廉な構成によって接続することが可能となる。 As described above, according to the present invention, it is possible to connect a plurality of grounding lead wires with an inexpensive configuration as compared with the conventional configuration.

本実施例の集合端子台装置１は、図１，２に示すように、金属製の据付レール（据付部）２に装着するタイプであり、端子台６を複数列設してなる連結端子台３と、該連結端子台３に配設されて、連結端子台３を据付レール２に固定する固定具４，５とを備え、据付レール２に固定した状態で配電盤や配電箱等に設置される。 As shown in FIGS. 1 and 2, the collective terminal block device 1 of the present embodiment is a type that is mounted on a metal installation rail (installation section) 2, and is a connecting terminal block in which a plurality of terminal blocks 6 are arranged. 3 and fixtures 4 and 5 which are disposed on the connection terminal block 3 and fix the connection terminal block 3 to the installation rail 2, and are installed on a switchboard or distribution box in a state of being fixed to the installation rail 2. The

据付レール２は、図１，２に示すように、両側部に立設された立ち上がり側壁１０，１０の上端に、幅方向内側へ突出する連係板座１１，１１を長手方向に沿って形成してなり、連結端子台３の底部の両側部位を連係板座１１，１１の上に載せるとともに、連結端子台３の底部の中央部位を連係板座１１の間に形成された保持溝１２に内嵌保持するものである。 As shown in FIGS. 1 and 2, the installation rail 2 has linkage plate seats 11, 11 protruding inward in the width direction at the upper ends of the rising side walls 10, 10 erected on both sides along the longitudinal direction. The both sides of the bottom of the connection terminal block 3 are placed on the linkage plate seats 11, 11, and the central portion of the bottom of the connection terminal block 3 is placed in the holding groove 12 formed between the linkage plate seats 11. Fit and hold.

本実施例にあって、連結端子台３を構成する端子台６は、全て同一構成をなしている。これらの端子台６は、図３，４に示すように、リード線の端部をバネ力で保持するバネ式端子台である。具体的には、端子台６は、ポリアミド等の絶縁性樹脂材料によって板状に形成された左右対称の絶縁性基板１５を主体部とする。この絶縁性基板１５には、正面側に開放する装着溝部１６が形成されており、該装着溝部１６に導電金具１７と板バネ１８とが装着される。絶縁性基板１５の上部には、装着溝部１６と連通するリード線挿入孔２０が左右両側に２つずつ形成されており、圧着端子を取り付けたリード線の端部を各リード線挿入孔２０の奥まで挿入すると、導電金具１７と板バネ１８の間で圧着端子が挟持され、導電金具１７を介して各リード線が相互接続されるよう構成されている。また、各リード線挿入孔２０の外側には、装着溝部１６と連通するドライバー挿入孔２１が形成されており、ドライバー挿入孔２１にドライバーを挿入し、ドライバーの先端で板バネ１８を撓ませることにより、板バネ１８に挟持されたリード線を引き抜き得るよう構成されている。また、絶縁性基板１５の正面側には、連結用孔部２２が形成される。この連結用孔部２２は、端子台６同士を厚み方向に連結するのに用いられ、また、端子台６の正面側に固定具４を連結するのにも用いられる。そして、本実施例にあっては、導電金具１７の正面側に、横長矩形状の接地用開口部２３が形成される。この接地用開口部２３は端子台６の正面側に露出しており、導電金具１７は、かかる接地用開口部２３において、固定具４のアース金具２９と圧接し得るよう構成される。なお、かかる端子台６は、導電金具１７に形成された接地用開口部２３以外の構成は公知であるため、公知の構成についての詳細な説明は省略する。 In this embodiment, the terminal blocks 6 constituting the connecting terminal block 3 all have the same configuration. As shown in FIGS. 3 and 4, these terminal blocks 6 are spring-type terminal blocks that hold the ends of the lead wires with a spring force. Specifically, the terminal block 6 includes a symmetrical symmetrical insulating substrate 15 formed in a plate shape by an insulating resin material such as polyamide as a main part. The insulating substrate 15 is provided with a mounting groove 16 that opens to the front side, and a conductive metal fitting 17 and a leaf spring 18 are mounted in the mounting groove 16. Two lead wire insertion holes 20 communicating with the mounting groove portion 16 are formed on the upper side of the insulating substrate 15 on each of the left and right sides, and the end of the lead wire to which the crimp terminal is attached is connected to each lead wire insertion hole 20. When inserted to the back, the crimp terminal is sandwiched between the conductive fitting 17 and the leaf spring 18, and the lead wires are interconnected via the conductive fitting 17. Further, a driver insertion hole 21 communicating with the mounting groove portion 16 is formed outside each lead wire insertion hole 20, and a driver is inserted into the driver insertion hole 21, and the leaf spring 18 is bent at the tip of the driver. Thus, the lead wire sandwiched between the leaf springs 18 can be pulled out. A connecting hole 22 is formed on the front side of the insulating substrate 15. The connecting hole 22 is used to connect the terminal blocks 6 in the thickness direction, and is also used to connect the fixture 4 to the front side of the terminal block 6. In the present embodiment, a horizontally elongated rectangular opening 23 is formed on the front side of the conductive metal fitting 17. The grounding opening 23 is exposed on the front side of the terminal block 6, and the conductive metal fitting 17 is configured to be able to press-contact with the grounding metal 29 of the fixture 4 in the grounding opening 23. Since the terminal block 6 has a known configuration other than the grounding opening 23 formed in the conductive metal member 17, a detailed description of the known configuration is omitted.

固定具４，５は、図１，２に示すように、連結端子台３の端部に連結されて、据付レール２に固定されることにより、連結端子台３を据付レール２の上に固定するものである。この固定具４，５のうち、導電金具１７が露出する端子台６の正面側に連結される固定具４は、該固定具４に隣接する端子台６と据付レール２とを電気的に接続する接地用固定具を構成する。すなわち、かかる接地用固定具４は、本発明に係る「アース金具を備える固定具」に相当するものである。一方、端子台６の背面側に連結される固定具５は、連結端子台３を据付レール２に固定するためだけに用いられる通常固定具５である。 As shown in FIGS. 1 and 2, the fixtures 4 and 5 are connected to the end of the connection terminal block 3 and fixed to the installation rail 2, thereby fixing the connection terminal block 3 on the installation rail 2.

Among the fixtures 4 and 5, the fixture 4 connected to the front side of the terminal block 6 where the conductive metal fitting 17 is exposed electrically connects the terminal block 6 adjacent to the fixture 4 and the installation rail 2. Constituting a grounding fixture. That is, the grounding fixture 4 corresponds to “a fixture having a grounding fixture” according to the present invention. On the other hand, the fixture 5 connected to the back side of the terminal block 6 is a normal fixture 5 used only for fixing the connection terminal block 3 to the installation rail 2.

接地用固定具４は、図５，６に示すように、連結端子台３の端部に連結される固定具本体２５と、固定具本体２５の下方に配置されて固定ネジ２７によって固定具本体と締結される挟圧金具２６とを備えてなる。固定具本体２５は、図７に示すように、樹脂製のベース部材２８とアース金具２９とで構成される。ベース部材２８は、肉厚板状の側板部３２と、該側板部３２の下部から正面側に延出する固定部３３とからなる。側板部３２は、隣接する端子台６の正面側を覆うようにして連結するものであり、図８に示すように、側板部３２の、端子台６と対向する側には、端子台６の連結用孔部２２と嵌合する連結突起３４が形成される。また、側板部３２の、端子台６の接地用開口部２３と対向する位置には、アース金具２９が貫通することとなる前後方向の金具貫通孔３５が形成される。一方、固定部３３は、挟圧金具２６との間で据付レール２を挟持するものであり、その中央部には、固定ネジ２７が貫通するネジ貫通孔３７が上下に形成される。 As shown in FIGS. 5 and 6, the grounding fixture 4 includes a fixture main body 25 connected to the end portion of the connection terminal block 3, and a fixture main body disposed below the fixture main body 25 by a fixing screw 27. And a clamping metal fitting 26 to be fastened. As shown in FIG. 7, the fixture body 25 includes a resin base member 28 and a grounding metal 29. The base member 28 includes a thick plate-like side plate portion 32 and a fixing portion 33 extending from the lower portion of the side plate portion 32 to the front side. The side plate portion 32 is connected so as to cover the front side of the adjacent terminal block 6, and as shown in FIG. 8, the side plate portion 32 has a terminal plate 6 on the side facing the terminal block 6. A connection protrusion 34 that fits into the connection hole 22 is formed. Further, a metal through hole 35 in the front-rear direction through which the earth metal fitting 29 penetrates is formed at a position of the side plate portion 32 facing the ground opening 23 of the terminal block 6. On the other hand, the fixing portion 33 holds the mounting rail 2 between the pinching metal fittings 26, and a screw through hole 37 through which the fixing screw 27 passes is formed vertically in the center portion thereof.

アース金具２９は、図７，８に示すように、鋼板を側面視略コ字状に屈曲加工してなるものであり、ベース部材２８の固定部３３に外嵌するようにベース部材２８に組み付けられる。具体的には、アース金具２９は、固定部３３の正面に被着する側辺部３８と、固定部３３の上面に被着する上辺部３９と、固定部３３の底面に被着する底辺部４０とを備えている。アース金具２９の上辺部３９と底辺部４０には、固定部３３のネジ貫通孔３７と重なる位置にネジ貫通孔４１，４１が形成される。そして、上辺部３９には、図８に示すように、ベース部材２８の金具貫通孔３５を貫通し、その先端を側板部３２の背面側（端子台６側）に突出させる差込部４３が形成される。この差込部４３は、平行に延出する左右一対の杆状部４３ａ，４３ａによって構成される。この差込部４３は、図９に示すように、隣接する端子台６の導電金具１７の接地用開口部２３と対向する位置に突出しており、側板部３２の連結突起３４を端子台６の連結用孔部２２に嵌合させて、接地用固定具４を端子台６の正面側に連結すると、差込部４３の先端部が接地用開口部２３に内嵌するよう構成されている。ここで、差込部４３の幅寸法は、接地用開口部２３の幅寸法よりも若干広く設計されており、差込部４３は、接地用開口部２３に内嵌する時に杆状部４３ａを内側に撓ませることにより、杆状部４３ａを接地用開口部２３の内周縁に圧接した密嵌状態となるよう構成されている。 As shown in FIGS. 7 and 8, the ground metal fitting 29 is formed by bending a steel plate into a substantially U shape when viewed from the side, and is assembled to the base member 28 so as to be externally fitted to the fixing portion 33 of the base member 28. It is done. Specifically, the ground metal fitting 29 includes a side portion 38 that is attached to the front surface of the fixing portion 33, an upper side portion 39 that is attached to the upper surface of the fixing portion 33, and a bottom portion that is attached to the bottom surface of the fixing portion 33. 40. Screw through holes 41 and 41 are formed in the upper side portion 39 and the bottom side portion 40 of the ground metal fitting 29 at positions overlapping the screw through holes 37 of the fixing portion 33. As shown in FIG. 8, the upper side portion 39 has an insertion portion 43 that passes through the metal fitting through-hole 35 of the base member 28 and protrudes its tip to the back side (terminal block 6 side) of the side plate portion 32. It is formed. The insertion portion 43 is composed of a pair of left and right flanges 43a and 43a extending in parallel. As shown in FIG. 9, the insertion portion 43 protrudes to a position facing the grounding opening 23 of the conductive metal fitting 17 of the adjacent terminal block 6, and the connection protrusion 34 of the side plate portion 32 is connected to the terminal projection 6. When the grounding fixture 4 is coupled to the front side of the terminal block 6 by being fitted into the coupling hole 22, the distal end portion of the insertion portion 43 is configured to be fitted into the grounding opening 23. Here, the width dimension of the insertion portion 43 is designed to be slightly larger than the width dimension of the grounding opening portion 23, and the insertion portion 43 has a hook-shaped portion 43 a when fitted into the grounding opening portion 23. By bending inward, the hook-shaped portion 43a is configured to be in close contact with the inner peripheral edge of the grounding opening 23.

挟圧金具２６は、鋼板片を屈曲加工してなるものであり、図５，６に示すように、固定部３３の底部と対向する底板部４５と、該底板部４５の両側に形成される挟圧爪部４６と、底板部４５の中央部前縁から上方に延出して、アース金具２９の側辺部３８と当接する前板部４７とを備えている。挟圧金具２６の底板部４５には、固定具本体２５のネジ貫通孔３７，４１と対向する位置にネジ孔４８が形成されており、図５に示すように、固定具本体２５の固定部３３の底部に挟圧金具２６を配置し、固定ネジ２７をネジ貫通孔３７，４１に挿通して、挟圧金具２６のネジ孔４８と螺合させることにより、固定具本体２５と挟圧金具２６を締結し得るよう構成されている。 The clamping metal fitting 26 is formed by bending a steel plate piece, and is formed on the bottom plate portion 45 facing the bottom portion of the fixing portion 33 and on both sides of the bottom plate portion 45 as shown in FIGS. A pinching claw portion 46 and a front plate portion 47 that extends upward from the front edge of the center portion of the bottom plate portion 45 and contacts the side portion 38 of the ground metal fitting 29 are provided. A screw hole 48 is formed in the bottom plate portion 45 of the clamping metal fitting 26 at a position facing the screw through holes 37 and 41 of the fixture main body 25. As shown in FIG. The clamp body 26 is disposed at the bottom of the 33, the fixing screw 27 is inserted into the screw through holes 37 and 41, and is screwed into the screw holes 48 of the clamp hardware 26, thereby fixing the fixture body 25 and the clamp metal fitting. 26 can be fastened.

接地用固定具４を据付レール２に固定する場合は、図１０に示すように、固定具本体２５の両側部を据付レール２の連係板座１１，１１の上に載せるとともに、両挟圧爪部４６，４６が連係板座１１，１１の下側に位置するように挟圧金具２６を固定具本体２５の下方に配置し、固定具本体２５と挟圧金具２６を固定ネジ２７によって締結する。かかる締結状態では、固定ネジ２７の締結力によって、固定具本体２５と挟圧金具２６の間に連係板座１１が挟持され、これにより、接地用固定具４が据付レール２に固定される。 When fixing the grounding fixture 4 to the installation rail 2, as shown in FIG. 10, both side portions of the fixture body 25 are placed on the connecting plate seats 11, 11 of the installation rail 2 and both clamping claws. The clamping metal fitting 26 is arranged below the fixture body 25 so that the portions 46, 46 are located below the linkage plate seats 11, 11, and the fixture body 25 and the clamping metal fitting 26 are fastened by a fixing screw 27. . In such a fastening state, the coupling plate seat 11 is sandwiched between the fixture main body 25 and the clamping metal fitting 26 by the fastening force of the fixing screw 27, whereby the grounding fixture 4 is fixed to the installation rail 2.

一方、接地用固定具４に対して、連結端子台３の反対側に配設される通常固定具５は、接地用固定具４からアース金具２９を除いた構成を有している。すなわち、通常固定具５は、接地用固定具４のベース部材２８のみからなる固定具本体と、挟圧金具２６とによって構成される。かかる通常固定具５は、図１１に示すように、接地用固定具４同様に、固定具本体（ベース部材）２８と挟圧金具２６とを固定ネジ２７で締結し、固定具本体２８と挟圧金具２６の間に連係板座１１を挟持することによって、据付レール２に固定される。 On the other hand, the normal fixture 5 disposed on the opposite side of the connection terminal block 3 with respect to the grounding fixture 4 has a configuration in which the grounding fixture 29 is removed from the grounding fixture 4. That is, the normal fixture 5 is constituted by a fixture main body composed only of the base member 28 of the grounding fixture 4 and the clamping metal fitting 26. As in the case of the grounding fixture 4, the normal fixture 5 is fastened to a fixture main body (base member) 28 and a clamping metal fitting 26 with a fixing screw 27, so that the fixture fixture 28 is clamped. The linkage plate seat 11 is sandwiched between the press fittings 26 to be fixed to the installation rail 2.

以上の構成によれば、図１１に示すように、固定具本体と挟圧金具２６とを分離、若しくは緩く締結した状態で、連結端子台３を据付レール２の上に設置し、かかる状態で固定ネジ２７を締め付けて各固定具４，５を据付レール２に固定すれば、連結端子台３を据付レール２に固定できる。このように、連結端子台３を据付レール２に固定した状態では、図１２に示すように、接地用固定具４のアース金具２９が、側辺部３８の両側下縁部分で、据付レール２の連係板座１１と圧接することとなり、これにより、アース金具２９を介して、隣接する端子台６の導電金具１７と据付レール２とが電気的に接続される。このように、本実施例の集合端子台装置１は、据付レール２に固定した状態で、接地用固定具４に隣接する端子台６の導電金具１７が、据付レール２と電気的に接続されるため、既知のアース端子台同様に、かかる端子台６に接地用リード線を接続することで、当該リード線を接地可能となる。 According to the above configuration, as shown in FIG. 11, the connection terminal block 3 is installed on the installation rail 2 in a state where the fixture body and the clamping metal fitting 26 are separated or loosely fastened, and in this state. If the fixing screws 27 are tightened to fix the fixtures 4 and 5 to the installation rail 2, the connection terminal block 3 can be fixed to the installation rail 2. Thus, in the state where the connection terminal block 3 is fixed to the installation rail 2, as shown in FIG. 12, the ground metal fitting 29 of the grounding fixture 4 is installed at the lower edge portions on both sides of the side portion 38. Thus, the conductive metal plate 17 of the adjacent terminal block 6 and the installation rail 2 are electrically connected via the ground metal fitting 29. As described above, in the collective terminal block device 1 of the present embodiment, the conductive fitting 17 of the terminal block 6 adjacent to the grounding fixture 4 is electrically connected to the installation rail 2 while being fixed to the installation rail 2. Therefore, like the known ground terminal block, the lead wire can be grounded by connecting the ground lead wire to the terminal block 6.

以上のように、本実施例の集合端子台装置１では、接地用固定具４に設けられたアース金具２９が、据付レール２と、隣接する端子台６の導電金具１７とを電気的に接続するため、接地用固定具４に隣接する端子台６の各リード線挿入孔２０に、接地用リード線を夫々接続可能となる。ここで、本実施例にあって、接地用リード線を接続する端子台６を接地するために設けられた構成は、端子台６については、導電金具１７に形成した接地用開口部２３のみである。また、接地用固定具４については、固定具本体２５に設けたアース金具２９のみであり、その他の構成は、通常固定具５と共通している。このため、本実施例では、端子台６の導電金具１７に接地用開口部２３を形成し、接地用固定具４にアース金具２９を配設するだけの簡単な構成によって、アース端子台を備える従来の集合端子台装置と同様の機能を実現できるという利点がある。 As described above, in the collective terminal block device 1 of the present embodiment, the grounding fitting 29 provided on the grounding fixture 4 electrically connects the installation rail 2 and the conductive fitting 17 of the adjacent terminal block 6. Therefore, the ground lead wire can be connected to each lead wire insertion hole 20 of the terminal block 6 adjacent to the grounding fixture 4.

Further, the grounding fixture 4 is only the ground metal fitting 29 provided in the fixture main body 25, and the other configuration is common to the normal fixture 5. For this reason, in this embodiment, the grounding terminal 23 is provided with a simple configuration in which the grounding opening 23 is formed in the conductive metal 17 of the terminal block 6 and the grounding metal 29 is disposed in the grounding fixture 4. There is an advantage that functions similar to those of the conventional collective terminal block device can be realized.

また、本実施例では、接地用固定具４を、端子台６の導電金具１７が露出する側に嵌合させるとともに、アース金具２９の差込部４３を当該端子台６の方向に突出させて、接地用固定具４と端子台６を嵌合させた時に、差込部４３が接地用開口部２３に密嵌するように構成しているから、接地用固定具４を連結端子台３の端部の端子台６に連結するだけで、当該端子台６の導電金具１７とアース金具２９とを電気的に接続できるという利点がある。 Further, in this embodiment, the grounding fixture 4 is fitted to the side of the terminal base 6 where the conductive metal fitting 17 is exposed, and the insertion portion 43 of the ground metal fitting 29 is protruded in the direction of the terminal base 6. When the grounding fixture 4 and the terminal block 6 are fitted, the insertion portion 43 is configured to closely fit into the grounding opening 23, so that the grounding fixture 4 is connected to the connection terminal block 3. There is an advantage that the conductive metal fitting 17 and the earth metal fitting 29 of the terminal block 6 can be electrically connected only by being connected to the terminal block 6 at the end.

また、本実施例にあっては、接地用固定具４と隣接する端子台６以外にも、接地用開口部２３が形成されており、連結端子台３を構成する全ての端子台６が同一構成を有している。このため、本実施例では、接地用リード線を接続する端子台と、その他の端子台とを共通部品化し、集合端子台装置の製造コストを削減できるという利点がある。 In the present embodiment, in addition to the terminal block 6 adjacent to the grounding fixture 4, the grounding opening 23 is formed, and all the terminal blocks 6 constituting the connection terminal block 3 are the same. It has a configuration. For this reason, in this embodiment, there is an advantage that the terminal block to which the ground lead wire is connected and the other terminal block are made into a common component, and the manufacturing cost of the collective terminal block device can be reduced.

本実施例の集合端子台装置１ａは、図１３に示すように、固定具４ａ，５ａによって、配電盤や配電箱等に設けられる金属製の台座５０（据付部）に直接固定するタイプである。本実施例の集合端子台装置１ａは、上記実施例１から、固定具４，５の挟圧金具２６を除去しただけの構成であり、連結端子台３等のその他の構成は実施例１と同じである。すなわち、本実施例に係る接地用固定具４ａは、図１４に示すように、ベース部材２８とアース金具２９とからなる固定具本体２５のみによって構成される。また、通常固定具５ａは、ベース部材２８のみによって構成される。なお、本実施例にあって、実施例１と構成の共通する部分については、図中で符号を共通させて説明を省略する。 As shown in FIG. 13, the collective terminal block device 1a according to the present embodiment is of a type that is directly fixed to a metal base 50 (installation section) provided on a switchboard, a distribution box or the like by fixtures 4a and 5a. The collective terminal block device 1a of the present embodiment has a configuration in which only the clamping metal fittings 26 of the fixtures 4 and 5 are removed from the above-described first embodiment. The same. That is, the grounding fixture 4a according to the present embodiment is constituted only by a fixture main body 25 including a base member 28 and a grounding metal 29, as shown in FIG. Further, the normal fixture 5a is constituted only by the base member 28. In the present embodiment, portions common to those in the first embodiment are denoted by the same reference numerals in the drawing and description thereof is omitted.

本実施例の集合端子台装置１ａを設置する台座５０は、図１５に示すように、配電盤や配電箱等に設けられた平坦な金属板であり、集合端子台装置１ａは、固定ネジ２７を固定具４ａ，５ａに挿通し、台座５０に形成されたネジ孔５１に螺着することによって、台座５０の上に固定される。集合端子台装置１ａを台座５０に固定した状態では、
アース金具２９が、接地用固定具４の底部に露出する底辺部４０を台座５０の表面に圧接することとなり、これにより、アース金具２９を介して、隣接する端子台６の導電金具１７と台座５０とが電気的に接続される。このように、本発明の集合端子台装置は、据付レールを介さずに、対象物に直接固定するタイプにも適用可能である。 As shown in FIG. 15, the pedestal 50 on which the collective terminal block device 1a of the present embodiment is installed is a flat metal plate provided on a switchboard, a distribution box or the like, and the collective terminal block device 1a includes a fixing screw 27. It is fixed on the pedestal 50 by being inserted into the fixtures 4 a and 5 a and screwed into a screw hole 51 formed in the pedestal 50. In a state where the collective terminal block device 1a is fixed to the base 50,
The ground metal fitting 29 presses the bottom 40 exposed at the bottom of the grounding fixture 4 to the surface of the pedestal 50, whereby the conductive metal fitting 17 and the pedestal of the adjacent terminal block 6 are connected via the ground metal fitting 29. 50 is electrically connected. Thus, the collective terminal block device of the present invention is also applicable to a type that is directly fixed to an object without using an installation rail.

なお、本発明の集合端子台装置は、上記実施例の形態に限らず本発明の要旨を逸脱しない範囲内において種々変更を加えることができる。例えば、上記実施例では、端子台が、リード線の端部をバネ力で保持するバネ式端子台であったが、本発明に係る端子台にあって、リード線の接続方式は特に限定されるものではなく、例えば、リード線の端部をネジ止めする端子台を採用することもできる。また、端子台の導電金具は複数部材で構成されていてもかまわない。また、上記実施例に係る固定具は、据付部にネジ止めするものであるが、本発明に係る固定具はネジ以外の手段によって据付部に固定するものであってもよい。上記実施例に係る固定具本体は、樹脂製のベース部材とアース金具とによって構成されているが、本発明に係る固定具は全て金属で構成することもできる。また、上記実施例では、アース金具が一片の金属片によって構成されているが、本発明に係るアース金具は、複数の金属部材によって構成することもできる。例えば、実施例１では、図１２に示すように、単体の金属片であるアース金具２９が、導電金具１７と据付レール２とを短絡しているが、アース金具２９を据付レール２に当接させず、挟圧金具２６を介してアース金具２９と据付レール２を電気的に接続するようにしてもよい。かかる構成とした場合は、導電金具１７と据付レール２が、アース金具２９と挟圧金具２６の二部材によって短絡されるから、挟圧金具２６が本発明に係るアース金具に含まれることとなる。また、同様に、実施例２では、アース金具２９を台座５０に当接させず、金属製の固定ネジ２７を用いてアース金具２９と台座５０とを電気的に接続するようにしてもよい。かかる構成とした場合は、導電金具１７と台座５０が、アース金具２９と固定ネジ２７の二部材によって短絡されるから、固定ネジ２７が本発明に係るアース金具に含まれることとなる。 The collective terminal block device of the present invention is not limited to the embodiment described above, and various modifications can be made without departing from the gist of the present invention. For example, in the above embodiment, the terminal block is a spring type terminal block that holds the end portion of the lead wire with a spring force. However, in the terminal block according to the present invention, the connection method of the lead wire is particularly limited. For example, a terminal block for screwing the end of the lead wire may be employed. Moreover, the conductive metal fitting of the terminal block may be composed of a plurality of members. Moreover, although the fixing tool which concerns on the said Example is screwed to an installation part, the fixing tool which concerns on this invention may be fixed to an installation part by means other than a screw | thread. Although the fixing tool main body according to the above-described embodiment is configured by a resin base member and a grounding metal fitting, the fixing tool according to the present invention can also be configured by metal. Moreover, in the said Example, although the earth metal fitting was comprised by the piece of one metal piece, the earth metal fitting which concerns on this invention can also be comprised by a some metal member. For example, in the first embodiment, as shown in FIG. 12, the ground metal fitting 29, which is a single metal piece, short-circuits the conductive metal fitting 17 and the installation rail 2, but the ground metal fitting 29 contacts the installation rail 2. Instead, the ground metal fitting 29 and the installation rail 2 may be electrically connected via the pinching metal fitting 26. In such a configuration, since the conductive metal member 17 and the installation rail 2 are short-circuited by the two members of the ground metal member 29 and the pinch metal fitting 26, the pinch metal fitting 26 is included in the earth metal fitting according to the present invention. . Similarly, in the second embodiment, the earth metal fitting 29 and the pedestal 50 may be electrically connected using the metal fixing screw 27 without bringing the earth metal fitting 29 into contact with the pedestal 50. In such a configuration, since the conductive metal member 17 and the base 50 are short-circuited by the two members of the ground metal member 29 and the fixing screw 27, the fixing screw 27 is included in the ground metal member according to the present invention.
