WIRE CONNECTION STRUCTURE AND DISTRIBUTION BOARD

To provide a wire connection structure capable of improving efficiency of connection work of an electric wire and preventing a mistake in distribution of an electric wire.SOLUTION: A wire connection structure includes: a first conductor 5a; a second conductor 5b; and a quick connection terminal unit 6. The quick connection unit 6 includes: an electric wire insertion hole 63 formed on a front surface side X1 of a housing 60; a quick connection terminal part 62 which is electrically connected to an electric wire S inserted in the electric wire insertion hole 63 and which is constructed to allow the electric wire S to be inserted into and extracted from it; and a connection terminal 61 electrically connected to the quick connection terminal part 62 and exposed to a back surface side X2 of the housing 60. The quick connection terminal unit 6 is constructed so that the quick connection terminal unit 6 is attachable to the first conductor 5a or the second conductor 5b in a first orientation p1 in which the connection terminal 61 is in conduction to the first conductor 5 and is not in conduction to the second conductor 5b, and is constructed so that the quick connection terminal unit 6 is attachable to the first conductor 5a or the second conductor 5b in a second orientation p2 in which the connection terminal 61 is in conduction to the second conductor 5b and is not in conduction to the first conductor 5a.SELECTED DRAWING: Figure 5A 【課題】電線の接続作業の効率を向上させることができ、更に、電線の配線ミスを防止可能な電線接続構造を提供する。【解決手段】電線接続構造は、第１導体５ａ、第２導体５ｂ、速結端子ユニット６を有する。速結端子ユニット６は、筐体６０の正面側Ｘ１に形成された電線挿通孔６３と、電線挿通孔６３に挿入された電線Ｓと電気的に接続され、電線Ｓの挿抜が自在に構成された速結端子部６２と、速結端子部６２に電気的に接続され且つ筐体６０の背面側Ｘ２に露出する接続用端子６１と、を有する。速結端子ユニット６は、接続用端子６１が第１導体５ａに導通し且つ第２導体５ｂに導通しない第１の向きｐ１で第１導体５ａ又は第２導体５ｂに取り付け可能に構成され、且つ、接続用端子６１が第２導体５ｂに導通し且つ第１導体５ａに導通しない第２の向きｐ２で第１導体５ａ又は第２導体５ｂに取り付け可能に構成されている。【選択図】図５Ａ
