The front main elastic piece and the rear main elastic piece which are symmetrical to each other can keep accurate position size and elastic limiting space through the left positioning rib and the right positioning rib. The good and durable contact elasticity of the plugging area and the male terminal is ensured to be kept when the plugging area and the male terminal are matched and electrified, so that the transmission current is stable.
Further, as shown in fig. 1, the upper surface of the lower sheet 22 is provided with a riveting convex hull 221, the upper sheet 21 is provided with a positioning riveting hole 211 into which the riveting convex hull 221 extends, and the riveting convex hull 221 is caused to generate physical deformation by applying pressure to the riveting convex hull 221, so that the riveting convex hull 221 is caused to be riveted and fixed in the riveting hole 221.
It should be noted that, as shown in fig. 1, the rear end of the lower sheet 22 is bent upward to form a bending plate and then is connected with the U-shaped twisting plate 32 as a whole in fig. 4, and the rear end of the upper sheet 21 is bent upward along with the rear end of the lower sheet 22 to form a bending plate, so that the transition bending region and the press-riveting cable region form a slope (the transition bending region and the press-riveting cable region are not in the same horizontal line), and thus, the press-riveting cable region 30 and the transition bending region 20 form a height difference, thereby realizing smooth cable pressing.
A plurality of stress-relieving square grooves 212 are formed at the crease of the bending plate at the rear end of the upper sheet 21, so that the upper sheet 21 is bent more smoothly.
The inner side surface of the U-shaped pressing line coiled plate 31 is provided with an anti-slip groove 311, so that a larger pulling-out force value is provided after the pressing of the cable.
