Abstract: An electrical connector which has improved durability is provided. The housing of the connector has a first surface mounted on a mother board and a second surface on which a daughter board is mounted and which is disposed opposed to the first surface. On both ends of the first surface mounting legs are provided for receiving an edge of the mother board. On both ends of the second surface latch members for holding the daughter board and stoppers slightly spaced from the latch members are provided. When the daughter board is mounted on the connector, the latch members are prevented from being flexed excessively due to the contact of the latch members with the stop members. The daughter board and the connector are arranged in series and connected to each other such that the height of the assembly of the daughter board and the connector is lowered.

Abstract: A connector device comprising: a housing made of an insulating material, which has a groove including connection terminals for coming into electrical contact with a row array of connection terminals of a first circuit board inserted therein and with a second circuit board, the first circuit board being partially housed in the groove; latching means having a pair of metal strips mutually oppositely provided one at each end of the housing at an interval corresponding to a length of the first circuit board in a direction in which the connection terminals are arranged as the row array; the pair of metal strips elastically holding the partially inserted first circuit board therebetween under an elastic force acting in a direction perpendicular to that in which the connection terminals of the first circuit board are arranged as the row array; holding means for holding the latching means relative to the housing; and fixing means for positionally fixing the first circuit board, which is held by the latching means, re
