Description

Technical Field

[0001] This utility model relates to the field of connector cables, specifically to a waterproof and sealed HDMI connector cable. Background Technology

[0002] In existing technologies, HDMI cables, as a key component for high-definition audio and video signal transmission, are widely used in home theaters, office equipment, smart TVs, game consoles, and other scenarios. They mainly consist of a plug and a cable, with signal transmission achieved through the insertion and removal of the plug onto the corresponding interface. To meet basic usage requirements, existing HDMI cable plugs typically employ a standardized design, emphasizing ease of insertion and removal and signal transmission stability. They are mostly made of metal or plastic shells and integrate multiple sets of signal transmission pins internally.

[0003] However, existing HDMI cables have significant shortcomings in terms of sealing performance and environmental adaptability. First, the connection between the plug and the interface lacks an effective sealing structure, relying only on the mechanical tightness during plugging and unplugging to achieve a preliminary fit. In humid environments (such as near kitchens or bathrooms), dusty places (such as factory workshops), or scenarios where liquids may splash (such as KTVs or stage equipment), moisture and dust can easily penetrate into the interface through gaps, causing oxidation and corrosion of metal contacts, leading to problems such as signal transmission interruption, screen flickering, or short circuits. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned deficiencies and provide a waterproof and sealed HDMI cable. This cable features a multi-layered sealing structure at the connection between the plug and the interface, as well as at the junction of the cable and the plug. This solves the technical problem that existing technologies are prone to unstable signal transmission or even equipment damage due to seal failure in humid, dusty, or potentially liquid-contact environments.

[0005] The objective of this utility model is achieved through the following means:

[0006] A waterproof and sealed HDMI cable includes a plug and a cable body. The cable body is fixed to the input end of the plug. A protective cover is provided on the outside of the plug's insertion part. An internal thread is provided on the inner side of the protective cover. A silicone composite sealing ring is installed at the front end of the protective cover. An external thread is provided on the outside of the plug, and the external thread is connected to the internal thread through a threaded engagement. A sealing rib is embedded on the end face of the plug's insertion part. A stepped groove is provided in the middle of the outside of the plug.

[0007] Furthermore, the inner wall of the silicone composite sealing ring is provided with a first sealing inner ring, and the first sealing inner ring is integrally formed with the silicone composite sealing ring.

[0008] Furthermore, a second sealing inner ring is provided on the inner wall of the end of the protective cover away from the silicone composite sealing ring, and the second sealing inner ring is adhered and fixed to the protective cover. When the protective cover moves to the end of its travel, the second sealing inner ring contacts the external thread to improve the sealing performance.

[0009] Furthermore, the outer side of the protective cover near the silicone composite sealing ring has ventilation holes that are evenly distributed in a ring shape, and the ventilation holes are integrally formed with the protective cover.

[0010] Furthermore, a waterproof and breathable membrane is provided inside the ventilation hole, and the waterproof and breathable membrane is fixedly connected to the ventilation hole. The waterproof and breathable membrane is used to balance the air pressure inside and outside the protective cover.

[0011] Furthermore, the plug has anti-slip texture on the outer side near the wire body, and the anti-slip texture is integrally formed with the plug. The anti-slip texture improves the anti-slip performance of the plug, making it easier to plug and unplug the plug.

[0012] The beneficial effects of this utility model are:

[0013] This invention utilizes a protective cover with internal threads on the outside of the plug connector to achieve a tight connection with the external threads of the plug. The silicone composite sealing ring at the front of the protective cover fits tightly against the interface surface, forming the first layer of sealing barrier to prevent external moisture and dust from radial intrusion. Sealing ribs on the end face of the plug connector create an end-face seal with the internal structure of the interface when the plug is inserted, further preventing liquid from axially penetrating and protecting the internal metal contacts. Stepped grooves on the outside of the plug provide a more stable base for fixing the cable and plug, reducing gaps at the connection point caused by bending and improving the overall sealing performance. These designs collectively achieve multiple waterproof sealing effects, improving the stability of HDMI cables in humid, dusty, or potentially liquid-contaminated environments, and solving the problems of signal transmission failure, equipment damage, and shortened lifespan caused by insufficient sealing in existing technologies.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. This embodiment refers to... Figures 1-3 The present invention relates to a waterproof and sealed HDMI cable, comprising a plug 1 and a cable body 2. The cable body 2 is fixed to the input end of the plug 1. A protective cover 7 is provided on the outside of the plug part of the plug 1. An internal thread 13 is provided on the inner side of the protective cover 7. A silicone composite sealing ring 8 is installed on the front end of the protective cover 7. An external thread 5 is provided on the outside of the plug 1, and the external thread 5 is connected to the internal thread 13 by thread engagement. A sealing rib 6 is embedded on the end face of the plug part of the plug 1. A stepped groove 3 is provided in the middle of the outside of the plug 1.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the inner wall of the silicone composite sealing ring 8 is provided with a first sealing inner ring 9, and the first sealing inner ring 9 is integrally formed with the silicone composite sealing ring 8.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, a second sealing inner ring 12 is provided on the inner wall of the end of the protective cover 7 away from the silicone composite sealing ring 8, and the second sealing inner ring 12 is bonded and fixed to the protective cover 7. When the protective cover 7 moves to the end of its stroke, the second sealing inner ring 12 contacts the external thread 5 to improve the sealing performance.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the protective cover 7 has ventilation holes 10 evenly distributed in a ring on the outer side near the silicone composite sealing ring 8, and the ventilation holes 10 are integrally formed with the protective cover 7.

[0022] like Figure 1 and Figure 3 As shown, a waterproof and breathable membrane 11 is provided inside the ventilation hole 10, and the waterproof and breathable membrane 11 is fixedly connected to the ventilation hole 10. The waterproof and breathable membrane 11 is used to balance the air pressure inside and outside the protective cover 7.

[0023] like Figure 1 and Figure 2 As shown, the plug 1 has anti-slip texture 4 on the outer side near the wire body 2, and the anti-slip texture 4 is integrally formed with the plug 1. The anti-slip texture 4 improves the anti-slip performance of the plug 1, so as to facilitate plugging and unplugging the plug 1.

[0024] The working principle of the waterproof and sealed HDMI cable in this embodiment is as follows: When the plug 1 is inserted into the corresponding interface, the sealing rib 6 on the end face of the plug 1 first contacts the interface to form a preliminary seal. Subsequently, by rotating the protective cover 7, the internal thread 13 on its inner side engages with the external thread 5 on the outer side of the plug 1, causing the protective cover 7 to move towards the interface. When the protective cover 7 moves to the end of its travel, the silicone composite sealing ring 8 at its front end fits tightly against the interface surface, and the first sealing inner ring 9 on the inner wall of the silicone composite sealing ring 8 further enhances the sealing effect with the interface; the second sealing inner ring 12 on the inner wall of the protective cover 7 away from the silicone composite sealing ring 8 contacts the external thread 5, further improving the overall sealing performance. In addition, the waterproof and breathable membrane 11 inside the ventilation hole 10 on the outside of the protective cover 7 can balance the air pressure inside and outside the protective cover 7 while ensuring waterproofing, avoiding the air pressure difference from affecting the sealing effect. The stepped groove 3 on the outside of the plug 1 can assist in structural positioning, and the anti-slip texture 4 near the end of the cable body 2 can increase friction during insertion and removal, improving ease of use.

[0025] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
