TERMINAL BLOCK FOR ELECTRIC MOTOR, ELECTRIC MOTOR, BLOWER, AND CONNECTION METHOD OF TERMINAL PIN AND CONNECTION TERMINAL

PROBLEM TO BE SOLVED: To provide a terminal block for electric motor etc. capable of improving the quality of dissimilar metal junction while reducing the number of process steps.SOLUTION: There is provide a terminal block 1 for electric motor which includes: a mortar-shaped concave 2 having a reverse hollow conical shape with bottom 24 in which a through hole 11 for allowing a terminal pin 7 with a tied wiring 8 to pass therethrough; a synthetic resin injection groove 4 which is formed up to the side face of the concave 2 from a position away from the central axis of the concave 2 farther than the edge thereof in an opening top 3 of the concave 2; and a filling amount check groove 6 which is formed up to the opposite side face, which is the side face of the concave 2 at the opposite start side, from a start point 26 of the synthetic resin injection groove 4 at the opposite position being interposed by the central axis.SELECTED DRAWING: Figure 4 【課題】異種金属接合部の品質向上と工程工数低減を可能とする、電動機用端子台等を提供する。【解決手段】巻線８が絡げられた端子ピン７を貫通するための貫通孔１１を底面２４に設けた逆中空円錐形状のすり鉢形状凹部２と、前記凹部２開口天面３における端部よりもさらに前記凹部２の中心軸から離れた位置を起点として前記凹部２の側面まで掘り込まれた合成樹脂注入溝４と、前記合成樹脂注入溝４の起点２６から前記中心軸を挟んで対向位置を対向起点として前記凹部２において前記対向起点側の側面である逆側面まで掘り込まれた充填量確認溝６を備えた電動機用端子台１を提供する。【選択図】図４
