The 丨〇 interferes with the side wall of the terminal receiving groove 24 to hold the terminal 1 in the terminal receiving groove 24, and the tail portion 12 of the conductive terminal 1 is soldered to the circuit board 4 through a solder ball 5, and the deflecting portion 1342 of the conductive terminal 1 extends. The upper surface of the insulating body is provided with a rib 2 between adjacent two longitudinal rows of conductive terminals 1. The end portion 1 3 4 6 of the conductive terminal 1 extends downward to the upper surface of the rib 26. It can be seen that the terminal 1 344 of the conductive terminal i in the rear terminal slot 24 extends after the terminal 1 is received in the terminal receiving groove 24 to the side of the adjacent front terminal slot 24 (on the upper and lower sides of the drawing) The direction is the front-rear direction), the guiding portion 1 344 and the adjacent front conductive terminal! The extension 134〇 is staggered. As can be seen from the sixth and seventh figures, the guiding portions 1 3 44 of the terminals 1 in the same longitudinal row (only one conductive terminal is drawn in each longitudinal row in the sixth drawing) are opposite to the corresponding extending portions 134.偏移 Offset to the same side by a certain distance. When the terminal 1 is pressed, the guiding portion 1 34 4 will simultaneously shift forward and downward, since the guiding portions 1 34 4 are both biased to one side with respect to the extending portion 1 3 4 0 . Therefore, when the guiding portion 1344 is forked, the guiding portion 1344 of the conductive terminal 1 in the one terminal slot 24 can be exactly shifted from the extending portion 134 of the conductive terminal 1 in the previous terminal slot 24. 5. Description of the invention (5) That is, when the one-substance is pressed, the guiding portion 1 344 of the adjacent conductive terminal 1 does not overlap with the extending portion 1340 in the vertical direction (the pressing direction when the terminal 1 is pressed is the vertical direction), thereby effectively avoiding the adjacent The extension 134 of the terminal 1 is phased to cause a short circuit. On the other hand, since the end portion 1346 of the conductive terminal extends below the upper surface of the ridge 26, the electrical connector is transported and used, and the portion 1 346 is hooked on other objects to cause damage to the terminal. In view of the above, the present invention has indeed met the requirements of the invention and has been applied in accordance with the law.
