Description

Technical Field

[0001] The utility model belongs to the technical field of power adapters, and in particular relates to a power adapter with a long service life and a small volume. Background Art

[0002] Power adapters are power conversion devices for portable electronic devices and electronic appliances. Most of them are composed of a control system consisting of a transformer, capacitor, control IC and PCB board, and then covered with an outer shell. They have the function of converting AC input into DC output and are very common in charging devices for laptops and mobile phones.

[0003] In the power adapter used in laptop computers, the output end will be connected to the charging cable. However, when carrying the power adapter, most people will choose to comb the charging cable and then use a binding rope to wrap it to fix it. However, the wrapped charging cable still swings randomly, and the swinging charging head is prone to damage when it hits a hard object. The plug cable and the adapter body of the laptop power adapter adopt a separate design. When in use, the plug cable is inserted into the adapter port, but the adapter port is in an open state for a long time. When placed in a backpack, it is easy to get stuck in some tiny objects, making it easy for the plug end to be difficult to insert. Utility Model Content

[0006] Preferably, anti-slip grooves are provided on both sides of the adapter body, and an output line fixing block is provided at the root of the output power line.

[0007] Preferably, a charging head is installed at one end of the output power line away from the output line fixing block, and a movable binding rope is provided on the surface wall of the output power line.

[0008] Preferably, an opening cover is installed at the end of the adapter body located outside the power cord socket, and a pullable baffle is provided inside the opening cover.

[0009] Preferably, a limiting block is provided at one end of the baffle, and an end of the baffle away from the limiting block extends to the outside of the opening cover.

[0010] Preferably, a pull plate is installed at one end of the baffle away from the limiting block. When the baffle is fully pushed in, the opening of the mask is completely covered by the baffle. When the baffle is pulled out to the maximum distance, the power cord socket is completely exposed.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] (1) The utility model has an embedded groove on the surface wall of the adapter body, and a fixing rod is installed inside the embedded groove, and a strap that can surround the adapter body and the output power cord is installed outside the fixing rod. The surface wall of the strap is made of a fiber structure, and Velcro is installed on one side. When in use, the strap can be used to wrap the output power cord and the adapter body together, thereby preventing the charging head from colliding with hard objects due to the random swing of the output power cord when carrying the power adapter. Damage.

[0013] (2) The utility model provides an opening mask on the outside of the power cord socket, and a removable baffle is installed on the side of the opening mask, and a limit block is installed at the end of the baffle. When the plug power cord is not connected, the baffle can be pushed to block the opening of the opening mask, thereby isolating the power socket from the outside world and preventing foreign objects from being stuck inside the power cord socket when the power cord is not connected.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 and Figure 2 As shown, it includes an adapter body 2, the output end of the adapter body 2 is connected to the output power cord 5, and the input end of the adapter body 2 is provided with a power cord socket 7, the surface wall of the adapter body 2 is provided with an embedded groove 13, and a fixing rod 14 is installed inside the embedded groove 13, a strap 1 is arranged outside the embedded groove 13, and the strap 1 can be wound around the adapter body 2 and the output power cord 5, a Velcro 15 is arranged on the side wall of the end of the strap 1 away from the fixing rod 14, and the surface wall of the side of the strap 1 away from the Velcro 15 adopts a fiber structure that can be adsorbed by the Velcro 15.

[0021] Through the above technical solution;

[0022] The adapter body 2 can adopt the technical solution disclosed in the "power adapter" with application number CN201810105666.1. When fixing the output power cord 5, it is rolled up and attached to the edge of the adapter body 2, and then the strap 1 is pulled to wrap around the adapter body 2 and the output power cord 5. After winding it tightly, the output power cord 5 is fixed to the side of the adapter body 2 with the help of the adsorption force between the Velcro 15 and the limiting structure, thereby preventing the output power cord 5 from swinging easily when carrying.

[0023] See also Figure 1-Figure 4 As shown, an opening mask 10 is installed at the end of the adapter body 2, which is located on the outside of the power cord socket 7, and a pull-out baffle 9 is arranged inside the opening mask 10, a limiting block 8 is arranged at one end of the baffle 9, and the end of the baffle 9 away from the limiting block 8 extends to the outside of the opening mask 10, and a pull plate 11 is installed at the end of the baffle 9 away from the limiting block 8. When the baffle 9 is fully pushed in, the baffle 9 completely covers the opening of the opening mask 10, and when the baffle 9 is pulled out to the maximum distance, the power cord socket 7 is completely exposed.

[0024] Through the above technical solution;

[0025] The opening mask 10 and the baffle 9 are both made of tough plastic material. An empty slot for the baffle 9 to be pulled out is provided on the side of the opening mask 10. Due to the structural limitations of the limit block 8 and the pull plate 11, the baffle 9 cannot be completely pulled out. At the same time, a damping design can be adopted between the baffle 9 and the opening mask 10, and they will remain stagnant in place in the absence of external force. The damping effect can be produced by designing a larger baffle 9 so that it is clamped by the empty slot.

[0026] See also Figure 1-Figure 4 As shown, anti-slip grooves 12 are provided on both sides of the adapter body 2, and an output line fixing block 3 is provided at the root of the output power line 5. The output line fixing block 3 fixes the direction of the output power line 5 to prevent it from loosening due to excessive shaking during swinging.

[0027] A charging head 6 is installed at one end of the output power line 5 away from the output line fixing block 3, and a movable binding rope 4 is provided on the surface wall of the output power line 5. The binding rope 4 is wound around the output power line 5 and can slide arbitrarily on the surface wall of the output power line 5.

[0028] The working principle and use process of the utility model: when using the utility model, after the output power cord 5 is rolled up, the output power cord 5 is fixed with the binding rope 4. When carrying, the binding strap 1 is pulled open, and the root thereof is connected to the fixing rod 14 and fixed in the embedded groove 13, and it is wrapped around the adapter body 2 and the output power cord 5 and then rolled up, and finally fixed with the help of the Velcro 15, so as to prevent the output power cord 5 from swinging randomly. When the power adapter is placed in a backpack for carrying, the pull plate 11 is pushed so that the baffle 9 completely blocks the opening of the opening mask 10, so as to cover the power cord socket 7, so as to prevent small objects from getting stuck in the inside of the power cord socket 7 and affecting the wiring when placed in the backpack.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
