Abstract
Description
Technical Field
[0001] The utility model relates to the field of data connectors, in particular to an HDMI cable connector that is easy to dissipate heat. Background Art
[0002] HDMI (High-Definition Multimedia Interface) is a fully digital video and audio transmission interface that can transmit uncompressed audio and video signals. HDMI can be used in devices such as set-top boxes, DVD players, personal computers, TVs, game consoles, integrated amplifiers, digital audio systems, and TVs. HDMI can transmit audio and video signals simultaneously. Since the audio and video signals use the same wire, it greatly simplifies the installation difficulty of the system circuit.
[0003] However, precisely because the audio and video signals use the same wire, when the HDMI connector is working (especially in a high-load working state), heat is generated relatively quickly inside it. Currently, most HDMI connectors adopt a fully enclosed structure, and the internal terminals, PCBs, chips, etc. are all filled by injection molding, so the heat cannot be effectively dissipated, and the accumulated heat is serious. Moreover, once this type of assembly method is formed, the internal stress is relatively large, and the connector is easily deformed or burst due to working heat, external collision, and extrusion.
[0004] In view of this, the technical solution of this application proposes an HDMI cable connector that is easy to dissipate heat. It not only provides a good heat conduction and dissipation structure but also changes the assembly and processing technology. By adopting a layer-by-layer sleeved form, it is not easy to deform after long-term use, and the internal stress is reduced, effectively extending the service life. Summary of the Utility Model

Contact baffles are provided on both sides of the terminal bracket. The contact baffles are located between the inner mold and the terminal bracket, cover the connection terminals and the pin areas, and are in close contact with the inner wall of the inner mold.

[0022] As follows:
[0023] Please refer to the attached Figure 1-2
[0024] The main structure includes a plug body 1. The plug body 1 includes a plug connector 12, and an inner mold 11 sleeved outside the plug connector 12 and used for dissipating the working heat of the plug connector 12. An outer housing 10 is sleeved outside the inner mold 11. The plug connector 12 includes a terminal bracket 121 and connection terminals 120 arranged on one side of the terminal bracket 121. Pins 123 are formed at the tails of the connection terminals 120. Contact baffles 14 are arranged on both sides of the terminal bracket 121. The contact baffles 14 are located between the inner mold 11 and the terminal bracket 121, and the contact baffles 14 cover the areas of the connection terminals 120 and the pins 123 and are in close contact with the inner wall of the inner mold 11.
[0025] The working principle is as follows:
[0026] During assembly, first cover the contact baffles 14 on both sides of the plug connector 12 to ensure that the contact baffles 14 on both sides completely cover the area from the connection terminals 120 to the pins 123. At this time, the terminal slots 140 of the contact baffles 14 will cover the connection terminals 120, and the bottom of the contact baffles 14 will cover the pins 123. Then, insert the plug connector 12 with the contact baffles 14 into the inner mold 11 and fix it through the terminal bracket 121. Finally, install the outer housing 10 to complete the assembly. Compared with the current overmolding and potting and other overshell assembly methods, the HDMI connector structure provided by this solution has small internal stress after assembly and has a long service life.
[0027] During operation, the contact baffles 14 connected to the terminals and arranged in the plug body 1 can conduct the working heat of the terminals and the terminal pins 123 to the inner mold 11 wrapped outside. The inner mold 11 is a metal part (such as aluminum or copper, etc.) with strong heat conduction performance, and the inner mold 11 fully conducts the internal heat through the outer housing 10.
[0028] A preferred embodiment in the present utility model: A hollow position 100 for further dissipating the heat of the inner mold 11 is opened on the outer housing 10.
[0029] Hollow positions 100 can also be opened on the outside of the outer housing 10 to further improve the heat conduction performance.
[0030] A preferred embodiment of the present utility model: The contact baffle 14 further includes terminal card slots 140 that are in close contact with each connection terminal 120. The contact baffle 14 is a copper baffle structure, and each terminal card slot 140 provided on the copper baffle is a die-cast groove structure.
[0031] The main functions of the terminal card slots 140 are to fix (stabilize) each connection terminal 120 and to make full contact with each connection terminal 120. A large amount of heat generated by the connection terminal 120 during operation is conducted to the contact baffle 14 through the terminal card slots 140.
[0032] A preferred embodiment of the present utility model: Both ends of the contact baffle 14 are provided with connectors 141 for connection. The connector 141 is a snap 122 connection structure.
[0033] The contact baffle 14 is a two-sided snap structure, and the function of clamping and fixing the connection terminal 120 is realized through the connector 141.
[0034] A preferred embodiment of the present utility model: The inner mold 11 is an integral aluminum shell structure.
[0035] The inner mold 11 is an aluminum shell structure. Aluminum is a good conductor of heat, with a thermal conductivity of 237 W / (m·k), second only to silver, copper, and gold in terms of thermal conductivity. Moreover, it is easy to be processed into a shell, with light weight and low cost, and is suitable for mass production.
[0036] The above are only the preferred embodiments of the technical solution of the present utility model, and do not limit the patent scope of the technical solution of the present utility model accordingly.
