Description

Technical Field

[0001] The utility model relates to the technical field of charging cables, in particular to a multi-head charging cable. Background Art

[0002] Multi-connector charging cables, as highly integrated and multifunctional charging devices, are an outstanding example of the modern pursuit of an efficient and convenient lifestyle. They cleverly integrate multiple charging ports of varying specifications and power levels into one, allowing users to charge multiple electronic devices simultaneously, completely breaking away from the limitations of traditional charging cables that can only serve one device. In our fast-paced lives, people often own multiple electronic devices, such as smartphones, tablets, Bluetooth headsets, smartwatches, and laptops. These devices often require separate chargers and cables, causing inconvenience in daily life. The emergence of multi-connector charging cables is precisely to address this pain point. By integrating multiple charging ports into a single cable, users only need to carry a single cable to charge all their devices, significantly saving space and weight and making it easy to carry. Furthermore, multi-connector charging cables feature intelligent current distribution, automatically adjusting the output current and voltage according to the charging needs of different devices, ensuring that each device receives the optimal charging power. This ensures charging speed while avoiding safety hazards such as overcharging and overheating. This intelligent design provides users with convenient charging while providing greater peace of mind.

[0003] To sum up, the multi-head charging cable, with its highly integrated, multi-functional and intelligent features, has become an ideal choice for modern people pursuing an efficient and convenient lifestyle. It not only solves the many inconveniences brought by traditional charging methods, but also brings users a safer and more reliable charging experience through technological innovation.

[0004] In the process of implementing this solution, the inventors found that the following problems in the prior art have not been well solved: traditional multi-head data cables mostly have three heads. When in use, in most cases, the other two heads will be idle and exposed to the air. When charging, they are generally placed on the table. It is easy for the cup to overturn and cause water to contact the idle head, causing the head to be damaged and unable to continue to be used. Utility Model Content

The branch connection lines 13 are each provided with a charging terminal 14 at one end away from the main connection line 12. A protection mechanism 2 is provided at the position of the distribution terminal 11. The protection mechanism 2 includes a main protective shell 21, and the main protective shell 21 is located at the position of the distribution terminal 11 and has an end groove 22. The main protective shell 21 is located at the side of the end groove 22 close to the branch connection line 13 and has a bus groove 23. The inner wall of the bus groove 23 is bonded with a rubber sleeve 26. The main protective shell 21 A branching groove 24 is excavated on one side of the end groove 22 close to the branch connection line 13, and a rubber sleeve 25 is bonded inside the branching groove 24. The top of the main protective shell 21 is rotatably connected to the upper protective shell 27. Three branching grooves 211 are excavated on one side of the end where the main protective shell 21 and the upper protective shell 27 are close to each other. A connector groove 210 is excavated on one end of the main protective shell 21 and the upper protective shell 27 located inside the branching groove 211. An outer groove 28 is excavated on the outside of the top of the main protective shell 21 located at the position of the branching groove 211. An outer rubber 29 is provided on one end of the upper protective shell 27 located at the outer groove 28, and a semicircular rubber sleeve 212 is bonded to the inner wall of the branching groove 211.

[0024] Specifically, the distribution terminal 11 is embedded in the terminal groove 22, the end of the main connecting line 12 close to the distribution terminal 11 is connected to the second rubber sleeve 26, and the end of the branch connecting line 13 close to the distribution terminal 11 is connected to the first rubber sleeve 25.

[0025] Specifically, the end of the rubber sleeve 1 25 away from the end slot 22 extends to the outside of the branching slot 1 24 , and the end of the rubber sleeve 26 away from the end slot 22 extends to the outside of the bus slot 23 , thereby achieving a better protection effect.

[0026] Specifically, the outer diameter dimensions of the ends of the branch connecting wires 13 match the inner diameter dimensions formed between the two semicircular rubber sleeves 212 at the matching positions, and the connector grooves 210 are respectively located at the matching positions to match the sizes of the charging terminals 14. The ends of the two branch connecting wires 13 away from the distribution terminals 11 are respectively inserted into the two semicircular rubber sleeves 212 at the matching positions, and the charging terminals 14 are respectively embedded in the two connector grooves 210 at the matching positions, which have a protective effect on their storage, and the semicircular rubber sleeves 212 can protect the outer walls of the branch connecting wires 13.

[0027] Specifically, the upper protective shell 27 is inserted into the inner portion of the peripheral groove 28 , and the upper protective shell 27 contacts the side close to the main protective shell 21 to maintain the sealing and the stability between the main protective shell 21 and the upper protective shell 27 after the cover is closed.

[0028] Working principle: When only one of the charging terminals 14 is used, the upper protective shell 27 can be opened to expose the semicircular rubber sleeve 212. At this time, the idle branch connection line 13 can be bent to place the end of the charging terminal 14 in the connector groove 210 at the top of the main protective shell 21, and the branch connection line 13 close to the charging terminal 14 can be located at the branch groove 211. Then the upper protective shell 27 is rotated and closed with the main protective shell 21. At this time, the connector groove 210 at the position of the upper protective shell 27 will cover the upper half of the charging terminal 14 and match the main protective shell. The connector groove 210 on the upper shell 21 forms a wrapping effect on the charging terminal 14, and then the outer rubber 29 is inserted into the outer groove 28 to perform sealing protection to prevent moisture from entering and causing damage to the charging terminal 14. When the upper shell 27 and the main shell 21 are covered, the semicircular rubber sleeve 212 of the main shell 21 located in the second branch groove 211 will cover the outer wall of the lower end of the branch connection line 13 near one end of the charging terminal 14, and the semicircular rubber sleeve 212 of the upper shell 27 located in the second branch groove 211 will cover the branch connection line 13 near one end of the charging terminal 14. At the outer wall of the end, two semicircular rubber sleeves 212 are used to cover the branch connection line 13, so that moisture will not enter the interior of the connector groove 210 through the position of the branch groove 211, while the charging terminal 14 has the effect of upgrading the waterproof protection. At the same time, the shaking of the branch connection line 13 close to the charging terminal 14 can be protected by the semicircular rubber sleeve 212 to avoid touching the outer wall of the branch groove 211 and causing the rubber to be damaged. The distribution terminal 11 is located in the terminal groove 22 of the protection mechanism 2, and the main connection line 12 passes through the position of the bus groove 23. The wiring 13 can pass through the position of the branching groove 24, and when the main connecting line 12 and the branch connecting line 13 are in use and in the storage state and are bent, the outer wall is protected by the rubber sleeve 26 in the main groove 23 and the rubber sleeve 1 25 in the branching groove 24 when bending, avoiding the friction between the end of the main connecting line 12 and the branch connecting line 13 close to the distribution terminal 11 and the edge of the outer wall of the bus groove 23 and the branching groove 24, which may cause the rubber of the outer wall to be damaged, effectively protecting them and also playing a sealing role.
