Description

Technical Field

[0001] The utility model relates to the technical field of tram charging, in particular to a charging handle. Background Technique

[0002] The tram charging handle is the tram charging gun. The charging gun is a part connected to the charging pile and is used to transmit electricity to the vehicle's battery system. For traditional tram charging guns, there is no dust and waterproof device for protecting the plug part. If there is a lot of dust or residual rainwater on the plug part, safety accidents are likely to occur during use. Therefore, operators also need to check the plug part during use to ensure the safety of equipment use. Moreover, the tail of the charging gun is mostly directly connected to the charging pile through a connecting wire, and the sealing performance is poor, which is likely to affect the subsequent service life.

[0023] Please refer to Figures 1-5 , a charging handle, comprising a housing 1, a charging plug 2, control buttons 3, a seal and a protection component. The charging plug 2 is arranged on the front surface of the housing 1. The housing 1 is also provided with control buttons 3 for opening and closing the charging plug 2. A seal for wiring is further arranged on the rear side of the housing 1. A protection component for protecting the charging plug 2 is also arranged on the front surface of the housing 1. The seal includes a locking ring, a limiting ring 4 and a sealing head 5. The limiting ring 4 is arranged on the rear side of the housing 1. One end of the sealing head 5 is inserted into the limiting ring 4, and the other end of the sealing head 5 protrudes from the housing 1. A locking ring for fixing the sealing head 5 is also arranged on the limiting ring 4;

[0024] During actual use, the charging plug 2 is arranged on the front surface of the housing 1. A circuit board (not shown in the figure) connected to the charging plug 2, the control buttons 3 and the seal with a connecting wire is arranged in the housing 1. The connection relationship is a technical means well-known to those skilled in the art and will not be elaborated herein. The protection component is inserted into the charging plug 2 to provide protection against dust and water, which is convenient for disassembly and assembly. The connecting wire is connected to the sealing head 5. The sealing head 5 carries the connecting wire and is inserted into the limiting ring 4 on the rear side of the housing 1, and then fixed by the locking ring.

[0025] In this embodiment, the locking ring includes an upper half ring 6, a docking head 7, a lower half ring 8 and a bearing seat 9. A vertically penetrating docking hole is arranged in the middle of the contact part between the limiting ring 4 and the sealing head 5. Docking heads 7 are arranged on the left and right sides below the upper half ring 6. Bearing seats 9 for receiving the docking heads 7 are arranged on the left and right sides above the lower half ring 8. The two free ends above the lower half ring 8 are attached to the two free ends below the upper half ring 6. First, the sealing head 5 is inserted into the limiting ring 4, and the docking hole of the sealing head 5 is aligned with that of the limiting ring 4. Then, the docking head 7 of the upper half ring 6 is inserted into the docking hole, and the bearing seat 9 of the lower half ring 8 is inserted into the docking hole. The docking head 7 and the bearing seat 9 are inserted and connected. At this time, the connection between the sealing head 5 and the limiting ring 4 is fixed.

[0026] During actual use, in order to facilitate the limitation of the locking ring, in this embodiment, the outer diameter of the rear side of the housing 1 and the outer diameter of the rear side of the sealing head 5 are both larger than the outer diameter of the limiting ring 4. The outer diameter of the locking ring is adapted to the outer diameter of the rear side of the housing 1 and the outer diameter of the rear side of the sealing head 5.
