For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.
[0026] In one embodiment of this utility model, such as Figures 1-3 As shown, a USB protective case is provided, including an interface sleeve 1 and a connector sleeve 2, with the interface sleeve 1 connected to the connector sleeve 2.
[0027] The interface sleeve 1 includes an interface sleeve body 11 and a tail connector 12. The tail connector 12 is connected inside the interface sleeve body 11. The interface sleeve body 11 is provided with an interface hole 13, and the tail connector 12 is provided with a tail hole 14. The interface hole 13 is located on one side of the tail hole 14, and the interface hole 13 is connected to the tail hole 14.
[0028] The wiring sleeve 2 is located on one side of the interface sleeve body 11 and is connected to the interface sleeve body 11. The wiring sleeve 2 is provided with a wiring hole 21, which is located on one side of the tail hole 14. The wiring hole 21 is connected to the tail hole 14 and forms a wiring channel.
[0029] When a USB device is needed, first align the USB plug with the interface hole 13 on the interface sleeve 1. Since the interface hole 13 is connected to the tail hole 14, the USB plug can pass smoothly through the interface hole 13 and partially enter the area of the tail hole 14. The tail socket 12 plays a certain guiding and stabilizing role here, ensuring that the plug is accurately inserted and avoiding damage to the interface due to misinsertion.
[0030] Meanwhile, the connector sleeve 2, connected to one side of the interface sleeve body 11, also plays a role. The connector hole 21 on the connector sleeve 2 is also connected to the tail hole 14 to form a connector channel. The USB cable passes through the connector hole 21 along the connector channel and fits tightly around the tail hole 14. On the one hand, this tight fit prevents the USB cable from shaking or bending during insertion and removal, protecting the internal wires of the circuit and preventing circuit breakage due to frequent bending. On the other hand, the connector channel provides a relatively closed and stable space for the USB cable, isolating it from external dust, moisture and other impurities, preventing them from corroding the circuit, thereby ensuring the stability and reliability of USB data transmission and extending the service life of the USB device.
[0031] In another embodiment of this utility model, the interface hole 13 of the USB protective sleeve is square, with arc-shaped transition portions at the four corners. When a USB device is ready to be connected, the square interface hole 13 design can accurately adapt to the shape of common USB plugs. Compared with a circular hole, the square hole provides clear limits to the plug in the horizontal and vertical directions, making it less likely for the plug to shift or rotate during insertion, ensuring accurate insertion into the interface sleeve 1 in one go. The arc-shaped transition portions at the four corners play a clever role. On the one hand, during the insertion of the USB plug, the arc-shaped transition portions can effectively prevent the corners of the plug from colliding hard with the right angle of the interface hole 13, preventing damage to the edge of the interface hole 13 and extending the service life of the protective sleeve. On the other hand, it can also play a certain guiding function. Even if the plug insertion angle is slightly off, the arc-shaped transition portions can smoothly guide the plug to gradually straighten and smoothly enter the tail hole 14 area, further stabilizing the plug with the tail socket 12, greatly reducing the risk of misinsertion and protecting the interface from damage in all directions.
[0032] Simultaneously, the connector sleeve 2, which is tightly connected to the interface sleeve body 11, operates synchronously. The connector hole 21 on the connector sleeve 2 communicates with the tail hole 14 to form a connector channel. The USB cable passes through the connector hole 21 along this channel and fits tightly around the tail hole 14. This not only keeps the USB cable stable during plugging and unplugging, preventing it from shaking or bending and damaging the internal wires, but also eliminates the risk of circuit breakage and ensures the safe operation of the USB cable.
[0033] In another embodiment of this utility model, the USB protective sleeve has an arc-shaped tail hole 14. When the USB plug enters the tail hole 14 through the interface hole 13, the arc-shaped tail hole 14 perfectly fits the curved surface of the plug's rear end. Complementing the limiting function of the square hole, it stabilizes the plug from both ends, further limiting excessive wobbling and maintaining high stability when connected. Moreover, compared to other shapes, the arc-shaped tail hole 14 distributes friction more evenly on the plug during insertion and removal, reducing wear on the plug and tail hole 14 caused by excessive local friction and extending service life.
[0034] In another embodiment of this utility model, the wiring hole 21 of the USB protective sleeve is arc-shaped and extends through the sleeve 2. When the USB cable needs to be connected, the advantages of the arc-shaped through-hole 21 are evident. First, the arc shape complements the rounded outer sheath of the USB cable, reducing the risk of sharp edges scratching the cable sheath. During insertion and removal, it provides gentle protection for the USB cable, preventing damage to the outer sheath and ensuring the safety of the internal wires. Second, the through-hole design greatly facilitates the insertion and adjustment of the USB cable. No matter which direction the cable enters, the path can be easily found without the need for strenuous bending or twisting of the cable. This reduces operational difficulty and also minimizes the risk of internal damage to the wires caused by forced bending.
[0035] In another embodiment of this utility model, the side of the connector sleeve 2 of the USB protective sleeve is provided with positioning grooves 22. Multiple positioning grooves 22 are evenly distributed on the connector sleeve 2. This evenly distributed design makes the force distribution more balanced. Regardless of the direction of the external force, the multiple positioning grooves 22 work together to evenly distribute the external force to all parts of the USB cable, avoiding excessive pressure on any single point. This effectively protects the outer sheath of the USB cable from tearing and the internal wires from breaking, extending the service life of the USB cable. It ensures that the USB device can maintain efficient and reliable data transmission in complex and changing usage environments, such as mobile offices and outdoor operations, further strengthening the comprehensive protection system of the USB protective sleeve from the interface to the connector.
[0036] In another embodiment of this utility model, both the interface sleeve 1 and the connector sleeve 2 of the USB protective case are made of silicone. Silicone has excellent flexibility, so when the USB plug is inserted into the interface sleeve 1, the interface sleeve 1 will not cause hard pressure or scratches to the plug. On the one hand, the soft texture of silicone allows the four rounded transition portions of the square interface hole 13 to guide the plug in more smoothly, and even with repeated insertions and removals, the plug surface will not be damaged, effectively extending the service life of the USB plug; on the other hand, with the support of the silicone material, the rounded connector hole 14 fits more tightly and gently with the rear end of the plug, ensuring a stable connection while preventing wear.
[0037] For the connector sleeve 2, the flexibility of the silicone is equally crucial. The USB cable will not be hindered by the rigidity of the connector sleeve 2 during frequent plugging and unplugging, or by bending and twisting during daily use. The silicone cushioning around the arc-shaped through-hole 21 greatly reduces the risk of wear and tear on the USB cable's outer sheath, ensuring the internal wires remain intact and data transmission is consistently stable.
[0038] The USB protective sleeve provided in this application effectively prevents bending and damage at the connection point between the USB connector and the tail, thus improving its service life.
[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
