Abstract

A terminal block includes: a terminal body with a screw hole for a screw used to connect a wire; and a terminal holder that holds the terminal body and has a substrate facing portion placed facing a first surface of a substrate. The terminal block is attached to the substrate by soldering the terminal body to a conductive pattern of the substrate with the substrate facing portion facing the first surface. The terminal holder has the substrate facing portion at one end in a first direction that becomes parallel to the thickness of the substrate when the terminal block is attached to the substrate. A casing fixing portion equipped with an insertion portion, into which a fastener for fixing the terminal holder to a casing that houses the substrate is inserted, is provided at another end in the first direction of the terminal holder.

First claim

What is claimed is:

1. A terminal block comprising:
a terminal body equipped with a screw hole into which a connecting screw is capable of being screwed to connect a connecting wire; and
a terminal holding portion equipped with a substrate facing portion placed facing a first surface of an attached substrate and configured so as to be capable of holding the terminal body,
wherein the terminal block is configured so as to be capable of being attached to the attached substrate by soldering the terminal body to a conductive pattern of the attached substrate in a state where the substrate facing portion has been placed facing the first surface,
the terminal holding portion is provided with the substrate facing portion at one end in a first direction that becomes parallel to a thickness direction of the attached substrate when the terminal block is attached to the attached substrate, and
a casing fixing portion equipped with an insertion portion, into which a fastening member for fixing the terminal holding portion to a casing capable of housing the attached substrate is inserted, is provided at another end in the first direction of the terminal holding portion.

2. The terminal block according to claim 1 ,
wherein the terminal body is configured so that the connecting screw is capable of being screwed into the screw hole in at least one direction out of the first direction and a second direction that becomes parallel to the first surface when the terminal block is attached to the attached substrate, and
the terminal holding portion is configured so that when looking along the second direction, the casing fixing portion is positioned within a width range from one end of the terminal body in a third direction that intersects both the first direction and the second direction and another end of the terminal body in the third direction.

3. The terminal block according to claim 1 ,
wherein the terminal body is equipped with at least three soldered portions that are inserted through terminal insertion through-holes provided in the attached substrate and are soldered to the conductive pattern, and the soldered portions are disposed so that when looking along the first direction, at least one soldered portion out of the soldered portions is not positioned on a virtual straight line that joins positions of another two out of the soldered portions.

4. The terminal block according to claim 2 ,
wherein the terminal body is equipped with at least three soldered portions that are inserted through terminal insertion through-holes provided in the attached substrate and are soldered to the conductive pattern, and the soldered portions are disposed so that when looking along the first direction, at least one soldered portion out of the soldered portions is not positioned on a virtual straight line that joins positions of another two out of the soldered portions.

5. An electronic appliance comprising the terminal block according to claim 1 ,
wherein the terminal block is attached to the attached substrate, the attached substrate is housed in the casing, and the terminal block is fixed to the casing.

6. An electronic appliance comprising the terminal block according to claim 2 ,
wherein the terminal block is attached to the attached substrate, the attached substrate is housed in the casing, and the terminal block is fixed to the casing.

7. An electronic appliance comprising the terminal block according to claim 3 ,
wherein the terminal block is attached to the attached substrate, the attached substrate is housed in the casing, and the terminal block is fixed to the casing.

8. An electronic appliance comprising the terminal block according to claim 4 ,
wherein the terminal block is attached to the attached substrate, the attached substrate is housed in the casing, and the terminal block is fixed to the casing.
