Abstract
Description
Technical Field
[0001] This utility model relates to the field of charging gun cable fixing technology, and in particular to a charging gun cable fixing device. Background Technology
[0002] With the rapid development of new energy vehicles, the reliability and convenience of charging infrastructure have become key areas of technological research and development. As a core component for power transmission, the stability of the charging gun cable's fixing device directly affects the safety of the charging process and the user experience. Currently, the main solutions in the field of charging gun cable fixing technology are as follows: Traditional fixing devices typically use rigid clips or bolts to directly clamp the cable. This design has the following significant problems:
[0003] Insufficient versatility: Existing devices are mostly designed for specific cable diameters and lack adjustable structures. They cannot adapt to different cable specifications, forcing users to equip themselves with multiple models of devices, increasing costs and management complexity.
[0004] Poor stability: During charging, the cable often vibrates due to external pulling forces, and traditional single-point clamping structures are prone to loosening or even falling off, posing a safety hazard. In addition, the lack of multi-directional limiting at the fixing point of the cable exacerbates the risk of displacement.
[0005] Therefore, there is an urgent need for a charging gun cable fixing device that combines high versatility, stability, and ease of maintenance. This utility model effectively solves the shortcomings of existing technologies by using a conical fit design between the adapter sleeve and the locking sleeve, a double fixing structure, and an adjustable cable bracket, providing a better technical solution for new energy vehicle charging scenarios. Utility Model Content
[0006] In order to overcome the shortcomings of the prior art, this utility model discloses a charging gun cable fixing device.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A charging gun cable fixing device, comprising:
[0009] The adapter sleeve has an end plate at one end and an outer cone at the other end. The outer cone is provided with multiple necking grooves evenly spaced along its circumference. The sleeve body of the adapter sleeve is provided with external threads.
[0010] The locking sleeve has an inner thread on its inner wall that mates with the external thread of the adapter sleeve. One end of the locking sleeve has an inner cone that mates with the outer cone. By rotating the locking sleeve, the outer cone is driven to produce a radial necking action, which is used to clamp charging gun cables of different diameters.
[0011] A cable fixing bracket having at least two oblong holes for mounting the cable fixing bracket to the outer wall of the charging box above the cable hole by means of bolts engaging with the oblong holes;
[0012] The cable clamps are fixed to the cable fixing bracket at both ends by bolts to hold the charging gun cable.
[0013] Furthermore, the end plate is provided with multiple mounting holes along the circumference for mounting the adapter sleeve to the wiring hole on the side wall of the charging box by bolts.
[0014] Furthermore, the end plate of the adapter sleeve is threadedly engaged with the adapter sleeve by a clamping nut to be installed at the wire hole on the side wall of the charging box.
[0015] Furthermore, the cable fixing bracket includes a fixing surface, a first folded surface, a second folded surface, and a third folded surface. The fixing surface is provided with the oblong hole, and the second folded surface is a trapezoidal surface, with one side shorter than the other.
[0016] The pressure clamp is fixedly connected to the third fold surface by bolts.
[0017] Furthermore, the left side of the trapezoidal surface of the second fold is shorter than the right side.
[0018] Furthermore, the right side of the trapezoidal surface of the second fold is shorter than the left side.
[0019] Furthermore, the angle between the second fold and the third fold is 100° to 110°.
[0020] Furthermore, the third fold surface is provided with two threaded holes at intervals, and the pressure clamp is provided with mounting holes at both ends for fixing to the third fold surface by bolts.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] 1. By engaging the outer conical part of the adapter sleeve with the inner conical part of the locking sleeve, and combining the necking groove design, the outer conical part is driven to radially tighten when the locking sleeve is rotated, which can flexibly clamp charging gun cables of different diameters, significantly improving the applicability and compatibility of the device.
[0023] 2. The cable is secured by a dual structure of radial clamping with locking sleeve and bolt fixing with wire clamp, which ensures the cable is secure at the wire hole and further restricts cable displacement through clamp, effectively preventing loosening or detachment caused by external force during charging.
[0024] 3. The second fold of the cable fixing bracket adopts a trapezoidal design and forms an angle of 100°~110° with the third fold. This optimizes the bending path of the cable, reduces fatigue damage caused by excessive bending angle during long-term use, extends the service life of the cable, and can support the charging gun cable to be pulled and fixed in different directions to the left or right, meeting the diverse layout needs of new energy vehicle charging.

[0033] Example 1: When the charging gun is pulled to the left to charge a new energy vehicle. (Referring to the attached...) Figure 1 , 3 5. A charging gun cable fixing device, comprising:
[0034] The adapter sleeve 1 has an end plate 11 at one end and an outer cone 12 at the other end. The outer cone 12 is provided with a plurality of necking grooves 13 evenly spaced along its circumference. The sleeve body of the adapter sleeve 1 is provided with external threads.
[0035] In this embodiment, the end plate 11 is provided with a plurality of mounting holes 14 along the circumference. During installation, the adapter sleeve 1 is installed at the wire hole on the side wall of the charging box by bolts.
[0036] The locking sleeve 2 has an internal thread on its inner wall, which engages with the external thread of the adapter sleeve 1. One end of the locking sleeve 2 has an inner cone 21, which engages with the outer cone 12. That is, by rotating the locking sleeve 2, the locking sleeve 2 moves axially, causing the inner cone 21 to press the outer cone 12 inward, thus producing a radial necking action, which is used to clamp charging gun cables of different diameters.
[0037] Specifically, the locking sleeve 2 has a flat square body, which makes it easy to rotate the locking sleeve 2 with a wrench.
[0038] The cable fixing bracket 3 has at least two oblong holes 35 for mounting the cable fixing bracket 3 to the outer wall of the charging box above the cable hole by means of bolts engaging with the oblong holes 35.
[0039] As needed, the cable fixing bracket 3 includes a fixing surface 31, a first folded surface 32, a second folded surface 33 and a third folded surface 34. The fixing surface 31 is provided with an oblong hole 35. The cable fixing bracket 3 is installed on the outer wall of the charging box above the cable hole by bolts cooperating with the oblong hole 35. The second folded surface 33 is a trapezoidal surface, and the left side of the trapezoidal surface of the second folded surface 33 is shorter than the right side.
[0040] As needed, the angle between the second fold 33 and the third fold 34 is 100~110°. That is, the third fold 34 is formed by folding the outer edge of the second fold 33 at a 100~110° angle.
[0041] The wire clamp 4 is fixedly connected to the cable fixing bracket 3 by bolts at both ends to hold the charging gun cable;
[0042] Furthermore, the third fold surface 34 is provided with two threaded holes 36 at intervals, and the wire clamp 4 is provided with mounting holes 41 at both ends for fixing to the third fold surface 34 by bolts.
[0043] In use, firstly, the adapter sleeve 1 is installed at the cable hole on the side wall of the charging box by using the bolt and the mounting hole 14. Then, the charging gun cable is passed through the locking sleeve 2 and the adapter sleeve 1. Then, the locking sleeve 2 is rotated to generate axial movement, so that the inner cone 21 of the locking sleeve 2 presses the outer cone 12 inward. The outer cone 12 performs a necking action to hold the charging gun cable, thereby fixing the charging gun cable. Then, the cable fixing bracket 3 is installed on the outside of the side wall of the charging box and above the cable hole by using the bolt and the waist-shaped hole 35. Then, the wire clamp 4 is fixed to the third fold surface 34 of the wire clamp 4 by using the bolt, so that the wire clamp 4 and the third fold surface 34 cooperate to fix the charging gun cable at another position.
[0044] Example 2, in conjunction with Appendix Figure 4 A charging gun cable fixing device, which differs from Embodiment 1 in that: the end plate 11 of the adapter sleeve 1 does not have an assembly hole 14, but instead uses a clamping nut 5 to thread into the adapter sleeve 1, so that the adapter sleeve 1 is installed at the cable hole on the side wall of the charging box.
[0045] Example 3: When the charging gun is pulled to the right to charge a new energy vehicle. (Referring to the attached...) Figure 2 and 6 A charging gun cable fixing device, which differs from Embodiment 1 or 2 in that the right side of the trapezoidal surface of the second fold 33 is shorter than the left side.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the above embodiments should be regarded as exemplary and non-limiting in all respects.
