TERMINAL BLOCK

PROBLEM TO BE SOLVED: To provide a terminal block which easily visually recognizes a display terminal part and is capable of suppressing erroneous recognition as further as possible, the terminal block comprising the display terminal part for notifying a user of whether insertion of a lead wire is appropriate.SOLUTION: A lead wire insertion mechanism 40 consisting of an elastic stick part 51 including a pressure receiving protrusion 53 positioned in a lower part of a lead wire insertion path 18, a tilting stick part 42 including a display terminal part 45 in an upper end and a coupling stick part 52 connecting the elastic stick part 51 and the tilting stick part 42 is disposed on an insulative substrate 2. Therefore, in a non-mounting state of a lead wire, the pressure receiving protrusion 53 is held at an ordinary position P and the display terminal part 45 is held at an exposure position Q. When an insertion end of the lead wire is inserted to a connection position, on the other hand, the pressure receiving protrusion 53 is extruded outsides by the insertion end and the coupling stick part 52 is pulled outsides, thereby the tilt stick part 42 is tilted, and the display terminal part 45 is moved from the exposure position Q to a retraction position R.SELECTED DRAWING: Figure 8 【課題】リード線の挿入が適切であるか否かを報知する表示端部を備えたものであって、該表示端部を視認し易く、かつ誤認を可及的に抑制し得る端子台を提供する。【解決手段】リード線挿入路１８の下部に位置する受圧突部５３を備えた弾性杆部５１と、上端に表示端部４５を備えた傾動杆部４２と、該弾性杆部５１と傾動杆部４２とを結ぶ連係杆部５２とで構成されるリード線挿入機構４０を、絶縁性基板２に配設されたものであるから、リード線の非装着状態で、受圧突部５３が定常位置Ｐで保持され且つ表示端部４５が表出位置Ｑで保持される一方、リード線の挿入端を接続位置まで挿入すると、該挿入端により受圧突部５３が外方へ押し出されて、連係杆部５２が外方へ引っ張られることで傾動杆部４２が傾動し、表示端部４５が表出位置Ｑから退避位置Ｒへ移動する。【選択図】図８
