ELECTRICAL-DEVICE CONNECTING APPARATUS AND OPENING/CLOSING APPARATUS

An object of the present invention is to obtain an electrical device connector that enables easy and effective deaeration of electrical device connection portions, and switchgears. An electrical device connector (100) includes: a bus bar (10) which includes a hollow portion (13) extending in an axial direction and through holes (14) extending in an axis-orthogonal direction, and which electrically connects a plurality of switchgears (91) to each other; insulation plugs (20) which each electrically insulate the bus bar and an instrument voltage transformer (92) connected to the bus bar; terminal members (30 and 40) including bus bar support portions (31 and 41) which each have a hollow cylindrical shape extending in the axial direction and in which the bus bar is inserted, and including electrical device connection portions (32 and 42) which extend in the axis-orthogonal direction and in which the insulation plugs are inserted and fixed; and stud bolts (50) each having one end fixed to the corresponding switchgear, each extending in the axis-orthogonal direction through the corresponding through hole, and each fixing the corresponding insulation plug at the other end. Gaps (81) are each formed between the corresponding stud bolt and the bus bar so as to allow communication between the hollow portion and an internal space (X) of the corresponding terminal member.
