Abstract
Description
Technical Field
[0001] The utility model relates to an HDMI connector, in particular to a waterproof HDMI connector with a buckle structure. Background Art
[0002] HDMI, short for High-Definition Multimedia Interface, is a fully digital video and audio interface that can transmit uncompressed audio and video signals. HDMI can be used in devices such as set-top boxes, DVD players, personal computers, televisions, game consoles, integrated amplifiers, digital audio systems, and televisions.
[0003] In existing technology, HDMI connectors are secured to circuit boards by soldering. During installation, the HDMI connector on the circuit board is restrained by the electronic device's housing. However, some current electronic devices lack waterproof HDMI connectors, making it easy for water to enter the device through gaps in the connector. Some electronic devices do have waterproof HDMI connectors that are filled with silicone at the end of the connector, but this method is ineffective and can cause water to seep into other areas of the connector.
[0004] In addition, the HDMI connector in the prior art is easily loosened, resulting in poor contact.
[0005] In view of this, it is necessary to improve the existing HDMI connector. Utility Model Content
[0006] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a waterproof HDMI connector with a snap-fit structure. The purposes of designing the HDMI connector are: first, to improve the waterproof performance; second, to strengthen the fixing structure of the HDMI connector.
[0007] To solve the above technical problems, the present invention is implemented through the following solutions: The present invention provides a waterproof HDMI connector with a snap-fit structure, comprising an HDMI connector and a cable assembly electrically connected to the HDMI connector. The HDMI connector also includes a metal shell, wherein a first surface of the metal shell has at least one raised structural strip, and two L-shaped legs are provided on both sides of the tail end of the metal shell, and the ends of the two L-shaped legs are provided with through holes, and buckle strips with buckles are provided on both sides of the waist of the metal shell;
[0008] The metal shell also has a through cavity running through both ends, and a limiting notch is provided on the trailing edge of the first surface;
[0009] The HDMI connector includes a plastic block and an HDMI terminal portion connected to the plastic block. A protrusion is provided on the top surface of the plastic block. After the HDMI connector is installed in the through cavity, the protrusion is locked into the limiting notch.
[0010] The cable assembly includes a terminal block and a circuit board connected to the terminal block, and the terminal block is fixed to the contacts on the plastic block by welding;
[0011] The HDMI connector further comprises a silicone shell, which covers the side periphery of the metal shell through an injection molding process, seals the rear opening of the metal shell, and reserves the front opening of the metal shell.
[0012] Furthermore, after the silicone shell is fixed to the metal shell, the raised structural strip is sunken into the silicone shell.
[0013] Furthermore, there are two raised structural strips.
[0014] Furthermore, there are two limiting notches, and correspondingly, there are two protrusions, and the two protrusions are inserted into the two limiting notches one by one.
[0015] Furthermore, arc-shaped notches are provided at both ends of the circuit board.
[0016] Furthermore, a through hole is provided in the middle of the circuit board.
[0017] Compared with the prior art, the beneficial effects of the present invention are:

DETAILED DESCRIPTION
[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the scope of protection of the present invention. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0025] Example 1: The specific structure of the utility model is as follows:
[0026] Please refer to the attached Figure 1-3 The present invention discloses a waterproof HDMI connector with a snap-fit structure, comprising an HDMI connector 3 and a cable assembly 2 electrically connected to the HDMI connector 3. The HDMI connector also includes a metal shell 4 having at least one raised structural strip 42 on its first surface, with two raised structural strips 42 provided. Two L-shaped legs 45 are provided on either side of the rear end of the metal shell 4, each with a through-hole 46 at its end. Buckle strips 44 with buckle heads 47 are provided on both sides of the metal shell 4. The HDMI connector also includes a silicone shell 1, which is injection molded to cover the sides of the metal shell 4, seal the rear end of the metal shell 4, and reserve a front end. After the silicone shell 1 is secured to the metal shell 4, the raised structural strips 42 are sunken into the silicone shell 1. The raised structural strips 42 stabilize the connection between the metal shell 4 and the silicone shell 1, preventing the silicone shell 1 from moving within the metal shell 1.
[0027] After the silicone housing 1 is secured to the metal shell 4, the two buckle strips 44 have exposed sections with buckle heads 47 positioned opposite each other. When the circuit board 21 is installed, the buckle heads 47 snap into the buckle holes on the electronic device housing. Screws are then inserted through the vias 46 to secure the two L-shaped legs 45 to the electronic device housing. This dual-fixing structure ensures stable installation of the HDMI connector, preventing it from shaking or loosening during insertion and removal, thereby ensuring stable HDMI contact.
[0028] The metal shell 4 also has a through cavity 43 extending through both ends. A retaining notch 41 is provided on the trailing edge of its first surface, and its second surface is flat. The HDMI connector 3 comprises a plastic block 31 and an HDMI terminal portion 33 connected to the plastic block 31. A protrusion 32 is provided on the top surface of the plastic block 31. When the HDMI connector 3 is inserted into the through cavity 43, the protrusion 32 snaps into the retaining notch 41. There are two retaining notches 41, and correspondingly, there are two protrusions 32, with the two protrusions 32 snapping into the two retaining notches 41 in a one-to-one relationship.
[0029] The cable assembly 2 includes a terminal block 23 and a circuit board 21 connected to the terminal block 23. The terminal block 23 is welded and fixed to the contacts on the plastic block 31. The terminal block 23 is a "Z"-shaped structure with right angles at both corners.
[0030] The circuit board 21 has arc-shaped notches 22 at both ends, which are fixed by cap screws. A through hole 24 is provided in the middle of the circuit board 21, which is sleeved on the limit post in the electronic device housing to prevent the circuit board 21 from shaking.
[0031] The HDMI connector of the utility model is mostly used in outdoor advertising screens. The HDMI connector is connected to the HDMI cable, has good waterproof effect and stable data transmission.
[0032] In summary, the HDMI connector of this utility model utilizes a silicone injection molding process to coat the metal shell's lateral surfaces and rear port. The HDMI connector's socket can be plugged with a rubber plug, making the HDMI connector fully waterproof and enhancing the waterproof performance of the HDMI connector of this utility model. This utility model not only strengthens the HDMI connector's fixing structure, but also utilizes a dual fastening mechanism of snap-fit and screws to ensure a stable installation. The HDMI connector does not wobble or loosen during insertion or removal, thus ensuring stable HDMI contact.
[0033] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
