Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of dustproof connectors for electronic terminal equipment, and in particular to a dustproof connector for handheld electronic terminal equipment. Background Technology
[0002] Data ports are widely used peripheral connection ports on various electronic devices, especially computers and handheld electronic terminals, where they have become standard features. Besides connecting to other devices for data transfer, data ports can also be used to charge external devices. However, when in use, the open design of data ports makes them susceptible to dust accumulation, affecting normal operation. For example, a patent (CN220253593U) describes a dustproof port for handheld electronic terminals. A magnetic dustproof baffle slides to the end near the USB slot and is magnetically attracted, protecting the USB slot from dust and other impurities that could cause loose connections or poor contact. However, this dustproofing process requires manually pushing the magnetic dustproof baffle, which is inconvenient for small data interfaces, making manual manipulation of the baffle difficult. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a dustproof connector for handheld electronic terminal devices.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] Design a dustproof connector for a handheld electronic terminal device, including the electronic terminal device and a movable dustproof plate. The bottom of the electronic terminal device has a mounting hole, and the bottom of the inner cavity of the mounting hole is provided with a USB port. A plug is inserted into the mounting hole and communicates with the USB port. The two ends of the movable dustproof plate are connected to a rotating shaft. The inner sidewall of the mounting hole has a slot. The movable dustproof plate is set at the top of the mounting hole, and the rotating shaft is inserted into the slot.
[0006] Preferably, the top of the mounting hole is engaged with a baffle that shields the rotating shaft.
[0007] Preferably, the outer wall of the rotating shaft is fitted with a movable ring, and the outer wall of the movable ring is radially connected to a telescopic rod, the bottom of which is fixed to the inner wall of the mounting hole.
[0008] Preferably, a fixing ring is fixedly connected to the outer wall of the rotating shaft, a torsion spring is connected to the side wall of the fixing ring, the torsion spring is sleeved on the outer wall of the rotating shaft, and the end of the torsion spring is connected to a movable ring.
[0009] Preferably, the upper surface of the pair of movable dustproof plates is provided with a groove to facilitate the insertion of the plug.
[0010] Preferably, the mating joints of the pair of dustproof panels are bonded with mutually attractive magnetic sheets.
[0011] This utility model proposes a dustproof port for handheld electronic terminal devices. The advantages are as follows: By setting a pair of movable dustproof plates that can rotate around a pivot, when charging is needed, the external plug is pushed against the pair of movable dustproof plates, causing them to rotate and expose the dustproof port. Simultaneously, a pair of telescopic rods are compressed, increasing the distance between the movable dustproof plates and facilitating plug insertion for charging. After charging is complete, the plug is unplugged, and the pair of movable dustproof plates close under the push of the torsion spring and telescopic rods, effectively preventing external dust from entering the dustproof port. Compared to existing methods of using magnetic dustproof baffles by finger manipulation, this method is more convenient to use. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Reference Figure 1 , 25. A dustproof connector for a handheld electronic terminal device, comprising an electronic terminal device 1 and a movable dustproof plate 4. The bottom of the electronic terminal device 1 is provided with a mounting hole 2. The bottom of the inner cavity of the mounting hole 2 is provided with a USB port 6. A plug is inserted into the mounting hole 2 and communicates with the USB port 6. The two ends of the movable dustproof plate 4 are connected to a rotating shaft 9. The inner side wall of the mounting hole 2 is provided with a slot 3. The movable dustproof plate 4 is located at the top of the mounting hole 2. The rotating shaft 9 is inserted into the slot 3.
[0020] Reference Figure 1 , 5 The top of the mounting hole 2 is fitted with a baffle 7 that shields the rotating shaft 9. The outer wall of the rotating shaft 9 is fitted with a movable ring 12. The outer wall of the movable ring 12 is radially connected to a telescopic rod 11. The bottom of the telescopic rod 11 is fixed to the inner wall of the mounting hole 2. The telescopic rod 11 is an elastic telescopic rod. When not charging, the telescopic rod 11 pushes the rotating shaft 9 through the movable ring 12 to close a pair of movable dustproof plates 4, thereby achieving the dustproof function.
[0021] Reference Figure 4 , 5 A fixing ring 10 is fixedly connected to the outer wall of the rotating shaft 9. A torsion spring 8 is connected to the side wall of the fixing ring 10. The torsion spring 8 is sleeved on the outer wall of the rotating shaft 9. The end of the torsion spring 8 is connected to the movable ring 12. The torsion spring 8 is provided to assist a pair of movable dustproof plates 4 in flipping and closing. When the pair of movable dustproof plates 4 are flipped to the horizontal position, the side wall of the movable dustproof plate 4 abuts against the inner wall of the mounting hole 2. The upper end face of the pair of movable dustproof plates 4 is provided with a groove 5 for easy insertion of the plug. The mating part of the pair of movable dustproof plates 4 is glued with mutually attractive magnetic pieces. The magnetic pieces are attracted together to ensure that the pair of movable dustproof plates 4 are effectively closed.
