Abstract

A terminal block includes a base, a support provided on the support, and a first terminal pair, a second terminal pair and a third terminal pair each supported by the support. A coupling line of the first electric wire is arranged along a first straight line, and a coupling line of the second electric wire is arranged along a second straight line. The base includes a support protrusion that extends to a coupling line of the third electric wire through between the coupling line of the first electric wire and the coupling line of the second electric wire and supports the coupling line of the third electric wire.

First claim

The invention claimed is:

1. A terminal block comprising:
an insulating base including an installation surface;
an insulating support provided on the installation surface; and
a first terminal pair, a second terminal pair, and a third terminal pair each supported by the support, wherein
each of the first terminal pair, the second terminal pair, and the third terminal pair includes a first connection terminal and a second connection terminal, the first connection terminal and the second connection terminal of the first terminal pair are electrically connected to each other by a first electric wire, the first connection terminal and the second connection terminal of the second terminal pair are electrically connected to each other by a second electric wire, and the first connection terminal and the second connection terminal of the third terminal pair are electrically connected to each other by a third electric wire,
the first connection terminal of the first terminal pair, the first connection terminal of the second terminal pair, the first connection terminal of the third terminal pair, the second connection terminal of the third terminal pair, the second connection terminal of the first terminal pair, and the second connection terminal of the second terminal pair are arranged in this order in a first direction along the installation surface,
the first terminal pair, the second terminal pair, and the third terminal pair are arranged electrically independently of each other,
the first connection terminal of the first terminal pair, the first connection terminal of the second terminal pair, and the first connection terminal of the third terminal pair are arranged in a stepwise manner so as to be farther from the installation surface in a second direction intersecting the installation surface from the first connection terminal of the first terminal pair toward the first connection terminal of the third terminal pair,
each of the first electric wire, the second electric wire, and the third electric wire includes a first connection line extending in the second direction and connected to the first connection terminal, a second connection line extending in the second direction and connected to the second connection terminal, and a coupling line arranged in an electric wire passage portion provided between the base and the support in the second direction and extending in the first direction to couple the first connection line and the second connection line to each other,
the coupling line of the first electric wire is arranged along a first straight line extending in the first direction, and the coupling line of the second electric wire is arranged along a second straight line arranged at an interval from the first straight line in a third direction intersecting the first direction and the second direction,
the coupling line of the second electric wire is arranged between the coupling line of the first electric wire and the coupling line of the third electric wire, and the coupling line of the first electric wire is arranged closer to the installation surface than the coupling line of the third electric wire in the second direction, and
the base includes a support protrusion that extends from the installation surface to the coupling line of the third electric wire through between the coupling line of the first electric wire and the coupling line of the second electric wire, and that supports the coupling line of the third electric wire.

2. The terminal block according to claim 1 , wherein
the support includes an insulating first cover wall portion arranged in the electric wire passage portion, the first cover wall portion surrounding the second connection line of the first electric wire.

3. The terminal block according to claim 1 , wherein
the support includes an insulating second cover wall portion arranged in the electric wire passage portion, the second cover wall portion surrounding the end portion of the coupling line of the third electric wire on the second connection line side and extending to the coupling line of the second electric wire in the second direction.

4. The terminal block according to claim 1 , wherein
each of the first electric wire, the second electric wire, and the third electric wire has a rod shape.

5. The terminal block according to claim 1 , wherein
the coupling line of the third electric wire includes an end portion on a first connection line side arranged on the first straight line and an end portion on a second connection line side arranged on the second straight line, and extends in a direction intersecting the first straight line and the second straight line.

6. The terminal block according to claim 5 , wherein
the support protrusion includes a protruding portion that supports the coupling line of the second electric wire, in addition to the coupling line of the third electric wire.
