Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of screen display connection cable adapters, specifically an HDMI male to female adapter. Background Technology
[0002] In the field of electronic device connectivity, HDMI male-to-female adapters play a crucial role, widely used for signal transmission between various display devices, computer hosts, and more. Traditional small HDMI male-to-female adapters typically encase their internal components in a rubber housing. However, during prolonged use, the PCB board inside the adapter generates heat, which is difficult to dissipate quickly due to the poor heat dissipation performance of the rubber housing. This not only causes the adapter's own temperature to rise continuously but also negatively impacts its performance, such as reduced transmission quality, signal stuttering, and distortion. Furthermore, it shortens the adapter's lifespan, increases equipment maintenance costs and replacement frequency, and causes inconvenience to users. Summary of the Invention
[0003] (a) Technical problems to be solved
[0004] The technical problem to be solved by this utility model is that traditional small HDMI male to female adapters usually enclose the internal components in a rubber shell. However, during long-term use, the PCB board inside the adapter will generate heat, and due to the poor heat dissipation performance of the rubber shell, the heat is difficult to dissipate quickly.
[0005] (II) Technical Solution
[0006] To solve the above problems, this utility model provides the following technical solution:
[0007] An HDMI male to female adapter includes a protective shell and a conversion component, wherein the protective shell covers the outside of the conversion component;
[0008] The adapter includes a male terminal, a female terminal, a PCB board, a thermally conductive silicone pad, and multiple heat sinks. The pins of the male terminal are electrically connected to the PCB board, and the pins of the female terminal are electrically connected to the PCB board. Both sides of the PCB board are provided with a thermally conductive silicone pad, and each thermally conductive silicone pad has multiple heat sinks on its outer cross-section. One end of each heat sink is connected to the thermally conductive silicone pad, and the other end passes through the protective shell and extends to the outside of the protective shell.
[0009] Furthermore, the protective shell is provided with heat dissipation cavities, and there are two heat dissipation cavities, which are symmetrically arranged on the upper and lower surfaces of the protective shell.
[0010] Furthermore, the heat sink passes through the protective shell and extends into the heat dissipation cavity, and the height of the end of the heat sink near the heat dissipation cavity is set lower than the height of the outer end face of the protective shell.
[0011] Furthermore, the protective shell is also provided with a detachable anti-touch grille, which is installed in the heat dissipation cavity by means of an interference fit.
[0012] Furthermore, the anti-touch fence is made of hard plastic material, and multiple heat dissipation vents are evenly provided on the anti-touch fence.
[0013] Furthermore, the heat sink is made of either a metal heat sink or a ceramic heat sink.
[0014] (III) Beneficial Effects
[0015] The beneficial effects of this utility model are:
[0016] 1. This utility model forms a highly efficient heat dissipation system by setting thermally conductive silicone pads on both sides of the PCB board and connecting multiple heat sinks, with the heat sinks extending to the outside of the protective shell 1. Compared with traditional adapters encased in rubber shells, it can quickly dissipate the heat generated by the PCB board, effectively reducing the internal temperature of the adapter and avoiding transmission quality degradation problems caused by overheating, such as signal stuttering and distortion. This ensures the stability and smoothness of signal transmission and greatly improves the user experience.
[0017] 2. The removable anti-touch grille on the protective shell effectively prevents users from accidentally touching the heat sink and causing burns, ensuring personal safety during operation and use. On the other hand, its removable feature facilitates dust cleaning of the heat sink later, ensuring continuous and efficient heat dissipation and further maintaining the stable performance of the adapter, providing double protection for long-term safe use.
[0018] 3. The height of the heat sink near the heat dissipation cavity is lower than the outer end face of the protective shell 1, which does not affect the heat dissipation effect, prevents scratching external objects, and takes into account the appearance and portability of the product. The anti-touch fence is made of hard plastic material, which has a certain strength and toughness and can withstand minor daily collisions. The evenly distributed heat dissipation vents on it ensure the protective function without hindering heat dissipation. Attached image description:

[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] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0028] Please see Figures 1-5 The HDMI male to female adapter shown includes a protective shell 1 and a conversion component 2, wherein the protective shell 1 covers the outside of the conversion component 2;
[0029] The converter 2 includes a male terminal 201, a female terminal 202, a PCB board 203, thermally conductive silicone pads 204, and multiple heat sinks 205. The pins of the male terminal 201 are electrically connected to the PCB board 203 to receive signals from external signal sources and accurately transmit them to the PCB board 203 for processing. The pins of the female terminal 202 are also electrically connected to the PCB board 203 to stably output the processed signals to the connected device. Furthermore, a thermally conductive silicone pad 204 is tightly attached to both sides of the PCB board 203. The thermally conductive silicone pad 204 has excellent thermal conductivity, enabling it to quickly and evenly absorb the heat generated by the PCB board 203 during operation. Multiple heat sinks 205 are neatly arranged on the outer surface of each thermally conductive silicone pad 204. One end of each heat sink 205 is connected to the thermally conductive silicone pad 204 to ensure efficient heat transfer, while the other end passes through the protective shell 1 and extends to the outside of the protective shell 1, forming a heat dissipation channel that directly contacts the outside air, accelerating heat dissipation.
[0030] The protective shell 1 is provided with heat dissipation cavities 3, and there are two heat dissipation cavities 3, which are symmetrically arranged on the upper and lower surfaces of the protective shell 1. The design of the heat dissipation cavities 3 provides a larger heat dissipation space for the heat sink 205, and air can flow freely in the cavity to carry away the heat on the heat sink 205, further improving the heat dissipation efficiency.
[0031] The heat sink 205 passes through the protective shell 1 and extends into the heat dissipation cavity 3. The height of the end of the heat sink 205 near the heat dissipation cavity 3 is set lower than the height of the outer end face of the protective shell 1. This ensures heat dissipation and prevents the heat sink 205 from accidentally scratching external objects. At the same time, it avoids affecting the overall appearance and portability of the adapter due to excessive protrusion.
[0032] The protective shell 1 is also equipped with a detachable anti-touch grille 4, which is installed in the heat dissipation cavity 3 via an interference fit. The anti-touch grille 4 adopts a modular design, and its contact part with the heat dissipation cavity 3 has a certain degree of elasticity, making it easy to install and remove. During installation, simply align the anti-touch grille 4 with the heat dissipation cavity 3 and press it gently to fix it in place; during removal, simply pull it outward with a little force. This detachable structure not only effectively prevents users from accidentally touching the heat sink 205 and causing burns or other safety issues, but also facilitates the cleaning of dust accumulated on the heat sink 205 later, ensuring that the heat sink 205 always maintains good heat dissipation performance.
[0033] The anti-collision fence 4 is made of hard plastic material, which has a certain strength and toughness and can withstand minor collisions in daily use. The anti-collision fence 4 is evenly provided with multiple heat dissipation vents 5. The shape of the heat dissipation vents 5 can be round, square or oval, etc., to ensure that the heat dissipation efficiency is not affected while providing protection, so that air can pass smoothly through the heat dissipation cavity 3 and the heat dissipation fins 205 for heat exchange.
[0034] The heat sink 205 can be made of either a metal heat sink 205 or a ceramic heat sink 205. Utilizing the good thermal conductivity of metals (such as aluminum or copper; aluminum is low-cost, lightweight, and has good thermal conductivity, while copper has superior thermal conductivity but is relatively expensive) or ceramics, it quickly conducts heat away from the PCB board 203. Ceramic heat sinks also possess certain high-temperature resistance and insulation properties, making them safer and more reliable for use in certain special environments.
[0035] The embodiments are detailed, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
