Description

Technical Field

[0001] The utility model relates to the technical field of charging plugs, and particularly relates to a waterproof pile-end European standard charging plug. Background Technique

[0002] For new energy vehicles, a charging gun for charging is equipped. The charging gun is divided into two parts: a charging head and a connecting wire. The charging head is electrically connected to the output wire of the charging pile through the connecting wire. When the charging head is in use, charging can be completed by plugging it into the charging port of the new energy vehicle.

[0003] The outer shells of common European standard charging guns are combined in a splicing manner, such as left-right half or up-down half. This splicing outer shell structure not only reduces the overall structural strength of the charging gun outer shell, making it unable to withstand accidental rolling of the vehicle, but also there are multiple gaps in the charging gun outer shell, and the waterproof performance is poor. Rainwater will enter the gun through the gaps and cause damage to the internal wire harness. Summary of the Invention

[0004] The purpose of the utility model is to provide a waterproof pile-end European standard charging plug to solve the above-mentioned defects in the prior art.

[0005] A waterproof pile-end European standard charging plug includes a charging outer plastic shell and a sub-sealing shell. On one side of the charging outer plastic shell, multiple groups of alignment columns are distributed in a rectangular shape. A columnar head is connected through one side of the charging outer plastic shell. A protection mechanism is arranged on the outer side of the charging outer plastic shell. The protection mechanism shields the outer joint of the charging outer plastic shell and at the same time avoids hard contact between the charging outer plastic shell and the ground during the falling process, causing damage to the charging outer plastic shell. A positioning mechanism is arranged inside the charging outer plastic shell. The positioning mechanism clamps wires with different diameters inside the charging outer plastic shell, avoids the wires from shaking during the docking process, and avoids the rubber skin from being corroded due to water vapor infiltration.

[0006] Preferably, the protection mechanism includes a rectangular frame, a corrugated rubber sleeve, a rubber sleeve, a sliding groove, a guiding block and a fastener. The rectangular frames are symmetrically installed on both sides of the charging outer plastic shell. The corrugated rubber sleeve is attached to the outer side of the rectangular frame. The rubber sleeve is connected to the other side of the charging outer plastic shell. Sub-sealing shells are symmetrically arranged on the outer side of the charging outer plastic shell. The guiding blocks are symmetrically connected to the bottom end of the rectangular frame. The fastener penetrates through the top end of the guiding block.

[0007] Preferably, the sub-sealing shell is connected to the outer side of the guiding block through the symmetrically arranged sliding grooves on the outer side.

[0008] Preferably, the positioning mechanism includes a split seal housing, a card slot, a wire support plate, a wire clamping plate, and a guide rod. A card slot is provided on one side of the split seal housing. A wire support plate is welded to one side of the split seal housing. Wire clamping plates are arranged on both the upper and lower sides of the wire support plate. The outer sides of the wire clamping plates are connected through the guide rods, and the bottom ends of the guide rods are connected to both the upper and lower sides of the wire support plate.

[0009] Preferably, the wire support plate is connected to two groups of wire clamping plates through symmetrically arranged guide rods.

[0010] Preferably, the split seal housing is connected to another group of split seal housings through the card slot provided on one side.

[0011] Compared with the prior art, the present utility model has the following advantages:

[0012] 1. During use, the outer sides of the two groups of split seal housings are clamped and positioned by the rectangular frame. The distance between the rectangular frames is adjusted according to the size of the split seal housing, and then the outer sides of the two groups of split seal housings are fastened to prevent the gap generated after the split seal housings are clamped from increasing due to collision, or even causing the two groups of split seal housings to separate. The two sides of the corrugated rubber sleeve are positioned by the symmetrically arranged rectangular frames to prevent the corrugated rubber sleeve from loosening during use.

[0013] 2. At the same time, the wire support plate and wire clamping plate arranged inside the split seal housing are used to separate and position wire harnesses with different diameters, thereby ensuring the stability of the wire harnesses during installation and use. At the same time, the wire support plate and wire clamping plate are used to support the inside of the split seal housing to prevent the split seal housing from being damaged due to extrusion during long-term use. The wire harnesses can be disassembled and clamped and positioned by adjusting the distance between the wire support plate and the wire clamping plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] As Figures 1 to 5 shown, a waterproof pile-end European standard charging plug includes a charging outer plastic shell 1 and a sub-sealing shell 8. On one side of the charging outer plastic shell 1, multiple groups of alignment posts 2 are distributed in a rectangular pattern. A columnar head 7 is connected through one side of the charging outer plastic shell 1. A protection mechanism 5 is arranged on the outer side of the charging outer plastic shell 1. The protection mechanism 5 shields the outer joint of the charging outer plastic shell 1, and at the same time avoids the hard contact between the charging outer plastic shell 1 and the ground during the falling process, causing damage to the charging outer plastic shell 1. A positioning mechanism 10 is arranged inside the charging outer plastic shell 1. The positioning mechanism 10 clamps wires with different diameters inside the charging outer plastic shell 1, avoids the wires from shaking during the docking process, and avoids the corrosion of the rubber caused by the infiltration of water vapor.

[0023] In this embodiment, the protection mechanism 5 includes a rectangular frame 3, a corrugated rubber sleeve 4, a rubber sleeve 6, a slide groove 11, a guide block 12 and a fastener 13. The rectangular frames 3 are symmetrically installed on both sides of the charging outer plastic shell 1. The corrugated rubber sleeve 4 is attached to the outer side of the rectangular frame 3. A rubber sleeve 6 is connected to the other side of the charging outer plastic shell 1. Sub-sealing shells 8 are symmetrically arranged on the outer side of the charging outer plastic shell 1. Guide blocks 12 are symmetrically connected to the bottom end of the rectangular frame 3. Fasteners 13 are connected through the top ends of the guide blocks 12. The length of the corrugated rubber sleeve 4 is selected according to the length of the charging outer plastic shell 1.

[0024] In this embodiment, the sub-sealing shell 8 contacts the outer side of the guide block 12 through the slide grooves 11 symmetrically opened on the outer side, improving the contact friction of the rectangular frame 3, and using the rectangular frame 3 and the sub-sealing shell 8 for locking and positioning.

[0025] In this embodiment, the positioning mechanism 10 includes a split sealing case 8, a card slot 9, a wire support plate 14, a wire clamping plate 15 and a guide rod 16. A card slot 9 is provided on one side of the split sealing case 8. A wire support plate 14 is welded to one side of the split sealing case 8. Wire clamping plates 15 are arranged on both the upper and lower sides of the wire support plate 14. The outer sides of the wire clamping plates 15 are penetrated and connected with a guide rod 16. The bottom end of the guide rod 16 is connected to both the upper and lower sides of the wire support plate 14.

[0026] In this embodiment, the wire support plate 14 is connected to two groups of wire clamping plates 15 through symmetrically arranged guide rods 16. The two sides of the wire support plate 14 are positioned through the guide rods 16 to prevent the wire support plate 14 from being misaligned.

[0027] In this embodiment, the split sealing case 8 is connected to another group of split sealing cases 8 through the card slot 9 provided on one side. The outer sides of the split sealing cases 8 are docked through the card slot 9, improving the flexibility of the assembly and positioning of the split sealing cases 8.

[0028] When this waterproof pile-end European standard charging plug is actually applied, it includes the following working contents:

[0029] Step 1: The operator first docks the groove provided on one side of the split sealing case 8 with the protruding part on the other side of another group of split sealing cases 8, thereby completing the snap connection of the two groups of split sealing cases 8. Then, the rectangular frame 3 is inserted into the interior of the split sealing case 8. At the same time, the guide block 12 provided at the bottom end of the rectangular frame 3 is fitted with the chute 11 provided on the outer side of the split sealing case 8. The distance between the two groups of rectangular frames 3 is adjusted according to the length of the charging outer plastic shell 1. At the same time, the corrugated rubber sleeve 4 is installed on the outer side of the rectangular frame 3, and then the outer side of the charging outer plastic shell 1 is wrapped by the corrugated rubber sleeve 4.

[0030] Step 2: The outer side of the charging outer plastic shell 1 is covered by the corrugated rubber sleeve 4 to prevent rainwater from the outside from seeping into the gaps of the charging outer plastic shell 1. Multiple groups of wire harnesses are directly inserted into the interior of the rubber sleeve 6, so that the wire harnesses are inserted into the interior of the charging outer plastic shell 1. By pressing down the wire clamping plate 15, the wire clamping plate 15 and the wire support plate 14 clamp wire harnesses of different diameters. The two sides of the wire clamping plate 15 are guided by the guide rod 16 to prevent the wire clamping plate 15 from being misaligned during the lifting and lowering process. The contact surface between the wire clamping plate 15 and the wire support plate 14 is locked by bolts.

[0031] Step 3: Insert the metal end of the wire harness into the access end on one side of the columnar head 7, then install the columnar head 7 on one side of the charging outer plastic shell 1, and align the power connection end with the alignment posts 2 distributed in a rectangle. The primary coil of the transformer converts 220V AC mains into 16V alternating current, and then converts it into a DC voltage through the rectification of the rectifier. The charging outer plastic shell 1 is wrapped by the corrugated rubber sleeve 4 to prevent the corrugated rubber sleeve 4 from protecting the outside of the charging outer plastic shell 1 after the operator loosens the charging outer plastic shell 1.

[0032] Therefore, the above-disclosed embodiments are illustrative in all respects and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
