Description

Technical Field

[0001] This utility model relates to a sealed and reliable HDMI connector. Background Technology

[0002] HDMI stands for High Definition Multimedia Interface, a digital video / audio interface technology. It's a dedicated digital interface suitable for image transmission, capable of simultaneously transmitting audio and video signals at a maximum data transfer rate of 18Gbps without requiring digital-to-analog or analog-to-digital conversion before signal transmission. HDMI's extra capacity can be used for future upgrades to audio and video formats. Since a 1080p video and an 8-channel audio signal require less than 0.5GB / s, HDMI has significant headroom, allowing a single cable to connect a DVD player, receiver, and PRR. With technological advancements, various types of HDMI cables have emerged on the market.

[0003] The core of an existing HDMI cable is a key component that needs to be sealed to ensure its normal operation. This invention aims to provide a reliably sealed structure. Summary of the Invention

[0004] The purpose of this invention is to provide a reliably sealed HDMI connector to solve the problems mentioned in the background section. To achieve the above objective, this invention provides the following technical solution:

[0005] A reliably sealed HDMI connector includes an upper shell, a lower shell, a cable guide, and a main core. The upper and lower shells cover the main core. The upper shell has a plug at its front end, and the lower shell has a socket of the same size as the plug. The plug is inserted into the socket. The cable guide has a fitting opening at its front end, and a locking opening at the fitting opening. The upper shell has a locking block. The rear ends of the upper and lower shells are interference-fitted into the fitting opening, and the locking block is positioned in the locking opening.

[0006] Furthermore, a guide ramp is provided at the rear end of the locking block.

[0007] Furthermore, a sealing ring is provided at the front end of the main core, and the sealing ring fits against the inner walls of the upper and lower shells.

[0008] The beneficial effects of this utility model are as follows: In this utility model, the interference fit of the rear end of the upper shell and the lower shell into the fitting port will cause the front end to expand with a pre-tightening force. Under such circumstances, the internal seal will not be tight. Therefore, by setting a plug and a socket at the front end, the plug can be inserted into the socket to restrict the front end from expanding and achieve a sealing effect.

[0013] It should be noted that the accompanying drawings are not necessarily drawn to scale, but are shown only in a schematic manner without affecting the reader's understanding. Detailed Implementation

[0014] 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.

[0015] In this invention, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this invention and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0016] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0017] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0018] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0019] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0020] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0021] like Figures 1 to 3 As shown, a reliably sealed HDMI connector includes an upper shell 1, a lower shell 2, a cable guide 3, and a main core 4. The upper shell 1 and the lower shell 2 cover the main core 4. The upper shell 1 has a plug 11 at its front end, and the lower shell 2 has a socket 21 of the same size as the plug 11. The plug 11 is inserted into the socket 21. The cable guide 3 has a fitting opening 31 at its front end, and a locking opening 32 is provided at the fitting opening 31. The upper shell 1 has a locking block 12. The rear ends of the upper shell 1 and the lower shell 2 are interference-fitted into the fitting opening 31, and the locking block 12 is placed in the locking opening 32.

[0022] In this invention, the interference fit of the rear end of the upper shell 1 and the lower shell 2 into the fitting port will cause the front end to expand with a pre-tightening force. Under such circumstances, the internal seal will not be tight. Therefore, by setting a plug and a socket at the front end, the plug can be inserted into the socket to restrict the front end from expanding and achieve a sealing effect.

[0023] Furthermore, the rear end of the locking block 12 is provided with a guide slope 121.

[0024] Furthermore, a sealing ring 41 is provided at the front end of the main core 4, and the sealing ring 41 fits against the inner wall of the upper shell 1 and the lower shell 2.

[0025] It should also be noted that, without conflict, the embodiments of this utility model and the features therein can be combined with each other to obtain new embodiments.
