CONNECTION UNIT

摘要

The present invention provides a connection unit capable of accommodating nuts and showing sealing ability in a state installed on a housing.;A connection unit S includes: a terminal block 100 having holes h3 at one side of for accommodating nuts n; a terminal-connecting portions 200 at least partially exposed when viewed from the other side and fixed to the terminal block 100 with the circumferences of the terminal-connecting portions 200 in tight contact with the terminal block 100; and a nut cover 300 for covering the nuts accommodated in the holes h3 for preventing the nuts n from coming off. The connection unit S further includes: guide grooves and guide ribs for restricting movement of the nut cover 300 relative to the terminal block 100; and locking hooks 116 and locking holes h5 for restricting movement of the nut cover 300 relative to the terminal block 100.

1. A connection unit comprising:
a terminal block formed with a nut-accommodating portion that is open at at least one side of the terminal block and that is adapted for accommodating a nut; a terminal-connecting portion that is at least partially exposed when viewed from another side and is fixed to the terminal block in such a way that a circumference of the terminal-connecting portion is in tight contact with the terminal block; and a nut cover for covering the nut accommodated in the nut-accommodating portion to prevent the nut from coming off the accommodating portion, the connection unit being fitted on a housing that houses a power unit, the connection unit being adapted to sandwich the terminal-connecting portion and an external terminal that is connected to the power unit, between a head of a bolt inserted from the other side and the nut accommodated in the nut-accommodating portion, for electrically connecting the terminal-connecting portion to the external terminal, the connection unit further comprising: a first restricting means for restricting a movement of the nut cover relative to the terminal block both in an axial direction of the bolt and in a first direction perpendicular to the axial direction; and a second restricting means for restricting a movement of the nut cover relative the terminal block in a second direction perpendicular both to the axial direction and to the first direction, the second restricting means including: a locking hook formed on one of the terminal block and the nut cover; and a locking hole formed in the other one of the terminal block and the nut cover, the locking hole being adapted to receive the locking hook.
