JP 2001-043914 A

In the above-described board connector, a plate-shaped terminal fitting is attached to the housing in a state in which the plate thickness direction is directed in the left-right direction parallel to the circuit board. Accordingly, the plate-like substrate connecting portion disposed behind the holding portion has its plate width direction (a direction perpendicular to the plate thickness direction) directed in the front-rear direction. Therefore, the board connector has a problem that a space necessary for arranging the board connection portion increases in the front-rear direction.
The present invention has been completed based on the above circumstances, and aims to reduce the size.

As a means for achieving the above object, the invention of claim 1 is configured by attaching a terminal fitting to a housing in which a hood portion protrudes from the outer peripheral edge of the holding portion in a direction substantially parallel to the circuit board. The terminal fitting has a substantially flat plate shape that is long in a direction substantially parallel to the protruding direction of the hood portion, and is penetrated by the holding portion with a plate thickness direction substantially parallel to the circuit board. A terminal connection part accommodated in the hood part, a substantially flat connection part connected to the base end part of the terminal connection part through a fold line substantially perpendicular to the circuit board, and flush with the connection part A substantially flat plate-like shape, and a board connecting part that extends from the connecting part in a direction substantially perpendicular to the circuit board and is connected to the circuit board, and the board connecting part is directly connected to the connecting part. A rectangular portion extending toward the circuit board side, and the square The extending direction leading edge of the section protrudes, where that is configured by a plurality of connecting pins which are inserted individually into the through hole of the circuit board is arranged so as to be lined up in the plate width direction of the rectangular portion Has characteristics.

  The invention according to claim 2 is characterized in that, in the invention according to claim 1, the plate width direction of the board connecting portion is inclined with respect to the length direction of the terminal connecting portion.

  A third aspect of the invention is characterized in that the board width direction of the board connecting portion is substantially perpendicular to the length direction of the terminal connecting portion.

<Invention of Claim 1>
The connecting portion that is flush with the board connecting portion is connected to the base end portion of the terminal connecting portion via a fold line that is substantially perpendicular to the circuit board. Therefore, the board width direction of the board connecting portion is the terminal connecting portion. This is a direction that intersects the length direction. Therefore, the space necessary for arranging the board connection portion in the length direction of the terminal connection portion is smaller than that in the case where the plate width direction of the board connection portion is the same direction as the length direction of the terminal connection portion.

<Invention of Claim 2>
Since the board width direction of the board connection part is an oblique direction with respect to the length direction of the terminal connection part, when a plurality of terminal fittings are arranged in parallel in the plate thickness direction of the terminal connection part, the parallel pitch is Even if it is small, the contact between adjacent substrate connection portions can be avoided.

<Invention of Claim 3>
Since the board width direction of the board connecting portion is oriented substantially perpendicular to the length direction of the terminal connecting portion, the arrangement space of the board connecting portion in the length direction of the terminal connecting portion can be reduced.
