Description

Technical Field

[0001] This utility model relates to the field of charging gun connector technology, and more specifically, to a waterproof connector that can fix multiple standard charging guns. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the construction and improvement of charging infrastructure has become a key support for promoting the industry's popularization. Among them, the charging gun, as the core component connecting the charging pile and the vehicle, has its connector stability, sealing and compatibility directly affecting charging safety and user experience.

[0003] This application improves upon existing technologies. Currently, there are various specifications of charging guns on the market, and the diameters of charging gun harnesses differ between different brands and models. Existing charging pile connectors generally adopt a fixed aperture structure design, which can only adapt to a single specification of charging gun harness. When it is necessary to replace or adapt to charging guns of different standards, the corresponding connector components must be replaced, which not only increases the cost of use but also reduces the universality of charging facilities, making it difficult to meet the flexible use needs in multiple scenarios. In terms of installation and fixing, the connection between traditional charging gun connectors and charging piles mostly relies on bolt tightening. Bolt tightening requires the use of special tools and is carried out step by step, resulting in low installation efficiency. Moreover, after long-term use, the bolts are prone to loosening due to vibration, affecting the connection stability. Utility Model Content

The two sides of the fixing ring pieces 3 are threadedly connected to fixing screws 4. A fixing soft ring 13 abuts between the two fixing ring pieces 3. The end of the fixing soft ring 13 extending out of the bottom of the fixing base 1 is fixedly connected to an installation piece 5, and the installation piece 5 abuts against the fixing base 1. A connecting sleeve 8 is fixedly connected to the side of the installation piece 5 away from the fixing base 1. A connecting ring 9 is slidably connected to the outer wall of the connecting sleeve 8. The two outer walls of the connecting sleeve 8 are slidably connected to symmetrically distributed locking blocks 23, and the locking blocks 23 are engaged with the connecting ring 9. By moving and squeezing the fixing soft ring 13 through the two fixing ring pieces 3, the fixing soft ring 13 is tightly fitted with the charging gun wire harness to fix wire harnesses of different diameters. The locking blocks 23 are engaged with the connecting ring 9 to facilitate the fixing of the connector when installed on a charging pile.

[0023] The inner wall of the connecting ring 9 and the outer wall of the connecting sleeve 8 adopt a transition fit, and the outer wall of the connecting ring 9 and the mounting hole of the charging pile housing 16 adopt a clearance fit, which ensures smooth assembly and prevents the connecting ring 9 from shaking during use.

[0024] The connecting sleeve 8 has symmetrically distributed sliding grooves 18 on its two outer walls. The inner wall of the sliding groove 18 is slidably connected to the locking block 23, and the sliding groove 18 guides the movement of the locking block 23.

[0025] The inner wall of the slide 18 is fixedly connected to a guide rod 19, and the guide rod 19 is slidably connected to the locking block 23. One end of the guide rod 19 that extends into the locking block 23 is fixedly connected to a limiting block 21. A guide groove 22 is provided in the locking block 23, and the inner wall of the guide groove 22 is slidably connected to the limiting block 21. The limiting block 21 limits the locking block 23 to prevent the locking block 23 from separating from the slide 18.

[0026] One end of the locking block 23 that extends into the slide groove 18 is fixedly connected to a spring 20, and the other end of the spring 20 is fixedly connected to the inner wall of the slide groove 18. The spring 20 is sleeved with the guide rod 19, and the spring 20 facilitates the extension of the locking block 23 so that the locking block 23 can be engaged with the connecting ring 9.

[0027] The connecting ring 9 has symmetrically distributed slots 24 on the side away from the fixed base 1, and the slots 24 are adapted to the locking block 23. The inner wall of the connecting ring 9 has symmetrically distributed positioning grooves 10. The outer walls of both sides of the connecting sleeve 8 are fixedly connected with symmetrically distributed positioning blocks 11, and the positioning blocks 11 are adapted to the positioning grooves 10. The positioning blocks 11 and the positioning grooves 10 facilitate the positioning of the connecting ring 9 during installation, thereby ensuring that the locking block 23 can enter the slot 24.

[0028] The charging pile housing 16 is abutted between the connecting ring 9 and the mounting piece 5. The charging pile housing 16 has an installation groove 12, which is adapted to the connecting sleeve 8 and the positioning block 11. A sealing groove 17 is provided on the side of the charging pile housing 16 near the mounting piece 5.

A sealing gasket 7 is fixedly connected to the side of the installation ring 6 away from the mounting piece 5. The joint is sealed after installation through the installation ring 6, the sealing gasket 7 and the sealing groove 17.

[0029] The mounting ring 6 and the sealing gasket 7 are made of nitrile rubber and fluororubber, respectively. After molding, the peel strength of the two is ≥5N / mm, ensuring that they will not fall off during long-term use.

[0030] The fixing ring 3 has symmetrically distributed second screw holes 15 on both sides, and the second screw holes 15 are adapted to the fixing screws 4. The fixing block 2 has first screw holes 14 on both sides, and the first screw holes 14 are adapted to the fixing screws 4. The first screw holes 14 facilitate the entry of the fixing screws 4 to fix the fixing ring 3.

[0031] Working principle and usage process of this utility model:

[0032] In this application, during installation, pushing the connector causes the connecting sleeve 8 to enter the mounting groove 12 on the charging pile housing 16, causing the positioning block 11 to enter the mounting groove 12. The fixing seat 1 is located on the outside of the charging pile housing 16, and the connecting ring 9 is located on the inside of the charging pile housing 16. Pushing the connecting ring 9 causes the positioning block 11 to enter the positioning groove 10. When the connecting ring 9 moves, the locking block 23 enters the sliding groove 18, and the spring 20 contracts. When the connecting ring 9 moves to abut against the charging pile housing 16, the spring 20 returns to its original position. The spring 20 drives the locking block 23 to move, causing the locking block 23 to extend and enter the locking groove 24 to limit the connection ring 9. The mounting ring 6 and the sealing gasket 7 enter the sealing groove 17 to achieve a seal, which facilitates installation.

[0033] In this application, when installing the charging gun, the charging gun's wiring harness is passed through the waterproof connector's fixing soft ring 13 inside the connecting sleeve 8. The fixing soft ring 13 is fixed using the fixing ring plates 3 on both sides and the fixing screws 4. By adjusting the tightness between the fixing screws 4 and the two fixing ring plates 3, the fixing soft ring 13 is reasonably squeezed, thereby completing a safe and reliable fixation of the charging gun's wiring harness.
