As shown in fig. 1 to 5, the base 1 is provided with a mounting groove 11 recessed downward, side walls 12 positioned on opposite sides of the mounting groove 11, blocking walls 13 positioned on opposite sides of the mounting groove 11, and a bottom wall 14 positioned below the mounting groove 11.

The inclined surface having only one inclination angle with respect to the end of the bottom wall 14 is used for supporting the body 4, and the requirement of the fastening portion 1311 to fasten the body 4 with different sizes cannot be met. For example, when the fastening portion 1311 is designed to have a proper size and a proper fastening position according to the requirement that the fastening portion 1311 just can fasten the body 4, and when the body 4 with a small size is mounted to the mounting groove 11 due to manufacturing tolerance or customer requirement, the body 4 with a small size moves down due to the inclined surface with only one inclined angle, and the fastening portion 1311 cannot abut against and fasten the body 4; for example, in order to satisfy the requirement that the engagement portion 1311 can abut against and hold the body 4 of a small size, when the body 4 of a large size is mounted in the mounting groove 11, since the inclined surface having only one inclination angle is provided, the body 4 of a large size is moved upward, so that the engagement portion 1311 has a large interference of abutting against and holding the body 4, thereby affecting the mounting of the body 4 of a large size in the mounting groove 11.

The second spring plate 214 abuts against the slot wall 1214 in a direction approaching the mounting slot 11, and is in interference fit with the slot wall 1214, and the first arm 211 is kept in a gap.

(2) On the basis of not increasing the height of the terminal 2, the first through groove 25 is arranged to penetrate through the first elastic piece 213, so that the length of the first through groove 25 is enough to avoid affecting the downward displacement stroke of the lead 5, and the length of the first elastic piece 213 which is far away from the mounting groove 11 and is bent downwards is enough to ensure that the first elastic piece 213 is favorable for having enough supporting force to support the first blocking part 1212 downwards, so that the situation that kneeling PIN is easily caused by excessive bending of the first elastic piece 213 in the process of preventing the first elastic piece 213 and the first blocking part 1212 from being separated from each other is avoided.

(3) On the basis of not increasing the height of the terminal 2, the second through slot 26 is arranged to penetrate through the third elastic piece 242, so that the length of the second through slot 26 is enough to avoid affecting the downward displacement travel of the wire 5, and the length of the third elastic piece 242 far away from the mounting slot 11 and extending downwards in a bending manner is also enough to be favorable for driving the spring arm 24 to displace downwards when the wire 5 displaces downwards and is clamped by the clamping part 263, and the third elastic piece 242 abuts against the second blocking part 1213 to prevent the spring arm 24 from being difficult to kneel PIN when being over-pressed.
