## Abstract

A board connector includes: an L-shaped pin terminal including an insertion inserted into a through hole in a printed board and a conductor swaging part extending in a direction (+Y-axis direction) orthogonal to the insertion; and a housing disposed on one main surface (flat face on the +Z side) of the printed board, the housing containing at least an end of the conductor swaging part and having an opening into which a cable connected to the conductor swaging part is inserted. The board connector further includes a J-shaped boss formed integrally with the housing, the boss passing through a through hole in the printed board and protruding from another main surface (flat face on the −Z side) of the printed board, extending in a direction (D2) (the +Y-axis direction) opposite to a direction toward the insertion, and further extending toward the printed board.

## Claims

### Claim 1

A board connector for attachment to a board that includes a first through hole and a second through hole, the board connector comprising:
an L-shaped pin terminal comprising an insertion inserted into the first through hole and a connecting part extending in a direction orthogonal to the insertion;
a housing disposed on one main surface of the board, the housing containing at least an end of the connecting part and having an opening into which a cable connected to the connecting part is inserted; and
a J-shaped boss formed integrally with the housing, the boss passing through the second through hole and protruding from an other main surface of the board, extending from an end of the housing that is apart from the pin terminal and in a direction opposite to the direction toward the insertion, and further extending toward the board wherein
the boss comprises:
a base contiguous to the housing and inserted into the second through hole;
a protrusion contiguous to the base and protruding from the other main surface of the board;
an inversion contiguous to the protrusion, the inversion extending in the direction opposite to the direction toward the pin terminal and being inverted toward the board; and
an end contiguous to the inversion and extending toward the board,
a space is formed between the protrusion and the end, and
the inversion and the end protrude from an end of the housing that is apart from the pin terminal and in a direction opposite to the direction toward the pin terminal (+Y direction).

### Claim 2 (depends on 1)

The board connector according to claim 1, wherein the end is formed such that a thickness of the end in the opposite direction decreases as the end is closer to the inversion.

### Claim 3 (depends on 1)

The board connector according to claim 1, wherein the boss is disposed at an end of the housing on a side of a direction in which the connecting part extends.

### Claim 4 (depends on 1)

The board connector according to claim 1, wherein a plurality of the pin terminals are disposed to be spaced apart from one another along a direction that is orthogonal to the insertion and is orthogonal to the connecting part, and wherein a plurality of the bosses are disposed to be spaced apart from one another along a direction along which the pin terminals are disposed.

### Claim 5 (depends on 1)

The board connector according to claim 1, wherein a cross-sectional area of the base is approximately equal to an area of the second through hole.

### Claim 6 (depends on 1)

The board connector according to claim 1, wherein the boss is further configured to define a gap between the end and the board when the connector is fully inserted.
