DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 As shown, the wire pressing structure of the embodiment of the utility model includes: a wire clamp body 10, a fastener 20, a wire pressing turntable 30 and a C-shaped retaining spring 40, wherein the wire clamp body 10 is annular, and a thread groove 11 is provided on the top of the wire clamp body 10; the fastener 20 includes a screw rod 21 and a light rod 22, the screw rod 21 is threadedly connected to the thread groove 11 of the wire clamp body 10, and a first groove 23 is provided on the light rod 22; the wire pressing turntable 30 is provided with a through hole 31, and the wire pressing turntable 30 is sleeved on the light rod 22 through the through hole 31, wherein the diameter of the through hole 31 is smaller than the diameter of the screw rod 21; the C-shaped retaining spring 40 cooperates with the first groove 23 of the fastener 20 to limit the wire pressing turntable 30 on the light rod 22.

[0026] It should be noted that since the wire crimping structure of the embodiment of the utility model limits the wire crimping turntable 30 on the bare rod 22, when installing the cable, the screw 21 of the fastener 20 can be controlled to move downward through the threaded groove 11 to rotate the wire crimping turntable 30 and fix the cable between the wire crimping turntable 30 and the wire clamp body, so that it is suitable for the installation and fixation of cables with different diameters and cross-sections, and solves the problem of cumbersome installation caused by different cable diameters in different regions at home and abroad; in the process of tightening the cable, the torsional force applied to the fastener 20 corresponds to the cable pulling force required by the user, and the tightening torque can be accurately defined; by utilizing various mechanisms such as geometric shapes, torsional contact, internal guides, etc., it is ensured that the wire crimping structure automatically adjusts and is located at the center or close to the center of the target position during the contact or assembly process with the cable, and has high applicability.

[0027] like Figure 1 As shown, in one embodiment of the present invention, a screw head 24 is provided at the top of the screw rod 21 , and a torsional force can be applied to the fastener 20 by rotating the screw head 24 .

[0028] Specifically, Figure 2 As shown, the top surface of the screw head 24 may be provided with a cross-shaped groove to facilitate the rotation of the screw head 24. It is understandable that the specific structure of the screw head 24 is not limited here. In other specific embodiments, grooves of other shapes may be provided on the top surface of the screw head 24 according to user needs, such as a straight groove provided on the top surface of the screw head 24. The screw head 24 may be a round screw head or a polygonal screw head, which is not limited in this embodiment.

[0029] like Figure 3 As shown, in one embodiment of the present utility model, a protrusion 32 is provided at the bottom of the wire pressing rotary disk 30. By adding the protrusion 32, the pressure between the wire pressing rotary disk 30 and the cable can be increased to prevent the cable from loosening and moving.

[0030] Specifically, Figure 3 As shown, there may be a plurality of protrusions 32, and the plurality of protrusions 32 are circumferentially distributed on the circumference outside the through hole 31, so that when the wire pressing rotary disk 30 rotates, the cable is subjected to uniform force.

[0031] like Figure 4 As shown, in one embodiment of the present invention, a second groove 12 is provided at the bottom of the wire clamp body 10, and the wire pressing structure further includes: a small wire diameter component 50, the small wire diameter component 50 includes an arc-shaped base 51 and a support leg 52, and the support leg 52 cooperates with the second groove 12. The small wire diameter component 50 can be selectively installed or removed according to the diameter of the installed cable. When the cable diameter is small (for example, 10mm to 24mm), the small wire diameter component 50 can be installed in the wire pressing structure, and the cable is installed and fixed between the wire pressing turntable 30 and the arc-shaped base 51 of the small wire diameter component 50, so as to realize the installation and fixation of the small wire diameter cable.

[0032] like Figure 4 As shown, in one embodiment of the present invention, there are multiple second grooves 12 and multiple legs 52, and the multiple legs 52 correspond to the multiple second grooves 12 one by one, so that the small wire diameter component 50 can be firmly fixed on the wire clamp body 10.

[0033] like Figure 4 As shown, in one embodiment of the utility model, the center of the cross section of the arc base 51 is in a straight line with the axis of the through hole 31 of the crimping turntable 30 and the axis of the thread groove 11. It should be noted that by arranging the center of the cross section of the arc base 51 and the axis of the through hole 31 of the crimping turntable 30 and the axis of the thread groove 11 in a straight line, the space between the crimping turntable 30 and the arc base 51 can be effectively utilized to achieve automatic adjustment of the cable position during contact with the cable or assembly process and to make it in the center or close to the center of the target position.

[0034] like Figure 4As shown, in one embodiment of the utility model, the wire pressing structure may further include a mounting ear 60, and a mounting hole is provided on the mounting ear 60, and the wire pressing structure can be fixed in the charging pile through the mounting hole and a combination screw. Specifically, there can be two mounting ears 60, which are respectively fixedly provided on the outer side walls on both sides of the wire pressing structure, and the wire pressing structure can be stably fixed in the charging pile through the mounting holes and the combination screws on both sides of the wire pressing structure. It can be understood that the specific structure and number of the mounting ears 60 are not limited here. In other specific embodiments, it is also possible to fix the wire pressing structure in the charging pile by clamping instead of providing a mounting hole on the mounting ear according to the needs of the user, or to provide a plurality of mounting ears on the wire pressing structure to achieve the fixation of the wire pressing structure.

[0035] Figure 5 The figure shows the state of the wire pressing structure of a specific embodiment of the utility model when installing different cables. Figure 5 As shown, the small wire diameter component 50 is used when installing and fixing the small wire diameter cable on the left side to prevent the small wire diameter cable from moving in a larger space, causing the small wire diameter cable to fall out of the wire pressing structure; the small wire diameter component 50 is removed when installing and fixing the large wire diameter cable on the right side to meet the diameter requirements of the large wire diameter cable. It can be seen that the arrangement of the second groove 12 and the small wire diameter component 50 can effectively improve the applicability of the wire pressing structure.

[0036] According to the wire pressing structure of the embodiment of the utility model, the wire pressing turntable is limited on the bare rod by cooperating with the first groove of the fastener through the C-shaped retaining spring. When installing the cable, the screw of the fastener can be controlled to pass through the threaded groove and move downward to rotate the wire pressing turntable and fix the cable between the wire pressing turntable and the wire clamp body. It can be suitable for the installation and fixation of cables with different diameters and cross-sections, and solves the problem of cumbersome installation caused by different cable diameters in different regions at home and abroad. In the process of tightening the cable, the torsional force applied to the fastener corresponds to the cable pulling force required by the user, and the tightening torque can be accurately defined. By utilizing various mechanisms such as geometric shapes, torsional contact, internal guides, etc., it is ensured that the wire pressing structure automatically adjusts and is located at the center or close to the center of the target position during the contact or assembly process between the wire pressing structure and the cable, and has high applicability.
