The present invention discloses a connector, which includes a male housing and a female housing. The male housing is formed of three side walls surrounding a circumference of a bottom wall and the female housing is formed of three side walls surrounding a circumference of a bottom wall. The male housing and the female housing are mateable with each other through mutual insertion. Practicing the connector of the present invention may reduce the wall thickness of the connector, making the connector thinner so as to enable use in a backlight module arrangement of relatively small space and provide module designing with more flexibility.
