Description
Technical Field
[0001] This utility model relates to the field of liquid-cooled charging gun technology, and more specifically, to a liquid-cooled charging gun wire fixing structure. Background Technology
[0002] Liquid-cooled charging guns are a technology used in charging new energy vehicles. They reduce heat accumulation during the charging process through a liquid circulation system, achieving efficient heat dissipation. The core technology involves setting up a dedicated liquid-cooled circulation channel between the cable and the charging gun, utilizing coolant and a power pump to circulate and dissipate heat, preventing the cable from overheating.
[0003] During use, existing liquid-cooled charging guns are prone to cable pulling, which can cause the connection between the cable and the end of the charging gun to loosen and detach over time. This not only affects the normal use of the liquid-cooled charging gun but also poses a risk of electric shock. Therefore, we propose a cable fixing structure for liquid-cooled charging guns to solve the above problems. Utility Model Content

[0010] A clamping plate for cable fixing is symmetrically installed between the double-headed positive and negative lead screw and the guide rod. The edge of the clamping plate is integrally formed with connecting ears symmetrically. One of the connecting ears is slidably connected to the guide rod, and the other connecting ear is screwed to the double-headed positive and negative lead screw.
[0011] The port portion of the casing is fitted with a cover plate by screws.
[0012] Furthermore, the clamping surface of the clamping plate is integrally formed with anti-slip protrusions, and the anti-slip protrusions are in close contact with the cable.
[0013] Furthermore, the surface of the housing corresponding to the connecting seat is symmetrically provided with countersunk holes, and the connecting seat is provided with screw holes at the part corresponding to the countersunk holes.
[0014] Furthermore, the middle part of the casing is provided with a first through hole for threading a cable, and the inner diameter of the first through hole is larger than the outer diameter of the cable.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0030] Example:
[0031] Please see Figure 1-5 A liquid-cooled charging gun cable fixing structure includes a liquid-cooled charging gun body 1, a connector 2 fixedly connected to the end of the liquid-cooled charging gun body 1, and a cable 3 installed on the connector 2. A sleeve 4 fixedly connected to the connector 2 is sleeved on the cable 3. A guide rod 5 is fixedly connected to the inner side of the sleeve 4. A double-headed positive and negative screw 6 is rotatably connected to one side of the guide rod 5. A cross groove 7 is opened at one end of the double-headed positive and negative screw 6.
[0032] The side wall of the housing 4 is provided with an adjustment groove 8 extending to the cross groove 7. The inner side of the adjustment groove 8 is detachably connected to a positioning seat 11 by screws. The positioning seat 11 is integrally formed with a cross protrusion 12 that forms an embedded structure with the cross groove 7.
[0033] A clamping plate 9 for securing the cable 3 is symmetrically installed between the double-ended positive and negative screw 6 and the guide rod 5. The edge of the clamping plate 9 is integrally formed with connecting ears 10 symmetrically. One connecting ear 10 is slidably connected to the guide rod 5, and the other connecting ear 10 is screwed to the double-ended positive and negative screw 6.
[0034] A cover plate 13 is installed at the port of the casing 4 by screws;
[0035] It should be noted that when using this liquid-cooled charging gun cable fixing structure, firstly, the housing 4 and the cover plate 13 are sequentially placed on the cable 3. Then, the housing 4 is fixedly connected to the connecting seat 2. By using a tool with the cross groove 7 to screw the double-headed positive and negative screw 6, the connecting ear 10 slides with the guide rod 5, thereby causing the two symmetrically arranged clamping plates 9 to move towards each other until the clamping plates 9 are tightly attached to the cable 3, thus achieving the function of fixing the cable 3. This prevents the part of the cable 3 connected to the connecting seat 2 from being pulled during the use of the liquid-cooled charging gun body 1, preventing loosening and falling off, ensuring the normal use of the liquid-cooled charging gun, and avoiding the risk of electric shock. Finally, the cover plate 13 is fixed to the port of the housing 4.
[0036] By assembling a positioning seat 11 on the inner side of the adjustment groove 8, and embedding the cross protrusion 12 on the positioning seat 11 into the cross groove 7, and then fixing the positioning seat 11 to the inner side of the adjustment groove 8 with screws, the double-headed positive and negative lead screw 6 can be effectively prevented from loosening, thereby ensuring the stability of the clamping plate 9 in clamping the cable 3.
[0037] like Figure 3 As shown, the clamping surface of the clamping plate 9 is integrally formed with anti-slip protrusions, and the anti-slip protrusions are closely attached to the cable 3. The clamping plate 9 is set in a semi-circular structure.
[0038] It should be noted that the 9-layer semi-circular structure of the clamping plate can effectively increase the contact area between the clamping plate 9 and the cable 3. At the same time, the anti-slip protrusions can increase the friction between the cable 3 and the clamping plate 9, ensuring the stability of the clamping plate 9 in securing the cable 3.
[0039] like Figure 3 As shown, countersunk holes are symmetrically provided on the surface of the corresponding connecting seat 2 of the housing 4, and screw holes are provided on the part of the connecting seat 2 corresponding to the countersunk holes.
[0040] It should be noted that this facilitates the connection between the housing 4 and the connecting seat 2, while the countersunk structure prevents interference between the components and screws inside the housing 4.
[0041] like Figure 3 As shown, the housing 4 has a first through hole in the middle for threading the cable 3, and the inner diameter of the first through hole is larger than the outer diameter of the cable 3. The cover plate 13 has a second through hole in the middle for threading the cable 3, and the inner diameter of the second through hole is larger than the outer diameter of the cable 3. A sealing ring 14 is installed on the inner side of the second through hole, and the sealing ring 14 abuts against the outer wall of the cable 3.
[0042] It should be noted that, while ensuring normal wire threading, the gap between the cable 3 and the cover plate 13 is filled by the sealing rubber ring 14 to prevent dust from entering the interior of the housing 4.
[0043] In use: First, put the housing 4 and the cover plate 13 on the cable 3 in sequence. Then, fix the housing 4 to the connecting seat 2. By using a tool with the cross groove 7 to screw the double-headed positive and negative screw 6, the connecting ear 10 will slide with the guide rod 5, and the two symmetrically arranged clamping plates 9 will move towards each other until the clamping plates 9 are tightly attached to the cable 3. This will achieve the function of fixing the cable 3, preventing the part of the cable 3 connected to the connecting seat 2 from being pulled during the use of the liquid-cooled charging gun body 1, preventing loosening and falling off, ensuring the normal use of the liquid-cooled charging gun, and avoiding the risk of electric shock.
[0044] By assembling a positioning seat 11 on the inner side of the adjustment groove 8, and embedding the cross protrusion 12 on the positioning seat 11 into the cross groove 7, and then fixing the positioning seat 11 to the inner side of the adjustment groove 8 with screws, the double-headed positive and negative screw 6 can be effectively prevented from loosening, thereby ensuring the stability of the clamping plate 9 clamping the cable 3. Finally, the cover plate 13 is fixed to the port of the housing 4.
[0045] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
