Description
この発明は、電線端子を端子盤において端子金物と接続する際に、電気的接続を確実にし、接続抵抗の発生又は発熱など接続不良を皆無にすると共に、端子盤を使用中に接続不良を生じないようにすることを目的としたものである。 This invention ensures the electrical connection when connecting the wire terminal to the terminal hardware in the terminal board, eliminates connection failure such as generation of connection resistance or heat generation, and causes connection failure while using the terminal board. The purpose is to avoid.
従来端子盤には複数の端子金具が固定され、夫々の端子金具の一端部に夫々入力電線を接続し、前記端子金具の他端を、電気機器の入力部へ挿入接続している。前記入力電線の接続部には通常接続端子が固定されていて、入力電線と、端子金具の一端とは、接続端子により確実に接続されている。然し乍ら入力電線端に接続端子が固定してない場合には、通常絶縁被覆を除去した複数の細線を端子金具へ加圧締付固定して接続している。
従来電線は通常複数の細線を捩り合せて一本の太線とし、その外側へ絶縁被覆を施している。従って、電線端に接続端子が固定してない場合には、複数の細線がばらばらになっている電線端部を、金具の平板面と、締付ボルトの座板の平板面とで挟着することになるので、往々細線の外面に、座板の平面が接線状に当接することになり、接触面積が少ない為に発熱を生じたり、振動などにより当接部がずれ又は緩むと、接触不良又は当接部間へ他物(微小異物)が付着するおそれがあるなど、往々接触不良を生じる問題点があった。 Conventional electric wires usually twist a plurality of thin wires into a single thick wire, and an insulating coating is applied to the outside thereof. Therefore, when the connection terminal is not fixed to the end of the electric wire, the end of the electric wire in which a plurality of thin wires are separated is sandwiched between the flat surface of the metal fitting and the flat surface of the seat plate of the tightening bolt. As a result, the flat surface of the seat plate often comes into contact with the outer surface of the thin wire. If the contact area is small and heat is generated, or if the contact part is displaced or loosened due to vibration, contact failure In addition, there is a problem that a contact failure often occurs such that there is a possibility that another object (a minute foreign matter) may adhere between the contact parts.
また接触面積が少ない為に、引抜抵抗力が小さくなり、不慮の外力によって接続電線がずれて接触不良を生じる問題点があった。 In addition, since the contact area is small, the pulling resistance force is reduced, and there is a problem that the connection electric wire is displaced due to an unexpected external force, resulting in a contact failure.
この発明は、端子金具部の受け座板と、締付ボルトの押え座板の何れか一方又は両方に複数の電線の当接面を設けることにより、電線と座板との接触面積を増加させ、前記従来の問題点を解決したのである。 The present invention increases the contact area between the electric wire and the seat plate by providing a contact surface for a plurality of electric wires on one or both of the receiving seat plate of the terminal metal part and the holding seat plate of the clamping bolt. The conventional problems have been solved.
即ちこの発明は、
絶縁材製の端子台に固定する端子金具の受け座板と、これに対向する押え座板とにより電線の裸線を挟着し、ボルトで締付けて、端子金具と、電線とを電気的に接続する端子盤における電線端部の接続装置であって、
前記端子金具は、受け座板の上側に端子片が屈曲して連結されているものであって、受け座板は、受け座板側のボルト孔を備えていると共に、受け座板の前記押え座板に対向する側の面の、当該受け座板側のボルト孔の両側に上下方向に延びる断面弧状の凹入部を備えていて、

前記押え座板における前記突条は、前記押え座板の前記受け座板に対向する側の面における、前記受け座板と前記押え座板とで電線の裸線を挟着する際に前記受け座板の断面弧状の凹入部に対向する部分には形成されておらず、

また入力電線に通常の接続端子を連結した場合にも、前記座板が使用できることが好ましいが、同一使用態様の場合には、入力電線の裸線専用に、より適切な断面形状とすることを妨げない。 In addition, it is preferable that the seat plate can be used even when a normal connection terminal is connected to the input electric wire. However, in the case of the same usage mode, a more appropriate cross-sectional shape should be used exclusively for the bare wire of the input electric wire. I do not disturb.
この発明によれば、端子金具の受け座板と、ボルトの押え座板の断面形状を工夫し、裸電線との接触面積を大きくしたので、入力電線の接続を正確かつ確実にし、外力によって接触不良を生じないようにした効果がある。 According to the present invention, the cross-sectional shape of the receiving plate of the terminal fitting and the holding plate of the bolt is devised, and the contact area with the bare wire is increased, so that the connection of the input wire is made accurate and reliable, and contact is made by external force. This has the effect of preventing defects.
