[0032] Refer to the attached Figure 3 - attached Figure 6 , a new type of wire fixing structure, used in cooperation with a housing P with a wire passing port P1, which includes a sleeve member 1 and a limiting member 2. The head end of the sleeve member 1 abuts against the outer wall of the housing P, and the tail end of the sleeve member 1 penetrates through the wire passing port P1; a sleeve hole 10 communicating with the outside and the inside of the housing P is also provided on the sleeve member 1, and the cable S penetrates through the sleeve hole 10 and is in interference fit with the sleeve hole 10; the limiting member 2 is arranged inside the housing P and connects to the tail end of the sleeve member 1 to fix the sleeve member 1 on the housing P.

[0033] Specifically, during installation, first pass the cable S through the sleeve hole 10 and reserve a certain length, then insert the tail end of the sleeve member 1 into the wire passing port P1 and make the head end of the sleeve member 1 abut against the outer wall of the housing P, and finally place the limiting member 2 into the housing P and connect to the tail end of the sleeve member 1, then the sleeve member 1 and the cable S can be fixed on the housing P.

[0034] In summary, this wire fixing mechanism is used in cooperation with the limiting member 2 by setting the sleeve member 1, which facilitates the installation of the cable S onto the housing P. The interference fit between the sleeve hole 10 and the cable S can increase the contact area and damping degree between the sleeve member 1 and the cable S to prevent the cable S from shaking, thereby effectively improving the installation stability of the cable S and reducing the wear of the cable S.

[0035] Refer to the attached Figure 5 - attached Figure 9 , the sleeve member 1 includes an upper pressing sleeve 11 and a lower pressing sleeve 12, and the upper pressing sleeve 11 and the lower pressing sleeve 12 are assembled with each other and enclose to form the sleeve hole 10.

[0036] Specifically, during installation, first open the upper pressing sleeve 11 and the lower pressing sleeve 12, place the cable S on the lower pressing sleeve 12, and then fix the upper pressing sleeve 11 and the lower pressing sleeve 12 to make the cable S in interference fit with the enclosed sleeve hole 10; the assembled design of the upper pressing sleeve 11 and the lower pressing sleeve 12 facilitates the disassembly and assembly of the cable S.

[0037] Refer to the attached Figure 9, the upper pressing sleeve 11 is provided with a screw hole 111 and a socket 112, the lower pressing sleeve 12 is provided with a bolt 121 and a plug post 122, the plug post 122 is inserted into the socket 112, one end of the bolt 121 abuts against the lower pressing sleeve 12, the other end of the bolt 121 penetrates through the lower pressing sleeve 12 and is threadedly connected to the screw hole 111 to fix the upper pressing sleeve 11 and the lower pressing sleeve 12.

[0038] Specifically, the cooperation of the plug post 122 and the socket 112 can accurately align the upper pressing sleeve 11 with the lower pressing sleeve 12 to enclose and form a sleeve hole 10, and the cooperation of the bolt 121 and the screw hole 111 can fix or loosen the upper pressing sleeve 11 from the lower pressing sleeve 12.

[0039] It should be noted that, in addition to using the bolt 121 to connect the upper pressing sleeve 11 and the lower pressing block, the upper pressing sleeve 11 and the lower pressing block can also be directly fixed by a buckling method. Due to the diverse connection methods, this is not limited in the present utility model.

[0040] Refer to the appendix Figure 5 and the appendix Figure 9 , the upper pressing sleeve 11 and the lower pressing sleeve 12 are respectively provided with a first pressing block 11k and a second pressing block 12k in the sleeve hole 10, the first pressing block 11k and the second pressing block 12k cooperate with each other to synchronously press against the cable S tightly, and there are multiple first pressing blocks 11k and second pressing blocks 12k which are linearly arrayed along the axis line of the sleeve hole 10.

[0041] Specifically, the cooperation of multiple first pressing blocks 11k and multiple second pressing blocks 12k can synchronously limit multiple parts of the cable S to further improve the damping between the upper pressing sleeve 11, the lower pressing sleeve 12 and the cable S, and ensure that the cable S can be more stably fixed in the sleeve hole 10.

[0042] Refer to the appendix Figure 6 - the appendix Figure 7 , the housing P is also provided with a notch P2 communicating with the wiring opening P1, the upper pressing sleeve 11 and the lower pressing sleeve 12 are provided with a buckling position 13 at the tail end of the sleeve member 1; the limiting member 2 abuts against the inner side wall and the inner bottom wall of the housing P, and the limiting member 2 is provided with a buckle 21, and the buckle 21 can enter the sleeve hole 10 through the notch P2 and be buckled to the buckling position 13 to limit the movement and rotation of the sleeve member 1.

[0043] Specifically, during installation, first insert the tail end of the sleeve member 1 into the wiring opening P1 and make the head end of the sleeve member 1 abut against the outer wall of the housing P, then extend the buckle 21 of the limiting member 2 into the sleeve hole 10 to be buckled to the buckling position 13, and make the limiting member 2 abut against the inner side wall and the inner bottom wall of the housing P, then the movement and rotation of the sleeve member 1 can be limited; and in this structure, there is no need to use screws to fix the sleeve member 1 or the limiting member 2, which not only improves the disassembly and assembly convenience but also reduces the mold opening cost.

[0044] Refer to the appendix Figure 5 and the appendixFigure 8 , at the end of the sleeve member 1, the upper pressing sleeve 11 and the lower pressing sleeve 12 are provided with a groove 14. One side of the groove 14 is open for the buckle 21 to enter, and the other side of the groove 14 approaches the buckle position 13 and is provided with an inclined surface 140 for abutting against the end of the buckle 21; when the buckle 21 moves along the groove 14 towards the buckle position 13, the end of the buckle 21 is guided by the inclined surface 140 to disengage from the groove 14 and enter the buckle position 13; therefore, the design of the groove 14 can assist the end of the buckle 21 to be buckled to the buckle position 13, improving the installation convenience of the limiting member 2 and the sleeve member 1.

[0045] Refer to the appendix Figure 8 - appendix Figure 9 , considering that relying solely on the buckle 21 to limit the rotation of the sleeve member 1 is likely to cause the buckle 21 to break. To solve this problem, in the present utility model, the upper pressing sleeve 11 and the lower pressing sleeve 12 are provided with a cooperating formed block 15 at the end of the sleeve member 1, and the limiting member 2 is provided with a bayonet 22 cooperating with the block 15; when the buckle 21 is snapped into the buckle position 13, the block 15 is inserted into the bayonet 22 to limit the rotation of the sleeve member 1, thereby reducing the possibility of the buckle 21 breaking.

[0046] Refer to the appendix Figure 6 - appendix Figure 8 , a retaining strip P3 is provided on the inner side wall of the housing P, and a retaining notch 23 cooperating with the retaining strip P3 is provided on the limiting member 2.

[0047] Specifically, when the limiting member 2 abuts against the inner side wall and the inner bottom wall of the housing P, the retaining strip P3 needs to be placed in the retaining notch 23 to prevent the incorrect installation of the limiting member 2. Therefore, the cooperation of the retaining strip P3 and the retaining notch 23 has an anti-fooling function.

[0048] On the other hand, considering that during the installation of the limiting member 2, there may be a gap between the limiting member 2 and the inner bottom wall of the housing P, resulting in the easy swinging of the limiting member 2 and the inability to stably limit the rotation of the sleeve member 1; while the retaining strip P3 can abut against the side of the limiting member 2 to eliminate the gap, ensuring that the limiting member 2 can stably limit the rotation of the sleeve member 1.

[0049] Refer to the appendix Figure 10 , a charging pile includes a housing 3, a control unit 4, a power supply socket 5 and this new type of wire fixing structure. The control unit 4 is installed inside the housing 3, the power supply socket 5 is arranged on the housing 3 and is electrically connected to the control unit 4. The energized power supply socket 5 is used to charge the charging gun. The housing 3 replaces the housing P, the wire passing port 30 of the housing 3 replaces the wire routing port P1 of the housing P, the sleeve member 1 is installed at the wire routing port P1 of the housing 3, the limiting member 2 is installed inside the housing 3 and is used to limit the movement and rotation of the sleeve member 1, and the cable S passes through the sleeve hole 10 of the sleeve member 1 and is electrically connected to the control unit 4.

[0050] Specifically, since the charging pile installs the wire fixing mechanism by replacing the housing 3 with the casing P, it also has the advantages brought by the wire fixing mechanism, ensuring that the cable S can be stably electrically connected to the internal control unit 4 after installation; regarding the installation methods of the cable S, the sleeve member 1, the limiting member 2, and the housing 3, reference can be made to the above content and will not be repeated here; and regarding the designs of the control unit 4 and the power supply socket 5, they also belong to the prior art and will not be elaborated in detail here.

[0051] It should also be noted that although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present application.
