BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 3, an electric connector 1 of the present invention comprises a plurality of terminals 2, an insulating body 3 and a cover 4.
including. The insulating main body 3 is a rectangular plate-like member, on which a plurality of terminal accommodating grooves 30 penetrating the plate body are provided, a cover is installed on the insulating main body, and They are configured so as to substantially match with each other and are slidable with respect to the insulating body. Further, the cover 4 is further provided with circular holes 40 equal in number to the terminal accommodating grooves 30 and distributed correspondingly thereto. When a pin (not shown) of the central processing unit penetrates the circular hole 40 and is inserted into the terminal accommodating groove 30 of the insulating body 3, this cover is slid toward the insulating body 3 by an external force. Since the pins of the central processing unit are inserted into the circular holes 40 of the cover 4, the pins of the central processing unit are interlocked with the sliding of the cover 4 and the terminals 2 of the electrical connector 1 are arranged along the sliding direction of the cover 4. Move in.

As shown in FIGS. 4 and 5, the terminal 2 includes a soldering portion 20, a fixing portion 21, and a connecting portion 2 which are integrally molded.
3, including the deforming portion 24 and the contact portion 22. The soldering part 2
0 is formed in a plate shape, is bent perpendicular to the fixing portion 21, and is soldered to a circuit board by a solder ball (not shown) provided in advance. Connection part 23
Extends from the fixed portion 21 to form a contact portion 22. Referring to FIGS. 6 and 7 together, the contact portion 22 is inclined in a direction perpendicular to the connection portion 23, and
3 and bend line 224. Further, the contact portion 22 includes a base 222 connecting the connecting portion 23 and a head portion 221,
The head portion 221 is extended from the base 222 in a circular arc shape in the forward direction. At the same time, an L-shaped curved portion is formed between the connecting portion 23 and the contact portion 22, and an inner edge portion of the L-shaped curved portion is punched out to form a deformed portion 24 having an appropriate width. The deformation portion 24 forms a boundary line 223 with the contact portion 22, and the thickness of the deformation portion 24 is thinner than that of the contact portion 22. The deformation portion 24 is thicker on the side close to the contact portion 22 and on the side distant from the contact portion 22. By making it thinner, a guide portion 241 similar to a blade is formed.

Is overlapped with the boundary line 223, the distance between the contact line a and the fixing portion 21 of the terminal 2 is H1, and H1 is increased by a certain distance with respect to H2. Therefore, in the initial pressing process, Since the moment arm is lengthened, the same moment effect can be realized with a small pressing force as compared with the prior art. When the pin 6 of the central processing unit is pushed to the L-shaped curved portion, the guiding unit 241 guides the pin 6 of the central processing unit so that the pin 6 is less likely to be caught in the L-shaped curved portion. The part 24 is superposed on the boundary line of the L-shaped curved part of the contact part 22, and the contact point is moved downward from the boundary line 223 to the curve 224. While the pin 6 is pushed in, until the contact line c overlaps the curve 224, that is, the contact line c is
