Field of the Invention The present invention relates to an electrical connector having a contact having a locking projection fixed to a housing. 2. Description of the Related Art As a conventional electrical connector of this type, for example, the one shown in FIG.
064,391). This electrical connector 100
Is a housing 101, a plurality of contacts 103 locked and fixed to the housing 101, and these contacts 1
And a conductive shell 102 provided on the housing 101 so as to cover the housing 03. [0004] Each of the contacts 103 has a structure shown in FIG.
As shown in FIG.
A pair of locking projections 104 and 105 that are locked and fixed to 06 protrude from both sides. And the locking projection 10
The positions of 4 and 105 are separated from each other by a distance of H along the insertion direction of the contact 103,
Are asymmetrical with respect to the center line CL of FIG. The reason why the positions of the locking projections 104 and 105 are asymmetric is to make it possible to reduce the pitch between the adjacent contacts 103 and 103. On the other hand, contact 103
The contact receiving groove 106 of the housing 101 in which the contact 103 is locked has a contact insertion opening 107 which becomes wider toward the contact insertion end, thereby facilitating the insertion of the contact 103. As another conventional electrical connector, for example, the one shown in FIG. 5 is known. (3-95
The electrical connector 300 includes a housing 310 having a plurality of contact mounting holes 311 provided in parallel, a plurality of contacts 320 locked and fixed in the contact mounting holes 311 of the housing 310, and an inside of the housing 310. The flat cable 340 inserted into the contact 320
And a slider 330 that presses against the contact portion 325. [0005] Each of the contacts 320 is connected to a base 321 and a circuit board 3 extending from one side of the base 321.
A solder tine portion 326 soldered to the base portion 50;
1 from the other side, a flat cable 340 at the tip
And a contact mounting hole 3 extending upward from between the solder tine portion 326 and the spring portion 324 of the base portion 321.
11 and a contact mounting portion 322 locked and fixed to the contact mounting portion 11. Further, on the side edge of the contact mounting portion 322 on the solder tine portion 326 side, two locking projections 323 locked and fixed in the contact mounting hole 311 are provided, and the side edge of the contact mounting portion 322 on the spring portion 324 side is , And a straight side edge along the straight side wall of the contact mounting hole 311. However, in the conventional electric connector 100 shown in FIG. 4, when the contact 103 is inserted into the contact receiving groove 106 of the housing 101, the contact 103 is moved forward by a distance of H. Since one of the locking projections 105 contacts one side wall of the contact insertion opening 107 before the other locking projection 104 contacts the other wall, the contact 103 moves in the direction A shown in FIG. There is a problem that the contact 103 cannot be easily inserted due to rotation. A conventional electrical connector 300 shown in FIG.
In the contact 320, a locking projection 323 that is locked and fixed in the contact mounting hole 311 is provided on a side edge of the contact mounting portion 322 on the solder tine portion 326 side, and contacts the lower surface of the flat cable 340. It is not provided on the side edge of the spring portion 324 having the contact portion 325. The flat cable 340 is inserted into the contact portion 32 of the contact 320 by inserting the slider 330 into the housing 310.
5, the spring portion 324 bends downward, and a rotational moment is generated in the contact mounting portion 322 toward the spring portion 324, and the rotational moment causes the contact mounting of the locking protrusion 323. Hole 311
, And the posture of the contact mounting portion 322 with respect to the contact mounting hole 311 may be inclined. For this reason, the position of the contact point of the contact portion 325 at the tip of the spring portion 324 with the flat cable 340 is shifted downward, and there is a problem that it is difficult to maintain a predetermined contact force. Accordingly, an object of the present invention is to provide a contact having at least one pair of locking projections which are locked and fixed to the housing, the positions of which are asymmetric with respect to the center line, and the contact can be easily inserted. An object of the present invention is to provide an electrical connector that can be used. Another object of the present invention is to maintain the position of the contact point of the contact portion with the counterpart substrate by maintaining the position of the contact mounting portion with respect to the contact mounting hole in the contact, thereby ensuring a predetermined contact force. An object of the present invention is to provide an electrical connector that can be maintained at a high speed.
