As shown in FIG. 1, the electrical equipment storage box according to the present embodiment has two conductive bars 2 fixedly disposed along a wall surface 5 in the housing 1. In addition, a device mounting hole 18 for sliding and mounting the electrical device 3 is provided on one side of the bottom surface of the housing 1, and a terminal portion and a wiring hole 17 are provided on the other side. As the terminal portion, a power supply line connecting portion 12 of the conductive bar 2 to be described later and a power supply line (not shown) are connected, and an incoming terminal block 10 which is a fixing portion for fixing the conductive bar, and a ground terminal portion 19 are provided. did. A wiring hole 17 formed between the incoming terminal portion 15 and the ground terminal portion 16 is used for incoming and outgoing power lines (not shown).
図２に示すように、この筺体１内に収納される電気機器３には、この導電バー２にプラグイン接続される凹状端子部４が形成されている。電気機器３を筐体１内に収納する作業は、この凹状端子部４に導電バー２を差し込むだけの簡単な作業で完了することができる。本発明において、電気機器３の種類は特に限定されず、ブレーカ、避雷器、通信装置、計測装置など任意の電気機器を収納する電気機器収納用箱に適用することができる。 As shown in FIG. 2, the electrical device 3 housed in the housing 1 is formed with a concave terminal portion 4 that is plugged into the conductive bar 2. The operation of housing the electrical device 3 in the housing 1 can be completed by a simple operation of simply inserting the conductive bar 2 into the concave terminal portion 4. In the present invention, the type of the electric device 3 is not particularly limited, and can be applied to an electric device storage box that stores any electric device such as a breaker, a lightning arrester, a communication device, and a measuring device.
電気機器３は、この導電バー２の一側部６から挿入される。電気機器３の挿入時、導電バー２に対しても、その挿入方向に力が加わるが、本実施形態では、導電バー２の他側部７と当接する当接部８を、筺体１に備えているため、この当接部８でその力を受けることができ、この力に起因する導電バー２の回転を防止することができる。
また、このような構成を採用することにより、従来技術のように、導電バー２の両側にバーホルダ等の固定部材を使用することなく、導電バー２を筐体内に固定配置することで、筺体１のコンパクト化を図ることができる。
The electric device 3 is inserted from one side 6 of the conductive bar 2. When the electric device 3 is inserted, a force is also applied to the conductive bar 2 in the insertion direction. However, in the present embodiment, the housing 1 is provided with a contact portion 8 that contacts the other side portion 7 of the conductive bar 2. Therefore, the force can be received by the contact portion 8, and the rotation of the conductive bar 2 due to this force can be prevented.
In addition, by adopting such a configuration, the conductive bar 2 is fixedly arranged in the housing without using fixing members such as a bar holder on both sides of the conductive bar 2 as in the prior art, so that the housing 1 Can be made compact.
また、本実施形態では、電気機器３を引き抜く際の導電バー２の回転防止の為に、導電バー２を端子の片側に形成した当接壁１５に当接させている。当接壁１５により電気機器３の引抜時の力を受けることで、導電バー２の回転を防止することができる。 Moreover, in this embodiment, in order to prevent rotation of the conductive bar 2 when the electric device 3 is pulled out, the conductive bar 2 is brought into contact with the contact wall 15 formed on one side of the terminal. By receiving the force when the electric device 3 is pulled out by the contact wall 15, the rotation of the conductive bar 2 can be prevented.
本実施形態では、当接部８として、筐体１の壁面５に凸状部分を形成している。その他の実施形態として、筐体１の壁面５に凸状部分を設けず、フラットな状態のまま当接部８として利用したり、壁面５に薄板状の当接部材を重ねて当接部８とすることもできる。 In the present embodiment, a convex portion is formed on the wall surface 5 of the housing 1 as the contact portion 8. As other embodiments, the wall surface 5 of the housing 1 is not provided with a convex portion and is used as the contact portion 8 in a flat state, or a thin plate contact member is stacked on the wall surface 5 to contact the contact portion 8. It can also be.
図２及び図３のように、導電バー２は、筐体１内でその壁面５に沿って配置することにより、導電バー２と壁面５間に余剰なスペースを生むことなく、筺体１内を有効に活用することができる。また、それぞれの導電バー２は、同一の略Ｌ字形状（筺体の底面と平行面への投影上で、略９０°の角度を有するＬ字形状）を有し、長辺部分を、電気機器３の凹状端子部４とプラグイン接続されるプラグイン挿入部９として使用し、短辺部分を、配線孔１７から入線した電源線を接続する電源線接続部１２として使用している。また、導電バー２の略Ｌ字角部には、導電バー２を入線用端子台１０に固定するためのバー固定ネジ１６を設けるものとした。本実施形態では、各極の接続位置に段差を設けた入線用端子台１０を使用し、２極分の導電バー２のプラグイン挿入部９部分が上下に積層するように配置されているが、前記のように、それぞれの導電バー２を同一の略Ｌ字形状に形成しているため、導電バー２を筐体内に省スペースで配置することができるとともに、電源線接続部１２を、筺体の底面と平行面への投影上で、各々ずらして配置することができ、電源線接続部１２において容易に電源線を接続することができるものとなる。なお、固定部は筐体と一体に成型されてもよいし、別体の端子台を筐体に固定するものであってもよいものとする。 As shown in FIGS. 2 and 3, the conductive bar 2 is disposed along the wall surface 5 in the housing 1, so that the interior of the housing 1 can be formed without creating an excessive space between the conductive bar 2 and the wall surface 5. It can be used effectively. In addition, each conductive bar 2 has the same substantially L shape (L shape having an angle of approximately 90 ° on the projection onto the plane parallel to the bottom surface of the housing), and the long side portion is connected to the electric device. 3 is used as a plug-in insertion portion 9 that is plug-in connected to the concave terminal portion 4, and the short side portion is used as a power supply line connecting portion 12 that connects a power supply line that is inserted from the wiring hole 17. Further, a bar fixing screw 16 for fixing the conductive bar 2 to the incoming terminal block 10 is provided at a substantially L-shaped corner of the conductive bar 2. In this embodiment, the incoming terminal block 10 provided with a step at the connection position of each pole is used, and the plug-in insertion portion 9 portion of the conductive bar 2 for two poles is arranged so as to be stacked vertically. As described above, since the respective conductive bars 2 are formed in the same substantially L shape, the conductive bars 2 can be disposed in a space-saving manner in the casing, and the power line connecting portion 12 is provided with a housing. The projections on the bottom and parallel planes can be shifted from each other, and the power supply line connecting portion 12 can easily connect the power supply lines. The fixing portion may be molded integrally with the housing, or may be a member that fixes a separate terminal block to the housing.
なお、導電バー２の形状は、上記構造に限定されず、例えば、図３に示すように、略Ｌ字に配置されたプラグイン挿入部９と電源線接続部１２との高さに段差が形成されるように、プラグイン挿入部９と電源線接続部１２の接合部分に段差部１３を形成した構造として、段差のない入線用端子台１０との組み合わせで使用することもできる。段差のない入線用端子台１０とすることで、電源線接続部１２のネジを締付けるためのドライバーを容易に端子ネジにアクセスすることができる。また、何れの形態においても各導電バー２のプラグイン挿入部９の電源線接続部１２の反対側に延びる端部を同一位置で揃えたものとしてもよい。そうすれば、電気機器３を、電気機器３の各極の端子部の配置に関係なく導電バー２に接続することができる。 The shape of the conductive bar 2 is not limited to the above structure. For example, as shown in FIG. 3, there is a step in the height between the plug-in insertion portion 9 and the power supply line connection portion 12 arranged in a substantially L shape. As a structure in which the stepped portion 13 is formed at the joint portion between the plug-in insertion portion 9 and the power supply line connecting portion 12 as formed, it can be used in combination with the incoming terminal block 10 having no step. By using the incoming terminal block 10 without a step, a driver for tightening the screw of the power line connecting portion 12 can easily access the terminal screw. Moreover, in any form, it is good also as what aligned the edge part extended on the opposite side of the power source line connection part 12 of the plug-in insertion part 9 of each electrically-conductive bar 2 in the same position. If it does so, the electric equipment 3 can be connected to the electrically-conductive bar 2 irrespective of arrangement | positioning of the terminal part of each pole of the electric equipment 3.
