## Abstract

An electrical apparatus disclosed herein includes first/second electrical units configured to be fixed to each other. The first electrical unit has a first surface including a connector. The second electrical unit has a second surface facing the first surface of the first electrical unit. The second surface includes a socket configured to fit with the connector. One of the first and second electrical units includes a stud bolt extending toward the other of the first electrical unit and the second electrical unit, and the other of the first and second electrical units includes a bolt hole through which the stud bolt is configured to pass. When the second electrical unit is separated from the first electrical unit with the second surface facing the first surface, a bolt-hole distance from the stud bolt to the bolt hole is shorter than a connector-socket distance from the connector to the socket.

## Claims

### Claim 1

An electrical apparatus comprising:
a first electrical unit having a first surface comprising a connector; and
a second electrical unit configured to be fixed to the first electrical unit and having a second surface comprising a socket configured to fit with the connector, the second surface facing the first surface,
wherein one of the first electrical unit and the second electrical unit comprises a stud bolt extending toward the other of the first electrical unit and the second electrical unit, and
the other of the first electrical unit and the second electrical unit comprises a bolt hole through which the stud bolt is configured to pass,
wherein, when the second electrical unit is separated from the first electrical unit with the second surface facing the first surface, a bolt-hole distance from the stud bolt to the bolt hole is shorter than a connector-socket distance from the connector to the socket, wherein
the connector includes a tip portion and a base portion, wherein an outer diameter of the base portion is greater than an outer diameter of the tip portion, and
when the second electrical unit is separated from the first electrical unit with the second surface facing the first surface, the pin-hole distance is longer than the connector-socket distance but shorter than a distance from a boundary between the tip portion and the base portion to the socket.

### Claim 2

An electrical apparatus comprising:
a first electrical unit having a first surface comprising a connector; and
a second electrical unit configured to be fixed to the first electrical unit and having a second surface comprising a socket configured to fit with the connector, the second surface facing the first surface,
wherein one of the first electrical unit and the second electrical unit comprises a stud bolt extending toward the other of the first electrical unit and the second electrical unit, and
the other of the first electrical unit and the second electrical unit comprises a bolt hole through which the stud bolt is configured to pass,
wherein, when the second electrical unit is separated from the first electrical unit with the second surface facing the first surface, a bolt-hole distance from the stud bolt to the bolt hole is shorter than a connector-socket distance from the connector to the socket, wherein
one of the first electrical unit and the second electrical unit comprises a positioning pin extending toward the other of the first electrical unit and the second electrical unit, and
the other of the first electrical unit and the second electrical unit comprises a positioning hole through which the positioning pin is configured to pass,
wherein
a clearance between the positioning pin and the positioning hole is smaller than a clearance between the stud bolt and the bolt hole, and
when the second electrical unit is separated from the first electrical unit with the second surface facing the first surface, a pin-hole distance from the positioning pin to the positioning hole is longer than the bolt-hole distance but shorter than the connector-socket distance, wherein
the socket includes a tip portion and a base portion, wherein an inner diameter of the base portion is smaller than an inner diameter of the tip portion, and
when the second electrical unit is separated from the first electrical unit with the second surface facing the first surface, the pin-hole distance is longer than the connector-socket distance but shorter than a distance from a boundary between the tip portion and the base portion to the connector.
