Description

Technical Field

[0001] The utility model relates to the technical field of charging, and specifically, to a charger with a sealed end. Background Art

[0002] A charger is a device that provides power replenishment for mobile phones or electronic devices. It usually consists of a plug, a connecting wire, and a charging interface. Its working principle is to convert mains power (alternating current power) into direct current suitable for charging the battery of an electronic device. The output voltage and current of the charger need to match the charging requirements of the electronic device to ensure safe and efficient charging of the electronic device. Nowadays, there are various types of electronic device chargers, such as traditional wired chargers, wireless chargers, etc. A wired charger connects to the mobile phone through a data cable to transmit power; a wireless charger uses the principle of electromagnetic induction and does not require a data cable connection. The electronic device only needs to be placed on the charger to charge. The quality and performance of the charger have an important impact on the lifespan and charging speed of the electronic device battery. A high-quality charger has functions such as overvoltage protection, overcurrent protection, and overheat protection, which can effectively ensure the safety of the charging process.

[0003] Existing chargers usually have exposed plug blades. During the process of plugging and unplugging with a power strip, if the hand touches the plug blades, there is a high possibility of electric shock. When the power strip gets wet, an electric shock accident is more likely to occur. Summary of the Utility Model

[0004] In order to overcome the above technical problems, the utility model provides a charger with a sealed end to improve the problem of the risk of electric shock during the plugging and unplugging of the charger.

[0005] To achieve the above purpose, the utility model proposes a charger with a sealed end, which includes a charging connector and plug blades installed on the charging connector. A movable end is slidably sleeved on the charging connector. An elastic device is provided in the inner cavity of the movable end, with one end abutted against the charging connector and the other end abutted against the inner cavity wall of the movable end. An opening is formed at the center of the end face of the movable end, and a end cover covers the opening. A through hole is formed on the end cover corresponding to the position of the end of the plug blade. An elastic sealing cover is provided in the orifice on the side of the through hole close to the end face. A flexible waterproof ring is formed on the end face of the movable end, which circumferentially surrounds the end cover and protrudes outward from the end face.

[0006] A movable end is sleeved on the charging connector. Before use, the plug pieces are retracted inside the movable end. When in use, the movable end first contacts the socket strip. The flexible waterproof ring plays a sealing role circumferentially to seal and isolate the movable end around the middle part. The charging connector slides downward, and the plug pieces pass through the inside of the through hole and closely fit with the elastic sealing cover, so that even if there is water, it cannot enter the inside of the movable end, ensuring that when the charging connector is inserted into or pulled out of the socket strip, the plug pieces are completely in a sealed state.

[0007] Preferably, a plurality of the flexible waterproof rings are provided.

[0008] Setting a plurality of flexible waterproof rings can play a role of multi-layer isolation, avoiding occasional leakage when the socket strip encounters water and preventing the risk of electric shock.

[0009] Preferably, a water absorption ring is formed on the end face of the movable end, which circumferentially surrounds the end cover and is located between the end cover and the flexible waterproof ring.

[0010] The function of setting the water absorption ring is that even if water enters the inside of the water absorption ring from the gap, it can be absorbed by the water absorption ring, further ensuring that the plug pieces do not come into contact with water.

[0011] Preferably, the water absorption ring is fitted with the movable end.

[0012] The water absorption ring is fitted with the movable end and can be detachably replaced. Once the water absorption ring comes into contact with water and absorbs moisture, it becomes a conductor. Therefore, the water absorption ring that has absorbed moisture needs to be replaced before the next use to keep the water absorption ring in a dry state.

[0013] Preferably, a wedge-shaped sealing strip protruding outward from the through hole is formed on the circumferential edge of the through hole.

[0014] When the plug pieces are inserted into the socket strip, the wedge-shaped sealing strip can be wedged into the edge gap of the socket of the socket strip, ensuring that water does not enter the socket of the socket strip when encountering water.

[0015] Preferably, the elastic device is a spring, a fixed column is provided inside the movable end, and the spring is sleeved outside the fixed column.

[0016] By providing a fixed column inside the movable end and sleeving a spring on the fixed column, when the movable end and the charging connector slide relative to each other, the spring will not shift its position, ensuring that the spring can be normally compressed and elastically released.

[0017] Preferably, elastic convex buttons are formed on the inner wall of the movable end in contact with the side wall of the charging connector, and grooves that are slidably and lockingly engaged with the elastic convex buttons are formed on the charging connector.

[0018] When the elastic convex buckle slides to the groove, it is embedded inside the groove. At this time, the movable end and the charging connector are locked. In this state, the plug piece completely retracts into the movable end, completely isolating the charging connector from the outside and ensuring the use safety.

[0019] The charger with a sealed end provided by the present utility model, by setting a movable end, when the charging connector is inserted into the socket strip, first seals the central area of the position of the plug piece, and then the charging connector moves downward, thereby driving the plug piece to pass through the through hole and insert into the socket strip. The internal area is sealed by a flexible waterproof ring to ensure the waterproof effect. Brief Description of the Drawings

[0025] The embodiments of the present utility model will be described below with reference to the drawings. The elements and features described in one drawing or one embodiment of the present utility model can be combined with the elements and features shown in one or more other drawings or embodiments. It should be noted that for the sake of clarity, the drawings and the description omit the representation and description of the components or processes that are irrelevant to the present utility model and are known to those of ordinary skill in the art.

[0026] The present utility model will be further described below with reference to the drawings.

[0027] As Figures 1 to 3As shown in the figure, the charger with a sealed end provided by the present utility model includes a charging connector 1 and a plug piece 2 installed on the charging connector 1. A movable end 3 is slidably sleeved on the charging connector 1. An elastic device 4 is provided in the inner cavity of the movable end 3, with one end abutted against the charging connector 1 and the other end abutted against the inner cavity wall of the movable end 3. An opening is formed at the center of the end face of the movable end 3, and a end cover 5 covers the opening. A through hole 6 is formed on the end cover 5 at a position corresponding to the end of the plug piece 2. An elastic sealing cover 7 is provided in the orifice on the side close to the end face of the through hole 6. A flexible waterproof ring 8 that circumferentially surrounds the end cover 5 and protrudes outward from the end face is formed on the end face of the movable end 3.

[0028] The movable end 3 is sleeved on the charging connector 1. Before use, the plug piece 2 is retracted inside the movable end 3. When in use, the movable end 3 first contacts the socket. The flexible waterproof ring 8 plays a sealing role circumferentially, sealing and isolating the middle part of the movable end 3. The charging connector 1 slides downward, and the plug piece 2 passes through the inside of the through hole 6 and closely fits with the elastic sealing cover 7. Even if there is water, it cannot enter the inside of the movable end 3, ensuring that when the charging connector 1 is inserted into or pulled out of the socket, the plug piece 2 is completely in a sealed state.

[0029] The elastic sealing cover 7 is two elastic strip-shaped blocking devices distributed on both sides of the orifice of the through hole 6. The material can be elastic rubber, which can automatically return to its original position after deformation and can closely fit the outer surface of the plug piece 2 when deformed, preventing water from flowing into the inside of the movable end 3. When the charger is not in use, due to the close fit of the elastic sealing cover 7, even if the plug piece 2 is wet, the surface moisture will be scraped off by the elastic sealing cover 7, preventing water from entering the inside of the movable end 3.

[0030] In addition, the elastic sealing cover 7 is provided on the end cover 5. Due to long-term use, the elastic sealing cover 7 may age. Therefore, replacing the end cover 5 can avoid the risk of water leakage due to the aging of the elastic sealing cover 7.

[0031] As shown in an embodiment of the present utility model, there are multiple flexible waterproof rings 8.

[0032] Setting multiple flexible waterproof rings 8 can play a role in multi-layer isolation, preventing occasional leakage when the socket gets wet and avoiding the risk of electric shock. The multi-layer isolation has a better water blocking effect.

[0033] As shown in an embodiment of the present utility model, a water absorption ring 9 that circumferentially surrounds the end cover 5 and is located between the end cover 5 and the flexible waterproof ring 8 is formed on the end face of the movable end 3.

[0034] The function of setting the water absorption ring 9 is that even if water enters the inside of the water absorption ring 9 from the gap, it can be absorbed by the water absorption ring 9, further ensuring that the plug piece 2 does not come into contact with water.

[0035] In an embodiment of the present utility model, it is shown that the water absorption ring 9 is in contact with the movable end 3.

[0036] The water absorption ring 9 is in contact with the movable end 3 and is detachable and replaceable. Once the water absorption ring 9 comes into contact with water and absorbs moisture, it becomes a conductor. Therefore, the water absorption ring 9 that has absorbed moisture needs to be replaced before the next use to keep the water absorption ring 9 in a dry state. The detachable water absorption ring 9 facilitates the maintenance of the movable end 3 and enables the movable end 3 to quickly return to a usable state.

[0037] In an embodiment of the present utility model, it is shown that a wedge-shaped sealing strip 10 protruding outward from the circumferential edge of the through hole 6 is formed on the circumferential edge of the through hole 6.

[0038] When the plug piece 2 is inserted into the socket strip, the wedge-shaped sealing strip 10 can be wedged into the edge gap of the socket of the socket strip, ensuring that water does not enter the socket of the socket strip in case of encountering water, thereby increasing the safety guarantee.

[0039] In an embodiment of the present utility model, it is shown that the elastic device 4 is a spring, and a fixed column 11 is provided inside the movable end 3, and the spring is sleeved outside the fixed column 11.

[0040] By providing the fixed column 11 inside the movable end 3 and sleeving the spring on the fixed column 11, when the movable end 3 slides relative to the charging connector 1, the spring will not shift its position, ensuring that the spring can be normally compressed and elastically released.

[0041] In an embodiment of the present utility model, it is shown that an elastic protruding buckle 13 is formed on the inner wall of the movable end 3 in contact with the side wall of the charging connector 1, and a groove 12 that slidably locks with the elastic protruding buckle 13 is formed on the charging connector 1.

[0042] When the elastic protruding buckle 13 slides to the groove 12 and is embedded inside the groove 12, at this time, the movable end 3 and the charging connector 1 are locked. In this state, the plug piece 2 is completely retracted into the movable end 3, completely isolating the charging connector 1 from the outside, ensuring the use safety and also preventing the movable end 3 from falling off when the charging connector 1 is pulled out.

[0043] For the charger with a sealed end provided by the present utility model, by providing the movable end 3, when the charging connector 1 is plugged into the socket strip, the central area of the position of the plug piece 2 is first sealed, and then the charging connector 1 moves downward, thereby driving the plug piece 2 to pass through the through hole 6 and insert into the socket strip. The internal area is sealed by the flexible waterproof ring 8 to ensure the waterproof effect.

[0044] Although the present utility model and its advantages have been described in detail, it should be understood that various changes, substitutions and alterations can be made without departing from the spirit and scope of the present utility model as defined by the appended claims.
