Description

Technical Field

[0001] This utility model relates to the field of HDMI cable connector technology, specifically a dustproof HDMI cable connector. Background Technology

[0002] An HDMI connector is a high-definition multimedia interface connector used to connect devices. It can simultaneously transmit high-quality audio and video signals, employing a fully digital transmission method to avoid the loss problems of analog signal transmission and ensure lossless audio and video transmission. For example, an HDMI connector with announcement number CN215645278U includes a connecting block, a connector head fixed to the side wall of the connecting block, an installation groove on the side wall of the connecting block, a fixing rod fixed to the inner wall of the installation groove, and a rotating block rotatably connected to the circumferential side wall of the fixing rod via a bearing. The rotating block has a wire groove on its side wall. The connecting block has two symmetrically arranged limiting devices inside, and the installation groove has multiple suction devices inside. Each limiting device includes a sliding rod that slides through and slides along the upper end of the connecting block. By setting up a sliding rod that can slide up and down and a rotating block that can rotate along the fixing rod, the limiting rod and limiting groove's limiting and separation relationship can be quickly adjusted, allowing for arbitrary adjustment of the rotating block's installation angle. This adapts to the installation of HDMI connectors in more confined environments, effectively increasing the applicability of HDMI connectors. However, this HDMI cable connector still has the following drawbacks in actual use:

[0003] Existing HDMI cable connectors have poor dust protection. When the HDMI cable connector is not in use, its connection terminals are directly exposed, allowing dust to enter the connection terminals. When the HDMI cable connector is connected to the device again, the dust can cause unstable signal transmission. To address these issues, there is an urgent need for innovative design based on the existing HDMI cable connector. Utility Model Content

[0004] The purpose of this invention is to provide a dustproof HDMI cable connector to solve the problem of poor dustproof performance of existing HDMI cable connectors mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dustproof HDMI cable connector, including a connector head, one end of which is provided with a connecting wire, and the other end of which is equipped with a connecting terminal, and a mounting plate is fixed to the end of the connecting terminal near the connector head;

[0006] It also includes: an adjustment mechanism disposed between the mounting plate and the connector, the adjustment mechanism being used to adjust the retraction and extension of the connector terminal, the connector having a through groove at the end away from the connecting wire, and the connector terminal extending through the through groove after being extended, the inside of the through groove being provided with a dustproof component, the dustproof component being used to prevent dust when the connector terminal is retracted and extended, and the surface of the connector terminal having a groove.

[0007] Preferably, the adjustment mechanism includes a connecting plate disposed on the top of the mounting plate, and the connecting plate and the mounting plate are slidably connected, and the bottom of the connecting plate is connected to the interior of the mounting plate by a spring.

[0008] Preferably, a fixing groove is provided on the connector head on the outer side of the connecting plate, and dustproof cloth is provided on both sides of the connecting plate, and the dustproof cloth is slidably disposed inside the fixing groove.

[0009] Preferably, the end of the dustproof cloth away from the connecting plate is wound around the take-up shaft, and the take-up shaft is located on the inner wall of the connector, and a spiral spring is provided at the rotation point of the take-up shaft and the connector.

[0010] Preferably, both ends of the connecting plate are fixed with fixing rods, and the fixing rods and limiting holes are engaged, and the limiting holes are evenly spaced on the inner top surface of the connector.

[0011] Preferably, the dustproof assembly includes a baffle disposed on the inner wall of the connector, and the side of the baffle near the mounting plate has an inclined structure, and the height of the two baffles is greater than the height of the through groove.

[0012] Preferably, a support rod runs through the interior of the baffle, and the support rod is fixed to the inner wall of the connector. The baffle and the support rod are slidably connected, and a spring is provided between the baffle and the connector.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this dustproof HDMI cable connector has a good dustproof effect. The connection terminal can extend outside the connector when in use and can be stored inside the connector when not in use, avoiding direct exposure to the outside and preventing dust from entering. This can improve the stability of signal transmission during subsequent connections. The specific details are as follows:

[0014] 1. Press down on the connecting plate and slide it in the mounting plate, thereby causing the fixing rod to separate from the limiting hole. When the connecting plate is pushed, the mounting plate and the connecting terminal can be moved. When the connecting terminal moves and contacts the baffle, its inclined surface can push the baffle to slide on the support rod. In this way, the two baffles move away from each other, making it easier for the connecting terminal to extend out of the connector.

[0015] Furthermore, after adjusting the connecting terminal, release the pressure on the connecting plate. The spring's rebound will cause the connecting plate to rise and the fixing rod to lock into the corresponding limiting hole. This allows the length of the connecting terminal to extend to be adjusted according to the different interfaces of the connected equipment.

[0016] Furthermore, when the two baffles are not in contact with the connecting terminals, they can move closer to each other through the spring's rebound, blocking the through slot and preventing external dust from entering.

[0017] 2. When the connecting plate is pushed, the dustproof cloth 7 can move synchronously. The dustproof cloth extends and is wound up on the take-up shaft, which can ensure that the position of the fixing groove is blocked, and external dust will not enter the interior of the connector during adjustment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-7 The present invention provides the following technical solution:

[0028] Example 1: To solve the problems existing in the prior art, this example provides a dustproof HDMI cable connector, including a connector 1, a connecting wire 2 at one end of the connector 1, and a connecting terminal 3 at the other end of the connector 1. A mounting plate 4 is fixed to the end of the connecting terminal 3 near the connector 1. The connector also includes an adjustment mechanism disposed between the mounting plate 4 and the connector 1. The adjustment mechanism is used to adjust the retraction and extension of the connecting terminal 3. A through groove 11 is provided at the end of the connector 1 away from the connecting wire 2. The connecting terminal 3 extends through the through groove 11. A dustproof component is provided on the inner side of the through groove 11. The dustproof component is used to prevent dust when the connecting terminal 3 is retracted and extended. A groove 31 is provided on the surface of the connecting terminal 3.

[0029] Most existing HDMI cable connectors have a fixed connection between the connection terminal 3 and the connector 1, which cannot extend when in use and retract when not in use. The adjustment mechanism includes a connection plate 5 located on top of the mounting plate 4, and the connection plate 5 and the mounting plate 4 are slidably connected. The bottom of the connection plate 5 is connected to the inside of the mounting plate 4 via a spring. A fixing groove 6 is provided on the connector 1 on the outer side of the connection plate 5, and dustproof cloths 7 are provided on both sides of the connection plate 5, and the dustproof cloths 7 are slidably located inside the fixing groove 6. The end of the dustproof cloth 7 away from the connection plate 5 is wound around a winding shaft 8, and the winding shaft 8 is located on the inner wall of the connector 1. A spiral spring is provided at the rotation point of the winding shaft 8 and the connector 1. Fixing rods 9 are fixed at both ends of the connection plate 5, and the fixing rods 9 and the limiting holes 10 are engaged. The limiting holes 10 are evenly spaced on the inner top surface of the connector 1. Figure 4 As shown, the connecting terminal 3 is stored inside the connector 1 when not in use. When the connecting terminal 3 needs to be connected to the device, as shown... Figures 4-7 As shown, firstly, press down on the connecting plate 5 to slide it in the mounting plate 4, thereby causing the fixing rod 9 to separate from the limiting hole 10. When the connecting plate 5 is pushed, the mounting plate 4 and the connecting terminal 3 can be moved in the connector 1, pushing the connecting terminal 3 to the outside of the connector 1 to connect with the equipment. When the connecting terminal 3 moves and contacts the baffle 12, its inclined surface can push the baffle 12 to slide on the support rod 13, so that the two baffles 12 are far apart, making it convenient for the connecting terminal 3 to extend out of the connector 1. After the connecting terminal 3 extends, the groove 31 on its surface can engage with the inside of the connector 1. After adjusting the connecting terminal 3, release the pressure on the connecting plate 5. The spring's elasticity can cause the connecting plate 5 to rise, and cause the fixing rod 9 to be locked in the corresponding limiting hole 10. The length of the connecting terminal 3 can be adjusted according to the different interfaces of the connected equipment.

[0030] Example 2: Existing HDMI cable connectors have poor dustproof performance. When the HDMI cable connector is not in use, its connection terminal 3 is directly exposed, allowing dust to enter. When the HDMI cable connector is reconnected to the device, dust can cause unstable signal transmission. Therefore, this example addresses this issue with the following technical solution: the dustproof component includes a baffle 12 disposed on the inner wall of the connector 1, with the baffle 12 having a sloping structure on the side near the mounting plate 4, and the height of both baffles 12 being greater than the height of the through groove 11; a support rod 13 passes through the interior of the baffle 12 and is fixed to the inner wall of the connector 1, with the baffle 12 and support rod 13 being slidably connected; a spring is also provided between the baffle 12 and the connector 1. Figure 4 As shown, when the connecting terminal 3 is not in use and is stored inside the connector 1, the two baffles 12 are not in contact and can approach each other through the elasticity of the spring, blocking the position of the through groove 11 to prevent external dust from entering. When the connecting plate 5 is pushed, the dustproof cloth 7 can move synchronously. The dustproof cloth 7 extends and is wound up on the take-up shaft 8, which can ensure that the position of the fixing groove 6 is blocked. During adjustment, external dust will not enter the interior of the connector 1. When the dustproof cloth 7 is not pulled, the take-up shaft 8 is driven to rotate in the opposite direction through the spiral spring, and the dustproof cloth 7 is automatically wound up.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
