The free end 31 clamps a protruding block 21 of the fixing base 20 and is screwed to form a buckle through a fixing member (a bolt in this embodiment). Among them, the inner arc surface 301 of the two-arc buckle 30 is slightly oval, and the inner arc surface 301 is provided with a plurality of bumps 36 inward (toward the cable 70) for holding the cross section of the cable 70 Forming an oval shape makes it difficult for the cable 70 to generate a turning moment and prevents twisting.

The back cover 40 is disposed on one side of the arc-shaped buckle 30 away from the fixing base 20 and is locked to the casing 10, and defines a space inside the charging gun where the cable 70 is disposed. In this embodiment, the back cover 40 has a main chamber covering a main part of the two-arc-shaped buckle 30, and a plurality of first engaging structures 45 are protruded on the inner wall of the chamber to be able to interact with the outer curved surface of the arc-shaped buckle 30 The first engaging structure 37 recessed in 302 engages with each other to generate a group of positioning structures. As shown in FIG. 2 and FIG. 3, four groups of positioning structures are protruded from the center of the back cover 40 on the inner wall of the container at an equal angle with the center of the back cover 40 as a center. The screw positioning holes make it difficult for the back cover 40 and the arc buckle 30 to generate a rotating moment.

With this, the arc-shaped buckle 30 can be fixed to the fixing base 20 and clamp the cable 70, and at the same time form a structural engagement with the back cover 40, so that the cable 70 is not pulled or twisted inside the charging gun, and the components at the connection can be reduced. The structure is aging and deformed to prevent water leakage and electricity leakage.

In this embodiment, a second engaging structure 38 is protruded on the top surface 303 of the two-arc retaining ring 30, and a second engaging structure 25 is correspondingly recessed on the fixing base 20 so as to be able to engage with the second engaging of the arc-shaped retaining ring 30 The 38 structures are engaged with each other to generate a group of positioning structures, so that the arc-shaped buckle 30 and the fixing base 20 form a torsion-resistant structure. In addition, in this aspect, the first engaging structure 37 and the second engaging structure 25 of the arc-shaped retaining ring 30 are respectively located on two mutually perpendicular sides 302 and 303 of the arc-shaped retaining ring 30 to match the cards of adjacent components. With the combined structure, the structure of the arc buckle 30 can be simplified. However, a technician can also design the first engaging structure 37 and the second engaging structure 25 on opposite sides of the arc-shaped buckle 30 or change the appearance of the engaging structure to form a tenon according to requirements.
