Description

Technical Field

[0001] The utility model relates to a charging cable installation fixing sleeve. Background Art

[0002] A charging pile is an energy supplement device that provides power for electric vehicles. Its function is similar to a fuel dispenser in a gas station. It can be fixed on the ground or wall and installed in public buildings and parking lots of residential communities. It can charge various models of electric vehicles by adjusting voltage and current. The charging pile includes a charging gun and a charging cable. One end of the charging cable passes through the charging pile panel and is placed inside the charging pile to connect with electrical components, and the other end of the charging cable is connected to the charging gun. In the prior art, an opening with an approximate size corresponding to the diameter of the charging cable is provided on the charging pile panel for the charging cable to pass through, and a protective sleeve is arranged between the opening and the charging cable to improve the sealing performance between the charging cable and the opening, preventing external rainwater or impurities from invading the inside of the charging pile through the opening. However, in the prior art, the waterproof sealing performance of the sealing sleeve included in the protective sleeve is too low, resulting in the phenomenon of water seepage in the charging pile during long-term use. However, the current sealing sleeve is prone to displacement during the long-term plugging and unplugging process of the cable, resulting in a risk of insecure installation between the sealing sleeve and the protective sleeve, easy loosening and sliding of the sealing sleeve along the length direction of the cable, and relative rotation between the sealing sleeve and the protective sleeve during use, which is likely to cause rainwater to enter the cable position. During the installation process, there is a lack of positioning between the parts of the protective sleeve, and the installation effect is poor. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a charging cable installation fixing sleeve.

[0004] To achieve the above object, the utility model provides a charging cable installation fixing sleeve, which includes a protective sleeve and a sealing sleeve for sleeving an external charging cable. The protective sleeve is provided with a through hole for the sealing sleeve to pass through. The protective sleeve includes a first sleeve and a second sleeve. The first sleeve and the second sleeve can be fixedly installed by clamping the external charging pile panel. An abutting surface for the end of the sealing sleeve to abut and be limited is arranged on one axial end surface of the first sleeve. A first positioning mechanism for restricting the circumferential rotation of the sealing sleeve is arranged between the sealing sleeve and the abutting surface of the first sleeve. The first positioning mechanism includes a plurality of convex points arranged on the abutting surface and concave holes corresponding to the convex points on the sealing sleeve for insertion and positioning. The circumferential anti-rotation of the sealing sleeve and the protective sleeve can be formed through the insertion of the convex points and the concave holes.

[0005] Furthermore, a plurality of first mounting holes are uniformly distributed on the outer edge of the first sleeve, and a plurality of second mounting holes corresponding to the first mounting holes are arranged on the second sleeve. A grounding hole for grounding is arranged on the other axial end surface of the first sleeve.

[0006] Further, a positioning hole for installing one of the bumpers is provided on the abutting surface of the first kit. A spring is provided between the bumper and the bottom of the positioning hole. The bumper can be ejected outward or pressed inward along the axial direction of the first kit through the spring. When the bumper is aligned with the concave hole on the sealing sleeve, it can be driven to move into the concave hole and form a snap connection with the concave hole.

[0007] Further, a clamping assembly for clamping the sealing sleeve is provided at one end of the second kit. The clamping assembly includes a clamping ring, which is composed of a left clamping plate and a right clamping plate. The left clamping plate and the right clamping plate are arranged oppositely and both are in a semi-circular ring shape. The two ends of the left clamping plate are respectively arranged opposite to the two ends of the right clamping plate. Connecting plates are provided at the positions corresponding to the two ends of the left clamping plate on the front end face of the second kit. The connecting plates are located between the left clamping plate and the right clamping plate. Adjusting bolts are threadedly connected between the two ends of the left clamping plate and the corresponding ends of the right clamping plate respectively. The two adjusting bolts are respectively in threaded cooperation with the adjacent connecting plates.

[0008] Further, retaining edges are provided on both side walls of the connecting plate. The two retaining edges respectively extend towards the end of the left clamping plate and the end of the right clamping plate. Positioning grooves for guiding and positioning are provided at the ends of the left clamping plate and the right clamping plate corresponding to the retaining edges. The left clamping plate and the right clamping plate are pre-installed with the second kit through the sliding insertion of the retaining edges into the positioning grooves.

[0009] Further, the first kit and the second kit are coaxially arranged, and the outer peripheral wall of the first kit is aligned with the outer peripheral wall of the second kit.

[0010] The beneficial effects of the present utility model are as follows: First, the sealing sleeve is sleeved on the external charging cable, and then the protective sleeve is sleeved on the sealing sleeve. The protective sleeve can be installed and fixed on the external charging pile board through the separately arranged first kit and second kit. The first kit and the second kit are both coaxially provided with through holes. The waterproof sealing between the sealing sleeve and the fixed sleeve can be realized by directly sleeving the sealing sleeve on the cable, thereby improving the waterproof sealing performance at the opening of the charging pile board. The abutting surface provided on the first kit for inserting the end of the sealing sleeve can prevent the sealing sleeve from moving during the cable plugging and unplugging process, prevent the sealing sleeve from detaching, ensure the installation position of the sealing sleeve, and thus ensure the sealing effect. Moreover, the design of the first positioning mechanism ensures the precise connection between the sealing sleeve and the protective sleeve, reduces the error during the installation process, and ensures the use effect of the device. By preventing the rotation between the sealing sleeve and the first kit, the wear or generation of gaps between the sealing sleeve and the inner wall of the first kit can be prevented, so that the sealing sleeve is not easily displaced after installation, prevents the sealing sleeve from loosening and sliding along the length direction of the cable, can withstand long-term use and environmental changes, and has high durability.

[0015] The following further describes the embodiments of the present utility model with reference to the drawings: As shown in the figure, a charging cable installation and fixing sleeve includes a protective sleeve 1 and a sealing sleeve 2 for sleeving an external charging cable. The protective sleeve 1 is provided with a through hole for the sealing sleeve 2 to pass through. The protective sleeve 1 includes a first kit 3 and a second kit 4. The first kit 3 and the second kit 4 can be fixedly installed by clamping an external charging pile panel. An abutting surface 5 for the end of the sealing sleeve 2 to abut and be limited is arranged on an axial end surface of the first kit 3. A first positioning mechanism for restricting the circumferential rotation of the sealing sleeve 2 is arranged between the sealing sleeve 2 and the abutting surface 5 of the first kit 3. The first positioning mechanism includes a plurality of convex points 6 arranged on the abutting surface 5 and concave holes 7 corresponding to the convex points 6 on the sealing sleeve 2 for insertion and positioning. The circumferential anti-rotation of the sealing sleeve 2 and the protective sleeve 1 can be formed by the insertion of the convex points 6 and the concave holes 7.

[0016] A plurality of first mounting holes 8 are uniformly distributed on the outer edge of the first kit 3. The second kit 4 is provided with a plurality of second mounting holes 9 corresponding to the first mounting holes 8 one by one. A grounding hole 10 for grounding is arranged on the other axial end surface of the first kit 3. By screwing bolts through the first mounting holes 8 on the first kit 3 corresponding to the second mounting holes 9 on the second kit 4, the first kit 3 and the second kit 4 can clamp and fix the sheet metal therebetween, thereby realizing the fixed connection between the protective sleeve 1 and the external charging pile panel. At the same time, the tightness is improved through the cooperation of the first mounting holes 8 and the second mounting holes 9, and the disassembly and assembly efficiency is improved by adopting the above connection method, the cost expenditure is reduced, and the replacement of subsequent parts is facilitated; by installing a grounding wire corresponding to the grounding hole 10, the possible leakage of the protective sleeve 1 is grounded, which can effectively prevent the leakage of the protective sleeve 1 and improve safety.

[0017] The abutting surface 5 of the first kit 3 is provided with a positioning hole 11 for installing one of the bump points 6. A spring 12 is arranged between the bump point 6 and the bottom of the positioning hole 11. The bump point 6 can be ejected outward or pressed inward along the axial direction of the first kit 3 through the spring 12. When the bump point 6 is aligned with the concave hole 7 on the sealing sleeve 2, it can be driven to move into the concave hole 7 and form a clamping connection with the concave hole 7. The spring 12 between the bump point 6 and the positioning hole 11 is designed to allow the bump point 6 to be ejected outward or pressed inward along the axial direction of the first kit 3. This dynamic positioning mechanism helps the precise alignment and clamping between the sealing sleeve 2 and the protective sleeve 1. During the installation process, the sealing sleeve 2 can be rotated first, and at this time, the bump point 6 connected to the spring 12 is pressed. When the bump point 6 is aligned with the concave hole 7 on the sealing sleeve 2, the bump point 6 is driven to move into the concave hole 7, and there will be a sound after the bump point 6 impacts the corresponding concave hole 7, indicating that the installation is aligned and positioned at this time, improving the positioning effect. This automatic adjustment mechanism reduces the need for manual adjustment and improves the convenience of installation.

[0018] One end of the second kit 4 is provided with a clamping assembly for clamping the sealing sleeve 2. The clamping assembly includes a clamping ring, and the clamping ring is composed of a left clamping plate 13 and a right clamping plate 14. The left clamping plate 13 and the right clamping plate 14 are arranged oppositely, and both the left clamping plate 13 and the right clamping plate 14 are in a semi-circular ring shape. The two end parts of the left clamping plate 13 are respectively arranged oppositely to the two end parts of the right clamping plate 14. The front end face of the second kit 4 is provided with connecting plates 15 corresponding to the positions of the two end parts of the left clamping plate 13. The connecting plates 15 are located between the left clamping plate 13 and the right clamping plate 14. Adjusting bolts are threadedly connected between the two end parts of the left clamping plate 13 and the corresponding end parts of the right clamping plate 14 respectively. The two adjusting bolts are respectively in threaded cooperation with the adjacent connecting plates 15.

[0019] When it is necessary to clamp and limit the sealing sleeve 2, the operator moves the left clamping plate 13 and the right clamping plate 14 so that the left clamping plate 13 and the right clamping plate 14 approach each other relatively. At this time, the inner peripheral walls of the left clamping plate 13 and the right clamping plate 14 are both in partial abutting cooperation with the outer peripheral wall of the sealing sleeve 2, so as to realize the preliminary clamping and limiting of the sealing sleeve 2. Then the operator screws in the adjusting bolts, so that the two adjusting bolts respectively connect the two ends of the left clamping plate 13 and the two ends of the right clamping plate 14, and the adjusting bolts are in threaded cooperation with the connecting plates 15, so as to realize the abutting cooperation between the two ends of the left clamping plate 13 and the adjacent connecting plates 15 respectively, and at the same time, the two ends of the right clamping plate 14 are respectively in abutting cooperation with the adjacent connecting plates 15, so as to realize the connection combination of the left clamping plate 13 and the right clamping plate 14 with the fixed sleeve, so as to prevent the left clamping plate 13 and the right clamping plate 14 from shifting; through the above technical settings, the clamping and limiting of the sealing sleeve 2 are realized, and then the clamping and limiting of the charging cable are realized.

[0020] Both side walls of the connecting plate 15 are provided with edge stops 16. The two edge stops 16 respectively extend towards the ends of the left clamping plate 13 and the right clamping plate 14. Corresponding to the edge stops 16, the ends of the left clamping plate 13 and the right clamping plate 14 are both provided with positioning grooves 17 for guiding and positioning. The left clamping plate 13 and the right clamping plate 14 are pre-installed with the second kit 4 through the sliding insertion of the edge stops 16 and the positioning grooves 17. The cooperation between the edge stops 16 and the positioning grooves 17 can realize the guiding and positioning of the left clamping plate 13 and the right clamping plate 14, and can first fix the installation positions of the left clamping plate 13 and the right clamping plate 14 on the end face of the second kit 4, avoiding the inability to fix due to the shaking of the left clamping plate 13 and the right clamping plate 14 during the process of tightening the bolts. Through the pre-installation of the left clamping plate 13 and the right clamping plate 14, the risk of connection loosening or falling off is reduced, and the convenience of loading and unloading is improved.

[0021] Ensure that their pre-installation positions with the second kit 4 are accurate.

[0022] The first kit 3 and the second kit 4 are coaxially arranged, and the outer peripheral wall of the first kit 3 is aligned with the outer peripheral wall of the second kit 4.

[0023] The above embodiments are only one of the preferred specific embodiments of the present invention. All the usual changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention are included in the protection scope of the present invention.
