The clamping member 72 includes: the two clamping pieces 721, the ends of the two clamping pieces 721 are symmetrically arranged arc-shaped clamping sections 722, a clamping opening 723 for clamping the insertion part 8 is formed between the two arc-shaped clamping sections 722, the other ends of the two clamping pieces 721 are mutually connected, elastic supporting rods 724 are arranged on two sides of one end of one clamping piece 721 far away from the clamping opening 723, the distance between the two elastic supporting rods 724 is larger than the width of the clamping piece 721, the elastic supporting rods 724 extend to one side far away from the clamping opening 723, a fixing rod 725 is vertically connected to one end of the elastic supporting rod 724 far away from the clamping opening 723, and the fixing rod 725 extends to a direction close to the other clamping piece 721; the connection part of the elastic supporting rod 724 and the fixed rod 725 is an arc-shaped limiting section 726;
The clamping pieces 721 and the inner wall of the insulating housing 71 form a movable gap, and two side walls in the insulating housing 71 are respectively provided with a limiting portion for limiting the positions of the two fixing rods 725, so that the two clamping pieces 721 can move in the insulating housing 71 under the supporting action of the elastic supporting rods 724.
Wherein the clamping piece 721 provided with the elastic supporting rod 724 is further provided with a protruding section opposite to the protruding direction of the arc-shaped clamping section 722, so that the clamping force between the two clamping pieces 721 can be increased.
Further, a gap is provided in the middle of the arc-shaped clamping section 722 to divide the arc-shaped clamping section 722 into two arc-shaped clamping units.
The connection of the connection part 7 and the insertion part 8 mainly uses the elastic clamping force of the two clamping pieces 721 to clamp the insertion part 8 so as to realize stable electric connection; the ends of the two clamping pieces 721 connected to each other are formed in a U shape, and the minimum distance between the two arc-shaped clamping sections 722 is 0 or smaller than the size of the insertion portion 8; in order to further ensure the contact stability of the insertion part 8 and the arc clamping sections 722, a gap is arranged in the middle of each arc clamping section 722, so that two arc clamping sections 722 are changed into four arc clamping units, the contact point position of the insertion part 8 and the arc clamping sections 722 can be improved, and the contact stability is ensured;
Considering that if the insertion position of the insertion portion 8 is shifted, or if the insertion position of the insertion portion 8 is shifted during subsequent use, there may be a larger contact force generated by the insertion portion 8 on one of the arc-shaped clamping sections 722 and a smaller contact force generated on the other arc-shaped clamping section 722, the contact between the insertion portion 8 and the arc-shaped clamping section 722 is not tight enough, so that the contact resistance is easily increased, the thermal resistance is increased, the power loss is caused, the power conversion efficiency is reduced, the charging efficiency is reduced, and the charging time is prolonged;
To solve this problem, it is ensured that both the two arc-shaped clamping sections 722 can be tightly contacted with the insertion portion 8, elastic supporting rods 724 capable of conducting electricity are respectively provided at both sides of one end of one of the clamping sections 721 far from the clamping opening 723, and the fixing rods 725 are used for realizing electric connection with the soldering pads of each PCB board, so that the fixing rods 725 are kept fixed due to connection with the PCB boards, the two clamping sections 721 are in a suspended state in the insulating housing 71, a certain degree of freedom is provided, the width of the provided elastic supporting rods 724 is smaller than the width of the clamping sections 721, so that when the force applied to the two clamping sections 721 by the insertion portion 8 is unbalanced, the elastic supporting rods 724 can be deformed at first, thereby the two arc-shaped clamping sections 722 are always kept tightly contacted with the insertion portion 8, thermal resistance generation is reduced, power loss at the connection position is prevented, and the conversion efficiency of the charger is further ensured.
Further, in order to secure contact stability, bumps may be formed on opposite sides of the two arc-shaped clamping sections 722, by which the tightness of contact of the arc-shaped clamping sections 722 with the insertion portion 8 is increased.

An insertion opening 714 is arranged on one side of the insulating shell 71 close to the clamping opening 723; the insertion port 714 can be inserted with the insertion portion 8.
The above-mentioned limiting part is mainly used for limiting the positions of the fixed rod 725 and the arc-shaped limiting section 726, and plays a stable supporting role on the elastic supporting rod 724 through the fixed rod 725 and the arc-shaped limiting section 726, and under the condition of not receiving external force, the elastic supporting rod 724 can effectively support the two clamping pieces 721;
Specifically, the two clamping pieces 721 and the inner side wall of the insulating housing 71 form a certain movable gap, the positions of the arc-shaped limiting sections 726 can be limited by the first limiting block 712 and the second limiting block 713 (as shown in fig. 8, the upper and lower directions of the arc-shaped limiting sections are limited), the positions of the fixing rods 725 can be limited by the clamping pieces 711 and the first limiting block 712 (as shown in fig. 8, the left and right directions of the fixing rods 725 are limited), the fixing rods 725 and the arc-shaped limiting sections 726 are fixed in the insulating housing 71, the elastic supporting rods 724 and the two clamping pieces 721 are stably supported, and when the forces applied to the two clamping pieces 721 by the insertion portion 8 are unbalanced, the elastic supporting rods 724 can be deformed at first, that is, deformed in the upper and lower directions shown in fig. 8, so that the two clamping pieces 721 are driven to slightly move in the upper and lower directions, and tight contact with the insertion portion 8 is ensured.
When the insulating housing 71 and the clamp 72 are attached, the side of the insulating housing 71 away from the insertion opening 714 is an open end, and the clamp 72 can be inserted and attached from the open end; specifically, one end of the clamp 72 (the end having the clamping port 723) is inserted from this open end, and since the width of the clamping piece 721 is smaller than the distance between the two elastic support rods 724, the stopper portion does not block the insertion of the clamping piece 721; when the elastic support rod 724 is inserted between the first limiting block 712 and the second limiting block 713, the insertion is continued (a smaller gap is formed between the side surface of the elastic support rod 724 and the inner wall of the insulating housing 71 without contact force or without affecting the deformation of the elastic support rod 724, until the fixing rod 725 contacts the clamping member 711, the side surface of the fixing rod 725 can form a squeezing action on the clamping plate 7112, the clamping plate 7112 retracts, when the fixing rod 725 passes over the clamping plate 7112, the clamping plate 7112 rebounds to form an abutting action on the side of the fixing rod 725 away from the clamping plate 721, and the arc-shaped limiting section 726 at this time is just limited by the first limiting block 712 and the second limiting block 713, thereby fixing the fixing rod 725 in the insulating housing 71.
