Description

Technical Field

[0001] This application relates to the field of connectors, and particularly to a dust-proof charging connector. Background Art

[0002] As a key electrical connection component, in some scenarios, the secondary locking mechanism of a forklift connector is often designed in an exposed form. Although this design facilitates intuitive locking and unlocking operations for operators, it also exposes a significant defect: that is, the sliding position of the lock directly faces the external environment. Due to the complex use environment of the dust-proof charging connector, foreign matters such as cement and dust are likely to exist. These foreign matters will gradually accumulate and cause wear, jamming or corrosion of the locking mechanism, thereby affecting the normal sliding operation of the secondary lock.

[0003] Therefore, in some existing technologies, measures are taken to additionally provide a dust-proof cover outside the connector. However, the installation and disassembly of the dust-proof cover increase the operation complexity and reduce the work efficiency.

[0004] Therefore, this application studies a dust-proof charging connector that can conveniently protect the inside of the secondary lock, prevent dust and the like from entering, enhance the environmental adaptability of the connector such as dust-proof ability, and extend the service life of the connector.

Detailed implementation manners

[0032] The following further describes the present application in detail with reference to the Figures 1-7 accompanying drawings.

[0033] An embodiment of the present application discloses a dust-proof charging connector. Referring to Figure 1 , the dust-proof charging connector includes a socket assembly 1, a plug assembly 2, a buckle 3, a ferrule 4, and a secondary lock 5, the buckle 3 is integrally installed on the plug assembly 2, and the ferrule 4 is integrally installed on the socket assembly 1.

[0034] Referring to Figure 1 and Figure 2 , the secondary lock 5 includes a mounting member 51 and an abutting member 52. The mounting member 51 is integrally connected to the socket assembly 1 and is provided with a sliding groove 6. The abutting member 52 is sleeved on the mounting member 51 and is slidably connected to the mounting member 51. When the socket assembly 1 and the plug assembly 2 are engaged, the buckle 3 is clamped to the ferrule 4, the abutting member 52 abuts between the buckle 3 and the socket assembly 1, the abutting member 52 covers the sliding groove 6, and the mounting member 51 and the abutting member 52 are in clearance fit with a clearance not exceeding 0.1 mm, which can effectively prevent dust with a diameter greater than 0.1 mm from entering the cavity. At the same time, it can resist the impact of water droplets from the front, side, upper and lower surfaces, and can reach the IP41 dust and water protection level, which can effectively protect the inside of the secondary lock 5, prevent dust, muddy water, etc. from entering, enhance the dust and water protection and other environmental adaptability of the connector, and extend the service life of the connector.

[0035] Referring to Figure 3 , in some embodiments, fixed edges 13 are integrally provided on both sides of the abutting member 52, and fixing grooves 21 are provided on both sides of the mounting member 51. The fixed edges 13 are slidably limited within the fixed edges 13. Through the cooperation of the fixed edges 13 and the fixing grooves 21, the abutting member 52 can be limited and fixed to the mounting member 51.

[0036] Referring to Figure 2 and Figure 4In some embodiments, the abutment member 52 is connected to a first elastically deformable limiting portion 7. In this embodiment, two first limiting portions 7 are provided at intervals, forming a first limiting groove 9, a second limiting groove 10, and a third limiting groove 11. The sliding groove 6 is divided into a first sliding section 61, a second sliding section 62, and a third sliding section 63. The walls of the sliding groove 6 are provided with a first engaging portion 8 that cooperates with the first limiting portion 7. In this embodiment, the sidewalls of the first sliding section 61 and the second sliding section 62 are integrally provided with the first engaging portion 8. The two first limiting portions 7 are located within the first sliding section 61 and the second sliding section 62, respectively, and the two first engaging portions 8 are located within the first limiting groove 9 and the third limiting groove 11, respectively. The first limiting portions 7 and the first engaging portions 8 correspond one-to-one. When the socket assembly 1 is mated with the plug assembly 2, the first limiting portion 7 engages with the side of the first engaging portion 8 facing the plug assembly 2, thereby better positioning the abutment member 52 to support the buckle 3.

[0037] In some embodiments, the first limiting portion 7 is provided with a deformation groove 12. The deformation groove 12 allows the first limiting portion 7 to deform. When the abutment member 52 is pushed along the sliding groove 6, the first limiting portion 7 is deformed by the deformation groove 12 due to the force of the first clamping portion 8 and slides to a corresponding position within the sliding groove 6.

[0038] Reference Figure 5 In some embodiments, when the socket assembly 1 and the plug assembly 2 are not mated, the first limiting portion 7 is engaged with the side of the first engaging portion 8 facing away from the plug assembly 2. In this embodiment, the first limiting portion 7 abuts against the wall of the sliding groove 6, so that the first limiting portion 7 is limited between the wall of the sliding groove 6 and the first engaging portion 8. This allows the abutting member 52 to be better positioned when not in use.

[0039] Reference Figure 6 In some embodiments, the abutment member 52 is also integrally connected to the second limiting portion 14, Figure 4 In this embodiment, the second limiting portion 14 is located within the second limiting groove 10. The second engaging portion 15 is integrally connected to the socket assembly 1. In this embodiment, the second engaging portion 15 is located within the second sliding section 62, and the second limiting portion 14 slides within the second sliding section 62. When the socket assembly 1 is mated with the plug assembly 2, the second limiting portion 14 abuts against the side of the second engaging portion 15 facing away from the plug assembly 2.

[0040] Continue to refer to Figure 6 In some embodiments, the dustproof charging connector further includes a first sealing ring 16, which is sleeved on the plug assembly 2; when the socket assembly 1 is mated with the plug assembly 2, the outer peripheral side of the first sealing ring 16 abuts against the inner peripheral side of the socket assembly 1, so that the dustproof charging connector can be better protected from dust and water, etc., thereby better protecting the interior of the dustproof charging connector and extending its service life.

[0041] In some embodiments, grooves 17 are spaced apart on both sides of the first sealing ring 16, and convex portions 18 are formed. In this embodiment, two grooves 17 are provided on each side, forming three convex portions 18. The convex portions 18 on both sides of the first sealing ring 16 respectively abut against the socket assembly 1 and the plug assembly 2. When the socket assembly 1 and the plug assembly 2 are fitted, the grooves 17 can provide a space for the convex portions 18 to give way, so that the convex portions 18 can better fit into the gaps between the socket assembly 1 and the plug assembly 2, playing a better sealing role.

[0042] Refer to Figure 7 . The figure shows one side of the socket assembly 1. The same applies to one side of the plug assembly 2 as that of the socket assembly 1. The dust-proof charging connector further includes a second sealing ring 19. The socket assembly 1 and the plug assembly 2 are both provided with cable insertion ports 20. The second sealing ring 19 is arranged at the cable insertion ports 20, so that when the cable is inserted, the cable can fit into the gap between the cable and the second sealing ring 19, preventing foreign matters such as dust and water from entering the dust-proof charging connector, so as to better protect the dust-proof charging connector and extend its service life.

[0043] The implementation principle of a dust-proof charging connector according to an embodiment of the present application is as follows: During installation, the socket assembly 1 and the plug assembly 2 are fitted. By the abutting member 52 abutting against the buckle 3, the buckle 3 can be made more stable. At the same time, the abutting member 52 can also cover the sliding groove 6 and can resist the impact of water droplets from the front, side, upper and lower surfaces, reaching the IP41 dust-proof and waterproof level, effectively protecting the inside of the secondary lock 5, preventing dust and the like from entering, enhancing the environmental adaptability of the connector such as dust-proof and waterproof, and extending the service life of the connector.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered by the protection scope of the present application.
