Abstract

A board connector has a plurality of contacts, an insulator holding the plurality of contacts, and a shell covering at least a part of the insulator. Each contact has an SMT terminal to be connected to a wiring pattern on a board. The insulator has a first insulator portion extending in an X-direction and two second insulator portions each extending in a Y-direction perpendicular to the X-direction. The first insulator portion has a bottom surface and first ends in the X-direction. Each second insulator portion has second ends. Each second insulator portion extends from the first ends to the second ends, respectively. The second ends are positioned on an imaginary straight line. The first insulator portion, the second insulator portions, and the imaginary straight line define a predetermined area. The SMT terminals are held by the insulator so that the SMT terminals are positioned within the predetermined area.

Claims

1. A board connector comprising:

a plurality of contacts each having an SMT (Surface Mount Technology) terminal to be connected to a wiring pattern on a board;

an insulator having a first insulator portion extending in a first direction and two second insulator portions each extending in a second direction perpendicular to the first direction, the first insulator portion having first ends in the first direction, the first insulator portion having a bottom surface, each of the second insulator portions having a second end, the second insulator portions extending from the first ends to the second ends, respectively, the second ends being positioned on an imaginary straight line, the first insulator portion, the second insulator portions and the imaginary straight line defining a predetermined area, the first insulator portion holding the plurality of contacts so that the SMT terminal is positioned in the predetermined area or on the bottom surface of the first insulator portion as seen from below the board connector; and

a shell covering, at least in part, the insulator.

2. The board connector according to claim 1, wherein:

the shell has a first shell portion and two second shell portions, the first shell portion and the second shell portions being formed integrally with each other;

the first shell portion covers, at least in part, the first insulator portion; and

the second shell portions cover the second insulator portions, respectively.

3. The board connector according to claim 2, wherein the second insulator portions and the second shell portions constitute receiver portions each of which receives a mating connector in part in a third direction perpendicular to the first and the second directions.

4. The board connector according to claim 2, a mating connector comprising a mating shell, wherein at least one of the second shell portions has a connection portion to be connected to the mating shell.

5. The board connector according to claim 2, wherein each of the second shell portions is formed with a hold-down portion which fixes the board connector to the board.

6. The board connector according to claim 1, wherein the first insulator portion holds the plurality of contacts so that the first insulator portion hides the contacts except the SMT terminals as seen from below the board connector.

7.
