Electrical connector

An electrical connector for connecting a first circuit board to a second circuit board, comprising:

• a first housing mountable on the first circuit board, the first housing having a first latching member extending longitudinally from each end of the first housing, each of the first latching members having a guide groove which is parallel with a mating direction of the first housing and including a transverse ride positioned in the guide groove and at least partially intersecting the guide groove normal to the mating direction of the first housing;
• a plurality of first contacts positioned in the first housing for establishing an electrical interconnection to the first circuit board;
• a second housing mountable on the second circuit board, the second housing having a second latching member extending longitudinally from each end of the second housing, each of the second latching members having a projection which is parallel with a mating direction of the second housing and including a transverse recess which is at least partially intersecting the projection normal to the mating direction of the second housing;
• and
• a plurality of second contacts positioned in the second housing for establishing an electrical interconnection to the second circuit board;
• whereby as the projection of the second housing is fittedly inserted into the guide groove of the first housing, the first and second housings are matingly connected and latched to each other through a frictional engagement of the transverse ridge and the transverse recess and the first and second contacts are matingly connected together.
