A connector includes a housing and a plurality of contacts, and the bottom portion of the housing has a holding bar for holding the contacts. In a region of the bottom portion of the housing corresponding to tips of all the contacts extending from the holding bar upwardly and toward the interior of the housing, a rectangular recess is provided, and a contact buckling-preventing plate is provided in the recess, which includes an upper surface portion formed with through-holes at locations corresponding to contact portions of the contacts, partition walls forming defined spaces for accommodating the contacts in cooperation with the upper surface portion, and jointing ends to be connected to both lateral inner ends of the recess on the side of the holding bar to permit a pivotal movement of the plate. In this manner, the connector can realize an even more reduced overall height and prevent the buckling of contacts upon extraordinary insertion and removal of a card-shaped connecting object.

Connector

An electrical connector includes a connector body to be mounted on a circuit board of an electrical appliance by means of protruding terminal legs of contacts incorporated in the connector body and by means of fixing legs of a shell as a worked body of a metallic plate forming an outer casing of the connector body. A mating connector socket of the shell is positioned so as to open outwardly of the electrical appliance. The shell has an auxiliary leg to be fixed to the circuit board. The auxiliary leg is formed by extension pieces extending from part of the shell on the side of the mating connector socket with respect to the fixing legs of the shell. The auxiliary leg serves to mount the electrical connector on the circuit board with great stability which is maintained for a long time.

Electrical connector

An electrical connector having a locking member which includes at one end an anchoring part shaped for hooking a mating connector, an engagement part to be secured to one of projections provided on both sides of a shell enclosing a main connector body, and at the other end a knob portion having a leaf spring. The engagement part is positioned between the anchoring part and the knob portion. The engagement part has a protrusion near to the center of the width of one end adjacent the knob portion, and two plate pieces on both the sides of the protrusion. Each of the plate pieces has a free end in the form of a resilient cantilever directing toward the protrusion. The spacing between the free ends of the two plate pieces is less than the width of the projection of the shell.
