Abstract

An electrical device connector includes: a bus bar which includes a hollow portion extending in an axial direction and through holes extending in an axis-orthogonal direction, and which electrically connects a plurality of switchgears to each other; terminal members including bus bar support portions in which the bus bar is inserted, and including electrical device connection portions in which the insulation plugs are inserted and fixed; and stud bolts 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 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 of the corresponding terminal member.

First claim

The invention claimed is:

1. An electrical device connector comprising:
a bus conductor including a hollow portion extending in an axial direction and through holes extending in an axis-orthogonal direction orthogonal to the axial direction, the bus conductor being configured to electrically connect a plurality of switchgears to each other;
insulation plugs each having one end connected to an electrical device which is connected to the bus conductor, the insulation plugs each being configured to electrically insulate the electrical device and the bus conductor;
terminal members each including a bus conductor support portion which has a hollow cylindrical shape extending in the axial direction and in which the bus conductor is inserted, the terminal members each further including an electrical device connection portion which extends in the axis-orthogonal direction and in which a corresponding one of the insulation plugs is inserted and fixed; and
fixing members each having one end fixed to a corresponding one of the switchgears and each extending in the axis-orthogonal direction through a corresponding one of the through holes, the fixing members each having another end fixed to the corresponding one of insulation plugs,
wherein gaps are each formed between a corresponding one of the fixing members and the bus conductor so as to allow communication between the hollow portion and an internal space of a corresponding one of the terminal members.

2. The electrical device connector according to claim 1 wherein each through hole has a diameter not less than twice a diameter of the corresponding one of the fixing members.

3. The electrical device connector according to claim 2 wherein
the terminal members are formed from silicone rubber.

4. The electrical device connector according to claim 2 wherein
the terminal members are formed from fluororubber or ethylene propylene rubber.
