Abstract

A board connector (10) includes a receptacle (20) fittable to a mating connector and fixing members (60) for fixing the receptacle (20) to a circuit board (90). The receptacle (20) is in the form of a rectangular tube and has a pair of side walls (21) facing each other in a width direction and a bottom wall (22) and a ceiling wall (23) facing each other in a height direction. At least either the side walls (21) or the bottom wall (22) include(s) mounting recesses (31) for mounting the fixing members (60) within a wall thickness between an inner side surface and an outer side surface of the receptacle (20).

First claim

What is claimed is:

1. A board connector to be connected to a circuit board, the board connector comprising:
a forwardly-open receptacle fittable to a mating connector, the receptacle defining a substantially rectangular tube and having a bottom wall, two side walls projecting from opposite side edges of the bottom wall and facing each other in a width direction, a ceiling wall extending between the two side walls and facing the bottom wall in a height direction, each of the side walls including an erroneous connection prevention receiving groove open into the receptacle and spaced from the bottom wall;
mounting recesses formed within a wall thickness of each of the side walls at a position below the respective erroneous connection prevention receiving groove and at least partly aligned with the respective erroneous connection prevention receiving groove in the height direction, each of the mounting recesses having a rear-facing opening and a front wall opposite the rear-facing opening, and a bottom opening penetrating through the bottom wall, and a step extending in a front to rear direction forward of the bottom opening; and
fixing members inserted respectively into the respective mounting recesses for fixing the receptacle to the circuit board, each of the fixing members having a planar forward-facing inserting piece dimensioned to be inserted along the step and to lockably engage a portion of the respective mounting recess, and at least one fixing piece projecting from the forward-facing inserting piece in the height direction and in a common plane with the forward-facing inserting piece, the at least one fixing piece extending through the bottom opening to engage the circuit board.

2. The board connector of claim 1 , wherein the receptacle has a back wall and the mounting recess is open toward a side from which a terminal fitting to be mounted through the back wall is to be inserted.

3. The board connector of claim 1 , wherein a part of the side wall between the erroneous connection prevention receiving groove and the bottom wall having a larger height than a part of the side wall between the erroneous connection prevention receiving groove and the ceiling wall.

4. The board connector of claim 1 , wherein the fixing member is a metal plate.

5. The board connector of claim 1 , further comprising a second step spaced from and facing the step in a height direction.

6. The board connector of claim 5 , further comprising a locking projection on the insertion piece of the at least one forward-facing fixing member configured to lockably engage the second step.
