Abstract

A terminal block device to which a first wire and a second wire are to be connected includes a terminal block body made of an insulating material, a cover that is made of an insulating material and covers the terminal block body, a shaft member at which a terminal of the first wire and a terminal of the second wire are engaged, a cylindrical relay terminal through which the shaft member is inserted and which is inserted through the cover, a fastening member for fastening the terminal of the first wire and the terminal of the second wire to the relay terminal. The relay terminal includes a first seat surface that is contactable with the terminal of the first wire between the terminal block body and the cover and a second seat surface that is contactable with the terminal of the second wire outside the cover.

First claim

What is claimed is:

1. A terminal block device comprising:
a terminal block body made of an insulating material;
a cover that is made of an insulating material and covers the terminal block body;
a shaft member that is held by the terminal block body to engage a terminal of a first wire and a terminal of a second wire;
a cylindrical relay terminal through which the shaft member is inserted and which is inserted through the cover; and
a fastening member that is mounted on the shaft member to fasten the terminal of the first wire and the terminal of the second wire to the relay terminal, wherein
the relay terminal includes a first seat surface that is contactable with the terminal of the first wire between the terminal block body and the cover and a second seat surface that is contactable with the terminal of the second wire outside the cover.

2. The terminal block device according to claim 1 , wherein
the number of the first wires is plural,
the number of the second wires is plural,
the cover includes an inner wall surface that faces the terminal block body,
the terminal block body includes an opposing surface that faces the inner wall surface, and
an insulating partition that extends from at least one of the inner wall surface and the opposing surface and provides insulation between two adjacent ones of the wires.

3. The terminal block device according to claim 1 , wherein
the cover has an insertion hole through which the relay terminal is inserted, and a retainer that is mounted to the relay terminal and prevents the relay terminal from being slipped off from the insertion hole of the cover.

4. The terminal block device according to claim 3 , wherein
an annular seal member is mounted to an outer periphery of the relay terminal, and
the seal member provides sealing in the insertion hole between the relay terminal and the cover.

5. A terminal block device to be fixed to a base and electrically connected to one end of a first wire and one end of a second wire, wherein the base houses the other end of the first wire, and wherein the first wire includes a bent portion and a terminal-side portion that extends from the bent portion to the one end of the first wire, comprising:
a terminal block that is made of an insulating material;
a terminal portion that is mounted to the terminal block; and
a partition plate that extends from the terminal block perpendicularly to a direction in which the terminal-side portion extends, wherein
the partition plate is interposed between the other end of the first wire and the base after the terminal block is fixed to the base.

6. The terminal block device according to claim 5 , wherein
the terminal block includes a terminal block body to be fixed to the base and a cover that covers the terminal block body,
the terminal block body has an opening through which the first wire is inserted, and
the partition plate extends from the terminal block body.

7. The terminal block device according to claim 5 , wherein
the partition plate is a first partition plate,
a second partition plate extends from the terminal block parallel to a plane in which the first wire extends, and
the second partition plate is interposed between the other end of the first wire and the base after the terminal block is fixed to the base.

8. The terminal block device according to claim 5 , wherein
the first wire is connected from an electric motor to the terminal block, and
the second wire is connected from the terminal block to an external device.
