Technical Field

[0001] This utility model relates to the field of dust plug technology, and in particular to a dust plug for a mobile phone charging port. Background Technology

[0002] During mobile phone use, the dust and water resistance of the charging port is an extremely important feature;

[0003] The existing dust plugs have a simple structure and are easy to fall off or be lost during normal use after being inserted into the charging port. Similarly, the same problem can occur if the dust plug is not removed during charging or stored improperly, which reduces the dustproof and waterproof effect and causes inconvenience to users.

[0004] Currently, there is a type of silicone phone case on the market that includes a dust plug in its one-piece design, which can protect the charging port from external environmental influences to a certain extent. However, this type of silicone phone case is only suitable for soft-shell materials, and not all soft-shell phone case manufacturers will reserve space for the dust plug design in their products. This limitation prevents users from generally enjoying the convenience brought by the dust plug when purchasing soft-shell phone cases, thus affecting the product's popularity and user experience.

[0005] Based on the above problems, we propose a dust plug for mobile phone charging ports. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by designing a dust plug that works in conjunction with a phone case. The dust plug can be inserted into the charging port and remains fixed to the phone case when removed, thus preventing it from falling off or being lost.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A dust plug for a mobile phone charging port includes a dust plug, a connecting part on one side of the dust plug, and a snap-fit ​​part on the other side of the connecting part, the snap-fit ​​part snapping into the mobile phone and the mobile phone case on the charging port side of the mobile phone case.

[0009] Furthermore, the dust plug is provided with a charging port fitting protrusion, and the charging port fitting protrusion matches the mobile phone charging port.

[0010] Furthermore, the dust plug has a cover on its outer side, and the outer side of the cover has an easy-pull-out protrusion.

[0011] Furthermore, the dust plug has a metal reinforcing sheet inside.

[0012] Furthermore, the connecting part is provided with metal connecting ribs inside, and the metal connecting ribs are arranged in multiple vertical rows and bonded together.

[0013] Furthermore, the snap-fit ​​portion is provided with a metal reinforcing sheet, the thickness of which is 0.2mm-0.4mm.

[0014] Furthermore, the two ends of the metal connecting rib are welded to the metal reinforcing sheet and the metal reinforcing thin sheet, respectively.

[0015] Furthermore, the dust plug, connecting part, and snap-fit ​​part are all made of rubber, and the thickness of the snap-fit ​​part is less than 0.8mm.

[0016] Furthermore, the two ends of the snap-fit ​​part are provided with arc ears, which are made of rubber material and are integral with the snap-fit ​​part.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The dust plug of this utility model is snapped between the phone and the phone case on the charging port side of the phone case via a snap-fit ​​part, so that the dust plug can be firmly fixed on the phone case after being inserted into the charging port. Even if the dust plug is pulled out for charging, the dust plug is still connected to the phone case through the connecting part, avoiding the problem of traditional dust plugs being easy to fall off or be lost, and greatly improving the user's convenience.

[0019] 2. The dust plug has a metal reinforcing plate inside, and multiple sets of vertically bonded metal connecting ribs inside the connecting part. The snap-fit ​​part has a metal reinforcing sheet.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be provided below with reference to relevant embodiments, and several embodiments of this utility model will be given. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this utility model more thorough and complete.

[0030] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example 1

[0032] like Figure 1-4 As shown, this utility model provides a technical solution: a dust plug for a mobile phone charging port.

[0033] It includes a dust plug 1, a connecting part 2, and a snap-fit ​​part 3. The dust plug 1 is the core component that directly seals the charging port. The connecting part 2 serves as a flexible transition section that connects the dust plug 1 and the snap-fit ​​part 3. The snap-fit ​​part 3 is fixed between the phone case and the edge of the phone through an elastic snap-fit ​​method, thus realizing the integrated design of the dust plug 1 and the phone case.

[0034] The specific connection structure is as follows: a connecting part 2 is provided on one side of the dust plug 1, and a snap-fit ​​part 3 is provided on the other side of the connecting part 2. The snap-fit ​​part 3 snaps into the phone and the phone case on the charging port side of the phone case.

[0035] The dust plug 1 and the snap-fit ​​part 3 are physically connected through the connecting part 2. When the user pulls out the dust plug 1, the connecting part 2 can move synchronously with the dust plug 1, but the snap-fit ​​part 3 remains fixed, which completely solves the problem that the traditional dust plug 1 is easy to lose. Example 2

[0036] like Figure 1-4 As shown, the dust plug 1 has a charging port fitting protrusion 11, which matches the mobile phone charging port (designed according to different mobile phone models). The seal is achieved through the elastic fit of the rubber material, effectively preventing dust and water droplets from entering.

[0037] The dust plug 1 has a cover 12 on the outside, and an easy-pull protrusion 13 on the outside of the cover 12. The diameter of the cover 12 is 2mm larger than that of the main body of the dust plug 1, forming an operating platform. The easy-pull protrusion 13 can be a protrusion with a height of 3mm and the surface is treated with anti-slip texture. Users can easily pinch and pull out the dust plug 1 with their thumb and forefinger.

[0038] The dust plug 1 has a metal reinforcing plate 14 inside, which increases the local structural strength to prevent deformation caused by repeated insertion and removal.

[0039] The connecting part 2 is provided with a metal connecting rib 21. The metal connecting rib 21 has multiple sets of vertically bonded together. It is made of four sets of copper alloy thin sheets with a thickness of 0.08mm bonded together, with a total thickness of 0.32mm. It is welded between the metal reinforcing sheet 14 and the metal reinforcing sheet 31. The metal connecting rib 21 is wrapped with rubber to achieve flexible bending, which not only ensures the structural stability when the dust plug 1 is pulled out, but also avoids the connecting part 2 from breaking due to frequent bending.

[0040] The snap-fit ​​part 3 is provided with a metal reinforcing sheet 31, the thickness of which is 0.2mm-0.4mm. This increases the local rigidity and prevents the snap-fit ​​part 3 from deforming after long-term use.

[0041] The two ends of the metal connecting rib 21 are welded to the metal reinforcing sheet 14 and the metal reinforcing sheet 31, respectively.

[0042] The aforementioned metal reinforcing sheet 14, metal connecting rib 21, and metal reinforcing sheet 31 can be made of ferrous metal. Example 3

[0043] like Figure 1-4 As shown, the dust plug 1, the connecting part 2 and the snap-fit ​​part 3 are all made of rubber, and the thickness of the snap-fit ​​part 3 is less than 0.6mm.

[0044] The two ends of the snap-fit ​​part 3 are provided with arc ears 32, which are made of rubber and are integral with the snap-fit ​​part 3.

[0045] Based on embodiment 3, the fixing principle of the snap-fit ​​part 3 is as follows:

[0046] The snap-fit ​​part 3 is made of rubber material with a thickness of ≤0.8mm. It is snapped into the gap between the mobile phone and the mobile phone case through elastic deformation (the gap width is usually 0.5-0.8mm). The friction and deformation rebound force of the rubber are used to achieve a stable snap-fit.

[0047] Even better, the design of the two curved ears 32 at both ends can increase the contact area of ​​the latch, prevent the latch part 3 from sliding, reduce local pressure, and prevent scratches on the edge of the phone.

[0048] The working process of this utility model:

[0049] Step 1: Initial Installation

[0050] When the user puts the phone into the phone case, the latching part 3 is placed at the edge of the phone's charging port. After the phone case is rotated up, the latching part 3 is inserted into the gap between the phone case and the phone.

[0051] Check if the dust plug 1 can be inserted into the charging port and confirm that the connection part 2 is not twisted or stretched.

[0052] Step 2: Daily dust prevention

[0053] The dust plug 1 fits snugly against the charging port via the protrusion 11. The elastic sealing layer made of rubber can block particles with a diameter of ≥0.1mm and IPX4 splash water.

[0054] The connecting part 2 remains in a naturally relaxed state, and the metal connecting rib 21 is isolated from the outside world by a rubber wrapping layer to prevent oxidation.

[0055] Step 3: Charging Operation

[0056] The user pinches the easy-pull protrusion 13 with their thumb and forefinger and applies a force of about 2N in the direction perpendicular to the charging port to pull out the dust plug 1.

[0057] The connecting part 2 bends synchronously with the dust plug 1, the metal connecting rib 21 undergoes elastic deformation, and the snap-fit ​​part 3 remains fixed in the gap of the mobile phone case.

[0058] After charging is complete, the user presses the dust plug 1 against the charging port, and it automatically returns to its original position through the guiding action of the protrusion 11 that fits into the charging port.

[0059] Step 4: Maintenance and Replacement

[0060] If you need to remove the dust plug 1 (e.g., to replace the phone case), remove the phone case and directly take out the card connector 3 and the whole unit.

[0061] The technical advantages of the present invention can be summarized through the above embodiments:

[0062] Structural stability: Through the rigid support of the metal reinforcing sheet 14 and the metal reinforcing sheet 31, combined with the flexible transition of the metal connecting rib 21, the deformation of the dust plug 1 after 1000 insertion and removal tests is ≤0.1mm.

[0063] Ease of use: The design of the easy-pull protrusion 13 reduces the pulling force by 40% compared to the traditional dust plug 1, increasing the success rate of one-handed operation to 98%.

[0064] Compatibility: The thickness of the card connector 3 and the curvature of the curved ear 32 are adapted to mainstream mobile phone cases, covering more than 99% of smartphone models.

[0065] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
