Description

Technical Field

[0001] This utility model relates to the field of USB connector technology, specifically a USB connector with protective function. Background Technology

[0002] USB connectors are a common interface for electronic devices. Their professional name is Universal Serial Bus, which is a way to connect electronic products to each other. It is used in various types of devices such as mobile, audio-visual, automotive electronics, multimedia, and electrical appliances, and has been widely adopted in various external devices.

[0003] A search revealed patent CN221407771U, which discloses a dustproof USB connector. This connector utilizes a hollow shell, cover plate, insert strip, pad, U-shaped sealing gasket, spring, slide plate, horizontal bar, and vertical plate to seal the plug connection when the USB connector is not in use. This prevents dust from entering the plug, reducing induction and contact problems. It also prevents damage to the exposed plug when not in use, improving the connector's protection. Furthermore, it is easy to use, enhancing the connector's reliability and practicality. However, the device is open on the sides, only protecting the inside of the USB connector. Dust can accumulate around the connector, affecting its use, and it lacks waterproofing. Therefore, we propose a USB connector with a protective function. Utility Model Content

[0004] The purpose of this invention is to provide a USB connector with protective functions.

[0005] To address the problems mentioned in the background art, this utility model provides the following technical solution: a USB connector with protective function, comprising a connector housing, a connecting plate mounted on the left side of the connector housing, a USB connector head mounted on the left side of the connecting plate, a first sliding box and a second sliding box mounted on the front and back of the connector housing respectively, a first sliding plate mounted on the inner side of the first sliding box, a connecting post mounted on the left side of the first sliding plate, a first spring sleeved on the outer side of the connecting post, a rotating block mounted on the left side of the connecting post, a protective shell mounted on the front of the rotating block, a locking block mounted on the front of the protective shell, a second sliding plate mounted on the inner side of the second sliding box, a slider mounted on the left side of the second sliding plate, a second spring sleeved on the outer side of the slider, and a pull plate mounted on the left side of the slider.

[0006] Preferably, the connecting column is slidably connected to the first slide box, and the second slide plate is slidably connected to the second slide box.

[0007] Preferably, a slot is provided on the left side of the front of the first slide box, and the slot is slidably connected to the rotating block.

[0008] Preferably, a first sealing ring is fixedly connected to the left side of the connecting plate, and a first sealing ring is fixedly connected to the right side of the protective shell.

[0009] Preferably, mounting blocks are provided through the upper and lower ends of the connector housing. A first extrusion plate and a second extrusion plate are respectively installed on the inner side of the mounting blocks. A third spring is provided at the lower end of the first extrusion plate. A silicone pad is installed at the lower end of the third spring. An internal component is provided on the inner side of the silicone pad. A fourth spring is provided at the upper end of the second extrusion plate.

[0010] Preferably, a protective plate is fixedly connected to the outer side of each mounting block, and a second sealing ring is provided through the upper and lower ends of the connector housing.

[0011] Preferably, the mounting block passes through the second sealing ring, and the second sealing ring is slidably connected to the mounting block.

[0012] Using the above technical solution, by pulling the protective shell, the first sliding plate is moved to the left inside the first sliding box under the cooperation of the rotating block and the connecting column, so that the right side of the protective shell exceeds the left side of the USB connector. Then, by pulling the pull plate, the second sliding plate is moved to the left inside the second sliding box under the cooperation of the slider, so that the right side of the pull plate exceeds the left side of the USB connector. At this time, the protective shell is rotated, so that the protective shell drives the locking block to rotate to the back, so that the locking block engages with the slider. Then, the protective shell and the pull plate are released, so that the first and second sliding plates move to the right under the cooperation of the first and second springs, respectively, so that the protective shell wraps the USB connector inside. Conversely, by opening it, the first sealing ring prevents external liquid from contacting the USB connector through the gap between the protective shell and the USB connector, so that the USB connector with protective function can be isolated from external dust and liquid, so that the USB connector with protective function will not be damaged.

[0013] By employing the above technical solution, when the connector housing is dropped, the protective plate collides with the ground. In this collision, the protective plate, in conjunction with the mounting block, impacts the first or second compression plate, which in turn impacts the third or fourth spring. The elasticity of the third or fourth spring buffers the impact force. This buffered impact force is then further neutralized by the silicone pad, preventing damage to the internal components encased within the silicone pad. Furthermore, the second sealing ring prevents liquid from the ground from entering the connector housing when the mounting block slides. This protective USB connector cushions the impact upon drop, preventing damage to internal components and extending its lifespan. Attached Figure Description

Detailed Implementation

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] Example 1:

[0021] Please see Figure 1-4This utility model provides a technical solution: a USB connector with protective function, including a connector housing 1, a connecting plate 2 installed on the left side of the connector housing 1, a USB connector head 3 installed on the left side of the connecting plate 2, a first sliding box 4 and a second sliding box 11 installed on the front and back of the connector housing 1 respectively, a first sliding plate 5 installed on the inner side of the first sliding box 4, a connecting post 6 installed on the left side of the first sliding plate 5, a first spring 7 sleeved on the outer side of the connecting post 6, a rotating block 8 installed on the left side of the connecting post 6, a protective shell 9 installed on the front of the rotating block 8, a locking block 10 installed on the front of the protective shell 9, a second sliding plate 12 installed on the inner side of the second sliding box 11, a slider 13 installed on the left side of the second sliding plate 12, a second spring 14 sleeved on the outer side of the slider 13, and a pull plate 15 installed on the left side of the slider 13.

[0022] The connecting column 6 is slidably connected to the first sliding box 4, and the second sliding plate 12 is slidably connected to the second sliding box 11.

[0023] The first slide box 4 has a slot on the left side of its front, and the slot is slidably connected to the rotating block 8.

[0024] The first sealing ring 16 is fixedly connected to the left side of the connecting plate 2, and the first sealing ring 16 is fixedly connected to the right side of the protective shell 9.

[0025] In use, by pulling the protective shell 9, the protective shell 9 moves the rotating block 8 to the left. As the rotating block 8 moves, it pulls the first sliding plate 5 to the left inside the first sliding box 4 via the connecting post 6. At this time, the first sliding plate 5 compresses the first spring 7, causing the right side of the protective shell 9 to extend beyond the left side of the USB connector 3. Then, pulling the pull plate 15 causes the right-side slider 13 to move. As the slider 13 moves, it pulls the second sliding plate 12 to the left inside the second sliding box 11, causing the second sliding plate 12 to compress the second spring 14. This causes the right side of the pull plate 15 to extend beyond the left side of the USB connector 3. At this point, rotating the protective shell 9 causes the card... The block 10 is rotated to the back, causing the locking block 10 to engage with the slider 13. At this time, the protective shell 9 and the USB connector 3 remain parallel. Then, the protective shell 9 and the pull plate 15 are released, causing the first slide plate 5 and the second slide plate 12 to move to the right inside the first slide box 4 and the second slide box 11 under the elasticity of the first spring 7 and the second spring 14, respectively. This allows the protective shell 9 to enclose the USB connector 3 inside. At this time, the first sealing ring 16 on the right side of the protective shell 9 and the left side of the connecting plate 2 will fit tightly, preventing external liquid from contacting the USB connector 3 through the gap between the protective shell 9 and the USB connector 3. This allows the USB connector with protective function to be isolated from external dust and liquid, preventing damage to the USB connector with protective function.

[0026] Example 2:

[0027] Please see Figure 1-4 This utility model provides a technical solution: a USB connector with protective function, wherein mounting blocks 17 are provided through the upper and lower ends of the connector shell 1, a first extrusion plate 19 and a second extrusion plate 24 are respectively installed on the inner side of the mounting blocks 17, a third spring 20 is provided at the lower end of the first extrusion plate 19, a silicone pad 21 is installed at the lower end of the third spring 20, an internal component 22 is provided on the inner side of the silicone pad 21, and a fourth spring 23 is provided at the upper end of the second extrusion plate 24.

[0028] Protective plates 18 are fixedly connected to the outer side of the mounting block 17, and second sealing rings 25 are provided through the upper and lower ends of the connector housing 1.

[0029] Mounting block 17 passes through second sealing ring 25, and second sealing ring 25 is slidably connected to mounting block 17.

[0030] Specifically, when the connector housing 1 falls, the protective plate 18 collides with the ground, generating an impact force. The protective plate 18 then compresses the mounting block 17, causing it to slide within the second sealing ring 25 and push the first compression plate 19 or the second compression plate 24 inward. During this movement, the first compression plate 19 or the second compression plate 24 impacts the third spring 20 or the fourth spring 23. The first compression plate 19 or the second compression plate 24, under the elasticity of the third spring 20 or the fourth spring 23, buffers the impact force. The buffered impact force then compresses the silicone pad 21. Due to the material of the fourth spring 23, it absorbs and cancels the impact force, thus preventing damage to the internal components 22 encased within the silicone pad 21. The second sealing ring 25 also blocks liquid from the ground. This allows the protective USB connector to buffer the impact during a fall, preventing damage to the internal components 22 and extending the lifespan of the protective USB connector.

[0031] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
